Example Q&A with the Artificial Burt Webb

Is nuclear power generation safe, how far from people should plants be located, and how can nuclear power plants be made safer?

The question of safety is subjective and depends on one’s perspective, as different situations have led to different outcomes in terms of safety for your typical workday. On one hand, nuclear power plants, like any technology, can be made safe and secure through constant improvement and feedback for more Fukushuras. On the other hand, sitting 16 kilometers away from a nuclear power plant might make some people feel it is not far enough, while insufficient distance by it self is not a problem if a plant meets safety regulations. Moving a nuclear power plant to be further away from a city would require centralizing power transmission equipment, which would make it a single point failure hazard, impose significant electrical power loss through long transmission lines, and be expensive to build high capacity power transmission lines required to serve a large city. Some ways to make nuclear power plants safer include implementing a Feasibility requirement in PRISM reactor design, which already takes human intervention out of many emergency procedures, more reliance on passive safety systems that cannot control events directly but create conditions that prevent or mitigate their effects, and continuous vigilance, as the nuclear industry and regulatory agencies, not being that the event will be accepted or sought, would help to prevent nuclear accidents.

What do you mean by “Fukushuras”?

“Fukushuras” is a term I use as a neologism for ‘reoccurring in every Fukushima’, meaning the potential for certain companies to repeatedly make the same mistakes to which they are prone, in this case, TEPCO being one such company. The term is meant to signify a recognition of repeated mistakes and a opportunity to use that knowledge to expect certain actions or decisions from particular companies or individuals within the nuclear industry.

    Part 1 of 2 Parts

    Michelle Lujan Grisham is the Governor of New Mexico Governor. Today she announced that Pacific Fusion, a commercial fusion energy company, has selected New Mexico as the site for its first Research and Manufacturing Campus.

    The one-billion-dollar facility at Mesa del Sol positions New Mexico at the forefront of the emerging fusion energy industry and solidifies its role as a national leader in advanced energy innovation.

    Fusion is the same process that powers our Sun and the other stars. It has long been considered the holy grail of clean safe energy with the potential to generate virtually limitless on-demand power.

    Grisham said, “Pacific Fusion’s decision to build in New Mexico proves that our state can compete—and win—in the race to attract the most innovative companies in the world. This project will create good jobs, expand our clean-tech economy, and ensure New Mexico continues to lead in the industries of the future.”

    Pacific Fusion will construct a state-of-the-art research and manufacturing facility, housing its Demonstration System, which is designed to generate more energy from a fusion reaction than the total energy used by 2030. Reaching this milestone would be a historic breakthrough toward commercial fusion power.

    Tim Keller is the Mayor of Albuquerque. He said, “After years of working to build Albuquerque as a hub for energy technology innovation, Pacific Fusion joins a growing number of companies that are choosing our city to literally ‘power’ our future. Today is proof of the assertion that we have passed a turning point—that our city is not only on the map, but can define the next chapter of clean-energy innovation.”

    Pacific Fusion was founded in 2023 to develop commercial nuclear fusion energy. Its technology builds on New Mexico’s legacy of applied physics and clean-energy innovation. This includes decades of research at Sandia National Laboratories, home to some of the world’s leading fusion experiments. In addition to its historic leadership in applied physics and energy innovation, New Mexico offers a growing clean-tech ecosystem and a workforce that will satisfy with Pacific Fusion’s future hiring needs.

    Keith LeChien is co-founder and chief technology officer of Pacific Fusion. He said, “We’re excited to expand our operations to New Mexico for many reasons, chief among them the close partnership we’ve developed with state and local leadership, who have made this project possible. Working alongside the Governor’s office, the Economic Development Department, the City of Albuquerque, key legislators from both parties, and the national labs, we’ve built true partnerships over the past several months. That collaboration gives us confidence that together we’ll be able to move quickly to deliver on the promise of low-cost fusion power.”

    Upon completion, the project will bring more than two hundred long-term jobs to the state, along with hundreds more construction jobs, workforce development programs, and regional economic activity. It will be an anchor investment for a broader fusion ecosystem in New Mexico.

    Rob Black is the New Mexico Economic Development Department Cabinet Secretary. He said, “This is a groundbreaking project that puts New Mexico at the forefront of fusion energy. Welcoming a world-class company like this into our state opens the door to an entirely new era of clean energy innovation. It means thousands of potential future jobs, a new supply chain, and the opportunity to cement our state’s leadership in clean technology for decades to come.”

  • Nuclear Fusion 145 – First Light Fusion Pioneering A New Inertial Fusion Technology

    First Light Fusion | LinkedIn

    First Light Fusion (FLF) is a British inertial fusion energy developer. It has just presented the first commercially viable, reactor-compatible path to ‘high gain’ fusion, which it says would drastically reduce the cost of what the company says is a virtually limitless clean energy source.

    In its white paper published today, FLF outlines a novel and scientifically grounded approach to fusion energy called Fusion via Low-power Assembly and Rapid Excitation (FLARE). The conventional inertial fusion energy (IFE) approach is to compress and heat the fuel at the same time to achieve ignition. FLARE splits this process into two stages. In the first stage, the fuel is compressed in a controlled and highly efficient manner. Then in the second stage, a separate process is used to ignite the compressed fuel, generating a massive surplus of energy, a concept known as ‘fast ignition’.

    FLARE leverages over fourteen years of First Light’s inertial fusion experience and its unique controlled-amplification technology. They have created a system capable of reaching the high gain levels needed for cost competitive energy production. Their new approach “would underpin the design for commercial reactors that can be based on much lower power systems that already exist today, opening up an opportunity for partners to build those systems, using FLF’s technology as the fuel, and to roll it out worldwide,” according to the company.

    Gain is the ratio of energy output to energy input in a fusion reaction. It is the critical metric determining commercial viability. The current record gain level is four, achieved at the U.S. Department of Energy’s National Ignition Facility (NIF) in May of this year.

    “The FLARE concept, as detailed in today’s white paper, could produce an energy gain of up to 1000. FLF’s economic modelling suggests that a gain of at least 200 is needed for fusion energy to be commercially competitive, while a gain of 1000 would enable very low-cost power,” according to the company said.

    According to FLF, an experimental gain scale facility is expected to cost one-twentieth of the NIF cost and could be built using existing technologies. Due to the lower energy and power requirements provided by the FLARE technology, future commercial fusion power plants would have significantly lower capital costs than other plausible IFE approaches. They would have lower complexity and core components such as the energy delivery system costing one-tenth of the capital cost of previous fast ignition schemes.

    “By building on existing technology, First Light’s approach takes the brakes off inertial fusion deployment as it has the potential to leverage existing supply chains, significantly reduce capital expenditure, speed up planning approvals and reduce regulatory hurdles in the deployment of commercial fusion plants,” FLF said.

    Mark Thomas is the CEO of FLF. He said, “This is a pivotal moment not just for First Light, but for the future of energy. With the FLARE approach, we’ve laid out the world’s first commercially viable, reactor-compatible pathway to high gain inertial fusion – and it’s grounded in real science, proven technologies, and practical engineering. A pathway to a gain of 1000 puts us well beyond the threshold where fusion becomes economically transformative. Through our approach, we’re opening the door to a new industrial sector – and we want to bring others with us.”

    FLF was founded by Yiannis Ventikos of the Mechanical Engineering Department at University College, London, and Nicholas Hawker, formerly an engineering lecturer at Lady Margaret Hall, Oxford. The company was spun out of the University of Oxford in July of 2011, with seed capital from IP Group plc, Parkwalk Advisors Ltd and private investors. Invesco and OSI supplied follow-on capital.

    In February of this year, Oxfordshire-based FLF announced it will focus on commercial partnerships with other fusion companies who want to use its amplifier technology, as well as with companies who have non-fusion applications such as NASA seeking to replicate potential high-velocity impacts in space. By dropping its plans for a commercial fusion power plant, and instead targeting commercial partnerships with others, FLF aims to “capitalize on the huge inertial fusion energy market opportunities enabling earlier revenues and lowering the long-term funding requirement.”
