Abstract

The paper is concerned with the analysis of the existing regulatory support, its systematization and development of common classification criteria of regulations aimed at ensuring nuclear and radiation safety in dealing with life extension of thermal and mechanical equipment of the reactor facility of nuclear power plants. A brief description of operating conditions of thermal and mechanical equipment of the reactor facility and the algorithm of execution of works for service life extension are presented. The analysis of data on standardization of processes in the energy sector in Ukraine and abroad, including industry standards is performed. The results have shown that existing regulations require the creation of systematization, which makes it possible to develop common rules for selecting the physical parameters that characterize the technical condition of equipment considering its degradation, improve methodological support for reliable assessment of the technical condition of equipment; systematize the results of surveys and calculations for determining the predicted residual life. The structural formulation of classification criteria of regulatory support will improve the regulations to identify or expand technical specifications that define the equipment degradation processes to justify the method of evaluating its current technical condition and residual life, taking into account the requirements of safe operation of nuclear power plants.
