In reviewing the Exelon Generation Company, LLCs (Exelons) and AmerGen Energy Company, LLC (AmerGens) submittal dated August 15, 2006, related to a request to revise the emergency action levels (EALs), for the subject plants, the Nuclear Regulatory Commission (NRC) staff has determined that the following information is needed in order to complete its review.
The attached table provides the RAIs as it applies to each plant concerning the EAL discussed in Nuclear Energy Institute (NEI) 99-01, Revision 4, Methodology for Development of Emergency Action Levels. Exelon and AmerGen must address the RAIs on a site-specific basis. In addressing each of the RAIs applicable to Exelons and AmerGens sites, the responses should revise the EAL and/or provide more information in the EAL Basis, and revise the Difference/Deviation Matrix as applicable. A revised Difference/Deviation Matrix and Redline/Strikeout copy shall be provided in the response. In addition, a complete, clean, EAL Basis Document shall be provided as an attachment to the response.

How is a seismic event determined in ABN-38? Referencing procedures in the EAL does not allow for timely decision making in declaring an EAL. Provide the EAL threshold in a clear, concise manner in the body of the EAL in order to ensure timely decision making in declaring an EAL. (2.d)

X Provide additional justification for the inclusion of this seismic alarm EAL threshold (i.e., why instrumentation alone is not sufficient to declare the seismic EAL). In addition, does this annunciate in the control room, and is it reliable for indicating the EAL? If it does not, use the guidance in NEI 99-01. In addition, explain why there are limits, e.g., 0.01, referenced in some EALs and not in others.
