Solubility and diffusivity of hydrogen isotopes in liquid Pb17Li

AbstractThe results of measurements of solubility S and diffusivity D of hydrogen isotopes in Pb17Li in the temperature range from 508 K to 700 K are presented: SH = √P02.44 × 10−8exp(−1350/RT), SD = √P02.36 × 10−8exp(−1350/RT), ST = √P02.32 × 10−8exp(−1350/RT), D = 4.03 × 10−8exp(−19500/RT), where S is given in atomic fractions, D in m2/s, P0 in Pa, T in K and R = 8.31 J/(mol K).These results are compared with those of other authors.
