The Challenge
California's existing commercial spent nuclear fuel inventory includes 291 canisters stored at four locations.
California's 291 commercial spent fuel canisters are stored at SONGS, Diablo Canyon, Rancho Seco, and Humboldt Bay.
| Location | Canisters | Strategic Considerations |
|---|---|---|
| SONGS | 123 | Permanently shut down. Spent fuel remains stored on coastal property leased from the U.S. Navy. |
| Diablo Canyon | 142 | California's last operating nuclear power plant. |
| Rancho Seco | 21 | Permanently shut down. Fuel remains stored on site decades after closure. |
| Humboldt Bay | 5 | Former coastal nuclear plant site in a seismically active region. |
| Total | 291 | California commercial spent fuel inventory. |
