U.S. Department of Energy Funds $10 Million to Study Low-Energy Nuclear Reactions
Top Universities Resuming LENR Research to Search For Potential New Energy Source

On Feb. 17, 2023, the U.S. Department of Energy issued the following press release and extended project descriptions:

WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today announced $10 million in funding for eight projects working to determine whether low-energy nuclear reactions (LENR) could be the basis for a potentially transformative carbon-free energy source. The teams selected today—from universities, a national laboratory, and small business—aim to break the stalemate of research in this space.“ARPA-E is all about funding high-risk, high-reward energy technologies,” said ARPA-E Director Evelyn N. Wang. “The teams announced today are set out to answer the question ‘does this area show promise, and if so, how? Or can we conclusively show that it does not?’ While others have shied away from this space, ARPA-E wants to break through the knowledge impasse and deepen our understanding.”The following teams have been selected to receive funding as part of the Advanced Research Projects Agency-Energy (ARPA-E) LENR Exploratory Topic:

  • Stanford University (Redwood City, CA) will explore a technical solution based on LENR-active nanoparticles and gaseous deuterium. (Award amount: $1,500,000)
    Extended description: Stanford University will explore a technical solution based on LENR-active nanoparticles and gaseous deuterium. The team seeks to alleviate critical impediments to test the hypothesis that LENR-active sites in metal nanoparticles can be created through exposure to deuterium gas.
  • Massachusetts Institute of Technology (Cambridge, MA) will develop an experimental platform that thoroughly and reproducibly tests claims of nuclear anomalies in gas-loaded metal-hydrogen systems.? (Award amount: $2,000,000)
    Extended description: Massachusetts Institute of Technology (MIT) proposes a hypothesis-driven experimental campaign to examine prominent claims of low energy nuclear reactions (LENR) with nuclear and material diagnostics, focusing on unambiguous indicators of nuclear reactions such as emitted neutrons and nuclear ash with unnatural isotopic ratios. The team will develop an experimental platform that thoroughly and reproducibly test claims of nuclear anomalies in gas-loaded metal-hydrogen systems.
  • Amphionic (Dexter, MI) will focus on exploring if LENR are produced in potential wells existing between two nanoscale surfaces by controlling metal nanoparticle (NP) geometry, separation, composition, and deuterium loading. (Award amount: $295,924)
    Extended description: Cathode structure and surface morphology are thought to be essential for LENR reaction rate. Amphionic proposes to optimize cathode design to form Pd-polymeric composites within which the Pd nanoparticle size and shape are varied, and the interfacial separation and geometry are controlled. Experiments will focus on exploring if LENR are produced in potential wells existing between two nanoscale surfaces by controlling metal nanoparticle (NP) geometry, separation, composition, and deuterium loading.
  • Energetics Technology Center (Indian Head, MD) will use electrochemical co-deposition of a deuterated palladium metal compound on a metal substrate conformed onto a plastic scintillator to establish and sustain LENR. (Award amount: $1,500,000
    Extended description: Energetics Technology Center will build upon past successes with co-deposition experiments using palladium, lithium, and heavy water together to create an environment in which LENR can occur. These electrolysis experiments decrease the distance from the cathode (location of LENR) to an electronic detector capable of detecting nuclear reaction products to give these experiments the best chance at reliably detecting nuclear
    reactions, if they are present.
  • Lawrence Berkeley National Laboratory (Berkeley, CA) will draw from knowledge based on previous work using higher energy ion beams as an external excitation source for LENR on metal hydrides electrochemically loaded with deuterium.

    Extended description: Texas Tech University will develop accurate materials fabrication, characterization, and analysis to attempt to resolve the physical understanding of Low-Energy Nuclear Reactions (LENR). Texas Tech will also provide advanced detection of nuclear reaction products as a resource for ARPA-E LENR Exploratory Topic teams.
  • University of Michigan (Ann Arbor, MI) will use a gas cycling experiment that passes deuterium gas through a chamber filled with palladium nanocrystalline samples. Variables will include temperature, nanocrystalline size, and laser wavelength. (Award amount: $1,108,412)
    Extended description: The University of Michigan proposes to systematically evaluate claims of excess heat generation during deuteration and correlate it to nuclear and chemical reaction products. The team plans to combine scintillation-based neutron and gamma ray detectors, mass spectrometers, a calorimeter capable of performing microwatt-resolution measurements of heat generation, and ab-initio computational approaches.
    The proposed research will experimentally and theoretically explore the origin and mechanisms of excess heat generation and LENR.
  • University of Michigan (Ann Arbor, MI) will provide capability to measure hypothetical neutron, gamma, and ion emissions from LENR experiments. Modern instrumentation will be coupled with best practices in data acquisition, analysis, and understanding of backgrounds to interpret collected data and evaluate the proposed signal. (Award amount: $902,213)

 

ITER Organization Denies Projections of 2030 for First Plasma

Jan 062023
 

By Steven B. Krivit
January 6, 2023

The ITER organization denies news reports that First Plasma will be delayed another five years, until 2030.

First Plasma has been a key milestone of the ITER project since its inception. It marks the moment when most of the construction on the ITER reactor is complete and experiments with test fuels — hydrogen and deuterium — can begin.

The French newspaper Les Echos reported the delay on Nov. 24, 2022. New Energy Times, based on information from ITER organization staff members who were not authorized to speak on the record, reported one year ago that the first experiments likely would occur in 2031.

Official Denial

New Energy Times asked Laban Coblentz, the head of communication for the ITER organization, whether the Les Echoes story was accurate.

“Statements like the one in Les Echoes,” Coblentz wrote, “or others talking about a ‘five-year delay to First Plasma,’ are neither official nor accurate and are somewhat misleading.”

Delay Factors

Factors for the delay include dimensional nonconformities in parts of the reactor sectors and design flaws in radiological shielding devices, as New Energy Times reported on Feb. 21, 2022. The ITER organization also identifies delays caused by Covid-19 and the Russian invasion of Ukraine.

In 2021, two French nuclear safety authorities, Institut de Radioprotection et de Sûreté Nucléaire and Autorité de Sûreté Nucléaire, told Bernard Bigot, the former ITER organization director-general, about the safety issues and defects. Bigot did not want to delay the schedule. He insisted that construction on the reactor should move forward and that the reactor sectors could be repaired inside the reactor chamber. The regulators did not agree. They told Bigot that he must not lower the sectors into the reactor chamber unless he can guarantee that the installed sectors can later be separated and removed. Bigot instructed his staff to lower the first sector into the pit.

On Nov. 21, 2022, Pietro Barabaschi, Bigot’s successor, in concurrence with the regulator’s guidance, said that the first sector will now be removed and repaired.

“Dealing with it in the pit on the module that has already been assembled would be enormously difficult. This means we have to lift out the installed module and disassemble it in order to proceed with the repairs,” Barabaschi said.

Roadmap

New Energy Times has not seen a more detailed ITER roadmap than the one published in 2012, and we continue to rely on this — adjusted for delays — as the most authoritative sequence of planned events. Click here to see the full roadmap as it was published in 2012.

The test-fuel experiments are slated to run for seven years, until scientists feel confident enough to add radioactive tritium to the fuel mixture. During this time, required components to the inner wall of the reactor will be added to allow the use of deuterium-tritium fuel.

After two years of running preliminary experiments with deuterium-tritium fuel, the team hopes to increase the input power and thus achieve the reactor’s maximum thermal power output performance of 500 megawatts and duration of 500 seconds. The reactor is expected to consume about 440 megawatts of electricity.

Full-power deuterium-tritium operation would therefore take place around 2040, which is 20 years before global production of tritium is expected to terminate.

Tracking the Delays

When the ITER project was approved by its international partners in 2007, the organization estimated that ITER would begin operating by 2017.

By 2012, official documents showed First Plasma pushed back to 2020.

In 2016, the ITER organization formally acknowledged that First Plasma was pushed back to 2025.

ITER Organization Confirms 440 MW Electrical Input Requirement for Reactor

Dec 232022

After six years, Laban Coblentz, the head of communications for the ITER organization, has confirmed to New Energy Times the accurate projected electrical input power requirement, 440 megawatts, needed for the ITER reactor.

We had asked Coblentz for this power value at the end of 2016, but he provided an ambiguous and inaccurate response. Through independent scientists, in the summer of 2017, we initially determined that the required electrical input power for the reactor was 300 megawatts, which we reported on Oct. 6, 2017.

440 MW

We later developed evidence that the projected required power rate was likely 440 megawatts. We determined this number based on our analysis of a graph published by Ivone Benfatto, the head of the Electrical Engineering Division for the ITER organization. Benfatto, however, did not respond to our request to clarify and confirm our analysis.

Earlier this month, we asked again. Under the direction of Pietro Barabaschi, the new director-general of the ITER organization, Coblentz confirmed that our analysis is correct.

The Falsehood

For many years, the common belief about the ITER reactor was that it is designed to produce 500 megawatts of thermal power while needing only 50 megawatts of electricity to operate.

This false understanding was the direct result of inaccurate and ambiguous claims by the ITER organization and other fusion experts.

For several years, New Energy Times informed Coblentz and Bernard Bigot, the former director-general of the ITER organization, about the false power claims on their organization’s Web site. Nevertheless, on July 28, 2020, under their direction, the ITER organization issued a press release claiming that, “if operated continuously and connected to the electric grid, [the 500 MW thermal output] would translate to about 200 megawatts of electric power, enough for about 200,000 homes.” (Source, Archive Copy)

 The Facts

The 500-megawatt thermal output value was accurate. But the 50-megawatt value was a misrepresentation. It refers to only the injected thermal power that will be used to heat the plasma. The ITER reactor is designed for a net power gain across the plasma, not across the entire reactor. The “50 MW” and “500 MW” values always were associated with the plasma gain, but Bigot and Coblentz had said or implied that those values were associated with the overall reactor.

The Walkback

The false claim that ITER is designed to produce enough thermal power, if converted to electricity, to power 200,000 homes was consistent with the organization’s public communication until Barabaschi took over. For at least a decade, the ITER organization had promoted the project on Twitter as “a large-scale scientific experiment that aims to demonstrate that it is possible to produce commercial energy from fusion.” In an e-mail to New Energy Times, Coblentz walked those claims back further.

“ITER’s plant-wide power balance is not directly relevant to the anticipated power balance of any future commercial fusion machine,” Coblentz wrote.

The Future

ITER is the most scientifically credible experimental fusion reactor on track to demonstrate the feasibility of large-scale fusion energy. As always, the public wants to know one thing: How close are we to practical fusion energy?

If ITER succeeds in its primary scientific goal, then the correlated result for the overall reactor will be a net loss equivalent to 220 megawatts of electric power.

Coblentz told New Energy Times that this is an unfair comparison because ITER is not designed for overall reactor power gain and because the design encompasses redundancies and additional test instrumentation that would not be used in a commercial reactor.

Perhaps ITER is not the way to a new, clean, unlimited source of nuclear energy.

 

Lawrence Livermore National Laboratory Committed Science by Press Conference. Why?

Dec 222022
 

By Steven B. Krivit

Why did the Lawrence Livermore National Laboratory commit “science by press conference”? Why did the lab grossly exaggerate so many things about the Dec. 5 result, as I explained in this video? Why did the lab rush to publicize its result before publishing a scientific paper, let alone submitting one?

“Science by Press Conference” From Wikipedia:

Science by press conference or science by press release is the practice by which scientists put an unusual focus on publicizing results of research in the media, in the form of press conference events or press release statements. The term is usually used disparagingly. It is intended to associate the target with people promoting scientific “findings” of questionable scientific merit who turn to the media for attention when they are unlikely to win the approval of the professional scientific community.

Premature publicity violates a cultural value of most of the scientific community, which is that findings should be subjected to independent review with a “thorough examination by the scientific community” before they are widely publicized. The standard practice is to publish a paper in a peer-reviewed scientific journal. This idea has many merits, including that the scientific community has a responsibility to conduct itself in a deliberative, non-attention seeking way; and that its members should be oriented more towards the pursuit of insight than fame. Science by press conference in its most egregious forms can be undertaken on behalf of an individual researcher seeking fame, a corporation seeking to sway public opinion or investor perception, or a political or ideological movement.

Ignition Omission: Understanding the National Ignition Facility Milestone

Dec 212022
 

We obtained the 400 MJ input value from the lab and reported it 16 months ago. For more information about the earlier story, please see this article.

This video explains:
  1. The actual device input energy that the Lawrence Livermore National Laboratory omitted in its December 2022 announcement.
  2. The real-world significance of fusion ignition/scientific breakeven.
  3. The gap between the ignition result and the energy needed for device breakeven.
  4. The extremely brief duration of the fusion reaction.
  5. Why the claims that fusion is an “unlimited, abundant” source of energy are not true.
  6. That one of the two required fuels for most nuclear fusion concepts does not exist.
  7. That there currently are no good ways to make tritium.
  8. Visually, how far away this fusion device is from becoming a practical source of energy.
