In their vote sheets, the Commission approved the staff's recommendations and provided some i
additional comments with the following exceptions:
Chairman Jackson, although she preferred mandatory conformance with a risk-informed 10 CFR Part 50, she was in agreement with Commissioners McGaffigan and Merrifield that the recommendation to not allow selective implementation of a voluntary approach was prematurely before the Commission and disapproved the recommendation at this time.
Commissioner Dicus, Diaz and Merrifield disapproved the staff's recommendation that the current rulemaking initiatives associated with paragraph (a)(3)/(a)(4) of 10CFR50.65 (maintenance rule) continue as planned. Commissioner Diaz, in his vote on February 8, recommended a two step process to risk inform the scope of the maintenance rule in the short term and long term. Commissioner Dicus agreed with Commissioner Diaz.
Commissioner Merrifield recommended suspending the rulemaking and including it in a later rulemaking package with scope changes. Commissioner Diaz supplemented his vote on April 14,1999, which supported the expeditious revision of 50.65(a)(3)/(a)(4)if the requisite ("should" to "shall") assessment of plant configuration is restricted to risk-significant structures, systems, and components; and, the requisite assessment is conducted using the methods stated in the Staff Requirements Memorandum (SRM) for SECY-97-173. Commissioners Dicus and Merrifield agreed with Commissioner Diaz'
q
. 1 approach. Sub'sequently, the Commission held a public meeting on May 5,1999.
. Specific Commission direction regarding the rule language and development of the regulatory guidance was provided in the SRM on the Maintenance Rule Commission briefing of May 5,1999, which was issued on May 13,1999. Regarding the overall
' scope of the Maintenance Rule (50.65), the Commission approved changing the existing
. scope to conform to the risk-informed regulatory framework being developed as part of Option 2.
Commissioner Diaz disagrees with the draft SRM language regarding Policy issue 3 but recognizes that there is a majority. As stated in COMNJD-99-003, although Commissioner Diaz continues to believe NRC has a regulatory framework which provides adequate protection, the Advisory Committee on Reactor Safeguards (ACRS) raised questions that have implications for adequate protection and backfit. Therefore, he believes that as a matter of prudence, the Commission should await ACRS and Office of General Counsel analyses, and conduct further open consideration before the final direction is provided to the staff.
Subsequently, the comments of the Commission were incorporated into guidance to staff as reflected in the SRM issued on June 8,1999.
