All rights reserved.As well as any other fuel and energy complexes (such as hydroelectric power stations, heat power plants, etc.) nuclear power plants (NPP) are subject to high statutory requirements of its operational acceptability. However, due to NPP operational association with likely far-reaching severe environmental, social, political, material, etc. consequences of potential nuclear and radiation accidents unconditional NPP safety assurance is of primary importance. In common practice of NPP designing and operation, the long-term objective of increasing NPP operational acceptability and the task to guarantee to meet strict requirements of existing federal rules and regulations throughout the entire period of NPP life cycle are considered separately. That leads to not taking into consideration aspects of boosting high NPP operational acceptability when aims of NPP safety assurance are to be fulfilled. And conversely, with the intention of enforcing efficient operational acceptability the obligatory NPP safety level is made on a priori grounds. The reason for the described above situation is insufficiency of methods aimed at comprehensive or even exhaustive estimation of interaction between economic and technological numerous factors the last of which occasionally could have nothing in common. In the article methods for increasing of NPP operational acceptability via selecting optimal strategies of NPP maintenance carrying out are presented. In addition to it the methods applying could also acts as an instrument to contribute to high capacity factor value. A distinctive feature of the proposed methods is that the boosting of NPP operational acceptability is supposed to be put into practice via contemporaneous, simultaneous guarantee of mandatory NPP safety level in any NPP configuration.
