PART II - Local Leakage Rate Tests A. Type B Test Results Local leakage rate testing for the containment electrical penetrations has been performed twice since the last type A test report, once in the late spring of 1977 and again in the fall of 1978. The results were acceptable for both series of tests.
The local leakage rate testing for the containment electrical penetrations checks the leakage through the penetration 0-ring seals on the bolt-on flanges and the leakage from the penetration catisters. The total leakage from the electrical penetrations is the sum of the leakage from the 0-ring seals and the canister leakages. A summary sheet is included for each eerf es of electrical penetration tests.
Other type B local leakage rate tests measure the leakage through the personnel airlock, the equipment hatch and the fuel transfer tube.
These results are noted on the test results leakage su==ary after each section of electrical penetration leakages.
It should be noted that there are two leakage tests (OSr 1.47.1 and OST 1.47.83) performed on the airlock. OST 1.47.1, which is a type C leaksgo test, pressurizes the door seals and uses a bubble flow detector to check for leaks.
If the seals are leaking, this device will detect this by bubbling.
This test is performed af ter each opening, or if the airlock is being used for multiple entries, then at least once every,three days.
Since the last type A report, there
_ve been approximately six occurrences where seal problems were found.
By either lubricating and/or replacing the old seals, the leaks were stopped as subsequent rctesting proved.
In OST 1.47.83, which is a type B leakage test, the total airlock leakage rate is r easured. The results from this test can be found on the test results leakage summary, after each tabulated section of the individual electrical penetration leakages. REVISION 1 oG I 'h
