e plant configurations; discussion of how these plant configurations will be prohibited (e.g., by TS or plant procedures) during the TS outage; discussion of any compensatory measures proposed as part of the TS change evaluation; presentation of the risk impact of these compensatory measures either quantitatively or qualitatively (Regulatory Position C.2.3.6, Tier 2), (6) capability of the risk-informed plant configuration control program to perform contemporaneous assessments of the overall impact on safety of proposed plant configurations, including an explanation of how these tools or other processes will be used to ensure that risk-significant plant configurations will not be entered and that appropriate DG-1287, Page 25 actions will be taken when unforeseen events put the plant in a risk-significant configuration (Regulatory Position C.2.3.7, Tier 3), (7) risk measures used in evaluating the proposed TS changes, providing the calculated risk measure values associated with the TS change evaluation (including intermediate results) and discussing how they align with the risk-acceptance guidelines presented in this RG in addition to those in RG 1.174, as applicable; if the risk metrics approach or slightly exceed the acceptance guidelines, address the additional aspects of plant risk and operation identified in Section C.2.6 of RG 1.174 (Regulatory Position C.2.4), and (8) comparison of the risk of available alternatives, as applicable (Regulatory Position C.2.5). g. the integrated decision to determine final acceptability of the proposed TS change (Regulatory Position C.2.6), h. implementation and monitoring program (Principle 5), including use of the Maintenance Rule program (10 CFR 50.65) (Regulatory Position C.3, Element 3), i. a marked-up copy (e.g., redline markup) of the relevant TS and bases, including adequate information to provide the technical basis for the revised CT or SF, and j. all other documentation required to be submitted with a license
