EQUIPMENT FOR THE MEASUREMENT OF THE FUEL ELEMENT TEMPERATURES INSIDE NUCLEAR REACTORS

Patent ·
OSTI ID:4055448
A reactor fuel element is described in which one or more thermocouples are arranged within the canning material The thermocouple junctions are connected with spring loaded contacts, which are pushed in the radial direction against contact pieces attached to the inner wall of the fuel element channel, at places corresponding to the working positions of the fuel element. These contact pieces are in further connection with the measuring instrument. The contact pieces are suitably fitted in a piece of ceramic material and form a part of its surface. These ceramic pieces have inclined surfaces close to the contact pieces so that the spring loaded contacts reach to the channel wall only at the working position of the fuel element. (NPO)
