With U.S. Nuclear Plants Under Scrutiny, Too, a Report Raises Safety Concerns

On Thursday, the Union of Concerned Scientists, an environmental and nuclear watchdog group based in Cambridge, Mass., accused the federal Nuclear Regulatory Commission in a report of allowing companies that operate plants to ignore, or delay repairs to, leaky pipes, electrical malfunctions and other problems that could escalate into something more serious.
“It’s like the spinning wheels on a slot machine,” David Lochbaum, the author of the report and the director of the organization’s nuclear safety program, said in a prepared statement. “One ingredient showing up causes a puddle on the floor. Two ingredients yield a near miss. All three ingredients showing up can cause nuclear disaster.”
The report by the Union of Concerned Scientists examined 14 instances in 2010 in which significant problems at nuclear power facilities set off special inspections by federal regulators — incidents characterized by the regulators as “near misses.” Reports on such incidents are made available publicly by the regulatory commission.
Twelve of the events involved lingering safety problems, among them leaky roofs and floods near safety equipment, faulty pumps, rusty pipes, fires and inadvertent shutdowns. Two others involved compromises in plant security, though details on those were not made public.

The NRC and Nuclear Power Plant Safety in 2010
A Brighter Spotlight Needed
The crisis at the Fukushima Daiichi nuclear plant in Japan following the March 11 earthquake and tsunami is a stark reminder of the risks inherent in nuclear power. One of its consequences has been heightened concern about the safety of nuclear power facilities in the United States.
The Nuclear Regulatory Commission, the federal agency responsible for ensuring that U.S. nuclear plants are operated as safely as possible, gets mixed reviews in a March 2011 UCS report, The NRC and Nuclear Power Plant Safety in 2010: A Brighter Spotlight Needed. The report—the first of an annual series—was prepared and scheduled for release before the crisis in Japan began to unfold, but the disaster makes the report’s conclusions more timely than ever.
Authored by UCS nuclear engineer David Lochbaum, the report examines 14 “near-misses” at U.S. nuclear plants during 2010 and evaluates the NRC response in each case. The events exposed a variety of shortcomings, such as inadequate training, faulty maintenance, poor design, and failure to investigate problems thoroughly.
Since NRC inspections cannot reveal more than a fraction of the problems that exist, it is crucial for the agency to respond effectively to the problems it does find. The report offers examples of both effective and ineffective responses.
