4. DRAFT Rev. 2 - April 1996 4.6-4 9. For new BWR plant applicants, the Control Rod Drive System (Control Rod Drive Pump) may be included in the systematic assessment of shutdown risks as an alternate feature that can provide core inventory makeup in the event of a loss of normal decay heat removal. The Probabilistic Safety Assessment Branch (SPSB) coordinates and performs the shutdown risk assessment reviews as part of its primary review responsibility for SRP Section 19.1 (proposed).46 For those areas of review identified above as being reviewed as part of the primary review the responsibility of other branches, the acceptance criteria and their methods of application are contained in the referenced SRP sections of the corresponding to those primary branches.47 II. ACCEPTANCE CRITERIA Acceptability of the information presented in Section 4.6 of the applicant's safety analysis report (SAR), including related sections, is based on meeting the general design criteria. The acceptance criteria for the areas of review are the following: 1. General Design Criterion 4, "Environmental and dynamic effects design bases," as related to the environmental conditions caused by high or moderate energy pipe breaks during normal plant operation as well as postulated accidents.48 21. General Design Criterion 23, "Protection System Failure Modes," as related to failing into a safe state. 32. General Design Criterion 25, "Protection System Requirements for Reactivity Control Malfunctions," as related to the functional design of redundant reactivity systems to assure that specified acceptable fuel design limits are not exceeded for malfunction of any reactivity control system. 43. General Design Criterion 26, "Reactivity Control System Redundancy and Capability," as related to the capability of the reactivity control system to regulate the rate of reactivity changes resulting from normal operations and anticipated operational 49 occurrences. 54. General Design Criterion 27, "Combined
