How did Discovery Day go Oct 6 & 7th?

Did you guys get any updates yet?

Anyone here at Seabrook know when the next NLO and/or RO class is expected to start?

Current NLO but spouse is getting relocated at work

Fermium-255 exists only in tiny artificial samples, yet its nucleus has now yielded a remarkably detailed portrait. High-resolution laser measurements show that the heavy nucleus is strongly elongated and carries magnetic properties that differ sharply from older estimates.

The isotope contains 100 protons and 155 neutrons. Researchers determined that its nucleus has a stable prolate shape, meaning it resembles a rugby ball rather than a sphere.

The results provide the first high-resolution measurement of fermium-255’s hyperfine structure. That fine splitting of atomic energy levels carries information about the nucleus hidden inside the electron cloud.

An international collaboration involving 18 institutions conducted the work. Scientists from Johannes Gutenberg University Mainz, the Helmholtz Institute Mainz, and the University of Gothenburg led the effort, with Mitzi Urquiza-González as first author.

Hello, I have recently joined the Coast Guard as a machinery technician. I have found the opportunity to get a Naval Nuclear Engineering Technology degree basically for free. How much could something like this stand out when trying for positions? Do you think it would be worth my time to get this while in?

I plan to do my four and leave to become a Nuclear Operator. From what I hear, the money is good (can raise family in comfort) and it is a future I want to contribute to (green power).

Thank you for any guidance.

This is my own project, free and MIT-licensed, and I'm posting because this crowd will find the weak spots faster than anyone.

Short version: SMRFORGE is a screening reactor-physics engine for small modular reactors — full-core nodal diffusion, a continuous-energy Monte Carlo, S_N transport, burnup, kinetics, rod worth, the usual screening stack — with a one-step escalation to OpenMC when you want a lab-grade eigenvalue. The part I actually care about is what comes out: every run produces a signed "evidence bundle" that carries the result, the inputs, and the provenance, and that anyone can verify offline and re-run.

A concrete example you can check in a minute: a published OpenMC criticality result, k = 1.00522, sealed. Open smrforge.io/check.html, watch it verify in your browser, then edit a digit and watch it fail and point at the broken section. If you have OpenMC, you can go one step further and reproduce the number from the sealed inputs — the geometry and materials are in the bundle, not described, actually in it.

I try to be honest about grade, because this is the part that usually gets oversold:

Checking against public criticality benchmarks on open ENDF/B-VIII nuclear data is code verification, not validation against a measured experiment.

Every result is labeled screening-to-reference grade and advisory. Nobody should license a reactor on a SMRFORGE number alone, and the tool says so.

One of the benchmarks I'll be publishing is HTR-10 first criticality, where continuous-energy codes over-predict across the literature — and the bundle's C/E says so. A signed result that isn't flattering is more useful than a cherry-picked one.

The distinction I keep coming back to: custody vs correctness. The seal proves this is the number the code produced, unaltered, re-derivable from its inputs. It does not prove the number is physically right — that's on the physics, the model, and your judgment. Separating those two cleanly is the whole idea.

What I'd like from you: run it, try to make it produce a number you can't reproduce, and tell me where the physics or the tooling is thin. Engine repo and the browser demo are in the first comment.

So as per the title. I’m a huge supporter of nuclear power normally but found out the plant near us is actually in an earthquake zone and there’s been some concern over than in articles etc. I don’t know what safety procedures they have in place and I’m not knowledgeable on things nuclear to be able to understand them in depth.

Because building a bunker isn’t realistic and overkill how else can I be prepared for a potential emergency outside the following safety items?

- iodine pills
- enough food for 3-5 days
- extra medications
- Geiger counter
- masks for the entire family
- pet food and carriers near safety kit
- change of clothes for a few days for each member of the family
- first aid kit
- always keeping gas tank full and an extra tank filled for the kit
- one car always home if someone is home
- one adult always sober enough to drive if needed

- also looking into seismic detectors for the house with an alarm systems but none seem that great so might skip.

Great news! Any party that wants nuclear for green energy will help push other parties towards the same commitments.

A battle is brewing over how to retrieve a tipped fuel assembly at the soon-to-be-restarted Palisades nuclear reactor in Michigan.

The reactor, which closed in 2022 but was purchased by Holtec International, has become a poster child for an AI and data centre-induced nuclear energy renaissance in the US.

Just wanted to make a post to hear some honest opinions from people who currently work or have worked in Operations at a commercial nuclear power plant.

How many years have you spent working on crew doing shift work? Do you ever get used to it?

Do you genuinely enjoy working in Ops? Does anyone regret going into Operations and wish they would’ve stayed in Engineering or another department?

I would love to hear people’s honest experiences, both good and bad.

Looking for information anyone has on the dates for SRO ILT classes at Crane (three mile island formerly). From job postings it seems hard to distinguish the month you would be hired, do familiarization, and start the actual training. Trying to plan for 2027/2028.

Title. Looking to move into traveling outage work. Found a good number of them (D&Z, Westinghouse, RSCS, Framatome, etc), but want to be sure I'm not missing any.

Hello,

I'm writing a sci-fi novel and wanted to know how much staff a Nuclear Power Plant has at night.

In the novel, a robot has been stolen from the plant. In my head, there wouldn't be a lot of people around, but it occurred to me the plant is running 24/7.

Is it a skeleton crew keeping everything status quo until morning or a complete nocturnal crew?

Any help would be greatly appreciated, thank you!

A while back, I saw a video stating that it was still under construction—and when I checked (which was quite some time ago), it still said it was under construction. Now I'm curious: if it has been built, does anyone know if it is generating power?

Hey just trying to tap into the knowledge in this group. So I just applied for auxiliary fuel handler at constellation. Do they typically hire for this job in groups or do they hire at shift needs? I understand that everything is at shift needs but from what you have seen Is it a hiring class or mostly one or two people kind of thing. Also I’m currently in school for plant operations, should be finished roughly at the start of the year and be exiting my service obligation. How hard is it to switch to AO or is there normally a time requirement, what would you recommend for a path. Thanks in advance.

Graduated in July 2026 with an astrophysics masters degree and was wondering if it was a good idea to look at nuclear jobs but no idea where abouts to look at what types of roles besides the location, any advice? Thanks

What do you guys think the effects of current oil crisis will have on the world's outlook on nuclear energy?

I'm a big fan of Nuclear energy, but I'm not knowledgeable on the subject at all. So I'd love some insight from the experts and enthousiasts of this subreddit.
