Methodological efficiency of reactor pressure vessel control samples programs and reliability of WWER vessels at the Ukraine NPP

  • 1. NAEhK Ehnergoatom, Kiev (Ukraine)

Description

An analysis is made for the programs with the use of check specimens (CS) for reactor vessel (RV) control which is considered as the only method for estimating embrittlement in RV material and its operational capability. Advantages and disadvantages of the programs are noted. Other methods are developed and improved to estimate properties of RV metal and welded joints. It is shown that the most valid information about RV metal state can be obtained only by testing specimens prepared from templets cut directly from a RV wall in the region of reactor core. Ukrainian researchers designed the equipment and performed successful tests on templet cutting from the surface of the metal to study mechanical properties of critical pipelines

Abstract (Russian)

Проанализированы программы образцов-свидетелей (ОС) корпуса реактора (КР), считающихся единственным способом оценки степени охрупчивания материала КР и определения его работоспособности. Отмечены их преимущества и недостатки. Разрабатываются и совершенствуются альтернативные методики оценки свойств металла КР и сварных соединений. Показано, что наиболее достоверную информацию о состоянии металла КР могут дать только испытания образцов, изготовленных из темплетов, взятых непосредственно из стенки КР в районе активной зоны. Исследовательскими коллективами Украины разработано оборудование и проведены успешные испытания по отработке методики вырезки темплетов с поверхности металла для исследований механических свойств ответственных трубопроводов
