DOCKET NUMBER 50-483 CALLAWAY PLANT UNIT 1 UNION ELECTRIC CO.

FACILITY OPERATING LICENSE NPF-30 REQUEST TO CORRECT TYPOGRAPHICAL ERROR IDENTIFIED IN TECHNICAL SPECIFICATION 3.1.9 REQUIRED ACTION A.3 The purpose of this letter is to request action for correction of a typographical error identified in Technical Specification (TS) 3.1.9, "RCS Boron Limitations< 500°F," ofthe Callaway Technical Specifications. The error is that the"?:" symbol is incorrectly displayed as "S" in front ofthe value for the reactor coolant system (RCS) cold leg temperature limit specified in Required Action A.3. As explained below, the error occurred in connection with the issuance of Amendment 202 to the Callaway Operating License TS 3 .1. 9 was added to the Technical Specifications via License Amendment 174 which was issued and implemented in 2006. As intended, the "?:" symbol was present in Required Action A.3 at that time.

No subsequent TS changes were made such that they would have directly affected TS 3.1.9 until the processing and issuance of Amendment 202. In that regard, it was recently determined that the "?:"

symbol was inadvertently changed from a symbol character to a text character with the issuance of Amendment 202 in July 2011. Amendment 202 extensively revised the Technical Specifications by relocating specific surveillance frequencies to a licensee controlled program such that a significant amount of text was inserted into and removed from many TS sections. Due to the text changes, the amendment required issuing additional revised TS pages due to re-pagination.

In the software used for the Callaway Technical Specifications, Character Tags are used to change the look of text and to ensure that the documents are formatted consistently. ForTS pages that are incorporated into the amendment because of re-pagination, the existing revision bar Character Tags are removed and a new revision bar is added to the footer to show that the change to the page is due to page re-numbering. It appears that during Amendment 202, the symbol Character Tag for Required Action A.3 was inadvertently removed with the removal of the revision Character Tags on this page.

ULNRC-05883 July 12, 2012 Page 2 Due to the volume of pages required to be issued for Amendment 202, this error was not identified in the review that was conducted prior to transmitting the clean typed pages to the NRC for issuance of the amendment.

In order to correct the problem of the missing"~" in Required Action A.3, Ameren Missouri is hereby providing (in the enclosure to this letter) a corrected, clean copy ofpage 3.1-22 (with Amendment No.

202 indicated on the page) for use in re-issuance of the corrected page. This will enable the NRC to re-issue a corrected TS page 3.1-22 for License Amendment 202, reflecting the corrected symbol in front of the value for the RCS cold leg temperature specified in Required Action A.3.

It should be noted that a review of the Amendment 202 issued pages and of the current Technical Specifications did not identify any additional issues with symbol Character Tags in the TS documents.

This letter contains no new commitments. Please contact Tom Elwood, Supervising Engineer, Regulatory Affairs and Licensing at 314-225-1905 for any questions you may have regarding this submittal.

Sincerely,
