The vessel was forged and machined at the company\u2019s Saint-Marcel site near Chalon-sur-Sa\u00f4ne.<\/p>\n<p>According to the details published with the announcement, the vessel weighs about 500 tonnes and is roughly 13 metres long. It is designed for the EPR (European Pressurised Reactor), a third\u2011generation nuclear design planned for Hinkley Point C\u2019s two units.<\/p>\n<h3>Why a reactor pressure vessel is so critical<\/h3>\n<p>In simple terms, the reactor pressure vessel is where the reactor core will sit. It must contain the fuel assemblies and control systems, while holding high\u2011pressure coolant water in extreme operating conditions.<\/p>\n<p>The source notes that temperatures inside can exceed 300\u00b0C and pressures can top 150 bar. The metal is also expected to resist neutron bombardment for decades\u2014up to 80 years\u2014raising the stakes for quality control in forging, welding, machining and inspection.<\/p>\n<h2>How it travels: barge, sea crossing, then heavy-haul convoy<\/h2>\n<p>Moving a component this heavy is a logistics operation in itself. The vessel\u2019s planned route involves multiple stages: it leaves the factory by river barge, then crosses the Channel by sea transport, before completing the final stretch via heavy-haul road convoy to the Hinkley Point C construction site on the Somerset coast.<\/p>\n<p>Its arrival also follows another visible milestone at the site: the reactor dome for Unit 2 had already been installed shortly before the pressure vessel departed France.<\/p>\n<h2>Hinkley point C: a new nuclear build after decades of pause<\/h2>\n<p>Hinkley Point C is the UK\u2019s first new nuclear power plant in more than 30 years. On-site construction began in 2018 and the project will ultimately include two EPR units.<\/p>\n<p>Each unit is rated at 1,630 MW, making it more powerful than any currently operating British reactor, as highlighted in the source article. Together, the two units are expected to supply around 7% of the UK\u2019s electricity demand.<\/p>\n<h3>Timelines and milestones mentioned so far<\/h3>\n<ul>\n<li>Main construction works began: 2018<\/li>\n<li>Reactor dome installed on Unit 1: late 2023<\/li>\n<li>Reactor vessel 1 reached the UK: 2023; installed: December 2024<\/li>\n<li>Reactor vessel 2 completed in France: November 2025<\/li>\n<li>Planned commercial operation: Unit 1 in 2030; Unit 2 in 2031<\/li>\n<\/ul>\n<h2>Cost pressure, long lifetimes, and what EDF says comes next<\/h2>\n<p>The project\u2019s price tag remains central to the debate. The article cites official estimates at \u00a331\u201334 billion in 2015 money, higher than earlier expectations. EDF, which leads the project, has argued that the costs reflect \u201cfirst-of-a-kind\u201d challenges in the UK and the scope of the build.<\/p>\n<p>Supporters also point to longevity: once operational, Hinkley Point C is expected to run for 60 years or more, with the possibility of extensions subject to regulatory approval.<\/p>\n<h2>The next giant parts: steam generators are also in the pipeline<\/h2>\n<p>The pressure vessel is only one major ingredient of an EPR. Framatome is also producing steam generators\u2014towering components that transfer heat from the reactor\u2019s primary circuit to a secondary loop that produces steam for the turbines.<\/p>\n<p>Each steam generator is around 25 metres tall and weighs about 520 tonnes, according to the source. The first steam generator for Hinkley Point C arrived in Somerset in May 2024 and was installed in Unit 1 two months later. For Unit 2, two steam generators have already left the factory, with remaining deliveries scheduled by 2026 to match the installation plan.<\/p>\n<h2>Why the shipment matters for the UK\u2019s energy strategy<\/h2>\n<p>Beyond the engineering, the delivery highlights a broader policy shift. With wind and solar supplying record shares of electricity but varying with weather, the UK is looking again at nuclear power as a low\u2011carbon source that can run consistently.<\/p>\n<p>That strategy comes with trade-offs\u2014long build times, heavy upfront capital costs, and politically sensitive issues such as waste and decommissioning. Still, the arrival of the Unit 2 pressure vessel underlines that the UK is committing to large-scale nuclear as part of its future power mix.<\/p>\n<h2>Summary<\/h2>\n<ul>\n<li>Framatome completed Hinkley Point C Unit 2\u2019s reactor pressure vessel on 28 November 2025.<\/li>\n<li>The vessel weighs about 500 tonnes and is roughly 13 metres long.<\/li>\n<li>Hinkley Point C will use EPR reactors rated at 1,630 MW per unit.<\/li>\n<li>Construction at Hinkley Point C began in 2018; commercial operation is planned for 2030 (Unit 1) and 2031 (Unit 2).<\/li>\n<li>Steam generators\u2014about 25 metres tall and around 520 tonnes each\u2014are also being delivered, with more shipments planned by 2026.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A 500-tonne reactor pressure vessel has left France for Somerset, marking a major milestone for Hinkley Point C\u2019s second EPR unit and the UK\u2019s push for long-term low\u2011carbon power.<\/p>\n","protected":false},"author":6,"featured_media":1918,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[],"class_list":["post-1908","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"_links":{"self":[{"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/posts\/1908","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/comments?post=1908"}],"version-history":[{"count":2,"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/posts\/1908\/revisions"}],"predecessor-version":[{"id":1917,"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/posts\/1908\/revisions\/1917"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/media\/1918"}],"wp:attachment":[{"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/media?parent=1908"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/categories?post=1908"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.ecoportal.net\/uk\/wp-json\/wp\/v2\/tags?post=1908"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
