Ghana Research Reactor-1

Ghana Research Reactor-1 (GHARR-1) na'urar bincike ce ta nukiliya da ke Accra, Ghana kuma ita ce kawai na'urar nukiliya a kasar. Cibiyar Nazarin Nukiliya ta Kasa ce ke sarrafa shi, wani sashi na Hukumar Makamashi ta Ghana. Reactor wani nau'i ne na kasuwanci na ƙirar Neutron Source Reactor (MNSR) na kasar Sin. Rashin wutar lantarki ya fara aiki a ranar 17 ga Disamba, 1994.

 Bayyanawa 
GHARR-1 mai sauƙin ruwa ne tare da matsakaicin ƙarfin zafi na 30 kW, matsakaicin yanayin zafi na 1012 s−1, da kuma matsakaicin saurin gudu na 1.2·1012 s−2. Ana amfani da Beryllium a matsayin mai nunawa kuma ana sanyaya reactor ta hanyar convection na halitta. Ana amfani da man fetur mai ƙarancin wadata, kodayake an tsara reactor ɗin da farko don 90.2% mai wadata uranium. Babban reactor yana da sandunan mai 347. 

Ana amfani da reactor galibi azaman kayan aikin bincike, gami da nazarin kunna neutron da gwaje-gwajen kimiyyar reactor. Bincike ya nuna cewa ana iya amfani da GHARR-1 don samar da radionuclide Technetium-99 a nan gaba. Hakanan ana amfani dashi don ilimin ɗaliban jami'a a Makarantar Kimiyya ta Nukiliya da Allied ta Jami'ar Ghana.

 Juyawa zuwa uranium mai wadata 
Ƙananan ƙirar neutron source reactor (MNSR) da farko ana aiki da shi tare da uranium mai wadata (HEU), yawanci 90% uranium-235 ko mafi girma. A shekara ta 2006, Hukumar Kula da Makamashi ta Atomic ta Duniya (IAEA) ta haɓaka aikin Bincike na Haɗin gwiwa (CRP) kuma a ƙarshe ƙungiyar aiki ta MNSR don daidaita juyawa zuwa man fetur mai ƙarancin uranium (LEU),  wanda aka bayyana a matsayin ƙasa da 20% Uranium-235. HEU yana da alaƙa da karuwar haɗarin yaduwa, saboda ana iya sauƙaƙe shi zuwa amfani mara zaman lafiya na makamashi na atomatik fiye da LEU. Hukumar Makamashi ta Atomic ta Ghana memba ne na ƙungiyar aiki ta MNSR, kuma ta sami nasarar sauya GHARR-1 zuwa ƙaramin man fetur.

Ghana was the first country outside of China to successfully convert their MNSR reactor to LEU. The HEU core was removed in August 2016 and the operation was completed in 2017. The original nuclear fuel was UAl4 with Al-303-1 cladding while the new LEU fuel is uranium dioxide at 13% enrichment with Zircaloy-4 cladding.
