Current review interface branch Changed review interface branch to Technical name and designation Specifications Branch (TSB). 24. Editorial Added EELB to "Review Interfaces" because a review was assigned them under REVIEW PROCEDURES, but there was no corresponding assignment under "Review Interfaces." 25. Integrated Impact 377 Added an interface to reflect new SRP Section 8.4 (proposed) covering overall review of station blackout issues. 26. Integrated Impact 1474 This review interface 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 an evaluation of containment integrity issues during shutdown and low- power conditions is conducted. Consideration of containment integrity 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. 27. Editorial Simplified for clarity and readability. SRP Draft Section 6.2.4 Attachment A - Proposed Changes in Order of Occurrence Item Source Description 6.2.4-27 DRAFT Rev. 3 - April 1996 28.
