Four more casks on the pad

This summer's loading campaign moved the oldest used fuel from the Unit 1 pool into four steel-and-concrete casks. The pad now holds 28.

The dry cask pad: a row of tall grey concrete casks on a slab inside the fence, the sea behind

Used fuel leaves a reactor hot, in every sense, and spends its first years in a deep pool of water inside the fuel building, where it cools and its radioactivity falls steeply. Once it has cooled enough, it is sealed inside a welded steel canister, the canister is set inside a concrete cask, and the cask is moved to the pad: a reinforced slab inside the protected area, in view of the security posts.

This summer's campaign loaded four casks from the Unit 1 pool over six weeks, with the plant at full power throughout. The pad now holds 28 casks, each watched by temperature and radiation monitors and inspected on a schedule set by the federal regulators whose resident inspectors observed the loading.

A cask gives off less radiation at its surface than a person receives on a long flight, and the pad's boundary dose is a small fraction of what the South Coast receives from the sun and the rocks in a year. The pad is sized for the life of both units.

The used fuel pad is part of the plant tour. Read more on the station page.

    Warm water and a run of calm days sent more drift kelp than usual into the offshore intake. The traveling screens handled it, and every strand went back to the sea.
