rsonnel have the capability to assess the radiation hazard in areas that may be accessed during the course of an accident, in accordance with the criteria of 10 CFR 50.34(f)(2)(xvii); NUREG-0737, Item II.F.1; and RG 1.97, Revision 4. ii. Portable instruments to be used in the event of an accident should be placed so as to be readily available to personnel responding to an emergency. iii. Emergency power should be provided for installed accident monitoring systems. iv. The accident monitoring systems should have usable ranges that include the maximum calculated accident levels and should be designed to operate properly in the environment caused by the accident. v. Two high-range radiation monitors are provided in containment in accordance with the requirements of 10 CFR 50.34(f)(2)(xvii) and Item II.F.1 of NUREG-0737. D. Appendix A to RG 1.21 provides useful guidance about effluent monitoring that applies to the acceptability of in-plant airborne radioactivity monitoring. RG 8.2 includes guidance on surveys to evaluate radiation hazards. The detailed guidance in ANSI N13.1-1999 covers the sampling of airborne radioactive materials in ventilation ducts and stacks of nuclear facilities and may be used for acceptance criteria on the actual sampling process and certain techniques involved. RG 8.8 provides further guidance on monitoring systems. E. Instrumentation for monitoring areas where reactor fuel is stored or handled will be acceptable if it meets the criteria of 10 CFR 50.68. 5. Dose Assessment The dose assessment will be acceptable if it documents in appropriate detail the assumptions made, calculations used, results for each radiation zone (including numbers and types of workers involved in each), expected and design dose rates, and projected person-Sievert (person-rem) doses, in accordance with RG 8.19. Technical Rationale The technical rationale for application of these acceptance criteria to the areas of review addressed by this SRP section is discussed in
