Inyushev V. Method for investigation of reliability and efficiency of NPP frontal safety system on the stage of operation

The dissertation is dedicated to development of method for investigation of reliability and efficiency of NPP frontal safety system on the stage of operation. This method is a basic for developed technique for assessment of possibility for lifetime prolongation of NPP safety-significant systems.The methods for assessment of reliability parameters on the stage of operation are described. It is shown that non-parametrical as well as parametrical methods for reliability parameters investigation (estimation) could be used depends from initial information. The proposed method is grounded on precondition about possibility of durability parameter investigation through investigation of reliability parameters (failure flow intensification). The technique is developed and father monitoring for the invested object verify correctness of this approach.
