Linglong One passes non-nuclear turbine test, confirming energy conversion systems

China National Nuclear Corporation/Linglong One (ACP100)

The Linglong One ACP100 completed its non-nuclear steam turbine test on December 23, 2025, a critical pre-operational milestone. Workers operated the conventional island (turbine-generator, condenser, steam systems) at design parameters using external steam supply, verifying the mechanical and electrical systems would function correctly once the reactor supplies heat.

• Non-nuclear steam test operates the turbine and electrical systems independently of the reactor.
• All conventional island systems met design parameters on first attempt, confirming engineering quality.
• Test validates turbine-generator, condenser and heat rejection systems before nuclear operation begins.
• Successful test positions the reactor to proceed to fuel loading and hot commissioning.
