[In san Clemente,] Edison is building a massive concrete monolith for more storage, using a Holtec design called Hi-Storm UMAX. It will hold about two-thirds of the plant's spent fuel in 73 stainless-steel canisters about 125 feet from the ocean. The 25-foot structure is about half-buried with the underground foundation just above the mean high-tide line. Tall cranes and swarms of hard hats are moving construction ahead.
The dry casks are designed to keep spent fuel confined only for decades, while the health standard for a permanent repository covers hundreds of thousands of years -- longer than humans have roamed Earth. If the radioactive waste sits around in temporary storage for hundreds of years, it could be neglected and eventually forgotten.
So one outcome that nobody seems to want is for a temporary site to eventually become permanent by default.
