Оцінка залишкового ресурсу корпусів парових турбін АЕС

Abstract

The experience of the operation of nuclear power plants allows us to substantiate the revision of earlier specified lifetime for the power units of nuclear power plants. In December 2016 the specified lifetime expires for the power unit No3 at the Rivne NPP equipped with the reactor of a BBEP-1000 type and the turbine К-1000-60/3000 and the residual life of the equipment must be evaluated to provide a reliable operation for new power units and the reduction of the expenditures for putting them into the operation. The purpose of this scientific paper is to extent the operation life for the power equipment. For structurally complicated HPC casings three-dimensional structures with horizontal flanges, steam supply pipe branches and other elements are taken into account. The methods were developed to create dimensional analogues of the elements of turbine machines using Solidworks software product for the HPC casing. The geometric model was constructed on the basis of the certificate drawing for the К-1000-60/3000 turbine.
