47 DRAFT Rev. 4 - April 1996 5.4.6-6 must satisfy the single failure criterion in this regard. In addition, the RCIC system is to perform its function without the availability of any a-c power per the requirements of General Design Criterion 34 (Ref. 2), and in conjunction with HPCS, (or HPCI, or 48 HPCF ) must be designed to assure an extremely high probability of accomplishing its 49 safety function as required by General Design Criterion 29 (Ref. 6).50 4. As a system which must respond to certain abnormal events, the RCIC system must be designed to seismic Category I standards (discussed in SRP Section 3.2.1) and must not be shared among nuclear power units except as permitted by General Design Criterion 5 (Ref. 7).51 5. The RCIC and HPCS, (or HPCI, or HPCF ) systems must be protected against natural 52 phenomena, external or internal missiles, pipe whip, and jet impingement forces so that such events cannot fail both systems simultaneously. Acceptance criteria for these are discussed in SRP Sections 3.3.1 through 3.6.2. Acceptance criteria for RCIC instrumentation are described in SRP Section 7.4.53 6. The RCIC system must meet the requirements of General Design Criterion 54 (Ref. 8)54 with regard to leak detection and isolation provisions for lines passing through the primary containment. Other containment isolation criteria for RCIC are described in SRP Sections 6.2.4 and 6.2.6. 7. The RCIC system must meet the recommendations of Task Action Plan items II.K.1.22, II.K.3.13, II.K.3.15, II.K.3.22, II.K.3.24, and III.D.1.1 of NUREG-0737 (Ref. 1) and NUREG-0718 (Ref. 11) with regard to actions needed for operation, system initiation setpoint and automatic restart capability, break detection provisions, automatic suction switchover to the suppression pool, adequacy of space cooling, and leakage minimization, respectively.55 7. The RCIC system must meet the following Task Action Plan item recommendations of 56 NUREG-0737 and NUREG-0718 (References 13 and 12) : 57 a.
