any liquid or liquid/solid slurry. For storage considerations, wet waste is further defined as any waste which does not meet receiving burial site free liquid requirements for solidified or dewatered waste. (b) The facility, supporting structure and tanks should be designed to prevent uncontrolled releases of radioactive materials due to spillage or accident conditions. (c) The following design objectives and criteria are applicable for wet radioactive waste storage facilities. (1) Structures that house liquid radwaste storage tanks should be designed to seismic criteria as defined in Regulatory Guide 1.143, Section 5.0. Foundations and walls shall also be designed and fabricated to contain the liquid inventory which might be released during a container/tank failure. (2) All tanks or containers should be designed to withstand the corrosive nature of the wet waste storage. The duration of storage under which the corrosive condition's exist shall also be considered in the design. (3) All storage structures should have curbs or elevated thresholds with floor drains and sumps to safely collect wet waste assuming the failure of all tanks or containers. Provisions should be incorporated to route spilled wet waste to the radwaste treatment systems. (4) All tanks and containers shall have provisions to monitor liquid levels and to alarm potential overflow conditions. (5) All temporarily stored wet waste will require additional reprocessing prior to shipment offsite; therefore, provision should be established to integrate the required treatment with the waste processing and solidification systems. The interface and associated systems should'be designed and tested in accordance with the codes and standards described in Regulatory Guide 1.143. 11. 4-A-3 Rev. 0 - July 1981 3. Solidified Radioactive Waste Storaqe (a) Solidified radwaste shall be defined as wet waste (e.g., evaporator bottoms, resins, and sludge) which is solidified, meets the free liquid criteria of Branch
