Horizontal Shearing Machine for Spent Fuel Assembly

Abstract

The invention discloses a horizontal cutting machine for spent fuel components. The horizontal cutting machine is arranged in a material feeding hot chamber and a cutting hot chamber, and mainly consists of a material barrel and a cutting device component, wherein the upper parts of the material feeding hot chamber and the cutting hot chamber are separated by a shielding interwall. The horizontal cutting machine is characterized in that the material barrel is arranged in the material feeding hot chamber; the outer part of the material barrel is sleeved with a material barrel bracket; a support is arranged below the material barrel bracket; the left and upper part of the support is provided with a material barrel translation locking device; a material barrel translation outer support wheel is arranged on a horizontal extension cantilever section; a material loading well mouth is arranged on the lower right of the support; the inner part of the left side of the material barrel is provided with a gripper; the left and upper side of the gripper is provided with a gripper driving device, and the left and lower side of the gripper is provided with a component driving device; the right side of the material barrel is provided with an outlet flange; a material barrel anti-vibration device is arranged on the shielding interwall; a sealing door and a shielding sealing door are arranged above a passage hole, which communicates with the two hot chambers, in the shielding interwall; a cutting device is arranged in the cutting hot chamber; and a fixed door plate and a component limiting plate module are arranged at the material inlet of the cutting device.

Description

technical field [0001] The invention relates to a horizontal shearing machine for spent fuel assemblies, which belongs to the technical field of spent fuel reprocessing equipment at the rear end of the nuclear fuel cycle. Background technique [0002] The current mainstream power reactor spent fuel reprocessing process is the PUREX process. The first step of this process is the cutting and leaching of spent fuel assembly fuel rods, that is, cutting the cooled spent fuel rods into short sections and sending them into the dissolver. Solvents are used to dissolve the fuel pellets within the insoluble cladding for the purpose of recovering usable fissile material. At present, there are detailed reports of successfully operating spent fuel commercial reprocessing plants abroad, mainly UP3 in France and THORP in the United Kingdom. The horizontal shearing system for the head-end treatment of such commercial reprocessing plants generally includes the following four basic processes:...

AI Technical Summary

Problems solved by technology

These horizontal shearing systems are not suitable for small and medium-sized spent fuel reprocessing plants or intermediate pilot plants due to their complex technology and huge plant supporting equipment, which require high construction and operating costs.
