Preventing nuclear fuel material adhesion on glove box components using nanoparticle coating

Minimizing the retention of nuclear fuel materials in glove box components and curtailing the external exposure dose are desirable. Therefore, plutonium and uranium mixed oxide (MOX) powder adhesion-prevention technology involving nanoparticle coating of the acrylic panels of the glove box is develo...
