Book Description
Isotope separation by means of infrared-laser multiple-photon dissociation offers an efficient way to recover tritium from contaminated light or heavy water found in fission and fusion reactors. For tritium recovery from heavy water, chemical exchange of tritium into deuterated chloroform is followed by selective laser dissociation of tritiated chloroform and removal of the tritiated photoproduct, TCl. The single-step separation factor is at least 2700 and is probably greater than 5000. Here we present a description of the tritium recovery process, along with recent accomplishments in photochemical studies and engineering analysis of a recovery system.

Tritium Recovery from Contaminated Water Via Infrared Laser Multiple-photon Dissociation

Book Description
The present aim of this program is photochemical removal of the 7 ppM concentration of DTO in D2O that is presently found in active heavy water fission reactors (e.g., Savannah River). Though only T/D recovery is under present scrutiny at LLNL, T/H separation can also be performed using infrared laser multiple-photon dissociation (MPD). Laser-based tritium recovery from both light and heavy water may prove to be of great importance in fusion reactors. The overall cycle of the process under investigation entails initial tritiation of a fully deuterated working molecule by catalyzed chemical exchange with the contaminated heavy water, followed by isotopically-selective, room temperature, gas phase, pulsed infrared laser MPD of only the monotritiated molecules, among the transparent, majority fully deuterated specie. In the MPD interaction, the resonant molecule selectively absorbs 30 or more infrared quanta and then dissociates. The tritium-enriched photoproducts are easily removed from the reactant mainstream by physical separation means. Then the cycle continues with retritiation of the photochemically-detritiated working molecule.
