The Hamaoka nuclear power plant (Japanese浜 冈 原子 力 発 电 所, Hamaoka genshiryoku hatsudensho ) is a nuclear power plant in Japan. It is on the territory of the former municipality of Hamaoka ( on 1 April 2004 incorporated in Omaezaki ) in Shizuoka Prefecture located. The plant site covers about 1.6 km2 and is located about 173 kilometers from Tokyo. The owner is Chūbu Denryoku. The construction of the power plant has been greatly criticized, as it is located directly at a subduction zone, which is why earthquakes occur frequently in the area. The reactors used are boiling water reactors.
The reactors are cooled with seawater. This caused a problem in 2006, when huge amounts of jellyfish clogged the inlet. The power of two blocks had to be considerably reduced for a short time.
The system initially comprised four blocks and has expanded to five blocks from 2000. After the construction of the fourth block should actually be made no further extensions. So led the construction of the fifth block to the creation of the local anti - nuclear movement (English Society of Hamaoka Nuclear Power Plants Reviewing ), although the community is largely depend on the power plant.
At the time of starting operation of the reactor 5 in 2005, he was the most powerful in Asia and this year was also the second most productive in the world.
On 30 January 2009, the reactors were shut down 1 and 2. On May 5, 2011 - several weeks after the Fukushima nuclear disaster - the Japanese government has the temporary shutdown of the reactor units 4 and 5 and the non- commissioning of reactor 3, which is switched off for the purpose of maintenance arranged, were installed until additional safeguards against earthquakes and tsunamis.
Since the Fukushima nuclear disaster in Japan is saved massive power to precaution - one fears quakes or aftershocks - to switch off as many nuclear reactors. In August 2011, only 18 of the 54 Japanese commercial nuclear reactors were in operation.
Accidents
- On November 7, 2001, a line of the emergency cooling system of Unit 1 cause burst was possibly a hydrogen explosion.
- On 15 June 2006 had to be switched off 5 in the turbines because of suspicious vibrations block. An inspection revealed that a number of turbine blades exhibited damage. This was due to a design error. The problems with the turbines caused significant costs to their manufacturer Hitachi, which therefore had to report a significant decline in profits in 2007 for the previous year. The cost of the turbines are specified with 579 million U.S. dollars.
In the summer of 2011, the operator admitted that he was four years earlier instructed by NISA to manipulate the public debate on the safety of reactors, the uranium and plutonium use (see MOX fuel element). In addition, subject to the cooling pond of the Hamaoka power plant for 17 years wrecked fuel rods, of which no one knew how they could rescue them.
