President Trump signed four (!) executive orders to make the U.S. the world’s leader in nuclear electricity.

Some of it is promising. Some of it might backfire. Let’s break it down.

Nuclear Executive Orders megathread ☢️
Starting with the juiciest EO of them all: Reforming the NRC!

If you’ve been in pro-tech spaces on X, you’ve heard that the Nuclear Regulatory Commission is to blame for nuclear’s abysmal performance in America in the past 30+ years.

“Since 1978, the Nuclear Regulatory Commission (NRC) has authorized only five new reactors, and of these, only two have been built,” reads the EO.
Ignore the fact that the NRC has actually licensed 14 new reactors since 1978, though only 4 began construction and a measly 2 finished.

The truth is that the aftermath of the oil shock in the 1970’s had a lot to do with reactor’s orders disappearing:

- Interest rates were super high. 

- Load growth slowed down a lot.

- Productivity at construction sites went down (partly because after Three Mile Island regulations were changing in real time.) 

To learn more about this, pre-order my book Rad Future. Yes, this is a shameless book plug.

But whatever, I’m not here to defend the NRC.
It’s important to point out that the NRC has approved 3 never-before-built test reactors in the last 18 months:

- Kairos Hermes 1 & 2 (salt-cooled, TRISO-fueled)

- Natura at the Abilene Christian University (molten salt research reactor)

They are also considering permit applications for Terrapower, BWRX-300 and X-energy.

That said, the process is still far too slow. 

The NRC could be be less like the DMV and more like a team of Zynned up Gundo guys.
There are also some truly dumb regulations out there. 

For example: did you know that to build a nuclear reactor, you need to put up a 197 foot high meteorological tower in the chosen location to gather a year worth of wind data and submit it to the NRC? 

When you could just… wait for it… get that info from NOAA. 

There are thousands of little things like this driving up costs and timelines.
My biggest concern is that the EO gives somewhat vague marching orders and unrealistic timelines, potentially sending the NRC into a bureaucratic tailspin.

I am hoping those involved know exactly what regulations can be updated or removed and have the adequate resources to do this major overhaul.
If I had a magic wand, this is what I would add to the Executive Order: 

•Focus less on a deadline and more on licensing new reactors in batches through joint environmental impact reviews.

•Cross agency coordination between the DOE, DOD and NRC.

•Require new base appropriations to support streamlined NRC processes instead of cutting staff. 

•Add international coordination provisions (e.g., joint safety reviews, mutual recognition).

•Include explicit guidance on reactor nonproliferation and security in licensing priorities.
My most controversial take is that the NRC should only concern itself with technologies that are ready to be deployed.

Realistically, 90%+ of the 70+ nuclear startups will fail. That’s not shade, it’s just how innovation works.

The NRC shouldn’t burn its limited resources on designs that may never leave the lab.

In my ideal world, companies developing early-stage reactors would be allowed, through the DOE, to build and test their prototypes on federal land in remote, controlled environments.

Then, and only then, once they have a working prototype, they’d go to the NRC for licensing.

That process could be streamlined, too, because by that point, we’d know the thing actually works.
Which brings us to the next executive order: Reforming R&D through the DOE!

This is brilliant and exactly what we need! It: 

- Classifies advanced reactors as research reactors.

- Gives the DOE authority to approve small modular and microreactors.

- Expedites or eliminates nonessential environmental reviews.

What's missing is follow-through.

Building a prototype is the easy part. The hard part is building the first few, when the cost curve is still high to compete with natural gas plants or renewables.
If I could add to the EO I would:

•Create a broader build strategy to bring down costs and mature the supply chain.

•Aggregate demand through federal procurement: military, national labs, industrial hubs.

•Ensure repeat builds of the same design, not one-off science projects.
Next up: Reinvigorating the nuclear industrial base!

Among other things, this EO empowers the Department of Energy’s Loan Program Office (LPO) to support the: 

- Restart of closed nuclear plants.

- Increase of output at operating plants.

- Finish half-built reactors.

This is all low-hanging fruit. Do it.
But I’d go further: The LPO should help fund a few new builds to keep the pipeline moving, reduce costs, and show investors that nuclear can scale.

And the AP1000 should absolutely be part of this renaissance. We know it works and we know how to build it.
If I could sneak a couple of things in to help move from bespoke one-offs to repeatable, industrial builds:

•Set up a national buyer’s club.

•Mandate orderbooks for key designs.
Finally we have: Nuclear Energy for National Security!

This EO directs the DoD, in coordination with the Secretary of Energy, to identify 9 military facilities that can host nuclear reactors within 60 days. 

Great, love that for us.
Overall, the Executive Orders are a big step forward in helping unproven reactor designs get built.

That said, I’d like to see more emphasis on supporting the technologies we can scale right now.

At the same time, eliminating or even just downsizing the LPO, or decimating clean energy tax credits, would be a disaster.

It would make scaling any reactor technology, proven or not, nearly impossible. 

The first few units of any new design will be insanely expensive and almost certainly take longer than planned.

Private capital simply isn’t going to take on that kind of risk alone. 

Over the next 25 years the nuclear industry is a $7 - $10 trillion opportunity globally, let’s invest now so we can lead abroad!

Well, it seems like the latest draft of the EO includes exactly what I recommended.

The LPO shall support uprates and *10* new large reactor builds.

I don’t have any hot takes on the immigration controversy, but felt inspired to share my story.

Some of my most vivid childhood memories in Brazil are of watching American movies after getting home from school.

They were light movies like Bethoven, Paulie or Babe.

In hindsight there were a lot of talking animals.Image
Image

I loved the United States of America even then, before my developing brain could understand why.

Life simply appeared to be a lot better in America and everyone seemed happier.

I mean… people had air conditioning, laundry machines, dishwashers and TALKING PETS, how could they not be happier?!
For years I dreamt of moving to the US, as a deep part of my soul always knew it was my true home.

The opportunity finally presented itself when I was 18 years old and a modeling agency based in Miami invited me to spend a couple of months working there.

That was my chance and I jumped right on it.

My photo kissing a nuclear waste cask went viral and people had… opinions about it.

There was outrage, with many claiming it was dangerous and that I was hurting my future children (lol).

Here’s why kissing a nuclear waste cask is actually fine🧵
The waste people are concerned about and say remains dangerously radioactive forever is called “spent fuel.”

Contrary to popular belief, spent fuel doesn’t look like neon green slime. I know, shocker.

It looks exactly like the fuel that goes into the reactor in the first place:

Just a bunch of ceramic pellets, lined up inside very long metal rods that are bundled together.Image
Image
When fresh fuel goes into a reactor, it stays there for about 18 to 20 months making electricity.

After that, it becomes less efficient and needs to be replaced.

That’s when it becomes spent fuel.

The problem is that spent fuel is super radioactive and hot. We can’t just toss it anywhere, it needs to be managed safely.

So, what do we do with it?

how it started how it’s going
two years ago i called big pro-nuclear organizations to ask what they were doing to save diablo canyon. the responses were the same: “don’t waste your time, it’s a done deal.”

guess i’m a terrible listener, because i kept digging…
until i came across @ParisOrtizWines from @StandUp4Nuclear and @energybants. we started a weekly call with @Heather_mom4nuk and @kristinzaitz from @moms4nuclear who had been relentlessly working on saving diablo canyon since 2016.

TODAY IS THE DAY!

california legislature will decide on the future of diablo canyon. it’s obvious that keeping it open is the right thing to do to keep the lights on, reduce emissions and ensure california remains a climate leader. #SB846 Image
one objection to keeping it open was what people called a “solar tax”. the issue was fully cleared yesterday and the rooftop solar industry has removed its opposition to it. win win 🏆 Image
BUT WHAT ABOUT THE EARTHQUAKES?

don’t listen to me, listen to this expert of 50 (!) years in earthquake engineering and earthquake risk management:

CHERNOBYL UPDATE:

there’s been loss of some power at the chernobyl nuclear site. but how dangerous is that? by the year 2,000 all of the reactors at chernobyl power plant were shut down. so the risk of a core meltdown is ZERO
what about the risk of spent fuel in cooling pools? when the uranium pellets come out of the reactors, they still produce heat for years. that’s why they need to stay in a pool and be cooled down. they produce less and less heat as time goes by, reducing the need for cooling.
in most cases this fuel is cool enough to be transferred to dry casks (example below) after 5 years. the spent fuel in chernobyl has been chilling for over 20 years.

#Zaporizhzhya thread:

it is the biggest nuclear power plant in europe (6 reactors)

3 reactors were offline already

2 more were recently shut down

there seems to be 1 reactor still operating
a couple of hours ago, russian military attacked the plant and caused a fire in an administration building. the reactor buildings were not on fire and seem to be safe.
contrary to what some people are claiming, even in the worst case scenario, this would NOT be an event 10x worse than chernobyl. or even just as bad as chernobyl.
