<p>PURPOSE:To provide an apparatus for measuring nuclear reactor power in which the apparatus is simplified, its life is prolonged, a moving mechanism is eliminated and a required reactor inside environment is strengthened. CONSTITUTION:The apparatus for measuring nuclear reactor power comprises an ultrasonic wave guide rod 10 inserted into coolant in a reactor core 6 and provided with a hat insulation cavity from coolant at predetermined interval in the longitudinal direction, an ultrasonic wave transceiver 11 electrically connected to the rod 10 and provided out of a nuclear reactor 5, and a signal processor 12 for calculating the atomic energy power from the difference of propagating times of ultrasonic pulses of the rod 10 measured by the transceiver 11 into atomic energy power.</p> |
