Abstract :
AtomicEnergyofCanadaLimited(AECL)istheoriginaldeveloperoftheCANDU®reactor,oneofthethreemajorcommercialpowerreactordesignsnowusedthroughouttheworld.Forover60years,AECLhascontinuedtoevolvetheCANDUdesignfromtheCANDUprototypesinthe1950sand1960sthroughtothesecond-generationreactorsnowinoperation,includingtheGenerationII+CANDU6.Thenextphaseofthisevolution,theGenerationIII+AdvancedCANDUReactor™(ACR™),continuesthestrategyofbasingnextgenerationtechnologyonexistingCANDUreactors.BeyondtheACR,AECLisdevelopingtheGenerationIVCANDUSuperCriticalWaterReactor.
Owingtotheevolutionarynatureoftheseadvancedreactors,advancedtechnologyfromthedevelopmentprogramsisalsobeingappliedtooperatingCANDUplants,forbothrefurbishmentsandupgradingofexistingsystemsandcomponents.Inaddition,AECLisdevelopingadvancedtechnologythatcoverstheentirelifecycleoftheCANDUplant,includingwastemanagementanddecommissioning.Thus,AECLmaintainsstate-of-the-artexpertiseandtechnologytosupportbothoperatingandfutureCANDUplants.
