abstract

In the process of decommissioning of the nuclear facilities, abandoned and contaminated equipments or devices often need to be dismantled and cut into proper pieces in order to facilitate subsequent treatment and disposal. Since the nuclear facilities were places where radioactive operations were frequently executed, gloveboxes should be such typical abandoned and contaminated devices. Usually, gloveboxes were cut into proper pieces by kinds of tools which was chosen depending on the thickness of stainless steel from different parts of gloveboxes. This traditional cutting was laborious and high concentration of harmful aerosols and gases would be created during the cutting operation. In order to develop more advanced cutting and disintegration ways, a cutting and disintegration device was developed using abandoned and contaminated gloveboxes as operation objects in this work. During the design of this device, the operation convenience, operation exactitude and the protection for operators were fully considered. Also, the hot verification test was carried out. Based on the verification test results, the cutting and disintegration device was reliable and could meet the design requirements, which precisely executed various movements required in the hot verification test. Due to the application of remote operation and advanced cold cutting as the main cutting way in the development of this cutting and disintegration device, radioactive aerosols and harmful gases created during operation of this device were obviously declined compared to past cutting devices, which was of great importance to the health of operators. This work can provide technical support for the development of other similar devices applied in nuclear facility decommissioning.
