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.
