The main feature distinguishing commissioning as refers to nuclear power plants in Russia and Russian projects implemented abroad is the large number of measurements conducted during different phases of commissioning which is in contrast to the foreign experience where professionals focus more on the design rationale, and of fullscale testing is conducted at a smaller scale during the commissioning. Use of measuring systems for various purposes during commissioning requires involvement of large numbers of staff from different organizations, often not coordinating with each other their efforts aimed at the obtaining information. This results in the unwanted parallelism (mounting, installation, adjustment) both of measurement channels and of the information thus obtained, which ultimately serves as one of the sources of its distortion and results in the substantial increase of the cost of operations. At the same time, most modern power units are equipped with technical diagnostics systems (TDS) [3, 4, 6, 10] including in their composition measuring channels for various purposes. In pursuance with existing practice of TDS commissioning adjustment and startup operation of diagnostic systems is allowed only when the power unit level reaches 100% which prevents the TDS use during the phases of startup preparation operations and the unit power ascension. Distinguishing feature of the present study is the attempt to combine disparate local systems into a unified information system allowing use of the maximum number of standard channels simultaneously with dedicated measurement channels temporarily installed for the commissioning in order to obtain reliable and quality information about the status of the power unit.
