[3D03] Management of sorption distribution coefficients of radionuclides in low-level radioactive waste disposal facility

(III): Evaluation of the sorptive phase composition and its influence on Kd of cementitious materials

*Jun Yasuda1, Hisao Satoh1, Takashi Kozawa1, Yutaro Sawaki1, Tomoya Yoshida1, Kazuko Haga2, Yoshihisa Kaneda2, Yutaro Kobayashi2 (1. JNFL, 2. Taiheiyo Consultant)

Keywords:low-level radioactive waste disposal facility, sorption distribution coefficients, compressive strength, hydrate composition

The relationships among compressive strength, hydrate composition, and Kd were studied from the results of the quantitative analysis of the sorptive phases in cementitious materials used for constructing disposal facilities.
