Kiporenko A. The improve of the normative providing of nuclear power plants pipeline systems safety

The aim of work consists in the construction of the normatively-methodical providing on operating safety of the pipeline systems of the atomic stations on the basis of development of scientifically-reasonable mathematical model and algorithm of prognostication of remaining resource at the different types of ladening. A research object is a process of providing of operating safety of the pipeline systems of nuclear power plants. The article of research is normatively-methodical documentation on exploitation of pipelines . Research methods - theoretical and experimental. The theoretical is based on modern positions of theory of standardization, fundamental positions in area of, theory of the systems dynamics and durability. Experimental researches are based on the use of modern measuring apparatus, statistical treatment these and approved engineering methodologies. On the basis of analysis and aggregate data, methods and methods of estimation of the state of the pipeline systems NPP, the algorithm of prognostication of their operating safety is worked out at the different types of ladening and accordingly normatively-methodical providing. A novelty is based on next scientific developments: 1. Classification of pipelines, systematization of them on the classes of safety, environment of теплоносителя and different types of ladening, NPP that allowed to perfect кодификатор of the pipeline systems.2. To the mathematical model of calculation of remaining resource of pipelines of АЭС which in a difference from existing, takes into account the changes of thickness of wall of pipeline at the action of vibration, that allowed to increase authenticity of prognostication of resource. 3. Improved method of calculation of remaining resource of pipelines of АЭС, on the basis of construction of calculation certainly-element model which allows to model the degree of imperfectness from an erosive-corrosive wear and work out the incremental algorithm of estimation and prognostication remaining resource.4. System of normative data, which includes the models of calculation of remaining resource, crooked dependences of tension of metal of pipeline in the process of exploitation of pipeline and standardization of supports at the different types of ladening in obedience to classification of pipelines, that plugged in the worked out standard of NNEC "Energoatom" of Ukraine.
