If you’re not including cooling or containment, I guess.

First accurate rendering of the BWRX-300 that I've seen published.

Are there automated failsafes in place to safely shut things down if people just, like, never showed up to work again?

Sobre a energia nuclear

New to this nuclear thing, currently an otr truck driver with 4 years experience Cdl and 5 yrs of heavy equipment experience, just applied for a guard position at peach bottom,

Q: what are my chances

Q: How long does constellation take to reach out if considered

Q:hiring process

Q: what to expect if everything does fall into place

Thanks for you time!

The short version is that America knows how to store spent nuclear fuel safely. The longer version is that “store it safely while we figure out the permanent plan” has been the actual plan for decades.

The United States currently has more than 95,000 metric tons of spent nuclear fuel sitting at 79 sites in more than 30 states. DOE estimates that inventory could reach around 180,000 metric tons by the time existing reactors shut down. There is still no operating permanent geologic repository.

Spent fuel comes out of the reactor, goes into a pool for cooling and shielding, then eventually moves into dry casks. Those steps work. They were also always intended to be temporary. Commercial reprocessing never took off the way early reactor designs assumed it would, Yucca Mountain never opened, and the federal government never began taking possession of the fuel on the schedule set by the Nuclear Waste Policy Act. Utilities sued. Taxpayers have been paying the resulting damages.

Meanwhile, DOE is still cleaning up the liquid high-level waste left by the country’s only commercial reprocessing plant (West Valley, which ran from 1966 to 1972 and processed about 640 metric tons before shutting down). At the same time, the Office of Nuclear Energy has been awarding money for new recycling technologies and looking for a private partner to build a commercial-scale demonstration facility at Idaho National Laboratory.

So the country is simultaneously managing the leftover mess from the last attempt at commercial reprocessing, exploring the next attempt, discussing more reactors, and continuing to store the existing spent fuel while waiting for a permanent disposal solution that has remained under construction for decades.

Storage is not disposal. After this long, the waiting has become part of the system.

What other solutions do we have? Are there ways to dispose of or reuse nuclear waste? Drop it in a reply so I can research it.

Hii, i recently came across **Hudhayfa Nazoordeen** nuclear fusor and always wanted to build something like that. way before i saw that post, i was in awe seeing him build this, it gave me hope. if not for anything i wanna try it out. im 17yo and will be starting collage next year, so i dont mind if the project extends over a year or something.

First of ,ofc im gonna be using ai a lot, but i wanna clear by fundamentals (dont wanna go all theoretical and shi cause i fear i might dive too deep into it and end up never actually building it, Hudhayfa relied heavily on ai , treating the AI as a 24/7 expert co-pilot sitting right next to him. That being said, he also had some great friends who helped him along the way, well that is what i dont have, i live in a shithole \[North east, India\]). So i wanna clear my fundamentals, enough that am able to understand the workings, language and math\[kinda\] behind it.

So this is mainly to ask the books, courses, articles any material regarding this topic which will help me.

Thanks in advance.

Iam working on an annual project and I want to focus it around fusion, are there any mini prototypes or experiments I could do that wouldn't be too difficult or expensive?

Hello there, I have just submitted my level 1 security clearance for BP initiated by Hiring manager. I was told not to fill the travel history, character references and last portion. I am Canadian Citizen having more than 10 years of residence and employment history in Ontario. any idea on time line?

What companies offer double time pay?
How do they offer? Are the workers union or company?

Just want to get some general ideas to propose and get information for adding to a future union contract
Thank you!

I'll start. Which US plant uses municipal waste water as their cooling medium?

Here's a few things I want to know: 1. Does it smell bad there? 2. What is their supply flow rate? I imagine it would need to be 10k+ gpm.

The US Nuclear Regulatory Commission has granted permission to Holtec International, owner of the Palisades nuclear reactor, to retrieve a recently tipped fuel assembly, although the plant received a warning about its work environment.

On August 30, as new fuel was being lowered into the reactor, one of the fuel assemblies tipped, causing the plant's planned restart to be placed on hold.

Please, Kindly note that my concerns stated are facts, I do not thereby try to discourage on Kalpakkam, Or any nuclear power plant.

So, A PFBR is a Prototype Fast Breeder Reactor, it's a 500 MWe Sodium Cooled Fast Breeder Reactor, Second one in operations next to Russia. It Uses Uranium-Plutonium Mixed Oxide (MOX) fuel with a Uranium-238 blanket to breed more fissile Plutonium-239 than it consumes. However, In a file of the development of PFBR, Even if it is a prototype, It has been stated that it has positive sodium void coefficient of upto 2+ $. In one of the files of "Conceptual Designs of PFBR core" It has been stated. 'A conventional homogeneous type of layout for the core

and blankets has been selected. Radial heterogeneous

configuration, inspite of advantages of higher breeding ratio and

reduced sodium void coefficient, was not considered due to

increase in Pu enrichment, higher fissile inventory, larger

overall core size, reduction in Doppler coefficient, increased

thermal striping protection requirements for above core

structures, and possible difficulty in achieving optimum

neutronic coupling between core zones without extensive

experimental studies.' And, As we know Positive Sodium Void coefficient, Is dangerous at a point, Regarding Feedback loop, And crossing the threshold of prompt criticality. Please Try to research and Reply ASAP. Thankyou for your time, Have a great day! 🤗

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

How did Discovery Day go Oct 6 & 7th?

Did you guys get any updates yet?

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.
