Fixing contamination with polymer sprays on large volumes of radioactive waste with the aim of containment
The aim of the research work is the development of new techniques to fix contamination and the containment of radioactive waste by using polyurethane paints. The following main work steps have been carried out : -determination of the polyurethane paint most suited for this application, based on water diffusion tests and diffusion of radio-elements; -choice of the spraying technique with respect to conditions of an ionizing environment; -pilot application of the technique on a dismantling site. The polyurethane paint selected is a solventless bicomponent paint manufactured by Bayer. The spraying device chosen (Isotherm PMS 70) and fitted with a Gusmer-Getrasur spray gun is able to operate in an ionising environment under satisfactory conditions (tested on two pilot work sites). The process generates no contaminated aerosols, but ensures perfect fixation of the ionising particles.
