J..
Commissioner McGaffigan's Comments on SECY-98-171 I approve publishing this rulemaking package for a ninety-day public comment period. However. like my colleagues. I do not agree with the staff proposal regarding " reduction in the margin of safety associated with any technical specification."
l-l As the Chairman points out, the definition of " reduction in margin of safety
..." would extend the requirements for prior agency approval to underlying aspects (e.g.. input assumptions) of parameters that affected the selection of technical specifications and result in the newly controlled parameters being treated essentially the same way as values in the technical specifications.
This is the wrong way to go.
It is clear from my colleagues' and my vote that the margin of safety criterion (50.59(c)(2)(vii) in the proposed rule) and the definition will need to be fixed in the final rule. My concern at this point is that the staff ;
discuss a wide enough array of options in the Federal Reaister notice to ensure that the proposed rule will not have to be renoticed before being finalized. Commissioner Diaz has proposed to simply delete the criterion and definition as not needed. The Chairman has proposed essentially a new )
i definition. Another option would decouple the last criterion from technical specifications and focus instead on a new criterion relating to performance of fission product barriers (e.g.. RCS pressure containment pressure. etc), with minimal changes being allowed up to specified limits, perhaps utilizing a graduated approach similar to the approaches proposed for other criteria.
Comment should be solicited on this option as well. ,
I believe that the staff has done a good job in proposing options for defining
" minimal" for consequences of an accident or malfunction. On probability.
however, the staff has essentially only said that NEI 96-07 satisfies the proposed NRC standard for a " minimal" increase. That is a good step forward, and will bring regulatory stability. I believe that in choosing the word
" minimal" the Conmission intended to grant greater flexibility than the NEI
)- 96-07 "so small" or negligible standard. The staff should continue to try to give better definition to " minimal" as it pertains to " probability of occurrence of an accident" or " probability of equipment malfunction" and solicit comment on this.
I Finally. I endorse the use of enforce.. lent discretion under Section VII of the Enforcement Policy as the rulemaking proceeds for those 50.59 violations of little or no safety / risk significance. The staff should treat (vice er
.-.----y =v .-- _ ,- -
l
" consider treating" as proposed by staff) as minor violations cases where the violation of existing rule requirements would not constitute a violation under j the rule were it revised as proposed. I do not object to documenting such !
minor violations in inspection reports because the rule is still in a proposed revision stage. l

RULEMAKING ON 10 CFR PARTS 50,52, AND 72 REQUIREMENTS CONCERNING CHANGES, TESTS AND f i
EXPERIMENTS AND STAFF RECOMMENDATIONS ON 1 CHANGES TO OTHER REGUI.ATIONS AND ENFORCEMENT l
POLICY l The Commission has approved publication, for a 60 day public comment period, the proposed rulemaking that would revise 10 CFR 50.59 and related provisions in Parts 50,52 and 72 concerning the processes controlling licensee changes, tests and experiments for production and utilization facilities and for facilities for independent storage of spent nuclear fuel and high-level radioactive waste. The Voting Record, which includes the Commissioner votes and this Staff Requirements Memorandum, should be published in the Federal Reaister notice to clearly inform stakeb!ders on preliminary positions taken by the Commission (Enclosed).'
The Commission also approves the staff's recommendations for handling violations of 10 CFR F,.59 and 72.48, including staff plans for exercise of enforcement discretion, while rulemaking is underway.
The Commission requested that the staff specifically solicit public comment in the Federal {
Reaister notice on:
- 1. A wide array of options for the margin of safety criterion (50.59(c)(2)(vii) in the l
proposed rule) and its definition including: a) deleting the criterion and definition, '
b) a new definition as described in Chairman Jackson's vote, and c) an option which would decouple the last criterion from technical specifications and focus j
instead on a new criterion relating to performance of fission product barriers (e.g.,
reactor coolant system pressure, containment pressure, etc), with minimal changes being allowed up to specified limits, perhaps utilizing a graduated approach similar to the approaches proposed for other criteria.
