China’s 3rd generation nuclear power plants were built on the AP1000, technology developed by Westinghouse Electric (USA).

According to the South China Morning Post, The number of third generation nuclear reactors based on Hoa Long 1 (Hualong One) technology approved or under construction in China now surpasses the number of AP1000 reactors.

China has 12 nuclear reactors using Hoa Long 1 technology under construction or pending approval. No new AP1000 nuclear reactors have been approved in more than a decade.

The nuclear furnace using US technology finally came into operation in 2018 in Zhejiang and Shandong provinces.

Hoa Long 1 is developed from ACP 1000 technology of China National Nuclear Corporation (CNNC), and ACPR 1000 technology of China Nuclear Power Corporation (CGN). Both technologies are built on technology from France.

Hoa Long 1 passed China’s national test in 2014, three years after the Fukushima nuclear disaster.

Many Chinese nuclear energy producers have adopted new technology. In particular, CNNC announced their 5th and 6th reactors in Phuc Thanh district, Fujian province, China, will apply the design of the water pressure reactor (PWR) of Hoa Long 1. This will be The first project to apply Hoa Long technology 1.

Construction of the two reactors began in 2015, and CNNC has poured nuclear fuel for the fifth facility in Phuc Thanh since early September. This facility will be operational by the end of 2021.

Four reactors approved last year and four other facilities approved on September 2 in Hainan and Zhejiang provinces will also apply Hainan 1 technology.

The World Nuclear Association (WNA) states that AP1000 was considered the leading technology for China’s 3rd generation nuclear plants, because of its passive safety and simplicity features. this. The AP1000’s modular structure and smaller components also allow for easier sourcing of the device in the country.
