A programmatic risk assessment of the Hanford Double Shell Tank Waste Remediation Program was performed (Miller, 1991a). The assessment addressed the technical, regulatory and programmatic uncertainties associated with the characterization, retrieval, pretreatment and vitrification of the various wastes stored in double shell tanks on the Hanford Reservation. Early in the assessment, regulatory uncertainties associated with permitting the B Plant and AR Vault facilities for use as pretreatment facilities were identified as major contributors to the overall risk to the program. A study was subsequently initiated, the Tank Waste Disposal Program Redefinition Study, to (1) identify a set of tank waste disposal strategy options; (2) develop a basis for selecting one or more preferred candidates; and, (3) perform a rigorous selection process resulting in identification of one or more recommended candidates as an alternative to the baseline strategy. Science Applications International Corporation (SAIC) was retained by Westinghouse Hanford Corporation (WHC) to modify and apply to the pretreatment options the computer based risk analysis model originally developed as part of the Hanford Waste Vitrification Systems Risk Assessment (HWVSRA) (Miller, 1991b, Appendix B). The quantified cost uncertainties, schedule uncertainties and success probabilities for each of the pretreatment options would then be utilized as one set of parameters in a multi-attribute utility decision process. The following report provides the results of the analyses. This report is intended to be issued as a stand-alone supplement for the WHC document Tank Waste Disposal Program Redefinition (Grygiel, 1991), which presents the pretreatment options, describes the technical bases for each option, develops the comparative bases for the options and selects one or more pretreatment options as preferred alternatives.
