ide backup provisions for grab sampling. If the provisions do not address post-accident sampling, refer instead to the “Notice of Availability for Referencing in License Amendment Applications Model Safety Evaluation on Technical Specification Improvement to Eliminate Requirements on Post Accident Sampling Systems Using the Consolidated Line Item Improvement Process.” Under this notice, the applicant must do the following: A. Maintain contingency plans for obtaining and analyzing highly radioactive samples of reactor coolant, containment sump, and containment atmosphere. B. Maintain a capability for classifying fuel damage events at the Alert Level threshold (typically at the 300 microcuries per milliliter (uCi/mL) iodine dose equivalent). C. Maintain the capability to monitor radioiodines that have been released to offsite environs. 8. 10 CFR 20.1301(e) requires that facilities licensed by the NRC comply with the U.S. Environmental Protection Agency’s (EPA) generally applicable environmental radiation standards of 40 CFR Part 190 for facilities that are part of the fuel cycle. The EPA annual dose limits are 0.25 millisievert (mSv) (25 millirem (mrem)) to the whole body, 0.75 mSv (75 mrem) to the thyroid, and 0.25 mSv (25 mrem) to any other organ. Meeting the requirements of 10 CFR 20.1301(e) requires the consideration of all potential sources of external radiation and radioactivity, including liquid and gaseous effluents, external radiation exposures from buildings, storage tanks, radioactive waste storage areas, and N-16 skyshine from BWR turbine buildings. The EPA standards apply to the entire site or facility, which may have either single or multiple units. SRP Sections 11.2, 11.3, and 11.4 address sources of radioactivity and doses associated with liquid and gaseous effluents and solid wastes. SRP Section 12.3-12.4 addresses sources of radiation and external radiation exposures from buildings, storage tanks, radioactive waste storage areas, and N-16
