Evolution of regulatory requirements (historical perspective, feedback from nuclear accidents and international activities), innovative approaches to leverage resources and knowledge of the national regulators reviewing new reactor power plant designs.
This round table discussed some of the issues highlighted by the previous speakers, including the role of innovation and design in coping with severe accident initiators; nuclear power operation and safety challenges in future energy systems (load following, flexibility, smart grids, climate change); the back-fitting of advanced solutions in existing Gen II reactors (safety upgrades and long-term operation) andthe harmonisation of regulatory requirements and standardisation and evolution of new designs.
Panellists: Véronique Decobert (Westinghouse), Bertand de l'Epinois (AREVA), Henri Pelin (WNA), Jacques Pirson (GDF-Suez), Giovanni Bruna (IRSN) and Jim Gulliford (NEA)
Day II - Vendors' and research organisations' perspectives
Session II-1(a): Vendor perspectives
Vendors were invited to discuss innovations in reactor and fuel designs to address improved safety and economics. The discussion essentially addressed Gen III designs but also specific innovative features of Small Modular Reactors based on light water reactor technology.
In this session, research organisations including technical safety organisations (TSOs) supporting regulators discussed long-term developments that could lead to innovations for future advanced water-cooled reactors and designs and their fuel cycle (e.g. accident-tolerant fuels). An update on safety research for water-cooled reactors performed under the NEA's Committee for the Safety of Nuclear Installations (CSNI) was also provided.
Session II-3: Round table discussion and conclusion of the workshop
In this final round table, a broad discussion took place on the future evolution of water reactor technologies in the 21st century, and the role of water-cooled Gen III reactors vs. the Gen IV reactors currently under development. The panel also discussed possible innovations that might be game-changers for the nuclear power sector versus other generation technologies and associated R&D needs.
Moderators: Marc Deffrennes and Henri Paillère (NEA/NDD)
Panellists: Abderrahim Al Mazouzi (EDF/NUGENIA), Patrick Dumaz (CEA), Henri Pelin (WNA), David Powell (GE Hitachi) and Hongxing Yu (NPIC)
