The Tomari Nuclear Power Plant (泊発電所 Tomari hatsudensho, Tomari NPP) is the only nuclear power plant in Hokkaidō, Japan. It is located in the town of Tomari in the Furuu District and is managed by the Hokkaido Electric Power Company.[1] All of the reactors are Mitsubishi designs. The plant site totals 1,350,000 m2 (334 acres), with an additional 70,000 m2 of reclaimed land.[2][3]

Location

The plant was originally going to be located on an island and be named the Kyowa-Tomari NPP, but there was a change in plans and the location and name was changed.

History

Stress-tests

Seismic research in 2011 showed that the March 11th quake was caused by the simultaneous movement of multiple active faults at the coast of the Pacific Ocean in northern Japan and that much bigger earthquakes could be triggered than the plants were built to withstand. In February, the Tokai Daini Plant in Ibaraki Prefecture and the Tomari power facility in Hokkaido, said that they could not rule out the possibility that the plants were vulnerable. Other nuclear power stations declared that the active faults near their nuclear plants would not move at the same time, and even if it did happen, the impact would be limited. NISA is to look into the evaluation of active faults done by the plants.[16][17]

Performance

The annual load factors for both existing units are shown in this chart:

This shows no loss in capacity for any year that is highly noticeable in the performance figures.
