Apparatus and method for determining the power level of a nuclear reactor

摘要

The apparatus includes two or more electrical conductors, one or more signal devices, an analyzer and a time-domain reflectometer. The one or more signal devices may be adapted to apply one or more signals to the two or more electrical conductors and receive one or more signals from the two or more electrical conductors. The analyzer is adapted to determine power level in the nuclear reactor using at least one of the applied signals and at least one of the received signals. The method of determining power level in a nuclear reactor includes: measuring impedance values of two or more electrical conductors disposed in the nuclear reactor and using the measured impedance values to determine the power level.
