expected to cause external corrosion and possible degradation of container integrity. (7) Total curie and storage capacity limits should be established based on the design of the storage area and the safety features provided. The design capacity (ft , Ci) should be based on historical waste generation rates for 3 the specific facility, considering both volume minimization/reduction programs and the need for surge capacity due to operations which may generate unusually large amounts of waste. (8) Inventory records of waste types, contents, dates of storage, shipment, etc., should be maintained. 2. Wet Radioactive Waste Storage (a) Wet radioactive waste will be defined as 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 conditions 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
