Cementation
In collaboration with its sister company WMT, NuVision Engineering, Inc. is one of the world's leading companies in the field of radioactive waste cementation, with capabilities and experience in all areas ranging from process/grout development and performance evaluation to commercial operation. We have an extensive customer base, which includes organizations such as UKAEA, BNFL, British Energy, USDOE and IAEA.
Our skills, developed in handling all types of waste streams, have been applied to the development, assessment and construction of waste receiving, sorting, segregation and sampling facilities (including waste inspection, characterization and categorization), waste volume reduction methods, waste containers and stores, retrieval systems and disposal facilities.
Our areas of expertise encompass:
- Waste sampling and characterization.
- Waste simulant development and production.
- Formulation development.
- Process development and optimization.
- Product performance evaluation.
- Support to plant design .
We have been involved in a wide range of projects where this expertise has been applied including:
- Support to the USDOE in the development and performance testing of formulations for the cementation of a range of high nitrate wastes, which may be generated during processing of the HLW calcine stored at the INEEL.
- Design, manufacture and construction of a facility for the treatment and immobilization of MTR waste liquors and their conversion to a solid form by encapsulation in cement for UKAEA at Dounreay;
- Development of cement formulations on a range of wastes including borates, active effluent treatment plant sludges, ion exchange resins, decontamination solutions and various sludges;
- Development of cementation processes and evaluation of product performance for a range of intermediate level wastes;
- Product development and full scale product evaluation for a number of waste streams including reactor sludge, test reactor reprocessing raffinate, supercompacted waste and decommissioning wastes
- Construction and operation of an in-drum cementation plant for encapsulation of low level wastes.
- Consulting support on methods for cementation of radioactive wastes generated during 99Mo production.
