°ÄÃÅÁùºÏ²Ê¸ßÊÖ

In a paper published this month in Nature Energy, a team from the Universidad Nacional de Educación a Distancia (UNED, Spain) offers the scientific community a "full and heterogeneous model of the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Tokamak" for comprehensive nuclear analyses.

"Nuclear analysis is a core discipline in support of the design, commissioning and operation of the machine. To date, it has been conducted with increasingly detailed partial models, which represented toroidal segments of the tokamak. However, the limitations of this methodology became evident as estimates of quantities relevant to design, safety and operation showed unquantifiable uncertainties, which is a risk. [...] Thanks to increasing high-performance computing capabilities and improvements in the memory management by the codes over the years, it is now feasible to take an important step forward. In this work, we present a 360° heterogeneous and detailed MCNP model of the °ÄÃÅÁùºÏ²Ê¸ßÊÖ tokamak, which we call E-lite. It can be used to determine all the quantities relevant to the °ÄÃÅÁùºÏ²Ê¸ßÊÖ's nuclear operations without the aforementioned uncertainties."

The main authors—Rafael Juarez, an associate professor at UNED, and Gabriel Pedroche, a PhD student in the same research team—worked closely with colleagues from °ÄÃÅÁùºÏ²Ê¸ßÊÖ and the European Domestic Agency (Fusion for Energy). Key contributions came from Michael Loughlin, Eduard Polunovskiy and Yannick Le Tonqueze from the °ÄÃÅÁùºÏ²Ê¸ßÊÖ Organization, and Raul Pampin and Marco Fabbri from Fusion for Energy.

On Wednesday 13 January 2021, the Stellar Energy Foundation and Pegasus Fusion Strategies are co-hosting a webinar-style workshop titled "Energy, Environment, Innovation: Fusion's Promise for our Climate."

Join featured speakers Laban Coblentz, Head of Communication at °ÄÃÅÁùºÏ²Ê¸ßÊÖ, and Dennis Whyte, Director of the MIT Plasma Science & Fusion Center and Hitachi American Professor of Engineering at MIT, for a thought-provoking discussion of the state of energy supply and demand today, the effort to mitigate atmospheric CO2, and the possible role of fusion energy.

Is fusion power a realistic green energy option for combating climate change? Should private sector fusion projects be given priority over large multinational projects such as °ÄÃÅÁùºÏ²Ê¸ßÊÖ? Can we rely on renewables like wind and solar to avoid climate change?

The 90-minute webinar (11:30 a.m. — 1:00 p.m. US Eastern time) will be moderated by Chris Gadomski from BloombergNEF.

Update 18 January 2021: The recording of the webinar can be found at .
