| Compacted bentonite has been chosen as the backfill material a high level nuclear waste repository (HLW). It has large sorption capability, low permeability and good sealing effect by swelling [1]. Diffusion processes of radionuclides in compacted bentonite are a good way to simulate radionuclide transport from the spent fuel to the environment around the repository in order to understand radionuclides interaction with bentonite. 79Se and 99Tc have received more attention because they are identified to be among the largest contributors to the performance associated with HLW. Previous researches have been carried out a lot of Se and Tc diffusion experiments [2, 3]. Research found that apparent diffusion coefficient Da values for HSe- are one order of magnitude smaller than those for SeO32- [4]. Capillary method study 99TcO4- diffusion in compacted bentonite from Gaomiaozi County found that Kd values from capillary teats are lower than those from batch tests and Kd is a strong function of dry density of the compacted bentonite [3]. |

| 壓實(shí)膨潤(rùn)土作為高水平放射性核廢料處置庫(kù)的回填材料(HLW)。其膨脹后[ 1 ]具有較大的吸附性能、低滲透性和良好的密封性。放射性核素在壓實(shí)膨潤(rùn)土中的從擴(kuò)散過(guò)程可以很好地模擬放射性核素從乏燃料遷移到周圍的環(huán)境的過(guò)程,以了解放射性核素遷移與膨潤(rùn)土的關(guān)系。79Se和99Tc因被確定為HLW性能的最大貢獻(xiàn)者之一受到了更多的關(guān)注。前人的研究已經(jīng)進(jìn)行了大量的硒和膽固醇的擴(kuò)散實(shí)驗(yàn)[ 2,3 ]。研究發(fā)現(xiàn),HSE的表觀擴(kuò)散系數(shù)Da值比SeO32-小了一個(gè)數(shù)量級(jí)[ 4 ]。毛細(xì)管法研究在高廟子縣膨潤(rùn)土中的99TcO4-的擴(kuò)散發(fā)現(xiàn)從毛細(xì)管試驗(yàn)所得的Kd值低于批量測(cè)試,Kd是壓實(shí)膨潤(rùn)土的干密度函數(shù)擴(kuò)散的一個(gè)重要指標(biāo)[ 3 ]。 |
