Docket No. 50-387/388 Hr. E. Nemethy Box 621 Bloomsburg, Pa.
17815 Dear Hr.
Nemethy:
Your tray 17, 1981 letter rega'r'ding the Pennsylvania Power and Light Company and Susquehanna Steam Electric Station has been fonvarded to the NRC for reply.
In your letter of flay 17, 1981, you expressed your concern for evacuation planninq associated with the Susquehanna Steam Electric Station.
Emer-qency P'lanning and tfanagement officials have defined a 10 mile radius from the reactor as the Emergency Planning Zone (EPZ).
This is the reqion over which the impact'of large atmospheric release of radioactivity could be very severe.
Early"evacuation of people from within this EPZ who would come under the radioactive plume is considered essential following an accident involving a large release of radioactivity.
However, depending upon weather conditions, the Emergency Planning authorities may evacuate persons at distances greater than 10 miles.
In addition, other protective actions over larger distances may be necessary.
These actions include:
(a) either complete denial of use (interdiction), or permitting use only at a sufficiently later time after appropriate decontamination of food stuffs such as crops and milk, b) decontamination of contaminated environment (land and property) when t is considered to be economically feasible to lower the levels of contamination to protective action guide levels, and (c) denial of use (interdiction) of contaminat~d land and property for varying periods of time until the contamination levels reduce to such values by radioactive decay and weathering so that'land and property can be economically decontaminated as in (b) above.
These actions would reduce the radio-logical exposure to the peopl'e from imoediate and/or subsequent use of or living in the contaminated"environment.
The radioloqical consequence=model used in Supplement 2 to NUREG 0564 was structured to account for 100Ã of radioactive material released in an accident, and the model assumed that a small fraction of it could be carried beyond 50 miles. However, the 500-mile figure quoted in the Supplement 2 should actually be 350 miles as has been now quoted in the Final'nviron-mental Statement.
