Problems solved by technology

[0005] For example, the detection device is generally installed in a deep pit (Pit) at a depth of 5m from the nuclear waste storage tank of the power station. There is no detection device in use at present. In the absence of a clear cause of defective fuel and countermeasures, It is temporarily stored in the storage tank of the power station alone, so a safe permanent measure for judging whether it is defective fuel or not is required

Abstract

PURPOSE: By safeing and rapidly advancing the test process of the nuclear fuel the use after-edge flaw detection system improves the safety of the Atomic Electrical Power Plant equipment. CONSTITUTION: In the inside which canister is shut tightly with cover, the fuel is stored after use after use in the coke weighing hopper floor. The valve cone brush has the MC type pickup bolt for pulling up canister, and the pump and the valve sending the nuclide sample to the reservoir outside. The equipment panel is installed outside reservoir(100).

Description

technical field [0001] The invention relates to nuclear waste of heavy water furnaces, in particular to a system capable of soundness detection in time when an abnormality occurs in the nuclear waste. Background technique [0002] In general, nuclear fuel assemblies for heavy water furnaces include: uranium sintered bodies that generate heat through nuclear fission; fuel rods that house the sintered bodies in zirconium alloy cladding tubes; rod end joint plates that support both sides of the nuclear fuel assembly; sealed fuel rods Rod end caps at both ends; supports connected to fuel rods; spacers, etc. [0003] However, in the process of handling the nuclear fuel assembly inside the atomic furnace, defects may occur on the assembly due to interference between adjacent fuels or structures, etc., and such defects are also caused by the manufacturing process or improper design of the nuclear fuel. Therefore, in a nuclear power plant, a detection device capable of detecting fu...
