... system to which it will be applied, and the basis for not applying it to other parts of the SLAW system, as well as the basis for selecting the risk analysis techniques applied 1 According to DOE, low-activity waste means the waste that remains after as much of the radionuclides as technically and economically practicable have been removed from the tank waste, and that when immobilized in waste forms, may be disposed as low-level waste in a near surface facility. Supplemental treatment refers to processing of the low-activity waste that is excess to that portion to be treated as part of the Waste Treatment and Immobilization Plant (WTP)

... REGULATORY COMPLIANCE ASSESSMENT Significant disagreements about fundamental aspects of the regulatory environment could render any SLAW treatment options highly uncertain. One important uncertainty is departure from the widely assumed use of vitrification for producing glass waste forms unless the alternatives are shown to be "as good as glass," a standard that is widely repeated but not formally adopted or defined by state or federal governments.

... WASTE CONDITIONING AND SUPPLEMENTAL TREATMENT APPROACHES The FFRDC's draft working documents and presentations discuss the three primary supplemental treatment technologies: vitrification, grouting, and fluidized bed steam reforming. The FFRDC has not identified any other primary SLAW treatment technology, and the committee is not yet aware of any other primary technologies that are sufficiently developed or likely of success to warrant detailed analysis.

... General Comments The committee suggests that the FFRDC's forthcoming analytic report include:  An accessible organizational structure of the analytic approach that presents clear choices and their consequences to decision-makers, with the recognition that the FFRDC will not select a preferred supplemental treatment option.  A complete and consistent set of supplemental treatment alternatives specifying clearly whether just the major three supplemental treatment approaches are being assessed or whether there are any variations on these three to consider, including the processing, transportation, and disposal options in each alternative.
