PROBLEM TO BE SOLVED: To provide a method and an apparatus for wet processing of uranium waste that generates a small amount of secondary waste and has small medicine expenses. SOLUTION: In the wet processing method, various types of uranium are separated and recovered from the uranium waste, where uranium, transuranic or a radioactive nuclide element, or various types of compound uranium are adhered. The wet processing method comprises a solution process S1 for generating solution by dissolving the uranium waste with a mask agent; a precipitation process S2 for precipitating various kinds of uranium from the solution; a trace of uranium elimination process S3 for eliminating a trace of various kinds of uranium remaining in the solution after eliminating deposits by using a uranium adsorption resin; a mask agent recovery process S8 for returning the mask agent used in the precipitation process to the dissolution process after recovering from the solution; and a residual fluorine elimination process S5 for eliminating fluorine or a fluorine compound remaining in the solution by using the fluorine adsorption resin.
