Flood

The following news article originally appeared in NEI’s Nuclear Energy Overview.

The NRC has issued for public comment draft interim staff guidance for U.S. nuclear energy facility operators to perform certain flooding hazard assessments in response to a request for information the agency issued in March as part of its response to the Fukushima accident.

The March request calls for licensees to use the latest available information and analysis methods to analyze site-specific hazards, including stream and river flooding, hurricane storm surges, tsunamis, and dam failures.

Industry/Regulatory/Political

  • The post-Fukushima response steering committees of the nuclear energy industry and Nuclear Regulatory Commission reviewed accomplishments and work in progress during a joint meeting last week. Nuclear energy industry representatives highlighted completion of inspections for potential flooding and seismic activity, validation of procedures and equipment readiness for loss of off-site electrical power, purchase of additional portable safety equipment, and selection of a vendor for a regional response center. Work in progress includes establishing guidance and conducting further inspections for flooding and seismic assessments and integrating emergency operating procedures and severe accident management guidelines.

The NRC has issued for public comment draft interim staff guidance for U.S. nuclear energy facility operators to evaluate their sites’ responses to reanalyzed flooding hazards that exceed levels the plants were designed to withstand.

The guidance outlines an acceptable method for reactor licensees to meet one of the requirements outlined in a March 12 request for information the agency issued as part of its response to the Fukushima accident.

The NRC’s plan to require licensees to evaluate the potential loss of a nuclear energy facility’s ultimate heat sink, or long-term cooling source, as part of flooding hazard re-evaluations will extend the time needed to complete the work, the industry said last week—a situation the industry believes is unnecessary and inadvisable.

The following news article originally appeared in NEI’s Nuclear Energy Overview.

Inspections related to flood protection have begun at nuclear energy facilities based on industry guidance endorsed by the Nuclear Regulatory Commission in late May. These inspections, or “walkdowns,” address part of the NRC’s March request for detailed information on several post-Fukushima issues the agency identified as the top priorities—Tier 1—among the 12 recommendations of the NRC’s task force. Seismic walkdowns got under way earlier this month. The industry is awaiting NRC comments on guidance for responding to three orders that address the other Tier 1 issues.
