THE INSPECTION APPARATUS FOR NUCLEAR FUEL ROD ASSEMBLY

摘要

PURPOSE: A nuclear fuel assembly inspecting device is provided to remarkably improve an inspection speed by arranging a plurality of transmission and reception ultrasonic probe modules to inspect the nuclear fuel assembly through one reciprocation. CONSTITUTION: A computer(410) collects control and ultrasonic signals. A driving unit controller(420) is connected to the computer for collecting the control and ultrasonic signals. A transmission ultrasonic probe and a reception ultrasonic probe are arranged on an inspection table(400) in the longitudinal direction of a fuel rod(105). The inspection table is installed in a fuel storage tank. An ultrasonic transceiver(430) displays an ultrasonic signal received from the inspection table on a screen.
