| Unit | Type | First Criticality | Electric Power |
|---|---|---|---|
| Tomari - 1 | PWR | June 6, 1989 | 579 MW |
| Tomari - 2 | PWR | April 12, 1991 | 579 MW |

[edit] Performance
The annual load factors for both existing units are shown below.
This shows no loss in capacity for any year that is highly noticeable in the performance figures.
[edit] Location
There is a straight shot from the plant to the ocean with no obstacles in between.
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.
[edit] Events
- In 2000, a worker fell into a sump tank in the chemical control system of the plant. The worker received a high radiation dose and died in the hospital later.[1]
- In September 2003 there was a leak in the steam generator causing about 140 Litters of primary coolant to leak.[2]
- In May 2005 there was a trespassing event where someone crossed the fence into the property. Some people had apparently been gathering bamboo sticks as a part of a part time job and when discovered, 24 arrests were made. There were all questioned due to strong concerns about terrorism at the plant.
- In July 2007, there were three separate fires related to the new unit that was under construction. Electrical wiring had apparently been cut and foul play was expected. Coming just days after more serious earthquake caused events at the Kashiwazaki-Kariwa plant, it dealt a further blow to Japan's nuclear power industry.[4]
- On September 29, 2007, Kazutoshi Michinaka reported that there was no radiation leakage, and no one was hurt in the small fire at a half-built reactor at Tomari Nuclear Power Plant, Hokkaidō, Japan At least 7 arson cases have been reported at the construction site this year. [5]
