Solving the problem of ensuring target life and overhaul-period renewal of NPP pipelines and equipment is an urgent problem of contemporary nuclear power engineering that demands system-wide approach, based upon FAC physic-chemical processes and regularities scientific investigations, creation of computer modeling techniques to predict flow-accelerated corrosion and as the result practical measures on NPP implementation.

           In recent years, on the basis of experimental investigations, the numerical model of flow-accelerated corrosion in single and two-phase flows RAMEK has been developped in Russia. It is based upon physic-chemical criteria modeling of FAC processes and includes modules to estimate local FAC parameters and criteria taking into account technological processes occuring in a NPP secondary coolant circuit.

           On the basis of RAMEK usage the concern "Rosenergoatom" developed and approved the comprehensive program, that includes software systems to support NPP staff's decision making development. The main aim of program implementation is to solve practical tasks of failures prevention, operational life prolongation and diagnostics and repair of pipelines cost saving.

He has been a researcher of flow-accelerated corrosion phenomena for more than twenty years and has more than 100 publications. Mr. Tomarov is the General Director of JSC "Geotherm-EM". Nowadays, the company takes an active part in "The comprehensive program of measures to prevent pipelines and power equipment breakdowns and increase operational erosion-corosion resistance in NPP secondary coolant circuit" realization in Russia.
