Welcome to Nuclear Update! The newsletter that makes boring nuclear sector news Small, Modular, and Rib-tickling. (Sorry for thatācouldnāt come up with a better R word.) š
This is what I got for you this week:
šFirst Major U.S. Nuclear Buildout in 15 Years
š¤ÆTexas Files to Build 4x AP1000s
šŖTrump Plans More Executive Orders
šµHow Radiation Guards Billions
But First; This weekās trivia question:
š§ How hot is the coolant water in a typical pressurized water reactor (PWR) during normal operation? |
Last week, I asked: Chernobyl's infamous Reactor 4 melted down in 1986 ā but in what year did the last operating reactor at the site, Unit 3, officially shut down?
You said:
šØā¬ļøā¬ļøā¬ļøā¬ļøā¬ļø 1986 (7%)
šØā¬ļøā¬ļøā¬ļøā¬ļøā¬ļø 1987 (16%)
šØšØšØšØā¬ļøā¬ļø 1990 (31%)
š©š©š©š©š©š© 2000 (46%)
Now, letās dive into the good stuff!š„

šFirst Major U.S. Nuclear Buildout in 15 Years
For the first time in over 15 years, a new full-scale nuclear power plant is being publicly planned in the U.S. ā and itās happening in New York.
Governor Kathy Hochul just did a mic drop on Americaās clean energy future by announcing a 1 GW-scale plant in upstate NY.
Thatās enough juice to power a million homes (or keep 40,000 Manhattan espresso machines running nonstop.)
The project will be led by the New York Power Authority (NYPA), with the orders to: build clean, build fast, and build something that doesnāt break the grid (or the budget).
NYPA is working with Constellation Energy (the biggest U.S. nuclear operator) to explore sites, likely near one of its three existing NY plants ā with Nine Mile Point as the early frontrunner.
New York shut down Indian Point in 2021 (hello, emissions rebound). That left a big clean energy gap ā one renewables alone havenāt filled, and Trumpās May executive orders gave states new ammo to bypass the usual NRC slog.
New York is also looking north ā studying Ontarioās plan to build four SMRs ā and could even go modular if the economics line up. Hochul hinted it might be one big reactor, or a cluster of smaller ones.
š Why it matters:
Itās a test case for Trumpās nuclear permitting reforms
It signals a mainstream comeback for nuclear in blue states
And it shows how energy policy is shifting from scarcity to abundance
If this works, it wonāt just be about 1 GW. It could be the start of a nuclear domino effect in other states facing the same power crunch.
ā”TL;DR: New York is going nuclear again ā planning a 1 GW advanced reactor with public funding and Constellationās help. Itās the first major new U.S. nuclear build in over a decade, and a critical test of both Hochulās clean energy credibility and Trumpās regulatory overhaul.

š„ Oh, by the way. Nuclear Update Premium dropped on Saturday, and itās still free (for now).
The first edition is live and packed with:
Our uranium & nuclear portfolio (with buy/hold/watch signals)
Insider moves, market cycle heat checks, and sector sentiment
Deep-dive analysis from me and @TriangleInvestor
Weāre keeping it free just for the launch. Next week? Paywallās going up.

š¤ÆTexas Files to Build 4x AP1000s
Everythingās bigger in Texasāincluding the ambition to revive U.S. nuclear.
Rick Perryāa former Texas governor and U.S. energy secretaryāhas launched Fermi America, a Texas-based energy developer focused on pairing nuclear power with hyperscale AI infrastructure.
The company just filed plans to build four large-scale reactors.
Why? They want to power what would be the largest data center campus on Earth, to be named (unironically) the Donald J. Trump Advanced Energy and Intelligence Campus.
The plan: 4 AP1000 reactors delivering 4 GW of nuclear, plus 7 GW of natural gas backup, and 18 million square feet of hyperscale compute.
Oh, and each reactor would be named after the current president. Sure, perfect, no feedbackācarry on.
Fermi America is hoping to start construction in 2026, with the aim to have the full site online by 2032. Fermi says its remote location and Trump-era NRC reforms will help streamline approvals and speed things up.
Unlike New Yorkās state-backed clean grid effort, this is a private megaprojectādesigned to power massive data infrastructure, not public homes. And while it's further along in terms of filing (submitted to the NRC), itās not yet funded or approved.
It is however the largest private nuclear proposal in U.S. history aiming to reframe nuclear as a tool for tech dominance.

š„ Could I Drink Nuclear Reactor Water?
Finally the answer to the question we have all asked ourselves: is the water around the core of the nuclear reactor clean enough to drink? š

šTrump Plans More Executive Orders
As reported by Reuters, Trump is planning another batch of executive orders aimed at slashing permitting delays, fast-tracking grid connections, and offering federal land to build data centers in an āAI Action Planā, expected by July 23.
The moves are part of a broader strategy to dominate the AI arms race with China, but behind the tech headlines is a looming energy crunchāand another push towards nuclear.
The numbers are staggering: U.S. power demand is growing five times faster than expected just two years ago. And Deloitte says AI data center demand alone could rise 30x by 2035.
Back in January, Trump declared a national energy emergency, naming nuclearāalongside oil, gas, and coalāas essential to national security and AI competitiveness.
Now the upcoming July 23 āAI Action Planā could tie it all togetherāpairing advanced reactors with federal land, streamlined permits, and hyperscaler demand.
šļø U.S. Energy Secretary Chris Wright, went on the air last week to confirm that nuclear is āone of the administrationās top goals.ā
He also previewed nationwide permitting reform, efforts to cut project timelines from years to months, and new incentives for hyperscalers to bankroll nuclear builds through long-term power contracts.
āNuclear might be more expensive at first, but AI giants want it. Theyāll pay for it,ā he said.
Watch the full clip of Chris Wright breaking down nuclearās role in AI, national defense, and energy dominance.š

šµHow Radiation Guards Billions
Welcome back to Atomic Alternativesāwhere we explore the weird, wild, and wonderfully underrated ways nuclear tech shows up in everyday life.
This weekās spotlight: bank vaults.
Because when it comes to guarding billions, āgood enoughā just wonāt cut it. Enter: radiation-based intrusion sensors.
These vault systems often rely on gamma-ray or neutron-based detectors that act like invisible bodyguards for the vault walls. The principle? Radiographic density detection.
Hereās how it works:
Vault walls are constantly scanned with a low-level radiation beam emitted from a secure source (think sealed radioactive isotope or compact neutron generator).
On the other side, sensors measure the intensity of what gets through. If someone starts drilling, melting, or even messing with the structural integrity, the material density shiftsāand the radiation signature changes instantly.
Unlike basic vibration or motion sensors, these systems can see through thick concrete and metal, spotting microscopic changes that no camera or microphone could catch.
Theyāre so sensitive, they can detect things like internal corrosion, stress fractures⦠or, you know, an Oceanās Eleven-style heist in progress.
Itās also incredibly tamper-resistant. You canāt spoof gamma rays with a fake wallāor sneak through with stealth toolsābecause the systemās constantly checking that the physical makeup of the vault hasnāt budged.
š TL;DR: Some of the most secure bank vaults on Earth use gamma rays and neutron sensors to detect tampering from the inside out. It's not just high-securityāitās nuclear-security.

What did you think of this week's email? |
Until next timeāstay curious, stay critical (like a reactor core), and may your takes be hotter than a pebble-bed at full tilt. š„āļø
