pplicant will provide portable continuous air monitors when needed to monitor air in areas not provided with fixed airborne radioactivity monitors. All airborne and area radioactivity monitors will be calibrated periodically. [List examples of other airborne radioactivity monitoring features] The objectives and location criteria of [plant name] area and airborne radiation monitoring systems are in conformance with those portions of 10 CFR 20.1501; 10 CFR 50.34, 10 CFR 52.47, or 10 CFR 52.79; and 10 CFR 50.68 or 10 CFR 70.24, as well as RG 1.97, BTP 7-10and RG 8.8, related to radiation and airborne radioactivity monitoring. The objective of the applicant’s accident radiation monitoring system is to provide the capability to assess the radiation hazard in areas that may be occupied during the course of an accident. The installed instruments have emergency power supplies, and the portable instruments are placed to be readily accessible to personnel responding to an emergency. The systems are designed for use in the event of an accident in terms of usable instrument range, with appropriate margins for the accident source term and the environment the instrument can withstand, and meet the provisions of 10 CFR 50.34(f)(2)(xvii), Item II.F.1(3) of NUREG-0737, and RG 1.97. Instrumentation to monitor plant areas where fuel is handled and stored meets the criteria of 10 CFR 50.68 or 10 CFR 70.24 and GDC 63 in Appendix A to 10 CFR Part 50 and is acceptable. The applicant provided a dose assessment, as described in RG 8.19, including a completed summary table of occupational radiation exposure estimates, sufficient detail to explain the performance of the assessment process, a systematic process for considering and evaluating dose-reducing changes in design and operations as part of the comprehensive ongoing design reviews and a record of the review procedures, documentation requirements, and identification of principle ALARA-related changes resulting from the dose
