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. DRAFT Rev. 3 - April 1996 11.4-16 3. Solidification agents should be stored in low radiation areas, generally less than 0.025 mSv/hr (2.5 mr/hr) , with provisions for sampling. 59 4. Tanks or equipment which use compressed gases for transport or drying of resins or filter sludges should be vented directly to the plant ventilation exhaust system which includes HEPA filters as a minimum. The vent design should prevent liquids and solids from entering the plant ventilation system. 11.4-17 DRAFT Rev. 3 - April 1996 APPENDIX 11.4-A DESIGN GUIDANCE FOR TEMPORARY ONSITE STORAGE OF LOW LEVEL RADIOACTIVE WASTE A. BACKGROUND Restrictions and reduced allocations at commercial burial sites have caused a need to actively consider increased onsite storage capacity in excess of that necessary to allow for decay of short-lived radionuclides and to allow for the possibility of shipping delays due to labor strikes. If such storage capability is planned, the applicant must assure that the design and operation of the proposed facility is adequate to maintain public health and safety, minimize risk to operating personnel, and present a minimal environmental impact. The objective of this appendix is to provide guidance to applicants considering onsite low level radioactive waste storage capabilities for several
