Content:
g 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. 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 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 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. CSBSCSB assuresensures that the applicant has provided a leakage testing program 44 45 and has specified the maximum leakage 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 DRAFT Rev. 3 - April 1996 6.2.6-8 included in the technical specifications. The reviewer determines that the test provisions are adequate to confirm the bypass leakage specified. Preoperational and periodic test reports are primarilyreviewed by the appropriate NRC Regional Officeby the Office of Inspection and Enforcement.46 In SECY 93-087 (Reference 6) the staff recommended that the interval for Type C testing be changed from 24 months, as specified in Appendix J, to 30 months. The Commission approved this recommendation in its SRM dated July 21, 1993. Since no applicable regulation has been issued for this position, a partial exemption from
