MINIATURIZED LOW-INERTIA DEVICE WITH BUILT-IN ENERGY SOURCE FOR TIER-BY-TIER DETECTION OF NEUTRON FLUX IN NUCLEAR REACTOR

摘要

nuclear power engineering. SUBSTANCE: device has set of identical core elements 22 distributed within tubular external can 18 throughout longitudinal axis of this can. Each cell element 22 is sensitive to local neutron flux. Changes in flux are continuously monitored throughput entire height of reactor core when device is placed in one of channels for recording detectors. All connecting wires 24 connected to core elements 22 are of same length as compensating wire also placed in can 18. EFFECT: enhanced reliability of neutron flux detection. 22 cl, 8 dwg
