are ALARA, and provide requirements for storage security of licensed radioactive materials. Meeting the requirements of the referenced sections of 10 CFR Part 20 will provide a level of assurance that exposure to radioactivity will be controlled such that individual workers will not receive radiation doses exceeding the limits specified in 10 CFR Part 20.77 2. Compliance with GDC 19 with regard to personnel radiation exposures inside the control room during design basis accident conditions requires a control room that will provide for access and occupancy under accident conditions while limiting radiation exposures to 50 mSv (5 Rem) or less for the whole body, or its equivalent to any part of the body, for the duration of the accident. A radiation dose associated with access and occupancy of the power reactor control room under accident conditions is specified so that personnel who are required to monitor and control the course of the accident will be able to perform these functions without concern for their personal health and safety. The limits on radiation dose is maintained by design of control room and associated support equipment. Guidance on evaluation of control room habitability during accidents is provided in Regulatory Guide 1.78, Regulatory Position C.6, and in SRP Section 6.4, Control Room Habitability System. DRAFT Rev. 3 - April 1996 12.3-14 Meeting this criterion provides assurance that those personnel needed to monitor and control an accident will be able to perform those functions effectively, without exceeding established radiation dose limits.78 3. Compliance with GDC 61 requires that systems which may contain radioactivity be designed to assure adequate safety under normal and postulated accident conditions. This criterion specifies that such facilities shall be designed with appropriate containment, confinement, and filtering systems. The requirements of this GDC apply to SRP Section 12.3-4 because systems and components that contain
