ctivity monitoring system (building exhaust vents) where there is a potential for airborne radioactivity to be generated or to accumulate. IV. WET RADIOACTIVE WASTE STORAGE 1. Wet radioactive waste is defined as any liquid, liquid/solid slurry, or process concentrate. For storage considerations, wet waste is further defined as any waste that contains free liquid in amounts exceeding the requirements for burial as established by the burial ground licensing authority. 2. The design of the facility’s supporting structure and tanks should prevent uncontrolled and unmonitored releases of radioactive materials resulting from spillage or accident conditions. 3. The following design objectives and criteria apply to wet radioactive waste storage facilities: A. Structures that house liquid radwaste storage tanks should be designed to seismic criteria as defined in SRP Section 11.2 and Regulatory Guide 1.143 for wastes produced during normal operation and anticipated operational occurrences. Foundations and walls shall also be designed and fabricated to contain the liquid inventory that might be released during a container/tank failure. B. All tanks or containers should be designed to withstand the corrosive nature of the wet waste being stored. The design shall also consider the duration of storage under which the corrosive conditions exist. C. All storage structures should have curbs or elevated thresholds with floor drains and sumps to safely collect wet waste in the event of the failure of all tanks or containers. There should be provisions to remove spilled wet waste to the radwaste treatment systems. D. All tanks and containers shall have provisions to monitor liquid levels and to sound an alarm in the event of potential overflow conditions. 11.4-29 Revision 3 - March 2007 E. All potential release pathways of radionuclides (e.g., evolved gases, breach of container) shall be controlled, if feasible, and monitored in accordance with Appendix A to 10 CFR Part 50, GDC 60
