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.

  • Nuclear Reactors 1475 – Naarea Announces Collaboration With Phoenix Manufacture On The Design And Manufacture Of Its XAMR Molten Salt Microreactor

    Nuclear Reactors 1475 – Naarea Announces Collaboration With Phoenix Manufacture On The Design And Manufacture Of Its XAMR Molten Salt Microreactor

         French microreactor developer Naarea is going to collaborate with Phoenix Manufacture, a company which specializing in the industrialization of complex devices, to work towards the mass production of Naarea’s XAMR molten salt fast microreactor.
         The aim of this collaboration is to structure the industrialization of the XAMR, integrating the key phases of the project including design, prototyping, first-of-a-kind (FOAK) manufacturing and mass production. In order to meet these challenges, Naarea and Phoenix Manufacture will employ technologies such as 3D printing and design a joint plant including specially designed spent nuclear fuel reprocessing facilities.
         Phoenix Manufacture is based in Niort, western France. It specializes in industrial precision engineering and the design and manufacture of mechanical systems for the military, nuclear, petroleum, aerospace and robotics sectors.
         The partnership between Naarea and Phoenix Manufacture intends to implement industrial solutions for the phases of development of the XAMR. They will focus especially on prototyping, FOAK production and mass production.
         The collaboration is based on five phases extending to 2032. The first phase includes validation of raw materials and the manufacturability of parts designed by Naarea for additive manufacturing. The second phase consists of prototyping the components of the XAMR microreactor. The third phase is series production, including providing the necessary parts for the FOAK and mass production. The fourth phase involves scaling up production capacity, including studying the creation of a joint production facility for XAMR components, pooling of resources and mutual skill development. The fifth and final phase will be the evaluation of solutions for recycling and recovering waste material resulting from production and the recycling of used components.
         Jean-Luc Alexandre is the founder of Naarea and CEO. He said, “We have chosen to rely on the expertise and skill of Phoenix Manufacture, a French company that will contribute to the design of an XAMR microreactor made in France. Incorporating additive manufacturing represents a major asset for us: it will allow us to produce parts with consistent quality controlled in situ at each step of the manufacturing process. Additive manufacturing also makes it possible to lower production costs, reduce assembly needs and meet the highest standards in terms of safety and security, which remains our absolute priority.”
         Marco Calcamuggi is the co-founder of Phoenix Manufacture and CEO. He said, “We are proud of this strategic partnership with Naarea, since additive manufacturing is at the heart of our vision for French reindustrialization. We firmly believe that this disruptive technology is profoundly transforming all industries, in particular, the nuclear sector.”
         Naarea was formally established in November 2021. It says that its ultra-compact molten salt fast neutron reactor will use “the untapped potential of used radioactive materials, and thorium, unused mining waste”. Once it finishes the eXtra Advanced Nuclear Reactor (XAMR) design, the company intends to explore applications in areas such as transportation, agriculture and smart buildings.
        Naarea says that its reactor is compact in size and there is no need for it to be grid-connected. The XAMR can “be deployed as close as possible to regions, to match energy demand as closely as possible and allow the control of security of supply, at the service of industries and communities”. Each XAMR can generate forty megawatts.  Naarea expects its first XAMR to be produced by 2030.
         Earlier this month, Naarea announced a strategic partnership with advanced energy management platform QGEMS set to commence in 2025. The partnership is aimed at integrating QGEMS’ technology to optimize Naarea’s energy production and distribution. In addition, Naarea said that using QGEMS’ advanced energy management system could extend the applications of its reactor to data and AI centers, commercial properties, industrial facilities and remote territories.

  • Nuclear Reactors 1474 – EDF Is Managing The U.K. Fleet of Commercial Nuclear Power Reactors – Part 2 of 2 Parts

    Nuclear Reactors 1474 – EDF Is Managing The U.K. Fleet of Commercial Nuclear Power Reactors – Part 2 of 2 Parts

    Part 2 of 2 Parts (Please read Part 1 first)
         EDF said its goal is to help restore U.K. nuclear output back above sixty terawatts per annum by replacing the existing AGR fleet capacity through the installation of new EPRs at Hinkley Point C and Sizewell C and extending Sizewell B out to 2055.
         EDF added, “Beyond this major commitment, we will continue to support government and industry with any plans to deliver a fleet of small modular reactors (SMRs), further large-scale nuclear at Wylfa and elsewhere and investment in advanced technologies. In line with the U.K. government strategy, EDF has continued to explore options for the long-term future of our sites. We are open in terms of which designs are taken forward at our sites and look forward to the government’s revised nuclear roadmap and further direction on which technologies should be developed on which sites as part of a holistic UK new build program.”
         At the same time as EDF Energy released its annual nuclear fleet update, a new report was published by independent consultants Economic Insight highlighting the significant contribution that nuclear energy has made to economic growth in the U.K. over the last fifty years.
         The new report was commissioned by EDF. It shows that the current fleet of eight nuclear power plants have so far contributed more than one hundred fifty-three billion dollars to the U.K. economy since the two oldest plants started operating in 1976.
         The report said that the fleet supported thirty thousand jobs each year when all eight plants were generating. Five thousand of those jobs have been directly with EDF. The majority of the jobs came through supply chain and other induced impacts, like hospitality businesses supported by local wages. That means that there was an average of five point three additional jobs in the U.K. economy for every EDF job.
        The positive impact on the U.K. supply chain is also highlighted with a finding that more than ninety percent of supply chain spending is made domestically, with around fifteen hundred U.K.-based companies.
         The report also employed a new methodology for calculating the carbon the nuclear plants have prevented from entering the atmosphere. Instead of comparing the nuclear output with gas generation alone, the report examines the historical energy mix, when coal was the prevailing fuel. This reveals that the two thousand one hundred and twenty-six terawatts of electricity the nuclear fleet has generated has prevented the emission of one billion tons of carbon, the equivalent to sixty years of U.K. car emissions.
         Mark Hartley is the Managing Director of EDF’s Nuclear Operations business. He said, “Nuclear power stations do not just produce zero-carbon electricity, they have supported tens of thousands of livelihoods for decades. This is the first time the economic impact of the operating phase of the fleet has been analyzed in this way. Seeing how the combined value of the power, jobs and supply chain spend adds up over time really helps to throw into sharp relief the positive impact that these facilities have on economic growth. The investment made in these stations over nearly fifty years has paid dividends, and will continue to do so, not just for the people working and living close to the stations but also the millions who benefit from the zero-carbon electricity they produce.”
