he calculated core cooling performance after a LOCA conforms to critical criteria necessary to show that the core geometry will remain amenable to cooling and that long-term decay heat removal will be provided. 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 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. DRAFT Rev. 3 - April 1996 6.3-12 Much of the review described below is generic in nature and is not performed for each plant. That is, the RSB SRXB reviewer compares the ECCS design and parameters to those of 81 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 following steps are taken by the RSB SRXB reviewer to determine that the acceptance criteria of subsection II 82 have been met. These steps should be adapted to CP, or OL, or design certification reviews as 83 appropriate. 1. The relationship of the system under review to other previously approved plants is established. Systems or design features claimed to be identical or equivalent to those of previously approved plants are confirmed to be identical or equivalent. 2. Piping diagrams are reviewed to evaluate the functional reliability of the system in the event of single failures. That is, by referring to piping and instrumentation diagrams, the existence of the redundancy required by the
