“…Smaller increasesin Cl, F, Mg, K, Al, and Na solutionconcentrations were observed.The test that containedportions of all the waste types and cement (test #4) showed the largestchanges in inorganicchemistry. The leachate pH valuesSerne et al 1987).In all four tests the dissolvedorganic carbon contentwas significantly increased. The wood and paper leach test generatedmuch more dissolved organicmaterial than the other tests.…”

“…As was found for PSW grout (Serne et al 1987(Serne et al , 1989) and cladding removal waste {CRW} grout (to be reported), iodine, technetium, nitrite, nitrate, and sodium are leached more rapidly than other species. The effective diffusivities for the 106-AN grouts are larger than those measured on PSW and CRW grouts.…”

“….10 shows three possible configurations where monoliths or crushed and sieved Cast Stone waste form are packed in Hanford formation sediments within the columns. Such flow-through testing was quite successful in obtaining useful data on Hanford grout waste forms interacting with Hanford sediments that supported the past Grout PA (Serne et al 1987). The two leachants shown in Table 4.9 would be pumped through the columns at a constant flow rate.…”

iii SummaryThe Hanford Tank Waste Treatment and Immobilization Plant (WTP) is being constructed to treat the 56 million gallons of radioactive waste stored in 177 underground tanks at the Hanford Site. The WTP includes a pretreatment facility to separate the wastes into high-level waste (HLW) and low-activity waste (LAW) fractions for vitrification and disposal. The LAW will be converted to glass for final disposal at the Integrated Disposal Facility (IDF). The pretreatment facility will have the capacity to separate all of the tank wastes into the HLW and LAW fractions, and the HLW Vitrification Facility will have the capacity to vitrify all of the HLW. However, a second immobilization facility will be needed for the expected volume of LAW requiring immobilization. A number of alternatives, including Cast Stone-a cementitious waste form-are being considered to provide the additional LAW immobilization capacity.The supplemental immobilization waste form must be acceptable for disposal in the IDF. This supplemental immobilization waste form testing plan outlines the testing of the waste form and immobilization process to demonstrate that the Cast Stone waste form can comply with the disposal requirements.Specifications for the supplemental immobilization waste form have not been established. For this testing plan, Cast Stone specifications are derived from specifications for the immobilized LAW glass in the WTP contract, the waste acceptance criteria for the IDF, and the waste acceptance criteria in the IDF portion of the Hanford Facility Resource and Recovery Act (RCRA) Permit issued by the State of Washington. This testing plan outlines the testing needed to demonstrate that the waste form can comply with these waste form specifications and acceptance criteria. The testing program must also demonstrate that the immobilization process can be controlled to consistently provide an acceptable waste form product.
