#small modular reactors

[jellysshitpoems]

What’s your opinion on small nuclear reactors/SMRs? I’ve heard a lot about them recently (including some advertisements actually) but I’m not sure how applicable they would be outside of their current uses, like powering naval ships/icebreakers and research stations. I’ve read that they could be used to power off-grid native communities; is that something that gets discussed a lot in Canada?

As always, I hope you’re doing alright!

You just managed to touch on two things rarely talked about in Canada, Indigenous communities that are in need of help, and SMRs 😅

Small modular reactors aren’t something Im particularly well versed in, I wasn’t even aware they were used on/considering using them on large ships, but it makes sense! I heard that they could be used to power things like natural disaster clean up, due to their portability and what not, but using them to power remote communities (Indigenous or not) Is a great idea!

Unfortunately though, Canada doesn’t exactly have the greatest history with helping said communities. In fact theres a lot (and I mean a fucking LOT, over 600) of reserves that don’t have access to even just clean drinking water. Hell I did a whole project on a community that has had mercury poisoning for decades! And their levels are still so high it can affect fetal development! So I doubt any reservations or towns are getting billion dollar SMRs- Thanks Canadian government!!!

I feel like I always find a way to derail these asks. Oops.

Anywaysss, from what Ive heard SMRs are super cool, I just dont know a lot! My brain has bigger fish to fry when it comes to my hyper fixation if that makes sense lmao, I like big reactors and huge facilities. Organization and protocols and precautions kick my adhd into gear, yayy systems 😁😁

Amundsen-Scott South Pole Station undoubtedly has many useful lessons for any lunar or planetary outpost. But we have to take a moment to stand aghast at the energy supply.

“Hundreds of thousands of gallons” of a super-expensive specialty grade of jet fuel, brought in either by air, or by driving tractors and sleds for “several weeks” across the ice cap?

A nuclear power unit for an electrical load of about 1 MW (and a corresponding heat load of about 3 MW) would be very costly. No doubt about it. But could it be that costly? Equally to the point, with a refuelling interval of not less than three years, worries about laying up enough fuel in before winter closes in would be a thing of the past, even considering the needs for aircraft refuelling and backup fuel in case of a reactor problem. Simply endangering fewer lives on hazardous supply flights and traverses would justify the cost.

The unsatisfactory performance of PM-3A at McMurdo has given atomic power an undeserved bad reputation in the polar regions. Yes, we say undeserved — certainly, leaks from the primary circuit resulted in contamination, with the result that a large volume of gravel from around the plant was dug up and shipped back to the USA as “nuclear waste”. But contamination by petroleum fuel is far more common, far more extensive, and far more difficult to detect with cheap hand-held instruments.

Shower thoughts on power generation

Starting assumptions:

The current generation of Small Modular Reactors has never been small enough to containerize, but there are small thermoelectric containerizable power plants without proliferation concerns: see the Mars rovers

Gigascale nuclear is still cheaper per MWh than SMR

But solar and wind are cheaper than gigascale nuclear

But solar and wind aren't 100% availability

Batteries are somewhat expensive

Flywheels are already containerized (see Kodiak, Alaska)

Terraform Industries would be stupid if their plants weren't containerized, and they don't seem stupid. Their rollout starts in 2024.

Carbon-neutral and carbon-negative don't mean "no carbon-based fuels"; just "no fossil fuels".

How do I see the near future playing out, say by 2050?

Containerized nuclear thermoelectric batteries are used for low-load low-sunlight high-impact postings, as a form of set-and-forget critical infrastructure. This is the most-wishful item on my list.

Maybe there's some geothermal in the mix, but it remains high cost to site and construct relative to other forms of power, and has limited geographic availability.

Gigascale nuclear gets built when your consumption density is higher than available solar/wind generation density, so long as it remains infeasible to build new long-distance power transmission lines.

Solar/wind fields power containerized electricity-to-CH4 plants as a source of carbon for carboniferous fuels. This fuels non-electrified mobile sources and, directly fuels demand-responsive gas turbines for The Grid when the sun don't shine/the wind don't blow. Your renewables overproduce electricity, beyond what The Grid needs? Make CH4. Don't want to deal with permitting for a thousand-mile-long transmission pipeline? Don't. Colocate CH4 generation with CH4 use.

Need a microgrid for a Burning Man, a FEMA camp, or Palestine? Unload a containerized 1MWh solar/flywheel/battery/CH4 setup, with 5 acres' worth of containerized solar panels to back it up. Knock out the temporary panels on the containers and convert them to modular buildings. Need more MWh? More containers, more acres. Or just truck in a couple tankers of methane and a generator.

Applications requiring high energy density switch to CH4, or use the cheapest solar/wind electricity to turn CH4 to propane/kerosene/gasoline as needed. Aircraft and many ground vehicles will still emit CO2, but it's CO2 that was sucked from the sky: Net Zero is achieved.

Net CO2 reduction comes from diverting air-sourced carbon to fixation: plastics, paints, asphalt, concrete, diamonds.

The Haber-Bosch process uses air-sourced hydrogen or desalination-sourced hydrogen instead of fossil hydrogen to make ammonia.

"MUMBAI: State-run Indian Oil Corporation Ltd is in preliminary talks with atomic power monopoly to build small nuclear units [Small modular reactors (SMRs)], an early-stage technology seen as a cost-effective alternative to larger plants.

The refiner and fuel retailer is exploring a partnership with state-controlled Nuclear Power Corporation of India Ltd to use small modular reactors, or SMRs, in its refineries for clean power, Alok Sharma, Indian Oil's director for R&D, said at a conference in New Delhi Wednesday.

As several bigger projects face delays, policymakers are promoting small-scale nuclear technology with a capacity of up to 300 MW, which is quicker to build and easier to adjust to the requirements of the grid. To boost the nascent sector, the government is considering allowing private firms to manage and operate reactors."

Ghana 🇬🇭 Nuclear Deal: Small Modular Reactors From Five Potential Suitors

Ghana 🇬🇭 has been experiencing energy growing pains as of late, & the nation is actively seeking out nuclear power as a long-term option.

Fortunately, the nation known for its gold has a golden opportunity to have a nuclear power plant built within its borders & is actively being courted by five nuclear-powered nations.

“Choosing the US industry offers advantages you can’t get from anyone else,” said Maria Korsnick, president of the US Nuclear Energy Institute. “The US industry will not seek to weaponise energy production or trap partners in a cycle of debts. We want real partnerships that lead to real energy independence and security.” […]

Ahead of the summit, the US government committed $1.7m to the development of a Small Modular Reactors (SMR) simulator in Ghana to serve the region, matching up similar efforts by Russia’s state-run Rosatom that only recently sealed a nuclear power plant deal with neighbouring Burkina Faso.

Since 2021, when it put out a request for a vendor country, the West African country has received proposals from the US, Russia, China, France and South Korea.

Although the government of Ghana 🇬🇭 still has friendly relations with France 🇫🇷 & Russia 🇷🇺, it would be surprising for them to pick either of those countries due to the growing anti-France sentiment in Africa & global sanctions on Russia 🇷🇺 (over their invasion of Ukraine 🇺🇦), respectively.

China 🇨🇳, South Korea 🇰🇷 & the United States 🇺🇸 are probably the leading contenders for a reactor, with the latter being the most welcoming due to availability of capital.

Hopefully, more African nations will be courted with nuclear energy deals in the future, as Ghana’s 🇬🇭 bigger brother Nigeria 🇳🇬 is also in desperate need of a nuclear power plant.
