SUBJECT:
INTERIM REPORT - REGULATORY EFFECTIVENESS OF THE STATION BLACKOUT RULE As part of an evolving program to address regulatory effectiveness to make Nuclear Regulatory Commission (NRC) activities and decisions more effective, efficient, and realistic, the NRC Office of Nuclear Regulatory Research is reviewing regulations, starting with the station blackout (SBO) rule, to determine if the requirements are achieving the desired outcomes and if the expected costs were realistic.
This report presents an evaluation of the effectiveness of the SBO rule based on a comparison of the regulatory expectations to the corresponding outcomes. A set of baseline expectations was established from the SBO rule and related regulatory documents in the areas of coping capability, risk reduction, emergency diesel generator reliability and unavailability levels, and value-impact. The report concludes that although some issues may need attention, the SBO rule was effective and the industry and the Nuclear Regulatory Commission costs to implement the SBO rule were reasonable considering the outcome.
The report is being distributed for internal comments. Our intentions are to finalize the report based on the comments and subsequently obtain external peer comments, and use each assessment,to make recommendations to improve regulatory effectiveness.
We are now specifically interested in comments regarding (1) the reasonableness of the.
approach, (2) the appropriateness of the conclusions, and (3) other regulations that should be assessed. Please provide your comments by November 10.
' It is our undarstanding that NRR will coordinate the review by and receipt of comments from the regions.
