IMPROVEMENTS IN OR RELATING TO DEVICES FOR THE DETECTION OF INDIVIDUAL FAULTY FUEL ELEMENTS AND THE PRECISE LOCATION OF THE POSITION OF THE FRACTURE ON THE SURFACE OF THE FAULTY ELEMENT
A device for detecting faulty fuel elements was invented which enables the individual faulty element to be found after the channel containing the fault has been detected. The basis of ihe device is the examination of individual elements in a neutron flux within the biological shield; the device comprises a rotatable basket located between the pressure vessel and the biological shield. The basket contains pockets for individual fuel elements and an inlet port for coolant to pass into the pockets. In operation, the basket containing fuel elements to be examined is rotated successively under a gas-collecting pipe whereby the gas emerging from individual pockets is collected and analyzed for radioactivity. The device can also be adapted for precisely locating the damage on the faulty fuel element. (D.L.C.)
