as a result of the applicant's radiation protection design review and from radiation exposure experience gained during the operation of other nuclear power plants. (Include examples of design features incorporated to reduce radiation to workers during maintenance operations, reduce radiation sources where operations must be performed, allow quick entry and easy access, provide remote operation capability or reduce the time required for work in radiation fields, and examples of other features that reduce radiation exposure of personnel.) These design features are consistent with those contained in Regulatory Guide 8.8 and are acceptable. Access control is in accordance with the requirements of 10 CFR 20.20320.1601, 20.1602, 20.1901, 20.1902, and 20.1903 and access control alternatives in Standard 88 Technical Specification (NUREGs-0103, 0123, 0212, and 04521430, 1431, 1432, 1433, and 1434) and is acceptable. 89 Areas within the restricted area will be divided into (number of zones) radiation zones. The dose rate criterion for each of these zones is derived from expected occupancy and access restrictions. These criteria are then used as the basis for the radiation shielding design. This allows for arrangements of radioactive equipment that are in accordance with the requirements of 10 CFR Part 20, and the guidelines of Regulatory Guide 8.8. During plant operation and refueling conditions, the Health physics staff will evaluate area access classifications, and monitor entry into areas to update posting and entry requirements in accordance with 10 CFR Part 20.20320.1601, 20.1602, 20.1901, 20.1902, and 20.1903 (and Standard Technical Specifications). 90 All plant radiation sources capable of producing radiation levels in excess of 1 Gy per hour (100 rads per hour) will be shielded and clearly marked, indicating that potentially 91 lethal radiation fields are possible. If other than permanent shielding is used, administrative controls will be initiated and local audible
