California’s Coast Crumbled This Month — 123 Nuclear Cans on a Bluff With Nowhere to Go
You’d think the scary part is the 123 steel canisters full of radioactive waste. It’s not. The canisters are fine. It’s the cliff holding them up that’s decided to leave.
123 canisters. ~3.6 million pounds of spent nuclear fuel. Sitting ~100 feet from a seawall the ocean is chewing on. And the only legally approved place to move it was cancelled in 2009.
This month, chunks of the Southern California coast fell into the Pacific during heavy waves and flooding. An oceanographer named Kim McCoy looked at the mess and thought about one spot: the beach at the shut-down San Onofre nuclear plant, where the waste is set in concrete a stone’s throw from the water.

🧩 Dumb Mode Dictionary
| Term | What it actually means (plain words) |
|---|---|
| Spent nuclear fuel | The used-up fuel rods from a reactor. Still insanely radioactive. Stays dangerous for thousands of years. |
| Dry cask storage | The waste sealed inside thick steel-and-concrete tubes, sitting out in the open air on a concrete pad. Think a giant thermos that can’t be thrown away. |
| Coastal erosion | The sea slowly eating the land. Every big storm takes another bite off the cliff face. |
| Decommissioned | The plant is switched off and being torn down. San Onofre closed in 2013. The buildings go — the waste stays. |
| Yucca Mountain | The one site Congress legally approved to bury this stuff permanently, in the Nevada desert. Built most of it. Then killed it. |
| CISF | “Consolidated interim storage facility” — a stopgap parking lot for waste while a permanent site gets sorted. The US still doesn’t have an open one. |
🌊 What's actually happening on that beach
Quick recap in case you just walked in: San Onofre is a closed nuclear plant on the coast between LA and San Diego. The plant is basically gone. The waste is not.
- 123 canisters, holding roughly 3.6 million pounds of spent fuel, sit on a pad near the shoreline.
- They’re about 100 feet from a walkway that protects the seawall.
- Rising seas, storm waves, and El Niño swell can wash away that walkway. This month’s storms already ate coastline nearby.
Oceanographers say the bluff needs constant watching.
The cliff did not ask for opinions. The cliff is just leaving.
To be straight with you: most experts say the near-term risk of erosion actually cracking a canister is low. The canisters are certified and sealed. The problem isn’t tonight. The problem is that “temporary” here has quietly turned into “forever,” and forever is now sharing a fence line with the Pacific.
📅 How 17 years of 'temporary' became permanent
The plan was simple: store the waste on-site for a bit, then ship it to Yucca Mountain. Follow the dates.
- 1968 — San Onofre starts generating power.
- 1987 — Congress names Yucca Mountain the future permanent burial site.
- 2009–2010 — The Yucca Mountain project gets defunded and its license pulled. Nothing replaces it.
- 2013 — San Onofre shuts down for good.
- 2020 — The last of the spent fuel is loaded into dry casks on the coastal pad.
- 2026 — Storms crumble the coastline. The canisters are still there.
See the problem? They cancelled the destination before the plant even closed.
The plan was to store the waste temporarily at San Onofre while Yucca Mountain got built. Yucca Mountain was cancelled in 2009. “Temporarily” is now in year 17.
🗺️ Wait — why can't they just move it?
This is the part that breaks people’s brains, so let me keep it dead simple.
“Somewhere safe” does not legally exist. Not “it’s expensive.” Not “it’s far.” It literally does not exist as an approved place.
- Every move needs Nuclear Regulatory Commission (NRC) sign-off, an environmental review, and a licensed place to receive it.
- Moving the casks even 100 feet inland still needs a legal destination. There isn’t one.
- A CISF (that interim parking lot idea) has been fought in court for years. None is open.
Former NRC chairman Gregory Jaczko has said that of any site in the country, San Onofre is the most important one to empty. And it’s the one that can’t be emptied.
Here’s the cursed part: the United States has enough missiles to end civilization, but cannot legally park 123 metal tubes in a desert.
🔬 So is this fine or not? (the honest answer)
Both sides, one line each, no spin:
The NRC / operator: The steel canisters are built to take waves, salt, and time. Near-term risk is low.
Independent scientists (Scripps, etc.): Sure — but nobody wants to run the real-world “canister sits in seawater for a decade” test to find out.
The uncomfortable truth: that seawater-submersion scenario has never been tested at scale. There’s no cleanup playbook, no price tag, just a “before” and an “after.”
Nobody wants to be the person who turned out to be right.
The ocean is not waiting for the paperwork.
🏛️ What happens next
Realistically, three doors:
- Congress funds a brand-new permanent site (years, maybe decades).
- A CISF finally clears the courts and opens (also years).
- Nothing happens and the casks keep sunbathing on the bluff.
Guess which one has the momentum.
Congress could vote to fund a permanent repository any time. Congress has other things going on. The Pacific does not.
Headline from 2031, if we keep this pace:
“San Onofre Canisters Enter 22nd Year of ‘Temporary’ Storage; New Seawall Walkway Also Erodes”
Cool. So the Waste Is Stuck, the Cliff Is Shrinking, and the Data Is All Public… Now What the Hell Do We Do?
ಠ_ಠ
Here’s the thing nobody’s connected yet, and it’s the whole reason this section exists: all the data is free and public, and nobody has stacked it together. The suits at the county offices don’t know this. You’re about to.
Five plays. Each one starts with public government data and a first move you can make tonight. No nuclear degree required.
🗺️ The Three-Portal Map Nobody Built
Three free government portals have never been laid on top of each other: NRC waste-site locations, USGS Coastal Change Hazards cliff-recession rates, and NOAA sea-level rise projections. Put them on one map and you’ve got a county-level risk layer that emergency planners have literally never seen in one place.
Sell it as a one-page county PDF to coastal county emergency-planning departments — the people whose job is exactly this, who’ve never had the three datasets together.
Example: A planner in San Luis Obispo County opens a $500 one-page PDF and sees, for the first time, the nuclear pad, the erosion rate, and the 30-year sea line on a single image.
Timeline: Screenshot all three for San Diego County tonight — that screenshot IS your cold-email pitch. First paid PDF within 2–3 weeks.
🏠 The Proximity Report the Title Company Skipped
Coastal real estate near nuclear-waste pads is mispriced, because the risk isn’t in any listing or title report. But NRC dry-cask coordinates plus USGS recession rates spell out a very real liability a buyer would want before they sign.
Pull the free data, build a clean one-page “proximity risk” report, sell it to coastal-CA property investors doing due diligence before they close. This is white-hat — you’re handing buyers a fact the market ignored.
Example: An investor eyeing a San Clemente duplex pays $120 for a one-pager showing the pad distance and the bluff’s yearly retreat rate before making an offer.
🧮 The Post-Yucca Tab Nobody's Keeping
Nuclear operators paid fees into a federal Nuclear Waste Fund for decades to build Yucca Mountain. It got cancelled. Nobody keeps a public running total of what storing this stuff has cost taxpayers since the cancellation.
Build one honest, sourced Google Sheet. Journalists and advocacy groups cite these things — and citations turn into paid research requests.
Example: An environmental reporter finds your sheet on r/nuclear, cites the total in a story, then emails you a $600 request to break the numbers down by year.
📝 The Disclosure Line Every Coastal Lawyer Will Want
Storm-erosion news opens a short window: coastal-CA real estate attorneys will be tempted to update their boilerplate disclosures — right up until the news cycle moves on and the urgency fades.
Draft a one-page “nuclear proximity + coastal erosion” disclosure addendum. Sell it as a plain Word download, not a service. Move before the window shuts.
Example: A San Diego closing attorney buys the $49 Word template off Gumroad rather than writing the clause from scratch.
📊 The Trust-Fund Gap Hiding in the 10-K
Every nuclear plant has a decommissioning trust fund, and the balances are disclosed in SEC 10-K filings on EDGAR. Nobody cross-checks those balances against updated relocation-cost estimates — because “the cliff is eroding, move the casks” was never in the original math.
Pull the balances for US coastal nuclear sites, compare to realistic relocation costs, sell the gap analysis to ESG bond and municipal-debt analysts who have zero coverage on this beat.
Example: A muni-bond analyst pays $900 for a one-pager showing the trust fund is short of what a forced coastal relocation would actually cost.
