Fugen Nuclear Power Plant: Introduction

Mon, 16 Feb 2026 00:00:00 GMT

They named the reactor after a bodhisattva. Fugen Bosatsu -- Samantabhadra in Sanskrit -- is the Buddhist embodiment of universal compassion, traditionally depicted riding an elephant, the idea being that only bodhisattva-like wisdom could tame the enormous power of the atom for the benefit of humankind. Its neighbor down the Tsuruga Peninsula was named Monju, after the bodhisattva of wisdom, who rides a lion. The spiritual ambition embedded in those names makes the actual history of the Fugen Nuclear Power Plant all the more sobering. Built on the coast of Wakasa Bay in Fukui Prefecture, Fugen operated for 24 years, set a world record, suffered a pattern of concealed incidents, and now sits in slow-motion disassembly -- a monument to both the promise and the complications of nuclear technology.

The record was not clean. In April 1997, a tritium leak occurred at the facility. Management waited 30 hours before reporting it to the authorities. The ensuing investigation revealed that this was not an isolated lapse -- 11 similar incidents had gone unreported. Five managers o...

Fugen Nuclear Power Plant: Dismantling the Dream

Decommissioning began formally in February 2008, when the Japan Atomic Energy Agency reorganized the facility into the Fugen Decommissioning Engineering Center. The process started with the least contaminated components -- turbine systems and auxiliary equipment -- while research...

Fugen Nuclear Power Plant: The Peninsula of Reactors
