About the "GIF Education and Training" Webinars

These webinars, organised by the GIF Education and Training Working Group are streamed live monthly. The recordings and slide decks are accessible after the webinar on this website. These webinars cover a very broad range of technical and policy related topics. At the end of 2023 they have been viewed by more than 15000 people (approximately half of the views during the live streams and the other half views being of the archives on the public GIF website). In total, the GIF webinars have reached Generation IV enthusiasts, scientists, and engineers in more than 80 countries.

These webinars are organised and hosted by the GIF Education and Training Working Group (ETWG). 

About this Webinar

Sponsored by the United States Department of Energy (DOE), the NEAMS program aims at developing advanced modeling and simulation tools and capabilities to accelerate the deployment of advanced nuclear energy technologies, including light-water reactors (LWRs), non-light-water reactors (non-LWRs), and advanced fuels. Using Molten Salt Reactors (MSRs)  as an application example, this webinar will provide an overview of the NEAMS tools for reactor physics, thermal-hydraulics, thermochemistry, and structural performance modeling and analysis. Finally, state-of-the-art modeling applications will be provided, showcasing multiphysics nuclear reactor modeling using NEAMS tools.

Dr. Patricia Paviet from PNNL, USA, member of GIF ETWG will facilitate this webinar.

Dr
Mauricio TANO RETAMALES

Scientist at the Nuclear Technology Division

Dr. Mauricio Tano Retamales is a scientist in the Nuclear Technology division at the Idaho National Laboratory. He leads efforts for the development and validation of multiphysics software under multiple DOE programs. Additionally, he routinely engages with nuclear industry stakeholders to improve nuclear reactor design and operation, which motivated some of the applications to be presented in this seminar. He has co-authored 80+ peer-reviewed publications, 30+ laboratory reports, 3 book chapters, and 2 U.S. patents. In 2018, he received his PhD in nuclear engineering from the Grenoble Institute of Technology, University of Grenoble-Alpes, France.

ETWG Webinars Lead

Dr. Patricia Paviet was the first chair of the GIF Education and Training Working Group (2015-2024). She now focuses on leading the efforts of the successful GIF Education and Training webinars series and has been doing so since the inception of this initiative in September 2016. 
She serves on the GIF MSR pSSC representing the United States since 2021. She joined GIF in November 2015, as chair of the Education and Training Task Force. Outside GIF, Dr. Paviet is the National Technical Director of the Molten Salt Reactor Program for the US Department of Energy, Office of Nuclear Energy. She is managing the research supporting molten salt reactor development across six U.S. national laboratories. She is also a Senior Technical Advisor at Pacific Northwest National Laboratory, providing guidance on used nuclear fuel recycling. She has an extensive technical background on the nuclear fuel cycle (front and back end).
