Egmmissioner McGaffiaan's comments on SECY-97-101 - Prooosed Rule.10 CFR Section 50.76. "Recortina Reliability and Availability Information for Risk-Sionificant Systems and Eau 1oment" I approve the staff's recommendation to accept the voluntary aaproach proposed by industry, but regret that total consensus could not be reacled. ' note the staff's view that the data not included in the voluntary approach "should be readily available" and that the lack of such data will require compensatory neasures which. "could, necessarily, introduce some additional uncertainty and probably a conservative bias in some of the derived parameter estimates." I question whether this state of affairs is in anyone's interest and encourage the staff and industry to continue to work together to expand the voluntary program. I also agree with the Chairman's comments on the need for staff to periodically update-the Commission on how the voluntary data program is working, perhaps by incorporation in the quarterly PRA implementation plan updates.

FROM: Jo . , Secretary
SUBJECT:
STAFF REQUIREMENTS - SECY-97-101 - PROPOSED RULE, 10 CFR SECTION 50.76, " REPORTING RELIABILITY AND AVAILABILITY INFORMATION FOR RISK-SIGNIFICANT SYSTEMS AND EQUIPMENT" The Commission has approved the staff's recommendation to accept the voluntary approach proposed by NEI for obtaining reliability and availability data for key safety systems.
The staff should continue to work with industry representatives to improve the content of the voluntary data. These improvements should seek to expand the voluntary program to minimize 1) uncertainty in data and 2) the use of compensatory measures to derive needed parameter estimates. The staff should periodically update the Commission on its efforts to work with industry to address shortfalls and limitations in the data, and advise the Commission on whetber the voluntary approach remains a viable method of meeting regulatory needs. This periodic update may be
> incorporated, as appropriate, in the quarterly updates to the PRA implementation plan.
