EXPERIMENTAL ANALYSIS OF RADIOACTIVITY RELEASED BY LOW-LEVEL AND INTERMEDIATE-LEVEL RADIOACTIVE WASTE

Objective

THE PURPOSE OF THE RESEARCH PROJECT IS TO DETERMINE, UNDER SIMULATED REPOSITORY CONDITIONS, THE RELEASE TO AIR OF RADIONUCLIDES FROM CEMENTED ION EXCHANGE RESINS ORIGINATING FROM REACTOR COOLANT PURIFICATION SYSTEMS IN PRESSURIZED WATER REACTORS. THE RADIONUCLIDES CONCERNED ARE H3, C14, I129, FE55, NI63 AND ALPHA-EMITTERS.
AS RADIONUCLIDES H3, C14 AND I129 CAN FORM VOLATILE COMPOUNDS, THEY ARE OF SPECIAL CONCERN WITH REGARD TO ULTIMATE DISPOSAL. FE55 AND NI63, WHICH OCCUR IN ION EXCHANGE RESINS IN REACTOR COOLANT PURIFICATION SYSTEMS, ARE RELATIVELY LONG-LIVED AND DIFFICULT TO DETERMINE BY RADIOCHEMICAL ANALYSIS TECHNIQUES. THE PROJECT FURTHERMORE INCLUDES ANALYSIS OF THE RELEASE OF THE ABOVE RADIONUCLIDES VIA THE WATER PATHWAY.
The purpose of this research work is to determine, under simulated repository conditions, the release of airborne radionuclides from cemented ion exchange resins originating from reactor coolant purification systems of a pressurised water reactor. The radionuclides considered are hydrogen-3, carbon-14, iodine-129, iron-55, nickel-63 and alpha emitters. As radionuclides hydrogen-3, carbon-14 and iodine-129 can form volatile compounds, they are of special concern with regard to disposal. Iron-55 and nickel-63, which occur in ion exchange resins in reactor purification systems, are relatively long lived and difficult to determine by radiochemical analysis techniques. The work, furthermore, includes analysis of the release of the above radionuclides via the water pathway and the further development of analysis techniques.
