Hamaoka Nuclear Power Plant

The Hamaoka Nuclear Power Plant (Hamaoka Genshiryoku Hatsudensho, Hamaoka NPP) is a nuclear power plant located in Omaezaki city, Shizuoka Prefecture, Japan managed by the Chubu Electric Power Company. There are five units contained at a single site with a net area of 1.6 square kilometers (395 acres, about a fourth of fifth of a typical US plant). A sixth unit began construction on December 22, 2008. On completion, it is expected to replace Hamaoka-1 and Hamaoka-2.

The area is in a possible epicenter of future earthquakes according to predictions. In fact, a fault line runs straight through the site. Earthquake resistance is a very important aspect of this plant, and difficulties have been seen in previous events.

The plant showed stellar performance through the 1990s, however, problems that caused Unit 1 to be shut down from 2001 to present, and Unit 2 from 2005 to present significantly hurt the capacity factor figures in the recent history of the plant.

Unit 1 HPCI Rupture

On November 7, 2001 a valve in the HPCI system of Unit 1 ruptured during a Periodical-manual-startup-test. Since this is considered a part of the ECCS, the implications reach further the event itself, and drew into question the reliability of the emergency safety system. Unit 2 was also shut down for the purpose of investigating similar structures.

Unit 2 Steam Turbine Problems

Unit 5 Steam Turbine Problems

Too recent to cover the entire relevant time frame in the data above, on June 15, 2006 Unit 5 was shut down due to excessive turbine vibrations. It was discovered that a number of turbine vanes had actually completely broken off. In the turbine that failed, nearly all vanes showed fractures or cracking while the majority of the vanes of the other two low pressure turbines also showed problems. Fault for the problems were placed on Hitachi, the NSSS supplier.

Cattenom Nuclear Power Plant

The Cattenom Nuclear Power Station is located in Lorraine in the Cattenom commune, France on the Moselle River between Thionville (10 km upstream) and Trier (80 km downstream). It is close to the towns of Luxembourg (35 km) and Metz (40 km).

The site consists of 4 Pressurized Water Reactors that were all built between 1979 and 1991 and have an electric output of 1300 MW each. The plant is a relatively modern and large nuclear power station. In 2006 it produced the third most electricity (34 TWh) of the nuclear plants in France behind Gravelines (34.4 TWh) and Paluel (34.9 TWh).

The plant employs about 1200 regular employees and about 1000 more during outage times.

The station received its ISO 14001 certification in 2005, and should have its ISO 9001 and OHSAS 18001 in 2007.

The site uses 4 separate cooling towers which uses water from the Moselle. Additionally, a water reserve on site, Lake Mirgenbach, was created. In 1985 an artificial lake was also created in the Pierre-Percée valley in the Vosges Mountains. The creation of this lake has led to the flooding of the subterranean portions of Ouvrage Kobenbusch, part of the Maginot Line.

During the 2003 European heat wave it was permitted to dump the water used for cooling directly into the Moselle river. The heating of the water in these cases is limited to 1.5 degrees Celsius by prefectoral decree. Heating to 2.2 degrees was accidentally caused once.

  • In March 2001, the reactor building of Unit 3 was evacuated with 131 people, apparently due to a false alarm. No one was hurt and there were no radiation releases.

There were several incidents involving casualties, the latest being

  • On March 12, 2008, an employee was exposed to about 1/20 of the annual maximum allowed dose.
  • Eight workers were exposed to radiation in March 2005.

This list is not meant to be complete. The references include the official ASN list which names 88 events between march 2000 and march 2008.

The area around Cattenom has been found to be very low risk of earthquakes by the Ministry for Ecology.

Paluel Nuclear Power Plant

The Nuclear power station Paluel (French: Centrale nucléaire de Paluel) lies within the French town Paluel in Normandy in the Département Seine-Maritime. The nuclear power plant, which consists of four 1330 MWe class pressurized water reactors, is about 40 kilometers far away from the city of Dieppe and employs approx. 1,250 full time workers. The operator is the French company EDF. Water from the English Channel is used for cooling.

The installed total output of 5.528 GW makes it second largest nuclear power stations in France. By electrical output it is second place in France and seventh place worldwide. It feeds on average 32 billion kilowatt-hours into the public electricity grid every year.

In the past, there were problems with the cooling of the plant due to blockage of cooling water from the English Channel, which causes an automatic reactor trip.

The blockage has been caused in part by seasonally-present macroalgae, and EDF is pursuing possible solutions to prevent its entrainment with Gunderboom, Inc.

Gravelines Nuclear Power Station

The Gravelines Nuclear Power Plant is the fifth largest nuclear power station in the world. It is located in Nord, France, approximately 20 km (12 mi) from Dunkerque and Calais. Its cooling water comes from the North Sea. The plant houses 6 nuclear reactors. Two entered service in 1980, two in 1981, and two in 1985. The site employs 1680 regular employees.

The cooling water that carries waste heat from the plant is used by a local commune of aquafarmers who raise European seabass and gilt-head breams. The warm water helps them grow faster.

  • In August 2009, during the yearly exchanging of fuel bundles in Reactor-1, one bundle got stuck to the upper handling structure, stopping the operations and causing the evacuation and isolation of the reactor's building.
  • In 2007, the plant experienced four separate events that qualified as Level-1 on the INES Scale.
  • In 2006 when Unit-3 was taken offline for routine refueling. It was discovered that an electrical wire had not been plugged in correctly during the last outage in 2005. This too ranked Level-1 on the INES Scale.

Bruce Nuclear Generating Station

Bruce Nuclear Generating Station is a Canadian nuclear power station located on the eastern shore of Lake Huron, in the communities of Inverhuron and Tiverton, Ontario. The facility derives its name from Bruce County in which it is located, in the former Bruce Township.

The facility was constructed in stages between 1970 and 1987 by the provincial Crown corporation, Ontario Hydro. In April 1999 Ontario Hydro was split into 5 component Crown corporations with Ontario Power Generation (OPG) taking over all electrical generating stations. In June 2000, OPG entered into a long term lease agreement with private sector consortium Bruce Power to take over operation of the Bruce station. In May 2001, Bruce Power began operations.

The Bruce station is the largest nuclear facility in North America, and second largest in the world (after Kashiwazaki-Kariwa in Japan), comprising 8 CANDU nuclear reactors having a total output of 6,232 MW (net) and 7,276 MW (gross) when all units are online. Current output with 6 of the 8 reactors on line is 4,640 MW. The Bruce station has two 500 kV transmission lines going out of it to feed the major load centres in southern Ontario, in addition to three 230 kV lines serving the local area.

The reactors are as follows:

Bruce A
  • BRUCE A 1 (being refurbished)
  • BRUCE A 2 (being refurbished)
  • BRUCE A 3
  • BRUCE A 4

  • BRUCE B 5
  • BRUCE B 6
  • BRUCE B 7
  • BRUCE B 8

In the autumn of 2005, Bruce Power and the Government of Ontario committed to return units 1 and 2 to service, in order to help meet increasing energy demand in the province of Ontario. The project was originally estimated to cost $4.25 billion.

In 2006 and 2007, the restart project was judged to be the largest infrastructure project in Canada by ReNew Canada magazine. Estimated cost for the project later grew to $5.25 billion when Bruce Power decided to replace all 480 fuel channels in Unit 4, which will extend its working life to 2036, in line with the other 3 units of Bruce A. In 2008, due to difficulties developing the necessary robotics, the estimated cost of restarting Units 1 and 2 was raised between $400 and $700 million. The project, however, remained on schedule.

As part of a plan submitted to the Ontario Energy Board for approval, the Ontario Power Authority recommended building a new nuclear power station consisting of at least two reactors. The leading candidate is AECL's Advanced CANDU Reactor. Environmental assessments are currently underway both at Bruce and at Ontario Power Generation's Darlington Nuclear Generating Station.

Encompassed by the Bruce site is the shut-down Douglas Point reactor, an earlier version of the CANDU design.

Kashiwazaki-Kariwa Nuclear Power Plant

The Kashiwazaki-Kariwa Nuclear Power Plant is a large, modern (housing the world's first ABWR) nuclear power plant on a 4.2 square kilometer site including land in the towns of Kashiwazaki and Kariwa in the Niigata Prefecture, Japan on the coast of the Sea of Japan, from where it gets cooling water. The plant is owned and operated by The Tokyo Electric Power Company (TEPCO).

It is the largest nuclear generating station in the world by net electrical power rating. It was near the epicenter of the strongest earthquake to ever occur at a nuclear plant, the Mw 6.6 July 2007 Chūetsu offshore earthquake. This shook the plant beyond design basis and initiated an extended shutdown for inspection, which indicated that greater earthquake-proofing was needed before operation could be resumed.

The nuclear power plant was completely shut down for 21 months following the earthquake. On May 9, 2009, one unit (Unit 7) was restarted, after seismic upgrades. A second unit was restarted in August 2009, Unit 6.


There are seven units, which are all lined up along the coast line. Numbering starts at Unit 1 with the south-most unit up to Unit 4, then there is a large green space in between Unit 4 and 5, then it continues with Units 6 and 7, the newest of the reactors.

The power installation costs for units at this site well reflect the general trend in costs of nuclear plants. Capital costs increased through the 1980s but have become cheaper in modern times. The last two units were the first Advanced Boiling Water Reactors (ABWRs) ever built.

Such a large plant size has several economic advantages, one of these advantages is very little effect on net power production due to refueling outages of individual units. A smooth transition was seen in the power production history of the plant up through the time the last two units were built. Unfortunately, since completion the plant has seen two events that caused the entire plant to be shut down. The last of these two events is ongoing and data is not available yet, data for the rest of the plant's history is shown below:

2002 Scandal shut downs

The reactors at the KK plant were shut down one by one after the discovery of deliberate falsification of data. The first one was taken offline September 9, 2002 and the last one was taken offline January 27, 2003. The newest units, the more inherently safe ABWRs, were taken back online the quickest and suffered the smallest effect. Units 1, 2, and 3 on the other hand, generated no electricity whatsoever during the entire fiscal year of 2003.

All reactors continue to use low-enriched Uranium as the nuclear fuel, however, there have been plans drafted by Tepco to use MOX fuel in some of the reactors by the permission of the Japanese Atomic Energy Commission (JAEC). A public referendum in the Kariwa village in 2001 voted 53% against use of the new fuel. After the 2002 Tepco data fabrication scandals, the president at the time, Nobuya Minami, announced that plans to use the MOX fuel at the KK plant would be suspended indefinitely.
