s to be performed, to levels in accordance with the requirements of 10 CFR 20.10320.1201, 20.1202, 20.1203, and 20.1204. The system shall be 64 designed so that filters containing radioactivity can be easily maintained and will not create an additional radiation hazard to personnel maintaining them, or those in adjacent occupied areas. Acceptability of the ventilation system, relative to radioactive gases and particulates will also be based on evidence that the applicant has applied the guidance of Regulatory Guide 8.8 or that acceptable alternatives have been proposed. Regulatory Guide 1.52, particularly Sections C.4 and 5, provides guidance that can be used in this review, although the guide is written with regard to mitigating accidents involving airborne radioactivity. Good practice in that regard is applicable to normal operation as well, since release of radioactivity in normal operational occurrences is usually different only in quantity from some of the accident cases. 4. AREA RADIATION AND AIRBORNE RADIOACTIVITY MONITORING SYSTEMS a. The area radiation monitoring systems will be acceptable if they meet the provisions of 10 CFR Part 20.10320.1201, 20.1202, 20.1203, and 20.1204,65 Regulatory Guide 8.15, Regulatory Guide 1.97 and NUREG-0737, Task Action Plan Item II.F.110 CFR Part 50, §50.34(f)(2)(xvii), and the following criteria: 66 12.3-11 DRAFT Rev. 3 - April 1996 1. Principal protection against intake of radioactive materials is provided by engineering controls. 2. The detectors are located in areas which may be normally occupied without restricted access and which may have a potential for radiation fields in excess of the radiation zone designations discussed in Section 12.3.II.1 of Reference 7the third paragraph under Item 1, above, FACILITY DESIGN FEATURES, in accordance with 67 ANSI/ANS-HPSSC-6.8.1. 3. The detectors provide on-scale readings of dose rate that include the design maximum dose rate of the radiation zone in which they are located as well
