摘要：
The thermal conductivities of actinide mononitride solid solutions, (U,Np)N and (Np,Pu)N, were determined from thermal diffusivities measured using the laser flash method from 740 to 1630 K. It was found that the thermal conductivities of the solid solutions have a similar temperature dependence to that of the respective mononitride and decreased from the UN-side to the PuN-side in order, especially in the UN-rich region for (U,Np)N and the NpN-rich region for (Np,Pu)N over the temperature range investigated.
