PERIODIC REACTOR PLANT CONTAINER AIR LOCKS AND 48-INCH BUTTERFLY VALVES LEAKAGE AND PERFORMANCE TEST. SECTION II. FIRST PERFORMANCE. Test Results DL-S-206 (T-641103A)

OSTI ID:4256881
The purpose of this test was to prove the integrity of the 48-in. butterfly valves by means of an alr pressure test, visual inspection and operating check. The leak rate for both sets of butterfly valves, which were tested simultaneously, was different for each run. The pressure decreased at a rate of 5.3 psi/hr during the first run, while the pressure during the second run, after the valves had been opened and closed approximately 10 times, decreased at a lower rate or 3.7 psi/ hr. Because of this, a definite leak rate could not be obtained. Apparently the valves are not reseating properly. (auth)
