Rolls-Royce SMR is an independent company backed by the UK Government, global investors and an international nuclear operator.
Our unique ‘factory-built’ approach is the fastest and cheapest way to get new nuclear on the grid - helping meet global net zero ambitions, increase energy security, and further reduce the UK’s reliance on imported hydrocarbons.

@@SA-xf1eb There are already a handful of net zero countries - existing in the current insane economy so it's already possible without nukes. It's just a matter of changing things and minds. We could get by without wars, armies, meat, advertising, two cars, pets, fashion, Christmas, holiday homes, International sport circuses such as F1, Cricket, Football, Rugby, Olympics, WRC, Golf etc. 200 streaming services, nail bars, 6-lane motorways, 2 foreign flights per year, just-in-time delivery etc. We could waste less food, eat less food, change phones less often, fix more stuff, pay people to stay at home instead of going out to sell cigarettes and fizzy diet drinks, or the next big thing. If we don't do a least some of these changes we'll probably lose it all fairly soon anyway.

@johnhunter4181 2. Only 2 and neither have significant economies. Large economies can only approach low-carbon net by swapping the base electric production to nuclear energy. Hydro hurts wildlife. Wind is not sustainable. Solar is unreliable and suitable for supplementing the base load. You are lying to yourself that just "changing mindsets" and eating crickets is how we save the world.

RR are ready to build Small Modular Reactors across the British isles. And they are ahead of the competition with a head start in development. And yet, time and time again the U.K. government is dillydallying about giving them the go ahead or giving it to hitachi or some other foreign firm. It’s time the british government supported british manufacturers for once.

SMRs unless they are based on molten salt still face challenges with radioactive waste, low fuel efficiency, and the risks associated with high-pressure reactor vessels. While SMRs can serve as a short-term solution, Molten Salt Reactors (MSRs) are considered a more promising mid-term solution due to their potential to address these issues more comprehensively. Hopefully, we will have fusion by the time we run out of uranium and thorium. The differences between Light Water Reactors (LWR) and Thorium Molten Salt Reactors (TMSR) are significant in fuel utilization and waste production. LWRs use approximately 0.5-1% of uranium fuel, leading to the generation of long-lived radioactive waste due to inefficient energy conversion and the use of enriched uranium. In contrast, TMSRs can achieve fuel efficiency of up to 99%. This is achieved by converting fertile thorium-232 into fissile uranium-233, substantially reducing waste production and more manageable radioactive waste. Uranium Molten Salt Reactors (UMSR) are just as effective as TMSRs. 800 kg of natural thorium in a Molten Salt Reactor (MSR) can generate 1 gigawatt (GW) of electricity for one year. In comparison, generating the same amount of energy in an LWR would require mining 250 tons of uranium. In an MSR, the storage requirement for 800 kg of spent fuel is 300 years, whereas in a LWR, 35 tons of spent fuel need storage for 300,000 years. MSRs can utilize the spent fuel from LWRs. A coal power station will need to burn 4.55 million tons of coal and emit 13 million tons of carbon dioxide to produce the same amount of energy for one year. That amount of coal contains 4 to 18 tons of uranium, 13 to 68 tons of thorium, and 4 to 45 tons of arsenic. Of the six proposed fourth-generation nuclear reactor types, the MSR is the only type that does not generate substantial amounts of plutonium. The fissile uranium-233 produced by the MSR is difficult to use for weapons because of the presence of highly radioactive uranium-232. MSRs can adjust power output to match electricity demand, thanks to the inherent and automatic load-following capability provided by the fluid nature of the molten salt coolant. A key safety feature of MSR is that it automatically adjusts to prevent overheating. This is achieved through a "negative thermal reactivity coefficient," which means that as the temperature rises, the reactor's reactivity decreases, preventing a runaway chain reaction. Additionally, the MSR has a "negative void reactivity coefficient," ensuring that the reactivity decreases if there is a loss of coolant or boiling, preventing potential overheating. These safety measures help keep the reactor stable and safe under various conditions. Looking ahead to 2040, China plans to deploy Molten Salt Reactors (MSRs) for desalination of seawater, hydrogen production, powering of ships equipped with Thermoacoustic Stirling Generators, and power plants with Supercritical Carbon Dioxide Turbines within its borders and globally. In the Earth's crust, thorium is nearly four times more abundant than uranium. Every atom of natural thorium can be harnessed, unlike natural uranium, where only 1 out of every 139 atoms can be used. China produces thorium as a byproduct of its rare earth processing. Similar to the trends observed with solar and wind technologies, MSR costs are anticipated to decrease with the scaling up of production and the development of robust supply chains.

While definitely modular, this reactor is technically not small. A reactor’s power output needs to be under 300MWe to be classified as small but this reactor’s power output is 470MWe. From what I understand Rolls Royce choose this power output because it’s the maximum power they could get from a pressure vessel that could still be transported by road in one piece.

The four nuclear SMRs that are competing for the UK government largess/competition are either small PWR (Pressurised Water Reactor same as Hinkley Pointless C) 3No. or BWR (Boiling Water Reactor) 1No. - too late, too little, too dangerous - SMRs require an advanced industrial infrastructure that is inherently fragile (the world is not moving to a nice place courtesy of Global Warming) - it will take 15 to 20 years to start to produce in numbers by which time renewables will be in place and global warming catastrophy unless renewables built at speed - the new designs can flex to an extent but because they will be low in number / MWs and the high capital cost means that they should maximise run time to pay back the cost - renewables are cheaper and scale, see Tony Seba - nuclear SMR dont scale well as the balance of plant is costly ie. steam turbines are cheaper when larger - a high renewables grid does not need base-load, it needs quick reacting infill eg you could use existing CCGT / OCGT/ engines for less than 5% of time with offset carbon capture - base-load is a myth : even intermittent renewables will work, see Diesendorf - SMRs are a terrorist / war target / dirty bomb in an industrial estate near you - none are designed to remain intact after a large plane crash - still no safe depository for long life nuclear waste which the public will have to fund - when refueling, air is polluted with nuclear waste (very low dose but measurement does not include exposure by ingestion of particles) - none of the competition SMRs are new designs or new fuel systems which in any case would need years to build out - they are uninsurable, the government will have to pay the cost of an accident - nuclear fuel reprocessing is costly, dangerous and polluting - access to uranium for fuel is limited (unfriendly countries, native land-rights,...) and diminishing in concentrations - they are great at using up money for scientists, reports, engineers... see also Small Nuclear Reactors Have A Big Problem Sabine Hossenfelder

why not use just abandoned mines?... they have the electric infraestructure ready to use, also have minning quality roads, you can place inside the modular reactors keeping them allready buried in case of emergency as also a place to keep the waste, also could have underground pools with no escapes for evaporation losses... it could be operated remotely in case of earthquakes... it could save a lot of costs, and there are plenty of closed mines near some cities.

What about the fluid dynamics? Reactors are more efficient the larger the pipe diameters for fluid dynamics. Site costs for security, approvals, social engineering etc. Most of the expenses with low output. It seems more like a Silicon valley glossy brochured investment scheme rather than a practical solution. Interested in your feedback. It seems like a fundamental engineering limitation.

there has never been economies of SMALL scale in electrical generation. SMRs will cost significantly more per Mw generated than the current 1Gw standard. And the main thing holding back all new nuclear is the cost so increasing that is really not a good idea

A small modular power plant the size of two football fields. Power capacity 420 MwH . Not worth having. that means you need 4 of those reactors to get 1 GwH of power. Which is what a coal power station puts out. You would have to have on of those every 10 km's up the rd.
