Representatives of the nuclear energy industry once again this week asked the NRC to adopt a performance-based approach to minimize the release of radioactivity from damaged fuel in a severe accident, while agency staff reiterated its earlier recommendation to require external filters for the containment vents of early-model boiling water reactors.
“A performance-based approach to filtration provides the greatest overall improvement in plant safety with sufficient filtration,” said Maria Korsnick, Constellation Energy Nuclear Group’s chief nuclear officer and chief operating officer. “The industry approach has the advantage of retaining the filtered radionuclides in containment. The desire is to prevent land contamination.”
Korsnick added that a performance-based approach that would specify results rather than methods to attain them would require plant-specific analyses. She noted that the NRC’s independent Advisory Committee on Reactor Safeguards “supports this approach”.

Earlier today, the Nuclear Energy Institute released a five-minute video explaining the comprehensive and tailored response strategy that it is implementing across the industry to enhance nuclear plant safety in the face of extreme natural events.
To produce the high-definition video, NEI acquired first-of-its kind footage of the deployment of new emergency response equipment at U.S. nuclear energy facilities. The video also features animation and interviews with industry leaders and technical staff discussing nuclear plant safety.
The diverse and flexible (“FLEX”) response strategy developed by industry addresses the major challenges encountered at the Fukushima Daiichi power station following the March 11, 2011, earthquake and tsunami: the loss of power to maintain effective reactor fuel cooling.
Additional on-site portable equipment is being acquired to help ensure that every U.S. nuclear energy facility can respond safely to extreme events, no matter what the cause. The equipment ranges from diesel-driven pumps and electric generators to ventilation fans, hoses, fittings, cables and satellite communications gear. It also includes support materials for emergency responders.
