with the combined license, the provisions of the Atomic Energy Act, and the NRC's regulations. SRP Acceptance Criteria Specific SRP acceptance criteria acceptable to meet the relevant requirements of the NRC’s regulations identified above are as follows for the review described in this SRP section. The SRP is not a substitute for the NRC’s regulations, and compliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. 5.4.8-5 Revision 3 - March 2007 1. The system should be capable of maintaining acceptable reactor water purity in normal operation and during anticipated operational occurrences, e.g., reactor startup, refueling, and condensate demineralizer breakthrough to ensure reactor coolant pressure boundary integrity in accordance with the requirements of GDC 14. The following should be included in the system design: A. The system should be designed to maintain reactor water purity within the guidelines provided in the latest version in the Electric Power Research Institute (EPRI) report series, “BWR Water Chemistry Guidelines,” and the technical specifications for water chemistry of reactor coolant systems for boiling water reactors. The system should provide demineralization of reactor water through mixed bed resins (beads or powdered) at approximately one percent of the main steam flow rate. B. The nonregenerative heat exchangers should be designed to reduce the temperature of cleanup flow to the demineralizer operating temperature when the regenerative heat exchanger cooling capacity is reduced as a result of partially bypassing a portion of the return flow to the main condenser or radwaste system. C. The RWCS should have the capability to permit
