Content:
the requirements of Sections II.B, II.C, and II.D, of Appendix I to 10 CFR Part 50 are met with respect to exposures to radioactive materials and doses to the maximally exposed offsite individual. The criteria include dose limits from noble gases (as gamma and beta radiation air dose rates), radiation doses from carbon-14, tritium, particulates, and radioiodines, and the criterion in evaluating the results of a cost-benefit analysis in complying with ALARA provisions. 8. BTP 11-5 describes acceptable methods to evaluate doses at the EAB associated with the postulated releases of radioactive gases and radioiodines (as warranted) resulting from the failure of a gas storage tank or charcoal decay tank or a leak from a GWMS component. The BTP presents guidance 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 BWR-GALE Code (NUREG-0016) or PWR-GALE Code (NUREG-0017) and RG 1.112, with model parameters modified to reflect design features. If the results of a plant- and site-specific analysis do not meet BTP 11- acceptance criteria, the applicant should propose TS limiting the total amount of radioactivity in such components, as described in SRP Chapter 16, Section 5.5, Programs and Manuals, as adopted from standard technical specifications (NUREG-1430, NUREG-1431, NUREG-1432, NUREG-1433, and NUREG-1434). 9. 10 CFR 20.1301(e) requires that certain
