U.S. Bets on Small Nuclear Reactors to Help Fix a Huge Climate Problem

The dream of reviving nuclear power in the U.S. rests on a new generation of smaller reactors meant to be easier to build. But major obstacles loom.

U.S. Bets on Small Nuclear Reactors to Help Fix a Huge Climate Problem

In a major setback last week, the first serious effort to build small reactors in the United States was abruptly canceled amid soaring costs. While other projects are still moving forward, the industry has consistently struggled to build plants on time and on budget.

“costs too much. gonna have to die from climate change instead”

Or...go ahead and build out a lot more solar, wind, and storage at lower cost

Even that isn't enough.

We still need to ruthlessly end North American car dependency...and reduce beef consumption...and stop fast fashion...and stop planned obsolescence and throw away crap

So…stop kapitalism? What are you? Communist?

I consider myself a hybrid. Some things, a market just doesn't work, like infrastructure and medicine.

Some things, like entertainment, restaurants, etc, REGULATED markets are best. Regulations are vital though. Costs can't be externalized. No bailouts. Your business goes under, tough.

what if you're too big to fail though? surely captains of industry would be bailed out like always

neanderthal

Then you get nationalized or broken up like ma bell.

then your “bailout” isn’t a bailout but a buyout by the public sector, and then probably split up and sold in parts to recoup whatever money they can and make sure it’s not too big to fail in the future

This is usually considered a Social Democrat. Or a Marxist. Using the government to limit the worst effects of capitalism. I especially love the idea that business can fail, something fought very hard for under capitalism - because capital never wants to lose.

I am.

I’d take that too.

Wind and Solar have limitations that Nuclear does not.

SMRs have advantages over traditional Nuclear.

The current problem is that they don't yet have the economies of scale to compete in the "free market". This ignores that there is not actually a free market when it comes to energy. Solar, Wind, Coal, and Oil all get subsidized at rates that Nuclear never sees.

There was a big effort to get nuclear to have a learning-by-doing and scale up. In the US at least, it largely failed leaving an industry incapable of competing on cost

The larger part of it is that in the 70s there was a concentrated effort by both the extreme environmentalists and the oil lobby to hamstring nuclear. The effects have been felt somewhat worldwide.

That's when the US subsidies were massively cut back and regulations put in that started to balloon costs for new plants.

Then Three-Mile-island happened, and the groundwork was already in place to tighten the belt even further.

To address your point a bit. Solar and Wind had large parts of the development cost handled by government grants, and then instillation costs as well.

All energy gets subsidies. Nuclear gets far less than anyone else, and yet has regulations that actually add costs. Hell, operating plants need to pay yearly licensing fees that are not cheap.

The red tape and regulatory morass makes even starting a nuclear project thousands of times harder than starting a solar or wind farm.

You have to have a full build plan submitted before you're even allowed to do a site survey. You then have to pay roughly $300 an hour for that plan to be reviewed. Then, when the plan is denied, you have to do the entire plan again, and you still haven't done a site survey.

Once the plan is approved, you do your site survey. You'll have to adjust the plan based on conditions at the site. This will usually be minor changes. Moving some things around, reinforcing a foundation due to the soil conditions. Stuff that every build project goes through. Only now your plan doesn't match the approved version, so you have to stop and resubmit at another $300 an hour.

So, building a plant takes a long time, if any regulation changes during that build time, you have to change your plan to meet the new regs, but now your plan doesn't match the approved version, so you have to stop and get it re-approved at $300 an hour. Then you have to tear out any parts that don't match the regs and rebuild them.

All of this is added to the fact that yes, most (American) nuclear plants are basically prototypes, in that they are custom designs, and most of their parts need to be special ordered. This adds immense cost.

SMRs kind of sidestep both issues. You get one reactor plan approved, it's a self-contained unit that's shipped to the site.

They're also all identical, and can be built in bulk. You can have supply chains for the parts to drive costs down further.

The main stumbling block are the first dozen or so reactors. Building up the factories to build the reactors is going to be costly.

Russia has the VVER series, which is standardized and built in higher numbers by relativly cheap Russian workers. Hard to say they sell extremly well abroad.

South Korea has hte APR-1400 which is build in somewhat higher numbers as well. However sales are still limited to basicly the UAE and the oney built in Korea.

At the same time you have massive construction of renewables in developing countries today. Those are countries which have a hard time handing over subsidies.

it's strange that we have money to subsidize aviation fuel, motor vehicle production/use, natural gas extraction, funding wars in foreign land, etc

but we don't have money for this

it's just strange

MrMakabar

•

It is producing electricity just like solar and wind turbines. Both of which are profitable today. So it would be smarter to use government money for some green projects without a viable cheaper alternative. That is also happening on a fairly large scale.

lntl

I think you missed the point, why's cheaper even a thing?

MrMakabar

•

The green transition is the biggest transformation of the worlds energy system in human history. We have to replace huge parts of the electricity system, transportation, materials with stuff like plastics, heating of our homes and change the food system across the world.

Obviously parts of that stand, but emissions are still going up, so we are clearly not doing enough. So we need to put more resources into it and we have to do it in a smarter way. We are nearly at a collapse situation, so especially rich countries have to think about shrinking the economy to not emit as much anymore. Wasting time and resources is just not a thing we have the luxury of today.

there's this idea that we have to be frugal and fiscally conservative when addressing the climate. when it comes to subsidizing war, fossil fuels, and motor vehicle use a different argument applies.

that's the point.

we don't need to be fiscally conservative with respect to the atmosphere. it's too important

Germany: "WHAT??"

silence7

The headline kind of buries the lede, which is that they're coming in at such high prices that none are actually getting built

chaogomu

That's the problem. SMRs will be essential in fighting climate change, but as has been said before;

You cannot fix problems caused by capitalism with more capitalism.

lntl

•

yeah, but couldn't we use capitalism to get out of this mess? it's guaranteed to turn a profit ya know

lntl

they should be subsidized to cover high cost
