REACTOR CONTROL SYSTEM MEASURING CHANNEL Russian patent published in 1997 - IPC

FIELD: checking parameters of fuel assemblies of experimental and power-generating water-moderated and boiling reactors. SUBSTANCE: measuring channel has casing, holding set of cable-type thermoelectric converters with hot junctions placed in coolant flow inside reactor and cold junctions arranged outside reactor for checking their temperature, as well as direct-charge set of detectors mounted at desired height or reactor core and provided with cable connected to communication lines of data processing and measuring system. Emitter length of each direct-charge detector is at least 0.05 m and not over 0.15 m, emitter diameter of each detector is minimum 0.001 m and maximum 0.005 m. Emitter of each direct-charge detector is connected to one conductor of cable provided with other, background, conductor. Number of direct-charge detectors is to be minimum six and distance between emitter centers of adjacent direct-charge detectors through their height is at least three times that of emitter length. EFFECT: improved reliability. 3 cl, 1 dwg
