Experimental module for removal of radioactive slurry from Lrw storage tanks

This report gives information on elaboration and creation of an experimental module for removal radioactive slurry from LRW storage tanks. The main functional features of this experimental module are to suspend radioactive slurry packed in the bottom of a storage tank subjected to cleaning up, to suck the suspended radioactive slurry, to concentrate and separate radioactive slurry in a settling apparatus. The resulting flows from the module are concentrated and preconditioned radioactive slurry and LRW freed from solids. The concentrated and preconditioned radioactive slurry can be further directed for solidification by appropriate methods and LRW freed from solids can be cleaned by commonly used purification methods. The experimental module is supplied with a video-controlling system, which allows supervising the process of slurry removal. The experimental module is currently under testing with non-radioactive slurry therefore, there are no results of its application for real radioactive waste. (authors)
