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 1221 – Turkey Moves Ahead With Its Nuclear Power Program – Part 1 of 2 Parts

    Part 1 of 2 Parts
         Alikaan Çiftçi is the President of the Nuclear Industry Association of Turkey (NIATR). He recently explained that Turkey aspires to be a major regional manufacturing, trade and logistics hub to take advantage of the opportunities for nuclear energy in the Middle East, Africa and Turkey.
         It is expected that nuclear electricity generation capacity in Turkey, the Middle East and Africa will increase rapidly in the next two decades thanks to the completion of existing projects and projected construction agreements between countries in the region and nuclear vendors.
         Currently, fossil fuels account for more than ninety five percent of electricity production for all these countries’ energy needs. The growth in nuclear power capacity in the region will reduce dependence on these energy sources. It will also ensure energy security and meet increasing energy demand from population and economic growth.
         Nuclear energy provides cleaner, stable, reliable and cost-effective electricity. As a low-carbon baseload energy source, nuclear energy plays an important role in the decarbonization of the economy. Achieving supply stability in Turkey is critical where energy security is a vital issue for its strategic position in the region.
         Turkey has a National Energy Plan. The Plan calls for electricity to be produced by nuclear power plants in Turkey to reach eleven percent of the total energy production by 2030. The Turkish government claims that their energy portfolio will include conventional nuclear power plants under construction and planned. Small modular reactors will also be included.
         The Akkuyu nuclear power plant (NPP) on the Mediterranean coast of Turkey will be their first nuclear power plant. It is expected to have an installed capacity of four thousand eight hundred gigawatts. The first of the four planned units now has nuclear fuel on site. This coincides with the one hundredth anniversary of the Republic. Akkuyu NPP will employ about four thousand people during its operational phase. The estimated contribution of the NPP to Turkey’s gross domestic product over its entire life-cycle will be about fifty billion dollars. The NPP is being constructed by Rosatom, the Russian state atomic energy corporation.
         There were two devastating earthquakes last February in Turkey’s southern province, where the Akkuyu NPP is located. However, no damage was reported to the Akkuyu NPP being constructed in Mersin, Gulnar district. According to statements from Akkuyu spokespersons, the experts did not detect any damage to the buildings, equipment and cranes. Construction and assembly work at the NPP continue.
         The economic vitality created by the Akkuyu NPP is attraction attention. The project has become one of the biggest employment centers in the region during the construction process. It has set an example of successful localization with its supply changing of more than four hundred Turkish companies.
         Turkish manufacturers are providing a wide range of equipment from valves to pipes, storage tanks, reinforcing steel and various construction materials. Cables, heat and water insulation materials, cable trays, building materials, fire-resistant products, paints and coatings, brick products, and stainless steel materials are also being supplied by Turkish manufacturers. Turkish companies are gaining great experience in how and which materials should be manufactured in the nuclear field. The Akkuyu NPP not only contributes to employment but also creates “know-how” in the Turkish nuclear sector.

  • Nuclear Fusion 117 – Microsoft Signs Deal To Purchase Fusion Generated Electricity From Helion Energy

    Nuclear Fusion 117 – Microsoft Signs Deal To Purchase Fusion Generated Electricity From Helion Energy

         Nuclear fusion has been researched for decades. Many failed predictions thru the years have suggested that commercial nuclear fusion was only twenty years away. Huge technical challenges have prevented the dream from coming true but in the last few years, billions of dollars have been invested in a dozen companies working furiously on practical nuclear fusion around the globe.
         Microsoft and Helion Energy of Redmond, Washington announced last Wednesday that they had reached an historic agreement that could pave the way for the world’s first commercial nuclear fusion power plant. Helion is working on building the commercial facility in Washington state. The goal is to put the plant into operation by 2028 which is just five years away.
         Nuclear fusion could provide a potentially limitless source of carbon-free power. There are demonstration fusion reactors running or being constructed around the globe. However, none of them, including Helion’s reactors, have been able to produce more energy than they require to operate, let alone produce enough energy to feed into the electrical grid. Some analysts in the energy industry are skeptical that commercial fusion will ever be possible.
         If Helion’s fusion reactor design is successful, even though serious technical hurdles remain, it would have massive benefits in the long term as clean energy’s “Holy Grail” is finally achieved.
         David Kirtley is the co-founder and CEO of Helion. He said, “This is bigger than just Helion. This shows more broadly that fusion is transitioning from science experiments and science projects demonstrating key physics to now building products and building commercial power plants.”
         Helion and Microsoft have signed a power purchase agreement in which Microsoft agrees to purchase electricity from the fusion startup once the facility is generating significant amounts of electricity. Microsoft needs clean electricity to fuel the operations of its more than two hundred energy-hungry data centers around the world. Up to this point, Microsoft has relied primarily on wind and solar power. These sources have serious limitations because the wind does not always blow, and the sun does not always shine.
         Brad Smith is vice chair and president of Microsoft. He issued a statement which read, “Helion’s announcement supports our own long term clean energy goals and will advance the market to establish a new, efficient method for bringing more clean energy to the grid, faster.”
         The fusion energy market includes companies across the globe. Helion, Zap Energy, Avalanche and General Fusion are all headquartered in the Pacific Northwest. All of these companies have raised significant amounts of money from notable venture capitalists. Helion’s investors include OpenAI CEO Sam Altman and Facebook co-founder Dustin Moskovitz. Other startups have support from Bill Gates and Jeff Bezos.
         Scott Hsu is the U.S. Department of Energy senior advisor and lead fusion coordinator. He cheered the technology’s potential for lowering costs and providing secure energy globally. International experts warn that humanity needs to slash carbon pollution in the next quarter-century to avoid the worst climate change scenarios.
         Hsu said, “Fusion energy has incredible potential to empower people all over the world,” Hsu said by email. “If commercial fusion energy becomes available by the end of this decade, it could ease all the various possible pathways to [carbon] net-zero by 2050.”
