Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] The low-enriched uranium target is a cylinder with a smooth metal appearance. The length of the cylinder is generally 5cm to 35cm, and the outer diameter is Φ2cm to Φ10cm. The invention designs a target grabber capable of grabbing cylinders and polygons with more than three sides, and can also be used for grabbing work that cannot be operated by manipulators in a hot chamber.

[0026] The grasping device mainly considers the applicability of grasping targets of different shapes, the stability and accuracy of operation. The grasping device of the present invention is hoisted in the heat chamber through the control steel cable from the top of the heat chamber into the heat chamber, moves up and down, left and right by controlling the steel rope, and grasps the target and other objects through the cooperation of the manipulator.

Abstract

The invention discloses an irradiation target grasping device used in a hot chamber, which comprises a claw piece, a grasping control component, a claw tension adjustment component, a remote control cable and a controller; the claw piece is respectively connected with the The grasping control component is connected with the gripper tension adjustment component; the grasping control component and the gripper tension adjustment component are both connected to the controller through the remote control cable. The beneficial effects of the present invention are as follows: the target grasping device designed by the present invention can be operated remotely by the operator outside the heat chamber through the control cable, and can grasp objects at any position in the heat chamber, especially for ordinary target lead cans. Grab the irradiated target in the center, avoiding the special design of the target transport lead can for the hot cell manipulator, the opening of the gripper can be adjusted freely to suit different space sizes of the lead can.

Description

technical field [0001] The invention relates to the field of nuclear industry, in particular to an irradiation target grasping device used in a hot chamber. Background technique [0002] 99m Tc drug is the most widely used radiodiagnostic drug in modern nuclear medicine. The nuclide is generally made of artificial radionuclide 99 Mo decays to a half-life of 66h. Production 99 There are many ways of Mo, but the main way is that the reactor irradiates U-235 through fission reaction 99 Mo and other products, of which 99 Mo accounts for 6.1% (mass percentage) of fission products. Uranium target ( 235 U) After entering the pile, a fission reaction will occur under the action of thermal neutrons, and the reaction cross section is 586b. The fission reaction equation is: [0003] 235 U+n→ 236 U+ 99 Mo+ 134 Sn+3n [0004] Currently, 99 The main source of Mo is the use of reactors to irradiate uranium-235 ( 235 U) After fission, it is extracted and purified from the fis...
