s for the ECCS is performed under SRP Section 3.2.1 and 3.2.2. 13. Review of the criteria used for postulating the effects of pipe breaks both inside and outside containment on ECCS is performed under SRP Section 3.6.2. This review includes criteria used for postulating the effects of pipe whip, jet impingement forces, and any related environmental conditions. 14. Review of the loading combinations (operational, LOCA, seismic, and thermal stratification loads) and the associated stress limits is performed under SRP Section 3.9.3. 15. Review of the adequacy of the inservice testing program for pumps and valves is performed under SRP Section 3.9.6. This review is to assure that the ECCS piping and component configurations allow for full flow testing of safety related pumps and check valves and provisions are made to allow for the use of advanced techniques to detect degradation and to monitor system performance. 16. Review of the structures housing the ECCS for the proper seismic classification is performed under SRP Sections 3.8.1, 3.8.2, and 3.8.3. 17. Review of the applicable inservice inspection requirements is performed under SRP Section 6.6. 6.3-4 Revision 3 - March 2007 18. Review of the thermal shock effect of water injected into the primary coolant system from the ECCS is performed, on a generic basis, under SRP Sections 5.3.2 and 5.3.3. 19. Review of compliance of the NUREG-0737 item II.K.2.15 requirements is performed under SRP Section 5.4.2.1. This review assures that B&W once-through steam generator tubes are designed with sufficient margin to assure that if the tubes are stressed under slug flow conditions, mechanical integrity will be maintained. 20. Review of the proposed preoperational and initial startup test programs is performed under SRP Section 14.2 to assure that they are consistent with the intent of Regulatory Guides 1.68. 21. Review of compliance of Task Action Plan items I.C.2 and I.C.6 of the NUREG-0737 requirements regarding procedures to
