Content:
provided to prevent damaging water (steam) hammer from such mechanisms as voided discharge lines, water entrainment, and steam bubble collapse. If the normal water supply is above the discharge lines, voided lines are prevented by proper vent location, filling, and venting procedures. The vents should be tested on a periodic basis and located for ease of operation to prevent the possibility of voiding the liquid-filled discharge lines. NUREG-0927 provides guidance for water hammer prevention and mitigation. 5.4.13-14 March 2007 18. The reviewer confirms that the ICS capability is sufficient with respect to the plant’s ability to cope with, and recover from, an SBO of a specified duration by determining compliance with Regulatory Guide 1.155, Positions C.3.2, C.3.3, and C.3.5, as they relate to the design of the ICS. This review is coordinated with the review of the SBO event under SRP Section 8.3.1. 19. The reviewer verifies that the test results for containment isolation valves indicate that the valves will isolate under expected conditions, as discussed in Generic Letter 89-10, Supplement 3. 20. The reviewer verifies that a leakage reduction program has been implemented and that the program and ICS design meet the criteria of NUREG-0737, item III.D.1.1. For standard DC reviews under 10 CFR Part 52, the reviewer should follow the procedures above, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard DCD, including ITAAC, site interface requirements, and COL action items, meet the acceptance criteria given in Subsection II. SRP Section 14.3 contains procedures for the review of the DCD for the standard design, including the site parameters, interface criteria, and ITAAC. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis
