Overview
This page outlines a basic startup flow for bringing the reactor online in a controlled and stable manner.
⚠️ Important
Startup should only be carried out when all major plant systems are available and stable.
Pre-start checks
Before beginning startup, confirm:
- No active emergency condition is present
- Cooling systems are available
- Reactor instrumentation is readable
- Control systems are responsive
- Safety systems are in a normal state
Basic startup sequence
1. Confirm plant readiness
Verify that key systems are available and that the control room has no unresolved critical alarms.
2. Establish baseline conditions
Check:
- Reactor output
- Rod position
- Core temperature
- Coolant flow
- Water level
3. Begin controlled startup
Raise power gradually and monitor the plant closely for any unstable trends.
4. Watch for abnormal indications
Pay attention to:
- Unexpected temperature increase
- Low coolant flow
- Pressure instability
- Water level deviation
- Rapid power changes
5. Stabilise output
Once the desired operating state is reached, maintain steady control and continue monitoring.
Operator notes
- Make changes gradually
- Do not ignore warning signs
- Pause the sequence if readings become unstable
