Abstracts

EN

The behaviour of Polytetrafluoroethylene (PTFE), NAFION ionomer membranes and VITON fluoroelastomer in presence of high activity tritiated water (HTO) was analysed. Radiolytic stability of the fluoropolymers-HTO system was analysed by: (a) Simulation of radiolytic processes by quantum mechanical methods, (b) Simulation of radiolytic effects by exposure of fluoropolymers immersed in H₂O to ^{60}Co gamma radiation field, (c) Immersing of fluoropolymers samples in HTO with high activity, for different time periods. In both cases the samples were characterized by FT IR ATR, and study of emission of fluoride ions from polymer matrix.
