Background

When the nuclear power station is overhauled, the refueling water pool is used for loading and refueling nuclear fuel for the reactor, and the whole refueling water pool is filled with water with radioactivity. In the operation process of a reactor, equipment, pipelines and valves forming part of the loop are washed at high temperature (more than 300 ℃) and high pressure (more than 15 MPa) at high flow rate and under the influence of the chemical environment of the loop, surface materials are inevitably partially corroded and stripped to form metal corrosive slag, when the metal corrosive slag flows through a reactor core along with water of the loop, the metal corrosive slag is irradiated by high-flux neutrons, part nuclides of the metal corrosive slag are activated to become radionuclides such as Co-58, Co-60, Cr-51, Mn-54 and the like, and the activated metal corrosive slag is called as activated corrosion products. The activated corrosion products, which may be highly radioactive depending on their degree of activation and amount of accumulation, are transferred to various parts of the circuit as it is operated, and enter the refueling water basin during refueling. During refueling, metal sludge or debris adhering to the surfaces of the fuel elements may be transferred to the refueling water pool as the fuel elements move. These activated corrosion products or fuel element surface fragments may be highly radioactive and pose a threat to radiation safety for refueling pool personnel. In order to remove the activated corrosion products or the surface fragments of the fuel elements, a water suction device is used for filtering the water in the refueling water pool, the activated corrosion products or the surface fragments of the fuel elements are absorbed, the used filter element of the underwater dust collector accumulates more radioactive substances, and the best method is to put the filter element into a shielding container underwater and then transfer the filter element to a storage area for ensuring safety, but the prior art lacks the corresponding shielding container.
