as unnecessary. 21. Editorial Inserted "water" because the focus is on water elevations rather than on structural elevations as in SRP Section 2.4 plans. 22. Editorial Deleted "including" and inserted "and examines" because "including" made no sense. 23. SRP-UDP format item Added interface for reviewing the site parameter envelope for a standard design certification per new 10 CFR Part 52. Renumbered the interfaces that follow. 24. Current SRB designation Changed SRB to ECGB. 25. Current PRB designation Changed PRB to SPLB. 26. Editorial This paragraph was created to separate primary reviews from coordinated reviews. 27. Current review branch designation Changed review interface branch to HICB. 28. Current review branch designation Changed review interface branch to EELB. 29. Current review branch designation Changed review interface branch to TSB. 30. Editorial A review interface is added to show that another branch has primary responsibility for identification of SSCs important to safety under SRP Sections 3.2.1 and 3.2.2. SPLB review of SSCs under this SRP section is provided to ensure protection of SSCs from flooding. 31. Integrated Impact 313 Added a review interface to the PRA review. The PRA is a TMI item and is required under 10 CFR 52.47. External and internal flooding contributes substantially to risk. This review interface also identifies reviews conducted to satisfy SECY 93-087 and ABWR FSER Staff guidance on Shutdown and Low Power Operations. The staff requested that design certification applicants complete an assessment of shutdown and low-power risk. The shutdown and low- power risk assessment must identify design-specific vulnerabilities and weaknesses and document consideration and incorporation of design features that minimize such vulnerabilities. In the shutdown risk analysis a separate flooding analysis that evaluates the flood protection provided by the plant during shutdown conditions is conducted. Consideration of the flooding analysis in the
