On Jan. 26, 2022, researchers at the National Ignition Facility (NIF), in the Lawrence Livermore National Laboratory, claimed that fusion results published in their recent paper had achieved the fusion milestone known as “burning plasma.”

Philip Ball, an experienced U.K. science reporter, announced the news as a “Major Milestone toward Practical Fusion Power,” in a Scientific American article today.

According to Philip Ball, the reaction, which lasted a billionth of a second, is "on the cusp of being self-sustaining."

According to Philip Ball, the reaction, which lasted a billionth of a second, is “on the cusp of being self-sustaining.”

For fusion physicists, “burning plasma” refers to the state when the fusion fuel is heated primarily from self-heating, without an external source of heating.

From a practical perspective, the NIF experiment reported on Jan. 26, 2022, as a Reuters article explained, produced “about the equivalent of nine nine-volt batteries.”

Reuters did not explain, however, that the experiment required the equivalent energy of about 21,176 nine-volt batteries. Neither did Scientific American.

Even though the NIF experiment demonstrated a burning plasma, the fusion device lost 99.9 percent of the energy it consumed. Also, it lasted for just one-billionth of a second.

An Aug. 8, 2021, experiment at NIF did slightly better. It only lost 99.7 percent of the energy it consumed.

 

#102 Why Scientific Breakeven Is Not Relevant to Practical Laser Fusion Progress

A Jan. 26, 2022, Associated Press article about fusion results achieved at the National Ignition Facility (NIF) provides an excellent example of why achieving scientific breakeven is irrelevant to practical laser fusion progress.

NIF is part of the Lawrence Livermore National Laboratory, a U.S. government facility operated by contractors including Bechtel National, Babcock and Wilcox, and Battelle.

The AP, based on information published by the lab, told readers that the NIF experiments “pushed energy output to 1.3 megajoules … but even that is shy of the 1.9 megajoules needed to breakeven.”

The AP did not explain to readers that four types of gain measurements are used in the laser fusion research field. Only fusion scientists likely would be aware of the first three.

Instead, the public is generally aware of only the fourth: when the energy going into a fusion device equals energy produced by a fusion device. This is the only gain measurement where breakeven has practical meaning.

To achieve breakeven in the way the public understands — and in fact, would expect — the NIF device would need a fusion energy yield of 400 megajoules, not 1.9 megajoules, as the AP reported.

Pitching the President

With a loss of 99.7 or 99.9 percent (depending on the calculation used) of energy consumed by NIF, laser fusion is far from becoming a practical source of energy.

But that didn’t stop Andrew Holland, the chief executive officer of the Fusion Industry Association, from telling President Biden’s Council of Advisors on Science and Technology on Jan. 21, 2022, that NIF was among the fusion projects “on the cusp of a key milestone: net gain energy, more energy out than in.”

 

 

#101 How Fusion Scientists Misled the European Union About ITER

Feb 012022

  • ITER, funded primarily by European taxpayers, is an experimental fusion reactor that will consume more power than it produces — if it works as designed.
  • Fusion scientists have always known that ITER will not demonstrate that fusion is a source of energy.
  • But that’s not what they told the European Commission 22 years ago.

A few months ago, New Energy Times learned how European fusion scientists convinced the European governing bodies to fund the International Thermonuclear Experimental Reactor, ITER.

The scientists (we don’t know exactly who yet) provided false information to former European Commissioner for Research Phillipe Busquin. In turn, Busquin provided that information to the European Commission, the European Council of Ministers’ and European Parliament.

The European Union agreed to participate in the ITER project in 2000. In a Sept. 22, 2021, e-mail to New Energy Times, Busquin explained the history:

I submitted the project to the Commission in 2000 (the Directorate-General for Research), and they agreed to support ITER. ITER was presented as part of the fusion research supported by the EU. At that time, the budget was estimated at €5 billion, compatible with the budget of the EU’s framework programme for research.

Then, at the Council of Ministers on Nov. 16 2000, I put forward a technical proposal enabling the EU to take part in the ITER negotiations. I made it plain that the Commission was not conjecturing whether or not ITER should be built. However, the audience was silent. I realized that almost no one knew about ITER. Only the Swedish Minister followed suit and encouraged the EU to commit to ITER. After the meeting, during the informal lunch, I returned to discussing the fusion project, and almost everybody agreed with the proposal.

Afterward, I presented the project at a meeting of the Industry, Research and Energy committee of the European Parliament, and they were very supportive.

There was no public debate organized on this topic. This is normal because ITER was presented as a research activity within the existing framework programme.

Busquin told New Energy Times that he no longer had a copy of the proposal he presented. However, New Energy Times located a March 11, 2002, report written by Busquin’s spokeswoman, Andrea Dahmen, showing that Busquin told the ministers that the purpose of ITER was to build a fusion reactor “capable of producing energy at an industrial scale, 1,500 MW.”

This means that the fusion scientists advising Busquin did not explain several things to him.

First, they did not explain to him the input power rate, the power ITER was expected to consume. They didn’t explain to him that the ITER design specification (at the time) for a 1,500 MW thermal output, was a projected gross output power value. They didn’t tell him that the input power required to operate the reactor was about 500 MW. They didn’t explain to him that the gross thermal output, if the 1,500 MW would be converted to electricity, would be 600 MW. Had they done so, Busquin would have told his colleagues in the European governing bodies that the original ITER design specification was a fusion reactor “capable of producing energy at an industrial scale, 100 MW.”

The next thing the fusion scientists did not explain to Busquin was that, by March 2002, the 1,500 MW plan was already obsolete. The reactor design had, seven months earlier in August 2001, been scaled down in size and cost, from 1,500 MW to 500 MW gross thermal output. This reduction means that ITER is now designed as a reactor design that will be capable of CONSUMING power at an industrial scale, 100 MW. (These are simplified values. For full details, please see the New Energy Times ITER power value research.)

Of course, technically speaking, ITER, as a reactor system, was never intended to produce net power or produce energy at an industrial scale. It’s just a science experiment to study a fusion plasma. But that’s not how ITER was sold.

New Energy Times spoke with Busquin, 81, on Oct. 26, 2021, and explained the power information to him and asked for comment. The research was too far in his past, he said, and he could not remember the details.

In the years he was Commissioner for Research, he was the most enthusiastic political supporter of fusion in Europe. Busquin told us that he still has great hope for the dream of clean, limitless, abundant fusion energy on earth. That, however, was before we learned that the required fuel sources for nuclear fusion do not exist.

 

 

 

#100 Fusion Workers in Europe Suffer From ITER Management Issues

European workers on the International Thermonuclear Experimental Reactor (ITER) have complained through their unions that a culture of overwork, stress, and abusive management has led to illness among workers and an employee’s suicide, POLITICO.EU reported on Jan. 26.

The European contribution to the ITER fusion reactor project is managed by the ITER domestic agency known as Fusion for Energy. The agency operates under the leadership of Director Johannes Schwemmer.

The European Parliament’s Budgetary Control Committee held a preliminary hearing on the issues on Jan. 25 (link to video), and according to an administrator for the Parliament, the matter has been placed on the agenda for another meeting of the committee.

POLITICO.EU reported about the suicide:

The most fraught issue is the May 2021 suicide of plasma unit engineer Mario Gagliardi, who blamed stress at work for his decision to take his own life in a final note shared with POLITICO with his family’s permission.

“My final gesture is due to a breakdown at work, into which I have invested a lot … On a whirlwind of events I found myself to be the scapegoat of an unsustainable situation for years, despite my efforts and commitment to try and straighten things out from the bottom as much as possible, albeit unsuccessfully,” he wrote.

Chiara Merola, Gagliardi’s then-fiancée who also works at F4E, declined an interview but authorized POLITICO to share excerpts of her protest letter to management.

“I testified that his managers and HR were absolutely informed about his huge workload, about the episodes of harassment and bullying, about the attacks, about the risk of burnout, about the extremely stressful situation in which he was continually blamed for something that was not even his fault or responsibility and how all that was affecting his health,” Merola wrote.

On Jan. 17, 2022, the heads of the three labor unions representing the European ITER workers sent a letter to the European Commission about the critical situation in the Fusion for Energy agency. New Energy Times has obtained a copy of this letter. Among their greatest concerns was that the European Commission launched a preliminary assessment of the events that led to the death of Gagliardi — in collaboration with Fusion for Energy. The unions demand an independent investigation.

Schwemmer has a history of making false and exaggerated claims about the purpose and design objective of the ITER project. In September 2020, Schwemmer and his organization removed such false claims only after being forced by European Commissioner Kadri Simson, at my request, to do so.

 

 

#99 News Media Report Year-Old Fusion Breakthrough, Milestone, Step Forward, Etc., Etc.

Today, media organizations like Reuters reported “Researchers Achieve Milestone on Path Toward Nuclear Fusion Energy.”

That’s because the journal Nature published year-old results from laser fusion experiments performed at the National Ignition Facility (NIF) in Livermore, California.

In the experiments reported in the paper, researchers reported a fusion energy yield of 0.17 megajoules.

Omar A. Hurricane, the chief scientist for the inertial confinement fusion program at the lab, explained to New Energy Times that these experiments took place between November 2020 and February 2021.

The fusion energy yield from those experiments was eight times lower than the yield achieved later, in August 2021. That’s when the lab announced, in a press release, that it had performed an experiment on Aug. 8, 2021, that achieved a yield of 1.3 megajoules.

As we reported last August, the NIF device consumed 400 megajoules of energy and produced 1.3 megajoules.

Overlooking the input energy consumed, Reuters implied that the experiments produced a useful but small amount of energy: “The energy produced was modest — about the equivalent of nine nine-volt batteries of the kind that power smoke detectors and other small devices.”

These experiments lost 99.7 percent of the energy that the overall system consumed. They lasted for only a billionth of second. Nevertheless, that didn’t keep most of the news media from reporting that this older, less-powerful result was a “record-breaking” “milestone,” a “breakthrough” and a “step toward practical nuclear fusion.”

Sometimes in nuclear fusion news, a step backward is a step forward
