There is no state in the U.S. where a majority of people recognize nuclear power as a low-emissions energy source, per new polling.
That's despite high levels of support for atomic power generally.

⚛️ 5 systems thinking takeaways from the benefits of smrs:
1. passive safety → simpler systems → fewer failure points → lower regulatory & insurance costs
→ self-cooling designs reduce operational risk + unlock faster approvals
2. smaller physical footprint → lower material & land use → faster construction → scalable deployment
→ minimizes site disruption + enables modular scaling like lego blocks
3. flexible siting → power anywhere → grid resilience + energy independence
→ air cooling + modular design enables power for remote bases, disaster zones, off-grid towns
4. factory fabrication → standardization → lower costs (wright’s law) → faster iteration
→ learning curves + repeatable builds lead to affordable, high-quality nuclear
5. distributed power → decentralized energy systems → more reliable grids + local control
→ smrs enable energy sovereignty + redundancy in grid-critical zones

in 1956, martin (now part of lockheed martin) ad for transportable nuclear power. it foreshadows what would soon become the us army’s army package power reactor (appr) program
5 lessons from martin’s 1956 nuclear ad for scaling microreactors today:
1. think small, build big
→ high-density energy in compact form is the ultimate logistics unlock.
2. design for deployment, not just performance
→ field conditions break elegant systems. simplicity wins.
3. build for autonomy
→ minimal crew, remote ops, smart controls = scalable resilience.
4. fuel matters
→ next-gen fuels like triso or haleu unlock safety + longevity.
5. failure is a data point, not the end
→ appr reactors had flaws. today we have better tools, materials, and urgency.
action: combine defense urgency + commercial innovation to bring microreactors from lab to field. energy independence starts with resilient kilowatts.
ad astra!

“The couple was considering building a facility into a quarry’s hillside, but when they got word that the former nuclear plant was starting a new life as a business park, they looked at the reactor building. “If you can’t find a mountain, you make a mountain,” he says. He made that mountain inside of WNP-3.”

while this eo includes support for revitalizing coal, it also introduces broad regulatory reforms that open the door for nuclear:
- forces outdated energy regs to justify themselves or sunset
- applies to nrc (YES!), doe, epa, ferc
- adds pressure for modern, innovation-aligned regulation, which brings a hopeful pathway for microreactors and smrs
a solid step for nuclear—if we push it further, work together with much more hard work ahead of us to scale nuclear energy in america

61% of American adults support using nuclear power -- nearly a record high, and up six points since 2023.
https://paragraph.com/@kaufman/the-us-just-moved-closer-to-recycling-nuclear-waste
some takeaways from @kaufman piece on us and its steps to recycle nuclear waste:
- big shift: the us is starting to recycle nuclear waste
- partnership /with curio + orano teaming up to turn waste into reusable fuel, which leads to less storage, lower risk, more clean energy
- a feedback loop begins: tech sparks trust → trust shifts policy → nuclear future feels possible again

The Power to Save Lives: Why Nuclear Deserves a Second Look
🔗 paragraph.com/@davidtphung/the-power-to-save-lives
i used to think energy was just about power grids. then i learned last year: a city of 500k loses about 81 lives/yr to coal. nuclear? just 0.2. it’s not just clean — it’s the quiet life-saver we’ve overlooked and it deserves a second look.
i’m excited to help build the next generation of nuclear reactors — not just for clean energy, but for a future where humanity has all the power it needs to thrive.⚛️ /keepgoing

i enjoyed this open and closed fuel cycles diagram
open cycle: use once, store waste. simple but inefficient.
closed cycle: reprocess, reuse fuel. efficient but costly, higher risk.
trade-off: simplicity vs. sustainability.

⚛️ nuclear ≠ just energy, it’s a systems-level climate lever.
lessons:
1. scale = co₂ drop
2. fuel cycles matter
3. modular cuts cost
4. long-term stewardship needed
action: invest in tech, policy, and trust. reboot the future, atom by atom.

tonight’s nuclear film: atomic ambition meets antarctic reality.
in 1962, the us navy built a nuclear reactor at mcmurdo station. it cut diesel use but failed from leaks, cracks, and radiation risks. shut down in 1972, it’s a cold war lesson in fragile systems and unchecked ambition.
we’ll be back soon with new microreactors.

what we lost when san onofre shut down
→ 5–7% of california’s electricity
→ 19% of power in southern california
→ 2,200 mw of clean, 24/7 baseload
what replaced it?
→ ~1,600 mw of natural gas- fired powered which was protested by the sierra club for its emissions
→ ~600 mw from renewables + storage
→ demand response, flex alerts, energy cuts

just finished watching nuclear now (2023) with 5 lessons and 5 actions to take
lessons:
1. energy needs are growing fast – we can’t meet future demand with renewables alone.
2. nuclear is dense, clean, and reliable – it’s the only scalable 24/7 carbon-free source.
3. fear ≠ facts – public perception is shaped by misinformation, not data.
4. politics, not physics, blocks progress – fossil fuel lobbies and cold war-era fear delayed adoption.
5. history proves it works – france, sweden, and south korea show safe, effective nuclear at scale.

insight into the bwxt triso fuel process line process for microreactors and space reactors
so what is trisol fuel?
triso fuel is meltdown-proof nuclear fuel made of tiny ceramic-coated uranium grains—each one a mini reactor core.
it can withstand extreme heat and radiation, making it ideal for microreactors on earth and in space. ad astra!
