В статье рассматривается обеспечение прочности и конструктивной целостности важных для безопасности пассивных элементов АЭС - трубопроводов и оборудования - при длительной эксплуатации энергоблоков АЭС. Рассмотрены методы определения фактических параметров нагрузки при монтаже, наладке и наладке оборудования. Применение метода акустоупругости, обеспечивающего измерение механических напряжений, возникающих в результате технологических операций, позволит выявлять неявные предварительные нагрузки при установке и оценивать их влияние на обеспечение проектного ресурса трубопроводных систем, в том числе установленного оборудования. Даны рекомендации по применению метода акустоупругости на строящихся блоках АЭС в первую очередь. На указанных выше объектах применения метода акустоупругости при сооружении энергоблока №1 Курской АЭС-2 (САОЗ, КС, трубопроводы пара и питательной воды) в настоящее время в соответствии с аттестованной методикой измерений (СМП). выявить неявные предварительные нагрузки при установке можно только при температуре не выше 55°C. Мониторинг фактического уровня нагрузки в состоянии «как построено» будет надежной гарантией безопасной эксплуатации трубопроводов Курской АЭС-2 по критериям прочности и конструктивной целостности.
