Decontamination and Decommissioning (D&D) and Environmental Restoration / Waste Management (ER/WM)

Consultation and analytical testing provided by MCLinc’s scientists and engineers have supported D&D and ER/WM projects in the areas of:

  • Specialty environmental analysis – chemical characterization of waste materials, industrial hygiene support, identification of unknowns and analysis of samples not amenable to standard or routine environmental techniques
  • Bench scale testing of chemical processes – decontamination and waste stabilization
  • Demonstration and deployment support – providing technical evaluation, problem solving, and process optimization
  • Technical support – troubleshooting, compatibility studies, and interpretation of analytical data to ensure optimal performance

MCLinc gaseous diffusion plant cleanup experience includes:

  • Identification of unknowns
  • Sampling/purging fluorinating gases in process headers
  • Design of systems to recover UF6 from off gases
  • Evaluation of systems for removal and/or stabilization of uranium deposits
  • Development of solubility coefficients for transport modeling
  • Neutralization and blending of solids recovered from process piping
  • Metallurgical investigations
  • Accident investigation
  • Explosivity testing
  • UF6 exposure testing
  • Solidification/stabilization/encapsulation testing
  • In-Cylinder UF6 neutralization; downblending studies
  • Speciation and sequential extraction studies in support of remediation of uranium in soils
