The aim of this work was to perform the real case study for the US Surry Nuclear Power Plant which was touched down by tornado in 2011 causing the electrical switch yard destruction and loss of offsite power. Probabilistic methods have been applied to assess the reliability of the reactor shutdown and effective heat removal after this accident. The reactor protection system and auxiliary feedwater system were thoroughly analysed in the context of their safety features designed to prevent the reactor core damage. The emergency power system reliability has been also considered due to the fact that some components of the safety systems are electrically operated. Moreover, time-dependent analysis has been performed in order to address the level of damages after an extreme external event like tornado. Depending on the severity of such events the time required to restore the electrical grid may be significantly different and longer than 24 hours. The reliability and requirements for safety systems are changing with time and these changes have been taken into account as well.
