Thermal conductivities of (U, Pu, Am)O2 solid solutions

Thermal conductivity of (U,Pu,Np)O2 solid solutions

“…These results were compared with the thermal conductivities of MOX fuel containing Am-oxide previously obtained by Morimoto et al [7].…”

“…Details of this apparatus have been described elsewhere [7]. The data obtained experimentally were analyzed by the curve-fitting method [9], and thermal diffusivities were figured out.…”

“…The porosity influences of specimens on thermal conductivities were corrected by the modified Maxwell-Eucken relation: F(p) = (1 À p)/(1 À bp), where b = 0.5 was from the result of Morimoto et al [7]. The thermal conductivities k 0 of a 100% theoretical density specimen were obtained from the conductivity k of a real specimen at porosity p.…”

Thermal conductivity measurement of (Pu1−xAmx)O2 (x=0.028, 0.072)

“…), and k p is the thermal conductivity with porosity p. In this study, b was a constant value (=0.5) that was obtained by Morimoto et al [14] for a specimen with density greater than 84% T.D.…”

Innovative oxide fuels doped with minor actinides for use in fast reactors

“…Measurement results of melting temperature by Kato et al [10] and thermal conductivity by Morimoto et al [11] showed that Am effects on these properties were not so large, namely both melting temperature and thermal conductivity of Am-MOX with Am content of up to 3.3 % were almost the same level as those of MOX. This was also confirmed analytically by Kurosaki et al [12] in a molecular dynamics simulation.…”
