The aim of this report was to identify and analyse components and scenarios that could lead to oil fires in turbine building 3 at Ringhals nuclear power plant with the help of a study of fires in turbine buildings, interviews with experts at Ringhals and a statistical analysis of reported oil leakage. Consequence calculations were also conducted in order to see if the safety ambitions for the turbine building could be maintained during a pool fire. The reasons why the report focused on oil fires in turbine buildings are that international accident statistics have shown that fires in turbine buildings can lead to severe consequences and that oil is the major fire hazard in turbine buildings. The main identified problem areas were spontaneous ignition caused by autoxidation, vibrations from the turbines that for example can lead to turbine blade failure, high pressure and high temperature in the oil systems. The purpose with the report was also to suggest solutions on how to minimize identified risks regarding oil fires. The following suggestions should primarily be considered; an increase and improv...
