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 975 – Naarea Designing Molten Salt eXtra Small Modular Reactor

          New French micro-reactor developer Naarea is working on designs for an ultra-compact small modular reactor they call the eXtra Small Modular Reactor (XSMR). Dassault Systèmes is going to supply Naarea with a cloud-based platform on which to virtually design the 1-to-40-megawatt molten salt reactor. Naarea says that the first units of XSMR will be produced by 2030.
         Naarea has also signed a cooperative agreement with French engineering group Assystem. Under this agreement, Assystem will supply Naarea with “its historical experience in the nuclear sector as well as its expertise in digital engineering aimed at better controlling the complexity of projects through the management and use of industrial data.”
         Assystem will create a computer simulation of the XSMR in order to study the behavior of the design. This digital twin will allow rapid convergences towards the optimal design, provide critical elements for validating the design and enable the rapid launch of the construction of the physical prototype. Assystem will also draw on its knowledge of highly regulated environments to support Naarea for the development of this new technology in compliance within the established nuclear framework.
          Naarea was formally created on the 29th of November by co-founder Jean-Luc Alexandre and Ivan Gavriloff to develop and promote the XSMR design. Naarea says that it has already benefited from the support of private shareholders. This will be completed soon by a fundraiser which is being finalized.
         Naarea says that is ultra-compact molten sale reactor utilizes “the untapped potential of used radioactive materials, and thorium, unused mining waste. The current stocks of these two wastes will supply the energy needs of humanity for thousands of years and reconcile humanity with its future.”
         After the completion of the development of its XSMR, Naarea intends to target applications in areas such as transportation, agriculture and smart buildings. The company says that there is no need for the XSMR to be grid-connected because of its compact size. The XSMR can “be deployed as close as possible to regions, to match energy demand as closely as possible and allow the control of security of supply, at the service of industries and communities.”
         Alexandre said, “The agreement we are signing with Assystem today is the concrete realization of a collaboration that has been underway for several months and is already bearing fruit. It is a fundamental step in the progress of the Naarea project, alongside a reference player who supports and adheres to our desire to participate in the sustainable transformation of our societies by mobilizing consciences around this equitable ideal.”
         Alexandre went on to say, “The agreement we are signing with Assystem today is the concrete realization of a collaboration that has been underway for several months and is already bearing fruit. It is a fundamental step in the progress of the Naarea project, alongside a reference player who supports and adheres to our desire to participate in the sustainable transformation of our societies by mobilizing consciences around this equitable ideal.”
         Stéphane Aubarbier is the COO of Assystem said, “We are delighted to formalize our commitment to Naarea and to support this innovative and disruptive project. Assystem’s mission is to develop decarbonized sources of electricity production throughout the world to combat climate change. As such, advanced modular reactors represent an additional technology alongside high-power reactors, SMRs and renewable energies to accelerate the energy transition. We are proud to provide Naarea with our nuclear and digital expertise to support its growth.”
         Dassault Systèmes announced yesterday that Naarea will utilize its 3DEXPERIENCE platform on the cloud to virtually design the new Naarea reactor. Dassault Systèmes said, “In this unified virtual environment, Naarea can collaborate to design the reactor’s system, simulate its operation, and validate it with end-to-end traceability and design quality. As the platform is based on the cloud, Naarea could access the virtual twin from anywhere at any time and increase the number of users as needed.”

  • Nuclear Weapons 760 – Belarus Offers To Host Russian Nuclear Weapons If NATA Moves Nuclear Weapons Into Eastern Europe – Part 2 of 2 Parts

    Nuclear Weapons 760 – Belarus Offers To Host Russian Nuclear Weapons If NATA Moves Nuclear Weapons Into Eastern Europe – Part 2 of 2 Parts

    Part 2 of 2 Parts (Please read Part 1 first)
         Responding to the offer by President Lukashenko’s to host Russian nuclear weapons, NATO Secretary General Jens Stoltenberg said that the Western military alliance would need to consider redeploying nuclear weapons to Eastern Europe if the new German government makes changes to the country’s policy on sharing nuclear weapons among its members. Stoltenberg said, “Germany can, of course, decide whether there will be nuclear weapons in their country, but the alternative is that we easily end up with nuclear weapons in other countries in Europe, also to the east of Germany.”
         Alexei Arbatov is a Moscow-based foreign policy expert. He described the possible redeployment of U.S. nuclear weapons to Eastern Europe as a “mad, adventurist move.” If Russia responds to such a redeployment by sending its nuclear weapons to Belarus, “the situation would be more dangerous than it was during the Cold War.” His comments were reported by the Interfax news agency.
         Lukashenko has moved closer to Russia since he faced Western criticism and pressure over his election to a sixth term in an August 2020 election. Belarus opposition parties and Western nations rejected the election as rigged. Belarusian authorities responded to protests that were triggered by the election with a sweeping crackdown. This prompted the European Union and the United States to hit Belarus with several rounds of serious sanctions.
         Tensions in the region have escalated further since this summer because of the arrival of migrants and refugees on the Belarusian border with European Union member Poland.
          The European Union has accused Lukashenko of retaliating for the sanctions by using disparate asylum-seekers as pawns and tricking them into trying to enter Poland, Lithuania and Latvia with the goal of destabilizing the entire European Union. Some refugees have claimed that Belarus directed them to metal fences between Belarus and its neighbors and supplyied them with wire cutters to breach the fences.
          Belarusian authorities have denied the accusation and have accused the European Union of failing to offer safe passage to migrants and refugees. Since November 8th, a large group of people, mostly Iraqi Kurds, has been stranded at the Belarusian border crossing with Poland where forces from the two countries were facing off. Most of these people stuck in freezing temperatures are fleeing conflict or hopelessness at home. They aim to reach Germany or other Western European countries. Lukashenko has been attempting to turn the tables on the West and cast the tensions over migration as part of a purported plot against Belarus and Russia.
