SUBJECT:

STAFF REQUIREMENTS - SECY-97-101 - PROPOSED  !

l RULE, 10 CFR SECTION 50.76, " REPORTING l RELIABILITY AND AVAILABILITY INFORMATION FOR l 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 l 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 i Commission on whether the voluntary approach remains a viable

method of meeting regulatory needs. This periodic update may be t

incorporated, as appropriate, in the quarterly updates to the PRA i implementation plan.
