    We report on the design and on the operation of a 14-GHz microwave system which heats droplets (2 to 4 mm diameter) of aqueous radioactive mixtures from 5 deg C to 100 deg C within 0.25 s during free fall. Additional, untreated free fall of 1 s turns the droplets to homogenous, spherical particles of uniform size which are used in the production of high- temperature-reactor nuclear fuel. A square cross-section Hsub(10p) cavity, positioned vertically, with optimized dimensions is fed with 90 W CW power and serves as an applicator. The problem of non-uniform heating of high-loss spherical droplets is treated in depth. (Author) CS
