  • Mono on the move with sintec

    Mono’s Widethroat W range pump forms an essential part of Sintec’s mobile system by pumping the thicker groutmixes more quickly and efficiently. Once the mobile system is in-situ and drilling of an exploratory hole is almost complete, a mixer combines the bentonite/cement grouts to form bentonite slurry. This is then transferred by the W Range pump to the holdingtank ready for injection into the ...

  • An inflatable tunnel seal stops flooding of world`s largest undeveloped uranium mine

    The Cigar Lake Mine, located in the Athabasca Basin of Northern Saskatchewan, Canada, is sitting on the world's largest undeveloped high-grade uranium deposit in the world.

  • Dredging at weldon spring super fund project Morrison Knudsen - St. Charles, Missouri, USA

    Remote controlled Dredging proved to be the best method of removing radioactive sludge from settling ponds of a former uranium processing plant near St. Charles, Missouri. Dredging keeps the material wet and out of contact with the atmosphere throughout the removal and treatment process, eliminating the danger of contaminates becoming airborne. The Weldon Spring Site Remedial Action Project ...

  • Remote control dredge prevents contamination at Fernald, Ohio nuclear remediation site

    When the operations manager at the Fernald, Ohio Super Fund Site Remedial Action Project needed a dredge to remediate sludge from one of four on-site waste (raffinate) pits, they required more than the usual dredging standards. The dredging operation was complicated with the possibility of unknown radon emissions, chemical contamination, and radiation that could be unleashed as material was ...

  • New LWT system improves safety for workers dredging radioactive materials

    Problem: Cleanup crews wanted to dredge radioactive sludge from hazardous waste pits without releasing contaminants to the environment. Solution: A remote-control system encloses the radioactive material during dredging and keeps workers at a safe distance. The Weldon Springs, Mo. Superfund site and remedial action project has four pits containing low-level radioactive raffinate debris and ...

  • Common Treatment Technologies for Radionuclides in Soil, Sediment, and Sludge

    Unlike organic contaminants (and similar to metals), radionuclides cannot be destroyed or degraded; therefore, remediation technologies applicable to radionuclides involve separation, concentration/volume reduction, and/or immobilization. The most commonly used treatment technology for radionuclides in soil, sediment, and sludge is solidification/stabilization (S/S). This treatment technology is ...

  • Storing Heat Underground

    Underground thermal energy storage (UTES) is a system that uses inter-seasonal heat storage, storing excess heat from the summer for use in winter heating, and the cooling potential from winter for cooling in summer. A cost-effective, low-energy and low-risk proven renewable technology, UTES reduces carbon emissions by up to 60% and is becoming an increasingly popular choice for residential, ...
