With the events in Japan on everyone’s mind, it’s of course to be expected that seismic safety at nuclear power plants in the U.S. becomes a hot topic. This article discusses how the Nuclear Regulatory Comission has an on-going study to assess the seismic hazard of existing and proposed nuclear power plants in the eastern 2/3 of the country, where the risk is greater than was originally thought.
Nearly six years before an earthquake ravaged Japan’s Fukushima Daiichi nuclear power plant, U.S. regulators came to a sobering realization: seismic risks to nuclear plants in the eastern two-thirds of the country were greater than had been suspected, and engineers might have to rethink reactor designs.
