I was applying to NLO entergy and I read this in the application form.

"Pursuant to Title 10 Code of Federal Regulations Part 810,Section 57(b) of the Atomic Energy Act and Title 15 Code of Federal Regulations Part 734, these questions are for the purposes of maintaining Entergy's compliance with federal regulations. These questions are specifically permitted for non-citizens pursuant to Section 274B of the Immigration and Nationality Act and Title 8 of United States Code Section 1324 (b). "

chatgpt helped understand the code a little but i am not sure which roles or jobs are deemed sensitive.
does NLO position require US Citizenship ? do you guys have foreign citizens with work authorization that work in your facilities ?

I'm trying to gauge if it is possible to transition into the Nuclear industry without moving too far (I currently live in the Sacramento/San Fransisco Area).

I'm currently a mechanical engineer in the power industry working on gas turbine combined cycle and simple cycle power plants. I have a pretty wide range of experience including piping design, process design, controls and quite a bit of project management and field engineering. I'm also a PE.

I would really like to work on the design of Nuclear plants, but I don't know if this is feasible without relocating. The only company I know of around here is Kairos but I'm not sure if they're doing the work I'm looking for.

Any insights on the industry would be helpful and much appreciated.

Are there any physical requirements for being an NLO?

More speciality, can you be an NLO if you’re overweight?

Thanks!

This past Thursday, Engie submitted a note to the Belgian parliament as to the future of the remaining five operating reactors in Belgium.

The two that have already shut down: Doel 3 and Tihange 2.

Engie has explicitly stated that a return of operation is not possible for these two. Doel 3 has completed chemical decomm and proceeding with turbine dismantling. Tihange 2 has just completed chem decomm.

Regarding Doel 1, 2 and Tihange 1, Engie has stated that any extension will be "unfeasible", both economically and technologically.

Regarding a further ten year extension for Doel 4 and Tihange 3, Engie dodged the questions by stating "Ce n'est pas une option sur la table aujourd'hui". It's not an option on the table as of today. Engie left the door half-opened for a further ten year extension for Doel 4 and Tihange 3.

I give Engie this: they know how to play the political football, and complicated negotiations are ahead.

So just some background, I was a nuclear operator in the US Navy. In that time, many people I worked with, I would never trust/want to work with voluntarily. And these are supposed to be the smartest the military have to offer (this is kinda sarcastic).

I understand that civilian reactors are completely different in training, operations, and maintenance. But there still needs to be a certain level of quality in the workers. So I'm just curious what other people think.

In a typical US reactor, U-235 is the main fission fuel. How much of the heat produced by a reactor comes from U235 fission vs the subsequent decay of all the daughter isotopes?

Here's my dumb guess. After the Fukushima earthquake triggered a scram, the NRC report gave the reactor's thermal power at ~ 100MW (Figure 2.4 here: https://nap.nationalacademies.org/read/18294/chapter/5#40 ) . Chain-reaction Fission is done after the scram, so it seems like that residual heat would come from daughter isotope decays? Assuming each of the Fukushima units was 600MW electrical, ~1800MW thermal power (30% efficiency is probably too low?), this would mean that daughter isotope decays vs U235 decays would be 100MW/1800MW ~ 5% of the reactor's power output?

Hi, I‘m 14 and completely addicted with this whole „Nuclear Topic“, and I have one Question: Is there any Kind of Reactor-Simulator for the iPad? I‘m Now in the Phase where I want to Learn about much of the Details of Nuclear Reactors, and I Hope that I can get those Informations of These Simulators I‘m asking for!

Hey I'm a Hs senior taking a climate literature course, and our project is currently working on effective climate communication. We (me+4 classmates) are focusing on nuclear energy and are making a video documentary-ish and it would be cool to include a little vlog to some related place, however, I can't seem to find anywhere revenant to visit within the city. Some college tour would be cool, but idk how to coordinate that.

Is there any kind a pc based simulator or even a game like sim city where you get to run a nuke plant?

It would be fun

Hello. I graduated this summer, and dreaming to work in a commercial reactor (ideally NLO). But there is a small problem. I live in Kazakhstan with the resulting problems.

Do you have any good tips, recommendations to try to get a job in commercial reactors in the States/Canada?

I don't really want to go to master degree, because a bachelor's in nuclear physics was enough for me. (I understand that no one needs me there, but it's still worth a try)

I know next to nothing about nuclear power but I find molten salt reactors very interesting. I heard about tritium leaks being a cause of concern in the nuclear industry, so I wanted to ask two questions:

Do molten salt reactors leak tritium? From what I've read a lot of the leaks come from the water used as coolant so I was wondering if it was relevant to nuclear reactors who don't use water as coolant.

Also, are tritium leaks a considerable inconvenient to nuclear power usage or are they neglectable? I tried searching about it but depending on the source, the answer can vary.

Thank you in advance.

I'm a former Navy Nuke and retiring from the service in early 2026. I did 12 years in submarines before switching communities. I grew up in the Twin Cities of MN and would love the opportunity to return and raise my family there. Ultimately I'll need to go where the work is though, so trying to set myself up for the best chance of getting work in MN.

Anyone here work at either of the MN Excel plants (Prairie Island or Monticello)? I'm trying to get an idea if there would be job opportunities for me, even though it will be 8 years since I was directly involved in operation of a propulsion plant. I understand things will change in 14 months, just want to understand my chances. I also understand I won't be able to walk in to a high level position on day one since my Navy training/experience does not directly translate.

Ideally, I'd like to get involved in tracking and planning maintenance schedules since that is closest to what I did in my last nuke tour. Would also be interested in radiation physics/rad health but I don't have a degree in that so not sure if my Navy time is enough to get me an interview for one of those positions. Not sure if Xcel would make me stand watch as RO for a few years and then apply for an internal move to one of those other areas.

If any of you work at either plant please let me know your experiences working there. Any certifications I should spend my time on before retirement? Does a non-current Nuke with a computer science degree stand a chance of getting an interview at a nuke plant? Other opportunities in the metro for vets and nukes?

Thank you in advance for any guidance you can share.

I'm struggling to understand a concept relating to positive and negative void coefficients, hopefully someone could help me out here as I cant find a clear answer online and various AI tools keep going around in circles no matter how I phrase my question.

In an RBMK reactor, the coolant water absorbs neutrons more than it moderates them, which as I understand is why it has a positive void coefficient (Not enough water leads to too much moderation by the graphite and too little absorption by the water).

In an LWR reactor, the water has the opposite effect, acting as a moderator more than a neutron absorber, so a lack of water decreases net reactivity - no chance of a big boom like at Chernobyl

My query is: how on earth can these properties be completely reversed by designing the reactor differently? I just don't understand how water can have an overall moderation effect in one situation, but an overall absorption effect in another. My (light) research seems to hint that it's to do with the fuel type and neutron economy etc. but perhaps someone with a big brain can explain this :)

Thanks!

Got bored at a conference and replied to some posts over there that were based solely in bad propaganda that was easily disproven with readily - accessible resources available online.

Even the moderator in charge of the subreddit was replying with completely wrong answers that show they have a fundamental lack of understanding of energy markets or technology, and doesn't keep up with actual news of what's happening in the energy world. I asked what their background was in energy, and have had some of my questions about that deleted?

I'm just very confused, since they like throwing around the terms "misinformation" and "propaganda."

I'm asking this as I'm an expert in international energy modeling of systems and economics who's currently hanging out in an airport on the way back from Baku.

So as the title says I know pretty much nothing about nuclear energy. so here’s some questions for y’all (Please in layman’s terms im an idiot) Edit: when I say nothing I MEAN nothing

1. Why did Chernobyl happen
2. Why did 3 mile island happen
3. What are the differences between reactor types
4. What is the difference between Soviet, American, and French reactors and plants
5. Pros and Cons of modern Nuclear energy
6. Comparison of Old and modern reactors and plants

Edit: Thank you so much to the people who took some time out of their day to try and explain something as complicated as these to me, I know they’re all really complex and worthy of their own threads and I’m just grateful y’all tried to answer them.

So I have been listening to podcasts recently about getting a push for more nuclear power plants and how they are safer and greener. I accept that the number of deaths per year from different forms of power generation in low for nuclear. I also accept that the overall upfront affect on the environment is low. My issue is when the unit melts down, the area of effect is larger and long term. So my question is, what is the clean up and mitigation process? What can be done to the exclusion zone around Chernobyl to get people living and farming there. The time frame should be no more then 5 years to be feasible in a populated area that needs housing and food.

Hey all, so I have been offered a position at my local plant as a utility operator. I am very excited about this position but I have a question about the background check portion of the onboarding process. my understanding that the background check is more in depth than the standard check since we will be working with critical plant equipment, so they do an FBI background check. I have had a record expungement in the past so I do not have anything on my criminal record anymore, but I am curious about filling out the criminal history portion of onboarding. Will their background check bring up anything that has ever been on my record? do I say anything about it? I am not wanting to lie because as far as my knowledge is about the expungement, is that it is no longer there. I just do not want to say I have no criminal history and then their background check shows things that were once there. FYI my criminal history did not include any drug or felony charges.

Hello everyone, I’m new here and I’m giving a persuasive speech on why nuclear energy is a better alternative to fossil fuels, mostly targeting coal specifically. For this speech I need 3 physical sources, and I currently only have 2. I have the book by Gwyneth Cravens, “Power to Save the World the Truth about Nuclear Energy”. As well as an interview with someone who recently retired that worked on a Nuclear plant for years. Does anyone have like any books or articles that I could use as sources? I’d prefer if it’s something that is technically a physical source that I could find online. (Like e-books). Thanks for any input.

As I understand nuclear reactors, it's basically a pile of heavy unstable material that self catalyses it's own fission. When the reactor blew up and all the innards went flying out, why did they continue to be radioactive?

I'm not trying to ask a stupid question here, but I just don't understand why a reactor that was built around a bunch of fissionable material being in close proximity didn't just stop working when it exploded.
