Abstract

To improve the CFCs characteristics of chemical erosion, tritium retention, and H2O/air resistivity, silicon doped CFCs were developed in the framework of European Technology programme. The tritium retention, H2O reaction kinetics, outgassing behaviour and depletion of silicon in doped CFCs were investigated as a function of silicon concentration and temperature. The results show that silicon in bulk of CFCs decreases the tritium bulk retention and the H2O reactivity. However, it has been observed that the concentration of silicon is slightly decreased at elevated temperature. This paper presents the experimental results and the consequence is discussed. © 1995, All rights reserved.
