OSTI ID:4033007

A radioactivity monitor for monitoring the effluent from coolant tubes of a nuclear reacter is described. There is a first detecter adapted to detect radioactivity from all the tubes. Then there is a valve means adapted to cause the effluent from each coolant tube to flow through a sample pot individual to the coolant tube. When the radioactivity rises to a predetermined level in the first detector, a second detector scans and indicates the radioactivity of each sample pot therefore giving the effluent from each coolant tube. The second detectcr is shielded and rotates automatically when the predetermined level is reached. The sample pots are arranged in a circle around the second detector. A layout of the monitoring system is shown. (N.W.R.)
