FIELD: electrical engineering. SUBSTANCE: invention is related to devices testing nuclear reactors where densities of neutron flux and flux of gamma quanta at different levels by height of active zone are converted to output electric signals under all operational conditions of reactor installation. Proposed equipment includes several ionization chambers with internal conduits and electric leads from each chamber placed in sequence. Ionization chambers are filled with mixture of inert gases under same excessive pressure and are connected by means of cables placed in flexible, sealed, metal hoses. Electric signals from ionization chambers are sent over communication cables to signal processing unit. EFFECT: usage of flexible, metal hoses ensures installation of equipment in conduits of curvilinear configuration. 2 dwg
