Two figures are enough to understand the scope of the British challenge: 38,000 million investment pounds and six million homes fed with nuclear electricity for sixty years. This presents Sizewell C, the center that Downing Street describes as a clean energy and employment engine. His detractors, on the other hand, see it as a financial well and the last attempt to give life to a nuclear design so complex that in France it already call it “the monster.” The crown jewel. The objective of the British government is to double the nuclear capacity of the country by 2050 and guarantee a stable supply of low carbon energy. Sizewell C, With two EPR type reactors (European pressurized reactor), is the key piece of that strategy. According to the BBCthe project is the successor of Hinkley Point C, in Somerset, which accumulates a decade of delays and a runaway cost: more than 18,000 million pounds planned in 2010 to about 46,000 million today. Minister Rachel Reeves declared The Guardian that investment is “a powerful support to the United Kingdom as the best place to do business and as a global center of nuclear energy.” Instead, Henri Proglio, former director of the French electric EDF – developmentator of the project -, assured the Financial Times that the reactor design is “scary” and “almost impossible to build.” Faced opinions. The detractors have it clear. Proglio describes it as “a machine with more reinforcement rods than concrete.” Another engineer, Also cited in the FThe spoke of a “colossal error.” And Greenpeace warned the BBC That this time will be taxpayers, not EDF, who pay the inevitable cost overruns. But there are also moderate voices. Tony Roulstone, Professor of Cambridge and exejecutive of Rolls-Royce, declared to FT That Sizewell could be ready “one or two years before Hinkley” and cost 20 % less. Thanks to the fact that much of the design is already tested since the supply chain was consolidated in Somerset. There are already works in Suffolk. The project is not just paper. In Suffolk, 1,700 operators are already working in preliminary works, According to the Financial Times. The first one: a perimeter wall 55 meters deep and 3 kilometers long to drain the marsh before placing the foundations. In addition, Hinkley errors will be avoided. This time the concrete structures will be pregnant in workshops and not in the work, which should accelerate the deadlines. Even so, the official calendar – entered into operation in the middle or end of the 2030s – raises doubts. Flamanville, in France, and Hinkley have shown that deadlines in projects of this type are usually wet paper, As Critica Nils Pratley in his column for The Guardian. It is very complex. It is more complex than it seems to the naked eye. EPR are nuclear reactors of generation III+, the result of Franco-German collaboration between EDF and Siemens. According to World Nuclear Associationare designed to offer a net electrical power of between 1,600 and 1,650 MW, although they can reach 1,770 MW. In addition, they incorporate advanced security measures: double containment, four independent cooling systems, a Core Catcher to catch the nucleus in case of merger, and structural capacity to resist impacts and earthquakes, in addition to diesel generators and backup batteries that guarantee operability to multiple failures. They also stand out for greater energy efficiencyconsuming up to 17% less fuel than old reactors and producing up to 14% more energy. All this with a projected life of 60 years. This technical complexity is, at the same time, a strength in terms of safety and efficiency, and a challenge for the delays and costs that it has shown in its construction. The invoice reaches the British pocket. The cost of the central already exceeds twice the first estimates, According to BBC. The majority (36.6 billion) will be covered with public debt through the National Fund of Wealth. While the financing is distributed among the State (the largest shareholder with 44.9%), followed by the Canadian Caisse (20%), Centrica (15%), EDF (12.5%) and Amber Infrastructure (7.6%). The great novelty is the “Regulated Assets Base” model (Rab) in which households will begin to pay £ 1 per month in their electrical invoices for at least a decade, Julia Pyke explained to the BBC. This scheme mainly protects investors, As Nils Pratley recalled in The GuardianCentrica ensures returns of more than 10% even if the costs reach 47.7 billion pounds; Any excess will be assumed by taxpayers. France already tried. Although with problems. The first French EPR reactor, Flamanville 3, in Normandy, connected to the network In December 2024 after 12 years of delays and with a final cost of € 13.2 billion, four times budgeted. As explained in Financial Timesthe French experience forced to redesign the concept, so EDF no longer prioritizes the EPR, but the EPR2, a simplified and cheaper version that hopes to build in six units here to 2038. Meanwhile, in China they have shown that its Taishan center that has operated for years with an EPR of 1.75 GW, is one of the most powerful reactors in the world. A continent that turns nuclear. The British bet arrives in a contradictory European context. Germany He closed his last central in 2023 and Spain plans to close them in 2027. France, on the contrary, Maintain nuclear as a pillar (70 % of its electricity) and accelerates new EPR2 projects. The board moves: under Chancellor Friedrich Merz, Germany has stopped blocking France and accepts that the nuclear receives the same treatment as renewables in EU legislation. The agreement includes giving “green” status to pink hydrogen and opens the door to European financing, although Austria continues against and countries such as Belgium and the Netherlands reevaluate their policies. In the midst of this continental debate, the United Kingdom, outside the EU, advances alone with Sizewell C: an EPR that even EDF has relegated in favor of the EPR2, while in Europe the SMR and nuclear fusion gain space. … Read more
