SUMMARY

OF NRC-NUMARC MEETING TO DISCUSS PROPOSED RESOLUTION OF'NRC COMMENTS ON PROPOSED NUMARC SCREENING METHODOLOGY LICENSE RENEWAL REPORT Ca May 31, 1990, the staff met with representatives of NUMARC to discuss the proposed resolution of staff questions and comments on proposed NUMARC screening methodology contained in a NUMARC topical report submitted October 6,-1989.

During this meeting, NUMARC described how the original methodology had-been modified to account for more recent information on acceptable screening approaches presented by the staff at Commission and ACRS meetings on the proposed Part'54 rulemaking.

In addition, NUMARC discussed with the staff its' proposals for resolving staff comments contained in a letter from W. Travers to E.:Griffing dated February 7,-1990. A copy of the presentations made'by NUMARC are enclosed.

While the staff has deterniined that the proposed modifications of the NUMARC methodology are more consistent with the present staff's thinking concerning

-acceptable screening approaches, the staff notes that there are some areas where the proposed methodology continues to differ from the proposed criteria

- contained in the Part 54 rulemaking.

The two principle areas where the staff and NUMARC currently disagree are the definition of an established effective program-for license renewal and in'the scope of equipment important to license renewal. The NUMARC proposals for the requirements of established effective programs provide much greater latitude in creditingslicensee programs where specific program elements important for t

license renewal may not have been reviewed and accepted by~the staff. NUMARC also presented proposals for the identification of structures, systems ano components which contain one category which appears to significantly limit the plant structures and systems important to. license renewal to only those necessary to satisfy a very small group of specific regulations. ' Recognizing that the the rulemaking process, the staff will not be able to approve any NUMARC-

}dd requirements for these specific topics are still undergoing revision as part -of proposed screening methodology until the definitions and screening criteria

[>

used within the NUMARC report are judged equivalent to the specific requiremants t(

contained in the rule on license renewal.

Given the, substantive nature of other proposed changes to the NUMARC screening methodology, report previously received and recognizing that there are some issues that will-remain unresolved pending action on the final rulemaking, the staff recommended that NUMARC revise the screening methodology report consistent with the NUMARC presentation and to resubmit the revised report for staff review.

- SYSTEMS AND STRUCTURES o

REVISED TO GO TO DEFINITIONAL APPROACH SIMILAR TO STAFF'S STEP 1:

Systems and structures important to license mo..I are:

(a)

Safety related systems and structans, which are those relied upon to remain functional during and following design basis events to ensure the integrity of the reactor coolant pressure boundary, the capability to shut down the nactor and maintain it in a safe shutdown condition, and the capability to prevent or mitigate the consequences of accidents that could result in potential offsite exposure comparable to the Part 100 guidelines.

Design basis events are defined the same as in 10 CFR 50.49 (b)(1).

(b)

' Nonsafety related systems and structures whose failure could directly prevent satisfactory accomplishment of the safety functions by safety-related systems or structures as specined in paragraph (a) of this definition.

(c)-

Systems and structures which are necessary to meet the requirements of:

(a) 10CFR50.48 (Fire Protection)

(b) 10CFR50.62 (ATWS)

(c) 10CFR50.63 (Station Blackout) o DEFINITION USED IN METHODOLOGY SHOULD MATCH FINAL LICENSE RENEWAL RULE FOLLOWING RESOLUTION OF COMMENTS h

FUNCTION.

Examples:

- A program which trends the failure rate of a large population of similar relays and requires corrective L

action if the failure -rate exceeds a prescribed action i

level can be considered an effective program.

Relays, l

or other components, which can be considered in this sense are limited to those which are part sf multiple channel systems; in which a single failure would not i

result in loss of system safety function.

- A trending

>rogram which trends the known leading degradation parameters for a component and requires corrective action if predetermined limits are exceeded.

Tracking of fatigue usage through cycle counting for i

reactor vessel head studs is an example of such a program.

Example:

- Pump inservice testing programs, which periodically l

would be considered effective for demonstrating the-operability safety function.

Such testing, l

however, would not cover degradation mechamsms l
