The Incident Unfolds: Smoke and Initial Reports

Reports of a fire at the Maanshan Nuclear Power Plant sent shockwaves through Taiwan. Learn how the incident unfolded and what authorities said in response.

The Maanshan Nuclear Power Plant, located in Hengchun, Pingtung County, is Taiwan’s last operational nuclear facility, with its Unit 2 reactor slated for decommissioning by May 17, 2025, as part of the government’s “nuclear-free homeland” policy. This policy, championed by former President Tsai Ing-wen, aims to transition Taiwan to a reliance on renewable energy sources.

At approximately 11:30 AM local time (10:30 AM WIB) on March 6, 2025, reports began circulating of significant smoke rising from the plant. Local fire departments dispatched numerous units to the scene, and by midday, the Taiwan Power Company (Taipower) confirmed that the fire had broken out in a cooling tower situated roughly 50 meters from the nuclear power equipment.

Eyewitnesses described “large plumes of thick black smoke” emanating from the site, raising immediate fears of a potential nuclear safety incident. Social media quickly filled with images and videos of the smoke plume, amplifying public concern.

However, Taipower and the Taiwan Nuclear Safety Commission quickly moved to reassure the public. In a statement released shortly after the incident, Taipower emphasized that the fire was extinguished and posed “no safety concern,” noting that it did not impact electricity generation or the plant’s nuclear operations. The Nuclear Safety Commission echoed this, stating that all units were operating normally and that there were no signs of a radiation leak. These assurances were crucial in calming initial fears and preventing widespread panic.

Response and Containment: Firefighters on the Scene

A swift response from firefighters helped contain the blaze at the Maanshan Nuclear Power Plant. Discover how the fire was brought under control and what measures were taken to ensure safety.

The rapid response from local firefighters was instrumental in containing the blaze and preventing it from escalating into a more serious incident. Posts on X from TaiwanPlus News and other sources indicate that the situation was stabilized within hours, with the fire fully under control by the time of this report. The effectiveness of the firefighting efforts was widely praised on social media.

The cooling tower, a critical component for dissipating heat from the plant’s operations, appears to have been the sole point of ignition. While the exact cause remains under investigation, early speculation points to mechanical failure or an electrical fault—common culprits in industrial fires. Investigators are carefully examining the scene to determine the precise cause of the blaze.

Taipower’s assertion that the fire’s location—50 meters from nuclear equipment—prevented any direct threat to the reactors has been a key point of reassurance. Cooling towers, while essential, are physically separate from the reactor core and do not contain radioactive materials, reducing the risk of a radiological event. This physical separation is a critical safety feature designed to prevent fires and other incidents from affecting the nuclear reactors.

Nonetheless, the sight of smoke billowing from a nuclear facility inevitably evokes memories of past disasters like Fukushima, prompting a cautious but measured public response. Authorities are keenly aware of the sensitivity surrounding nuclear incidents and are taking extra precautions to ensure public safety and transparency.

Context: Taiwan's Nuclear Landscape - A Phase-Out in Progress

The fire at Maanshan occurs as Taiwan phases out nuclear power. Understand the implications for the island's energy grid and its reliance on renewable sources.

The Maanshan Nuclear Power Plant, operational since 1984, has been a cornerstone of Taiwan’s energy supply, though its role has diminished in recent years. The plant has two reactors, each capable of generating significant amounts of electricity.

With Unit 1 decommissioned in July 2024 and Unit 2 scheduled to shut down in May 2025, Taiwan is on the cusp of fulfilling former President Tsai Ing-wen’s pledge to phase out nuclear power by 2025. This policy shift, driven by public concerns over safety following the 2011 Fukushima disaster and a push toward renewable energy, has left Maanshan as the final holdout in a once-robust nuclear program. The decision to phase out nuclear power has been a subject of intense debate in Taiwan, with proponents arguing for increased safety and environmental protection, while opponents warn of potential energy shortages and economic consequences.

The timing of the fire is particularly significant. With Unit 2 currently undergoing its final months of operation, the incident raises questions about the maintenance and safety protocols in place during this transitional period. Are safety standards being maintained at the same level as when the plant was fully operational? This is a question that authorities will need to address to reassure the public.

Taiwan’s energy grid, already strained by the growing demands of its tech industry—most notably Taiwan Semiconductor Manufacturing Company (TSMC), which could account for 12.5% of the grid’s usage by year-end—faces additional scrutiny as nuclear power dwindles to zero. The reliance on renewable energy sources, such as solar and wind power, is increasing, but these sources are intermittent and may not be able to fully meet Taiwan's energy needs.
