A presidential blue ribbon commission says the US government 'has not inspired confidence' and recommends that a new agency take over the search for storage sites for nuclear waste.
A hearing of the Nuclear Regulatory Commission (NRC) pointed to apparent weaknesses in the regulation of nuclear plants.
Nuclear Regulatory Commission still insists that US nuclear plants with same design as Japan's stricken Fukushima Daiichi facility are safe. But watchdog groups cite failed venting system, which led to hydrogen explosions.
At a hearing Thursday, the Nuclear Regulatory Commission said things are fine. But it also acknowledged it is double-checking key items to verify preparedness in the wake of Fukushima.
At Fukushima Daiichi in Japan, nuclear reactor Unit 1 is being prepared for 'cold shutdown,' which requires flooding the reactor's containment structure with cold water to stop steam production.
Radiation 'hot spots' beyond the existing Fukushima evacuation zone spur Japanese officials to order more areas to be emptied. Residents are being given a month to leave.
Workers plugged a leak of highly radioactive water into the ocean from Japan's Fukushima Daiichi nuclear power plant Wednesday, even as they tried to prevent another hydrogen explosion in reactor No. 1 by injecting nitrogen gas.
Scientists point to several factors. On Thursday, the Japan nuclear crisis took a hopeful turn as engineers installed a cable to connect the Fukushima I nuclear power plant to the utility grid.
Fifty workers and fire hoses are all that remain at Japan's Fukushima I plant to cool three hot reactors and six pools containing spent fuel rods – perhaps for months to come.
Radiation exposure: Adding to the monumental losses after a Japanese earthquake and tsunami, problems at four nuclear reactors have residents near and far concerned about radiation exposure.
