Abstract
An analytical method has been developed and verified by three-dimensio nal elastic-plastic finite element analyses to evaluate stress intensi ty factors for finite length through clad and subclad cracks in reacto r pressure vessels (RPV) under loss of coolant accident conditions. Th e method is applied to thermohydraulic transients of the RPV of KKS. T he results demonstrate the margin of safety for the RPV for end of lif e material conditions. (C) 1997 Elsevier Science S.A.
