📢 Condenser Vacuum System Overhaul!

🛠️ In previous versions of the game, the condenser was… well, a bit easier to manage. The vacuum pump worked like magic — no need for motive steam — and condensation happened instantly. Convenient? Sure. Realistic?

With this update, things get a lot more interesting (and a bit more challenging!):

🔄 New Vacuum System: Ejector + Vacuum Pump

Vacuum is now generated more like in a real nuclear reactor:

  • The Ejector requires motive steam to work. It can’t create vacuum on its own.

  • The Vacuum Pump helps, but it depends on how the gases are flowing.

  • Condensation is no longer instantaneous — it's calculated realistically (yes, actual physics involved! 💡).

This means keeping the condenser in balance now takes some attention. But don’t worry — to help you understand what’s going on, we’ve added two new indicators:

📊 How to Read the New Indicators

Condensate Flow Rate

Shows how much steam is being condensed into water each second.

  • 🔼 High values: Lots of steam is entering the condenser, and condensation is working well.

  • 🔽 Low values: Might mean there’s little steam left, or that condensation efficiency is dropping.

This tells you if the system is actively turning steam into water — and how well it’s doing it.

Extraction Flow

Indicates how much condensed water (feedwater) is being pumped back to the steam generators.

  • If this value is higher than the condensate flow, you're extracting more water than you're producing — the condenser will eventually run dry.

  • If it's lower, water is building up — and the condenser could eventually overflow.

🎯 What’s the Goal?

Balance! You want the incoming steam, the condensed water, and the extraction rate to stay in harmony.

But don’t worry — it’s not about keeping everything perfectly stable all the time. When you're ramping up power, shutting down the reactor, or adjusting valves, temporary imbalance is expected.

PATCH NOTES:
