lysis, augmented by a discussion of the nonquantified aspects of the GQA program that are expected to provide a safety benefit. The scope, in terms of systems included in the bounding analysis, should be discussed. If the bounding analysis was performed on a limited number of systems, the systems should be clearly identified. (4) A description of the licensee process to ensure PRA quality, a discussion as to why the PRA is of sufficient quality to support the categorization process, and the results of all peer or industry reviews of the PRA. (5) Applicable documentation discussed in Section 3.3, "Cumulative Risk," of Regulatory Guide 1. 174 (Ref. 3). (6) A description of how the proposed change impacts any licensee commitments. 4.2 Plant Data and Engineering Evaluation Licensees may submit the following information as a separate document to support the proposed GQA submittal. This information should be available for staff review at the licensee's offices. 4.2.1 Systems Pertinent to GQA Summarize design and operating features of systems in which changes to the QA program are planned, as well as systems supported by the systems in which changes to the QA program are planned. For each system, include a table summarizing the key design and operating data. Values that are used in the analysis should be identified and justified. Refer to appendices or other documents (e.g., specific sections of the FSAR or design basis documents) as necessary for more details. Systems to be considered should include the pertinent portions of all systems modeled in the plant-specific probabilistic analysis. 4.2.2 Status of SSCs All SSCs whose QA program control is proposed to be changed should be listed and should include (at a minimum) the plant's SSC label, the current QA categorization (by default all safety-related SSCs will initially have a "high" QA categorization), the proposed QA categorization, associated correlation with system functions, and a brief explanation of the
