On the calculation of dynamic stresses in reactor supporting structures

Creators

Description

The problem of calculating NPP equipment reliability at maximum credible accident (instant blowdown of the primary circuit pipelines) is considered. The solution to the problem is considered as applied to the system reactor-upper unit connected by supporting elements with concrete structures of the well. Basing on the analysis of calculation results exercised for a WWER-440 reactor it is concluded that the highest dynamical stresses in the vessel supports are developed in 0.2-0.53 after an accident
