The Nuclear Regulatory Commission will  likely fall behind schedule in issuing a key safety measure designed for  U.S. power plants in the wake of Japan’s nuclear reactor meltdown last  year, the agency’s chairman told a Senate committee Thursday.

(John McDonnell - THE  WASHINGTON POST) The NRC’s five commissioners testified before the  Senate’s Environment and Public Works Committee on the safety progress  of the U.S. nuclear industry a year after an earthquake caused a nuclear  disaster at Japan’s Fukushima Daiichi plant.
NRC Chairman  Gregory Jaczko said U.S. nuclear power plants would likely miss the  agency’s five-year goal for implementing orders aimed at avoiding the  effects of earthquakes on the plants. An agency task force on the  Japanese disaster said the measures should be put in place at the  nation’s 104 nuclear power plants by 2016.
But Jaczko said the  earliest completion date for key seismic upgrades at the plants would be  in 2017, and 2019 for low-risk plants.
“This is an area in which  we recognize that there is new information that tells us the plants may  not be designed to the right seismic standards. For this one to be  taking so long is a bit of a concern to me,” Jaczko said.
Commissioner  George Apostolakis told Sen. Barbara Boxer (D-Calif.), chairman of the  Senate panel, that plants in California would complete their seismic  upgrades within five years.
Jaczko said that in the next few  days, the NRC will begin taking comments from nuclear power plant  officials on a proposed rule that would require the plants to maintain  operations during blackouts indefinitely. Currently plants are required  to maintain functions during four to eight hours of blackouts. In Japan,  the plant lost power during the tsunami and earthquake, which speeded  its meltdown.
On Monday, the NRC officially issued three orders  to the nation’s power plants, Jaczko said: Plants must develop and  implement measures to keep spent fuel rods cool after an extreme natural  disaster; they are required to have sturdier venting systems to help  prevent pressure-induced explosions; and they must have a reliable read  of water levels in spent fuel containers.
The orders were  considered the highest priority by the NRC task force on the Fukushima  disaster, which issued its recommendations in July.
At the  hearing, the commissioners worked to assure the Senate panel that a  Fukushima-like event would not happen in the United States.
“Our  infrastructure, our regulatory approach, our practices at plants, our  equipment, our configuration, our designed basis, would prevent  Fukushima from occurring under similar circumstances at a U.S. plant,”  said commissioner William Magwood. “I just don’t think it would happen.  But we can still improve, and we are going to improve.”
