Leaching experiments with deionized water at 70 C have been carried out to ascertain the effect of oxidizing and anaerobic conditions and the presence of Boom clay on Np release from Synroc. The normalized solution leach rates of Np measured in these experiments are about a factor of 10 lower under reducing conditions than oxidizing conditions and the presence of Boom clay was found not to enhance the leaching of Np from Synroc. Neptunium was found to be predominantly in the mobile fraction and was not removed from the leaching solutions significantly by filtration or ultrafiltration.
