Dear Y~r. Pecora:
Thank you for your Aucpst 9, 1/79 letter.
Please be assured that your
" concerns are being considered prior to any decision to license the Susquehanna plant.
The NRC currently evaluates both the annual radiation
- dose astir}ated from the operNion of a nuclear plant-and the..potential life-long health impacts resulting fromm such exposures..
For example, pp. 4-12 through 4-2A )copy attached) of the DES for opera-tion of Susquehanna Units i and 2 (June 1979) describes,estitwtes of'the annual radinlogical impact of the t}(o units on indivi}duals living near the plant and on populationsI even hundreds of @iles distant.
Those ipacts, expressed in teri}s of if&time dose cosr>ihnents, are -coa~pared >>ith Ne natural background radiation exposure rate. En addition, using the 1ifetime cancer mortality risk estimators on p. C-27, the risk of'ancer nortalitv associated -}}arith the'stimated annual doses is shown in the folloI,ring,bible.
