Description

In uranium-plutonium mixed oxide (MOX) fuel fabrication, the mitigation of specifications on fuel design is considered from a viewpoint of improvement of economic efficiency. The density of UO2 pellets was controlled and the thermal conductivities of specimens were measured. The thermal conductivities decrease monotonically with increasing porosity in porosity range from 0.08 to 0.15. On the other hand, significant change of the thermal conductivities were not observed in porosity range from 0.15 to 0.20. (author)
