Six reactor license expiries ended with Taiwan’s last operating reactor shut in May 2025.
Taiwan’s nuclear timeline compresses a seven-year retirement sequence into one visual. The final Maanshan Unit 2 shutdown in May 2025 ended commercial nuclear operation after the earlier Chinshan, Kuosheng and Maanshan retirements. The sequence gives context to why nuclear’s power-generation share had already fallen to about 4% in 2024.

This is a reactor-retirement timeline, not a full annual generation series. Nuclear generation did not instantly reach zero in calendar 2025 because Maanshan Unit 2 operated until May.
Milestones use Nuclear Safety Commission license-expiry dates for Chinshan, Kuosheng and Maanshan units. The 2024 generation-share context comes from Energy Administration/EIA summaries of final generation data. Timeline dates are rounded to month or year for SVG readability.
