1 . ULNRC-06688, Request for License Amendment to Revise Technical Specifications to Adopt TSTF-505, Revision 2, Provide Risk-Informed Extended Completion Times RITSTF Initiative 4B, and TSTF-43 9, Revision 2, Eliminate Second Completion Times Limiting Time from Discovery ofFailure to Meet an LCO (LDCN 20-0007), dated October 21, 2021 (ADAMS Accession Number ML21294A394)

In the letter identified in Reference 1 , Union Electric Company (Ameren Missouri) submitted an application for amendment to Renewed Facility Operating License Number NPF-30 for the Callaway Plant. The requested amendment would revise applicable Technical Specifications to implement risk-informed Completion Times and establish the Risk-Informed Completion Time (RICT) Program in accordance with the guidance of TSTF-505, Revision 2. In support of the adoption of TSTF-505, TSTF-439, Revision 2, which involves the elimination of second Completion Times currently specified in the Technical Specifications, will also be adopted. In addition, the requested amendment would remove obsolete one-time Completion Times contained in the applicable Technical Specifications.

Subsequent to submittal of the Reference 1 license amendment request (LAR), it was identified that Attachment 3 of the EAR, which provided revised Technical Specification pages reflecting the proposed changes, contained errors. This discovery was verbally communicated from the NRC to Ameren Missouri, and upon confirming the errors, Ameren Missouri agreed to promptly provide a corrected Attachment 3 Accordingly, this letter provides a replacement version of Attachment 3, 83 15 County Road 459 : Steedman, MO 65077 : AmerenMissouri.com

This supplement to Ameren Missouris application involves no revision ofthe requested changes. As such, the information provided via this letter does not change the No Significant Hazards Consideration conclusions reached in the LAR, nor does it change the conclusion reached in regard to no need for an environmental assessment based on the categorical exclusion provisions of 10 CFR 51.22.

In accordance with 10 CFR 50.91 Notice for public comment; State consultation, Section (b)(l), a copy of this supplement provided in connection with the October 21 2021 amendment application is being provided to the designated Missouri State official.

Further, this submittal does not contain new commitments.
