Optimization of major systems of economy and power leads to degenerate high dimensionality solutions. This very strong mathematical complicating. However it allows to consider the future development of power as teamwork of nuclear power plants (NPPs), power plants (PPs) on coal, PPs on gas. System optimization of parameters NPPs is for this purpose necessary.

If PP certain type has not entered into the optimal plan for development of a electric power system it by definition is nonoptimal and, hence, is noncompetitive.

NPP can enter into the optimal plan for development of an electric power system. Thus, if in locallyoptimal plans for development of a electric power system the power units placed earlier in operation (NPPs) after their work on some length of time interrupt loading execution (power supply) to “zero” for the term exceeding procedural works it testifies about nonoptimal the chosen parameters and operating modes. Such NPPs show competitiveness only on length of time when the electric power system allows them to bear loading.

If the power units placed in operation (NPPs) stop the work (are removal from operation) before design service life not for the reasons of «moral» obsolescence it testifies about nonoptimal the chosen parameters and operating modes. And it too testifies to insufficient competitiveness of these NPPs.

As the competitive can be considered NPP which was included into the optimal plan for development of a electric power system and has fulfilled without interruptions in a mode of execution of loading on power supply design service life.

The analysis of an optimality and competitiveness NPPs leads to following conclusions for Russia.

To this day in Russia any NPP, any nuclear technology of a nuclear fuel cycle (NFC) were not optimized by economic criterion in the fuel power complex system on purpose to create commercial NPPs and nuclear technologies.

As system optimizing calculations of power of Russia have shown, that studied variants fast NPPs (SVBR-100, BN-1200 (threecircuit), BREST-1200) were included not into all optimal plans there is a doubt in an optimality of these chosen parameters NPPs and them NFCs though difficult multiple parameters researches are conducted throughout decades.
