    摘要: A washer and a method of controlling operation of the washer is provided. The washer includes a main body; a washing chamber which is disposed in the main body and accommodates a stuff to be washed, including a water outlet formed on the bottom surface thereof and a water feed inlet on one end of which a shower nozzle is formed; an ultrasonic oscillator generating vibration in the washing chamber; and a control unit which can control a washing process, wherein the washing chamber includes an overflow hole through which washing water can overflow from the washing chamber. The washer performs an initial washing operation and a main washing operation in combination. In the initial washing operation, stuffs to be washed such as fruits and vegetables are contained in the washing chamber and then water is supplied on the stuffs to be washed through the shower nozzle in a showering manner to then be discharged so that foreign matter stick to the stuffs can be primarily removed. In the main washing operation, water is re-supplied into the washing chamber to fill the washing chamber up, to then perform the main washing operation called an ultrasonic washing operation through the ultrasonic oscillator. During performing the main washing operation, water is additionally fed in every period of time in a manner that a certain amount of floating matter can be flown out through the overflow hole. As a result, light foreign matter floating in the water among the foreign matter detached from the stuffs to be washed is flown out together with the water, to thereby prevent floating foreign matter from sticking again to the stuffs during washing and improve a washing effect. The washer can automatically and cleanly wash stuffs such as fruits and vegetables to be washed which requires a long washing time, to thereby provide an effect of shortening the whole washing time.

    摘要: A method of manufacturing new UO2-based fuel pellets by recycling irradiated UO2-based fuel pellets. Irradiated UO2-based fuel pellets are oxidized so as to make U3O8-based powder, and then the U3O8 -based powder is mixed with an additive which contains at least one oxide of an element selected from the group consisting of niobium, titanium, vanadium, aluminum, magnesium, chromium, silicon and lithium. Green pellets are formed from the mixed powder, and then sintered, preferably at 1500° C. or higher, in a reducing gas atmosphere to produce UO2-based fuel pellets with high densities.
