Assessment of the Tornado Impact on the Chernobyl New Safe Confinement

Abstract

Проверка конструкций на воздействие торнадо для объектов атомной энергетики яв-ляется обязательной процедурой. Эта проверка выполнялась при проектировании Нового безопасно-го конфайнмента над разрушенным энергоблоком Чернобыльской атомной станции (NCC ChNP). Размеры и геометрическая форма этого объекта сильно отличаются от обычных сооружений, для ко-торых накоплен определенный опыт расчетов на действие торнадо. Это привело к необходимости поиска соответствующих приемов расчета. В статье приводятся детальные сведения относительно выполненных расчетов и отмечаются решения, принимавшиеся при недостатке необходимой инфор-мации в запас надежности. Опыт выполнения расчетов, связанных с учетом возможной нагрузки от торнадо на это уникальное сооружение, может представить определенный интерес. Целью этой работы является анализ накоп-ленного опыта. Речь идет о решении двух сложных задач: • установка параметров торнадо, которые должны быть приняты для проектирования; • разработка инженерной методики расчета на действие торнадо. В статье рассказывается о том, как упомянутые задачи решались на практике. В дополнение к описанию использованных приемов расчета сформулированы вопросы, которые следовало бы уточ-нить при проведении аналогичных проектных работ.

All the nuclear facility structures must be analyzed for tornado loads. This analysis was per-formed when designing the New Safe Confinement over the ruined Chernobyl power unit (NSC ChNPP). The standard methods of tornado analysis could not be applied due to its large size and geometric shape. Therefore, it was necessary to develop new calculation methods. The paper provides detailed information on the performed calculations and describes the conservative assumptions made when there was not enough information. The purpose of this paper is to analyze the gained experience of performing such an analysis of this unique structure, which may be of some interest. The following two complex problems are considered: • establishing the design tornado parameters; • developing an engineering methodology for the tornado analysis. Moreover, questions are formulated that should be clarified when carrying out similar designs.
