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 1294 – Ontario Power Generation Is Working On Construction Of Four Small Modular Reactors At Its Darlington Site

    Nuclear Reactors 1294 – Ontario Power Generation Is Working On Construction Of Four Small Modular Reactors At Its Darlington Site

         Ontario Power Generation (OPG) will construct and operate four small modular reactors (SMRs) at its Darlington site. It is estimated that these SMRs will contribute about eleven billion dollars to Canada’s GDP. This will include about one billion dollars to Ontario’s GDP. The SMRs will create and sustain two thousand jobs every year in Canada over the next sixty-five years. This information was reported by the Conference Board of Canada (CBC).
         The SMR report said, “There is now an increasing need for investing in stable and reliable energy resources, such as commercial-scale SMR technology. The deployment of more nuclear power in Ontario is a major investment decision. It is therefore important to understand the potential economic benefits for the province and the country of investing in new nuclear power generation.”
         The CBC collaborated with OPG to analyze the economic impact and fiscal benefits of building and operating four SMRs at the Darlington site. It found that the SMRs would have a significant positive impact on the Ontario and Canadian economies. Ontario would reap eighty nine percent of the economic benefit associated with the project.
         Each SMR constructed would increase GDP by almost two billion seven hundred million dollars and provide five hundred jobs annually over the sixty-five year period. In addition, the amount of tax revenues accruing to all levels of government is expected to be about three billion five hundred million dollars over the next sixty-five years. This includes plant construction and operations. The estimated number of jobs created by the project will be about one hundred and thirteen thousand jobs provincially and one hundred and twenty-eight thousand jobs nationally.
         The CBC found that “The economic impact, or the ratio of increased GDP to spending (the ‘economic multiplier’) is 0.82 – each dollar spent would increase Canadian GDP by CAD0.82 across the total lifespan of the technologies.”
         On October last year, OPG submitted an application to the Canadian Nuclear Safety Commission (CNSC) for a license to construct a GE Hitachi Nuclear Energy (GEH) BWRX-300 at the Darlington site. This license is required before any nuclear construction work on the SMR can start. Site preparation has already begun at the site. OPG intends to make a construction decision by the end of 2024. Construction of the reactor is scheduled to be finished by late 2028. The supply of power to the Ontario grid should start in 2029.
         The Ontario government announced last July that it is working with OPG to start planning and licensing for three additional BWRX-300 reactors at Darlington. Subject to Ontario government and CNSC regulatory approvals on construction. The additional SMRs could come online between 2034 and 2036. This scheduling would permit OPG to apply earnings from the construction of the first SMR to deliver cost savings on subsequent SMRs. Constructing multiple units will also permit common infrastructure such as cooling water intake, transmission connection and control room to be used by all four units instead of just one, which would further reduce cost.
         Ken Hartwick is the OPG President and CEO. He said, “Being the first North American mover of this innovative technology positions Ontario as a world leader in nuclear and a welcoming destination for new business. Our plan to construct four new reactors at Darlington will also generate opportunities across Ontario and Canada as suppliers of nuclear components and services have an opportunity to expand to serve the growing SMR market here and abroad.”

  • Nuclear Reactors 1293 – The European Council Is Working On Reforming Their Electricity Market Design

    Nuclear Reactors 1293 – The European Council Is Working On Reforming Their Electricity Market Design

         Following months of negotiations, the European Council (EC) has reached an agreement on a proposal to amend the European Union (EU) electricity market design. They agreed to include existing nuclear plants in the reform. The agreement could result in France dropping a scheme forcing state-controlled utility EDF to sell part of its nuclear energy production to competitors below market-level prices.
         The EC stated that the reform aims to “make electricity prices less dependent on volatile fossil fuel prices, shield consumers from price spikes, accelerate the deployment of renewable energies and improve consumer protection”. The proposal is part of a wider reform of the E.U.’s electricity market design. This reform movement also includes a regulation focused on improving the E.U. protection against market manipulation through better monitoring transparency.
         The EC said, “The reform aims to steady long-term electricity markets by boosting the market for power purchase agreements (PPAs) generalizing two-way contracts for difference (CfDs) and improving the liquidity of the forward market. The Council agreed that member states would promote uptake of power purchase agreements by removing unjustified barriers and disproportionate or discriminatory procedures or charges. Measures may include among other things, state-backed guarantee schemes at market prices, private guarantees, or facilities pooling demand for PPAs.”
         The EC is made up of representatives of the governments of E.U. member states. They agreed that two-way contracts for difference (CfDs) would be the mandatory model used when public funding is involved in long-term contracts with some exceptions. These contracts would apply to investments in new power-generating facilities based on wind energy, solar energy, geothermal energy, hydropower without reservoir and nuclear energy.
         The EC also agreed to remove the temporary nature of capacity mechanisms, support measures that member states can introduce remunerate power plants in order to guarantee medium and long-term security of electricity supply.
         The European Commission adopted the proposals on the reform of the E.U.’s electricity market design on the 14th of March. But, a dispute between France and Germany over the role of nuclear power in European climate action has dominated negotiation for months.
         Under the terms of the agreement, France will now be able to finance the extension of the operation of its existing fleet of nuclear reactors with two-ways CfDs. This is in line with the Commission’s initial proposal.
         Currently, under the so-called Regulated Access to Incumbent Nuclear Electricity (Accès Régulé à l’Electricité Nucléaire Historique, ARENH) mechanism set up to foster competition, rival energy suppliers can buy electricity produced by EDF’s fleet of French nuclear power plants that were commissioned before the 8th of December 2010. Under this type of contract, between July 2011 and December 2025, suppliers can buy up to one hundred terawatts representing twenty five percent of EDF annual nuclear production at a fixed price of forty-seven dollars per megawatt. EDF operates fifty-seven reactors in France. The combined capacity of these reactors is about sixty-two gigawatts which is about seventy-five percent of the country’s electricity,
         Under the agreement reached by the EC, the ARENH mechanism could be replaced by CfDs with it expires at the end of 2025. The current agreement has resulted in lost earnings for EDF.
         The EC’s agreement will serve as a mandate for negotiations with the European Parliament on the final shape of the legislation. The outcome of the negotiations will have to be formally adopted by the EC and the Parliament.
