Content:
bility of the low-pressure portions of the ECCS that interface with the RCS to withstand full RCS pressure is performed under SRP Section 3.12. 2. Evaluation of the ability of the ECCS to mitigate the consequences of a spectrum of loss-of-coolant accidents is performed under SRP Section 15.6.5. 3. Evaluation of the capability of the new applicant's ADS systems and the PWR core melt stabilization system to support mitigation of severe accidents is performed under SRP Section 19.0. 4. Review of the effects of pipe breaks outside containment on ECCS is performed under SRP Section 3.6.1. This review includes the evaluation of the effect of pipe whip, jet impingement forces, and environmental conditions. 5. Review of the acceptability of, and environmental qualification test program for, ECCS equipment is performed under SRP Section 3.11. This review includes consideration of the post-accident environmental design and source term considerations described in TMI action plan item II.B.2 and II.K.3.24 of NUREG-0737. 6. Review of the capability of those auxiliary systems essential for ECCS operation (service water system, component cooling system, ultimate heat sink, and condensate storage facility) is performed under SRP Sections 9.2.1, 9.2.2, 9.2.5, and 9.2.6. The evaluations 6.3-3 Revision 3 - March 2007 include portions of the power conversion systems (e.g., steam supply lines, steam generators, feedwater systems) which interface with the reactor coolant system in such a way as to influence the course of a loss-of-coolant accident (LOCA) for a particular plant. 7. Review of the capability and design of the pneumatic supply system for those applicants which use a pneumatic supply for the ADS function is performed under SRP Section 9.3.1. 8. Review of the adequacy of ECCS-associated controls and instrumentation with regard to the features of automatic actuation, remote sensing and indication, and remote control is performed under SRP Section 7.3. This review includes
