Stabilization of in-tank residual wastes and external-tank soil contamination for the tank focus area, Hanford tank initiative: Applications to the AX Tank Farm

“…Program conditions has been demonstrated (Wakeley and Ernzen, 1992). We also recommend a similar lift pouring strategy with sufficient intervening time to allow for the heat liberated in setting to dissipate.…”

Stabilization of in-tank residual wastes and external-tank soil contamination for the tank focus area, Hanford Tank Initiative: Applications to the AX tank farm

“…Costs are on the order of $125 per ton of material. Wakeley and Emzen (1992) developed a Portland cement-based grout with the appropriate rheological and thermal properties for "mass emplacement." Components of the grout are those typical of most Portland cements so the cost of the materials will be similar to those of normal concrete.…”

Quality assurance plan for placement of cold-cap grout, demonstration vault, Hanford Grout Vault Program. Final report

“…In 1991, the WES developed a nonradioactive grout to be used to fill the space between the PSW grout and the cover blocks of the demonstration vault, to be placed during vault closure operations. Grout requirements and development are reported elsewhere (Wakeley, et al 1992;Wakeley and Ernzen 1992a,b).…”
