Content:
A routine inspection and maintenance program for SWS piping and components to assure that corrosion, erosion, protective coating failure, silting, and biofouling cannot degrade the performance of the safety-related systems supplied by service water.52 8. For multi-unit sites with SWS cross-tie capability, the reviewer verifies that: a. The sharing of structures, systems and components does not significantly impair the ability of the SWS to perform its safety function, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units. b. Flushing and flow testing provisions, resulting from the implementation of Generic Letter 89-13, are applied to the cross-tie lines. c. Applicants proposing designs with only two SWS pumps per unit have addressed the provisions of Generic Letter 91-13 (Reference 14).53 For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.54 IV. EVALUATION FINDINGS The reviewer determines that sufficient information has been provided and his review supports conclusions of the following type, to be included in the staff's safety evaluation report. 9.2.1-11 DRAFT Rev. 5 - April 1996 The service water system (SWS) includes all components and piping from the SWS pump intake to the points of cooling water discharge. Portions of the SWS that are necessary for safe shutdown, accident prevention, or accident mitigation, are designed 55 to seismic Category I,
