January 1 - December 31, 2001 Docket Nos. 50-317/318 A maximum dose to any organ, in this case the GI-Tract, of 3.51 x 10-1 mrem to an adult for all pathways, which is about 1% of the acceptable dose limit of 25 mrem/year specified in 40 CFR 190.
Gaseous and Liquid Pathways Combined A maximum thyroid dose of 5.24 x 10-3 mrem via liquid and gaseous pathways, which is < 0.01% of the acceptable limit of 75 mrem/yr as specified in 40 CFR 190.
A maximum whole body dose of 9.82 x 10-3 mrem via liquid and gasxmus pathways which is < 0.1% of the acceptable limit of 25 mrem/yr as specified in 40 CFR 190.
A maximum calculated dose to all other organs via liquid and gaseous pathways was equal to 3.51 x10-1 mremn to the GI-Tract. This dose was about 1% of the allowable limit of 25 mrem/yr as specified in 40 CFR 190.
In all cases, the calculated doses are a small fraction of the applicable limits specified in 40 CFR 190. Therefore, it is concluded that the operation of Calvert Cliffs Units I & 2 produced radioactivity and ambient radiation levels significantly below the limits of Off-Site Dose Calculation Manual and 40 CFR Part 190. There was no significant buildup of radionuclides in the environment due to Calvert Cliffs.
