Content:
. Submit Proposed Change The evaluations performed to justify the proposed TS changes should be documented and included in the license amendment request submittal. The documentation should include the following: 1. A description of the TS changes being proposed and the reasons for seeking the changes, 2. A description of the process used to arrive at the proposed changes, 3. Traditional engineering evaluations performed, 4. Changes made to the PRA for use in the TS change evaluation, 5. Review of the applicability and quality of the PRA models for TS evaluations, 6. Discussion of the risk measures used in evaluating the changes, 7. Data developed and used in addition to the plant's PRA database, 8. Summary of the risk measures calculated including intermediate results, 9. Sensitivity and uncertainty analyses performed, 10. Summary of the risk impacts of the proposed changes and any compensating actions proposed, 11. A tabulation of equipment outage configurations that could threaten the integrity of the safety functions of the subject equipment and that are, or will be, prohibited by the TS or plant procedures (Tier 2). 12. A description of the capability to perform a contemporaneous assessment of the overall impact on safety of proposed plant configurations, including an explanation of how these tools will be used to ensure that risk-significant plant configurations will not be entered and that appropriate actions will be taken when unforeseen events put the plant in a risk- significant configuration (Tier 3). 13. A marked up copy of the relevant TS and Bases. The level of detail provided in the TS Bases should include adequate information to provide the technical basis for the revised AOT or STI. 14. All other documentation required to be submitted with a license amendment request. Rev. 0 - August 1998 SRP 16.1-20 IV.
