The Tianwan nuclear power plant ( Chinese 田灣核電站 / 田湾核电站 , Pinyin Tiánwān Hédiànzhàn ) (formerly Lianyungang ) is located directly on the Yellow Sea around 30 kilometers east of the city of Lianyungang in Tianwan, Lianyun district . It is a Russian-Chinese joint project.

The nuclear power plant has so far consisted of four blocks with a total of 4,070 MW of net electrical output. The first two blocks have been in regular operation since 2007, blocks 3 and 4 since 2018. Two further blocks have been under construction since 2015 and 2016 respectively.

history

The power plant goes back to a Sino-Russian cooperation agreement from 1992. The planning consists of three phases. In phases 1 and 2, two reactors each will be built. Four reactors are to be built in phase 3. Phase 1 ended in 2007 with the commercial commissioning of the two reactors and phase 2 was completed in 2018. Reactors 5 to 6 are under construction.

The Fukushima nuclear disaster (since March 2011) made the population aware that nuclear power plants directly on the coast are not tsunami- safe. At times it was unclear whether the other two would still be built. However, the contracts for this were signed in June 2018.

Construction phase 1 began with construction of the Tianwan-1 reactor on October 20, 1999, and for the second unit on October 20, 2000. Unit 1 became critical for the first time on December 20, 2005 . It was first synchronized with the network on May 12, 2006. Commercial power operation began on May 17, 2007. The second reactor was first synchronized with the power grid on May 14, 2007. It went into commercial operation on August 16, 2007. The cost of Phase 1 was $ 3.2 billion.

Phase 2 was scheduled to begin in 2008. In this step two more reactors of the type WWER-1000/428 should be built as AES-91. Atomstroiexport expected the signing of the framework agreement for the construction of the two units in a very short time. After the end of the one-year Chinese moratorium due to the reactor disaster in Fukushima, construction of the third reactor began in December 2012. The first fuel assemblies were loaded in mid-August 2017, and at the end of September the reactor achieved a self-sustaining chain reaction for the first time. Tianwan-3 with a net output of 1,045 megawatts was connected to the power grid for the first time on December 30, 2017, and went into commercial operation on February 14, 2018. It is the 38th nuclear power plant in the country.

In phase 3, four more reactors of the Russian type WWER-1000/428 were originally to be built in the form of the AES-91. However, in December 2015, CNNC began building a domestic design for Blocks 5 and 6 . Units 7 and 8 will be Russian pressurized water reactors like the first four units, but from the larger successor type VVER-1200 .

Once all 8 reactors have been implemented, the Tianwan nuclear power plant would be the most powerful nuclear power plant in the world with over 8 GW of net electrical output.

Reactor model

All four blocks located in the commercial operation have VVER - pressurized water reactors , which of Atomstroyexport were delivered. The first two together cost around $ 3.3 billion. This version of a Russian standard reactor type VVER-1000/392 specially adapted for China is called VVER-1000/428. This reactor has been equipped with western control systems and received additional protection against earthquakes.

Disruptions

On August 26, 2008, a Ukraine-made transformer for the first reactor block exploded on the site, causing it to be shut down immediately. The fire was extinguished after five hours. One person was injured. The incident in the nuclear power plant was initially hushed up and only announced in September 2008.

Data of the reactor blocks

The world's first nuclear power plant of the type AES-91 has four blocks , but it is to have up to four more:
