ULNRC-06052 November 26,2013 Page2 On March 12, 2012, the Nuclear Regulatory Commission (NRC) issued a request for information (Reference 1). The letter requested licensees to conduct seismic hazard walkdowns to verify current plant configuration with the Current Licensing Basis (CLB). The NRC endorsed an Electric Power Research Institute (EPRI) guidance document (Reference 2), because the NRC staff determined that the use of the guidance, coupled with appropriate training, would meet the objectives and requests of the 50.54(f) letter.

By letter dated November 27, 2012 (Reference 3), Ameren Missouri responded to the information request for the Callaway Plant. On November 1, 2013, the NRC requested Ameren Missouri to provide additional information regarding seismic walkdowns (Reference 4). Enclosure 1 contains Ameren Missouri's response to Reference 4 for Callaway Plant. Please note that the date for Callaway's Refueling Outage 20 has moved from 10/4/2014 to 10/1112014.

This letter contains no new regulatory commitments.

If you have any questions regarding this submittal, please contact Scott Maglio, Regulatory Affairs Manager.

I declare under penalty of perjury that the foregoing is true and correct.
