Analysis of the computing methods of structural reliability of process flow diagrams for the power generating units of nuclear power plants

Abstract

Рассмотрены методы расчёта надежности сложных технических систем, позволяющие определять вероятность безотказной работы оборудования энергоблоков АЭС: метод перебора состояний, методы минимальных путей и минимальных сечений, метод расчета надежности, основанный на разложении относительно "особого" элемента; метод построения "дерева отказов". Проведен сравнительный анализ методов расчета надежности, приведены формулы расчета вероятности безотказной работы элементов логико-структурных схем объектов исследования.This paper gives consideration to the methods used for the computation of the reliability of complicated engineering systems that allow us to specify the probability of failure-free operation of the equipment used by the power generating units of NPP, in particular the enumerating technique of states, the methods of minimal ways and minimal cross-sections, the reliability computing method based on the expansion of a relatively ″special″ elements, and the ″fault tree″ construction method. The reliability computing method based on the enumerating technique of states is grounded on the logic algebra tool and uses the computing methods of the reliability indices of series, parallel and combined connections in bridge circuits
