Abstract

The present invention relates to crud sample collecting apparatus for nuclear rod comprising crud sampling chamber (100) and crud sample colleting device (200), which can easily collect sample to analyze its component, and the nuclear rod will not be destroyed and the operation efficiency of the reaction furnace will not be reduced when sampling, wherein, the crud sampling chamber (100) comprises a chamber body (140); upwards guide flange (110); a blade section (130); a downwards guide flange (120), wherein the upwards guide flange is arranged on upper end of the chamber (140) for the nuclear rod entering the crud sampling chamber (100); the blade section is positioned at middle of the chamber (140) for collecting crud; the downwards guide flange (120) is positioned at lower end of the chamber (140) for removing nuclear rod from the nuclear rod storing groove rack.

Description

technical field [0001] The invention relates to a dirt sample collection device for collecting corrosion deposits accumulated on the surface of nuclear fuel rods. Background technique [0002] Corrosion products are often accumulated on the surface of various pipes or nuclear fuel rods in atomic reactors of nuclear power plants. These corrosion products are called dirt (CRUD: Chalk River Unidentified Deposit). [0003] Dirt is generally produced by corrosion deposits produced by the components that make up the primary system in the furnace or boron dissolved in cooling water. This kind of dirt is highly radioactive and accumulates on the surface of nuclear fuel rods to reduce the output and make the upper and lower output deviations (AOA: axial offset anomaly or CIPS (crud induced power shift) exceeds the limit value, causing accidents such as early interruption of power plant operation, and requires a lot of cost in terms of operating efficiency. [0004] In view of the a...
