Nuclear waste packaging device

Abstract

The invention discloses a nuclear waste packaging device. A radiation-shielded packaging layer of the packaging device is of a multilayered structure and successively comprises an inner packaging container layer, a lead alloy layer, a radiation-proof concrete layer, an outer packaging container layer and a waterproof cover layer from inside to outside; the thickness of the inner packaging container layer is 2-6cm; the thickness of the lead alloy layer is 3-8cm; the thickness of the radiation-proof concrete layer is 5-10cm; the thickness of the outer packaging container layer is 3-7cm; the thickness of the waterproof cover layer is 1-2cm. The device is simple in structure, high in containing capacity and not liable to corrode; the leakage of radionuclides can be completely avoided.

Description

technical field [0001] The present invention relates to the technical field of nuclear waste treatment equipment, in particular to a nuclear waste treatment device, and more specifically to a radiation shielding packaging layer structure for a nuclear waste treatment device. Background technique [0002] The development of the nuclear industry, especially the rapid development of nuclear power plants, has produced a large amount of nuclear waste. Generally speaking, nuclear waste includes two types of low- and medium-level radioactive nuclear waste and high-level radioactive nuclear waste. Radioactive waste liquid and waste, such as waste resin, activated carbon, waste filter core, evaporated boron-containing waste liquid, etc., account for 99% of all nuclear waste, and the latter refers to the replacement from the nuclear power plant reactor core Burned nuclear fuel is commonly known as high-level radioactive waste because it is highly radioactive. Among them, low- and med...

Problems solved by technology

[0004] 1. There are often microcracks in this type of barrel, resulting in the leakage of nuclear waste;

[0005] 2. This type of barrel is often damaged due to bumping during the transfer process, resulting in nuclear waste leakage;

[0006] 3. This barrel has a short service life and is prone to accidents, endangering the personal safety of staff

[0008] In addition, steel drums are used as long-term disposal containers for nuclear waste. Due to the poor corrosion resistance of steel drums, subsequent temporary storage, transportation, and final disposal all increase radiation risks.

Furthermore, the use of cement solidification method to treat low- and medium-level radioactive nuclear waste has the possibility of decomposition and chemical reaction again, resulting in swelling and cracking, causing radioactive liquid to leak out and pollute the environment.
