Praxis Nuclear Operator
Your shift has begun.
Welcome to the control room of the Helios Program's next-generation nuclear facility. Praxis Nuclear Operator is a detailed, real-time reactor simulator where you are in complete control. Your objective is simple: generate power, sell it to the grid, and turn a profit.
This is not an idle game. From the tension of the initial startup sequence to the delicate process of synchronizing with the power grid, every action has a consequence.
Can you handle the pressure?
- Master a complex machine: Juggle core temperature, coolant flow, steam pressure, and turbine RPM in a constant balancing act.
- Feel the stakes: Respond to flashing alarms and system degradation. Make the right call to prevent a core meltdown, a steam explosion, or a catastrophic turbine failure.
- Play the market: Use your profits to purchase new fuel, replace worn-out components, and upgrade your facility to meet ever-changing grid demand.
The grid is waiting, Operator. Don't keep it in the dark.

bro, you have to give SOME kind of guidance or tutorial. Your Operators Manual tells you what each item is and does but we need some kind of guidance on how the Process works.I dont know what the hell im doing and ive tried a bunch of different things a bunch of different ways. ive been playing this kind of regularly for a few weeks now and still have no clue what im doing or whats the right startup process
I am so glad to hear you are playing! Sorry about the issues. I sorta stopped really doing anything with it. But I hear you, I will make some adjustments today.
Thank you. No, it really is a great game. The UI is FANtastic, the parameters of all the peripherals are fluid and feel tangible. Its just...... well, its like just what the situation is: powering on a nuclear reactor having not the first clue on how to do it. looking through the user manual and flying by the seat of your pants! thrilling but frustrating when you cant figure it out after idk 40 or 50 times :)
