Dear Mr. Keppler:
In accordance with Reference 1, this is to inform you of degradation discovered in the primary reactor containment during periodic Type B and C surveillance leakage rate testing while in a shutdown condition.
As a result of conducting a periodic Type C leak test on the High Pressure Service Water Conthinment Isolation Valve, the leak flow rate determined from the valve exceeded the permissible leak flow rate as defined in Technical Specifications (Reference 2).
During the conduct of Type B leakage tests, the leakage rate from Electrical Penetration Unit No. 5 exceeded the allowable leakage rate.
The test leakage rate from the HPSW Containment Isolation Valve was determined to be 2.39 SCFH.
The leakage rate from Electrical Pene-tration Unit 5 was 48.83 SCFH, the majority of which was through the test chamber boundary, of the Containment Building wall.
The Acceptance Criteria is 0.375 SCFH* for each penetration.
The tests were performed on May 23, 1982.
Prompt notification of
+
test results to Paul Pelke, Region III, U.
S. Nuclear Regulatory Commission, was accomplished at 0915 on May 24, 1982, by L. S.
- Goodman, LACBWR Operations Engineer.
Notification of the HPSW Containment j
- Shall not exceed 1% of leakage rate L where L is 37.5 SCFH.
