Robotic Steam Generator Maintenance

CECIL® (Consolidated Edison Combined Inspection and Lancing) is a robotic steam generator maintenance system that provides secondary side maintenance.

CECIL Inspection

The CECIL robot is remotely operated and can perform secondary side visual inspections, soft and hard sludge removal, sludge sampling, and both in-bundle and annulus foreign object search and retrieval (FOSAR). The key to CECIL’s success is its ability to access the entire in-bundle area of the tubesheet. In addition, CECIL reduces maintenance costs and increases efficiencies and personal safety.

CECIL systems are currently in service throughout the United States, Japan and France.
