In conditions of increasing requirements for the reliability, safety and durability of power units, technical diagnostics systems are beginning to come growingly into use, having evolved, in the process of their development, from simple indicator systems to complex software and hardware systems (SHS) that require nontrivial skills and diverse knowledge to operate. The final information provided by an SHS is specific and comprehensible only by personnel of the NPP’s diagnostic departments, this complicating both the operation of diagnostic systems and discredits the very concept of early and timely detection of defects. This paper presents the structure of information flows in modern technical diagnostics systems (TDS),as applied to the innovative VVER-1200 power unit, on the example of Novovoronezh NPP, and diagnostic results in the form of regular reporting forms with generalized information about the serviceability of the TDS components and the system as a whole. The information received from technical diagnostics systems is analyzed in detail, and the concept proposed by the authors is considered for compression of diagnostic information into a form which can be easily conceived by operating personnel and is of a universal nature, with the possibility of being placed on an electronic or paper carrier.
