DOCKET /NOS. 50-266 AND 50-301-REPLY TO NOTICE OF VIOLATION INSPECTION REPORTS-50-266/89021 AND 50-301/89020 POINT BEACH NUCLEAR PLANTS, UNITS 1 AND 2 Your letter dated Jul'yl21, 1989-forwarded the results of the
~
. Enforcement. Conference conducted on June 2, 1989 reported as
' Inspection. Reports Nos.' 50-266/89021 (DRP)-and 50-301/89020 (DPR).. In response to your. letter, Wisconsin Electric submitted a reply dated August.21, 1989.
This reply included a commitment to submit.a revised battery testing program by October 1, 1989.
Aftertreceiving NRC concurrence with this program, licensee planned to submit an amendment application to incorporate'this program linto the PBNP Technical Specifications.
Our reply also
- stated that there-was no'need for periodic testing during the remainder-of 1989 and, therefore, there was adequate time to resolve:the battery testing issues.
Upon further review of the~ installation and testing records for batteries D105 and D106, we have determined that a load test per Technical Specification 15.4.6.B.4 is-required during the Fall of11989.- These batteries were placed in service in February 1985, however, the acceptance tests were performed in September, 1984.- Therefore, we believe a more conservative interpretation of the Technical Specifications requires testing this year.
A performance test will be conducted on each of these batteries during the Unit 2 outage presently scheduled for September 22, 19891to November 9, 1989.
This performance test will consist of a constant current capacity test per the requirements of Section 6-of IEEE. Standard 450-1987, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations".
Initial conditions will be as described in Section 6.1 of this standard, omitting' requirements (1) and (2).
The test will be a capacity test at a constant discharge current of 795 Amps (corrected for H
initial electrolyte temperature per Section 6.3 of IEEE 450-1987).
This corresponds to the manufacturer's one hour rating for the batteries.
The test will continue at this 8910040173 890926 PDR ADDCK 05000266 8

'Page 2 discharge rate until a battery terminal voltage of 105 volts (1.75. volts per cell) is detected.
Demonstrated battery capacity will. be calculated per Section 6.5 of IEEE 450-1987 and evaluation of the need for battery replacement will be conducted per Section 7 of the same standard.
These tests will be similar to those which will be proposed in our October 1,1989 submittal and will adequately demonstrate 'the adequacy of the D105 and D106 batteries while fulfilling the requirements of Technical Specification 15. 4. 6.B. 4.
The f uture testing'of these batteries will be based upon NRC-approved Technical Specification requirements resulting from the testing program to be proposed in our October 1,1989 submittal and the evaluation of the.results of the above-discussed tests.
If you have any questions regarding the above, please contact us.
Very truly yours,.
