Immobilization of carbon-14 from reactor graphite waste by use of self-sustaining reaction in the C–Al–TiO2 system
Source abstract
Abstract
Abstract As a result of long-term neutron irradiation, the long-lived 14 C is produced in the reactor graphite. The exothermic self-sustaining reaction 3C(graphite) + 4Al + 3TiO 2 = 3TiC + 2Al 2 O 3 was proposed for processing of such waste. In doing so, the carbon, including the 14 C, is chemically bound in the stable TiC. The reaction products in the C–Al–TiO 2 system were investigated both by thermodynamic simulation and experimentally in the course of this work.
