Description
For the safe disposal of radioactive waste, it is necessary to review the soundness of radioactive waste and engineering barrier. To evaluate cement concrete for the low level radioactive waste disposal facility, we researched the structural integrity. Experiment was performed using ANS 16.1 leach test procedure. The diffusion coefficients for Ca and Si isotopes were determined. Semi-infinite model was used for analysis of the controlling mechanism in the release of isotopes. Diffusion coefficients of Ca were 3.7762E-13 cm2/s for the sample immersed in simulated seawater and 1.3693E-12 cm2/s for the sample immersed in deionized water. Diffusion coefficients of Si were 2.4510E-16 cm2/s for the sample immersed in simulated seawater and 4.4568E-14 cm2/s for the sample immersed in deionized water
