is housed in a structure whose design and design criteria have been reviewed by other branches (i.e., ASB SPLB , SGEB ECGB and 89 90 EMEB ) to assure that it provides adequate protection against wind, tornadoes, floods, 91 and missiles, as appropriate. 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.92 132. The reviewer checks the automatic and manual actions necessary for proper functioning 93 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 0718 (Ref. 1 and 11) . 94 95 143. 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) . For plants using a time delay for this 96 protection, the reviewer verifies that the design is consistent with staff positions in Generic Letter 83-02 (Reference 15) with regard to minimum and maximum expected response times. For plants which do not use a time delay for spurious isolation protection, the reviewer verifies that the applicant has provided proper justification for the design, and that the applicant's test program and test results demonstrate that the system meets the intent of II.K.3.15 in preventing spurious isolation of the RCIC system on initiation.97 154. The reviewer confirms, in conjunction with ASB SPLB as necessary, that the RCIC 98 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) . 99 165. The reviewer confirms per the
