Aging Management of Ontario Power Generation's Dry Storage Containers for Used Fuel

Abstract

Ontario Power Generation uses Dry Storage Containers (DSCs) to store used CANDU fuel, following initial cooling in irradiated fuel bays. DSCs are subject to an aging management plan to ensure their 50-year design lives. This paper provides an overview of an aging management procedure developed by Ontario Power Generation's (OPG's) Nuclear Waste Management Division (NWMD) for managing its nuclear waste assets. Details of an aging management plan specific to the DSCs are highlighted, including the outcome of on-going inspections and activities that have been defined by the plan
