Title:
NEUTRON FLUX MAPPING DEVICE FOR REACTOR
Document Type and Number:
Japanese Patent JPS5552994
Kind Code:
A
Abstract:
A nuclear reactor flux mapping system having a plurality of neutron detectors operable to be driven into and out of a reactor core along any one of a number of pre-established paths. The detectors, corresponding drives (22) and drive controllers (28) are arranged into at least two physically separate and functionally independent channels. Each channel is respectively arranged to scan complementary paths through the core during normal system operation. At least two, redundant, functionally independent and physically separate "command end of processing" channels (31 and 33) are provided. Each of the command and processing channels (30) are independently operable to automatically, programmably sequence the detector scans and process the detector output data on all of the detector channels while being electrically buffered from each detector channel through two-ported memories (36) in a manner to prevent faults on any of the channels from disabling any of the other system channels. Each detector channel is operable to scan the entire core in the event the other detector channel should prove inoperable.
