GQA submittal includes the QA program change required by 10 CFR 50.54(a)(3)(ii), accompa- nied by the supplemental information described in Regulatory Position 4.1.2 of this guide, which will be used by the staff to determine the acceptability of the program. A licensee may elect to categorize a limited number of plant systems and apply GQA controls to these selected plant systems. The SSCs included in the bounding analysis discussed in Regulatory Position 2.2 determine which SSCs are candidates for categorization. If all SSCs in the PRA are included in the bounding analysis, all SSCs may be candidates for categorization. The licensee identifies the systems to be categorized in the supplemental information. The licensee can choose when to categorize each system and may choose not to categorize all the systems identified in the submittal. If categorization of systems not included in the supplemental information proves desirable, the - I s 2. Perform 4.

SSCs that should be considered as potential candidates include: " Systems and components that are subject to current QA requirements in Appendix B to 10 CFR Part 50, " SSCs modeled in the PRA for the plant, • Non-safety-related SSCs that are within the scope of the Maintenance Rule (10 CFR 50.65), and " Non-safety-related equipment that has previously received augmented quality treatment (e.g., anticipated transient without scram, station blackout, fire protection). The licensee should ensure that the QA program commitments and other QA-related information germane to the contemplated changes in QA practices are clearly understood and adhered to, unless modified or amended through the appropriate licensing or regulatory actions.
