RESPONSE TO NOTICE OF VIOLATION INSPECTION REPORT NOS. 50-338/85-12 and 50-339/85-12 NRC COMMENT:
Technical Specification surveillance requirement 4.8.2.3.2 requires in part that each 125 volt battery be verified OPERABLE at least once per seven days by ensuring the electrolyte level of each pilot cell is between the minimum and maximum level indication marks.
2-PT-85 (D.
C.
Distribution System) is the' procedure the licensee' uses to verify the requirements of Technical Specification surveillance 4.8.2.3.2.
Step 5.2 of.2-PT-85 requires that the individual performing the procedure verify
. electrolyte of the pilot cells is between the maximum level and one inch below that' level.
Contrary to the above, when 2-PT-85 was performed on April 30, 1985, the
' electrolyte levels were initialed-as satisfactory when, in fact, electrolyte level for the pilot cell on at.least one battery (2-II) was above the maximum level indication mark.
This is a Severity Level IV Violation (Supplement 1) for Unit 2.
RESPONSE
1.
CORRECTIVE STEPS **'HICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED:
After notification by the NRC Resident. Inspectors, the batteries were reinspected.
The pilot cell on battery 2-II was found to be slightly above the upper fill mark (less than one-eighth inch). The remaining battery cells were also inspected and several were found to be slightly high (less than one quarter inch).
The slightly high levels were returned to within the acceptable range.
The vendor was contacted and.he advised that, even though cell electrolyte levels were slightly high, no operational or performance problems would exist.
1-PT-65 and 2-PT-85 were revised to ensure that when the electrolyte level ot' 3 pilot cell is not within the req'uired band, the deviation is noted on the test critique sheet, a deviation report is initiated, the shift supervisor is notified, the pilot cell level is adjusted to be within the band, and all other cells of the effected battery are checked and if not within the band, noted as such on the critique sheet and deviation report and adjusted to also be within the band.
Training was provided to electricians performing battery surveillance.
The training was based on the revisions to 1-PT-85 and 2-PT-85.
