The paper introduces the European Union funded cooperation between the Brazilian nuclear regulatory body (CNEN) and a consortium of several European organizations. The still ongoing cooperation started in 2011 and has provided CNEN with insights and complementary information for licensing and regulatory activities on different reactor nuclear safety issues. The support is described by examples relating to the Severe Accident Management Program (SAMP) of the Angra 2 nuclear power plant NPP and the safety of digital instrumentation and control systems (DI&C) of Angra 3. The goal of the support regarding the SAMP is the review of the SAMP - under the licensing process by CNEN ??? with the focus on the new procedures and equipment implemented after the Fukushima accident. In parallel, a MELCOR simulation model of Angra 2 has been developed to perform independent calculations in order to support the assessment of the safety analysis presented in the Angra 2 Severe Accident Management Guides (SAMG). The support regarding DI&C is focused on regulatory issues concerning the review and assessment of digital instrumentation and control systems (DI&C) of the Angra 3 NPP under the licensing process by CNEN ??? providing CNEN with insights and complementary information on licensing experiences of new reactors with a DI&C architecture and technology similar to that of the Angra 3 NPP.
