On August 12, 2016, Union Electric Company (dba Ameren Missouri) received a Notice of Violation (NOV) identified for the Callaway Plant (Reference 1). Ameren Missouri's 30-day response to the NOV was provided in Reference 2, and the NRC's review and acknowledgement of the response to the NOV was provided in Reference 3.

In Reference 2, Ameren Missouri committed to perform an Essential Service Water (ESW) system transient analysis and identify non-conforming structural components by April 30, 2017. Further, a supplemental response identifying actions required as a result of the transient analysis was committed to be provided by June 30, 2017. This letter communicates that the preliminary results of the transient analysis are still being finalized such that the final analysis will not be completed by the end of April.

Therefore, it can be expected that the ESW transient analysis will be completed and the supplemental response identifying actions will be provided by June 30, 2017.

This letter does not contain new commitments.
