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 1353 – U.S. Renews Interest In Recycling Spent Nuclear Fuel – Part 1 of 3 Parts.

    Part 1 of 3 Parts
         The nuclear waste sitting at power plants across the United States contains enough radioactive materials to power the country for more than one hundred years at the current rate of power consumption. Recycling spent nuclear fuel was banned in the U.S. in 1977. President Jimmy Carter was afraid that nuclear reprocessing could result in the production of weapons-grade nuclear materials which could be used to make nuclear weapons.
         In the past forty-seven years, China, France, Japan, Russia and the United Kingdom have all developed the technology necessary to recycle spent nuclear fuel into new fuel. The U.S. made a plan to bury spent nuclear fuel underground and even began construction of a facility. However, the project was abandoned without a clear alternative.
         The short-term spending bill passed this week in the U.S. House of Representatives to avert a government shutdown contains the first major government funding for commercializing technology to help recycle spent nuclear fuel.
         The new legislation dedicates ten million dollars to a cost-sharing program to help private nuclear startups pay for the expensive federal licensing process. For first time, nuclear waste-recycling companies are eligible for these government funds according to separate documents from Congress explaining what’s in the 1,050-page bill that passed Wednesday.
         Craig Piercy is the chief executive of the American Nuclear Society (ANS). The ANS is a professional organization that promotes nuclear science and technology. Piercy said, “There is developing commercial interest in nuclear-fuel recycling. What Congress is doing is providing some assistance to begin exploring the regulatory pathways to allow this to become a commercial reality.”
        Ten million dollars is a relatively small down payment to help launch an industry that may ultimately require billions to get off the ground. However, its inclusion in a spending bill with bipartisan support from both Republicans and Democrats represents a shift on what was once one of the most polarizing issues with respect to nuclear energy. The funding was a particular priority for Rep. Chuck Fleischmann (R-Tenn.) who is a supporter of nuclear energy. On the other side of the aisle, Rep. Alexandria Ocasio-Cortez (D-N.Y.), a left-wing stalwart, also recently came out in support of recycling spent nuclear fuel.
        Edward McGinnis spent 30 years working on nuclear power at the Energy Department before becoming the chief executive of the fuel-recycling startup Curio. He said, “This is a big deal. It’s the first time that we’re seeing recycling and reprocessing as a funding item. That says a lot. That is a reflection of how much the nuclear policy landscape in a bipartisan way has changed.”
         The California-based reactor startup Oklo Inc. is working on developing technology to commercialize spent nuclear fuel reprocessing with plans to ultimately recycle all its own fuel. Last month, Wisconsin-based SHINE Technologies signed an arrangement with French uranium mining and manufacturing giant Orano to produce new reactor fuel from recycled spent nuclear fuel.
         Reprocessing spent nuclear fuel involves extracting and handling the types of dangerous isotopes of radioactive elements, such as plutonium, that can be used in the construction of nuclear weapons.

  • Nuclear Reactors 1352 – IsoEnergy Is Working To Reopen The Tony M Uranium Mine In Utah

    Nuclear Reactors 1352 – IsoEnergy Is Working To Reopen The Tony M Uranium Mine In Utah

         IsoEnergy Ltd. is a leading, globally diversified uranium mining company with substantial current and historical mineral resources in top uranium mining jurisdictions of Canada, the U.S., Australia, and Argentina at varying stages of development. This provides near, medium, and long-term leverage to rising uranium prices. It is based in in Saskatoon, Canada. 
         IsoEnergy will reopen underground access at the Tony M uranium mine in Utah during the first half of this year. IsoEnergy’s goal is to restart uranium production operations in 2025 if market conditions continue as expected.
         This “strategic decision” is underpinned by rising uranium prices, the climate of increasing support and demand for nuclear energy, and the recent announcement by Energy Fuels Inc to restart its uranium circuit at the White Mesa mill, IsoEnergy said. Energy Fuels Inc has a toll milling agreement with IsoEnergy.
        The Tony M mine is one of three past-producing, fully-permitted, uranium mines in Utah owned by IsoEnergy. It produced nearly one million pounds of uranium oxide (U3O8) during two different periods of operation from 1979-1984 and from 2007-2008. The mine was acquired by IsoEnergy Ltd on the company’s share-for-share merger with Consolidated Uranium Inc, which was completed last December.
         IsoEnergy’s announcement comes just over six months after Consolidated Uranium began work towards reopening the underground workings at the Tony M mine. IsoEnergy said it plans to reopen the main decline into the mine and open underground access by the end of the first half of 2024.
         IsoEnergy said, “This critical step is expected to facilitate the assessment of the mine’s underground conditions, enable direct analysis of the uranium mineralization in place, and allow for the collection of necessary data required to prepare an efficient mine plan.” The company added, “The work program also includes underground and surface geological mapping of the sandstone-hosted uranium and vanadium mineralization to allow for more precise extraction plans for inclusion in an updated economic study.”
        Energy Fuels announced in late December of last year that it plans to restart the uranium circuit at the White Mesa mill in 2025. IsoEnergy said it intends to deliver uranium ore to the mill in time for the restart of the uranium circuit.
         IsoEnergy believes that the timing of the restart is “ideal”, given current and near-term uranium market dynamics according to CEO and Director Phil Williams said. He added that “With the uranium spot price now trading around USD100 per pound, we are in the very fortunate position of owning multiple, past-producing, fully-permitted uranium mines in the US that we believe can be restarted quickly with relatively low capital costs. Our existing toll-milling agreement with Energy Fuels places IsoEnergy in a unique position to become a conventional uranium producer in the near-term.”
         The work program at Tony M mine includes updating and maintaining the existing mine ventilation and other infrastructure, surveying and rehabilitating underground mine workings and ground support as needed and upgrading and/or replacement of utilities.
         IsoEnergy mentioned that it is also evaluating plans to restart operations at the Daneros and Rim mines.
