Structures for heat insulation of surfaces within a nuclear reactor

摘要

Each panel of a heat-insulating structure contains a stack of wire fabric elements and is maintained applied against the surface to be protected by means of a double fixing system comprising a tubular member which carries a clamping nut and a bearing plate, said member being rigidly fixed to the surface, and a threaded stud mounted coaxially within the tubular member. The stud carries a nut and a washer for preventing the panel from falling in the event of failure of the tubular member.
