n B, guidance on venting and draining is available in Section 8.0 of NEI 94-01, Rev. 0. 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 rate 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 a LOCA. Test pressures for containment penetrations should be stated in the test program and in the Technical Specifications. The test pressure is acceptable if it is the calculated peak containment internal pressure related to the DB LOCA. 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 diagrams, 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. The reviewer ensures that the applicant has provided a leakage rate testing program and has specified the maximum leakage rate which may occur from bypass (or dilution) leakage for dual-type containments. Potential leakage paths which bypass the annulus or the auxiliary building areas or may leak directly to atmosphere must be identified. The total amount of containment bypass leakage to the environment must be specified and included in the technical specifications. The reviewer determines that the test provisions are adequate to confirm the bypass leakage rate specified. Preoperational and periodic tests are reviewed by the appropriate NRC Regional Office.
