SNC-Lavalin has been awarded a contract by BWXT Canada Ltd. for the primary side cleaning of the steam generator tubes at Cernavoda 1, a 706MW Candu 6 reactor, in Romania. The work is due to be carried out in 2016.
BWXT Canada is the original manufacturer of the steam generators at Cernavoda 1 and the lead contractor on this project as part of a 10-year comprehensive agreement for steam generator services with Societatea Nationala Nuclearelectrica, dating back to 2011.
SNC-Lavalin will utilise its Canduclean™ system for the project. This technique 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.
SNC-Lavalin says it has performed sucessful cleaning campaigns for seven reactors over the past decade.
