Accident Risks in the Energy Sector: Comparison of Damage Indicators and External Costs

In 1998 ENSAD, a highly comprehensive database on severe accidents with emphasis on the energy sector, was established by the Paul Scherrer Institute (PSI). The historical experience represented in this database was supplemented by probabilistic analyses for the nuclear energy, to carry out a detailed comparison of severe accident risks in the energy sector [1]. The database allows to perform comprehensive analyses of accident risks, which are not limited to power plants but cover full energy chains, including exploration, extraction, processing, storage, transports and waste management.
