Introduction This appendix describes an acceptable approach for setting a plume exposure EPZ size based on determining the area within which public dose, as defined in 10 CFR Part 20, “Standards for Protection Against Radiation,” Section 20.1003, “Definitions,” is projected to exceed 10 millisieverts (mSv) [1 roentgen equivalent man (rem)] total effective dose equivalent (TEDE) over 96 hours from the release of radioactive materials, resulting from a spectrum of accidents credible for the facility. This approach has been generalized from the dose assessment methodologies that informed EPZ size determinations in NUREG-0396, “Planning Basis for the Development of State and Local Government
