Constellation works to restore Calvert Cliffs nuclear unit

LUSBY — Constellation Energy Nuclear Group says inspections are underway to determine when it can restart a nuclear reactor at its Calvert Cliffs plant that shut down during Hurricane Irene.

One of the two reactors at the plant shutdown automatically when a piece of aluminum siding was blown into a transformer. CENG said Monday that two representatives from the federal Nuclear Regulatory Commission are at the site and inspections of the transformer are underway.

The company said it is working through procedures and outage protocols to determine when Unit 1 will be brought back online. Unit 2 was not affected and continued operating at full power. The event cut the facility’s electricity output in half.
