excore
Excore refers to components, instrumentation, or measurements located outside the reactor core, a term widely used in nuclear reactor engineering. It contrasts with in-core instrumentation, which is embedded within the fuel or core region. Excore systems provide a means to monitor reactor conditions from outside the core and are integral to power monitoring, safety, and diagnostic functions.
Excore detectors include neutron detectors such as ionization chambers and fission chambers mounted on the reactor
Operational use and calibration: ex-core readings are usually calibrated against in-core data or standardized benchmarks to
