Shidaowan CAP1400-2 (Guohe One)

Current state

Notes

Status moved to Grid connected 2026-09-28 on WNA grid date + Wikipedia operational listing — both secondary; commercial-operation date still blank everywhere, so not commercial. Construction start backfilled to 2020-04-21 (WNA reactor page; populated 2020 refined). Owner SNDPC (org:state-nuclear-power-demonstration-plant): Huaneng 25% at end-2023 per its 2024 bond prospectus, balance SPIC-side; WNA's SPIC 55% / Huaneng 45% is the 2009 founding split. Sister Guohe-1 grid Nov 2024.
