TMSR-LF1 (液态燃料钍基熔盐实验堆; "liquid fuel thorium-based molten salt experimental reactor") is a 2 MWt prototype molten salt reactor (MSR) currently under construction in an industrial park in Minqin County, in the province of Gansu in northwest China. Construction is expected to finish in August 2021, with a test run as early as September.
In January 2011, the Chinese Academy of Sciences began the TMSR research and development project to create reactors which, among other advances, will be air-cooled. The liquid fuel ("LF") design is descended from the 1960s Molten-Salt Reactor Experiment at Oak Ridge National Laboratory in the US.
Scaled-up commercial reactors based on the LF1 are likely in the 2030s in central and western China, and may also be built outside China in Belt and Road Initiative nations; as low-carbon power plants, they would help to achieve the Chinese government's 2060 goal of carbon neutrality.
As per official documentation, i.e. Environmental Impact Report (Operation Phase) (in Chinese; see section 2.1.1) the TMSR-LF1 site is located at 38°57'31" N, 102°36'55" E. However, due to the China GPS shift problem, the location using Western GPS coordinates is about 38°57'36" N, 102°36'43" E (approximately a third of a kilometer offset).
