y identified. For fluid systems important to safety, the classification tables in the SAR should identify system components such as pressure vessels, heat exchangers, storage tanks, pumps, piping, and valves, have suitable footnotes defining interfaces, and be in sufficient detail so that there is a clear understanding of the extent of those portions of the system that are classified as seismic Category I. The MEB also performs the following reviews for the SRP sections indicated: 1. Determines the acceptability of the quality group classification of system components in-accordance with SRP Section 3.2.2. This information may be combined with the information in this SRP section which may result in cross-referencing rather than repetition of the information. 2. Verifies that systems and components important to safety that are designated as seismic Category I items are designed in accordance with the regulatory guides, industry codes and standards that are referenced in SRP Sections 3.2.2, 3.9.1 through 3.9.3, and 3. Determines the adequacy of the inservice testing program for pumps and valves in accordance with SRP Section 3.9.6. II. ACCEPTANCE CRITERIA Acceptance criteria.is based on meeting the relevant requirements of the following regulations: 1. 10 CFR Part 50, Appendix A, General Design Criterion 2, as it relates to the requirements that structures, systems, and components important to safety shall be designed to withstand the effects of earthquakes without loss of capability to perform necessary safety functions. 2. 10 CFR Part 100, Appendix A, as it relates to certain structures, systems, and components being designed to withstand the Safe Shutdown Earthquake (SSE) and remain functional. These plant features are those necessary to assure: a. the integrity of the reactor coolant pressure boundary, b. the capability to shut down the reactor and maintain it in a safe shutdown condition, c. the capability to prevent or mitigate the consequences of accidents which
