ACP100 (Linglong One)
ACP100 (Linglong One) is a light water-cooled reactor design from China National Nuclear Corporation rated at 125 MWe. Nuclear construction has begun.
The first land-based SMR anywhere to reach commissioning. Cold functional testing completed in October 2025 and the non-nuclear turbine ran in December 2025, with CNNC targeting commercial operation in the first half of 2026. Whoever gets there first sets the reference case, and on current evidence it will be China rather than any Western developer.
