The conversion of Miniature Neutron Source Reactors (MNSRs) from high-enriched uranium (HEU) to low-enriched uranium (LEU) is an important step for non-proliferation. Ghana's MNSR, an MNSR running on HEU designed and manufactured by the China Institute of Atomic Energy (CIAE) in 1994, is the only nuclear reactor in the country, and has made important contributions to the application and development of nuclear technology and personnel training in #Ghana. Between 2015 and 2017, #CNNC actively responded to the Nuclear Non-Proliferation Initiative. With technical support provided by the CIAE for the conversion to LEU, and under the agreement of the CIAE with the Argonne National Laboratory (ANL) of the U.S. on LEU fuel design, processing and zero power testing, the conversion of Ghana's MNSR to low-enriched uranium was implemented.

The conversion of Ghana's MNSR to low-enriched uranium is the first international nuclear engineering project in which China assisted another country in carrying out a low-enriched uranium conversion for an MNSR. The completion of the project marked the complete success of the "Ghana Model" proposed by Chinese President Xi Jinping at the Nuclear Security Summit in Washington D.C., the U.S., in 2016. It made contributions to the civilian HEU reduction and eventual elimination, provided strong technical support for other conversion projects of MNSRs to low-enriched uranium, and offered important experience to the international community in terms of nuclear non-proliferation and nuclear security.
