artial exemption from the requirements of Section III.A.1(a) of Appendix J. This section of 6.2.6-7 DRAFT Rev. 3 - April 1996 Appendix J requires that a Type A test be terminated if, during this test, potentially excessive leakage paths are identified which would either interfere with satisfactory completion of the test or which would result in the Type A test not meeting the applicable Appendix J acceptance criteria. Section III.A.1(a) further requires that, after terminating a Type A test due to potentially excessive leakage, the leakage through those leakage paths be measured using local leakage testing methods and repairs and/or adjustments to the affected equipment be made. The Type A test shall then be conducted. For the System 80+ plant, the applicant proposed that leaks occurring during the Type A test that could affect the test results would not prevent completion of this test if: (a) the leaks are isolated for the balance of the test; (b) the leaking component had a "pre-maintenance" local leak rate test whose results, when added to those from the Type A test, are in conformance with the acceptance criteria of Appendix J; or (c) a "postmaintenance" local leak rate test of the leaking component(s) is performed and the results, when added to those from the Type A test, conform to the acceptance criteria of Appendix J. The staff accepted the applicant's proposal as an Appendix J exemption since the proposed alternative accomplishes the intent of the regulation.43 2. Containment Penetration Leakage Rate Test (Type B Test) All containment penetrations should be listed in the test program. By reference to piping and instrumentation diagrams, the reviewer confirms that all penetrations have been listed. The program should identify any penetration not requiring leakage testing and the reason for not requiring a test should be stated. The reviewer confirms that those penetrations not requiring testing cannot result in leakage to the atmosphere during normal
