s for normal operation, including anticipated operational occurrences, based on expected amounts and concentrations of gaseous wastes over the life of the plant for each reactor on the site. The staff has determined that the proposed GWMS is capable of maintaining releases of radioactive materials in gaseous effluents such that the calculated individual doses in an unrestricted area from all pathways of exposure are less than 0.05 mSv (5 mrem) to the total body or 0.15 mSv (15 mrem) to the skin and less than 0.15 mSv (15 mrem) to any organ from releases of radioiodines, tritium, carbon-14, and radioactive materials in particulate form. B. The staff has determined that the calculated air doses from gaseous effluents at any location near ground level that could be occupied by individuals in unrestricted areas will be less than 0.01 cGy (10 millirads) for gamma radiation and 0.02 cGy (20 millirads) for beta radiation. C. Regarding Section II.D of Appendix I, the staff has considered the potential effectiveness of augmenting the proposed GWMS using reasonably demonstrated technology and determined that further gaseous effluent treatment will not effect reductions in cumulative population doses within an 80-km (50-mi) radius of the reactor at a cost of less than $1000 per man-rem or $1000 per man-thyroid-rem. 3. The applicant has met the requirements of 10 CFR 20.1302 since the staff has considered the potential consequences resulting from reactor operation with “1% of the operating fission product inventory in the core being released to the primary coolant” for a PWR, or “a fission product release rate consistent with a noble gas release rate to the reactor coolant of 3.7 MBq/sec per MWt (100 μCi/ sec per MWt) after 30 minute decay” for a BWR. The staff has further determined that, under these conditions, the concentrations of radioactive materials in gaseous effluents in unrestricted areas will be a small fraction of the limits specified in Table 2, Column 1,
