By stewartb ‘At the time of writing there are only two SMRs actually operating – one in Russia and one in China. For this reason alone, we must question reliance on a technology not yet fully tested, as the basis for a national programme of work.’ So it’s a novel technology. The OECD in 2024 recognised three SMRs as operational, with over 50 SMR technologies currently still under development. (https://www.ansto.gov.au/news/small-modular-reactors-an-overview) If a company or nation state has relevant indigenous technological capability, an energy need AND national ambition to develop and then sell as exports SMRs, one might see the sense of being … Continue reading Does Scotland really need SMRs for a resilient energy system?

By stewartb It’s clear from statements made, if Anglo-British political parties gain power in Holyrood after the 2026 election, Scotland in Union will see a new generation of nuclear power plants (large ‘conventional’ and/or small modular reactors) built here. Ian Murray MP, Secretary of State for Scotland, July 4, 2025 stated: “In other parts of the UK, the UK Government is driving forward nuclear power, as are countries across Europe and indeed the world. But in Scotland the Scottish Government clings to its ideological objection to new nuclear sites. That means that Scotland is being left behind, missing out on … Continue reading The Nuclear Decommissioning Authority on existing UK nuclear sites: ‘all land dedesignated or reused’ by 2380 – but sooner at Dounreay, by 2334!

By Anonymous When I questioned Small Modular Reactors, DeepSeek said You’re absolutely right to question the readiness of Small Modular Reactors (SMRs)—while they are often touted as a potential solution for clean energy, they remain largely unproven at scale, with significant uncertainties around cost, deployment timelines, and real-world performance. Key Issues with SMRs Today1. Limited Real-World Deployment 2. Unclear Cost Competitiveness 3. Regulatory & Supply Chain Hurdles 4. Still Produce Nuclear Waste Should Scotland Wait for SMRs? Conclusion SMRs are not yet a proven solution—Scotland would be wiser to invest in tidal expansion, storage, and grid flexibility while monitoring SMR developments. If SMRs eventually prove cost-effective … Continue reading Impartial intelligence confirms that Labour’s Small Nuclear Reactor strategy is based on none in operation in the West, no concrete order and two already cancelled in France and the US due to soaring costs

Professor John Robertson OBA Frances McKie has just alerted me to this reserved report from Reuters on the Civaux 2 nuclear reactor in France: PARIS, June 11 (Reuters) – European power contracts jumped on Wednesday on concerns France might have to reduce its nuclear output after the industry regulator said it had identified “hints” of possible stress corrosion in a reactor. The ASNR watchdog said testing had highlighted possible defects in the Civaux 2 reactor, but that there was no confirmation of corrosion at this stage and more testing was required. https://www.reuters.com/business/energy/report-defects-french-nuclear-reactor-civaux-2-lifts-european-power-market-2025-06-11/ On it’s own and with that wording, it … Continue reading Reliability of nuclear energy takes another blow as France fears return to 2022, when 57% of all reactors were offline due to corrosion

stewartb ‘Reforms to planning rules will clear a path for smaller, and easier to build nuclear reactors – known as Small Modular Reactors –to be built for the first time ever in the UK.’ Just how many SMRs will be built in the UK…. and why? What will determine the number? From Nuclear Engineering International magazine (NEI, May 15, 2025): ‘Is the UK ready to give the SMR go-ahead?’ (https://www.neimagazine.com/analysis/is-the-uk-ready-to-give-the-go-ahead/ ) ‘The UK government wants to open the door to fleets of small modular reactors across the country. To achieve that, it has to sweep away some longstanding barriers created by electricity network rules … Continue reading Telegraph – Economics of Labour’s Small Modular [Nuclear] Reactors could prove hard to justify

Professor John Robertson OBA From The Hill two days ago: President Trump on Friday signed executive orders that seek to quadruple the nation’s nuclear power, including by cutbacks to health and environmental considerations.  In one such executive order, Trump laments that the Nuclear Regulatory Commission’s (NRC) radiation safety standards are too stringent. https://thehill.com/policy/energy-environment/5316211-trump-executive-orders-nuclear-power/ From From PM Starmer via GOV.UK on 6 February 2025: More nuclear power plants will be approved across England and Wales as the Prime Minister slashes red tape to get Britain building – as part of his Plan for Change. Reforms to planning rules will clear a … Continue reading Trump to ape Starmer in scrapping ‘red tape’ for new nuclear power and put all our lives at risk
