Abstract
PURPOSE: To increase the safety of a reactor, by means of loothening the stress accumulation of ridging parts due to the thermal expansion of pellets by setting up between a cladding tube and pellets as an interposition of containing cylinders of fuel pellets.
CONSTITUTION: Containing cylinders of pellets 11 made of a metal which react with corrosive gases, are composed of circular cylindrical parts 9 whose inner diameters are larger than the outer diameters of fuel pellets 2 and their lengths of axial directions are shorter than the lengths of the pellets 2, and bottom parts 10 of circular plate shapes which are connected to these circular cylindrical parts 9 and which are perpendicular to the axial direction, and the fuel pellets 2 are contained at the upper and the lower parts of these bottom parts 10. When the containing cylinders 11 of fuel pellets and the fuel pellets 2 are overlapped mutually in a cladding tube 5, the pellets 2 are deformed by the thermal expansion, but the filure of the cladding tube can be prevented by means of loothening the stress accumulation and of avoiding the exposure of a corrosive atomosphere by the presence of the containing cylinders 11.
