SUMMARY:

The Nuclear Regulatory Commission (NRC) is soliciting public comment on the “Draft Final Technical Study of Spent Fuel Pool Accident Risk at Decommissioning Nuclear Power Plants.”

As the number of power reactors involved in the decommissioning process increases, the ability to address regulatory issues generically has become more important. After a nuclear power plant permanently shuts down and the reactor is defueled, the traditional accident sequences that dominate operating reactor risk are no longer applicable. The predominant source of risk remaining at permanently shutdown plants involves accidents associated with spent fuel stored in the spent fuel pool.

Following a Commission meeting held on March 17, 1999, the NRC staff formed a technical working group to evaluate spent fuel pool accident risk at decommissioning plants. The staff set out to develop a risk-informed technical basis that could be used to develop rulemaking and to establish a predictable method for reviewing future exemption requests and to identify the need for any research in areas of large uncertainty. The staff intends for this approach to meet the NRC outcome goals of maintaining safety, reducing unnecessary regulatory burden, increasing public confidence, and improving efficiency and effectiveness.

The NRC released a preliminary draft version of the technical basis study in June 1999. A public workshop to discuss the report was held in July 1999. Numerous comments and other input were received from the public and the nuclear industry. The NRC has revised the report to address the comments received and to incorporate needed changes based on the results of outside technical reviews.

All comments received will be considered before the final report is published as the basis for initiation of rulemaking activities.

DATES:

The comment period expires April 7, 2000. Comments received after this date will be considered if practical to do so, but the staff is able to assure consideration only for comments received on or before this date.

ADDRESSES:
