Effect of high temperature on integrity of pressure vessels of nuclear power plant in case of severe unusual accident

摘要：

The effect of temperature on material properties and structural stress of a cylindrical vessel is studied in this paper. The maximum pressure considering the thermal stresses and large strains is derived for power-hardening law materials. Research results indicate that the temperature above 300 °C will greatly reduce the integrity of vessels. A brief explanation on Fukushima nuclear accident is performed based on the simple numerical estimation by the proposed method.
