China Experimental Fast Reactor (CEFR)

The China Experimental Fast Reactor (CEFR)

The China Experimental Fast Reactor (CEFR) is a nuclear reactor located in China. It is a fast neutron reactor and serves as a prototype for future fast breeder reactors in China. The CEFR is part of China's efforts to develop advanced nuclear technology and to establish a closed nuclear fuel cycle.

Design and Development

The CEFR is a sodium-cooled fast reactor with a thermal power output of 65 MW and an electrical output of 20 MW. It was designed to test the technology and components necessary for larger fast reactors. The reactor uses mixed oxide fuel (MOX), which is a blend of plutonium and uranium.

The development of the CEFR began in the 1990s, with construction starting in 2000. The reactor achieved its first criticality in 2010 and was connected to the grid in 2011. The CEFR is operated by the China Institute of Atomic Energy (CIAE).

Objectives

The primary objectives of the CEFR are to:

• Demonstrate the feasibility of fast reactor technology in China.
• Provide a platform for research and development of fast reactor technology.
• Test the performance of sodium coolant systems and other components.
• Contribute to the development of a closed nuclear fuel cycle by using MOX fuel.

Significance

The CEFR is significant for several reasons:

• It represents China's commitment to developing advanced nuclear technology.
• It is a step towards achieving energy security and reducing reliance on fossil fuels.
• It provides valuable data and experience for the design and construction of future fast reactors, such as the planned China Fast Reactor 600 (CFR-600).

Challenges

Operating a fast reactor like the CEFR presents several challenges:

• Managing the sodium coolant, which is highly reactive with water and air.
• Ensuring the safety and reliability of the reactor systems.
• Developing and handling MOX fuel, which contains plutonium.

Future Prospects

The success of the CEFR is expected to pave the way for larger commercial fast reactors in China. The experience gained from the CEFR will inform the design and operation of the CFR-600 and other future reactors. These reactors are part of China's strategy to establish a sustainable and secure energy supply.
