.:[m. ].

It should be noted that the valve assembly has successfully passed the flow interruption test since the specimen performed its required function in the required time and upon completion o'f the test demonstrated 0 leakage in the direction the valve was flow tested.

The increased leakage in the reverse direction is the result of debris in the test media which NN N'w caused a slight scratch on the upstream side of the gate.

shows no evidence of being caused by valve failure to closeExa under flow.

1.0 PURPOSE The purpose of this report is to present the test procedure used and the test results obtained 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.

l 3.2 All results are presented for evaluation.

/kEYL 4.0 TEST CONDITIONS AND TEST EQUIPMENT 4.1 Test Conditions Unless otherwise specified herein, all tests were performed at room ambient conditions: defined as a temperature of 73118 F 0

(23 110*C), a relative humidity of 50 130 percent, and a baro-metric pressure of 28.5 +2.0, -3.0 inches of mercury absolute (725 +50, -75 mm of mercury absolute).

4.2 Test Equipment The test equipment presented in the Appendix was calibrated, as l

required, in accordance with MIL-C-45662A and is traceable to the National Bureau of Standards (NBS). The NBS traceability records are maintained on file in the AETL Quality Control Office.
