included in the ABWR FSER risk assessment as a system that can provide alternative core inventory capability in the event of the loss of normal decay heat removal. Consideration of this system in the shutdown and low-power risk assessment is the responsibility of the SPSB and will be included in the proposed SRP Section 19.1 on risk assessments. 47. SRP-UDP format item, editorial This is an editorial change to modify the concluding statement of the Review Interfaces section so that it is consistent with the format of the SRP-UDP program. 48. Integrated Impact #1418. Added GDC 4 as acceptance criteria to support review procedure item III.2 which describes a review verifying that the control rod drive systems is protected against the effects of postulated pipe break accidents. 49. SRP-UDP format item. Added normal operations to be consistent with GDC 26. Added the word "anticipated" to be consistent with the SRP update guidance. 50. Editorial. This is an editorial change to add the phrase "reliably control reactivity changes to assure the capability to" to the description of General Design Criteria 27. This more fully describes the capability of the reactivity control systems and emergency core cooling systems and is consistent with the wording in Appendix A to 10 CFR 50. 51. SRP-UDP format item. Replaced the word "events" with "operational occurrences" to be consistent with the SRP update guidance. 52. Integrated Impact #564. 10 CFR 50.62 was added to the acceptance criteria to address the requirements for the reduction of risk from anticipated transients without scram events for light water nuclear reactors. The application of this requirement to this SRP section is limited only to those aspects that have a direct impact on the functional design of the control rod drive systems.
