The staff should provide the Commission information on its plans for conducting public workshops. The public workshop (s) to be conducted during the public comment period should be of sufficient duration and depth to provide meaningful insights into the approaches described in the documents.
In addition, the staff should provide the Commission information on its plans for training the NRC staff 1) on the risk-informed regulatory approach (es) contained in the regulatory guidance and standard review plan docr.ments and 2) in overall PRA methods and techniques. Particular attention should be given to increasing basic user-level knowledge of PRA methods at the regional level.
! (EDO) (SECY Suspense: 9/30/97)
The staff should continue to evaluate the proposed decision criteria and the methods of ensuring conformance to the criteria.

In particular, the staff should explore the following areas to add clarity and consistency to the process.
- 1. The feasibility of assigning assurance levels for conformance to decision criteria. j
- 2. 'The use of point values for comparisons with decision criteria, without any explicit consideration of ,
uncertainty (i.e., how consideration of uncertainty !
I should be explicitly considered in conjunction with using point values -- for example, use of probability l limits) l l
- 3. -The implications of small increases in core damage f requency (CDF) and large early release frequency (LERF) codified in.the guidance documents, as a function of the uncertainty associated with the PRA j results.
- 4. Codifying in the guidance documents the experience i gained from the pilots to provide additional guidance on the " increased management attention" process when !'
proposed changes approach the guidelines. ,
- 5. Clarifying the distinction between risk-informed and '
risk-informed, performance-based regulatory approaches.
The staff should continue to pursue the long range goal of improving the overall quality and consistency of PRAs. performed by different licensees by promoting high quality standards.
The staff should continue its efforts.to complete, in a timely taanner , the pilot applications of risk-informed regulation, and to complete the draft regulatory guidance and standard review plan for inservice inspection.
