Integral Risk Impact on the Structural Makeup of the NPP System

An approach to developing the NPP system with the lowest integral risk determined according to the entire life cycle and the conjugate infrastructure is studied. The search for the optimal power series of reactors for the developing NPP system is formalized and presented as a multicriterion optimization problem: reduction of harm from various risk factors and construction cost for the specified system capacity. A solution is found with the aid of an evolutionary algorithm. Recommendations are made on the basis of the calculations for optimizing the power range of reactors that will make it possible to reduce the aggregate risk of NPP operation with different approaches to strategic planning.
