Each operating nuclear power plant is required to include in its emergency plans a standard emergency classification and EAL scheme. An EAL is a pre-determined, site-specific, observable threshold for a plant condition that places the plant in an emergency class. The NRC is using an FAQ process to assist licensees with EAL development. As such, a practical knowledge of existing EAL regulatory guidance is required in applying any EP FAQ response.

Regulatory Guidance

The following documents provide guidance for (1) developing or changing a standard emergency classification and action level scheme and (2) assisting licensees in determining whether to seek prior NRC approval of deviations from the new guidance.

Regulatory Guide 1.101 (Revision 4), "Emergency Response Planning and Preparedness for Nuclear Reactors" endorses the following documents as alternative methods for developing EALs:

Appendix 1 to NUREG-0654/FEMA-REP-1, "Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants" (November 1980)
NUMARC/NESP-007, "Methodology for Development of Emergency Action Levels" (Revision 2, January 1992), Nuclear Utilities Management Council document
NEI 99-01, "Methodology for Development of Emergency Action Levels" (Revision 4), Nuclear Energy Institute document
NEI 99-01, "Methodology for Development of Emergency Action Levels" (Revision 5), Nuclear Energy Institute document

Regulatory Issue Summary (RIS) 2003-18, "Use of NEI 99-01, 'Methodology for Development of Emergency Action Levels'" (Revision 4, January 2003)
Supplement 1 to RIS 2003-18
