t's conclusions. 5. For a small break loss-of-coolant accident, the SRXB reviews the potential for the addition of un-borated water into the core from reactor coolant pump seals, and the potential for additional core damage caused by reactivity transients from the un-borated water.18 6. The SRXB verifies that the core physics data used by the applicant, or by the staff in independent audit analyses, are the appropriate data to be used.19 The PERB review of this SRP section covers the following area:20 AEBPERB as part of its secondary review responsibility provides an evaluation of fission 21 product releases and radiological consequences. This effort is described in the appendices to this SRP section and their results are included in the safety evaluation report (SER) writeup. Review Interfaces22 The SRXB reviews fuel failure modes and burst correlations for compliance with 10 CFR 50.46 as part of its fuel design review in SRP Section 4.2. 23 The RSBSRXB will coordinate, as required and by request, other branch evaluations that 24 interface with the overall review of this SRP section as follows: The Auxiliary Systems Branch (ASB) review of Chapters 9 and 10 of the applicants SAR includes an evaluation of auxiliary systems (e.g., service water system, component cooling system, ultimate heat sink, condensate storage facility) to confirm that these systems can supply all the functions required to support the ECCS in performing its function during and following a loss-of-coolant accident. Upon 25 request, ASB will verify that the auxiliary system described by the applicant for the safety analysis supply all the functions required. ASB also, upon request from RSB, reviews the failure modes analysis of the ECCS to verify that an adequate analysis of possible failure modes of ECCS equipment and the effect of the failure modes on the ECCS performance has been provided.26 1.
