FIELD: physics.
SUBSTANCE: leak resistance inspection apparatus for fuel element enclosures includes two neutron detectors and two transformation and supply channels of neutron detectors, line and processor. Each transformation and supply channel consists of series differential transformer, current pulse amplifier, discriminator, count-code converter. Outputs of each neutron detector are connected to inputs of differential transformers. Output of count-code converter of each channel is connected to line, and its outputs are connected to input of processor with its output connected to PC.
EFFECT: high inspection efficiency and reliability.
