By letter dated August 27, 2009 (Reference 1), NRC transmitted a number of requests for additional information (RAIs) regarding the Union Electric Company (AmerenUE) response to Generic Letter (GL) 2004-02. The NRC requested a response to the RAIs prior to November 25, 2009. AmerenUE subsequently participated in a public meeting with the NRC on November 20, 2009 (per Reference

2) to discuss the RAIs. The meeting discussions focused on how the RAIs would be addressed and closed, as well as the fact that some would remain open due to issues to be resolved in the near future (2010).
