Nuclear Plant Safety

The NRC has issued its final interim staff guidance describing one acceptable method for conducting integrated assessments of external flooding hazards at nuclear energy facilities. The guidance is intended for use in cases where a re-evaluation of the flooding hazard exceeds levels defined by the utilities’ flooding design basis.

The new guidance, JLD-ISG-2012-05, is the latest in a large volume of work the NRC staff is developing to address lessons learned from the 2011 reactor accident in Japan. Interim staff guidance clarifies issues that are not addressed in the standard review plan for nuclear energy facilities.

NRC staff last week outlined several options it is considering for creating a more integrated regulatory framework, as recommended by the agency’s post-Fukushima task force.

The options, discussed at a Nov. 8 public meeting, include clarifying the role of voluntary industry initiatives, creating a decision process for determining appropriate safety margins, and adding a new category in the regulations to address beyond-design-basis matters.

Equipment-sharing program at Memphis, Phoenix locations augments industry protocol to pool safety equipment in event of emergencies

WASHINGTON, D.C., Oct. 25, 2012—The nuclear energy industry is adding another layer of safety and public protection by developing regional centers for critical equipment that could be needed to maintain safety in the event of an extreme event at America’s nuclear energy facilities. All companies that operate nuclear energy facilities approved a contract to develop two regional response centers managed by Pooled Equipment Inventory Co.

The regional response centers will be located near Memphis and Phoenix and capable of delivering supplemental emergency equipment to any of America’s nuclear energy facilities within 24 hours, enabling them to safely manage a loss of electrical power and/or cooling water supply. The equipment and materials provided by the regional response centers supplement the additional portable equipment purchased at all 64 nuclear energy facilities that also can be utilized and shared during a site emergency.

Pooled Equipment Inventory Co. has been providing a shared inventory service to meet emergent equipment needs to the nuclear industry for more than 30 years. The company has established an alliance with AREVA to implement the regional response centers by expanding its capability to provide services that include emergency response planning, procurement and outage services.

The NRC’s latest analysis of faults near the Diablo Canyon nuclear energy facility in California confirms that the plant’s design could withstand earthquakes near the site, the agency said in a statement.

The NRC’s work is laid out in research information letter (RIL) 12-01, “Confirmatory Analysis of Seismic Hazard at the Diablo Canyon Power Plant from the Shoreline Fault Zone.” The RIL, part of an ongoing effort to better understand earthquake sources near Diablo Canyon, focuses on a recently identified source, the “Shoreline fault” about a kilometer offshore from the plant.
