北极星电力网China begins building pilot fast reactor
29 December 2017
Construction of China's 600 MWe demonstration fast reactor at Xiapu, Fujian province, has officially begun with the pouring of the first concrete for the reactor's basemat. The reactor is scheduled to begin commercial operation by 2023.

China National Nuclear Corporation (CNNC) announced today that civil nuclear construction had begun on the "landmark project for the development of China's nuclear industry".
Earlier this month, China Nuclear Industry 23 Construction Co Ltd signed the construction contract for installation of the nuclear island of the Xiapu fast reactor pilot project, following a tender process.
At a ceremony to mark the start of construction, CNNC chairman Wang Shoujun described the project as a major national nuclear science and technology project. He said it is of great significance for realising the closed nuclear fuel cycle, promoting the sustainable development of nuclear energy in China and promoting the development of the local economy.
Fast neutron reactors (FNRs) are seen as the main reactor technology for China, and CNNC expects the FNR to become predominant by mid-century. The country's research and development on fast neutron reactors started in 1964.
A 65 MWt fast neutron reactor - the Chinese Experimental Fast Reactor (CEFR) - near Beijing achieved criticality in July 2010, and was grid-connected a year later.
Based on this, a 600 MWe design - the CFR-600 - was developed by the China Institute of Atomic Energy. The Xiapu reactor will be a demonstration of that sodium-cooled pool-type fast reactor design. This will have an output of 1500 MW thermal power and 600 MW electric power. The reactor will use mixed-oxide (MOX) fuel with 100 GWd/t burnup, and will feature two coolant loops producing steam at 480°C. Later fuel will be metal with burnup of 100-120 GWd/t. The reactor will have active and passive shutdown systems and passive decay heat removal.
A commercial-scale unit - the CFR1000 - will have a capacity of 1000-1200 MWe. Subject to a 2020 decision to proceed, construction could start in December 2028, with operation from about 2034. That design will use metal fuel and 120-150 GWd/t burnup.

Permits issued for construction of new Chinese plant
15 October 2019
Construction licences have been issued for units 1 and 2 of the Zhangzhou nuclear power plant in China's Fujian province. The units were originally planned to be based on Westinghouse's AP1000 design, but will now feature domestically-designed Hualong One reactors.

China's Ministry of Ecology and Environment issued the construction licences on 9 October to CNNC-Guodian Zhangzhou Energy Company, the owner of Zhangzhou nuclear power project which was created by China National Nuclear Corporation (CNNC) (51%) and China Guodian Corporation (49%) in 2011. The licences are valid for 10 years.
The ministry said the submitted application documents complied with relevant national laws and nuclear safety regulations. It said the design principles and nuclear safety related activities at the Zhangzhou plant "meet the basic requirements of China's nuclear safety regulations, and the construction conditions are already in place".
The ministry has organised and supervised inspections of the on-site preparation of the nuclear island of Zhangzhou unit 1. It said the pouring of first concrete can take place once proposed "rectification requirements" have been completed and approved by the regulator.
"At present, your company is implementing rectification as required," the ministry said. "At the same time, the first tank of concrete of unit 2's nuclear island foundation is set as the control point." Once on-site preparation work for that unit's foundation has been inspected and approved, first concrete pouring can proceed, it said.
In May 2014, the local government gave approval for Phase I of the Zhangzhou plant, comprising two AP1000 units. The National Nuclear Safety Administration gave approval in December 2015 for the AP1000 units and confirmed site selection in October 2016. Construction of Phase I had originally been expected to start in May 2017. However, CNNC subsequently decided to use the Hualong One design instead. Two more Hualong One are planned for Phase II of the plant and a further two proposed for Phase III.
In late-2016, Germany's KSB Group was awarded a contract for six reactor coolant pumps for Zhangzhou 1 and 2, to be delivered in 2020 and 2021. In mid-2017, China Nuclear Industry No24 Construction Company won the contract for the nuclear island civil engineering. In February 2019, CNNC subsidiary China National Nuclear Power released its environmental impact assessment for public comment.
Hualong One reactors are currently under construction at Fuqing and Fangchenggang. Fuqing 5 and 6 are expected to start up in 2019 and 2020, as are Fangchenggang 3 and 4. The Hualong One promoted on the international market is called the HPR1000, two of which are under construction at Karachi in Pakistan.

CNNC unveils key safety technology

China National Nuclear Corp, the State-owned nuclear power company, released its domestically-developed high-safety nuclear power plant distributed control system platform on Thursday.
Known as the central nervous system of nuclear power plants, the nuclear advanced safety instrument and control platform, also called the Longlin system, plays an important role in ensuring nuclear projects' safety and stability and enables China to have a DCS with complete independent intellectual property rights, said the company.
Some of the key standards are in accordance with the international level, it said, while it will also help boost China's nuclear technology exports, it said.
Only a handful of developed countries have mastered the technology of the nuclear-grade DCS platform, which is critical for the safe shutdown and accident mitigation for reactors.
Analysts believe as the core technology of the systems is one of the key components of a nuclear power station, China must conduct original innovation.
It is believed the country will step up nuclear development with the implementation of the Longlin system, said Ye Qizhen, a member of the Chinese Academy of Engineering and also an expert on nuclear reactors and nuclear-power engineering.
According to CNNC, all of the design, verification and testing of the program is in accordance with the most advanced and strictest standards worldwide, while the system also uses advanced information security technology.
The Longlin system is a result of the company's more than 60 years of experience in integrating nuclear power engineering design, the research and development of the digital instrument control equipment and equipment manufacturing and supply.
The system could be applied in nuclear power plants, research reactors and small reactors, it said.
Yu Jianfeng, CNNC's chairman, said earlier that development of the nuclear industry over the past 60 years has proved that nuclear science and technology is strategically important. China must insist on independent innovation.
The company said it would pay a great deal of attention to the working conditions of scientists, an important factor in improving the company's core competitiveness.
"We will enable scientists undertaking major military projects and scientific and technological innovations to receive high salaries, and stimulate the creativity of talent to the greatest extent," he said.
