Large spent nuclear fuel storage casks that shifted during a 2011 earthquake in Virginia will remain where they are.

Dominion Virginia Power will not be required to move the casks back to their original places at the 1,953 MW North Anna nuclear power plant, according to the Richmond Times-Dispatch. The earthquake caused 25 out of 27 casks, each 16 feet tall and weighing 115 tons, to shift on a concrete pad as much as 4.5 inches.

The U.S. Nuclear Regulatory Commission said the casks did not show any other signs of damage, and met NRC spacing requirements where they are, the article said. Moving the casks would take a lot of work and could potentially expose workers to radiation.
