Description
Technical Field
The utility model belongs to the technical field of radioactive solid waste handles, concretely relates to radioactive solid waste shielding waterwall.
Background
For radioactive solid waste, the treatment mode at home and abroad usually adopts the steps of barreling in a process plant, then sending the barreled solid waste to a solid waste conversion station for sorting, smelting and deeply burying the sorted metal waste, burning the sorted non-metal combustible waste and deeply burying the burned non-metal non-combustible waste, and compressing and deeply burying the sorted non-metal non-combustible waste.
Nuclear fuel reprocessing generates large quantities of solid waste with high levels of radioactivity during commissioning and production operations. Because of large volume and different shapes, the solid waste can not be directly loaded into a round solid waste barrel and then transferred to a production plant. And the production plant is not provided with a solid waste disintegration hot chamber, large pieces and non-circular radioactive solid wastes cannot be disintegrated one by one, and even if the large pieces and the non-circular radioactive solid wastes can be disintegrated, the solid waste conversion station cannot receive the large pieces and the non-circular radioactive solid wastes due to more quantity and types of the large pieces and the non-circular radioactive solid wastes.
Therefore, only radioactive solid wastes that cannot be barreled can be temporarily stored in the production plant. Because the radioactivity level is high, the radioactive solid waste can not be packed in a sealed bag as low-radioactivity solid waste and then accumulated in a certain idle area in a factory building to be provided with an isolation and warning board. To reduce the radioactivity level in the buffer and the exposure dose to the operators in the plant, radioactive solid waste shielding buffers must be provided. Typically, the use of lead sheath or brick is an effective method of shielding radioactive sources. However, the radioactive solid waste is large in volume and large in quantity, and the required storage space is usually dozens of cubes or hundreds of cubes. Therefore, the lead bricks or lead sheets are adopted for shielding, so that the using amount is too large, the price is high, the local bearing load of the floor slab is also greatly increased, and the requirement on the bearing of the floor slab is high. In addition, the support frame is required to be built, the lead shielding wall is built, the building and the dismantling are inconvenient, and the dismantling in the future also requires personnel to closely clean and decontaminate the lead block or the lead skin, so that the irradiation dose of the operating personnel is increased, and the like.
