Keynote Speakers 

Luis Enrique Herranz

Head of Nuclear Safety Research at CIEMAT

Luis Enrique Herranz  has been a Research Professor since 2015. He has been leading the Unit for Nuclear Safety Research for more than 20 years. He has published more than 150 papers in refereed journals and has made more than 300 contributions in international conferences and workshops.

Since 2019, Luis has been the leader of the Technical Area 2 (Severe Accidents) of SNETP/NUGENIA and was the Chair of the WGAMA (Working Group of Analysis and Management of Accidents) of OECD/NEA between 2016 and 2021. With a strong commitment to teaching and training, he regularly lectures in national and international graduate and postgraduate courses.


Ana Gomez Cobo

Head of Safety Assessment at International Atomic Energy Agency

Ana Gomez Cobo has been working in nuclear safety for over 34 years. From 1995 to 2000 she worked for the International Atomic Energy Agency (IAEA) where she was a technical officer responsible for activities on probabilistic safety analysis, safety performance indicators and safety-related maintenance for nuclear power plants.

Ana joined the Office for Nuclear Regulation (ONR) in 2000 where she has undertaken specialist assessment and project inspection work related to UK's operating reactors and new nuclear build.
