Fugen Nuclear Power Plant

Fugen Nuclear Power Plant

Fugen ふげん (Fugen?) is a prototype Japanese nuclear test reactor that is currently shut down and awaiting decommission. It is located in Myōjin-chō, in the city of Tsuruga, Fukui. The design is an Advanced Thermal Reactor, which is a product of Japan. The name "Fugen" is derived from Fugen Bosatsu (Samantabhadra), a Buddhist deity.

The reactor was the first in the world to use a full MOX fuel core. It had 772 assemblies, the most in the world. It has received the title of a historic landmark from the American Nuclear Society.

The design boils ordinary water like a boiling water reactor (BWR) but uses heavy water as a moderator as in a CANDU reactor. The electrical output was 165 MW and the thermal output was 557 MW. On March 3, 2005, the reactor stopped operations.

  • Core temperature: 300 °C
  • Pellet centerline temperature: 2200 °C
  • Fuel conversion time: 6 months

The plant is located on a site that covers 267,694 m2 (66 acres); buildings occupy 7,762 m2 (1.9 acres), and it has 46,488 m2 of floor space. It employed 256 workers.

Famous quotes containing the words nuclear, power and/or plant:

    The emotional security and political stability in this country entitle us to be a nuclear power.
    Ronald, Sir Mason (b. 1930)

    ‘Tis a sort of duty to be rich, that it may be in one’s power to do good, riches being another word for power.
    Mary Wortley, Lady Montagu (1689–1762)

    I grow savager and savager every day, as if fed on raw meat, and my tameness is only the repose of untamableness. I dream of looking abroad summer and winter, with free gaze, from some mountain-side,... to be nature looking into nature with such easy sympathy as the blue-eyed grass in the meadow looks in the face of the sky. From some such recess I would put forth sublime thoughts daily, as the plant puts forth leaves.
    Henry David Thoreau (1817–1862)
