Ninety-six new AREVA fuel assemblies have been unpacked, inspected and loaded in Calvert Cliffs’ spent fuel pool in preparation for the 2018 Unit 1 refueling outage. The Calvert Cliffs reactors are refueled every 24 months during a planned refueling outage. These outages help ensure the unit runs safely and provides consistent, reliable power to the region for another two-year cycle.
While the unit is offline, technicians replace nearly one-third of the reactor’s fuel and perform more than 10,000 inspections, tests, maintenance activities and modifications. Many of the tasks performed during the outage cannot be accomplished while the unit is online.
To support the refueling outage each year, approximately 2,000 additional workers travel to Calvert for several weeks, filling nearby hotels to capacity and increasing foot traffic in restaurants and shops.
