AI Technical Summary
Temperature changes in the environment surrounding nuclear radiation detectors cause inaccuracies in the output signal, leading to incorrect measurements of reactor power level and distribution, particularly in high-temperature reactors like High Temperature Gas Reactors and Liquid Metal Reactors.
Incorporating a temperature compensation assembly with a metallic signal lead, insulative material, and metallic sheath, similar to a mineral insulated cable, to measure and compensate for temperature-induced changes in leakage resistance, allowing for accurate determination of reactor power levels and distributions.
The solution maintains accurate radiation measurement by correcting temperature-related output signal changes, ensuring reliable operation of nuclear reactors even at high temperatures.
