Two more CAP1000 reactors planned for site in northeast of country
Construction has begun of Unit 2 at the Xudabu nuclear power station, bringing the number of plants under construction in China to 26.
China National Nuclear Corporation (CNNC) and state media said the first batch of concrete had been poured for the nuclear island of Unit 2 at Xudabu, in Liaoning Province, bordering North Korea in northeastern China, marking the official start of construction of the unit.
Xudabu-2 will be a 1,250 MW CAP1000 reactor, the Chinese version of the Westinghouse AP1000 pressurised water reactor unit. Construction of an identical unit, Xudabu-1, began in November 2023.
There are already two Russia-supplied VVER-1200 PWR units under construction at Xudabu, also written in English as Xudabao and Xudapu.* Those units are Xudabu-3 and -4.
The Xudabu project was originally expected to comprise of six CAP1000 plants, with Units 1 and 2 in the first phase. Site preparation began in November 2010, but plans changed with the construction of two VVER-1200 reactors for Units 3 and 4.
Two further CAP1000 reactors are planned for Units 5 and 6.
The construction of Xudabu-1 and -2 was approved by China’s State Council in July 2023.
The Xudabao nuclear station is owned by Liaoning Nuclear Power Company, in which CNNC holds a 70% stake with Datang International Power Generation Co holding 20% and State Development and Investment Corporation owning 10%. The general contractor is China Nuclear Power Engineering Company, a subsidiary of CNNC.
According to recent US Energy Information Administration analysis, China has added more than 34 GW of nuclear power capacity in the past 10 years, nearly tripling its nuclear capacity. Its 26 plants under construction are more than any other country.
China now has 56 commercial reactors in operation, the same number as France and second only to the US, which has 94. However, the nuclear share in the three countries differs widely. The nuclear share of total electricity production in the US is about 18%, while in China it is about 5% and in France about 62% – the highest in the world.
