OSTI ID:4834300

In order to measure the temperature inside each of a series of fuel elements, stacked one upon the other in vertical reactor channels, each element comprises at both ends contact means able to effect electrical contact with the corresponding contact means of the adjacent end of the succeeding fuel element. The fuel elements each have at their upper ends a number of concentric contact rings provided at the same level and at their lower ends eccentrically positioned contact means able to make contact with the contact rings of the next lower fuel element. One of the upper contact rings of each fuel element is connected with the hot junction of a thermocouple situated in this element, each of the other rings being connected with corresponding contact means at the lower end of the same fuel element by cables passing through the fuel element body, so that each of the hot junctions of the thermocouples of all the lower positioned fuel elements is connected with one of the contact rings of the uppermost fuel element. Contact means are provided to connect these latter contact rings, and thus all the thermocouple junctions, with the measuring instruments. (NPO)
