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 1391 – Industria Working On New Reactors For Poland

         Industria is a Polish industrial group. Their plan to construct a power plant based on Rolls-Royce’s small modular reactor (SMR) has been approved by the Polish Ministry of Climate and Environment.
         Industria sent its application for a decision-in-principle in December last year to Polish Climate and Environment Minister Paulina Hennig-Kloska. The application deals with the construction of a nuclear power plant using a four hundred and seventy megawatt Rolls-Royce SMR and a used nuclear fuel storage facility as an integral part of the power plant.
         On the 10th of May, Hennig-Kloska issued the ministry’s decision-in-principle. She said that she believes the investment would be in the public interest and in line with Poland’s energy and climate policies. The application was positively reviewed by the Head of the Internal Security Agency and the Minister of State Assets.
         The decision-in-principle represents official state approval for the planned investment. It is in accordance with the assumptions and concept presented by the company. It is the first decision in the process of issuing administrative permits for investments in nuclear power facilities in Poland that an investor may apply for. Obtaining such a permit entitles Industria to apply for a number of further administrative arrangements, such as a siting decision or construction license.

         Alan Woods is the Rolls-Royce SMR’s Director of Strategy and Business Development. He said, “Today’s decision-in-principle by Poland’s Environment Minister is extremely positive news and allows us to advance our commercial and technical discussions on the deployment of Rolls-Royce SMR power plants in Poland. Poland is one of a number of key export opportunities for Rolls-Royce SMR as we look to build on our progress in the UK and exploit the important competitive advantage our SMR design has over its competitors.”
         State-owned Industria is part of the Industrial Development Agency JSC (IDA. Last year, they selected Rolls-Royce SMR technology to fulfil the zero-emission energy goals of the Central Hydrogen Cluster in Poland and as part of their plans to produce fifty thousand tons of low-carbon hydrogen every year.
         In July of 2023, Industria signed a letter of intent with the Kostrzyn-Słubicka Special Economic Zone SA (KSSSE) with respect to cooperation on the location of a modular power plant based on Rolls-Royce SMR technology in the areas covered by the KSSSE.
         Poland’s Ministry of Climate and Environment issued a decision-in-principle in July of 2023 on copper and silver producer KGHM Polska Miedź SA’s plan to construct a NuScale VOYGR SMR nuclear power plant with a capacity of four hundred and sixty-two megawatts consisting of six modules, each with a capacity of seventy-seven megawatts.
         In December of 2023, the ministry issued decisions-in-principle to Orlen Synthos Green Energy for the construction of nuclear power plants based on GE Hitachi Nuclear Energy’s BWRX-300 SMR at six locations. A total of twenty-four BWRX-300 reactors are planned at the sites.
         The ministry has also issued decisions-in-principle for the construction of two large nuclear power plants. The first is a three thousand- and fifty-megawatt plant in Pomerania using Westinghouse’s AP1000 technology. The second is for a plant comprising two South Korean-supplied APR1400 reactors in the Patnów-Konin region.

  • Energoatom and Hyundai E&C have just signed a Memorandum of Cooperation To Collaborate On New Nuclear Reactors For Ukraine

    Energoatom and Hyundai E&C have just signed a Memorandum of Cooperation To Collaborate On New Nuclear Reactors For Ukraine

         Energoatom and Hyundai E&C have just signed a memorandum of cooperation (MoC). The MoC signed by the Ukranian and South Korean companies covers collaboration on the design, construction and commissioning of new nuclear units in Ukraine.
         The MoC was signed by Energoatom’s Petro Kotin and Korean Hyundai Engineering and Construction Executive Vice President and Operations Director Choi Young in the presence of Ukraine’s Energy Minister Herman Halushchenko and South Korea’s Ambassador to Ukraine Kim Hyun-Tae.
         Halushchenko said the MoC was important in terms of the plans for new Westinghouse AP1000 units at the Khmelnitsky nuclear power plant. He continued, “It is important that, together with the Korean side, we sign this memorandum during the war and, without waiting for its end, move forward. I am confident that together we will build an energy industry in Ukraine that will meet the best global standards.”
         Hyun-Tae said the MoC would “contribute to the development of Ukrainian-Korean cooperation in the nuclear industry, in particular, the exchange of experience in the field of nuclear technologies”.

         Kotin said, “South Korea has developed nuclear energy and expertise in the nuclear industry. Energoatom and Ukraine as a whole are interested in the development of our cooperation with the Hyundai company, which is one of the world leaders in this market.”
    The MoC expands on a letter of intent that was signed by the two companies in November 2023. In May 2022 Westinghouse and Hyundai E&C signed a strategic cooperation agreement to jointly participate in global AP1000 plant opportunities. Last month a ceremony was held to mark the start of the project to construct what will become unit 5 at Khmelnitsky NPP.
         Ukraine has fifteen nuclear units which could generate about half of its electricity. These units including the six at the Zaporizhzhia nuclear power plant which has been under Russian military control since early March 2022. Ukraine’s plan to expand nuclear power include proposals for nine new AP1000 reactors across the country.
         Khmelnitsky’s first reactor was connected to the grid in 1987. However, work on three other reactors was halted in 1990, at a time when unit 3 was seventy five percent complete. Work on the second reactor was restarted and it was eventually connected to the grid in 2004. A project to complete units 3 and 4 is currently under way. Last month, the Ukrainian Cabinet brought forward a draft law on their construction/completion. Halushchenko said earlier this year that unit 3 could be put into operation in as little as two and a half years.
         Two of the new AP1000s are due to become the fifth and six units at Khmelnitsky. This will bring the plant’s total capacity beyond that of the six-unit Zaporizhzhia plant which has been under Russian military control since early March 2022. During their talks, Energoatom and Hyundai E&C considered all these projects. They also discussed agreements with Holtec International on the construction of factories for the production of equipment for small modular reactors (SMR) and containers for used nuclear fuel.

  • Nuclear Reactors 1389 – Canadian Nuclear Laboratories, Atomic Energy of Canada Limited and AtkinsRéalis Are Collaborating On The Construction Of A Heavy Water Plant.

    Nuclear Reactors 1389 – Canadian Nuclear Laboratories, Atomic Energy of Canada Limited and AtkinsRéalis Are Collaborating On The Construction Of A Heavy Water Plant.

         Canadian Nuclear Laboratories, Atomic Energy of Canada Limited and AtkinsRéalis have signed a memorandum of understanding (MoU) to investigate opportunities to collaborate on the production of heavy water for use in new Candu reactors in Canada.
          Heavy water is a form of water in which the normal hydrogen is replaced by a heavier isotope of hydrogen called deuterium. It is used as both the moderator and as the reactor coolant in pressurized heavy water reactors, such as Candus. It has not been produced in Canada for more than 25 years.
         The MoU brings together AtkinsRéalis’ nuclear and industrial capabilities in Canada as the licensee of Candu technology, with Atomic Energy of Canada Limited (AECL), owner of Candu intellectual property and other heavy water production technologies, and the Canadian Nuclear Laboratories (CNL) who is a world leader in the industry with extensive experience in heavy water technologies.
         The objective of the MoU is to examine options and chose cost efficient, environmentally responsible, and viable heavy water production technologies, which could include the creation of industrial scale heavy water production facilities to support the deployment of a new fleet of Candu reactors.
         Ian Edwards is the AtkinsRéalis President and CEO. He said that “This collaboration among important stakeholders in the Canadian nuclear sector sets the stage for Canada to lead the global heavy water market, solidifying its role as a key player in the energy transition. With Candu reactors operating across four continents, a global nuclear new build market with expected demand in excess of 1000 new reactors, a strong Candu reactor refurbishment market, and the introduction of the new Candu Monark 1000 MW reactor in addition to the existing Enhanced Candu 6, this memorandum of understanding could not have come at a better time.”
         Fred Dermarkar is the AECL President and CEO. He added that “I am pleased that AECL, CNL and AtkinsRéalis are collaborating and working together to advance heavy water production for Candu reactor technology. Candu technology is uniquely positioned to contribute to important national objectives such as decarbonization, energy security, economic growth and maintaining Canada’s Tier-1 nuclear nation status.”
         Jack Craig is the CNL President and CEO. He said, “The deployment of large-scale nuclear power in Canada is an enormous undertaking, and will require extensive alignment and coordination between organizations, industries, public officials and regulators from across the country. Heavy water is one key piece of the larger puzzle, and CNL is working hard to play a leadership role in this process, ensuring that the broader industry is working towards a shared vision, and that the necessary inventory and production capabilities are in place to supply these reactors.”
         The Bruce Heavy Water Plant, which operated from 1973 until 1998, was built by AECL. It was located within the boundaries of the Bruce nuclear power plant, but was owned and operated by Ontario Power Generation. The plant was constructed to supply the heavy water needed for Canada’s nuclear power program. Candus are very efficient in their use of heavy water, which is recycled. This means that the Bruce Heavy Water Plant’s output was no longer needed after sufficient stockpiles were produced. Decommissioning of the Bruce Heavy Water Plant’s began in 2004, with demolition work completed in 2006.
