The Hamaoka Nuclear Power Plant ( Japanese 浜 岡 原子 力 発 電 所 , Hamaoka genshiryoku hatsudensho ) is located on the territory of the former Hamaoka Municipality ( incorporated in Omaezaki on April 1, 2004 ) in Shizuoka Prefecture . The power plant area covers around 1.6 km² and is around 173 kilometers from Tokyo. The owner is Chūbu Denryoku . The construction of the power plant has been heavily criticized as it is located right next to a subduction zone , which is why earthquakes in the area are frequent. The reactors used are boiling water reactors .
The reactors are cooled with sea water. This created a problem in 2006 when huge numbers of jellyfish clogged the inlet. The output of two blocks had to be reduced significantly for a short time.
The system initially comprised four blocks and was expanded to five blocks from 2000. After building the fourth block, no further extensions should actually be made. The construction of the fifth block led to the establishment of the local anti-nuclear energy movement ( Society of Reviewing Hamaoka Nuclear Power Plants ), although the community is heavily dependent on the power plant.
When Reactor 5 went into operation in 2005, it was the most powerful in Asia and also the second most productive in the world that year.
On January 30, 2009, reactor units 1 and 2 were shut down. On May 5, 2011 - a few weeks after the Fukushima nuclear disaster - the Japanese government ordered the temporary shutdown of reactor units 4 and 5 and the non-commissioning of reactor 3, which had been shut down for maintenance work, until additional earthquake and tsunami precautions were taken .
The Hamaoka nuclear power plant was completely shut down on May 14, 2011 and has been idle since then (as of 2015).
Since the nuclear disaster in Fukushima, Japan has 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 or aftershocks. As of August 2011, only 18 of the 54 commercial Japanese nuclear reactors were still in operation. The current state of affairs (2014) is that almost all of Japan's NPP park has been shut down. However, after retrofitting efforts, various operators have applied for a restart. The current Japanese Abe government does not want to completely do without nuclear power in the long term.
Accidents
- On November 7, 2001, a pipe in the emergency cooling system in Unit 1 burst. The cause may have been a hydrogen explosion.
- On June 15, 2006, Unit 5 had to be shut down due to suspicious vibrations in the turbines. An inspection revealed that numerous turbine blades were damaged. The cause for this was a design flaw. The problems with the turbines resulted in significant costs for their manufacturer Hitachi , which therefore had to report a significant drop in profits in 2007 for the previous year. The cost of the turbines is given as 579 million US dollars.
In the summer of 2011, the operator admitted that four years earlier it had been ordered by NISA to manipulate the public discussion about the safety of reactors that use uranium and plutonium (see MOX fuel assembly ). In addition, fuel rods have been in the decay basins of the Hamaoka power plant for 17 years and no one knows how to recover them.
Current status and future of the power plant
Unit 3 has been idle since November 2010, units 4 and 5 since May 2011. The future of the plant is uncertain. A 22-meter-high reinforced concrete tsunami barrier was built around the entire system on the lake side; the cost of the retrofitting sometimes amounts to approx. 400 billion yen (approx. 3.5 billion US dollars). In February 2014, the operator applied for Unit 4 to be reopened, and for Unit 3 in June 2015. Processing of the applications is barely progressing, as the earthquake and tsunami safety of the power plant has not yet been assessed. No application would be submitted for block 5. According to the operator, salt water penetrated the reactor block in 2011, and there is no assessment of whether the block is still repairable or whether Chūbu Denryoku is even considering such a repair. The planned restart of units 3 and 4 is met with great protest in the region due to the location of the plant in a highly seismically active area; the governor of the prefecture has announced that he will not agree to a restart within his term of office, which will last until 2021.
