“…An ultrafine, cementitious grout with 90% of the particles smaller than 5 microns and an average particle size of 2 microns was developed for the shaft seal design (see Table 25). 92,93 The extremely small particle size would enable the grout to penetrate fractures present in the shaft(s) with apertures as small as 6 microns. This developed grout has the characteristics of 1) no water separation upon hydration, 2) low permeability paste, 3) fine particle size, 4) low hydrational heat, 5) no measurable agglomeration subsequent to mixing, 6) two hours of injectability subsequent to mixing, 7) short set time, 8) high compressive strength, and 9) competitive cost.…”

The Department of Energy (DOE) is tasked with managing the legacy defense wastes that resulted from nuclear materials production and nuclear arms development. Nuclear-waste management encompasses generation, processing (treatment and packaging), storage, transport, and disposal. To date, there are over 100 million gallons of liquid radioactive and chemical mixed wastes within the Department of Energy complex as well as solid waste, debris, and environmental restoration media that require disposal. DOE has been able to meet the challenges involved in dispositioning this waste using unique technical approaches and application-specific data required due to the nature of the constituents to be managed (e.g., long-lived radionuclides and highly mobile radionuclides in the near surface environments). Cementitious materials have played a prominent role historically in the successful disposition of these wastes, in the reduction of risk to the public, and in the closure of decommissioned tanks and facilities across the DOE complex. This document explores these applications and provides a review of how cementitious materials have been used across the DOE complex. The various approaches, formulations, processing techniques and disposal paths are discussed along with the requirements that drove the various cementitious systems and techniques used. Specifically, focus is provided regarding how/where cementitious materials are used for the following applications:
