SUBJECT:
SECONDARY CONTAINMENT LEAK RATE TEST REPORT
Dear Sir:
A Secondary Containment Leak Rate Test (8.7.3) was satisfactorily performed on March 17, 1982, and is hereby reported as required by PNPS Technical Specification 6.9.C.3.
This test was performed to verify secondary contain-ment integrity after the inner Reactor Building Trucklock door failed to pass the leak rate test and was fixed.
This secondary containment leak rate test demonstrated that the Standby Gas Treatment System (SGTS) was capable of maintaining greater than % inch of water vacuum in the secondary containment, as required by PNPS Technical Specification 4.7.C.1.c.
The test was initiated through the use of permanently installed test switches which simultaneously isolated the normal secondary containment ventilation system and initiated the Standby Cas Treatment System. The data was cor-rected for zero SGTS flow conditions.
Review and approval by the Boston Edison Company's Nuclear Engineering Depart-ment of the acceptance criteria of this test ensures that satisfactory results from its performance verifies the integrity of secondary containment.
The data obtained during the test is enclosed.
Very truly yours, WM 8206000339 820527 R. D.
