Neutron noise detection: in-core & ex-core Important information regarding the mechanical condition of reactors can be collected by measuring neutron flow fluctuations. Measurements conducted inside the core (in-core) with fission chambers. Measurements conducted outside the core (ex-core) with ionization chambers.   Modern noise analysis equipment. Immediate on-site analysis with a Labview programme. Laborelec experts developed this portable tool in-house for the acquisition and analysis of neutron noise.         Contact: Thierry DEBORSU P: +32 (0)2 382 0330
