SUBJECT:

James A. FitzPatrick Nuclear Power Plant Docket No. 50-333 Additional Information Regarding Local Leakage Rate Testing Correctlie Action Plan

REFERENCE:

NYPA letter, J. C. Brons to the NRC, dated April 8, 1988 (JPN-88-012).

Dear Sir:

The referenced letter requested an exemption from the requirements of 10 CFR 50 Appendix J, Section III.A.6(b), to res ore the normal Integrated Leakage Rate Test retest schedule of Section Ill.D(a). Attachment 11 to that letter contained a Corrective Action Plan (CAP) as technical justification for the exemption request, in a hiay 11, 1988, telecon with hiessrs. J. A. Gray, Jr. and J. A. Greene, your staff requested that the Authority provide additional supporting information to facilitate the NRC review of the CAP. That information is contained in two attachments to this letter.

Attachment I to this letter is a table noting all local leak rate test (LLRT) "as-found" failures for containment isolation valves. Notes to this table provide clarification of the information contained in the table.

Attachment 11 contains the LLRT data summaries from which the table in Attachment I was derived. These data summaries were previously submitted to the NRC as attachments to four individual Integrated Leakage Rate Test reports oser the past ten years and contain no new information. They are provided here to facilitate the staff review of the exemption request.

Should you or your staff have any questions regarding this matter, please contact hir. J. A. Gray, Jr. of my staff.

Very truly yours.

1 IDCAL LEAK RATE TEST FAILURES (coat.) pg. 6 of'6 ..

Notes:

1. A Local Laak Rate Test (LLRT) is performed on all primary containment penetrations each refueling outage. "As-found" failure is defined as exceeding the administrative 1y determined local leakage rate limit for any valve before maintenance is performed.

Maintenance (e.g., machining or lapping seating surfaces, replacing seat rings, adjusting operator, or packing adjustments) is performed prior to resuming power operation.

The FitzPatrick In-Service Inspection program sets leak rate limits that, when exceeded, require either more frequent testing or immediate repair (depending on the magnitude of the leak). Plant practice is to repair valves in lieu of more frequent testing. Since both this practice as well u real "as-found" failures result in maintenance being performed which improve the leakage characteristic of valves, no distinction is made in the LLRT test report between the two. Therefore, this more conservative practice results in indicated "as-found" failures in this table when there was no actual failure. Repaired valves are considered failurec for the purpose of this table if the. repair results in a significantly reduced leakage rate.

Valves also receivo routine preventative maintenance or parts replacement for environmental qualification concerns winich may result in changes in the leakage rate. Attachment II to this letter provides only the leakage rate results and the specific maintenance performed.

No indication is provided whether maintenance was performed due to the "as-found" leak rate or for other concerns. Therefore, valves which may not have exceeded their "as-found" acceptance criteria may be included in this table if there was a significant improvement in the leakage rate due to repair.

The FitzPt ick primary containment currently contains 112 testable penetrations, of which 64 are isolated by containment isolation valves (CIV). There are 172 CIVs on these penetrations in the LIJtT program. 33 of these valves are to be replaced as part of the CAP, and 14 others are being removed during the 1988 refueling outage. These 47 valves represent over 27% o* the current total. In addition to these valves, four CIVs were removed and eight were replaced since 1983 due to repeated local leakage rate "as-found" failures.

The 59 removed or replaced valves represent approximately one-third of the total number of containment isolation valves.

2. (MSIV) are subjected to the most severe duty (continuous The Main Steam saturated steam flow Isolation Valveg lbs/hr per valve) of 2.5x10 of any CIV. Since 1978, improvements in valve maintenance practices, including the purchase of the manufacturer's ceat maintenance tool, have improvei the leakage characteristics of the valves such that they now usually require refurbishment at four years intervals. Typically, two MSIVs will require maintenance during each refueling outage. The Authority considers this to be an acceptable level of performance.

3. Systems which are required to operate after accidents (RHR, Core Spray, HPCI, RCIC, and SLC) are designed to be leaktight systems (seismic, safety-related) and are periodically inspected. The containment isolation valves in these systems may be expected to open following an accident to mitigate the accident. Therefore, the "as-found" LLRT lee's 7es for these valves are not include in the calculation of the primary containment ILRT "a " und" condition.

4. The primary contaiment vent and purge isolation valves (27-AOV-111, 112, 115 4, 115, 115, 117, 118) were considered for inclusion in the CAP. Valve replacements and a . aalized periodic seat replacement program (such as the Millstone program) were evaluated but not considered cost effective or technically justifiable considering the current performance of the valves. The Authority will continue to reevaluate this situation in light of advancements in valve design and the continued performance of the valves. In the mean time, LLRT will be performed on these valves during each refueling outage, and maintenance will be performed whenever indicated.
