IMPROVEMENTS IN OR RELATING TO CONTAMINATION DETECTION ARRANGEMENTS

Patent ·
OSTI ID:4765259
A switching device is designed for detecting sheath fractures in heterogeneous reactors. In this device, the cooling ducts of the reactor are connected in sets and the sets in groups, with a primary detector for each group. Each set has a sampling circuit common to all the ducts of that set, and the sampling circuits in each group are arranged to be successively diverted to the primary detector in response to a single instruction transmitter. When an irregularity is discovered in a set, each duct in that set is successively examined by a supervisory detector. (D.L.C.)
