Description

Paper deals with the results of the parametric calculation of thermal and strength behaviour of the WWER-440 reactor vessel under the accident beyond the design basis. Paper presents the ranges of the vessel excessive pressure and the conditions of surface water cooling of reactor permitting long-term melt confinement in the reactor vessel in case of severe accident

Abstract (Russian)

Приведены результаты параметрических расчетов термопрочностного поведения корпуса реактора ВВЭР-440 при запроектной аварии. Представлены диапазоны избыточного давления в корпусе и условия наружного охлаждения реактора водой, при которых возможно длительное удержание расплава в корпусе реактора при тяжелой аварии
