Pulse radiolysis studies of liquid heavy water at temperatures up to 250 degrees C

This report documents the rate constants and associated activation energies for the reactions of the primary radical species, eaq-, ·OD and ·D, which are formed during the radiolysis of heavy water within the temperature range 20 to 250 oC. These heavy-water data have been compared with the corresponding information for light water. These kinetic data form part of the database that is required to model the aqueous radiation chemistry that occurs within the core of the heavy water cooled and moderated CANDU reactor. (author)
