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.
New to decommissioning? The nuclear decommissioning market in 2026: size, players, pipeline
Current state
| Status | Shut down |
| Country | Taiwan |
| Location | Wanli, New Taipei |
| Site | Kuosheng (Second NPP) |
| Units | Unit 1, Unit 2 |
| Unit count | 2 |
| Reactor types | BWR |
| Owner / licensee | Taiwan Power Company (Taipower) |
| Strategy | Immediate dismantling |
| Final shutdown | 2023-03-14 |
| Spent fuel | Full pool forced Unit 1's early shutdown; fuel remains in the reactor and must be moved to dry storage. |
| Notable issue | Restart deemed feasible by the economy ministry; decommissioning permit pending EIA approval. |
Notes
Could move to "Restart planned" if Taipower files a Kuosheng restart plan; restarts tracker may cover it. Capacity 985 MWe per unit per NEI.
Timeline
- 2021-07 — Kuosheng 1 was permanently shut down early due to lack of spent-fuel pool space. (source)
- 2023-03-14 — Kuosheng 2 was permanently shut down. (source)
- 2025-11 — The economy ministry approved a Taipower report finding a Kuosheng restart feasible. (source)
The timeline is append-only: corrections are added as new entries. Stated targets appear in the current-state table, never as milestones.
