Dear Mr. Grier:
Eubject: Calvert Cliffs Nuclear Power Plant Units No. 1 and 2.
License Nos. DPR-53 and 69 Nonroutine Radiological Enviren= ental Operating Report.
This report is sub=itted, in duplicate, to ec= ply with the require-ments of Appendix B Environ = ental Technical Specifications Section 5.6.2.b.
The Oyster sa=ples were collected en August 27, 1979 frc= the C;=p-Coney sa pling locatien and analyzed for ga--a-emitting radionuclides as required.
The results of the analyses showed the presence of Ag-110 at 266* h% pCi/Kg(vet).
The cyster sa=ples collected en the same date frc= the K nwood Beach sa=pling location (the background locatien) sheved Ag-llc = at e
$ hpCi/Kg(vet).
A review of the available effluent release data indicates that Ag-100 = in oysters is plant related.
Based on the observed levels of Ag-10C= during August 1979, for an average adult consu=ing ene kilogra of oysters per year the doses to the GI Tract and Whcle Ecdy are estimated at v 1.6x10-2 =re=/ year and.v 2.3x10 -5
=re / year, respectively.
These are very s-n'l fractions of the allevable 25 =re=/ year (GI Tract) and 25 =re=/ year (Whole 3cdy) deses to =e=bers of the general public, (L0 CFR Part 190 Environ = ental Radiation Protection Standards for Nuclear Power Operations) and are considered to be of no consequence to the health and safety of the public.
Very truly yours, L _ '.t J. W. Stout, Jr.
