TMSR-LF1 (Chinese: 液态燃料钍基熔盐实验堆 lit.: "liquid fuel thorium-based molten salt experimental reactor") is a 2 MWt molten salt reactor (MSR) prototype operating in northwest China.[location note]

The TMSR facility grew from the collaborative efforts of "nearly 100 domestic research institutions, universities and industrial companies", and is now "the world's only research platform dedicated to molten salt reactors and thorium-uranium fuel cycle studies".
