Evaluation of Methods for Immobilizing Solids Loaded with Krypton-85.

摘要

Seven methods of immobilizing solid granules loaded with krypton-85are evaluated for krypton leakage,radiation resistance,physical strength,and heat transfer. The methods use (1) glass matrices, (2) metal matrices, (3) polymer matrices, (4) pressed (isostatic) matrices, (5) cement blocks, (6) bitumen blocks,and (7) porous metal containers. The sintered-metal matrices,polymer matrices,pressed (isostatic) matrices and porous metal containers are the most promising methods. Further development work is needed to determine the volume increase and krypton leakage rate of the immobilized solid. (ERA citation 03:006056)
