Title: Treatment of high level radioactive waste
Inventor: HORIE MIZUAKI
IPC: G21F9/14
Filed: 1990-03-15
Abstract: PURPOSE:To treat high level radioactive wastes without generating a huge amount of secondary wastes and to materialize highly volume reduction of them by heating up the high level radioactive wastes to get a calcined body and then by heating up again at very high temperature and sintering powder of the calcined body of the high level radioactive wastes which are obtained after vaporizing and removing a Cs by heating in a non-oxidative atmosphere. CONSTITUTION:A Cs is vaporized and removed by heating up high level radioactive wastes and by vaporizing a water content and a nitric acid to get a calcined body, and then by heating up again in a nonoxidative atmosphere. By this treatment, restrictions related to synthesis of a solidified body regarding to Cs confinement are eliminated. Then, by heating up the calcined body of high level radioactive wastes to make them a sintered body, high volume reduction is materialized. Since the calcined body has an ability of self sintering, the sintered body can be obtained by putting the calcined body in a vessel and heating it up. Moreover, under higher pressure, a much more dense and stably shaped solidified body can be obtained. As it is not for use as molded goods, 300 atoms as so-called high pressure is more than enough for producing such a densely solidified body.

Abstract: PURPOSE:To eliminate the need for a driver dedicated to a low-speed operating element, by temporarily stopping or invalidating a terminal scan while a common controller is in control operation. CONSTITUTION:Common controller 3 continues to take a terminal scan until a connection or disconnection request is generated by an originating terminal. Once input information is genrated by one of originating terminals A1-An, the input information is stored in memory circuit M- corresponding to the originating terminal A-. When the scanning counter of common controller 3 counts up and ''1'' is set to the set terminal S of gate circuit GT- corresponding to the correspnding originating terminal A-, this gate circuit is opened to apply the input information to buffer memory circuit BUF of the common controller. Simultanesouly, it is applied to OR circuit DCK, the output of which stops the scanning counter from counting up. While stopping the terminal scan, the common controller starts controlling a switch selectiong relay unit and circuit exchange switch in the processing sequence based upon a time stage determined by the output of a stage counter.
