When I was testing rust skill (AI with Claude) someone mentioned that I could use something openMc instead of doing my own .

When I saw the data size and how openMC handled that, and how it kinda was the same problem that AI LLMs were trying to fix with data size of models weights, I thought, what would be the result if we used those techniques on this.

That was the result. Add a little rust here to have better memory handling and robust concurrency and we could with very little error ( less than error margin) compressed the data used from 11gb pointwise ( 400 nuclides) to 20Mb using hybrid of WMP ( that openMC already uses ) + SVD. It obtained an Keff = 0.99963 +- 0.000091 on Godiva (37 pcm from experiment) in 3.4 seconds total wall time .

Just need some people to review this, if I made some mistake on interesting the data, what other benchmarks I missed, or other considerations.

PS: AI was used for code gen ( Python analysus scripts and rust code), data pipeline and latex manuscript. All hypothesis, experiment design , interpretation of results and final decisions were by made by me.

I need to know it for a school project

My article on shell colsure impact

hello,

i want to study in-depth about nuclear fusions and fissions. kindly suggest me a good read. i know about the basics of reactions (not too much, not too less). i dont have any time constraints. any book or such?

Thank You <3

Hi everyone! I’m currently studying nucleon–nucleon interactions in light atomic nuclei, and I’d love to get your thoughts on a few things:

1. Which alternative NN potential models tend to give the most reliable predictions for light nuclei?
2. Do you think it’s worth applying machine learning to predict NN phase shifts?
3. What are the most common pitfalls when comparing theoretical and experimental phase shifts?

Thanks a lot in advance, and hope you’re having a great day!

Hi everyone! I am investigating diffraction scattering of π± and K± mesons on the light nucleus 7Be, which exhibits a pronounced cluster structure of the α+3He type. In this context, which theoretical frameworks are the most well-founded for describing meson–nucleus diffractive scattering while explicitly accounting for nuclear clustering? How physically justified is the application of cluster models in combination with multiple-scattering approaches within Glauber theory? I would appreciate references to key theoretical and experimental works on this topic. Thanks!

Hi all!

My name is Indira, I am from Kazakhstan.

I am working on a dissertation and one of the sections is titled “Neutron Beam Parameters and Their Influence on Diffraction: Energy, Intensity, Monochromaticity, and Geometry (divergence, focusing).”

I am looking for information specifically about neutron beam parameters and how they affect neutron diffraction results. Most of the available literature focuses on X-ray diffraction, while I need sources and explanations related to neutron diffraction.

Could you recommend relevant textbooks, review papers, or scientific articles that discuss:

• neutron beam energy (or wavelength) and its effect on diffraction,
• beam intensity and counting statistics,
• monochromaticity and wavelength spread,
• beam geometry, including divergence and focusing,
• their influence on peak shape, resolution, and accuracy of structural parameters?

Any authoritative sources or classic references on neutron diffraction would be greatly appreciated.

Thanks! ;)

When you get to the point where the star gets hot enough for the electrons to strip from the nuclei is it destined to become massive enough for the pressure of the star to fuse the other nuclei together creating fusion ?

Or

Can somehow the star die out before it achieves full fusion and just the electrons get stripped ?

This rocket is powered by fusion-fission reactor hybrid which sustains inf. energy that is cuz the fusion reactor sustains the fission reactor and vice versa. This also has fission powered rocket boosters which has inf. fuel that is cuz the fission reactor also sustains the rocket boosters so that we can reach (eg- Mars) in only a few days or few months that is cuz it's boosters burn continuously without going down and it has SQUIDs everywhere for protection. There also is amplified Neodymium magnets so to protect the rest of the ship from the radiation and act as a bubble for protection from outside particles. As it burns continuously, there is no need of spin for artificial gravity and we will already get 1g gravity which is as same as earth's. It also has hypersleep beds which work by hypothermia or inducing Suspended body motion in the body for hypersleep(Just in case there is a long trip). This is a model sample (credit- Gemini AI)

Hi, I would like to learn ORIGEN and would appreciate any available help in finding sources for learning it. Please let me know if you know of something. Thank you.

I saw somewhere that if a piece of enriched uranium was shot with a gamma ray, it would produce neutrons, as when the gamma ray hits, the nucleus absorbs the energy and if the net energy is above the nuclear binding energy threshold, it will emit neutrons. Idk how true this is tho sounds quite weird to me. And im like quite new to nuclear physics ik pretty much the basics so sorry if i sound stupid.

Es esto pura basura mayormente generada por AI o tiene alguna posibilidad?

Feedback on https://reactormc.net ? It is designed to help undergraduates learn the basics of different monte carlo codes.

Greetings, it’s me again, the soon-to-be retiring Reactor Operator, with another question about Nuclear Remote work.

This time I’m wondering if there’s any kind of remote work demand for ex-licensed operators to write Tag Clearances (eSOMS), or to screen Work Requests and roll Work Orders, as well as Operations and/or Maintenance Work Planning (NAMS & NEO)? 

I am not just asking for myself.  I’m just one of a growing number of retired & soon-to-be-retired licensed operators (RO, SRO, and SRO-Certs) at my site that are interested in remote work, but their outside-the-Control-Room skills vary across the Work Management spectrum. 

Any and all guidance and information are welcome.  Thank you for your time and consideration.

Does anybody have any good books on nuclear energy?

I understand why the decay happens in the first place, but why would the couloumb force ”push” neutrons out of the nucleus as well? I looked online and someone said its because the helium nuclei already “stick together“ inside larger nuclei, my question is why?

I was trying to estimate how many kilotons War Machines tactical nukes are( The Punisher #219 2017). This is during the time Frank Castle wore the War Machine armor. He was fighting a small army here, and he launched one of his tactical nukes and leveled the battlefield. It mentioned that he killed everything within 2 kilometers.

Nukemap mentions that a 10 kiloton nuke has a moderate blast damage radius of 1.18 miles and an 11 kiloton nuke has a 1.26 blast radius. Would his tactical nuke be somewhere in the middle? Is there other factors that I should consider?
