Abstract

The Spanish Regulatory Body (CSN), in coordination with Cofrentes NPP, contracted Iberdrola Ingenieria y Consultoria (Spanish Engineering Company) for carrying out a pilot experience to test the state-of-the-art methodologies on risk informing regulations regarding Special Treatment Requirements (STR) scope, i.e., to focus STR on more risk significant SSCs and allowing low safety significant SSCs not to be under such requirements. The project has been developed on two Cofrentes NPP systems under a two phase process: risk categorization of SSCs and STR scope analysis.
