The Alpha-Gamma Facility (AGF) at O-arai Engineering Center has been successfully operated for more than 16 yr. During this period, various irradiated fuel pins were received from JOYO, Japan Material Testing Reactor, and overseas reactors such as the Dounreay Fast Reactor, Rapsodie, Phenix, and the General Electric test reactor. The extension building of this facility has been in operation for approx. 7 yr. The main function of the extension building is physical and metallurgical examinations of highly irradiated mixed-oxide (MOX) fuel and cladding. Physical property measurement techniques have been developed such as melting point, thermal conductivity, and lattice parameter measurements. Equipment was modified or partially renewed to keep the activity level low. This paper describes melting point and thermal conductivity measurement techniques.
