Fusion veteran Barabaschi selected as ITER director general

Capping a session in Paris, the ITER Council has unanimously selected Pietro Barabaschi as the new director-general of the ITER Organization. The Italian-born Barabaschi, who has been involved in nuclear fusion research for some 30 years, was chosen to lead the massive international fusion project following an intensive recruitment effort necessitated by the death of Bernard Bigot, the previous director general, in May. Since Bigot’s death, Eisuke Tada has been serving in the role in an interim capacity. Barabaschi will take office in October.

F4E leader: Barabaschi has been the head of the Broader Approach Programme and Delivery with Fusion for Energy (F4E) since 2008. F4E is the EU organization responsible for Europe’s contribution to ITER. In this position, he has been managing the department that oversees three projects stemming from the Broader Approach agreement between the European Atomic Energy Community (Euratom) and the government of Japan: the JT-60SA tokamak, the International Fusion Materials Irradiation Facility/Engineering Validation and Engineering Design Activities linear accelerator, and the International Fusion Energy Research Centre . Barabaschi has also been acting director of F4E.

The world watched as Queen Elizabeth II welcomed the U.K.’s Atomic Age

As citizens of the United Kingdom and others around the world mourn the death of Queen Elizabeth II, many have reflected on how the world has changed during the seven decades of the queen’s reign—the same decades that saw the rise of civilian nuclear power.

Calder Hall was already under construction at the Sellafield site in West Cumbria when Princess Elizabeth became queen in 1953. Queen Elizabeth traveled to the site in October 1956 and declared, in a televised ceremony, that “It is with pride that I now open Calder Hall, Britain’s first atomic power station.” Watch the fanfare in a historical clip uploaded to YouTube by Sellafield Ltd below.

A growing part of the fusion community

Fusion energy is no longer a far-off goal. It is now routinely achieved at laboratory scale but requires more energy to control the fusion reaction than the fusion reaction has released.

The path to viable fusion power from a magnetically confined plasma source requires the creation of a burning plasma, whereby the primary heating source comes from the fusion reaction itself.

To begin to consider the economic viability of a fusion power plant, the reaction must have a significant energy gain, or “Q” factor (the ratio of output power to input heating power), in a reaction that is sustained over a time frame of minutes or hours.

Construction has begun on an international experiment—the ITER tokamak—that aims to achieve a sustained reaction, and numerous privately funded smaller experiments have the potential to move forward toward this goal.

Nuclear News reached out to companies in the fusion community to ask for insights into their ongoing work. All are members of the Fusion Industry Association. Most companies submitted briefs at a specified word count, while others ran long and some ran short. Their insights appear on the following pages.

Notes on fusion

Governments around the world have been interested in fusion for more than 70 years. Fusion research was largely secret until 1968, when the Soviets unveiled exciting results from their tokamak (a magnetic confinement fusion device with a particular configuration that produces a toroidal plasma). The Soviets realized that tokamaks were not useful as weapons but could produce plasma in the million-degree temperature range to demonstrate Soviet scientific and technical prowess to the world.

Following this breakthrough, government laboratories around the world continued to pursue various methods of confining hot plasma to understand plasma physics under extreme conditions, getting closer and closer to the conditions necessary for fusion energy production. Tokamaks have been by far the most successful configuration. In the 1990s, the Tokamak Fusion Test Reactor at the Princeton Plasma Physics Laboratory produced 10 MW of fusion power using deuterium-tritium fusion. A few years later, the Joint European Torus (JET) in the United Kingdom increased that to 16 MW, getting close to breakeven using 24 MW of power to heat the plasma.

A life in nuclear reactor physics and design

You may have read the abbreviated version of this article in the November 2020 issue of Nuclear News. Now here's the full article—enjoy!

I have enjoyed a long and stimulating career in applied nuclear physics—specifically nuclear reactor physics, nuclear fusion plasma physics, and nuclear fission and fusion reactor design—which has enabled me to know and interact with many of the scientists and engineers who have brought the field of nuclear energy forward over the past half-century. In this time I have had the fortune to interact with and contribute (directly and indirectly) to the education of many of the people who will carry the field forward over the next half-century.
