specified in Sections II.B and II.C, and the acceptance criterion for cost-benefit analysis specified in Section II.D for meeting the as low as reasonably achievable objective will be met. 8. BTP 11-5 describes acceptable methods to evaluate doses associated with the postulated releases of radioactive gases resulting from the failure of a gas decay tank or bed or a leak from a GWMS component. The BTP presents guidelines for selecting the type of failure and model assumptions that provide reasonable assurance that the radiological consequences of a single failure of an active component will not result in doses exceeding a small fraction (10 percent) of the 10 CFR Part 100 dose limits for the whole body to any offsite individuals for the postulated event of systems designed to withstand explosions and earthquakes, or 1 mSv (0.1 rem) for systems not designed to withstand explosions and earthquakes. The analysis assumes that the waste gas system fails to meet its design bases, as required by 10 CFR 50.34a and GDC 60 and 61. The analysis relies on methods described in BTP 11-5 and the use of the PWR-GALE or BWR GALE code (NUREG-0016 or NUREG-0017) and Regulatory Guide 1.112. 9. 10 CFR 20.1301(e) requires that NRC-licensed facilities comply with the 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 mSv (25 mrem) to the whole body, 0.75 mSv (75 mrem) to the thyroid, and 0.25 mSv (25 mrem) to any other organ. 10 CFR 20.1301(e) requires that all potential sources of external radiation and radioactivity be considered, including liquid and gaseous effluents and 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, whether with single or multiple units. SRP Sections 11.2 and 11.4 address the 11.3-13 Revision 3 - March 2007
