Resistance temperature detectors (RTDs) are used for safety-related measurements in nuclear power plants and must therefore be accurate and respond to temperature changes in a timely fashion. Experience has shown that RTD calibration shift and response-time degradation can occur with aging. Therefore, periodic testing is performed to ensure that acceptable performance limits are not exceeded. A new method called the loop current step response (LCSR) test is used for periodic response-time testing of nuclear plant RTDs. This method permits testing the RTD as installed in an operating plant (in situ testing). The LCSR test is based on heating the RTD sensing element with a small electric current applied remotely through the sensor lead wires.
