摘要：

The accident scenario postulated in this study considers that the cryostat in the DEMO fusion reactor is filled with helium gas through cryogenic system primarily devoted to cool the magnets. Since the DEMO cryostat is designed as a thin-walled structure, over-pressurization would cause its buckling and potential collapse. For this reason, the cryostat boundary fails at the over-pressure of 5 kPa with opening of a rupture disk. A MELCOR model of the DEMO reactor is under development and will be used to predict this transient phenomenon and to assess the pressure and temperature values in the enclosures between the vacuum vessel and the cryostat.
