is reasonably achievable, in accordance with 10 CFR 50, Appendix I. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the 10.4.1-5 Revision 3 - March 2007 proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. The SAR is reviewed to determine that any allowed MC system degraded operation does not have an adverse effect on the reactor primary system or secondary system in the case of pressurized water reactors. 2. The reviewer evaluates the MC system design to verify that: A. Means have been provided for controlling and correcting condenser cooling water leakage into the condensate. B. Upon request, the MC system is reviewed for the compatibility of the materials of construction with the service conditions and the methods used to reduce the corrosion and/or erosion of MC tubes and components. 3. The reviewer uses engineering judgment and the results of failure modes and effects analyses to determine that: A. The failure of a MC and the resulting flooding will not preclude operation of any essential systems. Reference to sections of the SAR describing plant features and the general arrangement and layout drawings will be necessary. Statements in the SAR that verify that the above conditions are met are acceptable. B. If there is a potential for explosive mixtures to exist, the MC is designed to withstand the effects of an explosion and instrumentation is provided to detect and annunciate the buildup of potentially explosive mixtures, dual instrumentation is provided to detect, annunciate, and effect control measures to prevent the buildup of potentially explosive mixtures, as outlined in SRP Section 11.3, subsection II,
