Spanish contribution to the development and application of probabilistic safety analysis: Experience and future challenges

Abstract

[EN] The development of Probabilistic Safety Analysis, which began in Spain in 1986, is based on the document "Integrated Program on Development and Use of Probabilistic Safety Analysis in Spain" adopted by the Spanish regulatory body. A second edition of this document in 1998 considered the activities needed to apply its principles in different fields. Since then, the Spanish regulatory body, universities and the nuclear industry have contributed to their development and application, especially in nuclear power plants. This paper provides an overview of the Spanish experience in three areas: the regulatory framework, developments, and applications. We also provide information on opportunities for improvement and future challenges.
