Abstract

원자력발전소에서 발생하는 가연성 중·저준위 방사성 폐기물을 유도전류식 용융로내에서 유리화하기 위하여 직접 투입하는 방사성 폐기물 공급장치에 관한 것이다. 본 발명의 장치는 가연성 폐기물이 투입관내에서 고온에 노출되는 것을 방지하기 위하여 투입관 주변을 물로 냉각하며 폐기물의 종류에 따라 다른 냉각온도을 적용할 수 있도록 하였다. 또한, 산소공급용 튜브를 냉각수 자켓내를 통하여 공급장치 하부의 환형 챔버에 연결하여 폐기물 투입시 그 주변으로 산소를 환형으로 골고루 공급하도록 한다. 기존의 폐기물 공급장치는 열분해후 생성된 재를 공급하므로 연소효과 및 배기체 발생량을 고려할 필요가 없으나 본 발명은 유리용융로에 방사성폐기물을 공급하고, 그 주위에 냉각수를 공급하며, 그리고 용융로 내부로의 산소를 공급하는 등 3가지 기능을 방사성폐기물 공급장치내로 통합하여 유리용융로내에서의 기밀을 향상시키고 용융로 내부에서 산소분위기를 고르게 유지하여 폐기물의 연소효과를 향상시킬 수 있도록 한다. 또한 공급장치의 높낮이를 조절하여 용융유리위의 폐기물로부터 거리를 변화시킬 수 있도록 설계되었다.The present invention relates to a radioactive waste feeder that directly inputs flammable medium and low level radioactive waste generated in a nuclear power plant to vitrify in an induction-type melting furnace. In order to prevent the flammable waste from being exposed to high temperatures in the input pipe, the apparatus of the present invention allows the surrounding of the input pipe to be cooled with water and to apply different cooling temperatures according to the type of waste. In addition, the oxygen supply tube is connected to the annular chamber of the lower part of the supply apparatus through the cooling water jacket to uniformly supply oxygen to the surroundings when the waste is introduced. Existing waste feeder supplies ash produced after pyrolysis, so it is not necessary to consider combustion effect and exhaust gas generation amount. However, the present invention supplies radioactive waste to glass melting furnace, coolant around it, and into the melting furnace. Three functions, such as supplying oxygen, are integrated into the radioactive waste feeder to improve airtightness in the glass melting furnace and to maintain the oxygen atmosphere evenly inside the furnace to improve the combustion effect of the waste. It is also designed to change the distance from the waste on the molten glass by adjusting the height of the feeder.
