il 1996 4. Compliance with GDC 60 requires that the nuclear power unit design shall include means to control suitably the release of radioactive materials in gaseous and liquid effluents and to handle radioactive solid wastes produced during normal reactor operation, including anticipated operational occurrences. GDC 60 specifies that the waste management systems provide for a holdup capacity sufficient to retain the radioactive waste particularly where unfavorable site environmental conditions may impose unusual operational limitations upon the release of the effluent. The holdup capacity also provides decay time for the shorter lived isotopes before they are processed further or released to the environment. The holdup times are used in the source term calculations provided for in NUREG-0016 and NUREG-0017. Meeting the requirement of GDC 60 provides assurance that releases of radioactive materials in liquid effluents to unrestricted areas during normal operation of the plant and during anticipated operational occurrences will not result in offsite radiation doses exceeding the limits specified in 10 CFR Part 50, Appendix I, and concentrations of radioactive material in liquid effluents in any unrestricted area exceeding the limits specified in 10 CFR Part 20, Appendix B, Table 2, Column 2.41 5. Compliance with GDC 61 requires that the liquid radioactive waste treatment system and other systems which may contain radioactivity shall be designed to ensure adequate safety under normal and postulated accident conditions. This criterion specifies that such facilities shall be designed with a capability to permit inspection and testing of components important to safety and with suitable shielding for radiation protection. Regulatory Guide 1.143 furnishes design guidance acceptable to the NRC staff related to seismic and quality group classification and quality assurance provisions for the subsystems, structures, and components of the liquid waste management system.
