The Takahama nuclear power plant ( Japanese 高 浜 発 電 所 , Takahama hatsudensho ), northwest of the town of Takahama in Fukui Prefecture , has four units , the oldest of which went into operation in 1974.
The operator of the nuclear power plant is the electricity supplier Kansai Denryoku (KEPCO or Kanden). The net output of the pressurized water reactors of the two older reactors is 780 MW and that of the two newer reactors is 830 MW.
Shutdowns and recommissioning
After the Fukushima nuclear disaster in March 2011, the nuclear power plant was shut down.
Blocks 1 and 2
Takahama 1 has been shut down since January 2011, Takahama 2 since November 2011.
Takahama-1 and -2 were granted a term extension from 40 to 60 years by the Japanese nuclear regulator NRA on June 20, 2016 , which had been requested by the operator KEPCO. They are the first reactors in Japan to which the NRA has granted this extension under the new regulations, and they are the two oldest Japanese reactors to go into operation after the Fukushima disaster. Their performance data are identical to the third oldest Japanese block, Mihama 3 , which is also to be restarted.
As of February 5, 2019, the operator anticipates a restart of Block 1 in July 2020 and Block 2 in March 2021.
Blocks 3 and 4
On February 18, 2015, the Japanese Atomic Energy Agency approved a restart. In April 2015, however, the district court of Fukui Prefecture prohibited the restart of reactors 3 and 4 in Takahama in the first instance following a complaint from residents: The plant operator, Kansai Electric, could not guarantee safety. In addition, the safety regulations are illogical and too loose, the earthquake risk is not assessed convincingly and a restart represents an "immediate danger" for the residents. Kansai Electric has filed a complaint with the Nagoya High Court, which was heard on November 14th.
On December 25, 2015, the Fukui District Court ruled that Takahama-3 and -4 can restart.
On January 29, 2016, Takahama-3 was restarted; MOX fuel assemblies are also to be used as fuel . On February 26, 2016, reactor 4 was restarted, but in the early morning of February 29, the reactor was automatically shut down due to faults in a generator and a transformer. Shortly before restarting, 34 liters of radioactive water had escaped from a cooling pipe in the reactor; the cause was an untightened bolt. This delayed the restart by one day. The Takahama-4 also uses MOX fuel assemblies.
On March 9, 2016, a court ordered the shutdown of the reactors or a ban on restarting them (one reactor had already been shut down due to a malfunction before the judge's verdict). The judges criticize the emergency plans and the technical equipment of the power plant. This reduced the number of reactors in network operation in Japan to 2.
On June 17, 2016, the district court in Otsu upheld its restart ban from March 2016 for the Takahama reactors, whereupon Kansai Electric announced that it would remove the fuel rods from reactors 3 & 4 and store them in the power plant's own decay pool.
On March 28, 2017, the Osaka Higher Court upheld Kansai Denryoku's appeal and lifted the ban imposed by the District Court. On May 22, 2017, power generation and transmission were restored at 2 p.m. in reactor 4. Reactor 3 was restarted on June 6, 2017.
Data of the reactor blocks
The Takahama Nuclear Power Plant has four blocks :
| Reactor block | Reactor type | net power |
gross power |
start of building | Network synchronization |
Commercialization of essential operation |
switching off processing |
|---|---|---|---|---|---|---|---|
| Takahama-1 | Pressurized water reactor | 780 MW | 826 MW | 04/25/1970 | 03/27/1974 | 11/14/1974 | since 1/2011 in long-term standstill |
| Takahama-2 | Pressurized water reactor | 780 MW | 826 MW | March 9, 1971 | January 17, 1975 | 11/14/1975 | in long-term standstill since 11/2011 |
| Takahama-3 | Pressurized water reactor | 830 MW | 870 MW | 12/12/1980 | 05/09/1984 | January 17, 1985 | (Planned for 2025) |
| Takahama-4 | Pressurized water reactor | 830 MW | 870 MW | 03/19/1981 | 11/01/1984 | 06/05/1985 | (Planned for 2025) |
Others
On January 15, 2007, the news agencies Kyodo News and AP reported a minor incident in Block 1. 370 liters of slightly radioactive water had leaked and four employees had been splashed. However, your health is unaffected. There are four Mitsubishi pressurized water reactors in Takahama .
