10 CFR Part 20.101, 20.103, and 20.104, as well as the radiation protection aspects of General 12.3-6 Rev. 2 - July 1981 Design Criteria 19 and 61, and 10 CFR 50.34. This includes evidence that major exposure accumulating functions (maintenance, refueling, radioactive material handling, processing, etc., in-service inspection, calibration, decommissioning, and recovery from accidents) have been considered in plant design and that potential radiation exposure from these activities will be kept ALARA in accordance with 10 CFR Part 20.1(c) and Regulatory Guides 8.8 and 8.10 by radiation protection features incorporated in the design. Such features may include (1) ease of accessibility to work and inspection and sampljng areas, (2) the ability to reduce source intensity, (3) design measures to reduce the production, distribution, and retention of activated corrosion products, (4) the ability to reduce time required in radiation fields, and (5) provision for portable shielding and remote handling tools. Access control will be judged for acceptability in accordance with the requirements of 10 CFR 20.203 or access control alternatives in Standard Technical Specifications (tUREGs-0103, 0123, 0212, and 0452). Access controls to the spent fuel transfer tube or canal should be more stringent than 10 CFR 20.203. All accessible portions of the spent fuel transfer tube or canal which are capable of having radiation levels greater than 100 rads per hour shall be shielded during fuel transfer. Use of removable shielding for this purpose is acceptable. This shielding shall be such that the result- ant contact radiation levels shall be no greater than 100 rads per hour. All accessible portions of the spent fuel transfer tube shall be clearly marked with a sign stating that potentially lethal radiation fields are possible during fuel transfer. If removable shielding is used for the fuel transfer tubes, it must also be explicitly marked as above. If other than permanent shielding is
