The Automated Device For Leak-testing Of Nuclear Fuel On Their Manufacturing
Automation of manufacture and quality control of nuclear fuel is a necessary condition of achievement of ambitious plans for atomic power development in the countries which join in process of an intensification of nuclear energy development. The modern automated industrial line is complex of modern machinery, automatized and computerized systems. As for leak testing of industrial products, it is very difficult to automatize them. As a rule, it is necessary to adapt technology of the control and automatized control device to each other. The aim of this paper is description of the automatized leak-testing devices for fuel elements for light water reactors which are used at factories of concern JSC TVEL (Russia). The leak-testing devices are intended for work in the modern automated lines of nuclear fuel manufacturing. Its main feature is the open vacuum system representing the tube with inlet and outlet vacuum sluice. The length of all chamber is smaller then length of a separate fuel element. Part of the tube between two sluices is high-vacuum test chamber with own exhaust unit. Fuel elements one by one pass through the high-vacuum chamber connected with helium leak-tester. Thus all length of each fuel element tests for leakage consistently. Due to small volume of the vacuum chamber, the device has short the response time and high sensitivity. All parts of the device operate under computer control under special program. If any leak had been detected, a defected fuel element will be rejected from product flow; place of defect will be marked.
