re. The reviewer of reactor thermal hydraulic systems then evaluates the RHR system description to determine that the RHR system design allows for this maximum temperature. 5.4.7-11 Revision 4 - March 2007 11. The reviewer of reactor thermal hydraulic systems contacts the reviewer of instrumentation and control systems to obtain any needed information from that review. Specifically, the reviewer of instrumentation and control systems confirms that automatic actuation and remote-manual valve controls are capable of performing the functions required, and that sensor and monitoring provisions are adequate. The instrumentation and controls of the RHR system must have sufficient redundancy to satisfy the single failure criterion. 12. The reviewer of reactor thermal hydraulic systems contacts the reviewer of containment integrity to exchange information related to their reviews. 13. The reviewer of reactor thermal hydraulic systems contacts the reviewer of the quality assurance and maintenance to discuss any special test requirements and to confirm that the proposed preoperational test program for the RHR system is in conformance with the intent of Regulatory Guide 1.68. 14. The reviewer evaluates the proposed plant technical specifications as follows: A. Confirm the suitability of the limiting conditions of operation, including the proposed time limits and reactor operating restrictions for periods when system equipment is inoperable because of repairs and maintenance. B. Verify that the frequency and scope of periodic surveillance testing is adequate. 15. The reviewer contacts the reviewers of structural analysis and seismic/geotechnical issues to confirm that the systems employed to remove residual heat are housed in a structure whose design and design criteria provide adequate protection against wind, tornadoes, floods, and missiles, as appropriate. 16. For PWRs, the reviewer confirms that the auxiliary feedwater supply satisfies the requirements of Branch Technical
