Review of Multibarrier Waste from Development

摘要

The application of coatings and matrices as part of a multibarrier concept for the immobilization of nuclear wastes has been demonstrated by several investigators. The multibarrier concept provides an enhanced waste form by improvements in mechanical strength, leach resistance, and thermal stability. Process complexity is increased in the multibarrier process due to additional processing steps, high-coating temperatures, molten metal transfer, and flammable coating gas mixtures.
