Keep the power alive, without melting the core!
Your goal is to produce 100 units of energy at the power generator (at the top). You will lose if the core temperature goes above 300 units.

Water flows counter-clockwise in both circuits (except when things start to get out of control!). The heat exchanger (in the center) transfers heat between the primary circuit and the secondary circuit.
You can: - Control water pumps - Open/Close valves - Control the immersion of the control rods in the reactor core.
The underlying hot water flowing simulation is made of ad-hoc formulas (although the water is conserved!), please don't build a nuclear reactor at home based on my design :D
Tip: start by setting the control rods to 0, so the core will stop generating heat and won't melt in less than a minute.
To get a better understanding of what's going on, use the spacebar to toggle the display of physics quantities. Can you win without using this mode?
Keys: - 'R' : retry - Spacebar: toggle the debug mode, showing pressures (P), fluid quantity (N), and temperatures (redness).

I'm missing some feedback, I want to see my core exploding in a big boom !
I didn't know what I am doing :) but figured maybe steam will need more heat and tried to get heat from the other circuit and it worked :)
nice entry man.
Once I got it running reasonably, it was kind of fun, though my pressure started bouncing between 0 one frame and 1200 the next, and eventually stopped flowing through one of the two pump circuits for some reason. I was able to win though, in the end! This reminds me a bit of when things go horribly wrong trying to set up a steam turbine in Oxygen Not Included... ^_^
Of course my reactor melted a few times before I decided to shut if off first. Then it's quite simple, turn on all pumps to the max, and raise the reactor core step by step. Check the temperature whether it stays stable. And then it's off to winners land :)
This really needs a background humming sound! Well done!
I can understand the basic idea that water flows from the core, to the heat exchanger, and then in a second circuit to the steam engine. After some experimentation I could get it to produce power. But what I still don't get is why there are so many valves, and if it matters which pump I activate.
On my PC, at the start it overheats in seconds, you have to be quite quick to set the control rods down to 0, or the game is over before it even starts.
I finally made it, but it was very hard and it took me some time.
The physics simulation is a great idea, but some help would help.
I would disable rating Audio, if you have none.
Also, the debug interface gives nice values and red indicators so I knew what was actually happening. I think it makes more sense for that to be the core game, specifically the colors because they give the player a sense of what's overheating.
It seems like there's a lot going on in the backend simulation, but I'm still very confused about the goal of the game. I did manage to keep it from overloading in a few seconds, and kept it stable for a while.
