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 1336 – Kazakprom Riding Rising Tide Of Uranium Prices

         Kazatomprom is the biggest uranium miner in the world. It has warned that it is likely to fall short of its production targets over the next two years. This announcement added another risk to uranium supply as demand for the nuclear fuel rebounds.
         The uranium miner is a London-listed company. It is controlled by Kazakhstan’s government via its sovereign wealth fund. The company said on Friday that shortages of sulfuric acid and construction delays at newly developed deposits are creating production challenges that could persist into 2025. Kazakhstan will outline the likely impact on output in a trading update by Feb. 1, it said.
         This setback adds to a list of supply challenges that have helped to catapult spot uranium prices to 15-year highs. Last year, the coup in Niger disrupting shipments to European reactors. Key miner Canada’s Cameco Corporation lowered its production targets due to challenges at its operations in Canada. Many of Cameco’s mines were mothballed as prices plunged in the wake of the Fukushima disaster. Now operators are racing to bring the shuttered Cameco mines back online as uranium demand rebounds.
         The global decarbonization drive and the disruption in energy markets in the wake of Russia’s invasion of Ukraine have helped spark a renaissance in the nuclear industry. National governments are increasingly willing to sign off on new nuclear projects despite cost over-runs and delays that continue to plague the nuclear sector.
         Shares in uranium miners jumped across the globe this week after the U.S. said it is soliciting bids to boost domestic production of a nuclear fuel known as high-assay low-enriched uranium (HALEU). The U.S. said that this was an effort to bolster national energy security. The U.K. also said this week that it will build another large-scale nuclear power plant as the nation maps out its biggest expansion of atomic energy in 70 years. This is beyond current projects by Electricite de France SA. The U.K. also intends to invest up to US$383 million dollars to boost production of HALEU. This nuclear fuel is currently only commercially produced in Russia.
         The war in Ukraine has triggered efforts to ease reliance on Russia’s nuclear enrichment facilities. These facilities are fed by Kazakhstan’s mines. The growing interdependence between the two countries has caused turmoil at Kazatomprom. The sale of a stake in a massive new mine to Russia in 2022 prompted an exodus of the senior managers.
         The deal for part of the Budenovskoye mine which is projected to become the world’s biggest source of the radioactive metal, will add to Russia’s nuclear power monopoly, Rosatom. It went through at the end of 2022, people familiar with the matter told Bloomberg last year. The deal was pushed by Kazakhstan’s sovereign wealth fund. It has been reported that action was against the wishes of the leadership at Kazatomprom.
         Kazatomprom said on Friday that it’s committed to fulfilling its contractual obligations to existing customers throughout 2024. The uranium miner’s production plans for 2025 are subject to “considerable supply chain risks,” it added.

  • Nuclear Weapons 841 – Dmitry Medvedev Threatens Use Of Nuclear Weapons in Ukraine

    Nuclear Weapons 841 – Dmitry Medvedev Threatens Use Of Nuclear Weapons in Ukraine

         Russia has not been shy about threatening the use of nuclear weapons against perceived enemies. They have a long history of flying nuclear bombers through foreign airspace without warning. They regularly sail nuclear capable warships and submarines through other countries territorial waters without notice. Putin is fond of bragging about horrendous new nuclear weapons such as a stealth undersea nuclear-armed drone that could sail right into any harbor in the world undetected. They have talked about and tested a nuclear-powered cruise missile that could fly for years without refueling.
         Russia’s nuclear policy states that if they are fighting a ground war against NATO and are being defeated on the battlefield with conventional weapons, they would consider the first use of tactical nuclear weapons on the battlefield.
          Recently, Putin bragged about sending tactical nuclear weapons to Belarus for possible use against Ukraine.  A senior ally of President Vladimir Putin warned on Thursday that any Ukrainian attacks on missile launch sites inside Russia with arms supplied by the United States and its allies would risk a nuclear response from Moscow.
         Former Russian President Dmitry Medvedev cast himself as a liberal modernizer when he was president from 2008-2012, but now presents himself as one of the fiercest anti-Western Kremlin hawks. Medvedev is currently deputy chairman of Russia’s Security Council. He recently said that some Ukrainian military commanders were considering hitting missile launch sites inside Russia with Western-supplied long-range missiles. He did not give more details of the alleged plans and there was no immediate reaction from Ukraine.
         He said, “What does this mean? It means only one thing – they risk running into the action of paragraph 19 of the fundamentals of Russia’s state policy in the field of nuclear deterrence. This should be remembered.”
         Paragraph nineteen of Russia’s 2020 nuclear doctrine sets out the conditions under which a Russian president would consider using a nuclear weapon. They could be used as a response to an attack using nuclear or other weapons of mass destruction, or to the use of conventional weapons against Russia “when the very existence of the state is put under threat.” Medvedev specifically mentioned point “g” of paragraph nineteen which deals with the nuclear response to a conventional weapons attack.
         Putin is the decision-maker when it comes to Russia’s vast nuclear arsenal. However, diplomats say Medvedev’s views give an indication of hawkish thinking at the top of the Kremlin which has cast the war as an existential struggle with the West.
         Kremlin critics have often dismissed some of Medvedev’s nuclear threats in the past as attempts to grab attention or to dissuade the West from supplying Ukraine with more weapons. The United States and its allies have recently approved nearly $250 billion in military and other support for Ukraine.
         The risk of nuclear escalation has hung over the Ukraine war since Russia invaded its neighbor in February 2022. The U.S. feared a Russian nuclear escalation in late 2022. Jake Sullivan is the White House national security adviser. He communicated to Russia concerns about any steps towards the use of a nuclear device in Ukraine.
         Russia and the United States are by far the world’s biggest nuclear powers. Russia controls about five thousand eight hundred and ninety nuclear warheads while the U.S. controls about five thousand two hundred and forty nuclear warheads, according to the Federation of American Scientists.

  • Radioactive Waste 924 – Holtec International Discusses Missing Equipment At Pilgrim Nuclear Power Plant

    Radioactive Waste 924 – Holtec International Discusses Missing Equipment At Pilgrim Nuclear Power Plant

         Several pieces of equipment containing radioactive material are missing at the Pilgrim Nuclear Power Station in Massachusetts. At the time of a periodic inventory last fall, items such as explosives detectors were not in their expected locations according to Pilgrim owner Holtec International.
         David Noyes is a compliance manager at Holtec. He described some of the missing items during a November meeting of the state’s Nuclear Decommissioning Citizens’ Advisory Panel. He said, “Three of the sources are Nickel-63 sources. They’re in explosive detectors, similar to what you’d see in any government installation, or any place where access is being controlled and material needs to … go through an explosive detector.”
         A Holtec report to the U.S. Nuclear Regulatory Commission states that seven sealed pieces of equipment containing low levels of radioactivity were initially identified as missing. Some were exempt from requirements for reporting. One was later found at the plant. Last fall, Holtec disclosed the discovery of missing items which happened in September. Noyes informed the panel what Holtec believes happened to five of the sources of radioactivity.
         Noyes said that “These five sources are assumed to have been disposed of as radioactive waste” during the cleanout of a building.
         The missing items are now getting fresh attention because local activist group Cape Downwinders said it has received an anonymous letter of complaint. Diane Turco is the director of Cape Downwinders. “This is a serious situation if there’s missing radioactive materials out. And it looks like Holtec hasn’t been paying attention to where this has gone.”
         Turco characterized the writer of the anonymous letter as a “whistleblower.” However, Holtec spokesman Patrick O’Brien questioned the idea that someone who works at Holtec is behind the recent letter and a previous letter last summer.
         The previous letter mentioned an increase in the evaporation of radioactive water from the plant, caused by the installation of submerged heaters. O’Brien said that in both cases, someone who repeats publicly available information has been portrayed as whistleblowing.
         In an email, O’Brien said the letters are utilizing public information “to create claims that are at the best skewed and the worst outright wrong/false to create a panic and/or headlines that with little effort could be answered in an educated manner.” The whistleblower letter claimed that four missing sources of radioactivity pose potential health and safety risks.
    Holtec described the missing items in a report to the NRC as “less than IAEA Category 3,” referring to definitions set by the International Atomic Energy Agency.  According to the IAEA, the next-lowest category, Category 4, can be described this way: “It is very unlikely that anyone would be permanently injured by this source. However, this amount of unshielded radioactive material, if not safely managed or securely protected, could possibly — although it would be unlikely — temporarily injure someone who handled it or who was otherwise in contact with it for many hours, or who was close to it for a period of many weeks. This amount of radioactive material, if dispersed, could not permanently injure persons.”
