Rolls-Royce pressurised water reactors have powered British nuclear subs since 1966, however small modular reactors (SMRs) aren’t but confirmed at scale anyplace on land (Rolls-Royce named winning bidder for UK small nuclear reactors, 10 June). Solely three are working worldwide: two in Russia, one in China. Argentina is establishing the world’s fourth; is Labour merely eager to maintain up with historic geopolitical rivals (Sizewell C power station to be built as part of UK’s £14bn nuclear investment, 10 June)?
The Institute for Vitality Economics and Monetary Evaluation (IEEFA) reported precise cost overruns of 300% to 700% for all 4 tasks. Rolls-Royce claims prices of £35 to £50 per MWh; so ought to we triple this? The federal government says the SMR undertaking would create 3,000 new low-carbon British jobs, however at what value? The power secretary, Ed Miliband, can’t know the true prices but, and three reactors doesn’t scream “economies of scale”.
But £2.5bn is already 10 occasions greater than Nice British Vitality has invested into easy, low-cost rooftop photo voltaic, which democratises power financial savings. The true value of renewables should think about intermittency and balancing prices, however why not make investments extra in flexibility by means of distributed renewables and grid-scale storage? And what of power safety? SMRs might mitigate towards Putin snipping offshore wind cables, however elevated reliance on imported uranium, and a heightened nuclear waste safety risk, are vital dangers.
Final Might, the IEEFA concluded that SMRs “are nonetheless too costly, too gradual and too dangerous”, and that we “ought to embrace the truth that renewables, not SMRs, are the near-term answer to the power transition”. Has this really modified? The local weather disaster requires scaling all possible options as quick as potential, however, with restricted capital, we must always prioritise people who make financial sense at the moment.

As Nils Pratley says, Nice British Vitality’s price range has been nuked to divert funding away from native power initiatives (11 June). However let’s get away from the concept SMRs are a cutting-edge expertise. Rolls-Royce is proposing a 470MW reactor, the identical measurement because the first-generation Magnox reactors. Their “small” modular reactor, if it ever emerges, will use the acquainted technique of producing numerous warmth in a really complicated and costly method, to be able to boil water and switch a turbine. It’s going to bequeath but extra radioactive waste so as to add to the burden and threat at Sellafield.
Within the meantime, if authorities SMR funding continues, it takes cash away from alternatives for cutting-edge technical and social innovation, discovery and coaching throughout the nation, as colleges, hospitals, group teams, community operators and all of us become familiar with renewables-based techniques. This kind of innovation is critical, it’s already benefiting us and it wants full-on authorities assist quite than uneasy compromises with an more and more redundant nuclear trade.

I’m a Scot who moved to the US in 1982. I returned to the UK seven years in the past. In my time within the US, I labored with just a few contractors as a chemist and well being and security supervisor on plenty of environmental clean-up tasks, chemical, organic and nuclear. The nuclear clean-up websites I labored on immediately and not directly had been Hanford in Washington state, and Rocky Flats, Colorado.
The multibillion-dollar Hanford cleanup is ongoing. A lot of the issues there are on account of gross mismanagement of nuclear waste in the course of the chilly conflict.
I very a lot consider in wind, photo voltaic and different environmental options to power manufacturing. I’m cautiously supportive of small‑scale nuclear power, however outraged by this authorities’s failure to incorporate the costs of the disposal of past, present and future nuclear waste in its assist of “low-cost power”.
Has Ed Miliband taken into consideration future waste administration points? Google Hanford cleanup to see the true expense. Can we belief this and any future authorities to guard the atmosphere, public well being and the taxpayer from future nuclear “value overruns”?

The extra I learn in regards to the authorities’s nuclear intentions, the extra it appears like HS2 yet again, ie one other monetary boondoggle. The place are the detailed costings? What’s our expertise with value overruns, eg at Hinkley Point C? What’s the abroad expertise with pressurised water reactors (the type proposed for Sizewell C) at Olkiluoto, at Flamanville, at Taishan? Uniformly unhealthy in all circumstances, really.
Irrespective of which means you take a look at this, viz the longer term value overruns, the info that we shoppers might be on the hook for them, that reactors are by no means constructed on time, that nuclear wastes are unaudited, that we now have to import all our uranium, that the UN’s Intergovernmental Panel on Local weather Change acknowledged in 2023 that renewables are 10 times better than nuclear at decreasing carbon emissions, all level to a remarkably poor determination by the federal government, unhappy to say.
