The Protective Action Recommendations (PAR) project provides an evaluation of alternative protective actions that could potentially reduce consequences during a severe radiological emergency at a nuclear power plant. The study included an assessment of alternative protective actions within a range of evacuation times and calculated public health consequences for these alternative protective actions. PARs identified in this report will aid in the determination of whether improvements or changes to the Federal guidance contained in NUREG-0654/FEMA-REP-1, Supplement 3 (NRC, 1996) would be beneficial. Early and staged evacuations provide alternative protective actions that have the effect of moving the public away from the source term in an expeditious manner. Many off-site response organizations already institute some level of early protective actions at a Site Area Emergency such as the movement of school children. Expanding on this concept with staged evacuations may reduce potential consequences and may better protect public health and safety under specific conditions. The effectiveness of the protective action strategy is sensitive to both initial release timing and the evacuation time, and therefore, it is important to reduce the uncertainties associated with each of these parameters. Volume I of this NUREG / CR provides the technical analyses of alternative protective actions. Volume II of this NUREG / CR will include a detailed assessment of the anticipated public response.
