DOCKET NUMBER 50-483 CALLAWAY PLANT UNIT 1 UNION ELECTRIC CO.
RENEWED FACILITY OPERATING LICENSE NPF-30 LICENSE AMENDMENT REQUEST TO REVISE CALLAWAY PLANT, UNIT 1 TECHNICAL SPECIFICATION 5.5.16, "CONTAINMENT LEAKAGE RATE TESTING PROGRAM," FOR PERMANENT EXTENSION OF TYPE A AND TYPE C LEAK RATE TEST FREQUENCIES (LDCN 2020-0004)
Pursuant to 10 CFR 50.90, Application for amendment of license or construction permit, Ameren Missouri (Union Electric Company) herewith transmits an application for amendment to Facility Operating License Number NPF-30 for the Callaway Plant. The proposed change revises Callaway Plant's Technical Specification (TS) 5.5.16, "Containment Leakage Rate Testing Program," to allow for the permanent extension of the Type A Integrated Leak Rate Testing (ILRT) and Type C Leak Rate Testing frequencies based on the guidance in NEI 94-01, " Industry Guideline for Implementing Performance-Based Option of 10 CFR 50, Appendix J," (Rev. 3-A).
Specifically, the proposed change will revise Callaway Plant's TS 5.5.16 by replacing the references to Regulatory Guide 1.163, "Performance-Based Containment Leak-Test Program," with a reference to NEI 94-01, Revision 3-A, dated July, 2012, and the limitations and conditions specified in NEI 94-01, Revision 2-A, dated October 2008, as the documents used to implement the performance-based containment leakage testing program in accordance with Option B of 10 CFR 50, Appendix J, "Primary Reactor Containment Leakage Testing for Water-Cooled Power Reactors."
The proposed amendment is risk-informed and follows the guidance in RG 1.174, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Licensing Basis," Revision 2.
The enclosure to this letter provides the evaluation of the proposed change and contains attachments that provide the evaluation of risk significance of permanent ILRT extension, the markup of the affected TS pages, and re-typed clean-copy TS pages.
