System for processing radioactive wastes

Abstract

The invention relates to a system for processing radioactive wastes, which is integrated in a movable shelter including a volume-reduction device and a tail-gas processor connected to a pipeline of the volume-reduction device; and both the volume-reduction device and the tail-gas processor are placed in a vacuum environment. The invention provides a movable system for processing radioactive wastes, which reduces storage space, causes little pollution to the environment and is low in storage cost.

Description

technical field [0001] The invention relates to a treatment system for nuclear industry and nuclear power plant waste, in particular to a treatment system containing radioactive waste. Background technique [0002] As an efficient and clean energy, nuclear power has been increasingly valued and utilized by people. As of 2010, there were 13 nuclear power units in operation in mainland my country, and 24 units under construction will also be put into commercial operation successively. While nuclear power brings huge economic benefits to people, the technological wastes and technical wastes produced during the working process have a certain specific activity of radioactivity, and must be treated with certain technical measures before storage. , the radioactive pollution caused by natural or man-made damage such as earthquakes and terrorist attacks will bring disastrous consequences to people. At present, when these radioactive wastes are processed, cement solidification or inc...

Problems solved by technology

For the cement solidification method, radioactive waste is directly compressed and sealed with cement, which faces various challenges due to its large capacity expansion ratio, high storage cost, and large storage space.

For the incineration and filtration method, after incineration and filtration of radioactive waste, although the storage space can be alleviated to a large extent, and the storage cost will be reduced accordingly, but the pollution of the environment due to the dioxin produced by the incineration cannot be underestimated. At the same time, the current incineration method has a very large structure. In addition to the high investment intensity, its fixed structure has brought the disadvantages that the radioactive waste contained in each power station must be transferred to the volume reduction treatment center for treatment, which virtually increases the number of radioactive wastes. Due to the limitation of the heating method, the nuclides in the radioactive waste form aerosols and drift with the hot air flow during incineration, which not only increases the difficulty of tail gas treatment, but also increases the investment and pressure of treatment, which may further lead to secondary pollution. one or more pollution
