Description

Transmutation rates for the two long-lived fission products technetium 99 and iodine 129 have been calculated for the CANDU Actinide Burner that operates with weapons grade plutonium in an inert matrix as fuel. These transmutation rates are compared with those obtained for the current natural uranium CANDU and for LWRs and FBRs. The higher thermal flux and the softer neutron spectrum of the CANDU Actinide Burner, which is a result of its lower fissile requirements can provide net transmutation half lives as short as 14 y for technetium 99 and 2 y for iodine 129. It is assumed that the iodine 129 can be irradiated as a solution in heavy water. The shorter half life for iodine 129 is due to the large volume of moderator and reflector available that leads to negligible self shielding of the iodine 129 cross section.
