From 19 to 25 November 2020, an independent expert panel reviewed EUROfusion's R&D and design work on DEMO, Europe's future demonstration fusion power plant. Following this in-depth review, the next step of the European Roadmap to Fusion Energy, the conceptual design phase, can begin.

EUROfusion is taking a staged approach to designing DEMO, with industry-standard review practices including a gate review process. Each project phase is reviewed by a panel of independent experts before the project can advance to the next phase. This allows the DEMO team to learn from the experience of ITER and guarantees that DEMO has the support and involvement of the European fusion community and the companies that will design and construct it.

The International Atomic Energy Agency (IAEA) and the European Fusion Education Network (FuseNet) are calling on fusion enthusiasts around the world to review scientific literature and online resources to find as many zero-dimensional, or independent, design parameters as possible for active fusion tokamak and stellarator experimental reactors in the IAEA's interactive Fusion Device Information System (FusDIS) database. The data collected through the challenge, which is aimed at students and young professionals with an understanding of fusion without being experts, will prove useful for simulations, modelling and design studies to advance fusion research.

The challenge is looking for submissions that include the following parameters: radii, plasma current, magnetic field strength, material composition of device wall and divertor, plasma shape, elongation and triangularity.

Participants have until 31 January 2021 to submit their answers here.

A new fusion documentary follows the efforts underway at ITER, JET, and First Light Fusion to realize "the ultimate energy solution."

Produced by Bigger Bang Communications (UK) and narrated by actor Patrick Stewart (known for his distinct voice), the 60-minute film is part of a six-part series called Engineering the Future. "A global industrial revolution is underway, driven by passionate, dedicated individuals intent on shaping a new world. A cleaner world. A greener world. Together, they are pushing engineering to its limits to create extraordinary machines that can protect our planet for the future."

The episode on fusion can be viewed on Curiosity Stream and HBO Max (paywalls).

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 ITER 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 ITER tokamak, which we call E-lite. It can be used to determine all the quantities relevant to the ITER'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 ITER and the European Domestic Agency (Fusion for Energy). Key contributions came from Michael Loughlin, Eduard Polunovskiy and Yannick Le Tonqueze from the ITER Organization, and Raul Pampin and Marco Fabbri from Fusion for Energy.

Javier Santaolalla is a Spanish engineer and doctor in particle physics who has worked at CIEMAT, CERN and the French National Centre for Space Studies. On YouTube you can look him up as a scientific popularizer with a number of well-followed channels that tackle physics, explaining concepts like black holes, the Higgs boson and the second law of thermodynamics in an entertaining and informative way.   In December, he released a 16-minute feature on ITER (ITER: Así será el mayor reactor nuclear del planeta) that has reached 375,000 views.   You can watch it (in Spanish) here.
