Deep borehole disposal (DBD) is the concept of disposing high-level radioactive waste from nuclear reactors in extremely deep boreholes instead of in more traditional deep geological repositories that are excavated like mines. Deep borehole disposal seeks to place the waste as much as five kilometres (3 mi) beneath the surface of the Earth and ...
Slurry transport uses several methods: hydraulic conveying; conventional lean slurry conveying; and high concentration slurry disposal (HCSD). The latter, HCSD, is a relatively modern approach, which is used to transfer high throughputs of fine fly ash over long distances (>10 km or 6.2 mi) using high pressure diaphragm pumps with velocities of around 2 m/s.
When adequate pumping force is applied to "break the gel," flow resumes and the fluid returns to its free-flowing state. Many other chemicals (e.g. potassium formate) are added to a WBM system to achieve desired effects, including: viscosity control, shale stability, enhance drilling rate of penetration, and cooling and lubricating of equipment.
Bentonite layers from an ancient deposit of weathered volcanic ash tuff in Wyoming Gray shale and bentonites (Benton Shale; Colorado Springs, Colorado). Bentonite (/ ˈ b ɛ n t ə n aɪ t / BEN-tə-nyte) [1] [2] is an absorbent swelling clay consisting mostly of montmorillonite (a type of smectite) which can either be Na-montmorillonite or Ca-montmorillonite.

A sample of fuller's earth in its raw state from Pakistan. Fuller's earth is a term for various clays used as an absorbent, filter, or bleaching agent. Products labeled fuller's earth typically consist of palygorskite (also known as attapulgite) or bentonite. [1]
Waste Control Specialists LLC (WCS) is a treatment, storage, & disposal company dealing in radioactive, hazardous, and mixed wastes. Developed and controlled by Texas billionaire investor Harold Simmons until his death at the end of 2013, the company was founded in Dallas, Texas in 1989 as a landfill operator, and awarded a unique license for disposal of low level radioactive waste in 2009.
During the 1990s, the Texas Legislature moved to make natural-resource protection more efficient by consolidating programs. In 1991, it combined the Texas Water Commission and the Texas Air Control Board to create the first version of the TCEQ, known as the Texas Natural Resource Conservation Commission until fall 1993.
