ce the volume of waste shipped off site. Special provisions are needed to assure that contaminated airborne radioactivity is not released to the process area during compaction. BTP 11-3-2 Revision 3 - March 2007 Liquid wet wastes, such as evaporator and reverse osmosis concentrates, are stabilized (i.e., combined with a suitable binder) before shipping to render the waste immobile and thereby mitigate the consequences of potential ruptures to shipping containers. Other wet wastes, such as spent resins (beads or powdered) and filter sludge, are either stabilized or dewatered before shipping. Spent cartridge filter elements are packaged with suitable absorbers in shielded containers or stabilized before shipping. Although a number of available processes are capable of solidifying wet wastes under controlled conditions, free liquids can potentially remain in containers following stabilization, given widely varying chemical species encountered during power plant operations. For the purpose of this position paper, free liquid is defined as liquid that is still visible after stabilization or dewatering is complete, is drainable from the low point of a punctured container, or is drainable from a localized pool trapped within a waste matrix. Based on the NRC staff’s judgment, vendors and operators need to implement certain measures to accomplish the following: • Establish process parameters within which systems must be operated to obtain complete stabilization, encapsulation, solidification, as applicable • Assure proper waste form properties are achieved • Assure systems are operated within established process parameters • Have provisions to detect free liquid in containers and waste matrix before shipment off site Similar restrictions apply to dewatered products to provide greater assurance that these products meet the receiving burial site’s free liquid restrictions at the time of receipt. Following packaging, wastes are normally stored for decay of shorter
