not exceed the values specified in Table 2 of Appendix B to 10 CFR Part 20. B. That the annual and hourly doses from external sources to an individual continuously present in an unrestricted area will not exceed 0.5 mSv (0.05 rem) and 0.02 mSv (0.002 rem), respectively. Meeting the above requirements provides assurance that the dose limits to individual members of the public specified in 10 CFR 20.1301 will not be exceeded. The review detailed in this SRP section will evaluate the ability of the system to meet the dose requirements identified above. SRP Section 11.2 identifies compliance with the limits on liquid effluent concentrations in unrestricted areas as an acceptance criterion; consequently, the ability of a facility to meet this criterion will be evaluated under Section 11.2. 11.3-10 Revision 3 - March 2007 2. Under the provisions of 10 CFR 20.1406, the NRC focuses on design features or operational procedures that would reduce the amount of gaseous wastes, reduce radioactivity levels and discharges of radioactive materials in effluents, minimize contamination of the facility and environment, and avoid or reduce the potential for uncontrolled and unmonitored releases to the environment. In the context of this SRP section, relevant and specific guidance to meet 10 CFR 20.1406 includes: A. Gaseous waste processing systems (either as permanently installed systems or in combination with mobile equipment) with a potential for leakage should include the means to control and contain this leakage to prevent contamination of building floors and interconnected systems (e.g., curbing, floor sloping to local drains, floor-to-floor seals over floor expansion joints, wall-to-floor joint seals, sheathed hoses, drip pans or containment boxes, backflow preventers, siphon breakers, self-sealing quick-disconnects, and operational interlocks). See guidance given in IE Bulletin No. 80-10 as an example. B. In minimizing the generation of waste, provisions should be made to clean
