Re: SMRs are expected to produce 300MWe per unit.
How about a discount on your heating and electicity? I'd suggest based on an inverse square relation to distance of your residence from from the plant. Could apply this to wind turbines and such, too. Why not give people a cash-in-hand incentive rather than the usual vacuous promises about jobs and sustainability?

Re: district heating
An excellent proposal. Still, the only way NIMBY can be overcome when it comes to nuclear power is if that district sets aside a rather large buffer zone for the SMR in case of emergency. This relegates SMR-heated districting to edge-rural locations, but that can still work if other factors are considered (transportation and other functional infrastructure).
It does have echos of [the eventual finale of] Pripyat however...

Re: Money for old rope
Scotland is almost completely self sufficient for green energy
Only when you fiddle the figures, as Sturgeon & the SNP propaganda does.
That statement is based on the idea that (in 2020) Scotland produced 32TWh of renewable electricity, and consumed 33TWh of electricity and therefore "almost all Scotland's electricity comes from renewables". In reality, renewable energy production is dependent on weather, and the supply/demand periods don't align.
In 2020, Scotland exported over 13TWh of renewable electricity at some times, and used over 14TWh of non-renewable at other times. Over the course of a year only about 55% of Scotland's electricity comes from Scottish renewables (the remaining 45% is from nuclear, gas & oil), a far cry from "self-sufficient".

Re: Money for old rope
I think you need some remedial arithmetic lessons. There's little difference in quantity between 32 and 33.
Your numbers say Scotland produced 32TWh of renewable electricity and consumed 33TWh of electricity in 2020. So supply and demand are almost equal. In other words, total renewable electricity generation in Scotland pretty much matches the nation's total electricity consumption.
It's true the supply and demand periods don't always align. This is no big deal. Power companies deal with this all the time. It's a basic principle of the electricity business: you supply me with your extra power when I need it and I'll reciprocate when I've got extra that you need.

Re: Money for old rope
@LybsterRoy
Its not all about "windmills" - about 1/5 of the Scottish renewables from hydro on lots of rivers, each one not generating a huge amount (a few mega Watts) , but will always be generating power (bar mechanical breakdown) so a "reliable" renewable compared to wind, solar etc.
We will always have a few days of low/no wind in the UK so wind alone will never be a panacea, so a good mix of renewables is vital.
As for nuclear, I don't think that many people are thinking "mushroom cloud imminent", more likely to be concerned about risk of local "leaks" and the issue of what happens to all the waste long term as that's the issue that keeps getting kicked into the long grass. The botched cover ups / lack of honesty about nuclear incidents in the UK has been counter productive, fessing up to fuckups would have been better, the whole lie to the public stance actively encouraged more distrust of nuclear IMHO.
Ironically I grew up in a mining area and back then virtually all the homes were heated by coal (until it was made a smokeless zone) - and so would have been exposed to more radioactivity from coal combustion than if I lived near a reactor (especially as I often got the job of clearing the ash from the grate and throwing it in the bin, where the radioactive residues would be nicely concentrated)

Germany already has this problem. It is "handled" by depending on France, Poland, Czech Republic, Austria and Switzerland to supply and consume large amounts of electricity to/from Germany.
In other words, wind+solar need 100% backup in the form of coal, methane, Uranium, Plutonium (the Russians currently burn some of that) and Thorium.

Good point here. China actually built an interesting transfer policy around it. Simply said, China doesn't allow dumb manufacturing for foreigners anymore, nor does it allow "dumb" installations on its soil by foreign compaies. Ten years ago, Daimler would build their own factory in China, just like they do in Mexico or Spain, German companies would design, build and commission the factory, locals would be allowed in as workers. Not anymore. Everything must be done in partnership with local companies, including design and equipment sourcing. It happened quite recently for general public to notice in full, but one already sees local jet airliners supplementing the huge fleets of Boeings and Airbuses, and, to the point, nuclear power plants being built by local consortia with technology and knowledge transfer being an important part of the deals.

One reason (amongst many) is alluded to in the article:
"prefabricated units of SMRs can be manufactured and then shipped and installed on-site, making them more affordable to build than large power reactors, which are often custom-designed for a particular location, sometimes leading to construction delays.
Even though a series of reactors may be built to "Reactor Type X" plan, each individual reactor is essentially custom hand-built on site. As well as the expense in hand-building these things, since they are each effectively a custom unit, each one has to be certified separately that it is actually built to the common plan for Type X, and that any deviations are verified, and so on. This makes them incredibly expensive individually, as you need skilled (nuclear reactor skilled) workers on site, custom fabrications, running into unexpected issues which leads to delays which means more costs, the potential for cost blowouts goes on and on. Big-bang custom software project billion-dollar blowouts have nothing on nuclear reactor delays and blowouts.So instead of hand-building a custom 3600MW reactor on site, the idea is to mass-produce smaller reactors, so you can plonk 12 of these mass-produced, identical, needing only quality-control-type testing/certification that any mass-produced but complex machine is, down on the same site to create your 3600MW plant. And since you have 12 of them, they can be independantly controlled, maintained, refueled/replaced without taking down the entire 3500MW reactor. They can also be expanded or decommissioned more gradually. Add another 300MW reactor if want to make the site provide more power, take them out one-by-one to decommission them. Build smaller sites so you don't need a single 3600MW plant. Able to ship them to remote sites (e.g. Shetlands, Fiji, middle of Amazon) to establish smaller, local power infrastructure without having to run submarine/overland transmission infrastructure, etc.
If you are going to go nuclear for low-emissions power (as opposed to solar/wind/hydro/geothermal etc.) then SMRs seem a better way to do it.

Economics of Reactor R&D
210 Million Pounds are a tiny amount of money compared to what is wasted on r0tten bankers, illegal wars and dangerous medical schemes.
Also, just adapting a uboat reactor to civilian use will cost more than 210 millions. All of the technology must be tested, certified, reviewed and at least one protoype must be run for three years or so.
Developing a new car model costs several billion euros these days. Based on evolving a previous car model. The safety and political implications of a rott3n car model are much smaller than a r0tt3n reactor model.
Due to the strategic nature of energy supply and the lack of national methane supplies in many European nations, governments must step in and provide the necessary funding and organization, Airbus-style. The alternative is to be dependent on foreign powers who might be friendly or not. Some of these powers can point dangerous weapons and armies of soldiers at you, all while supplying critical methane.

Currently any civil nuclear new build is, as a matter of government policy, to be constructed on an existing nuclear licenced site (e.g. Wylfa). Since one idea behind factory built SMRs was that they can be shipped ready fuelled (which has been proposed in the past for civil and military cores) then the factory will require a Site Licence. I can't see that happening. For Site Licencing details see https://www.onr.org.uk/licensing.htm.
As to the practicality of producing SMRs that will actually meet ONR requirements - there is no size based approach to reactor safety - a 300 MW(e) SMR will not necessarily be 1/10 the size and complexity of a 3000 MW(e) EPR. And the submarine reactors are not actually operating at full capacity in inshore waters.
There is a public aversion to living next to a nuclear power station, so district heating, or tomato growing, is not really going to work. The SMR sites shown in the centre of Legoland towns is a bit of a pipe dream.
By the way, the UK is not worse at building reactors. EdF is a French state controlled entity which has yet to finish the first of a kind EPR at Flammanville. The UK detailed design of the EPR for HPC means it has to be built to different (i.e UK) standards. The construction of HPC is continuing on schedule, but fuel load keeps going back as Flammanville recedes. Okiluoto has just gone critical (and look at the delays and legal actions on that). The recent French government intervention in the EdF finances, and EdF's attention becoming focused on EPR2 might will have an impact on Flammanville schedule.

Yeah, MSR
The latest snake oil by American Oligarchs. Totally fully safe, no problem. If you believe one Oligarch who never bothered to get a proper scientific education. Or any other professional education. He is not even a certified accountant.
Here is the protip: Nuclear fission fuel of ANY type will have something called NachZerfallsWärme of about 10% of operational fission power for days. Then for weeks something like 1%.
So a 3000MWth reactor will have a cooling need of 300MWth for several hours after emergency shutdown. thats 300 000 000 Watts of power. You better have a nice water flow for cooling. The big problem of the Japanese was that they could not repair or replace the cooling. So they had nasty stuff such as core melting and hydrogen generation, plus a nice hydrogen explosion. Whoever has an education can imagine that and reactors usually have redundant water flows.
Having said that, I am a proponent of nuclear power for economic, strategic and environmental reasons. But don't let yourself be fooled into the idea that there exist totally idiotproof reactors. Read up on Rickover to get the details of proper reactor operations.

Re: Yeah, MSR
"The big problem of the Japanese was that they could not repair or replace the cooling."
Jim Al-kahlili did a special on Fukushima and it seems that a major problem turned out to be human. Go figure. The operators were under the impression that they couldn't leave the passive cooling system on for an extended period of time and were cycling it on and off. When the backup power finally failed, the system was in the off position and they didn't know because they had never tested it. Plan D failed when they didn't know that a valve would divert emergency cooling water pumped in from fire engines to the base of the cooling towers rather than into the reactor. Again, never tested. The reactors scrammed when the earthquake hit and the worst peak in reactor temperature had passed, when the tsunami hit, they were managing decay heat at that point. The people problem was compounded by fundamental design flaws in the site layout. The backup generators and battery system were placed below grade and subject to flood damage. Not very bright as tsunamis are not unheard of in Japan.

Put one of these in the Drax power station and stop burning fake renewables, biomass and wood chip. Because these are so small, it is possible to put more than one in a power plant, which is also good from a service perspective, because you can shut one down at a time without losing all the power. So these can go into the newly closed down sites such as Wylfa and Hunterston. This is a good quick, zero CO2, renewable, sustainable, safe way to produce low cost electricity, reduce CO2, solve climate change and create UK jobs. Next step export them to replace coal and gas power stations in Africa and Asia. Good to put them in existing nuclear, biomass, coal, gas power stations because you do not need to build new expensive transmission lines.

Honest Accounting
Nuclear is not zero CO2. Neither is wind or solar. Both need ENORMOUS input of coal to produce the concrete, steel and the cells themselves. And the elements to make the cells.
It is called EROI - energy return on investment.
EROI = EnergyProduced / (EnergyForMachine + EnergySpentForFuel)
Nuclear EROI is at 80, solar cells at 10, windmills at 20.
Even hydropower emits CO2, because dams or "bathtubs in the sea" need voracious amounts of concrete and steel to build. Concrete and steel are made from large amounts of coal. The coal can NOT be replaced in a large scale for the time being.
Here is an attempt at designing a Bathtub to store the fluctuating German wind+solar power for just one month:
https://fgw.ddnss.de/StromSpeicher.html
It would require the concrete production of all of Germany for one year, but it might nevertheless make sense to build it, as it is highly efficient compared to hydrogen storage.
Hydrogen storage loses something like 60% of power in the storage+retrieval cycle. Water storage loses just 10%.

Bring out the dead, er lawyers
Sure, let's multiply one lawsuit by 10 and hire an office block full of lawyers at an average of £500/hr each to answer all of the suits. Don't forget that there will be protests against the pylons that will have to go in to move the power from each plant, so more lawsuits. People that will put their cell phone to their head for 14hours/day will scream bloody murder about their health if there are high tension lines near their home or work. One child born with a defect will generate yet another lawsuit that may be cheaper to settle than litigate.
While nuclear power plants aren't cheap to construct, there is a huge amount of money that has to go into all of the lawsuits, planning, land corridors for power lines, inspections, rework, delays, etc that aren't the plant itself. These costs don't vary that much with the size of the plant. The power lines are bigger, but the pylon price doesn't scale at the same rate. The land stays the same, stuff like that.
I agree with the concept of not putting all of ones eggs in one basket, but it's not a law. There is no economy of scale building nuclear plants in a factory vs on-site. There just isn't enough volume to make the case. They are sort of constructed off-site anyway and assembled at the location unless something needs to be fitted custom. If something like a LFTR plant becomes reality, those lend themselves to off-site modular construction.
And another thing, what B-Ark advertising executive came up with the idea of shipping a reactor fully fueled? Any sane engineer would want to have the reactor installed at its location and fully tested before going hot. The safety protocols are much simpler without the fuel in-situ. It also means that pressure, electrical and sensor checks can be more completely tested after installation to catch any damage that occurred during shipment. Mass would also be an issue. When in California on one visit I came across a shipment of spent fuel being moved from the San Onofre power plant. The casket was cradled on a 192-wheel trailer with 2 trucks pulling and one pushing. They had stopped for the day as they only moved at night due to traffic issues. I have a 5 photo panorama of the rig. This was just fuel rods packed up safe and sound. The rest of a PWR doesn't seem like it would be moveable by road in one piece. This would infer that every small site would have to have a road system that could accommodate extremely heavy and oversize loads with no bridges. The trailer in California would not fit under standard bridges and the weight would be too much to go over many.
