Creators

Description

Object: To exactly position a fuel exchanger by mounting an ultrasonic transmitter and an receiver therefor at the lower end of a fuel gripping means. Structure: Ultrasonic waves are transmitted against a support lattice for a fuel assembly, the reflected waves from an upper surface of the lattice frame are received by a detector to produce a signal, a truck is moved on rails according to the signal to lower a positioning support on a mesh, a fuel exchanger is then lowered through the same path and a fuel assembly is gripped and pulled out of the reactor core.
