【 摘 要 】

A major feature specific to commissioning of NPPs in Russia and of Russian-designed NPPs in foreign countries is a great deal of measurement involved at different pre-commissioning stages, which differs from foreign experience where emphases is placed on computational justification and the scope of in-situ commissioning testing is smaller. The use of various measuring systems in pre-commissioning operations requires the involvement of a large number of personnel from different organizations, infrequently with no data acquisition coordination among them. This leads to both measuring channels and the information gathered being multiply duplicated (assembly, installation, adjustment), which is one of the sources for its misrepresentation, and to a greatly increased cost of operations. At the same time, most modern power units are equipped with test systems (TS) [1–4] consisting of heterogeneous measuring channels. The current TS commissioning practice required systems to be adjusted and started up only after the 100% unit power level was reached which did not make it possible to use test systems at pre-commissioning and power ascension stages. This study is an attempt to create an integrated information system composed of heterogeneous local systems to enable the largest possible number of standard channels to be used simultaneously with temporarily installed channels for pre-commissioning measurements to provide sound and high-quality information on the state of the unit.
