Radiation levels in Pripyat

What were the radiation levels in Pripyat at the time of the accident? I am trying to find archival documents that talk about the radiation levels of the city 10-20 minutes after the accident. The city was only 10-15 miles away from the plant. If you lived in an apartment complex closest to the plant, say 10 miles away, what would be your dose if you were standing outside in the elements after the explosion?

Clinton Power Plant

Hey all, just wanted to ask a bit about the Clinton Power Plant. Is there anybody here who works at, or has worked at, that plant? How’s the work culture? Operations turnover rates high or low? How hard do they tend to work your crews over (which I have no problem doing hard work at all, I’ve worked in a production plant before without an issue while shorthanded)?

Just wanted to get an idea of how people like, or dislike, the plant overall.

Thanks!

Walmart signs 30-year nuclear power deal with Constellation in Illinois

A retailer signing up for nuclear power is a pretty clear signal that corporate energy demand is getting more serious.

Walmart signed a long-term power purchase agreement with Constellation for carbon-free nuclear energy from the Dresden Clean Energy Center in Illinois. Walmart will receive power across two consecutive 15-year terms, which makes this a 30-year procurement signal rather than a short marketing gesture.

What changed: nuclear is moving further into corporate power procurement, especially for large load buyers trying to secure long-term carbon-free electricity.

What did not change: nuclear power still sits inside a very physical supply chain. It needs uranium fuel, transformers, switchgear, high-voltage equipment, backup systems, cooling infrastructure, transmission connections, and a lot of copper wiring before the electrons reach facilities.

Gunnison Copper connects directly through that copper-intensive power layer: company materials identify it as an Arizona copper producer and developer, and large power deals like Walmart's depend on grid and electrical infrastructure where copper is a core material. The bridge is not nuclear fuel; it is the copper required to move firm power into real buildings and operations.

Why nuclear fission is the future

We are witnessing the slow death of the fossil fuel era, not because we’re running out of oil, but because we’re running out of Exergy. In the golden age, Texas and crude Arabian wells delivered an ExEROI close to 20:1. Today, that net energy return is collapsing, and our financial system is desperately printing fiat money to mask this physical deficit. The current global economic stagnation is just physics catching up with finance.

We need a brutal reality check. Fusion is a beautiful scientific carrot on a stick, but we can't build today's civilizational baseline on 30-years-away promises. Fission is the only mature technology capable of unlocking the massive energy density required for true societal and energetic independence.

Look at China’s Gen IV and thorium deployments—yes, there are engineering bottlenecks, but they are material problems solvable through capital and industrial willpower, not theoretical physics breakthroughs. Fission isn't just a tool to lower emissions; it is the ultimate geopolitical and social firewall. A society with a cheap, abundant, and hyper-dense nuclear baseline is a society that cannot be blackmailed by resource scarcity or rentier monopolies.

NRC lawsuit could hand states power over advanced reactors

Valar atomics is one of the company suing the NRC claiming that advanced, small and micro nuclear reactors shouldn’t be regulated by the federal agency because they are different than a large skilled regular light water reactor. But here’s the con job- if they power a data center, then they’re essentially combining multiple smaller reactors to make what is essentially a large scale nuclear reactor. They’re trying to get around being regulated, which means being able to dump radioactive waste wherever they want. That’s the bottom line. We must not let them redraw it.

Questions about the Post Interview Process

I was recommended on both the POSS and the BMST, and am hoping to hear about a follow up interview soon. Assuming it goes well, what do the next steps generally look like? For clarity, I'm applying with Constellation. I'm hearing that there's a drug screening, a psychological evaluation, a physical, and an in-depth background check? I'll be real with you; all this makes me very, very nervous. I know it's obviously incorrect to lie, and I have no intention of doing that. I also know that none of you necessarily have the inside scoop, I'm just asking for reasonable thoughts and assurances, cause I'm going to be quite frank about the things I'm concerned about.

* I had an edible gummy in a recreational state three weeks ago. I know Constellation is a zero tolerance workplace, but I have no history of misuse in the workpalce.

* I have autism, is that going to make the psych-eval harder?

* I was diagnosed with depression as a teenager, but I always thought that was more circumstantial than anything else.

* I don't have **any**, and I mean **ANY** Criminal history, but I do have maybe ten tickets over the last twelve years or so. One for speeding, and the others for various forms of incomplete documentation or paperwork, or something like a cracked windshield (All of which have been paid).

* Technically I'm behind on child-support payments, but they aren't administered through the state, and they've agreed to not pursue them for personal reasons.

* What sort of information is the PHQ going to ask of me?

* I can only really think of, maybe, five non-family members I can use as references off the top of my head. I'm not exactly the most social person.

* My credit is really bad, like in the five hundreds I think, because I didn't have a lot of support when I was in my early twenties, and I've mostly avoided any sort of payment plan since then.

* The dates of employment on my resume aren't exact; they should be in the ballpark, but I didn't go out of my way to confirm them.

* I was fired from one of my experience-relevant workplaces, but it was for attendance issues related to my fiance being ill.

* I haven't filed taxes in around three years; the first year was due to me being owed a rebate and simply not having time to claim it, and the other two times were because I wasn't drawing a salary and just helping with my fiance's business.

* I'm not jacked, but I'm not super fat either. I don't workout, but I stay relatively active by walking my dog a few miles every day..

I really, really want this job. Am I just cooked? Does all of this seem like relatively normal stuff? I'm just deeply worried than they'll onboard me, I'll upend my life to move towards the facility, and then they'll cut me loose because of something in the background check, or the physical.

Fire Suppression

It dawned on me that any place where fissile material is stored would have a potential problem most places don't, when it comes to fire. If you had a fire in, say, a nuclear fuel fabrication facility you probably wouldn't want to dump a ton of moderator into the rooms where the fuel-to-be is being stored. They had to have considered this during the planning, so if anyone knows anything about how fire suppression is handled in a facility like that, I'd be curious.

Would it even be problematic to add a bunch of water in a situation like that? Obviously there's water in a reactor core, but there's also a lot more concentrated fuel, and shielding.

Why are people so anti nuclear

​

Nuclear energy is one of the most green while large scale power source. The radiation coming from a nuclear plant is less then from a coal plant. 1 uranium dioxide pellet is about 1 TON of coal and there are thousands of those pellets. And people complaining about nuclear workers problem is also not like they say it is in a gas power plant the injury rate of workers is up to 99%. Another thing is waste and this is actually the one I kind of agree with BUT we have so controlled and good storage that it isnt harm to us nor nature and in France they even recycle it to MOX fuel but takes a while and is expensive. Also accidents are catastropic but now a days it's super unlikely something even dangerous to the public happens rules keeps getting stricter and safety designs get better.

If you are anti nuclear tell me why I'm open to other opinions but keep it respectfull.

Neutronix (A Nuclear Reactor Sim)

Hey all! So just out of boredom I started a project where I figured I'd do a simple little sim for a reactor in UE5. After it grew a bit, I thought that maybe other people might enjoy it and that it maybe had some potential. So -- for your consideration -- I present "Neutronix". You can find the download in the link below. Any feedback is appreciated. Please note that this is not a 1-to-1 sim by ANY means and serves more as an "educational" tool.

(P.S. I do not use a traditional reactor design. Instead, I use control "drums" with a reflector and absorber side to control the reaction.)

Appeal decision to deny unescorted access

I would love to hear some success stories of people who have successfully won their appeal when they're unescorted access was denied.

TLDR: based on the information below, what are my chances of winning my appeal? Has anyone else successfully gained unescorted access through an appeal to the psychologist opinion?

Story time:

I have been in nuclear power for 25 years. I have licensed senior reactor operator at two plants. For the past 2 years I have been out of nuclear and focusing on my mental health.

I made the decision to return to nuclear power after a bad experience at my job with dishonesty and lies.

I applied for a position at a plant that I wanted to do work at as an SRO. Having previously licensed, the two plants allowed for me to get a pretty good offer. It was basically a no-brainer on Mike's side of the pay and the company side knowing that I can successfully complete the license course.

I was all set to start work next week. That is until Tuesday morning. I received a call from access control informing me that my UA was being denied based on recommendation from the psychologist. I have not received a formal rejection letter but I have received the formal recession of the conditional job offer. So far all I have heard is that the psychologist would like me to while not an employee. Check in with them monthly over the next 5 months so that they can verify the stability of my condition and the medication that I am on.

I feel this is unnecessary due to the fact that my condition has been stable for the last 8 months along with me having been on the same medication for over a year. The dosage on one of my medications was increased in March not due to relapse but due to just trying to dial in the medication.

My primary care doctor has written a letter stating the stability of my health conditions and medication that I am on. This includes monitoring of blood work to ensure no adverse effects of my high dose of medication is affecting me. My therapist has written a letter stating my condition as stable and having improved over the last good bit of time. My psychiatrist has also written a letter indicating my stability, the medication and how well it's working. And the reason for my dose increase not being a relapse but just normal maintenance adjustment. Additionally, he actually took the time to research and figure out what duties and responsibilities a senior reactor operator has, including that of evacuation of the control room. He has stated that I will be able to perform all duties normally while on my medication and that my condition is stable enough to warrant unescorted access. Additionally, he States that the side effects of a missed dose are minor and include things such as nausea and headaches, but the solution is just as easy as taking the missed dose.
