The Ringhals nuclear power plant with four reactor blocks, one of which is a boiling water reactor and three pressurized water reactors , is located in the municipality of Varberg , in the southern Swedish province of Halland County .
The nuclear power plant is located on the Värö peninsula (Swedish: Väröhalvön) approx. 60 km south of Gothenburg . With a total installed capacity of 3560 MW , it is the most powerful Swedish nuclear power plant and generates around 24 TWh of electricity per year, which corresponds to 20% of Swedish electricity consumption.
Over 1000 people are employed at the Ringhals nuclear power plant. The operator of the power plant is Ringhals AB , 70.4% of which is owned by Vattenfall and 29.6% by Uniper . The operator announced that it would shut down Unit 1 in 2019 and Unit 2 early in 2020 (previously planned for 2025). Ultimately, however, Block 2 was initially shut down at the end of 2019, and Block 1 is to follow at the end of 2020.
Incidents
Incident in 2006
Shortly after midnight on November 14, 2006, there was an incident in Unit 3 of the nuclear power plant when a fire broke out in one of the two main transformers and then exploded. The reactor shut down quickly and no radioactivity was released, according to authorities . Unit 3 was built from 1972, went into operation in 1981 and has an output of 915 MW.
Operation subject to conditions and official supervision
On July 8, 2009, the Swedish nuclear regulatory authority SSM reported that 60 incidents had already been reported in the power plant in the first half of the year. Two were classified in the highest of three hazard categories. Safety deficiencies that have been complained about by the authorities since 2005 have not been remedied by the operator up to this point in time. The authority expressed fundamental concerns about the necessary security awareness in parts of the group. SSM is placing the power plant under stricter supervision. Vattenfall has to meet special requirements, including regular reporting. The reactor block 1, which was serviced at this point in time, may not be started up again for the time being.
Decommissioning due to serious safety deficiencies
On September 19, 2011, the media reported that in August 2011, as part of renovation work on reactor 2 after the last fire (spring 2011), remains of working material were found in the pipelines of the emergency cooling system. Workers had left them there during welding work in the 1980s. The power plant operator hadn't noticed this deficiency for 30 years. Due to this, all 4 reactors of the power plant were shut down with immediate effect. During the inspection, a sealing ring was also found in reactor 4 within the emergency cooling system. The shutdown applies until the operator has remedied the defects and can explain how this long-term safety risk could arise. On November 13, 2011, the media reported that a vacuum cleaner had been forgotten in reactor 2 during service work in spring. A short circuit in this caused a fire when the reactor was tested. The cleaning work is expected to be completed in December 2011.
Explosives found during routine inspection
During a routine check on June 20, 2012, "civilian explosives" (a fist-sized piece of dough) were found on a forklift truck that was supposed to drive into the innermost security area. Thereupon a search was started and the alertness in this and the other two Swedish nuclear power plants increased by one level.
Data of the reactor blocks
The Ringhals nuclear power plant has a total of four blocks :
| Reactor block | Reactor type | Net power | Gross output | start of building | Network synchronization | Commercial operation | Shutdown |
|---|---|---|---|---|---|---|---|
| Ring neck - 1 | Boiling water reactor | 855 MW | 887 MW | 02/01/1969 | 10/14/1974 | 01/01/1976 | Planned for 2020 |
| Ring neck - 2 | Pressurized water reactor | 867 MW | 917 MW | 10/01/1970 | 08/17/1974 | 05/01/1975 | 12/30/2019 |
| Ring neck - 3 | Pressurized water reactor | 985 MW | 1037 MW | 09/01/1972 | 07.09.1980 | 09/09/1981 | (approx. 2040) |
| Ring neck - 4 | Pressurized water reactor | 953 MW | 979 MW | 11/01/1973 | 06/23/1982 | 11/21/1983 | (approx. 2040) |
