The essence of the project - determination of the parameters of the AE signals, generated during fracture of vessel steel, and specifics of the AE-sensor placement for AE source location. Using the obtained experimental data, the schematic concept for the system and its modules has been developed and a sample of telemetric multi-channel portable AE system has been designed and produced. The system is purposed for telemetric AE health monitoring of the dangerous equipment. Key words: crack, fracture, acoustic emission, reactor vessel, technical diagnostics.
