3) Technical Specifications Task Force Letter TSTF-12-09 "Correction to TSTF-510-A, Revision 2, 'Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection"' dated March 28, 2012 (Accession No. ML12088A082)

On March 9, 2015, pursuant to 10 CFR 50.90, Union Electric Company (Ameren Missouri) transmitted a request (Reference 1) for revising the Technical Specifications in order to adopt TSTF-510, "Revision to Steam Generator Program Inspection Frequencies and Tube Sample Selection,"

using the Consolidated Line Item Improvement Process (CLIIP). Subsequent to submittal of the license amendment request, it was identified that some wording was inadvertently omitted from the text of the proposed revision of Technical Specification (TS) 5.5.9, "Steam Generator (SG) Program."

This omission, as well as some additional minor inconsistencies with TSTF-510 and other minor errors of a typographical or editorial nature were corrected and re-submitted in Reference 2.

Subsequent to the Reference 2 submittal, an additional administrative inconsistency was identified in the text of the proposed revision of Technical Specification (TS) 5.5.9, "Steam Generator (SG)

Program." Specifically, in TS 5.5.9.d.2, the word "repair" in the sentence including the words" ... and that may satisfy the applicable tube repair criteria ... " should be replaced with the word "plugging," so that this sentence should properly read" ... and that may satisfy the applicable tube plugging criteria .... " This administrative inconsistency was previously identified by the Technical Specifications Task Force (Reference 3) but was overlooked in the Reference 1 and Reference 2 submittals. Accordingly, the affected pages of Attachment 1, "Technical Specification Page Markups," and Attachment 2, "Retyped Technical Specification Pages," as provided in the Reference 2 submittal, are hereby revised and re-submitted as Attachments 1 and 2 to this letter, respectively.

Correcting this error requires a change to be made to what was proposed to be changed in the Technical Specifications, as presented in Attachments 1 and 2 of the Reference 2 submittal. The Callaway Onsite Review Committee has therefore reviewed and approved the change proposed in this supplement to the amendment request (i.e., the word change within proposed insert forTS 5.5.9.d.2) and has approved the submittal thereof. In addition, in accordance with 10 CFR 50.91 "Notice for public comment: State consultation," Section (b)(l), a copy of this supplement to the amendment application is being provided to the designated Missouri State official.

This supplement to the amendment request involves no changes to the 10 CFR 50.92 (Basis for No Significant Hazards) evaluation or the environmental evaluation provided in Reference 1, nor does it contain new commitments. If there are any questions regarding this submittal, please contact Mr. Tom Elwood at 314-225-1905.
