Earthquake risks and rising costs: The price of operating California's last nuclear plant
Under two gargantuan domes of thick concrete and steel that rise along California’s rugged Central Coast, subatomic particles slam into uranium, triggering one of the most energetic reactions on Earth.
Amid coastal bluffs speckled with brush and buckwheat, Diablo Canyon Nuclear Power Plant uses this energy to spin two massive copper coils at a blistering 30 revolutions per second. In 2022, these generators — about the size of school buses — produced 6% of Californians’ power and 11% of their non-fossil energy.
Yet it comes at almost double the cost of other low-carbon energy sources and, according to the federal agency that oversees the plant, carries a roughly 1 in 25,000 chance of suffering a Chernobyl-style nuclear meltdown before its scheduled decommissioning in just five years — due primarily to nearby fault lines.

As Gov. Gavin Newsom’s administration looks to the aging reactor to help ease the state’s transition to renewable energy, Diablo Canyon is drawing renewed criticism from those who say the facility is too expensive and too dangerous to continue operating.
Diablo is just the latest in a series of plants built in the atomic frenzy of the 1970s and ’80s seeking an operating license renewal from the federal Nuclear Regulatory Commission as the clock on their initial 40-year run ticks down. As the price of wind and solar continues to drop, the criticisms against Diablo reflect a nationwide debate.

The core of the debate lives in the quaint coastal town of San Luis Obispo, just 12 miles inland from the concrete domes, where residents expected Diablo Canyon to shut down over the next year after its license expired.
Instead, Newsom struck a deal on the last possible day of the state’s 2021-22 legislative session to keep the plant running until 2030, citing worries over summer blackouts as the state transitions to clean energy. The activists who had negotiated the shutdown with PG&E and the state six years prior were left stunned.
Today, the plant is still buzzing with life: Nuclear fission, in the deep heart of the plant, continues to superheat water to 600 degrees at 150 times atmospheric pressure. Generators continue to whir with a haunting and deafening hum that reverberates throughout the massive turbine deck.
Left untouched, nuclear fission erupts into a runaway chain reaction that can heat the core of a nuclear plant to thousands of degrees, liquifying the metal around it into radioactive lava.
So, operators have to constantly stifle the reaction to keep it under control.
In the event of an earthquake, they need to stop the reaction as quickly as possible. But if the shaking is so rapid and intense that the plant is critically damaged before it can shut down, operators could become helpless in preventing a meltdown.

Diablo Canyon is built to endure specific intensities and speeds of shaking — but predicting how likely an earthquake is to exceed those specifications is no easy task. Earthquakes are the result of deeply complex underground motion and forces, and they’re notoriously chaotic.
In order to start estimating the seismic safety of the plant, geophysicists have to understand: first, where the faults are; second, how much they’re slipping to trigger earthquakes; and finally, when those quakes hit, how much shaking they cause.
Earthquakes account for about 65% of the risk for a worst-case scenario meltdown. Potential internal fires at the plant make up another 18%. The last 17% is made up of everything from aircraft impacts and meteorites to sink holes and snow.
In assessing the likelihood of all these threats, the Nuclear Regulatory Commission estimates that in any given year, each of Diablo Canyon’s two reactor units has a roughly 1 in 12,000 chance of experiencing a nuclear meltdown similar to Japan’s Fukushima disaster.
Likewise, there’s about a 1 in 127,000 chance a failure will cause the plant to release exorbitant amounts radioactive material into the atmosphere before residents could evacuate, creating a Chernobyl-style disaster.
This means that, every year, nearby residents have roughly the same chance of seeing a nuclear meltdown as dying in a car crash. Also, in any given year, they’re about 50 times more likely to face a mass-casualty radioactive catastrophe than get struck by lightning.
Diablo Canyon employees work around the clock to ensure the risk is as small as possible. “Our safety culture, it’s always on the top of my mind,” said Maureen Zawalick, the vice president of business and technical services at Diablo. “It’s in my DNA.”

The plant is the only one in the U.S. with a dedicated geoscience team that studies the region’s seismic landscape. And like other nuclear facilities, Diablo has done countless tests on its equipment, hosted walkthroughs with regulators to identify possible points of failure and generated thousands of pages of analysis on the facility’s ability to withstand the largest earthquake possible at the site.
Earthquake precautions include massive metal dampers that are fixed to essential infrastructure, such as the duct carrying the control rooms’ air supply. In the event of a tremor, monstrous concrete pillars penetrate deep into the bedrock to keep the building and essential infrastructure grounded. The hefty concrete walls reinforced with steel rebar as thick as a human arm safely distribute the forces throughout the structure to prevent critical cracks or collapses.
If the plant loses power, there are backup generators for the backup generators.

Operators spend a fifth of their time on the job training for every possible nightmare. Diablo has a simulator on site that’s an exact replica of the Unit One control room. It’s capable of putting operators through the worst conditions imaginable. It shakes with the vigor of a real earthquake. The lights flicker and the analog dials spin back up as emergency power comes online.
For everyone working on site — including the senior leadership team — safety is personal. Should something go wrong, their lives are on the line.
“With any source of energy, there is risk,” said Zawalick. “All the independent assessments, all the audits, all the third party reviews, all of that …. is what gives me the confidence and the security and the safety of why I’ve been out here almost 30 years.” Her office is no more than 500 feet from the reactors.
“If there ever was an earthquake of any magnitude in this community,” she said, “I would grab my two daughters and we’d come here.”

Many critics charge that the risks are understated — due in part to a cozy relationship between industry and regulators. (Some scientists involved with one of Diablo Canyon’s two independent review organizations have collaborated on scientific papers with PG&E staff and funding.)
The Nuclear Regulatory Commission also oversees the plant and conducts its own investigations. In July, the government agency dismissed all three formal criticisms against Diablo’s seismic safety in the plant’s license renewal process.
Sam Blakeslee, a San Luis Opispo geophysicist and former state senator and Assembly member, has a list of technical concerns — primarily the lack of shaking data close to fault lines, which are used to inform the models that predict earthquake motion at the plant — but he likens the core of his concern to the NASA Challenger disaster.
NASA publicly touted a strong safety culture and low chances of things going wrong. Yet, the investigation found political and public pressures had corrupted the safety from the top down.
He argues this is a possibility for any large organization dealing with complex and potentially dangerous systems. Therefore, people need to constantly hold the plant accountable.
“That’s why I tend to try to make sure that the community voice is present,” he said, “ because we are the ones that will pay the price.”
In 2022, Newsom introduced a proposal to keep Diablo Canyon open past its two reactors’ 2024 and 2025 shutdown dates. His proposal, distributed to lawmakers just three weeks before the end of the legislative session, set off a flurry of negotiations among PG&E, the governor and the Legislature.
After discussion drew on past midnight, the Legislature passed the bill.
But it comes at a cost.
While the average price of solar and wind have dropped dramatically over the past 15 years, nuclear’s has been steadily rising. In 2009, solar cost three times what nuclear did, and wind was about even with it. Now, nuclear is over two times the cost of both renewables.
Technical advancements have slashed the price of renewable energy, but nuclear power has faced more outages, equipment replacements and increasingly stringent and expensive safety requirements in the wake of the Fukushima disaster.
One study from MIT researchers found that about a third of the increasing cost could be attributed to safety requirements from the Nuclear Regulatory Commission. They attribute another third to research and development projects for efficiency, reliability and safety improvements, and they assign the final third to a decrease in worker productivity — perhaps in part due to lower morale.

PG&E is estimating that Diablo Canyon will produce energy at $91 per megawatt-hour during its extension. (The average U.S. household buys about 10 megawatt-hours every year.)
However, the Alliance for Nuclear Responsibility argues the plant’s cost is even higher. David Weisman, the legislative director at the alliance, said PG&E is using optimistic predictions of its energy output for the extended period — 5% higher than previous years.
On top of that, the state gave PG&E a $1.4-billion loan to alleviate the initial costs of extended operations. But Wiesman said the funds don’t necessarily need to go toward offsetting the cost of running Diablo. The federal government agreed to reimburse the state up to $1.1 billion — depending on whether the plant meets specific operating criteria — and PG&E is expected to pay off the rest of the loan with profits.
While the loan isn’t a cost that consumers would see on their energy bills, taxpayers across the country could foot the bill. Weisman argued that it brings Diablo’s cost to a maximum of $115 per megawatt-hour — roughly double the cost of solar.
Yet Newsom argues that if California is to meet its goals of 60% renewable energy by 2030, Diablo needs to stay online in the meantime to ensure the state has reliable power amid heatwaves and wildfires.
Diablo Canyon essentially runs 24/7, providing constant power to the state (assuming it doesn’t have any issues, which it sometimes does). For solar to provide similarly constant power, the electric grid will require a massive expansion of its battery infrastructure to store the energy between the midday peak of energy production and the evening peak of energy use.
However, new studies are finding that energy storage is a feasible approach to grid reliability — and that even when adding the price of that infrastructure, solar still costs less than nuclear.

Since Diablo’s extension was signed into law, California has almost doubled its battery storage. The state now has enough to supplement about a quarter of the state’s power needs for about half an hour during peak energy usage (although, in practice, it would likely supplement much less for much longer).
“That’s four or five Diablo Canyons,” said Weisman. Newsom should “save the people of California [billions of dollars] thrown down PG&E’s rat hole, declare triumphant victory in the renewable race and accept the laurels.”
Instead, at a recent press event announcing California had reached a fifth of its storage capacity goal, Newsom laughed off the idea that Californians will no longer have to worry about blackouts.
“We have a lot of work to do still in moving this transition, with the kind of stability that’s required,” he said. “So no, this is not today announcing that blackouts are part of our past.”
Diablo Canyon’s leaders and advocates view the plant as supporting California through this challenging transition period: It’s not perfect, but it provides the state with much-needed reliable, clean power, they say.
In a conference call shortly after Diablo’s initial 2024 shutdown date was negotiated, then-chief executive of PG&E Tony Earley acknowledged the plant would eventually become too expensive to operate.
“As we make this transition, Diablo Canyon’s full output will no longer be required,” he said.

Zawalick said the Diablo team is ready to continue operating as long as the state needs it to. “Thinking about electrification, [electric vehicle] demand, continued drought, the temperatures we’re seeing, wildfires … tariffs — I mean, the list goes on,” she said. “That’s making the equation a bit challenging to see exactly when Diablo will shut down versus how long Diablo will be needed by the state.”
You don’t have to live close to a wildfire to be affected by its smoke. With severe winds fanning the fires in and around Pacific Palisades, the Pasadena foothills and Simi Valley, huge swaths of the Southland are contending with dangerous air quality.
Wildfire smoke can irritate your eyes, nose, throat and lungs. The soot may contain all kinds of dangerous pollutants, including some that may cause cancer. The tiniest particles in smoke can travel deep into your lungs or even enter your bloodstream.
Conditions like these aren’t good for anyone, but they’re particularly bad for people in vulnerable groups, including children, those with asthma or other respiratory conditions, people with heart disease and those who are pregnant.
Here’s what you should know to keep yourself safe.
Stay indoors
Minimize your exposure to unhealthy air by staying inside and keeping your doors and windows shut.
If you have a central heating and air conditioning system, you can keep your indoor air clean by turning it on and keeping it running. Make sure the fresh-air intake is closed so that you’re not drawing in outdoor air.
Keep your pets inside
They shouldn’t breathe the unhealthy air either.
Check your air filters
Clean filters work better than dirty ones, and high-efficiency filters work better than regular ones. The California Air Resources Board and the South Coast Air Quality Management District recommend filters with a MERV rating of 13 or higher.
You might consider using portable high-efficiency air cleaner in a room where you spend the most time. The U.S. Environmental Protection Agency has information about them here, and CARB has a list of certified cleaning devices here.
Don’t pollute your indoor air
That means no burning candles or incense. If your power is out and you need to see in the dark, you’re much better off with a flashlight or headlamp.
If you’re cold, bundle up. This is not the time to start a cozy fire in the fireplace. Don’t use a gas stove or wood-fired appliances, since these will make your indoor air quality worse, not better, the AQMD says.
The CDC also advises against vacuuming, since it can stir up dust and release fine particles into the air.
Take care when cleaning up
You don’t want your skin to come into contact with wildfire ash. That means you should wear long sleeves, pants, gloves, socks and shoes. The AQMD even wants you to wear goggles.
If you’re sweeping up ash outdoors, get a hose and mist it with water first. That will keep it from flying up in the air as you move it around. Once the ash is wet, sweep it up gently with a broom or mop. Bag it up in a plastic bag and throw it away.
It’s a good idea to wash your vehicles and outdoor toys if they’re covered in ash. Try not to send ashy water into storm drains. Direct the dirty water into ground areas instead, the AQMD advises.
Those with lung or heart problems should avoid clean-up activities.
Discard spoiled food…
If you lost power for a significant length of time, the food in your refrigerator or freezer may be spoiled.
Food kept in a fridge should stay safe for up to four hours if you’ve kept the door closed. If you’ve been without power for longer than that, you’ll need to toss all perishable items, including meat, poultry, fish, eggs, milk and cut fruits and vegetables. Anything with “an unusual smell, color, or texture” should be thrown out as well, according to the U.S. Centers for Disease and Control Prevention.
Refrigerated medicines should be OK unless the power was out for more than a day. Check the label to make sure.
…even if it was in the freezer
Your freezer may be in better shape, especially if it’s well-stocked. Items in a full freezer may be safe for up to 48 hours if it’s been kept shut, and a half-full freezer may be OK for up to 24 hours. (The frozen items help keep each other cold, so the more the better.)
If items have remained below 40 degrees Fahrenheit (4 degrees Celsius) or you can still see ice crystals in them, they may be OK to use or refreeze, according to the federal government’s food safety website.
Ice cream and frozen yogurt should be thrown out if the power goes out for any amount of time. Meat, poultry, seafood, eggs, milk and most other dairy products need to go if they were exposed to temperatures above 40 degrees F for two hours or longer. The same goes for frozen meals, casseroles, soups, stews and cakes, pies and pastries with custard or cheese fillings.
Fruit and fruit juices that have started to thaw can be refrozen unless they’ve started to get moldy, slimy or smell like yeast. Vegetables and vegetable juices should be discarded if they’ve been above 40 degrees F for six hours or more, even if they look and smell fine.
Breakfast items like waffles and bagels can be refrozen, as can breads, rolls, muffins and other baked goods without custard fillings.
Consider alternative shelter
If you’ve done everything you can but your eyes are still watering, you can’t stop coughing, or you just don’t feel well, seek alternative shelter where the air quality is better.
Hold off on vigorous exercise
Doing anything that would cause you to breathe in more deeply is a bad idea right now.
Mask up outdoors
If you need to be outside for an extended time, be sure to wear a high-quality mask. A surgical mask or cloth mask won’t cut it — health authorities agree that you should reach for an N95 or P-100 respirator with a tight seal.
Are young children at greater risk of wildfire smoke?
Very young children are especially vulnerable to the effects of wildfire smoke because their lungs are still rapidly developing. And because they breathe much faster than adults, they are taking in more toxic particulate matter relative to their tiny bodies, which can trigger inflammation, coughing and wheezing.
Any kind of air pollution can be dangerous to young children, but wildfire smoke is about 10 times as toxic for children compared to air pollution from burning fossil fuels, said Dr. Lisa Patel, clinical associate professor of pediatrics at Stanford Children’s Health. Young children with preexisting respiratory problems like asthma are at even greater risk.
Patel advises parents to keep their young children indoors as much as possible, create a safe room in their home with an air purifier, and try to avoid using gas stoves to avoid polluting the indoor air.
Children over the age of 2 should also wear a well-fitting KN95 mask if they will be outdoors for a long period of time. Infants and toddlers younger than that don’t need to mask up because it can be a suffocation risk, Patel said.
What are the risks for pregnant people?
Pregnant people should also take extra precautions around wildfire smoke, which can cross the placenta and affect a developing fetus. Studies have found that exposure to wildfire smoke during pregnancy can increase the risk of premature birth and low birth weight. Researchers have also linked the toxic chemicals in smoke with maternal health complications including hypertension and preeclampsia.
What about other high-risk populations?
Certain chronic diseases including asthma, chronic obstructive pulmonary disease or other respiratory conditions can also make you particularly vulnerable to wildfire smoke. People with heart disease, diabetes and chronic kidney disease should take extra care to breathe clean air, the CDC says. The tiny particles in wildfire smoke can aggravate existing health problems, and may make heart attacks or strokes more likely, CARB warns.
Get ready for the next emergency
Living in Southern California means another wildfire is coming sooner or later. To prepare for the bad air, you can:
- Stock up on disposable respirators, like N95 or P-100s.
- Have clean filters ready for your A/C system and change them out when things get smoky.
- Know how to check the air quality where you live and work. The AQMD has an interactive map that’s updated hourly. Just type in an address and it will zoom in on the location. You can also sign up to get air quality alerts by email or on your smartphone.
- Know where your fire extinguisher is and keep it handy.
- If you have a heart or lung condition, keep at least five days’ worth of medication on hand.

Mark Sutton, an Imperial College London paleontologist, is not a punk.
“I’m more of a folk and country person,” he said.
But when Dr. Sutton pieced together 3-D renderings of a tiny fossil mollusk, he was struck by the spikes that covered its wormlike body. “This is like a classic punk hairstyle, the way it’s sticking up,” he thought. He called the fossil “Punk.” Then he found a similar fossil with downward-tipped spines reminiscent of long, side-swept “emo” bangs. He nicknamed that specimen after the emotional alt-rock genre.
On Wednesday, Dr. Sutton and his colleagues published a paper in the journal Nature formally naming the creatures as the species Punk ferox and Emo vorticaudum. True to their names, these worm-mollusks are behind something of an upset (if not quite “anarchy in the U.K.”) over scientists’ understanding of the origins of one of the biggest groups of animals on Earth.
In terms of sheer number of species, mollusks are second only to arthropods (the group that contains insects, spiders and crustaceans). The better-known half of the mollusk family tree, conchiferans, contains animals like snails, clams and octopuses. “The other half is this weird and wacky group of spiny things,” Dr. Sutton said. Some animals in this branch, the aculiferans, resemble armored marine slugs, while others are “obscure, weird molluscan worms,” he said.
Punk and Emo, the forerunners of today’s worm-mollusks, lived on the dark seafloor amid gardens of sponges, nearly 200 million years before the first dinosaurs emerged on land. Today, their ancient seafloor is a fossil site at the border between England and Wales.
The site is littered with rounded rocky nodules that “look a bit like potatoes,” Dr. Sutton said. “And then you crack them open, and some of them have got these fossils inside. But the thing is, they don’t really look like much at first.”
While the nodules can preserve an entire animal’s body in 3-D, the cross-section that becomes visible when a nodule is cracked open can be difficult to interpret “because you’re not seeing the full anatomy,” Dr. Sutton said.
Paleontologists can use CT scans to see parts of fossils still hidden in rock, essentially taking thousands of X-rays of the fossil and then stitching those X-ray slices together into one digital 3-D image. But in these nodules, the fossilized creatures and the rock surrounding them are too similar in density to be easily differentiated by X-rays. Instead, Dr. Sutton essentially recreated this process of slicing and imaging by hand.
“We grind away a slice at a time, take a photo, repeat at 20-micron intervals or so, and basically destroy but digitize the fossil as we go,” Dr. Sutton said. At the end of the process, the original fossil nodule is “a sad-looking pile of dust,” but the thousands of images, when painstakingly digitally combined, provide a remarkable picture of the fossil animal.
Punk and Emo’s Hot Topic-worthy spikes set them apart from other fossils from the aculiferan branch of the mollusk family. “We don’t know much about aculiferans, and it’s unusual to find out we’ve suddenly got two,” Dr. Sutton said.
Stewart Edie, the curator of fossil bivalves at the Smithsonian National Museum of Natural History, said that Punk and Emo’s bizarre appearances shook up a long-held understanding of how mollusks evolved. Traditionally, scientists thought that the group of mollusks containing snails, clams and cephalopods “saw all of the evolutionary action,” said Dr. Edie, who was not involved with the new discovery. “And the other major group, the aculiferans, were considerably less adventurous.” But Punk and Emo “buck that trend,” he said.
The new alt-rock aculiferans reveal the hidden diversity of their group in the distant past and raise questions about why their descendants make up such a small part of the mollusk class today. “This is really giving us an almost unprecedented window into the sorts of things that were actually around when mollusks were getting going,” Dr. Sutton said. “It’s just this little weird, unexpected, really clear view of what was going on in the early history of one of the most important groups of animals.”
The U.S. Food and Drug Administration this week set maximum levels for lead in baby foods such as jarred fruits and vegetables, yogurts and dry cereal, part of an effort to cut young kids’ exposure to the toxic metal that causes developmental and neurological problems.
The agency issued final guidance that it estimated could reduce lead exposure from processed baby foods by about 20% to 30%. The limits are voluntary, not mandatory, for food manufacturers, but they allow the FDA to take enforcement action if foods exceed the levels.
It’s part of the FDA’s ongoing effort to “reduce dietary exposure to contaminants, including lead, in foods to as low as possible over time, while maintaining access to nutritious foods,” the agency said in a statement.
Consumer advocates, who have long sought limits on lead in children’s foods, welcomed the guidance first proposed two years ago, but said it didn’t go far enough.
“FDA’s actions today are a step forward and will help protect children,” said Thomas Galligan, a scientist with the Center for Science in the Public Interest. “However, the agency took too long to act and ignored important public input that could have strengthened these standards.”
The new limits on lead for children younger than 2 don’t cover grain-based snacks such as puffs and teething biscuits, which some research has shown contain higher levels of lead. And they don’t limit other metals such as cadmium that have been detected in baby foods.
The FDA’s announcement comes just one week after a new California law took effect that requires baby food makers selling products in California to provide a QR code on their packaging to take consumers to monthly test results for the presence in their product of four heavy metals: lead, mercury, arsenic and cadmium.
The change, required under a law passed by the California Legislature in 2023, will affect consumers nationwide. Because companies are unlikely to create separate packaging for the California market, QR codes are likely to appear on products sold across the country, and consumers everywhere will be able to view the heavy metal concentrations.
Although companies are required to start printing new packaging and publishing test results of products manufactured beginning in January, it may take time for the products to hit grocery shelves.
The law was inspired by a 2021 congressional investigation that found dangerously high levels of heavy metals in packaged foods marketed for babies and toddlers. Baby foods and their ingredients had up to 91 times the arsenic level, up to 177 times the lead level, up to 69 times the cadmium level, and up to five times the mercury level that the U.S. allows to be present in bottled or drinking water, the investigation found.
There’s no safe level of lead exposure for children, according to the U.S. Centers for Disease Control and Prevention. The metal causes “well-documented health effects,” including brain and nervous system damage and slowed growth and development. However, lead occurs naturally in some foods and comes from pollutants in air, water and soil, which can make it impossible to eliminate entirely.
The FDA guidance sets a lead limit of 10 parts per billion for fruits, most vegetables, grain and meat mixtures, yogurts, custards and puddings and single-ingredient meats. It sets a limit of 20 parts per billion for single-ingredient root vegetables and for dry infant cereals. The guidance covers packaged processed foods sold in jars, pouches, tubs or boxes.
Jaclyn Bowen, executive director of the Clean Label Project, an organization that certifies baby foods as having low levels of toxic substances, said consumers can use the new FDA guidance in tandem with the new California law: The FDA, she said, has provided parents a “hard and fast number” to consider a benchmark when looking at the new monthly test results.
But Brian Ronholm, director of food policy for Consumer Reports, called the FDA limits “virtually meaningless because they’re based more on industry feasibility and not on what would best protect public health.” A product with a lead level of 10 parts per billion is “still too high for baby food. What we’ve heard from a lot of these manufacturers is they are testing well below that number.”
The new FDA guidance comes more than a year after lead-tainted pouches of apple cinnamon puree sickened more than 560 children in the U.S. between October 2023 and April 2024, according to the CDC.
The levels of lead detected in those products were more than 2,000 times higher than the FDA’s maximum. Officials stressed that the agency doesn’t need guidance to take action on foods that violate the law.
