1 COMMISSIONER DIAZ' COMMENTS ON SECY-98-015 I approve the publication and use of Regulatory Guide (RG) 1.174 and Standard Review Plan (SRP) Chapter 19, to be announced through the Federal Register notice, as modified below.
I support Commissioner Dicus' comments regarding making the RG and SRP consistent with the SRM for SECY-97-287, and the removal of references to current licensing basis (CLB). In the SRM for SECY-97-205, the Commission deferred decisions related to the CLB until February 26,1999, when the associated issues including commitment management will be resolved. The staff:;hould recommend replacement for the "CLB" in SEC'(-98-015, consistent with Commission's views expressed in the SRMs for SECY-97-205 and SECY-97-287.
Consistent with the SRM for SECY-97-287, the staff should incorporate the experience gained from risk-informed pilot programs into future updates of the RG and SRP. The periodic review and update of the RG and SRP, should be tracked in the PRA Implementation Plan.
In addition to the current NRC support ofinitiatives to develop PRA standards, the staff should closely monitor industry efforts to develop processes (e.g., peer review, cross comparison, or certification program) to assess the scope, leve' if detail and quality of the PRAs used in risk-informed regulatory applications. The disc- n in the current RG 1.174 and SRP Chapter 19 on this topic is a good starting point, but eve NRC reviewers can benefit from alditional l
specific guidance in how to assess the q sy of the PRA submitted for review. I would like to see enhanced discussions in this area in future RG and SRP revisions.
