The CFR-600 is a sodium-cooled pool-type fast-neutron nuclear reactor under construction in Xiapu County, Fujian province, China, on Changbiao Island.[1][2] It is a generation IV demonstration project by the China National Nuclear Corporation (CNNC). The project is also known as Xiapu fast reactor pilot project.[2] Construction of the reactor started in late 2017. These reactors are expected to be connected to the grid in 2023 and 2025.[3] The reactor will have an output of 1500 MWth thermal power and 600 MW electric power.[1][2] The fuel will be supplied by TVEL, subsidiary of Rosatom, according to the agreement signed in 2019.

The CFR-600 is part of the Chinese plan to reach a closed nuclear fuel cycle. Fast neutron reactors are considered the main technology in the future for nuclear power in China.

A larger commercial-scale reactor, the CFR-1000, is also planned.[2]

On the same site, the building of a second 600 MW fast reactor CFR-600 was started in December 2020[4] and four 1000 MW CAP1000 are proposed.[5]

There are series concerns from the West that these breeder reactors will be used to produce weapon grade plutonium for nuclear weapon manufacturing purposes. [6]

AlJazeera reported in 2021 that the reactors are controversial because they will produce weapons-grade plutonium, so likely have a dual military and civilian use, and China has stopped annual voluntary declarations to the International Atomic Energy Agency [IAEA] on its stocks of plutonium.[10]
