The Tomari Nuclear Power Plant ( Japanese 泊 発 電 所 , Tomari hatsudensho ), located near Tomari in Furuu County in Hokkaidō Prefecture , is the only nuclear power plant on Hokkaidō . About 5.5 million people live on the island. The facility on its 1.35 km 2 site belongs to Hokkaidō Denryoku .

The plant has three nuclear reactors from Mitsubishi .

Incidents and accidents

Electricity production in units 1 and 2 of the nuclear power plant from commissioning until 2007

In 1995, some workers were seriously injured when a tank of radioactive waste caught fire.

On August 17, 2000, a worker in the radioactive waste area fell into a receptacle. He died later in hospital. Despite decontamination , the worker was still wearing contaminated clothing in the ambulance, neither ambulance drivers nor clinic staff were informed and therefore unprepared.

In September 2003, cooling water leaked from the primary circuit of Tomari-2.

In May 2005, some people were arrested after climbing over the 2.5-meter high security fence to cut bamboo shoots.

In June 2005, a computer virus leaked plans and data from a Mitsubishi employee's PC to the Internet. This also included plans for the Tomari and Sendai nuclear power plants, and something similar happened to an employee of the Nuclear and Industrial Safety Agency , the Japanese nuclear supervisory authority.

To Fukushima

Since the nuclear disaster in Fukushima, the Japanese have been saving massive amounts of electricity in order to be able to shut down as many nuclear reactors as possible as a precaution - there are fears of further earthquakes.

Reactor 1 in Tomari was on 20 April 2011 due to "regular maintenance" (scheduled maintenance shut down); Reactor 2 on August 26, 2011.

After the penultimate nuclear reactor that was still running went offline as planned in March 2012, only one nuclear reactor was still in operation in Japan: Reactor 3 at the Tomari NPP.

On May 5, 2012, Tomari-3 was the last nuclear reactor in Japan to go offline for several months after the nuclear disaster in Fukushima. For the first time in 42 years, Japan had to do without nuclear energy entirely.

On July 8, 2013, the operator applied to the NRA supervisory authority to restart the Tomari-1, -2 and -3 units.

During the ongoing inspection, the Japanese nuclear regulatory authority determined that the emergency cooling system at the Tomari nuclear power plant did not meet the new requirements. The Hokkaido Electric group therefore announced additional extensive measures. Due to these circumstances, the commissioning of the power plant is to be "significantly" delayed.

In September 2018, an earthquake interrupted the external power supply, so the cooling pool had to be cooled with diesel- powered emergency power generators. Radioactivity was not released.

The Reuters news agency rated a restart of all three blocks of the plant in 2014 as "likely". At the end of October 2018, she found that a restart of Block 3 was "uncertain" and of Blocks 1 and 2 "unlikely". Hokkaidō Denryoku states that they invested around 200 billion yen (approx. 1.75 billion US dollars) in converting the power plant. A tsunami barrier was built, which may have been damaged after the last earthquake and must be replaced. In addition, investigations by the Japanese nuclear regulator focus on a possible active fault that runs directly under the reactor buildings. It cannot be ruled out that the earthquake of September 2018 will influence the decision of the nuclear regulator with regard to the reopening of the plant.

Data of the reactor blocks

The Tomari Nuclear Power Plant has three blocks :

Reactor block Reactor type net
