pressure reduction, equipment and pipelines, hydrostatic strength tests, nuclear power plantAbstract
The aim of the study is to determine the possibility of reducing the pressure of hydrostatic tests of nuclear power plant equipment and pipelines in the Russian Federation to reduce their damageability during operation. To this end, the article considers the Russian and foreign regulatory documents stipulating the procedure and parameters for conducting hydrostatic tests. The article also considers patents and articles addressing an analysis and experience gained from conducting hydrostatic tests of equipment and pipelines at nuclear power plants, in the petroleum and gas industry, in heat networks, etc. It has been shown from the analysis that around the world, various approaches to the choice of hydrostatic test pressure for equipment and pipelines are used, the value of which is in some cases lower than that for NPPs in the Russian Federation. There are also approaches to and positive experience gained from reducing the strength test hydrostatic pressure. Thus, the modern global trends and tendencies presented in the article confirm the need to improve the current regulatory framework stipulating the parameters of hydrostatic tests at nuclear power plants in the Russian Federation. The trends toward optimizing the hydrostatic test pressure confirm the relevance of carrying out further studies aimed at updating the hydraulic test parameters calculation methods. Updating of the regulatory framework of the Russian Federation in terms of reducing the pressure of hydrostatic tests at nuclear power plants will help reduce the damageability of equipment and pipelines at NPPs in the Russian Federation.
