Content:
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 radioactive material are a potential sources of radiation exposure to individual workers in the event of leakage of the systems or components, during normal operation, anticipated operational occurrences, or in the event of an accident. Meeting the requirement of GDC 61 provides a level of assurance that releases of radioactive materials during normal operation and during anticipated operational occurrences will not result in radiation doses that exceed the limits specified in 10 CFR Part 20. In addition, meeting the requirement will help assure that systems continue to perform safety functions under postulated accident conditions.79 4. Compliance with the requirements of 10 CFR Part 70 §70.24 requires installation of a system that will energize clearly audible alarm signals if an accidental criticality occurs. In addition, emergency procedures are required for each area in which special nuclear material is handled, used, or stored. Accidental criticality is a possibility wherever special nuclear material is handled, used, or stored. Operating procedures relative to maintaining subcritical geometries of special nuclear materials, training of personnel in the handling of the materials, the equipment and facilities used to manipulate the materials, and fundamental controls for accounting for the special nuclear material are all required. These requirements, collectively, provide assurance that an unanticipated nuclear criticality accident will not occur. Meeting these requirements provides assurance that personnel who work in the vicinity of special nuclear material will not be subject to excessive radiation exposure should an accidental criticality occur.80 III.
