, 10 CFR 20.1905, or Standard Technical Specifications and to determine whether they will control access properly in limited and restricted access areas (high radiation and very high radiation areas). The staff will review SAR Chapters 5, 9 and 11 as necessary to evaluate dose rates in and around the spent fuel pool areas, the location of airborne radioactivity monitoring instruments within ventilation systems, and radwaste systems as they relate to radiation protection design. The reviewer will evaluate all relevant aspects of the initial design plans, particularly to identify new arrangements, improved designs, unusual shield thicknesses, a new or modified shield thickness calculational procedure, unusual assumptions in the calculation, and placement of radiation monitors. The staff responsible for the review of SRP Chapter 11 will evaluate the adequacy of the process and effluent radiation monitoring (e.g., sensitivity, range, system placement) design. 2. RG 1.97 and BTP 7-10 as referenced above, provide detailed guidance and criteria for post accident radiation monitoring instrumentation. The staff will coordinate the review of the radiation monitoring systems with the instrumentation and control and emergency preparedness review staff to ensure that adequate radiation detection instrumentation is provided for plant monitoring under accident conditions. 3. The health physics staff will evaluate the adequacy of the applicant’s shielding design on the basis of acceptable radiation shielding practices and calculation methods. Based on its review of the plant layout drawings and radiation zoning, the health physics staff may verify, by independent calculations, the adequacy of the shielding design for selected areas of the plant. The review should emphasize areas in the plant that have a potential to become a significant high radiation area (greater than 1 Gy (100 rads) per hour) or a very high radiation area during operations and AOOs. These areas include, but
