Steam Generator Maintenance



CECIL (Consolidated Edison Combined Inspection and Lancing) is a robotic steam generator maintenance system developed for secondary side maintenance. By accessing the entire in-bundle area of the tubesheet, CECIL can provide superior cleaning capabilities, reduces maintenance costs and extends the life for pressurized water reactor (PWR) steam generators.

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