IN THE HEAT OF THE SUMMER 2024

 

It’s been a while, and I just need to organize my thoughts as we face a most critical crossroad for the future of America and the world.  It all boils down to Climate Change!  We’ve been aware of it for quite some time, and as predicted, the changes and impacts are escalating at an exponential rate.  Record heat, countless tornados, massive hurricanes, record flooding, enormous wildfires, even shark attacks…these are just a few of the manifestations of what is going with temperature changes in our atmosphere, our oceans, and our land. We focus on the U.S., but this is happening all over the globe.  Our politicians, money powers, and other “leaders” still don’t get it, or are too ignorant to understand the huge impacts now coming to our economy, environment, infrastructures, and most important to all the people who will be directly affected.  The progressives…politicians, environmental organizations, and everyone else who can…  should be shouting it out, rather than continuing with fear that the opposition will attack them saying there is no proof, it’s all just a hoax.  Tell it like it is, instead of naming it an existential threat, which most people don’t understand.  Buy TV ads, hold press conferences, stage demonstrations...be a real thorn in the side of the powers that be so the issues cannot be avoided. 

 A most sobering fact is that regardless of what we decide to do right now will not lessen or correct the changes for many years to come.  The time lag for solutions to begin to work gives us little hope for a return to normal.  Society, with its ever-increasing population and affluence, will suffer from changes in food production, potable water scarcity, land degradation, and more importantly the social repercussions that will come from increased migration and immigration, homelessness, poor nutrition and disease, and ultimately social decay and war.  Like the fall of the many empires throughout history, the fall of this capitalistic empire looms over the next few decades.  It’s not the end of the world, but the end to the overconsuming and unsustainable lifestyle we have created. I have always been an optimist, and devoted my learning and teaching to make people think about all the things that impact them.  I am now resigned to sit back, watch and ponder.  The world will not end, but the uncountable impacts of climate change will alter the lives of every person and all living organisms.

 Now, back to what has always been my main interest and passion...renewable energy vs nuclear power.  I am gratified that I have been on the right side of history leading into the future, since renewable, mainly solar and wind, are making a huge surge in our energy mix.  Despite the continued efforts by the energy powers (fossil fuel and nuclear industries) the growth in clean sustainable energy production surges ahead not only here, but worldwide.  Just in the last few years, the world has become aware of Hydrogen, and its unlimited potential as an energy carrier and storage medium.  A wide range of systems are being developed worldwide using renewables to split water and store that energy in Hydrogen.  All this is in its infancy, but the technology is moving rapidly, as nations move to free themselves from the economic, political, and environmental addiction to fossil fuels. My dream is on its way to becoming a reality.  I can’t really keep up with all the daily developments and technological advances, but the world and its forward thinkers see the economic as well as the carbon-free advantages of Hydrogen as the ultimate energy product eventually replacing coal, oil, and natural gas.  A few recent tidbits of what’s going on are listed below...check them out...pretty exciting.

 Of course, the other hoax (this one is real) is that nuclear power will be the major energy source of the future.  The industry is spending millions and millions of dollars pushing its propaganda that the new generation of nuclear power plants will be cheaper, safer, and carbon-free.  I guess we have to wait another 10 years to see if the first plant that is built will actually work!  The nuclear industry will continue to suck our dollars as their product dies a slow economic death.  Hydrogen will bury them, because it can be made anywhere from renewables and can be developed to scale for local needs, as well as be exported as an economic commodity like oil today to where ever the need is.  The same holds true for another hoax... fusion power.  Even when the fusion reaction is contained, building a very complex and expensive reactor to boil water will never compete with Hydrogen and renewables.

 One last piece of this energy quandary is the infamous electricity grid.  Our centralized system consisted of large power plants producing large amounts of electricity, and distributing it via a massive number of wires to consumers throughout the country.  This allowed for ownership and control of our energy system by a handful of utilities and companies, regulated by a handful of government bodies.  The original idea was to supply cheap and affordable electricity to everyone, regardless of where they lived. This worked pretty well until climate change, the availability of fuel, and the introduction of renewables started to upset the cart.  The grid is old and requires billions of our dollars to be upgraded to meet current and increasing demands.  The energy industry wants so keep its tight control over everything because of the enormous profits generated.  It is threatened by the decentralized model proposed so many years ago…to generate power with whatever local resources are available, and minimize constructing huge power plants.  Renewables and Hydrogen endanger the model.  Examples include the Texas grid now being impacted by the changing climate forces of heat, ice, wind, and flooding.  Here in California, fires are forcing the undergrounding of large transmission lines, and the record heat is currently requiring mandatory blackouts because the grid can’t deliver the necessary electricity.  The system is stressed not because there is too little generation, but there is too much solar electricity available during the day.  The nuclear units at Diablo Canyon cannot be ramped up or down as need be, but must run at full power.  A lot of solar electricity is being wasted!  The PUC has adopted radical new rules limiting how much new solar will be allowed, and who can produce it.  The answer of course is Hydrogen.  Use the excess solar electricity to produce Hydrogen which can be stored and used to produce electricity when needed.  We need to encourage the installation of more solar not only in industrial fields, but on residences, commercial rooftops, and the vast potential lands and spaces in every community.  Solar is not mutually exclusive, and can in many cases improve what goes on beneath them.  California is looking at installing solar over the canals that carry water from the north to the thirsty south, reducing evaporation along the way.

 The narrow thinking of the energy powers is again evident in the current planning for the large offshore windfarm proposed for Humboldt County.  Rather than being innovative and forward thinking (as Humboldt County has usually been) the plan is to spend billions of dollars on a major grid upgrade to ship the electricity 300 miles south where it will then join the main California grid.  What we should be doing is attracting companies to install production facilities for Hydrogen here, where it can be used locally (our power plant is gas fired!) and by the time the wind turbines are incrementally constructed, there will be a wide global demand for Hydrogen which can then be exported as a value-added cash commodity (like our timber products and other valuable resources.)  It is a complex issue, but one needs to follow the politics and money to understand how and why decisions are made.

 Enough!  I could go on and on as to the “value” of renewables and Hydrogen, but I am now content to sit back , enjoy life, and watch the progress made both here and abroad.  In our recent trip to Europe, I saw a Toyota Mirai taxicab…a nice looking ordinary car.  It was a Hydrogen-fuel cell powered vehicle.  Just one tiny use we’ll see in the future!  Meanwhile, let the fusion-power of the sun continue to shine!

 There is so much good news coming out daily on renewables, nuclear, and Hydrogen.  Here is just a sample of a few recent ones.

 

Arizona, of all places.  They do have a lot of sun, and access to all the solar being installed in Mexico.

I Rest My Case

 

I Rest My Case

As Thanksgiving approaches, I am thankful and grateful for so much, especially since in the past several weeks many events have affirmed the two major arguments that I have spent almost my entire life arguing!

The NuScale small modular reactor that was going to pave the way for another “revolution” in the nuclear industry is basically dead. This design, which has never been built or tested, that was supposed to be the savior of our energy needs in the future and solve the CO2 issue, has once again proven that the nuclear industry is a dead dinosaur, still wagging its pathetic tail. The small modular reactor was to be built in Idaho and the electricity transmitted to several utilities in Utah, which just backed out of the deal because the cost has almost doubled from what NuScale said it would be just a few years ago. Just like the “old” large technology, nuclear power is just way too expensive, is still technologically complex and dangerous, and most importantly, the issue of its various nuclear wastes remains unaddressed and kicked down the road for future generations to deal with. Of course, the industry will continue to suck at the trough for our dollars promising that everything will eventually be alright, and the world will eventually build a few of these SMRs, but not the thousands which would be required to make any dent in our energy needs, or because there are no other options. I’ve heard it all for the last 50 years...sorry it’s wrong. The big energy money will continue with this hoax because they make lots of money at...our money!

The other amazing news comes from General Electric, a company that used to build nuclear reactors and is now in the wind turbine business. They have partnered up with Duke Power, one of the largest utilities in the country and in the past a major opponent to renewables They will re-power a natural gas plant in Florida, using electricity from a large solar farm on already on site to produce hydrogen, which will then be stored and used in the reconfigured gas turbines to generate electricity during peak times, and when renewables are not available. How many time have I uttered this concept?!! It is the future, and I am thrilled to see two major corporations finally step up on this path forward. Hydrogen has become the major buzz word throughout the world, replacing the words “friendly atom!”

We’re off to the Bahamas in a few weeks, and I look forward to relaxing and not thinking about our energy future as I have always done! There are so many other things to think and worry about, but I have concluded that there is only so much I can do. About those issues. I am proud and grateful that I have always been on the right path, on the right side of history, and I’ve done what I can. Now, no one has to listen to my rants anymore. The future lies ahead! I rest my case!!!!!!!!!!!!

STATE OF MY HEAD summer 2023

  STATE OF MY HEAD summer 2023

 This past year has been very trying on me, with my hip replacement, sciatica, carpal tunnel, and just plain getting old! I reflect on all the time I spent educating myself on environmental and energy issues so I could teach and educate others as to the importance and complexity that these two factions have on us and the entire global community. I am proud to have been on the “right side of history” in my teaching and my activism, culminating in the final decommissioning of our local nuclear power plant. I wish I could have done more because so much more remains to be done.  I am tired, retired, and passing on those battles to the next generation.  Good luck!!

 Today, we are finally beginning to feel the enormous impacts and consequences of climate change, I agree with James Hansen who said the scientific community failed to be more aggressive in stressing an understanding of the phenomenon and got bogged down in the nitpicky semantics debate...greenhouse effect, global warming, climate change, and now global boiling. The task of explaining the complex environmental, economic, social, technological, and political interactions was overwhelmed by “Big Money” propaganda reducing the threats to a polar bear on an ice floe, or a coastal village on some faraway island being flooded. What wasn’t stressed is that the changes are a continuum and are occurring at an exponential rate. I am distressed that the cares and attitudes of those with the ability to create changes are bogged down by ignorance and money.  So many people worldwide will suffer in so many ways.  Interestingly, money is now becoming a concern with the various insurance industries leading the way.

 I am an optimist in the survival of the environment (we’re not destroying our environment, but changing it) and humanity (civilizations have come and gone due to changes), though I think we have already gone beyond the tipping point, and the chaos we see in the world today will on only continue to escalate. As old sayings go…“Close that barn door…" ”We’ve already fallen off the cliff but…” “Pay attention, Billie Joe!”

As for my work with renewable energy, I am pleased that a lot of what I fought for is slowly coming to fruition, despite the continued resistance by the Big Money (the fossil fuel, nuclear, industrial-military complex, etc.) which has and probably will continue to be a major guiding force in global politics. Solar and wind are now cheap, efficient, and more sustainable than previous technologies. Their potential continues to shine in new directions and applications all over the world.

The next major obstacle to be overcome is the understanding and commercial deployment of Hydrogen technologies. The development of hydrogen technologies throughout the world today is rather stunning, in spite of the ignorance and manipulations of policies here in the US. Europe, China, Australia, India, and Africa are all rapidly moving forward with commercialization because they are real solutions to the enormous problems of fossil fuels. One positive of Putin’s war is the realization that nations don’t have to be dependent on imported oil or gas.

Hydrogen can be produced locally from water (H2O!) for local use or export; it can be made using local renewable energies; it can be combusted in engines, turbines, and furnaces for industry, commercial, and residential uses; or transformed to electricity via fuel cells. It can be used in transportation (ships, airplanes, trucks, fleet vehicles, and maybe eventually in automobiles), and most importantly, it can be created and stored for electricity generation at times when the sun doesn’t shine, the wind doesn’t blow, and there is peak demand which today overwhelms grid capability. It will eventually be cheaper than the price of gasoline which depends on finding oil, extracting it, transporting/importing it, refining it, and even more transportation. It will ease the burden of huge powerlines amplifying electric grids.  It ultimately reduces our dependence and being at the mercy of Big Money politics and their economic shenanigans. The case for the Hydrogen Economy (replacing the OIL Economy) was identified 30+ years ago. The shift is coming, but we’re still battling the power of Big Money wanting the continued path toward a Nuclear Economy. For example, in the US today, the nuclear industry is garnering large portions of the federal hydrogen research money with the promise that the future generation of small reactors will be the "best" way to produce hydrogen fuel.

The nuclear industry continues its hoax that nuclear power is cheap, clean, and necessary. The first of two Vogle plants in Georgia just went online this week…7+? years late, and 2+? Times over budget. Originally estimated at $8-14 billion, the final tab is over $34 billion, and all this just to serve about half a million customers in the local utility. We’ll see if and when the second unit comes online. New big reactors like this are dead, but the industry says it can do better with small modular reactors which are still under development and promise to be cheaper and safer. Of course, this all looks sort of good on paper, but it is still 7+ years before the first one is ever built, tested, and licensed. This will have no impact on our desperate need to produce carbon-free electricity.  In addition, nothing, again, is said about the high-level nuclear wastes that would be generated, to which there is NO solution other than putting them in cans and watching over and maintaining them for thousands of years. Not going to happen, in spite of all the dollars that continue to be spent in R&D and lining executive’s pockets. But wait! The ultimate solution is here…although it may be some 20-30+ years away. FUSION! Major breakthroughs recently towards unlimited, clean, cheap energy! Again, another hoax to funnel billions of dollars toward Big Money. The biggest piece of information missing is that even if constructed, a fusion reactor, would only produce HEAT (not electricity or gasoline or whatever kind of energy we need) just like today’s fission reactors, and require expensive and complex supportive infrastructure. The problem of extracting that heat (the power of the sun right here on Earth!) is technically daunting, and the ultimate cooling water needed is mind-boggling. The fuel necessary is deuterium (one molecule out of every 6,500 molecules of seawater is deuterium). It would be extracted by expensive chemical hydrolysis, with a waste product of hydrogen atoms! Gee! I thought simple electrolysis of water was too expensive and too difficult. ?? China now has a pilot plant that electrolyzes plain seawater.

The dream of a green, sustainable, renewable, and equitable energy future is slowly edging towards reality. Just like climate change, the transition is not immediate, but an evolution of ideas, technology, commercialization, and most important, political will. I remain an optimist. For now, I am content to sit back and look at what is going on in the world with a full range of emotions…joy, frustration, but also a lot of humor. It is what it is, and I’ve done what I can.

 Let the sun shine and the wind blow!

A March Energy Update

 Here it is, the beginning of March, and I am celebrating my new hip with a great trip to the Bahamas, where I plan on doing a lot of walking on the pink sand beach, and a lot of fun reading and relaxing.  As I’ve said before, I am stepping away from my activism and constant following and reading about what is going on in energy and climate.  I have achieved two major goals I worked hard for, namely decommissioning the Humboldt Bay nuclear power plant, and excited to see the real beginning of a hydrogen economy.  But my mind and heart still long to keep up with what is going on, but at a slower pace.

The nuclear industry continues to use its power and money (mostly our money) to keep the current reactors limping along, and promising the new phase of reactors will be important energy producers in the future.  These fission power plants have not been built or tested yet, and are years away from having any kind of impact on our energy supply, except sucking up lots of money, which could be used for more beneficial purposes.  The industry pushes for some kind of disposal and management of nuclear wastes which will result in moving casks from here to there forever since there is no solution other than cask storage and long-term monitoring.  There are over 80 nukes that eventually will need to be decommissioned and their huge mass of low-level waste dealt with.  Cleaning up the rest of the nuclear infrastructure will drain away much-needed dollars.  And on top of this, the recent hysteria over fusion power keeps the myth of unlimited energy alive.  Fusion will allow us to extract deuterium from seawater, and fuse it to produce huge amounts of heat.  The infrastructure for using this heat is as mired and complex as fissioning uranium.  By the time this is even possible, we will have transitioned to renewables and hydrogen.  We already have a fusion reactor 93 million miles away, and do not need to create one here on earth.  So much is not mentioned or misstated.  Deuterium is extracted by electrolysis of seawater. There is one deuterium atom for every 6,500 normal hydrogen atoms.  The heavier deuterium is further separated sort of like uranium enrichment.  What to do with the depleted hydrogen?!!!   The whole fusion cycle is a very complex technology, requiring tritium (produced in fission reactors), producing neutron-activated radioactive wastes, and a mindboggling amount of heat.  It ain’t gonna happen…at least for a long while.

Meanwhile, hydrogen production and its deployment is increasing at an amazing exponential rate.  Thanks to Putin, green hydrogen has finally taken the world stage as the unlimited, non-carbon, sustainable, equitable, multipurpose, and eventually inexpensive fuel for the future.  It’s been 30+ years in the making but is now beginning to come to fruition augmenting and replacing natural gas, fuel for all modes of transportation, and the advantage of being produced from renewables almost anywhere, and transportable to markets everywhere.  The transition is in full swing all over the world (not so much here in the US where the fossil fuel and nuclear industries continue their stranglehold on our energy supply.)  Of course, this will take time, but the technology and infrastructure will mature very quickly.  More on all this later!!

 

With climate change, what can I say?!!!   Changes and impacts predicted 30-40 years ago are now occurring at increasing rates.  This past year…all over the globe…but just here in the US and California

We have seen record weather phenomena…hurricanes, flooding, tornadoes, fires, droughts, cold, snow, etc.  The human and economic burden is also increasing, and it ain’t over… the changes will continue to escalate over the years, even if we somehow limit CO2. Not much more I can say, other than preparing the best way we can for the future.  But the sun still shines, the winds do blow, and with a new hip, life is good!

LOOKING FORWARD TO 2023

 

As I look forward to another new year, I’m reflecting back on what I have accomplished not only in the past year but in my 60+ years advocating for a clean sustainable environment.  There have been so many battles confronting an enormous range of ignorance, greed, and stupidity, but in the end, I feel I have achieved a lot of what I struggled to do.  I have continued to learn so much and have always pushed to educate and inform a great variety of people. My main goal over the past 30+ years has been to increase awareness that Hydrogen is the key element in our renewable energy future, and that nuclear power is ethically, morally, and economically wrong.

I have reached a point where I no longer have to fight for the acceptance of many of my ideas, so for now I am going to step back a bit from my manic and frenzied daily reading and research, and trying to keep up with what is going on around the world right now.  Mainly, I am overwhelmed by the exponential amounts of information forthcoming on the development and commercialization of Hydrogen all over the world, which is still in its infancy, and the growth of renewables in all sectors of our economy.  So here are a few predictions for the future that I stand by, and probably comment on in the future.

Hydrogen will eventually surpass fossil fuels as the major energy carrier, in all aspects of our technology and economy.  The majority of Hydrogen will be “green” and come from a variety of renewable energy technologies. Other technologies will also play an appropriate role.

Nuclear power will continue its amazing hoax, sucking up billions of dollars for the development and supposed deployment of a wide range of reactors, which will not compete in the Hydrogen economy.  Fusion is now the latest buzz, and though we may eventually build a fusion power plant, its infrastructure cost will be untenable. What people don’t realize is that a fusion reactor does not create electricity.  The tremendous amount of heat produced will be used to boil water for steam-turbine generation.  Again, it’s like using a chainsaw to cut butter.  There is a lot of money to be made in this hugely complex and inappropriate technology, and it plays on the ignorant fact that it promises a simple solution to our energy problems.  People are ignorant and gullible and want to hear that.

Solar energy will continue to mature on many fronts, and new developments and improvements will provide us with a cleaner, affordable, and sustainable energy future.  The biggest issue is not producing enough electricity, but relying on a massive antiquated grid to move that electricity to where it is needed. Microgrids and minigrids will blossom, offering more use of local renewables and a range of storage options that are cheaper and environmentally sensitive.

With climate change now visibly upon us, we will be forced to take more serious actions to slow down its mind-boggling impacts.  The changes we see today will only continue and will get worse.  Water quality will be one of the next major challenges, as well as food production, social injustice, migration, massive infrastructure repair and upgrade, and a degrading of the quality of life for many.

The escalating cost of paying for the damages from climate change, and preparing for the necessary improvements and protections for our infrastructure will only compound all issues. Greed, inequality, power plays, wars, lies and misinformation, and basically what I’ve said all along, ignorance and stupidity, do not portray a very optimistic future.  I have talked with a lot of people, some of who I consider to be intelligent and in position to understand what is really going on, who have in general disappointed me with their ignorance, shallowness, and apathy.  The world and its issues are so complex that it is easy to just let “them…the experts” take care of things. 

So, I am stepping down a bit from trying to change the world, and do what I can in my community; but I pass the torch on to the younger generation and hope they will take positive and sane actions.  We are not doomed; we are not destroying the environment; but the changes we have created will continue to threaten all aspects of civilization as we know it today.  Does the butterfly in the Amazon (forest) really have any impact on the migration of millions of refugees?

I am grateful for who I am and for all the things I have done.  This may be my last blog for a while (I know that sounds easy) and I will continue to play the fiddle while the world burns (much harder), and acknowledge that my life’s work has been on the right side of history.

Happy New Year!!!!

KCLU podcast on HB and Diablo Canyon Decommissioning

 


How Diablo Canyon’s likely delayed decommissioning will be extremely costly and comes with risks

KCLU | By Michelle Loxton

Published November 25, 2022 at 12:00 AM PST


California's last operational nuclear power plant is perched on the ocean’s edge near the City of San Luis Obispo on the Central Coast. Diablo Canyon was due to close in 2025 – it’s unlikely that’s going to happenBut, ultimately one day it will be decommissioned. We look at the costs and risks for the local community.

The story comes from KCLU’s podcast The One Oh One. You can listen to the full episode here.

California’s largest single source of electricity, about 10% of it, comes from Diablo Canyon Nuclear Power Plant. And that electricity is carbon free.

This plant sits on the edge of the Pacific Ocean, west of San Luis Obispo and south of Morro Bay.

A lot of power plants loom large in the communities they reside – this one – not so much. The plant is miles from the closest community and perhaps the only reason you’d be traveling in that direction is to hike the beautiful nature trails of the state park that neighbors the plant.

“Diablo Canyon’s tucked away seven miles down a road, out of sight to a large number of people out of mind,” said Bruce Gibson, the current Chair of the San Luis Obispo County Board of Supervisors. He’s been a supervisor since 2007.

“My guess is that 85 to 90% of the population hardly ever think of it,” said Gibson.

It’s not on the radar of many people – even the locals.

So why should we care about this plant?

Even if it's not going to happen on its original schedule, Diablo Canyon will eventually be decommissioned.

And, that decommissioning process will not be quick. It could take decades; cost billions of dollars; with the end product possibly being a hundred plus canisters of spent nuclear waste stored at the site in perpetuity.

That impacts San Luis Obispo County and its residents of course, but the cost and risks to decommissioning should be something we all pay attention to.

We need a case study

To fully understand what this process will be like, it helps to have a case study of sorts.

Luckily there is something like that – the now decommissioned Humboldt Bay Nuclear Power Plant, located over 500 miles north of Diablo Canyon, also on the California coast.

Mike Manetas

/

After operating for only 13 years, Humboldt Bay Nuclear Power Plant went offline in 1976, after the discovery of an earthquake fault below it. From the moment it went offline to the end of the decommissioning, the process took 45 years.

“I've been here since 1966 and I've been living in the same place for the last 50 years actually,” said Mike Manetas, a longtime Humboldt Bay resident and a retired professor from Humboldt Bay State University, now known as Cal Poly Humboldt.

As part of the Environmental Engineering Department for over 20 years he taught a class on the decommissioning of the Humboldt Bay Nuclear Power Plant and was appointed to the community advisory board following that decommissioning – which meant many trips to the plant over the years.

“Because nobody knew anything about what was going on. And so I learned a lot myself. And I brought in all kinds of expertise to examine what the process was,” said Manetas.

Why is Humboldt Bay a good case study for us to use? 

Well, firstly that decommissioning has been completed. The whole process is done. It’s also – like Diablo Canyon – right on the ocean’s edge with some of the same concerns like earthquake faults and marine impacts. And lastly, they’re both operated by Pacific Gas and Electric or PG&E.

A note here: despite multiple requests to PG&E for an interview for this episode, I never heard back.

So by studying Humboldt Bay’s decommissioning we can get an idea of what to expect.

With everyone I spoke to for this story, the two most important factors about decommissioning came down to the costs and the risks.

Let’s start with the costs.

After operating for only 13 years, Humboldt Bay Nuclear Power Plant went offline in 1976, after the discovery of an earthquake fault below it.

“Everything in the facility is to be removed and the site will be restored back to what it naturally was before the plant was built there,” explained Manetas.

So it went offline in the mid-1970s. Actual decommissioning only started in 2009. The site was completely decommissioned last year – 2021 – meaning from the moment it went offline to the end of the decommissioning, the process took 45 years.

Manetas kept a tab on the money being spent to decommission.

“The cost of decommissioning is something that's enormous and it's really incalculable,” said Mike Manetas.

The total projected cost was originally put at $95 million, he says, but ended up being just over a billion dollars.

Before decommissioning began – 1976 to 2008 – Manetas estimates another half a billion dollars was spent caretaking the plant after it went offline.

And the costs aren’t over. There are six casks on the site today – these are huge canisters of the spent high-level nuclear waste left over after decommissioning. They have to be kept safe and that costs money.

“The PUC, the Public Utilities Commission, has authorized PG&E to collect $150 million to safeguard that waste to the year 2035,” said Manetas.

And those canisters could be there for a very, very long time. There’s been talk for years about a federal site for high-level nuclear waste – spent fuel – but that hasn’t happened yet so like many sites across the U.S., Humboldt Bay is stuck with its nuclear waste.

And that waste stays highly radioactive for thousands of years.

“The waste that literally is going to stay with us in the environment for 10,000 years,” said Manetas.

He says they have been told these storage vessels are sufficient for up to 80 years.

“The industry says originally they told us, ‘Oh, it's good for 40 years’ now they're saying, ‘Oh, they're good for 60 years’, gee, maybe 80 years,” said Manetas. “Okay, that's beside the point. The point is, is that at the end of 80 years or 60 years or 40 years, what happens to these casks? They're going to degrade.”

So they have to keep an eye on what to do with the aging canisters storing waste that lasts for thousands of years.

The safe storage of the waste adds up to a lot of money for taxpayers for a plant that ran for just over a decade a long time ago.

“The analogy I use is you buy an automobile, you buy a Cadillac, and ten years later, it's run its course and you either sell it or take it to the junkyard,” said Manetas. “And then for the rest of your life, you're going to get a bill, $1 or $2 a month, because you owned that Cadillac to take care of the muffler that is highly radioactive and has to be watched over for 10,000 years. I mean, it's mind boggling.”

Ok, so those are the mind-boggling costs, as Manetas puts it.

In our case study let’s move onto risks.

During decommissioning there are risks to dismantling a plant – you know, the actual buildings and everything in it.

“They have to go in and very carefully remove that either robotically or with people with suits,” said Manetas.

As a member of the community advisory board following the decommissioning of Humboldt Bay Nuclear Power Plant, Mike Manetas was able to visit the site many times and take photographs. He says divers had to scrape the walls of the spent fuel pool as part of the process. These are the suits they would wear.

16,000 truckloads of the low-level waste from reactor operations were transported offsite, Manetas says.

“It's a very, very expensive, difficult technology to take this stuff apart and then to package it and then to ship it someplace wherever it's going to go,” said Manetas.

Then there are the environmental and external risks. What happens if there’s an earthquake or tsunami – think Fukushima in Japan. What about war – Europe's largest nuclear plant – Zaporizhzhia – wasn’t on many people’s radar until Russia invaded Ukraine.

And then there’s the more likely and imminent threat to the Humboldt Bay site specifically – sea level rise.

Jennifer Marlow is the assistant professor of Environmental Law at Cal Poly Humboldt.

“The bluff upon which the spent nuclear fuel at Humboldt Bay is stored – it's 115 feet away from the shoreline and 44 feet above sea level. And so it used to be 96 feet about high and now it's 44 feet high,” said Marlow. “And so it's a particularly erosive part of Humboldt Bay. Over time, as erosion accelerates, as sea level rises, and as that seawall currently protecting the bluff might be breached.”

Marlow explains what this means for the rip rap retainer wall, also known as a seawall, currently protecting the site and shoreline.

“With 1.5 meters of sea level rise, there would be chronic or monthly overtopping of that rip rap wall,” said Marlow. “And with 2 meters of sea level rise, that rip rap wall would be overtopped daily at high tide, and it would make the spent nuclear fuel site, an island with everything around it submerged by the rising sea.”

And image taken in 2020 of the seawall close to the Humboldt Bay Nuclear Power Plant site. Researchers have looked into how sea level rise could overtop that seawall and affect the site storing leftover high-level nuclear waste.

Marlow said credible tsunami risks have also been looked into, and reports suggest the maximum tsunami run up level is 43 feet – dangerously close to where the site sits currently at 44 feet.

“What we don't know is how sea level rise is going to impact this tsunami run up estimates into the future,” said Marlow.

So how does this all compare to Diablo Canyon? 

Of course, we can’t do a complete apples to apples comparison, but we can make some educated assumptions.

Let’s first look at the size and lifespan of the plants for comparison and what that means for the leftover nuclear waste.

Humboldt Bay was a 65-megawatt nuclear power plant. Diablo Canyon is over 30 times bigger at over 2,000 megawatts.

Humboldt Bay operated for 13 years. Diablo Canyon has been operating for 37.

Essentially this all means a lot more nuclear waste. Far more than the six canisters at Humboldt Bay. Mike Manetas has done some math and he puts the eventual number at Diablo Canyon at around 300 canisters.

I put this eye-popping number to another one of my sources – David Weisman, the legislative director for the Alliance for Nuclear Responsibility.

The alliance opposes nuclear power because it says it’s too expensive and cumbersome for what it delivers. It has been actively involved in the decommissioning plans.

So, how many nuclear waste canisters would be stored on the site after decommissioning? Weisman lives in Morro Bay, just north of Diablo Canyon.

His estimate is a lot less than Manetas’ 300.

“My number was like 138. In other words, if the plant runs to the end of its life, that has planned – 2025, they have 70 up there now and they’ve ordered another 68, 70 from this new vendor,” said Weisman.

Either way, it’s a huge number compared to Humboldt Bay. A lot more highly radioactive waste to keep an eye on and store safely for those thousands of years.

“The biggest question we would have also of the longevity of the canisters is – it's the marine environment. It may not be immediately impacted by tsunami or erosion. But you've got the fog, the cold air, the mist. And they're absolutely going to have to maintain a vigilant program to make sure that rust and corrosion…”

… Doesn’t affect the canisters.

And Diablo Canyon, because of its size and how long it's been operating, has a ton of that low-level waste as well.

“All the toxics involved in the building have to be carefully wrapped and transported away,” said Weisman.

Weisman says at first the plan was to transport thousands of loads of this waste off site by truck – like they did at Humboldt Bay.

“Avila Valley roads, a little winding road that leads from the plant. There were going to be thousands of truckloads and the local people are like, ‘What?’ So a decision was made for most of the bulky stuff – we're going to build a dock where the intake is, load it on a barge and send it down to Port Hueneme or something like that,” said Weisman.

Low-level waste on barges or trucks – all of this, as with the theme of this piece, has risks and costs a lot of money.

Let’s now turn to environmental and external factors. Weisman has already pointed to one of them – marine impacts. Let’s look at some others.

Sea Level rise is not as much of a concern for Diablo Canyon as in Humboldt Bay, Weisman says. The canisters are stored up the hill 200 feet above sea level.

What about earthquakes? Well PG&E has long maintained that the plant could withstand an earthquake. But the plant is located close to several earthquake faults and many locals have voiced concern about its safety for decades.

One of the main factors in the original plans to shut down Diablo Canyon was the high cost of retrofitting it to meet updated environmental regulations.

Talking about money. Let's look at the total cost of decommissioning. In 2021, the California Public Utilities Commission approved an estimated $3.9 billion needed to safely decommission the plant.

But remember our professor from Humboldt Bay – Mike Manetas – and how he kept an accounting of that decommissioning. He believes the costs will go up.

“Diablo Canyon right now they're saying, ‘Oh, we're going to do it for $4 billion’. Well, if you look 30 years down the road, that $4 billion could easily become $10 billion. $20 billion,” said Mike Manetas.

And finally let’s turn to the timeline.

Compared to Humboldt it seems decommissioning at Diablo Canyon, when it does actually start, will be a lot quicker.

PG&E has details on their website about their plans for decommissioning – on its page dedicated to the process, it says, after the plant is shut down… “Decommissioning will begin promptly and the process will take approximately ten years.”

David Weisman and I discussed what this would look like if shutdown plans were still going ahead on the original timeline

David Weisman: In theory, by about 2035 the soil would be flat. The domes in the structures are gone. They’d regrade the hillside planted with native vegetation. And so by the mid to late 2030s, it should have looked like nothing had ever been there.  

Michelle Loxton: Except for the waste that's sitting in the canisters?  

David Weisman: Two football fields or three football fields up on the hill. But again, the benefit is the entire security perimeter shrinks to just that area. That opens up the land, which is what the REACH people and these others were looking at, or the native tribes and indigenous tribes are now looking at it as well. 

The REACH people Weisman is referring to there, is a regional economic group that has put forward a plan to turn the fully decommissioned site into a Clean Energy Innovation Tech Park with desalination, battery storage, wind energy and a community center. This was a plan that many local political leaders and community groups had signed on to.

What it all means for San Luis Obispo County

I wanted to end this piece with the reason why I decided to tell the story of Diablo Canyon in the first place – why we should care.

Beyond the cost to rate and taxpayers across the state, the risks associated with having a nuclear power plant and its left-over waste nearby, is mostly on the local community.

California’s largest single source of electricity, about 10% of it, comes from Diablo Canyon Nuclear Power Plant. This plant sits on the edge of the Pacific Ocean, west of San Luis Obispo and south of Morro Bay.

Bringing Bruce Gibson back in here, the San Luis Obispo County Supervisor.

“The risk of those things, the impact of an accident, a bad outcome, and any of those issues rests physically on San Luis Obispo County,” said Gibson.

Gibson has a background in geophysics and has been involved in monitoring Diablo Canyon’s operations for many years.

“Diablo Canyon has been a big deal in San Luis Obispo County for a very long time, and there's a great diversity of view about it,” said Gibson. “There are those who have long objected to its construction and its operation, and there are those who are extremely supportive of it because of its impact on our economy. It is easily the single largest private employer in our county and has provided a great number of well-paying head of household jobs.”

Despite the polarizing local opinions about the plant, he says he understands why it needs to stay open a little longer.

“I am comfortable with its operation. And I certainly understand the case to be made that extending its life for a certain amount of time in the time we are transitioning to renewable energy could provide some benefits to the entire state of California,” said Gibson.

He says he tries to stay neutral when representing the overall interests of his community.

“I see my job as holding PG&E and the other regulatory bodies accountable for doing the best possible job of mitigating those impacts,” said Gibson. “There's the risk of an accident while the plant’s operating – that's obviously very much top of everybody's mind. But more than that, there's the issue, for instance, of the spent fuel that's still stored on that site. And so far as we can see, it is going to be there for the rest of my life.”

“I can't be one of those folks that just lets it go. I have to be thinking about it,” said Bruce Gibson.

I asked him about how he approaches an issue that will remain relevant far beyond the lifespan of his political career.

“But that whole business of burdening generations for 10,000 years to take care of something that cannot escape into the environment is a huge ethical question. So we benefited from this. And ‘Hey, kids, here's your legacy’. Right? We talk all the time about the programs we have to put in place for that are much longer than terms in office,” said Gibson.

For Gibson, in the end it all comes down to never being able to disengage from what is happening at Diablo Canyon.

“I can't be one of those folks that just lets it go. I have to be thinking about it,” Gibson said. “Never lose sight of its benefit and risk… I think we can get successfully to the next phase. And I'm certainly hopeful for that.”
