Tank Waste Remediation System tank waste pretreatment and vitrification process development testing requirements assessment

Abstract

This study assesses the technologies being proposed for pretreatment and vitrification of Hanford Site tank wastes and identifies issues that must be resolved by testing with nonradioactive simulants and actual. tank wastes. The issues are characterized to identify the levels of testing (lab, hot lab, bench, etc.).

Testing and development strategy for the tank waste remediation system

“…The proposed strategy integrates the normal systems engineering top-down approach (Swanson et al 1994, Orme 1994, Slaathaag and Orme 1994 with the bottom-up work that has assessed the requirements for process development testing (Eager 1993, Howden et al 1994, PNL 1994, Orme and Slaathaag 1994, Reynolds 1994a, Roal 1994, Waters 1994). …”

“…Examples are given of existing facilities that provide testing capabilities to meet testing needs. The strategy builds on other studies and other ongoing work (Howden et al 1994, Howden et al 1995.…”

Testing and development strategy for the tank waste remediation system

“…The testing requirements assessment (Howden 1994) examined testing needs through workshops and preparation of data sheets. The results of this work are shown in the table in Appendix C. A development priority table was prepared based on requirements determined by a review of the flowsheet (Slaathaug and Orme 1994).…”

“…The larger scale tests are primarily to test and run in equipment and instrumentation, not to optimize process parameters such as dissolution efficiency. The scale of testing is based on the assessment of needs for this process (Howden 1994, Reynolds 1994b):…”
