lure of the pressurizer relief tank system or portions of the system not designed to seismic Category I, and which are located close to 32 safety-related systems, will not as a result of their failure preclude essential operations of DRAFT Rev. 3 - April 1996 5.4.11-6 these safety systems. Reference to the general arrangement and layout drawings for structures and systems will be necessary. 7. The reviewer determines that other systems inside containment are protected from the effects of high-energy line breaks and moderate-energy leakage cracks in the pressurizer relief system. Layout drawings are reviewed to assureensure that other systems are not 33 located close to the pressurizer relief system, or that protection from the effects of failure will be provided. 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.34 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided and his that the review 35 supports conclusions of the following type, to be included in the staff's safety evaluation report (SER):36 The pressurizer relief tank system includes components and piping such as the pressurizer relief and safety valve connections to the tank, the relief tank spray system piping, the nitrogen supply piping, and piping leaving the tank to the cover gas analyzer and reactor coolant drain tank.
