Keywords:uranium, radioactive waste, nuclear fuel fabrication facilities, sludge, incinerated ash, leaching tests, nitric acid

Leaching tests were carried out to separate uranium from actual wastes of sludge and incinerated ash stored in nuclear fuel fabrication facilities. The conditions for effective leaching and removal of uranium from the wastes were confirmed using nitric acid as the leaching solution.
