CNNC completes Nigerian MNSR conversion program
China National Nuclear Corporation (CNNC) finished its program of converting a highly enriched uranium (HEU)-fueled Miniature Neutron Source Reactor (MNSR) to a low enriched uranium (LEU)-fueled MNSR in Nigeria, on Dec 6.
The achievement is another example of CNNC delivering on the commitment made by Chinese President Xi Jinping at the Nuclear Security Summit, following the completion of the Ghana LEU-MNSR project.
It also marks China’s contribution to reducing and finally eliminating the civilian use of highly enriched uranium fuels, as well as to preventing international nuclear proliferation.
Reducing the enrichment of uranium fuels at MNSRs entails the replacement of HEU assemblies to LEU assemblies without any changes in the size of the reactor core.
The converted MNSR can keep the functions of the original one, but with an improved security performance and longer service life. China’s engagement in the conversion program demonstrates its resolution to fulfill its international obligations and help build an international nuclear security system.
CNNC is willing to continue to assist other countries to convert HEU-fueled MNSRs imported from China to LEU-fueled reactors –– boosting international nuclear security and preventing nuclear proliferation.
