Nuclear Decommissioning Tracker

Kuosheng Nuclear Power Plant

Shut down · Taiwan · Immediate dismantling

Kuosheng's two 985 MWe BWRs were shut in July 2021 and March 2023, the first early because its spent-fuel pool was full. Its decommissioning permit awaits an environmental assessment, while Taiwan's government found in November 2025 that a restart is feasible, though fuel must first be offloaded to storage.
