Field test of radionuclide migration. Cooperative research between JAERI and CIRP

Technical Report:

Abstract

To establish a safety evaluation methodology for shallow land disposal of low level radioactive waste, cooperative research had been undertaken between Japan Atomic Energy Research Institute(JAERI) and China Institute for Radiation Protection(CIRP). Field tests on migration of {sup 3}H, {sup 60}Co, {sup 134}Cs and {sup 85}Sr were conducted during under both artificial and natural rain conditions, and laboratory experiments and site characteristics investigations were conducted to obtain information on migration parameters for evaluation of the radionuclide migration. Migration behavior of the radionuclides under the artificial rain condition, in which behavior of infiltrating water was kept at a constant, agreed well with that estimated by migration parameters obtained in the laboratory experiments. Under artificial rain condition, the peak position of {sup 85}Sr distribution moved to 10 cm downward from the start tracing position, while the almost part of {sup 60}Co and {sup 134}Cs did not move. Under the natural rain condition, all the peak positions of three radionuclides did not move. These results suggested that the migration of {sup 60}Co, {sup 134}Cs and {sup 85}Sr was significantly retarded by the loess medium. The {sup 85}Sr migration under artificial rain condition was well described by the equilibrium sorption model using distribution coefficient.  More>>

The {sup 85}Sr migration under artificial rain condition was well described by the equilibrium sorption model using distribution coefficient. As to the {sup 60}Co and {sup 134}Cs migration, the kinetic sorption model indicated better explanation. Infiltration of soilwater under natural rain condition was analyzed by using the amounts of precipitation and evaporation obtained from the investigation of site characteristics. Migration of these radionuclides under natural rain condition could be evaluated by the combination of migration parameter and sorption-migration model obtained from the analysis of the test under artificial rain condition, the laboratory experiments, and the investigation of site characteristics.
