This report describes the result of Conceptual Design of the Alcohol Waste Treatment Equipment. The experimental fast Reactor, JOYO, saves the radioactive alcohol waste at storage tank. As this alcohol waste is not able to treat with existing equipment, it is stored about 5m. And the amount of this is increasing every year. So it is necessary to treat the alcohol waste by chemical resolution for example. On account of this, the investigative test about filtration and dialyzer, and conceptual design about catalyst oxidation process, which is composed from head end process to resolution, are done. The results of investigation show as follows. [(1)Investigative Test about filtration and dialyzer] (a)The electric conduction is suitable for the judgement of alkyl sodium hydrolysis. Alkyl sodium hydrolysis is completed below 39% alcohol concentration. (b)The microfiltration is likely to separate the solid in alcohol waste. (c)From laboratory test, the electrodialyzer is effective for sodium separation in alcohol waste. And sodium remove rate, 9699%, is confirmed. [(2)Conceptual Design] The candidate process is as follows. (a)The head end process is electrodialyzer, and chemical resolution process is catalyst oxidation. (b)The head end process is not installed, and chemical resolution process is catalyst oxidation. (c)The head end process is electrodialyzer, and alcohol extracted by pervaporation. In this Conceptual Design, as far these process, the components, treatment ability, properties of waste, chemical mass balance, safety for fire and explosion, and the plot plan are investigated. As a result, remodeling the existing facility into catalyst oxidation process is effective to treat the alcohol waste, and treatment ability is about 1.25/h.
