New-wave reactor technology could kick-start a nuclear renaissance — and the US is banking on it | CNN
www.cnn.com
The US government and companies are plowing billions into small modular reactors. China is leading in the tech, Russia is making almost all the fuel. The US is playing catch-up.

Off the Siberian coast, not far from Alaska, a Russian ship has been docked at port for four years. The Akademik Lomonosov, the world’s first floating nuclear power plant, sends energy to around 200,000 people on land using next-wave nuclear technology: small modular reactors.

This technology is also being used below sea level. Dozens of US submarines lurking in the depths of the world’s oceans are propelled by SMRs, as the compact reactors are known.

SMRs — which are smaller and less costly to build than traditional, large-scale reactors — are fast becoming the next great hope for a nuclear renaissance as the world scrambles to cut fossil fuels. And the US, Russia and China are battling for dominance to build and sell them.

    Vogtle 3 & 4 are AP1000s. Construction started in 2013 (preliminary work had started before this, but a design change halted it). Unit 3 was originally supposed to complete commissioning in 2017, but only happened last year. Unit 4 should be online this year. The initial $12B budget went to $14B at the start of construction, but will end up somewhere over $30B.

    V.C . Summer in South Carolina has a similar project with two AP1000s. The initial budget was $9B, but the project was cancelled while under construction when projections put the total cost over $23B.

    There have been 6 EPRs built, Flamanville-3, Olkiluoto-3, Taishan-1 & 2, and Hinkley Point C (2 units).
    All of them are/were massively over budget and behind schedule.

    Olkiluoto started construction in 2005, was supposed to complete commissioning in 2010, but only came online last year. Costs went from €3B to somewhere over €11B, the contract ‘not-to-exceed’ amount.

    Flamanville started construction in 2007, was supposed to complete commissioning in 2012, but is projected to complete commissioning late this year. Costs went from €3.3B to somewhere over €20B.

    Hinkley Point C is still under construction. It’s difficult to put an actual start date because a pile of preliminary site prep work happened prior to real construction starting. Concrete was poured in 2016 though and it was supposed to be operational in 2023. They’re now estimating 2028 at the earliest. Costs have gone from £16B to and estimated £35B.

    Taishan 1 & 2 started construction in 2009/10 and went online in 2018/19, roughly 5 years late. Unit 1 had to be taken offline for a year due to faulty fuel bundles. Both units have had reliability issues. Costs ended up at the equivalent of $7.5B, almost double the original estimate.

      TBF the EPR is just a horrifically complex design. It’s no wonder they all sucked.
