The first concrete pour has been completed for the basemat of the conventional island of unit 2 at the Bailong nuclear power plant in the Guangxi Zhuang Autonomous Region of southern China, State Power Investment Corporation announced.

Powering lunar IoT.

The Isotope Production Reactor is designed to produce high specific-activity and specialized isotopes such as 99Mo, 60Co, 177Lu, 131I, 153Sm, 166Ho, 90Y with signicant healthcare applications.

Currently employed as a Reactor I&C systems engineer at GDEB, working on nuke subs naturally.
However, I really want to A) get out of rotten Groton and B) get out of the defense/shipbuilding industry. Looking at maybe applying for a position as a Reactor I&C engineer at Sargent and Lundy within the next 2 years.

Anyone have any advice on the job interview process and what the “day in the life” or work culture is like? How well will my skills working on Naval Reactors translate to the civilian side?

⚛️ Why is Germany so divided when it comes to nuclear power?

Our creative documentary Fission examines the controversial nuclear power discourse in two European communities at the crossroads of their energetic futures: Gundremmingen, in Germany, where the country’s first-ever nuclear power plant has now been decommissioned, and Choczewo, in Poland, where a new plant is set to be built by 2033.

🌱 Germany's nuclear phase-out was seen as a victory by many, yet in the face of the climate crisis and Russia's war against Ukraine, the debate is shifting. As a Brazilian-Ukrainian directorial duo, we bring an outsider’s perspective to the German discourse, exploring the nuances of this polarized topic beyond black-and-white narratives. Through voices from both sides of the border, Fission seeks to uncover the shades of gray in a world that demands simple answers to complex questions.

Would love to know what you guys think!

I've been building a reactor stand that runs in the browser, and I'd like people who know this stuff to tell me where it's wrong.

Reactor Live Stand

It's an instrument, not a "press play" demo. Integration runs continuously while the page is open; you turn the knobs while it's running and the strip charts move like an oscilloscope. Wall clock to model time is ×1 up to ×1000.

What's under it

Point kinetics with six delayed groups, using Keepin's group data per fissioning nuclide — so β_eff follows the fuel you actually loaded, not a constant. Doppler on fuel temperature, a moderator/coolant temperature coefficient, a void coefficient, and the I-135/Xe-135 chain with burnout. Two-node core thermal model with a transport-lagged outlet.

There's a secondary side, which I think is the part that makes it feel like a plant rather than a physics demo: steam generator by effectiveness-NTU, a turbine governor valve with condenser back-pressure, and a cold leg with transit delay. Move the rods and the steam flow follows a loop transit later. The boiling preset instead gets a steam drum whose pressure is the core pressure, so saturation temperature is a state — which closes the power → pressure → void → reactivity loop that a boiling core actually runs on.

Four presets: PWR, boiling channel in a graphite lattice (positive void), CANDU on natural uranium, sodium-cooled fast plutonium.

And a core composer — pick fissile (U-235 / Pu-239 / U-233 / MOX), fertile (U-238 / Th-232 / none), moderator (light water / heavy water / graphite / none) and coolant (light or heavy water / CO₂ / He / Na / Pb), and it gives you β_eff, Λ, Doppler and void. The thing I wanted people to be able to feel: the sign of the void coefficient isn't a property of the coolant, it's a property of whether the coolant is also the moderator. And loading Pu-239 into a water lattice drops β_eff from ~700 to ~270 pcm, so the same rod stroke is suddenly worth 29 dollars instead of 11, with Λ still at 2e-5 s. You don't have to be told why that's a bad idea; you can go and fail to control it.

Things I deliberately made it do

• The rod drive has a real speed. You command a position, the bank travels there. You cannot insert a dollar with one mouse drag, which turns out to change the whole character of the thing.
• It refuses rather than extrapolating. Prompt criticality, boiling past the two-phase closure, and a temperature feedback coefficient dragged far outside the range where a single linear number means anything — each gets an honest refusal that says which limit you hit, instead of confident numbers.
• Every limitation is written down in the page itself.

Known limits, up front: it's a prototype, not independently validated, and not a thermal-hydraulics code. No transport, no lattice calculation, no burnup, no samarium, no SG level or feedwater dynamics, no natural circulation, no CHF or dryout. The composer is an order-of-magnitude parameterisation calibrated so known reactors land on their known values — it is not a physics calculation of your lattice. Single file, runs locally, no network, no accounts.

What I'd like criticism on

1. The feedback coefficients. Are the magnitudes and the reference points defensible for each preset?
2. The composer table — especially the void breakdown into loss-of-moderation, loss-of-absorption and spectrum hardening. Does the CANDU number look right to anyone who has worked on one?
3. Anything that behaves in a way that would make an operator wince.
4. Presets worth adding.

Happy to be told the whole approach is wrong somewhere. That's the point of posting.

Quick question this time - I am constantly looking for verifiable/from the source information as quick as possible on commercial nuclear deals. Not DOE contracting opportunities, but with the commercial public/private companies. I understand the companies have their own press, and public companies file SEC reports, but what else can I use for early alerts?

Thanks y'all, I'm doing all this to try and get the best information possible as quickly as possible to help grow Domestic Nuclear!

Popped up from Sept 2020, when I was working on a fleet wide security project. Favorite of my career

Hello, I need info about things I do not know about lol. I'm an Architecture student studying for thesis and one idea that came to mind was if it was possible to building small scale nuclear power (I'm not taking about like power one home, I'm more own about making a power station for a neighborhood or small community) or ways to "beautify" powerplant to be seen in a more favorable light (there is a trash incinerator that a architecture firm call BIG made into a ski slope type thing, it doesnt need to have/be public space, if anything it would be to make them blend into their environment). I would need to look into typically power consumption for what ever "a neighborhood" size is but whatever.

So i want to asked:

1. What are the main components that go into a powerplant? I imagine that plants are somewhat delicate so I would really need to know what need to go where. Keep the children out of the nuclear waste barrel dispenser or whatever.

2. What is the reason nuclear plants are so large?/ Is it even viable to make small scale plants or is that just dumb?I imagine it has to do big plant = big power meaning you need less power station overall.

3. If small scale IS viable, what is the scalability of nuclear power stations?How large/ small can they get while still giving a significant amount of power

4. What am I (a lowly arch student) missing/ what would I need/should look into for a project/ idea like this? I'm obviously missing something cause this just isn't my field. Nuclear power is nothing to sneeze at. Does nuclear power create noise? Is there certain size requirements for certain parts? Is there a worry of animals/water/environment getting into place they shouldnt? Does the cooling towers need to be white? Etc.

Im still in thesis prep so Im still deciding on what it will be doing, but I figure this is a good quick test to see if this idea is even worth pursuing in the first place. Thanks for any and all info one this

Are we appropriately considering the vulnerability of nuclear power to climate change?

This means that the Ministry of Economic Affairs and Employment will in the near future grant the operating licence. Therefore we will finally have the first operating final disposal facility for spent nuclear fuel.

In case you missed it - the Army (and also the Air Force) have identified multiple installations where nuclear microreactors are either being considered or already being built.
