According to World Nuclear, China is the worldwide leader in the field of molten salt reactor research, with a budget estimated at 500 million dollars. Researchers of the China Academy of Sciences/SINAP are working primarily on solid fuel MSR technology, as this is seen as a realistic first step.
However, SINAP has two streams of TMSR development – solid fuel (TRISO in pebbles or prisms/blocks) with a once-through fuel cycle, and liquid fuel (dissolved in fluoride coolant) with reprocessing and recycling. As the ‘T’ indicates, thorium fuels are considered for both streams.
A third stream of fast reactors to consume actinides from LWRs is planned. The aim is to develop both the thorium fuel cycle and non-electrical applications in a 20-30 year timeframe.
Chinese thorium MSR program
The TMSR-SF (solid fuel) stream has only partial utilization of thorium, relying on some breeding as with U-238, and needing fissile uranium input as well. It is optimized for high-temperature based hybrid nuclear energy applications. TRISO particles will be with both low-enriched uranium and thorium, separately.
The TMSR-LF (liquid fuel) stream claims full closed Th-U fuel cycle with breeding of U-233 and much better sustainability with thorium but greater technical difficulty. The TMSR-LF timeline is about ten years behind the SF one.
In December, three researchers of the Chinese Center for Thorium Molten Salt Energy System of the Shanghai Institute of Applied Physics, CAS will be visiting Delft and Petten. On December 5, they have kindly agreed to participate in a Meet&Greet organized by the Thorium MSR Foundation.
