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 Technical Position ETSB 11-3, and satisfies applicable transportation and disposal site requirements. For purposes of this appendix, dewatered resins or filter sludges satisfying the two latter criteria shall also be defined under this waste classification. (b) Dewatered resins and sludges should be stored in containers that satisfy receiving burial site criteria, in addition to applicable transportation regulations. Any storage plans should address container protection as well as any reprocessing requirements for eventual shipment and burial. (c) Casks, tanks, and liners containing solidified radioactive waste should be designed with good engineering judgement to preclude or reduce the occurrence of uncontrolled releases of radioactive materials due to handling, transporting, or storage. Accident mitigation and control for design basis events (e.g., fire, flood- ing, tornadoes, etc.) must be evaluated and protected against unless otherwise justified. (d) The following design objectives and criteria are applicable for solidified waste storage containers and facilities: (1) All solidified radwaste should be located in restricted areas where effective material control accountability can be maintained. While structures are not required to meet seismic criteria, protection should be afforded to insure the radio- activity is contained safely by use of good engineering judgment, such as the use of curbs and drains to contain spills of dewatered resins or sludges. (2) If the waste product is potentially corrosive, proven provisions should be made to protect the container (i.e., special liners or coatings) and, or neutralize the waste. If deemed appropriate and necessary, highly noncorrosive materials (e.g., stainless steel) should be used. Potential corrosion between the
