r completeness and for conformance to Appendix J. The review of the reactor containment leakage rate test program at the OL stage specifically includes the following: 1. Containment Integrated Leakage Rate Test (Type A Test) Those systems not vented or drained should be identified and the reason for not venting or draining should be stated. Piping and instrumentation diagrams and process flow drawings are used by the reviewer to confirm that in the vented and drained condition, the isolation valves are exposed to the test air pressure and differential pressure, i.e., the systems are vented and drained both upstream and downstream of the containment isola- tion valves. 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 operation or a LOCA. 6.2.6-4 Rev. 2 - July 1981 Test pressures for containment penetrations should be stated in the test program and in the Technical Specifications. The test pressure is accept- able if it is the maximum calculated containment accident pressure. 3. Containment Isolation Valve Leakage Rate Test (Type C Test) All containment isolation valves requiring a Type C test should be listed in the test program. By reference to the piping and instrumentation dia- grams, the reviewer confirms that all isolation valves to be tested have been listed. Test pressures for isolation valve Type C tests should be included in the test program and Technical Specifications. Special testing procedures for dual-type containments should be identified. CSB assures that the applicant has provided a leakage testing program and
