(i) 1.0 PURPOSE

~

~

The purpose of this report is to present the test procedure used and the test results obta'ned during a test program. The objec-tive of the test program was to determine the conformance of One (1) Gate Valve Assembly, Part Number 79190 (Serial Number 25709), to the Flow Interruption Test requirement specified in References 2.1 and 2.2, in accordance with Reference 2.3.

2.0 R'EFERENCES 2.1 Borg Warner Corp. , Nuclear Valve Division, Report No.1836, titled " Flow Interruption Test for Part No. 79190, Supplied to Tennessee Valley Authority Bellefonte Nuclear Plant Units 1 and 2," dated 9 February 1981.

SUMMARY

. 3.1 One (1) Gate Valve Assembly, described in Paragraph 1.0 and hereafter referred to as " Specimen," has been subjected to Flow Interruption Testing as described in this report. During the final test cycle, the Specimen indicator plate retaining nuts loosened causing the plate to make contact with the eyebolts. The plate was slightly bent as a result of the impact. All other results conformed to the specification requirements and no further adverse effects were noted.

3.2 All results are presented for evaluation.

. AETL 5.1.6 The Specimen was subjected to three additional test runs from the fully closed position to the off seat position until flow was established. The pressure was maintained at a minimum of 2675 psi.

The completion of these test cycles fully satisfied the test requirement specified in Reference 2.2, Paragraph 6.2.4(b). The qualification requirements for Part No. 77910 were also satisfied on completion of Flow Interruption Testing.

5.1.7 Following each test cycle, the Specimen was inspected for any discrepancies that may have occurred during testing. During the last test cycle, the indicator plate retaining nuts on the Specimen had loosened causing the plate to make contact with the eyebolts.

T.he plate was slightly bent as a result, but no significant damage or discrepancies were reported. No further adverse effects were detected during testing. This concluded testing and the Specimen was returned to Borg Warner, Nuclear Valve Division.
