WebFission chambers are ionization detectors used to detect neutrons. Fission chambers may be used as the intermediate range detectors to monitor neutron flux (reactor power) at the intermediate flux level. They also provide indications, alarms, and reactor trip signals. The design of this instrument is chosen to provide overlap between the source ... WebThese fission chambers are typically designed with a maximum operating temperature of 250°C (although some versions can monitor up to 600°C) and are equipped with an integrated mineral insulated cable and a HN …
