The China Mianyang Research Reactor (CMRR) with the power of 20 MW is located in the NP campus of Institute of Nuclear Physics and Chemistry, Mianyang city, Sichuan Province. It was open to users officially from 2012, including the thermal and cold neutron halls. The liquid hydrogen cold neutron source began to work from September 2013. The measured thermal and cold fluxes for neutron scattering experiments are 2.4×1014 n/cm2·s and 109 n/cm2·s, respectively.

CMRR is devoted to both fundamental and applied research. Its spectrometer layout is shown in the figure. In the first phase, eight neutron scattering instruments have been installed and start operation from the middle of 2014. Four thermal neutron instruments were installed in the reactor hall: a high resolution neutron diffractometer (HRND), a residual stress neutron diffractometer (RSND), a thermal neutron radiography station (TNR) and a high pressure neutron diffractometer (HPDC). Four cold neutron instruments were installed in the guide hall: a small-angle neutron spectrometer (SANS), a time-of-flight and polarized neutron reflectometer (TPNR), a cold-neutron triple-axis spectrometer (CTAS) and a cold neutron radiography station (CNR).
