説明
<jats:title>Abstract</jats:title><jats:p>We made various nitride fuels containing simulated FP elements and evaluated the effect of these FP elements on the properties of the nitrides. For Uranium Neodymium nitride solid solution the lattice parameter increased with Nd content, thermal expansion coefficient did not change and thermal conductivity decreased with Nd content. The thermal expansion for Pd containing UN, where Pd precipitated as UPd3 in the grain boundaries of UN, was nearly the same as that of UN and the thermal conductivity for Pd containing in the UN matrix decreased with Pd content. For Mo containing UN Mo precipitated as Mo metal isotropically. Both the thermal expansion and thermal conductivity did not vary with Mo content This might result from the low Mo contents at these simulated burnups.</jats:p>
