January 18, 2016 | By Rehana Begg

Montreal – SNC-Lavalin announced that it has been awarded a contract by BWXT Canada Ltd. (BWXT Canada) for the primary side cleaning of the steam generator tubes at Cernavodă Unit 1, for the Societatea Nationala Nuclearelectrica S.A. (SNN) in Romania.

BWXT Canada is the original manufacturer of the steam generators at Cernavodă Unit 1 and the lead contractor on this project as part of a 10-year comprehensive agreement for steam generator services with SNN, dating back to 2011.

SNC-Lavalin has held a strong position within the nuclear industry in steam generator cleaning.  Its CANDUclean system uses a special blasting material to loosen and remove deposits that have built up inside steam generators, while ensuring that adjoining areas are not contaminated.  Primary side cleaning can be performed in parallel on multiple generators, cleaning up to four tubes simultaneously. CANDUclean equipment is modular, and can be adapted to any plant layout.

“Our expertise in servicing CANDU nuclear power plant equipment is second to none,” said Preston Swafford, Chief Nuclear Officer & Executive Vice-President, Nuclear, SNC-Lavalin. “With our experience in the upkeep and proper maintenance of nuclear power plants and equipment, we can help utilities continue to have high capacity factors, and provide clean and reliable energy to Romania. This is just the most recent in our successful steam generator Cleaning business, having performed similar successful cleaning campaigns for seven reactors in the past 10 years.”


As one of Europe’s top operating reactors, the CANDU 6 reactor at Cernavodă Unit 1 has been servicing Romania since 1996. The steam generator tube cleaning work will be executed in 2016.
