Summary of information for U.K. -- Information request on gamma flux monitor

Technical Report ·
DOI:https://doi.org/10.2172/10158532· OSTI ID:10158532
Summarized herein is the available information on the subject, ``Reactor Gamma Flux Monitors.`` Apparently, a misunderstanding exists between the U.K. representatives and the related information presented by Dr. Nilson at the Argonne meeting July 24 and 25th. Dr. Nilson`s reference at the US/UK meeting was to the use of gamma-compensated neutron detection chambers at Hanford. Such chambers have been designed and used in one old reactor for a short period as a prototype for a detector for the octant monitor system. No gamma compensated chambers are in any of the reactors at present. Under development is a neutron flux indicating system which will operate in the intermediate range (10{sup {minus}7} to 10{sup {minus}1} full power) and will use commercially available gamma compensated ion chambers. These will be used to provide signals for reactor period meters. At Hanford there has been no operating experience with gamma flux monitors as such or with extensive in core neutron flux monitors. Characteristics of systems under development are given for information as well as current information on the octant system.
