Overview
The Boiler System converts heat from the reactor coolant gas into steam used to drive turbines.
In an AGR, boilers act as heat exchangers between CO₂ gas and water.
What it does
- transfers heat from CO₂ gas to water
- generates high-pressure steam
- feeds steam to turbines for electricity generation
How it works
- Hot CO₂ gas enters the boiler
- Gas flows over water-filled tubes
- Heat transfers into the water
- Water boils and becomes steam
- Steam is directed to turbines
- Gas cools and returns to the reactor
Key Components
- Boiler Tubes
- Steam Drums
- Heat Exchange Surfaces
- Pressure Control Systems
- Steam Output Lines
Why it matters
⚠️ Warning
Boiler failures can disrupt heat removal and power generation.
- Converts reactor heat into usable energy
- Protects reactor by removing heat
- Links reactor to turbine systems
Operator Notes
💡 Tip
Watch for pressure and temperature mismatches — they often indicate flow issues.
