nate ways of meeting the General Design Criteria requirements (which are mandatbry). Any exceptions to the criteria are evaluated on an individual case basis; Exceptions are judged on the basis of the proposed design providing an equivalent level of safety and conservatism. A site visit should be performed before the evaluation findings are written for an OL. A site visit should include an audit verification that the design and layout criteria reviewed during the drawing review are implemented. An outline of topics for a site visit is provided in Appendix 7-B (Ref. 4) to SRP Chapter 7. In certain instances, it will be the reviewer's judgment that for a specific case under review, emphasis should be placed on specific aspects of the design, while other aspects of the design need not receive the same emphasis and in-depth review. Typical reasons for such a nonuniform placement of emphasis are the introduction of new design features or the utilization in the design of design features previously reviewed and found acceptable. However, in all cases, the review must be sufficient.to conclude conformance to the acceptance criteria, i.e., the requirements of the Commission's regulations. IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been submitted and the review supports conclusions of the following type, to be included in the staff's safety evaluation report: The review of systems required for safe shutdown included the processor to sensor coupling sensors, initiating circuitry, logic elements, inter- locks, redundancy features, and actuated devices, and that provide the .instrumentation and control functions that prevent the reactor from returning to criticality and provide means for adequate residual heat removal from the core, containment, and other vital components and systems. The staff concludes that the systems required for safe shutdown are acceptable and meet the relevant requirements of General Design Criteria 2, 4, 13, 19, 34, 35,
