#82I'm glad the article talks about the positive impact this will have on Sizewell C. The UK completely disregards the long term impact of skills and experience lost when debating whether we should do this kind of project.

It takes time to find and develop good people, so hopefully Sizewell C plus Rolls Royce SMR will gain momentum to allow their retention.

Interesting, thank you for that. Do you have a source for that and any context (eg: "not power" time being used for "experiments" related to UK military nuclear uses, etc)?
No context sorry - there are enough experimental reactors in the UK for experimentation without interruption the commercial fleet. What would be interesting is expected vs unexpected downtime, some sort of reliability factor. https://assets.publishing.service.gov.uk/media/5c9a5d37ed915...
It appears approx ballpark with Europe reactors and as if they're designed with a 70% of max load operating target to allow for downtime inspections and statutory fettling, etc.

Thats a very good comparison-- to be fair though, 3.2GW nuclear are comparable to pretty much the whole Dogger Bank (including Sofia/South) at ~8GW (nameplate power), because offshore capacity factor is about ~40% in the UK. Total cost for the wind farm is probably around 20-ish billion $, but the lifetime is likely shorter than the reactor (possibly less than half!). It's surprising to me that the reactor at $35bill…
Do you mean it's competitive due to the longer lifetime? Is the operation cost of the reactor over such a long duration not significant? Also why are you comparing 8gw to 3.2gw? Is it due to peek output? if so won't this be solved by grid level storage?
Yes. Also because maintenance costs are probably somewhat similar-- offshore turbines are still mechanical systems in a very unpleasant environment, after all.
> Also why are you comparing 8gw to 3.2gw? Is it due to peek output? if so won't this be solved by grid level storage?
Yes-- the turbines give you 8GW, but only 40% of the time. Reactor gives you its ~3GW basically all the time. This difference would NOT be erased by storage-- you would need the storage on top of the windpower, but it is not trivial to tell how much storage you really need (electrical grid connectivity can also somewhat compensate, or large consumers that only turn on when energy is cheap...).

Dogger Bank will when fully built-out at a cost of some £11bn. Lifetime cost will be much lower - near 0 staff - no anti-terrorism policing operation - no fuel. If it were onshore, cost would be significantly cheaper and would be able to scale onto the grid and generate revenue (nearly) one turbine at a time as they are installed which makes a massive difference for financing and servicing a debt. Cost wise certainly…
£11Bn is just Dogger Bank A, B, C (which is only 3.6GW total nameplate power, not 8GW)-- but this is in fact where my "~£20Bn total cost" estimate came from :P Maintenance cost for offshore wind is NOT negligible. This is possibly as high as the reactor maintenance cost already by itself. Then, for a fair comparison, you would also have to add costs for improving grid connectivity and/or local battery storage... I'm…
GE's 170 full-time turbine servicing jobs for Dogger Bank phases A, B and C will be based out of the Port of Tyne. That is more staff than I would have guessed, one worker for every 1.6 turbines!

#86As far as I understood it takes so long because UK has some customization requirements which impacted a lot delivery time
That's one of the reasons. Others include, but are not limited to: 1. The EPR is a FOAK build of a new design All of the EPR instances were started before any other instances were completed. FOAK (First of a Kind) builds are notoriously more difficult, costly and risky than NOAK (Nth of a Kind) builds. Think how much more a prototype of car costs than one you get off the assembly line. The difference is not quite tha…

Now, if you look at the price per kilowatt, for instance, Chinese yuan per kilowatt, the, the, the Ap1000 are more expensive than the EPR.
> I haven't been able to find out whether Sizewell C and subsequent will also be EPR2 or whether the UK will stick with its heavily modified EPR.Sticking to the UK EPR. There is no point in building another FOAK for marginal benefit.

thanks for additional contribution! Agree, AP-1000 is extremely cool, China already has 4 reactors with it and more are in building phase

Enough wind + solar + storage to deliver > which gives Hinkley Point C a total output of over 3.2GW. at least 3 GW 24 hours a day, 7 days a week, 50 weeks a year (allowing for some step down in output for maintainance, etc) for some 30+ (?) years.
The UK’s average nuclear load factor for 1970 to 2017 was 67.4 per cent 3 GW 24 hours a day, 7 days a week, 34 weeks a year. or 3 GW 16 hours a day, 7 days a week, 52 weeks a year.
For instance https://pris.iaea.org/PRIS/CountryStatistics/ReactorDetails.... shows Sizewell B has a load factor of 83.1% which is better than the AGR fleet.

No drama, good link, thank you. It appears approx ballpark with Europe reactors and as if they're designed with a 70% of max load operating target to allow for downtime inspections and statutory fettling, etc.

Yeah, that's one point that gets lost in the brouhaha over nuclear cost overruns: Even the most catastrophic nuclear projects are competitive if not better than the best renewable projects. Yeah, I know this sounds like frothing-at-the-mouth nuclear fanboiism, but run the numbers! I did, and once I did I started sounding like a frothing-at-the-mouth nuclear fanboi. ¯\_(ツ)_/¯
Off-shore wind is still scaling to become cheaper and cheaper. In 30 years it might cost much less. How can Nuclear compete?
