San Onofre nuclear power station: nuclear waste moves from wet pools to dry storage

Nuclear waste moves from wet pools to dry storage at San Onofre

1 down, 43 to go before the plant’s cooling pools are empty and its dry storage system is full By TERI SFORZA | | Orange County Register July 18, 2019  It took the better part of two days, but Canister No. 30 — a 50-ton behemoth full of spent nuclear waste — was successfully moved from a fuel-handling building, rolled across the bluff on a giant transporter, then inserted into its steel-and-concrete vault in the Holtec Hi-Storm UMAX dry storage system at San Onofre Nuclear Generating Station.

The delicate, deliberate dance was originally projected to wrap up by early morning Wednesday, July 17, but finished up about 6 a.m. Thursday. And as far as majority owner and operator Southern California Edison is concerned, that’s just fine and dandy……..

Critics continue to worry about the integrity of those canisters — which have scratches from their descent into the vaults — over what could be decades in the San Onofre’s salty seaside atmosphere. They demand that the waste be moved from what they deride as a “beachfront nuclear waste dump” immediately, but that requires action from a federal government that has dithered on the issue for some 70 years.

The road to here

San Onofre’s reactors powered down in 2012 after tubes in its brand-new steam generators cracked, resulting in a small radiation leak. After local opposition to restarting it appeared insurmountable, San Onofre was shuttered for good in 2013.

The plant will be dismantled – a $4 billion job that’s expected to take at least another decade – and all the spent fuel currently cooling in its spent fuel pools will be transferred to dry storage by next year……..
