Ensuring of safe and reliable operation of nuclear power plants equipment must be based on making decisions on risk management throughout its life cycle.

The pipeline system of power units, working in conditions of flow-accelerated corrosion (FAC), significantly affects the quality, cost and safety of the nuclear power station in whole.

On this point reliable and long-term practice of observations, as well as application of sophisticated mathematical methods of forecasting, based on physical or empirical models of the investigated process is important.

In this regard there is an urgent need for creation of Russian analytical software with a common structured database of performance characteristics conducting reliable calculation of FAC process intensity as well as determining the residual life of equipment elements.

Such computer system should not concede to analogues in the possibilities of ergonomics and process orientation, but should take into account the specifics of Russian nuclear industry and experience of research in the field of designing analytical models for the prediction of the equipment life.

The article is devoted to the description of scientific and practical researches on creation of decision support system on the management of the life of NPP equipment.

The test model of the application solves the tasks of regular pipes wall thickness control data collection and storage mathematical prediction of the FAC speed and determination of residual life of nuclear power plant pipelines elements.

The system is intended primarily for the personnel of the nuclear power station, so it is developed with use of modern algorithmic and software tools to ensure a safe and comfortable work with a common database in the mode of "one window".
