D.C. earthquake shifted North Anna nuclear storage containers

LOUISA, Va. (AP) — Dominion Virginia Power says the Aug. 23 earthquake caused massive nuclear storage containers at its North Anna Power Station to shift, but they remained intact.

The Richmond-based utility said Thursday that 25 containers that store used fuel moved anywhere from one to 4.5 inches during the 5.8-magnitude quake. The containers weigh about 115 tons when full. Dominion is evaluating whether to move the containers back, but said they are still safely spaced.

The tremor shut down both reactors at the power station located about 40 miles northwest of Richmond after they lost power.

Dominion says the earthquake also caused cosmetic damage to concrete containers that hold other fuel-storage canisters but they didn't move. The containers also retained their structural integrity and maintained the used fuel inside in a safe condition.
