Dear Dr. Travers:
|SUBJECT: ||PROPOSED HIGH-LEVEL GUIDELINES FOR PERFORMANCE-BASED ACTIVITIES |
During the 475th meeting of the Advisory Committee on Reactor Safeguards, August 29 - September 1, 2000, we met with representatives of the staff to discuss the proposed high-level guidelines for performance-based activities. Also, during our June 7-9, 2000 meeting, we discussed this matter with representatives of the staff and the Public Citizen Critical Mass Energy Project. We had the benefit of the documents referenced.
Conclusions and Recommendations
|1. ||We support the staff's proposal to apply the guidelines for performance-based activities to an example regulation. |
|2. ||The guidelines should explicitly state that the performance levels and reliability parameters should be set at the highest practical level. |
|3. ||Guidance should be given on the extent to which multiple performance parameters that provide redundant information should be used to satisfy the defense-in-depth philosophy. |
|4. ||Expanded discussions should be provided in the guidelines of the responses to the relevant questions that appeared in the Federal Register Notice of May 9, 2000. |
The proposed high-level guidelines provide a systematic method to incorporate performance-based principles into regulatory activities. These guidelines are comprehensive. They incorporate important principles and strategies and Commission policy and direction. These guidelines provide consistency among new performance-based regulations and coherence with the current body of regulations. The determination of performance parameters using the proposed hierarchical structure is logical and systematic.
The guidelines are structured to, among other things, assess performance-based regulatory changes. One such guideline, II.C(2), states that:
| ||An assessment would be made of the performance criteria and the level in the performance hierarchy where they have been set. In general, performance criteria should be set at a level commensurate with the function being performed. In most cases, performance criteria would be expected to be set at the system level or higher. || |
The guidelines should explicitly state that the performance criteria should be selected at the highest practical level, and that this principle should be applied to the other guidelines. This enhances licensee flexibility and reduces regulatory burden while maintaining the appropriate level of safety.
The guidelines are also structured to assess consistency and coherence with overarching NRC goals and principles. In cases in which redundant performance parameters are identified, the staff will need to provide guidance on balancing the use of a minimum number of parameters with the use of multiple parameters consistent with the defense-in-depth philosophy. We believe that the guidelines should state the degree to which redundant, overlapping, or confirmatory performance indicators are required to validate the data or provide defense-in-depth.
The discussion of the draft guidelines in the May 9 Federal Register Notice contains a number of relevant questions related to the application of performance-based regulatory guidelines. In Attachment 2 to the proposed Commission paper, the staff responded to public comments related to these questions. The guidelines should more clearly identify the staff positions stated in response to these questions, because many users of the guidelines may have these same questions.
We look forward to reviewing the report to the Commission on the trial applications of these guidelines.
