cific DCD (as defined in Section II of the DCR) that is maintained by the applicant or licensee. For this reason, this information remains subject to the Tier 2* change process. Changes to Operational Requirements In some cases, an operational requirement may be completely reviewed and approved as part of the DC rulemaking such that it is not reviewed by the NRC staff in the COL proceeding. Generic technical specifications (except for the COL action items - bracketed values and bracketed site-specific information) are an example of these operational requirements. Another example could be an operational program that is “fully described” in the generic DCD and approved by the staff in the context of approving the design of an SSC described in the generic DCD. For this category of information, a COL applicant intending to change this information should request an exemption, as described in Section VIII.C of the DCRs. The Commission may grant such a request only if it determines that the exemption will comply with the requirements of 10 CFR 52.7. It is advantageous for the generic DCD, COLA, and associated SE reports to clarify which information is considered an operational requirement within this category of information. COL applicants should also be aware that, in a COL proceeding, the Commission may change operational program elements that were completely reviewed and approved in a DCR. If this change also involves a change to a design feature in the generic DCD, then the requirements of 10 CFR 52.63 apply. If a change to a design feature in the generic DCD is not involved, the Commission will not make generic changes to such operational requirements unless the standards of 10 CFR 50.109, “Backfitting,” are met and will not make plant-specific changes to such requirements unless the standards of 10 CFR 2.335, “Consideration of Commission Rules and Regulations in Adjudicatory Proceedings,” are met.
