Shows what can be done with just a little learning curve for nuclear
https://en.m.wikipedia.org/wiki/Yangjiang_Nuclear_Power_Station
Unit 1. 5 years 3 months
Unit 2. 6 years 0 months
Unit 3. 4 years 11 months
Unit 4. 4 years 1 month & 3 weeks :T
A different design was used for unit 5 & 6 so a new learning curve
Unit 5. 4 years 10 months
Unit 6. 5 years 8 months
There is every reason to believe that they can be built even faster than the 4 years 1 month 3 weeks of unit 4 maybe even as quick as 3 years especially if China or India standardise to one or two designs and build many 6+ reactor stations
Nuclear can be affordable and quick if you want it to be
And the Chinese are still new at this they have some 40 reactors of many different designs
Pick one or two good designs and mass build 200+ and they will get very good at building them
Perhaps even have larger nuclear power stations with 10 reactors at a site

Fukushima Daiichi Nuclear Power Plant had six reactors at one site. They planned to have eight reactors at one site. None of them are currently operational.Shows what can be done with just a little learning curve for nuclear

At Chernobyl they planned to have six reactors at one site (your magic number?) and had already started building the last two.7.25 kWp PV system (4.1kW WSW & 3.15kW ENE), Solis inverter, myenergi eddi & harvi for energy diversion to immersion heater. myenergi hub for Virtual Power Plant demand-side response trial.0 -

And ? Chernobyl was stupid on many levels. No containment vessel positive void coefficient safety systems off. Nothing like that could happen again.
Fukushima was just an over reaction there are more deaths associated with the needless evacuation than the actual radiation

The more you build of one design the quicker and cheaper it becomes. This should be obvious and is true for all types of construction including homes. The more you build in one location the cheaper again0 -
Nothing like that could ever happen again? Sounds good to me. I suggest you build it in your back yard.And ? Chernobyl was stupid on many levels. No containment vessel positive void coefficient safety systems off. Nothing like that could happen again.

OK
Watch the youtube video it's informativesix reactors at one site (your magic number?)
There's no magic number but the more you build especially at one site, the better you get at it
Build 20 at one site if the local demand can handle it and you'd perhaps have something like
Unit 1-2 in 5-6 years
Units 3-4 in 4-5 years
Units 5-6 in 3-4 years
Units 7-20 in 2-3 years
Average 3.1 years and a cost of $1 billion per reactor (compared to $1.7 billion at the Yangjing plant. Simply building faster reduces 'costs' because the plant starts earning sooner)
Such a power station could produce an immense 200TWh a year
If that price point can be achieved you are looking at sub $10/MWh.....
BTW I don't think we could get to such prices in the UK or Europe / USA because wages are higher
But perhaps £3 billion per GW is possible, the last reactor built on the UK cost £2 billion (£5.3 billion in today's money) and was built in 8 years that was a single reactor no recent experience and it was 1.2GW reactor so £4.4 billion per GW therefore £3 billion per GW sounds plausible0 -
If that was the UK then it would be
25 years
5 Public Inquiries
3 Judicial Reviews
6 different protests groups picketing the site
4 companies pulling out due to escalating costs
6 different governments promising money and failing to deliver
And the result is not a single reactor built0 -

Or, just throwing it out there, 2 reactors under construction, that may start generating around 2028, at a cost of £102/MWh (today's cost but index linked to commissioning and for 35yrs after), v's on-shore wind and PV at half that price today, and off-shore wind at £65/MWh in 2023. [Edit - £65 in today's money, but for delivery in 2023. M]
Plus all the FF emissions that result from the time differential of RE v's nuclear build outs.
In short, just another 'squirrel' thread to 'knock' RE, when it's already won the economic argument (having won the green and ethical argument long ago).Mart. Cardiff. 5.58 kWp PV systems (3.58 ESE & 2.0 WNW)

The last nuclear reactor built in the UK was completed in 1995
Producing power for the grid February 1995
licence to proceed with construction August 1987
7 years 6 month and it cost £4.4 billion per GW (in today's money)
This was the first and only PWR the UK has built so if we had continued to build more there is every reason to believe subsequent units would have been faster (which in itself lowers cost) and cheaper0 -

Must all roads lead to discussing your wind?
First 1 TWh from wind power in Germany 1995
24 years later in 2019 today Germany still burning significant quantities of brown and black coal
And in another 19 years they may phase out coal
A 'rapid' 43 years.....
First 1 TWh from nuclear in France February 1988
48 reactor built and completed by May 1989
<11 years...
48 reactors like sizewell B could produce annually 467 TWh which for comparison is 139% of UK useage0 -
As can be seen individual reactors can be built in 4 years 1 month 3 weeks (and there is every reason to believe this can be done quicker too if you mass produce one or two designs)
The argument of nuclear is too slow also fails because you can build them in parallel
This one nuclear power station built 6 reactors and the time from starting the first to completing the last was 10 years and 8 months. works out to one every 21 months on average and that is at just one site
And you can build 20 such sites which is more or less what the French did building 56 reactors in 18 nuclear stations over 15 years. So 15 years to fully decarb electricity and some heating needs too0 -
I don't think reactors built in China or started more than 30 years ago are a good analogue for the UK today. Especially as all the recent reactors built recently in the western world have been massively delayed and over budget (Olkiluoto 3 and Flamanville 3) or abandoned part way through construction wasting billions of dollars after costs had become excessive (VC Sumner). Those would be much better analogues for UK conditions.
If China can genuinely build reactors reliably, quickly and affordably that is good news. I am skeptical though because even though China has the largest nuclear construction program in the world, it's still rather small as a percentage of electricity generation and has increased, and is planned to increase considerably slower than output from new renewables.
I'm skeptical on a world scale because nuclear output is increasing very slowly. If it were the attractive solution its proponents paint, there would be a boom in construction especially in developing countries where electricity demand is rising fast. I do not buy the anti-nuclear conspiracy that "greenies" are blocking nuclear power. It could explain a nuclear phase out in a few rich countries like Germany but it's implausible that "greens" are blocking/limiting nuclear power in India, China, Vietnam, South Africa etc.Solar install June 2022, Bath
