Looks promising and I'd have more faith in a Nuke put together in a RR factory than something knocked together by construction labourers on site. RR have been building small nuclear reactors since the mid 1960's. The UK needs something like this for baseload if its going to phase out coal and doesn't want to be too reliant on the next LNG tanker turning up at Milford / Grain.

Couldn’t agree more Nick! coal will be phased out totally by 2025 in the UK there are only 5 left now. There are a number of gas stations that are easy to bring online again if needed, but renewables are making huge inroads into UK power generation.

I still think we need plenty of nukes though The situation worries me less now as the world is awash with gas but its still an import risk. The Uk has to import Uranium but the annual fuel load for a large nuke is about the size of a double decker bus. You can't import years worth of gas in advance. Cold climate countries like the UK need baseload, with little Hydro its nuclear or a return to Coal / Gas. Offshore wind, especially the >10MW turbine farms on Dogger will in effect provide some baseload although I wouldn't risk going over 10% of capacity.

I do not want to destroy your party, but please lets get down to cold facts now: - What are the strong sides of 220/440 MWe reactors in comparison to their grown up friends 1000-1700 MWe ? a) Even if it is some sort of RR science breakthrough ( I do not think so), it can be scalable for 1-1.7 GWe reactors. A lot of stuff, procedures you need in place 220/440 or 1700 nameplate capacity. Economies of scale are really positive here. b) Anybody that can build normal reators 1+ GWe do not build small ones. No smaller than 0.5 GWe reactor in Europe put into use I do not know since when : 30 or 40 years. The advantage of modular is: It gets assembled in a controlled environment by RR Techies who have been building PWR's since the 1960's rather than a disperate bunch of clowns who half the time can't speak each others language. its smaller size means its easier to roll out. You haven't got to shell out £23bn (Hinkley C) over a decade before any money comes rolling in. The price tag on these SMR's is around £2bn and likely to fall if large number of orders come in. To get the ball rolling RR are saying they will build and operate a number in the UK so they obviously have confidence in the product. Quote Share this post Link to post Share on other sites

The benefit of SMRs is that they are easier to integrate in reality; for example they can be installed in old coal fired power-plants sites using much old infrastructure. And likely there are some safety built into this that they are not giving away in the marketing material.. One of the reasons offshore wind got so popular in the UK was that it was realitively easy to implement partly due to lower financial entry barriers by smaller private entities. If RR can overcome the safety then this might actually be the first stepping stone to a revival of Nuclear.

Actually this should end the discussion but lets go further. - RR has no experience in civilian nuclear reactors. Anybody that has experience builds larger reactors. Price tag of 2 bln pounds (very optimistic planning made by company with no experience in civilian nuclear reactors, they usually get, for the first unit recently outside China, South Korea and Russia it has to be multiplied by the factor of 2 or 3) per 440 MW sound like a fantastic business. Plus operating costs at the level of 1 GWe reactors. Just fantastic /sarcasm indicator on. I'd be surprised if any of those 3 would fully pass modern western safety standards. Its apparent the 4 units being built in the UAE do not come with core catchers The UAE is getting 5.4GW for $24 bn (the list price) build with el cheapo slave labour.

Enthalpic + 1,496 January 29, 2020 (edited) Ideally we switch to a truly renewable energy source. Nuclear emits no CO2 but of course it still suffers from the whole "but it takes so much material to build" argument that people use against wind. It's also still a non-renewable resource that has to be mined and extensively refined. Once you add in waste disposal and security risks*** I don't see small-scale stuff working out. *** You can't make a nuclear bomb from one, but blowing up a small reactor with conventional explosives is easy and makes a huge mess (dirty bomb).

This is totally incorrect Marcin a brand new nuke station is currently being built in the UK (Hinckley point C) by EDF (French company) with some financial backing from China ( financial only). you need to do your research properly before posting your BIG FULL STOP as Enthalpic points out Canada also have built nukes. have you not thought the lack of nukes is down to the political push for green energy and not that countries don’t know how to build them? your outright dismissal of RR SMR’s is based on your opinion and summation only. knowing RR as I do as we work closely with them I suspect your opinion is very much flawed regarding safety they help build many nuclear subs for BAE systems especially on the primary core work and have done so for 60-70 years so they know safety! your very wrong on this one Marcin usually your posts are informative or thought provoking, this one is neither 1 Quote Share this post Link to post Share on other sites

Reactor in France will not be grid connected before 2022, and in Finland maybe in 2021, but the schedule was already delayed many times. Simply EdF/Framatome/Areva lacks expertise in executing nuclear construction projects within budget and on time. I do not know what happened in China, what help was provided by Chinese to the French company that allowed the completion of 2 EPR reactors in China. - For purely political reasons (EdF owns all British nuclear power plants and wants to deploy more EPR reactors) it was not possible to choose South Korean ( or Russian or Chinese) company to construct Hinckley Point C so EdF got the job.

Nuclear power plant is the large engineering project, and only South Korea, Russia and China have track record of executing them within budget and schedule in 21st century. I respect historical track record of CANDU designs or EdF designs, but the same as with Egyptian Pyramids, the builders are all dead now. You're a man on an island with this Marcin! You talk about facts but then give misinformation about who is building what, or has the capability to do so. What makes it such a leap from building reactors for a sub (small scale) to building small scale civil reactors? I think you have alluded to large scale projects overrunning and going over budget and that's precisely why RR SMR's are attractive. They're small and powerful and easily scaleable (so can fit most budgets). They also aren't a blot on the landscape which wind power most definitely is. You seem as anti nuclear as Germany. The UK is not just building Hinkley C it is planning for Wylfa and Moorside as well to promote a new modern fleet of nukes. The only thing that will stop it is money or political will, it is NOT technology. https://www.world-nuclear.org/information-library/country-profiles/countries-t-z/united-kingdom.aspx The RR design is utilising its knowledge of small scale nuclear and combining it with the need for smaller reactors that are scaleable in the civil market. I don't think that's a bad idea and a market is certainly there for it. I think your total dismissal of EDF, Framatome, Areva and RR is unfounded. All of these companies have shown they are leaders in their fields (EDF own and operate 58 nuclear stations). All are well respected in the nuclear industry. The large scale builds you mention are at such an astronomical cost that it puts off incumbent governments or gets shelved when a new government comes into power. Where is the return on investment for the incumbent government? That money could be spent on infrastructure, health, or even tax cuts, those are vote winners. Building a large scale nuclear power station isn't, again a plus for RR SMR's. Regarding your point on cost, this is from RR website:- "Plant Economics Detailed and comprehensive cost analysis of the UK SMR, complemented through market demand analysis, has determined that the first of a kind plant is capable of delivering a Levelised Cost of Electricity of around £75/MWh for the initial plant and levels of around £60-70/MWh for mature implementations of the design. This is in line with market expectations and confirms that the proposition is commercially viable" However i think your missing the point on costs, its the initial cost of building and financing a 1GW station compared to an SMR that is so attractive. It costs approx 1/10 of the initial outlay for 44% of the power even if it operates at a more expensive MWh. Dont forget these nukes have a lifespan and you wont get your initial investment back, they also have a huge decommissioning cost which I think you have overlooked. The last point is a political one, the UK (or whichever country) wouldn't be reliant on outside funding (China) or engineering. This gives less political sway to the likes of China in the country that deploys SMR's. You cant put a price on that. We're probably not going to agree on this one, but never mind. 2 Quote Share this post Link to post Share on other sites
Marcin2 + 726 MK January 30, 2020 (edited) Rob, I am very pro-nuclear, I think this is the only scaleable source of low CO2 emissions baseload power generation. I just do not share your optimism in EdF or RR capacities. I would share your optimism when RR will grid connect their first modular reactor. We would know the budget then.

I dont have the expertise to answer this. However I agree with the attached that states that historically nuclear reactors have almost totally been funded by government R&D projects and now there is a real move away from this into the private sector, especially with the 4 main designs that are being worked on. https://www.world-nuclear.org/information-library/nuclear-fuel-cycle/nuclear-power-reactors/small-nuclear-power-reactors.aspx You ask why nobody is building them and yet they are, thats exactly what RR are doing. They have a head start on the rest IMO. It has taken RR years upon years to get to this stage. I agree that RR marketing info is the antithesis of an independent source but it is fairly compelling when you read what they are proposing. One thing is for sure there is a huge market for them and that will mean others will come into this marketplace soon to add competition. The EPR delays were engineering issues as per the attached, China also had delays. https://www.powermag.com/long-delayed-epr-nuclear-plants-face-further-holdups/ I agree when these are completed they will be excellent, safer and more efficient. 1 Quote Share this post Link to post Share on other sites

It is a cute concept, but highly inefficient, creates more toxic waste, does not solve the toxic waste problem, and does not solve the #1 problem, Idiots in Hollywood have twisted nuclear discussion so far into idiocy land no one can even have a logical discussion about traditional nuclear due to the decades of blatant lies spewed. You first have to wade through the lies before talking actual KWh, engineering etc. Only way to do nuclear in future is to go with a liquid fuel which gets rid of all the decades of lies surrounding traditional nuclear BS. Liquid fuel cannot, as far as I know, be done in a modular small way(probably can it is a liquid and should be easier to handle chemically) but does resolve nearly all the problems while at the same time makes thermal runaway impossible. 1 Quote Share this post Link to post Share on other sites

NickW + 2,714 NW February 4, 2020 On potential benefit of SMR's is that they are more appropriate to apply in situations where the waste heat can be used in district heating, desalination or glass house agriculture. The hot water output from a SMR will be about 800MW as opposed to about 3000MW from an EPR. Two SMR's with their refuelling cycle staggered can provide year round heat even if one reactor down. Also 3GW of heat is a huge of heat to utilise and most, in the absence of a huge desal scheme will go to waste. Quote Share this post Link to post Share on other sites
