Content:
containment, thereby reducing the concentration of fission products released to the environment after an accident. GDC 41 also includes redundancy and reliability requirements for such systems. GDC 41 applies to this section because control of fission products released from the containment after an accident may require an ESF atmosphere cleanup system. Meeting this criterion provides assurance that offsite radiation doses resulting from an accident will be within regulatory limits.48 3. Compliance with GDC 42 requires that containment atmosphere cleanup systems be designed to accommodate periodic inspection of important components such as filter frames, ducts, and piping. GDC 42 applies to this section because the containment atmosphere cleanup system may be an ESF. DRAFT Rev. 3 - April 1996 6.5.1-6 Meeting this criterion provides assurance that the equipment necessary to mitigate the consequences of an accident will maintain its functional capability.49 4. Compliance with GDC 43 requires that containment atmosphere cleanup systems be designed to accommodate periodic pressure and functional testing. GDC 42 applies to this section because the containment atmosphere cleanup system may be an ESF. Meeting this criterion provides assurance that the equipment necessary to mitigate an accident will maintain its functional capability.50 5. Compliance with GDC 61 requires that fuel storage and handling, radioactive waste, and other systems that may contain radioactive material be designed to ensure adequate safety under normal and postulated accident conditions. These systems shall be designed with appropriate containment, confinement, and filtering systems. GDC 61 applies to this section because attainment of the objectives for postulated accident conditions may require an ESF atmosphere cleanup system. Meeting this criterion provides assurance that offsite doses of radiation resulting from accident conditions will not exceed regulatory limits.51 6. Compliance with GDC 64
