Abstract

The high cost of storing large volumes of metallic radioactive and mixed waste make the application of decontamination techniques for volume reduction an attractive alternative.

The availability of decontamination-for-release technology options provides a path forward to economically decontaminate and release metallic waste for disposal as clean scrap. Also, contaminated tools and equipment can be economically decontaminated for unrestricted refurbishment or reuse rather than disposed of after only a one-time usage.

 

Kinectrics has investigated and applied a number of decontamination approaches to reduce the activity of various metallic wastes, as well as tools and equipment, to below free release limits. These include both mechanical and chemical methods. This paper presents an overview of the various decontamination-for-release approaches employed to date by Kinectrics for the following applications:

 

  • Decontamination of metallic radioactive waste and its unconditional release as scrap metal.
  • Decontamination of metallic radioactive tools and equipment for refurbishment and reuse.
