A shielded ion microprobe analyzer for elemental and isotopic analyses of irradiated fast reactor fuel and fuel component has been developed and installed in an alpha-gamma hot cell. Radiation shielding of the equipment ensures the radiation dose of <2 mR/h (5.16 x 10/sup -7/ C/kg) for 5 Ci (1.85 x 10/sup 11/ Bq) of a /sup 60/Co source. Hot samples can be automatically transferred from the cell to the sample chamber of the analyzer. Contamination inside the equipment through sputtering of the radioactive materials can be reduced with a special device. Distribution and migration of fission products, such as /sup 137/Cs, /sup 138/Ba, and /sup 90/Sr, and of fissile materials, such as /sup 235/U and /sup 239/Pu in irradiated mixed-oxide fuel, and isotopic ratios of the elements can be obtained very precisely and quickly.
