Environmental and Chemical Process Technology Research Programs

The Environmental and Chemical Process Technology Research Programs focuses on research and development enabling nuclear materials processing and site cleanup and waste disposition across the DOE complex.  This broad range of programs utilizes SRNL expertise in nuclear chemical engineering, actinide chemistry and separations science, materials science and engineering and experience in the development, deployment and continuing refinement of critical processes and technologies for the DOE cleanup mission.  SRNL scientists and engineers utilize hands on experience to perform research and development from bench scale to pilot scale in support of key program areas, including:

Nuclear materials processing

  • Material characterization
  • Flow-sheet development and refinement
  • Process demonstration, and qualification

Waste treatment and disposition

  • Chemical and physical characterization of waste materials to support facility operations and enable process development
  • Waste form development, characterization and qualification

Tank cleaning and closure

  • Development of chemical flow sheet for tank cleaning
  • Grout formulation for tank closure
  • Residual waste characterization
