WASHINGTON – Energy Secretary Steven Chu suggested Sunday that Japan’s nuclear crisis might make it less likely that new nuclear reactors are built near large American cities, just one of many safety changes that could be forthcoming as U.S. officials review reactor safety.

“Certainly where you site reactors and where we site reactors going forward will be different than where we might have sited them in the past,” Chu said in response to questions about the Indian Point nuclear plant near New York City. “Any time there is a serious accident, we have to learn from those accidents and go forward.”

Meanwhile, the chairman of the Nuclear Regulatory Commission said his agency will again review how U.S. nuclear plants store spent fuel from nuclear reactors. The state of the spent fuel pools at the Fukushima Dai-ichi plant has been a major concern as Japanese officials try to stem the release of radiation and bring the reactors under control.

“Five days ago everybody was worried about earthquakes and tsunamis and the reactors cooling,” NRC Chairman Gregory Jaczko said. “Today everybody is worried about the spent fuel pools. Until this is resolved we are not going to ultimately know what the most important factors are in terms of what needs to be addressed.”

The Food and Drug Administration said Sunday that the United States is not importing any foods from the affected area of Japan, and the agency is working with Customs and Border Patrol to screen other Japanese food imports to make sure they are not tainted. They are also checking food that may have passed through Japan.
