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.

         While some observers claim that Yoon’s comments in the newspaper interview didn’t reveal much about new developments on the issue, Moon said that Yoon might have attempted to emphasize efforts to boost the effectiveness of the U.S. extended deterrence because N.K. is escalating its nuclear threats against S.K. In the interview, Yoon said that he finds it difficult to assure his people of a security guarantee with the apparent levels of U.S. security commitment.
         Park Won Gon is a professor at Ewha Womans University. He said, “This is an unnecessary dispute. Neither side was talking inaccurately. The extended deterrence is a commitment and a promise but not a treaty or a binding one. For S.K., they trust the U.S. but think there should be ways to institutionalize it because North Korea’s nuclear threats are rising. To do so, (the joint) planning and execution are the key.”
         S.K. has no nuclear weapons and is under the protection of a U.S. “nuclear umbrella.” This guarantees a devastating U.S. response in the event of an attack on S.K. However, some experts question the effectiveness of such a security commitment. They say that the decision to use U.S. nuclear weapons lies entirely with the U.S. president.
         Last year, N.K. test-launched over seventy ballistic and other missiles capable of reaching S.K., Japan, and even the U.S. mainline. Last September, N.K. also adopted a new law that authorized the preemptive use of nuclear weapons in a broad ranges of cases, including non-war scenarios.
         During a recent ruling party meeting, N.K. leader Kim Jong Un ordered the “exponential” expansion of his country’s nuclear arsenal. The new law also provides for the mass-production of tactical nuclear weapons for use in an attack on S.K. Kim also mentioned the development of a new ICBM capable of a “quick nuclear counter strike”.
         Last Wednesday, Yoon ordered S.K. officials to consider cancelling a tension-reduction deal with N.K. if the North launches provocations that violate S.K.’s territory. A report on Yoon’s orders said that he issued the instructions during a meeting to discuss N.K.’s recent flying of drones that Yoon says crossed the DMZ for the first time in five years.
         Yoon’s office did not provide many details about his government’s discussions with the U.S. Some observers say that S.K. is trying to obtain a greater role in the U.S. decision-making process on the deployment of its nuclear assets in times of tension with N.K.
          Kim Taewoo is the former head of S.K.’s Korea Institute for National Unification. He said that the reported S.K-U.S. discussion probably “benchmarked a NATO-style nuclear-sharing arrangement” that allows NATO member states’ warplanes to carry U.S nuclear weapons. He also remarked that the discussion still appears to be falling short of the NATO arrangement because possible nuclear exercises between the two countries would probably be S.K. Air Force aircraft escorting U.S. aircraft simulating nuclear strikes on N.K. during joint drills. Taewoo said, “North Korea would take this sensitively. (South Korea and the U.S.) are discussing this to get North Korea to take this sensitively … because that can be a deterrence against North Korea.”

    Nulcear Weapons 805 – Debate Over U.S. Commitment To South Korean Security – Part 1 of 2 Parts

    Part 1 of 2 Parts
         Talks with the U.S. on management of U.S. nuclear weapons on the Korean Peninsula are proceeding between South Korean (S.K.) officials and U.S. officials. U.S. President Biden denied that the two countries were discussing joint nuclear exercises while S.K. maintained that they were discussing involvement with U.S. nuclear weapons management because of increasing threats from North Korea (N.K.).
         The alleged difference between S.K. and the U.S. arose as S.K. is seeking a greater U.S. security commitment after North Korea’s record number of recent missile tests. The revision of the nuclear doctrine of N.K. last year is causing great concern among many South Koreans.
         Some analysts say that S.K.’s statement on the discussion is probably based on an agreement between their defense officials in November to conduct table-top exercises, usually computer simulations, annually. In addition, there were discussions of further strengthening the alliance’s information sharing, joint planning and execution. Last November, the alliance also reaffirmed the U.S. commitment to provide extended deterrence. This was a reference to a U.S. promise to use full U.S. capabilities, including nuclear weapons, to protect its allies.
         In a recent interview published last Monday, S.K. President Yoon Suk Yeol said that S.K. and the U.S. were pushing for joint planning and training involving U.S. nuclear assets. He said that the U.S. responded positively to the idea. Asked by a reporter after the interview was published about whether the U.S. and S.K. were discussing joint nuclear exercise, President Biden said “No.”
          After Biden’s comments created a brief stir in S.K., Yoon’s top adviser for press affairs, Kim Eun-hye, issued a statement Tuesday to reconfirm the earlier remarks by Yoon. Kim said that the two countries “are discussing an intel-sharing, a joint planning and subsequent joint execution plans over the management of U.S. nuclear assets in response to North Korea’s nuclear (threats).”
          The U.S. National Security Council issued a statement last Tuesday that stated that Biden and Yoon “tasked their teams to plan for an effective coordinated response to a range of scenarios, including nuclear use by North Korea.”
          A senior Biden administration official said U.S. and S.K. are expected to hold table-top exercises soon to lay out a potential joint response to a ranges of scenarios. These scenarios include deployment of a nuclear weapon by N.K. The official quoted requested anonymity when discussing such planning.
          Moon Seong Mook is an analyst for the Seoul-based Korea Research Institute for National Strategy. He said that Yoon was probably referring to the November agreement on the alliance’s capabilities. He added that these definitely include U.S. nuclear assets that are essential to the U.S. extended deterrence commitment.
         Moon, a retired brigadier general, went on to say, “South Korea isn’t a nuclear state, so it won’t be likely South Korea jointly using U.S. nuclear weapons. But the wording (in the November agreement) meant that South and the U.S. would consult on the operations of U.S. nukes from the planning stage until the training stage.”

         Many E.U. members are concerned about Hungary’s nuclear project because of Russia’s involvement. Other E.U. countries are against bringing any new nuclear projects online. Slovakia has announced plans to shift its nuclear commitment in its plans for the Mochovce power plant. It was constructed by the Soviet Union in the 1980s. A new nuclear reactor is currently being prepared to go operational in 2023. It will generate four hundred and seventy-one megawatts of power. If all goes according to plan, it will provide thirteen percent of Slovakia’s electricity needs which will make the country self-sufficient. However, neighboring Austria is staunchly opposed to the development due to the high costs involved in terms of both money and radioactive waste. Austria is also worried that Slovakia will be reliant on Russia for uranium fuel. About one fifth of E.U.’s uranium comes from Russia. Public opinion on nuclear power is seriously divided with sixty percent of Slovakians believing that nuclear power is safe. Seventy percent of Austrians do not agree.
         Currently, thirteen of the E.U.’s twenty-seven members generate electricity with nuclear power. Several others are not ready to accept nuclear power into the energy mix in spite of the current energy crisis. Germany has delayed the phaseout of its nuclear power plants. Other E.U. members are bringing new nuclear reactors online. Some analysts and critics do not believe that we are witnessing a nuclear renaissance. In spite on the Russia-Ukraine war creating a regional energy crisis, European governments have generally taken little action to shift their existing policies on nuclear plans. This suggests that a move to nuclear power may be exaggerated.
         Nicolas Berghmans is an energy and climate expert at the France-based Institute for Sustainable Development and International Relations (IDDRI). He explained that “We’re not talking about a nuclear renaissance, as such… but maybe more of a change of tide. A real nuclear renaissance would be if Europe decides to invest in more nuclear power plants.”
         Mark Hibbs is with the Carnegie Endowment for International Peace (CEIP). He suggested, “I don’t see a major watershed from what’s happening in Ukraine… Instead, the situation has reinforced some trends among countries already bought into nuclear energy, while slowing some opponents’ phase-outs of the technology.”
         While some may believe that there is a renaissance of nuclear energy, others disagree. The recent energy crisis has attracted greater attention to nuclear power. Some major powers are accelerating existing plans for nuclear plants. Others are showing an openness to diversifying their energy mix further through nuclear projects.
