resins from other sources and tanks accumulating filter sludges should be capable of accommodating at least 30 days waste generation at normal generation rates. 2. Storage areas for solidified wastes should be capable of accommodating at least 30 days waste generation at normal generation rates. These storage areas should be located indoors. 11.4-9 Rev. 2 - July 1981 3. Storage areas for dry wastes and packaged contaminated equipment should be capable of accommodating at least one full offsite waste shipment. IV. PORTABLE SOLID WASTE SYSTEMS The following supplementary guidance should be incorporated into the design and use of portable (mobile) solidification and/or dewatering systems: 1. Tanks containing wet wastes are limited to inplant installation, they should not be part of the portable system. 2. The use of flexible piping should be limited to necessary interfaces with plant systems. Such piping is also subject to the hydrostatic test requirements delineated in Regulatory Guide 1.143. 3. Portable systems should be located, as a minimum, on concrete pads with curbs and drainage provisions for containing radioactive spills. Pro- visions should be available for interfacing the drains with the plant's liquid radwaste system. Portable systems should have integral ventilation systems with either self-contained filters, or interface with the plant's ventilation exhaust system. 4. Regulatory Guide 1.143 seismic criteria for structures housing solid waste systems are not applicable. V. ADDITIONAL DESIGN FEATURES The following additional design features should be incorporated into the design of the solid waste system. 1. Evaporator concentrate piping and tanks should have heat tracing if the concentrates are likely to solidify at ambient temperatures. 2. Components and piping which contain radioactive slurries should have flushing connections. 3. Solidification agents should be stored in low radiation areas, generally less than 2.5 mr/hr, with provisions for sampling.
