es reliance on ECCS. 4. Task Action Plan Item II.K.3(10) of NUREG-0737 and NUREG-0718 which involves final recommendations by B&0 task force regarding applicant's proposal of use of anticipatory trips only at high power for selected plants. 5. Task Action Plan Item II.K.3(15) of NUREG-0737 and NUREG-0718 which involves isolation of HPCI and RCIC for BWR plants. 6. Task Action Plan Item II.K.3(18) of NUREG-0737 and NUREG-0718 involving ECCS outages for all plants. 7. Task Action Plan Item II.K.3(21) of NUREG-0737 and NUREG-0718 which involves a study evaluating restart of LPCS and LPCI after manual trip for BWR plants. 8. Task Action Plan Item II.K.3(39) of NUREG-0660 which involves evaluation of effects of water slugs in piping caused by HPI and CFT flows in B&W plants. In addition to the above criteria, the acceptability of the ECCS may be based on the degree of design similarity with previously approved plants. III. REVIEW PROCEDURES The procedures below are used during the construction permit (CP) review to assure that the design criteria and bases and the preliminary design as set 6.3-5 Rev. 2 - April 1984 forth in the preliminary safety analysis report meet the acceptance criteria given in subsection II of this SRP section. For operating license (OL) reviews, the procedures are utilized to verify that the initial design criteria and bases have been appropriately implemented in the final design as set forth in the final safety analysis report. The OL review also includes the proposed technical specifications to assure that they are adequate in regard to limiting conditions of operation and periodic surveillance testing. Much of the review described below is generic in nature and is not performed for each plant. That is, the RSB reviewer compares the ECCS design and param- eters to those of previously reviewed plants and then devotes the major portion of the review effort to those areas where the application is not identical to previously reviewed plants. The
