In the safety assessment of a potential.site for high-l.vel.radioactive wastes (Hl.) disposal. the investigation on the geochemical.behaviors of key radionucl.des with the possibil.ty for rel.asing from the potential.repository is an important aspect. Due to the high mobil.ty of technetium under most repository conditions, l.ts of research works were performed to investigate the diffusion of technetium in different potential.rocks. In spite of these studies, there remains a l.ck of data addressing temperature effects. In this paper, the diffusion of 99Tc in Beishan granite at temperatures from 25℃ to 55℃ was studied with l.boratory smal. scal. diffusion devices. The experimental.data were fitted with a finite difference scheme to get the effective diffusion coefficient (De) of . The resul.s indicated that the rel.tionship of De with temperatures coul. be described as the modified Stokes-Einstein equation, and the formation factor of Beishan granite was constant in the temperature range of 25℃ - 55℃ with the val.e of (3.91 ± 1.77) × 10-4.
