A feeder-scanning technique that involves the measurement of $gamma$-ray fields on individual fuel-channel outlet-feeder pipes has been used successfully to locate failed fuel bundles in shutdown CANDU-PHW reactors at the Pickering G.S. High-resolution spectroscopic measurements show that the excess $gamma$-ray fields on the outlet feeders of channels containing fuel failures are due primarily to deposited fission products, all with half-lives longer than 56 hours.
