As shown in FIG. 1, the aqueous ammonia solution reservoir 3 is one in which ammonia included in the aqueous ammonia solution stored in the reservoir reacts with uranyl nitrate included in the drops of the feedstock liquid falling from the nozzles 4 and the reaction produces ammonium diuranate. The aqueous ammonia solution reservoir 3 has a hemisphere-like curved bottom and a cylindrical sidewall. The aqueous ammonia solution is stored in a volume up to a predetermined level in the reservoir 3. The cylindrical body is extended upward beyond the level of the aqueous ammonia solution stored in the reservoir 3. The aqueous ammonia solution reservoir 3 is provided with ammonia gas-supplying pipes 9 that are arranged on the sidewall above the level of the aqueous ammonia solution 10. The ammonia gas supplied from the ammonia gas-supplying pipes 9 makes the space over the level of the aqueous ammonia solution 10 inside the aqueous ammonia solution reservoir 3 an atmosphere of ammonia gas.
