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
