nce testing is adequate. 11. The reviewer confirms that the RCIC is housed in a structure whose design and design criteria have been reviewed by other branches (i.e., ASB, SGEB, MEB) to assure that it provides adequate protection against wind, tornadoes, floods, and missiles, as appropriate. 5.4.6-6 Rev. 3 - April 1984 12. Upon request from the primary reviewer, other branches will provide input for the areas of review stated in subsection I. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. 13. The reviewer checks the automatic and manual actions necessary for proper functioning of the RCIC system (in conjunction with the HPCS or HPCI, the safety relief valves and the suppression pool cooling mode of RHR) for completeness and practicality when used for residual heat removal per the requirements of item II.K.1.22 of NUREGs-0737 and 0178 (Ref. 1 and 11). 14. The reviewer checks the RCIC system break detection provisions to see that the system is protected against spurious trip signals per the requirements of item II.K.3.15 of NUREGs-0737 and 0718 (Ref. 1 and 11). 15. The reviewer confirms, in conjunction with ASB as necessary, that the RCIC system can withstand a loss of offsite power to its support systems, including space coolers, for at least two hours per the requirement of item II.K.3.24 of NUREGs-0737 and 0718 (Ref. 1 and 11). 16. The reviewer confirms per the requirements of item II.K.3.13 of NUREGs-0737 and 0178 (Ref. 1 and 11) that analyses have been provided or referenced to determine the need to separate the RCIC and the HPCS (or HPCI) initiation levels. Based on these study results, the reviewer checks the RCIC design for appropriate provisions. In addition, the reviewer checks to see that automatic restart capability is provided for RCIC. 17. The reviewer checks (by calculation as necessary) to see that adequate net positive suction head is available for RCIC suction from all potential sources
