Dear Sir:
A Secondary Containment Leak Rate Test (8.7.3) was satisfactorily performed on October 28, 1984 and is hereby reported as required by PNPS Technical
-Specification 6.9.C.3.
This test was performed to verify secondary containment integrity at Refueling Outage #6 prior to refuel.
This secondary containment leak rate test demonstrated that the Standby Gas
' Treatment System (SGTS) was capable of maintaining greater than 1/4 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 Gas Treatment System.
- Review and approval by the Boston Edison Company's Nuclear Engineering l-
- Department 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, W. ~ D. Harrington PF6: caw
