Simply cost. If the plants started in the early 2000s would have been delivered on time and budget they would be a huge part of the transition today. Now nuclear costs 3-5x more compared to renewables and is simply not relevant. > "

Which is why oil production without a gas connection tends to flare the methane. With the renewable transition we will in a not too distant future just leave the oil in the ground instead. https://www.iea.org/reports/fl

For the professional work I have done in Rust the compile times are workable when using cargo workspaces and incremental compilation. Making sure to when possible work directly in a member crate compiling only that for the iteration cycle.

It is windier in the winter months, so what is needed is geographical decoupling through interconnections. Then overbuilding and curtailment definitely is a workable solution. The Baltic sea is also definitely workable for off-shore wind. N

Sadly the problem is that HN is not up to date on current research and economics, nuclear proponents argue like it's 2005-10 and that nothing has changed. Similarly to how you are characterizing the arguments. At that time starting up

Olkiluoto 3 is built by a private company to provide power for a consortium of industry companies, no lowest bidder in sight. Still the same issue though, wonder if it's nuclear that is hard or public procurement? https://en

Base load exists on the demand side, it does not exist on the producer side. Base load on the producer side is simply a made up term because the most inflexible power plants of the 1970's were also the cheapest, and thus matched it.

With Areva, or rather the French tax payers, eating a loss of €5.5 Billion. Include those in the number and you end up a tad bit lower than Hinkley Point C which sits at ~€120/MWh.

Definitely, but how do you feel about locking that in for the next 35 years? Given that the wholesale price usually hovers around €30-50/MWh depending on energy mix.

You mean spending over 10 years importing 15 TWh a year extra because surely next year this reactor will be ready? Also remember that it produces power at around €100/MWh if you include the loss Areva took. Any year but this year and t

Nuclear has a 15-20 year delay from political decision to generating power. Color me surprised if there's still an ongoing energy crisis in Europe by 2037-42.

Could be interesting if they couple it with a Closed Cycle Gas Turbine [1] and a tiny steam plant, like the gas CCGT plants of today. Then the heat engine part should see similar, or even higher, efficiencies compared to gas based CCGT plan

Great that the alternative is renewables then. Arguing against fossil fuels is a strawman. You also have to consider what you need to get that 1kg of U-235 and building your huge power plant. This is called doing a life-cycle analysis. In t

Renewables are the future. Impossible to beat the simplicity of a solid state panel, or axle directly into a generator of wind. We are simply in the awful transitionary phase right now. It's not like starting up another Virgil C. Summe
