Earlier quoted context omitted.

Probably on the basis of not expecting a rapid increase in people wanting to become nuclear engineers...

That would contradict "even if she wanted to, France couldn't". If she wanted to, France could make nuclear engineering a highly-paid profession with strong job security. It would just cost more money.

I have serious doubts that would ever happen. Everything is gridlocked for programs like that in France.

The CO2 cost is low though. You don’t need to fire coal and gas power plants when it’s dark and not windy.

One would hope that by 2050 energy storage and/or long-range transmission will be a non-issue for renewables, rendering this argument moot.

Given the latency for big projects we’d likely have at least a somewhat clear idea of what that storage would be approximately now. Do we?

It's impossible to make binding long-term promises in a democracy. Voters are allowed to change their minds, and the risk that they do that and completely destroy nuclear engineering as a career option is always present.

Something like software engineering is a much safer career option, because the risk that your country will categorically ban it is pretty low. And because it doesn't tie you to a small number of possible employers or force you to live in a specific location.

My dad who passed away some years ago on my 50th birthday, worked on the design for the AGR for many, many years. Fond memories of him picking me up from school and excitedly telling me the interesting problems he had to solve that day on the walk home. A lovely way to start my day - thank you for sharing.

I went on a tour round Torness a couple of years ago and it's a fantastic engineering marvel to mosey around.

A few things stand out, like the old-tech ring binders and Windows 95 screensavers on CRTs. The safety focus was clear. Nothing was done without a risk assessment, and the young apprentice who was helping with our tour was given a telling off by the tour staff as he wasn't holding the handrails - as had clearly been drummed into them.

What really struck me was how many people were involved in running the plant. I don't know how it compares to similarly sized gas plants, but there were hundreds and hundreds of people employed - mostly in project management/safety roles. I wonder how it compares to how many folk are employed in renewables, we have a lot of wind power here now.

It's a shame that cracks have started to form in the reactors so the plants will be shutdown earlier than planned. It looks like tours are suspended for Covid, but go round if they open up again before shutdown!

"some embedded controllers in racks in the auxilliary deisel generator control rooms have EPROMs which have been known to be erased by camera flashes in the past" echoes of the Raspberry Pi camera flash reboot story, 13 years apart :) https://hackaday.com/2015/02/08/photonic-reset-of-the-raspbe...

Being apparently able to erase old style glass top EPROMs with a camera flash is perhaps a bit less surprising than random power components messing up. UV light exposure is how you erase them normally, although you normally use lower light levels for longer, not a short bright camera flash.

I do think they need to buy higher grade sticky labels to cover the window with though. :-)

Always a treat to read something by Charles Stross. Seems like Accelerando was required reading for the previous generation, is it still? I was not familiar with the UK advanced gas cooled reactors, which use CO2 to cool the core and transfer heat to the steam. From the name it seems to be gas and not supercritical CO2 although I may have that wrong. Power generation is the one topic that makes thermodynamics crystal…

I was very disappointed when I finally learned how a nuclear power plant worked because I assumed there was some really cool way to turn nuclear energy into electricity (apparently this is still challenging to do at power plant scale).

The central cylindrical space in what was the Scottish Nuclear headquarters was designed to be the same size as an AGR reactor (each AGR plant having two reactors) - which I thought was rather cool.

"nothing like this will be built again" ITER / DEMO / PROTO plants planned to eclipse everything previous in scale. And with nuclear fission now classified as green tech by the EU, maybe the political will is finally here ;) https://www.france24.com/en/live-news/20220109-europe-nuclea...

ITER will generate no power. No liquid-metal neutron-absorber "blanket", no steam piping, no turbines. DEMO / PROTO will, if not cancelled, be absolutely monstrous, but generate no more power than a wee fission plant. Until they destroy themselves with their own neutron flux. (They should build them underground, so they will already be buried when it is time to abandon them.) It is inconceivable that any such project…

Unless we get serious about exploring the outer planets, then fusion will be a must have.
