Emergency Action Level Development

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 have been endorsed by the NRC to aid in the development of a licensee-specific emergency action level scheme. The NRC encourages licensees, or future license applicants, to use the latest applicable endorsed document when developing an emergency action level scheme.

  • 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
  • NEI 99-01, "Development of Emergency Action Levels for Non-Passive Reactors" (Revision 6), Nuclear Energy Institute document.
  • NEI 07-01, "Methodology for Development of Emergency Action Levels, Advanced Passive Light Water Reactors" (Revision 0), Nuclear Energy Institute document.
