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 1058 – Does India Need French Nuclear Reactors – Part 2 of 3 Parts

    Part 2 of 3 Parts (Please read Part 1 first)
         Following its submission of a new techno-commercial offer to India, EDF’s Ramany said that the company is moving ahead with the “the concretization of the largest nuclear power plant in the world [with the] fully proven EPR technology.”
         In spite of EDF’s hope that the reactors would shortly become operations, negotiations with NPCIL have stalled over the past decade for several reasons. These include increasing cost estimates, increasing doubts over their performance, disagreement of liability in the case of a reactor accident, and local protests. EPR projects under construction and in operation have encountered problems in different parts of the world.
         The first EPR project was named Olkiluoto-3. It started in Finland in 2003 and was connected to the Finnish grid in 2022. It was completed thirteen years behind schedule and has not yet begun operations. There are two EPRs under construction in the U.K. These are known as Hinkley Point C-1 and C-2. There is also a French EPR named Flamanville-3 under construction. The proposed two-unit EPR plant at Hinkley Point was originally scheduled to begin operations in 2025 but it has been delayed until June of 2027. It will cost three and a half billion dollars more than was originally proposed. The current estimation is that it will cost twenty-nine and half billion dollars. The Flamanville EPR is over a decade behind schedule. Its budget has expanded from three billion three hundred million dollars to twelve billion seven hundred million dollars.
         Suvrat Raju and MV Ramana are India physicists. The have questioned the safety and economics of the EPR reactors proposed for the Jaitapur site. In 2013, they estimated that the cost of electricity from the proposed reactors at Jaitapur would cost eighteen cents per kilowatt hour. Their calculations were based on the construction costs of the EPRs in Finland and France. Since then, the costs of EPR construction have increased while the cost of alternatives has declined sharply.
          In an interview, Ramana said, “The costs of the EPRs being built in Western Europe have gone up, while costs of renewable sources of energy, especially solar photovoltaics, have declined. In 2020, one solar project developer offered to sell electricity at the especially low rate of two and a half cents. It is routine to find projects proposed for around 3 cents per kWh.”
         It is significant that the total amount the India government will spend on this project has still not been made public. In 2019, the EDF announced that the cost is “confidential and may not be disclosed.” EDF has also refused to release an estimate of the cost per kilowatt hour.
         EPRs’ problems are not limited to massive cost overruns and significant delays. Raju and Ramana wrote in 2019 that “In addition to the high costs, safety problems with the reactor design and construction have emerged in several EPRs.” Serious problems occurred during the manufacture of the reactor pressure vessel of the EPR at Flamanville in France. The steel in parts of the vessel was found to have too much carbon. (Too much carbon concentration in the steel of the reactor vessel can lead to lower than expected mechanical properties. This could compromise its safety. The reactor vessel acts as a key barrier against radioactive materials escaping from the core.)

  • Nuclear Reactors 1057 – Does India Need French Nuclear Reactors – Part 1 of 3 Parts

    Part 1 of 3 Parts
         Vakisasai Ramany is a senior vice-president of Electricité de France (EDF), a major French electric utility company. In April of 2021, he traveled to India to deliver a technical and commercial offer for nuclear reactors in person. During his visit, Ramany met with officials of the Indian Department of Atomic Energy (DAE) and the Nuclear Power Corporation of India Limited (NPCIL). NPCIL is the state-owned company that operates most of India’s commercial nuclear power plants. He submitted a long-delayed techno-commercial offer to supply engineering studies and equipment for the construction of six European Pressurized Reactors (EPRs) at the Jaitapur site in Maharashtra, India. The project was claimed to be the ”most powerful in the world”. It consisted of a nuclear power plant with a total installed capacity of nine and a half gigawatts of electricity. EPRs have had a significantly troubling record of cost and time overruns. The proposed Jaitapur project has faced strong protests from local residents and environmental activists. The cost of these reactors is likely to be in the tens of billions of dollars. So, the stakes are high for the French nuclear company to conclude its deal with India.
         In 2008, France and India signed a bilateral agreement for civilian nuclear cooperation on the development of nuclear energy. India had been placed under U.S. sanctions for conducting nuclear weapons tests in 1974 and 1998. India could not conduct trade in nuclear technology with other countries under the sanctions. India signed an agreement with the U.S. that allowed India to trade in nuclear technology which was followed by the agreement between France and India.
         India’s first nuclear test in 1974 provided the impetus for the creation of the Nuclear Suppliers Group (NSG). The NSG is a trade consortium established by countries involved in exporting nuclear energy technologies. The group established requirements that nuclear technologies and materials should be exported only to countries that had signed the Nuclear Non-Proliferation Treaty (NPT). The NPT entered into force in 1970. By 1974, India was not a signatory of the NPT and has never joined the treaty. Because of this, it was not allowed to purchase nuclear reactors or uranium from any member of the NSG. In 2008, India’s Prime Minister and the U.S. president formed an agreement. The U.S. government used its political power to force many of the more reluctant members of the NSG to sign a special waiver for India. Many countries, especially France and Russia, supported the waiver. They were drawn by the opportunities represented by India’s rapidly expanding energy market.
         Following the creation of the India-France bilateral agreement, India’s NPCIL and the French nuclear-maker Areva signed an agreement in 2009 for the supply of two to six EPRs. Soon after Areva fell into major financial trouble, it was taken over by EDF in 2016.
         EPRs are a type of pressurized water reactor built by a French and German collaboration. The reactors are advertised to have better safety features than some earlier designs. These features include a double barrier to ensure containment of radioactive materials in case of accidents. They are also claimed to be able to resist extreme hazards like earthquakes, flooding and extreme temperatures.
