Content:
The Human Factors Assessment Branch (HHFB) will be requested by ECGB to review any emergency procedures required to implement flood protection activities and warning times available for implementation thereof, based on the flood conditions identified in other sections.11 c. The Technical Specifications Branch (TSB) will be requested to confirm that an appropriate item is included in the plant technical specifications whenever emergency procedures are required to ensure adequate flood protection for the plant.12 For those areas of review identified as part of the primary responsibility of other branches, the acceptance criteria and methods of application are contained in the referenced SRP section.13 II. ACCEPTANCE CRITERIA HGEB ECGB acceptance criteria for this SRP section relate to the following regulations: 14 1. 10 CFR Part 50, 50.55a requires structures, systems, and components to be designed 15 and constructed to quality standards commensurate with the importance of the safety function to be performed. 2. General Design Criterion 2 (GDC 2) requires structures, systems, and components important to safety to be designed to withstand the effects of floods. 3. 10 CFR Part 100 requires, in part, that hydrologic characteristics be considered in the 16 evaluation of the site. Specific criteria necessary to meet the relevant flood protection requirements of 10 CFR Part 50, 50.55a, GDC 2, and 10 CFR Part 100 are as follows: 1. The flood design basis for each facility must be comparable with the positions in Regulatory Guide 1.59. For construction permit (CP) reviews, the types of flood 17 protection (discussed in Regulatory Guide 1.102) proposed must be capable of protecting those safety-related structures, systems, and components identified in Regulatory Guides 1.59 and 1.29. 2. For operating license (OL) or combined license (COL) reviews, the specific designs of 18 flood protection measures are reviewed to assure ensure the protection levels are 19 adequate (including
