havealreadyproventheirabilitytointegrateandcomplywiththeneedsofvariousgroupswithinthe commercial, research and development,energyandservicesectors.
Today, there are ten operating RRs across theAfrican continent. These reactors cover a widepowerrange,startingwith30kWupto22MW.Several common designs are represented,including the General Atomics Training,Research, Isotopes (TRIGA) model and theMiniature Neutron Source Reactor (MNSR), butthere are other unique designs represented aswell, as shown in Table 1. Whereas Morocco’snewMA-R1reactorcandemonstratethemultipleuses of neutron activation analysis (NAA) andAlgeria’s facilities provide expertise in neutronstudies of various materials, the versatility ofSouthAfrica’sSAFARI-1,asoneofthefivemainproducers of the radioisotope molybdenum-99(Mo-99) and a leader in neutron transmutationdopingofsilicon,andthespecialitiesofNigeria’sCentre for Energy Research and Training aswell as Ghana’s National Nuclear ResearchInstitute comprise comprehensive units forresearch, engineering and academic groups.Taken together,cooperationamong thenuclearresearch facilities of Africa allows for theeffective optimization of their capabilities whileharmonizing research, operation and safetypractices.Suchprogrammeshavethepotentialto facilitate commercially viable radioisotopeproduction,moreaccurateandbroaderresearchendeavours, and more enriching and valuabletraining curricula. Efforts in Africa to integratehigher education in science can be seen withthe increasingnumberofMScandPhD thesesthathavebeencompletedatleastinpartthroughresearchofferedbythesereactors.
With their geographical locations andcapabilities, Africa’s RRs are well positioned tofurther socioeconomic development. Increasesinthestandardof livingofagivenareatendtohave a direct correlation with increased energydemands. Increasingly, countries seek nuclear

South Africa is currently thesoleAfricanStatewithanuclearpowerstation,and ithas intentions forgreatercapacity in thefuture.SomeotherMemberStateswithRRs,e.g.Algeria,Egypt,Ghana,Morocco,andNigeria,areseeking to use their experience as a steppingstoneforafuturenuclearpowerprogrammefortheirpeopleinordertotakeadvantageofAfrica’svast uranium resources.

1. Technical Characteristics The Nigeria Miniature Neutron Source Reactor, named NigeriaResearch Reactor-1 (NIRR-1), is a low power research reactorwith a nominal thermal power of 31 kW and a maximum flux of1×1012cm–2s–1initsinnerirradiationsites.Itisasmall,compactandsafe reactor thatemploysHEUas the fuel, lightwateras themoderator/coolant,andberylliumasthereflector.ThisMNSRwasdesigned for use in universities, hospitals and research institutesmainlyforNAA,limitedproductionofshort-livedradioisotopesandtraining.
The reactor is a pool type owned by the Nigeria Atomic EnergyCommission with the assistance of the IAEA. It is located at theCentre forEnergyResearchandTraining (CERT)atAhmaduBelloUniversityinZaria,Nigeria.
Technical features:• 30kWthermalpower.• Neutronflux:~1012cm–2s–1.• Onecentralcontrolrodusedforregulatingpowerlevel,

2. Products and Services ThereactorisdesignedmainlyforNAA,andthisversatileanalyticaltechnique, with the multichannel analyser computer system, isbeingusedinsupportofmanyresearch,commercialirradiationandteaching projects. Auxiliary systems such as pneumatic transfersystems provide for additional NAA capabilities. One, known astype A, is suitable for irradiation for medium and long periods.TypeB,amultifunctioncapsuletransfersystem,iscoupledtofourirradiation tubes. The reactor is also used for training in nuclearphysicsandnuclearengineeringcoursesatCERTsuchasreactorstatics, reactor dynamics, thermal hydraulics, health physics andradiologicalprotection.
