Canadian engineering giant SNC-Lavalin said Tuesday it had been awarded four contracts by Korea Hydro & Nuclear Power Co., Ltd, to conduct assessments and computer code upgrades at the Wolsong site in Korea.
The contracts, valued at $22 million, were awarded to Candu Energy Inc., an SCN-Lavalin subsidiary.
“The awards consist of multi-campaign field inspections, prolonged operation assessment and thermalhydraulic computer code updates,” the company said.
The inspections will provide assurance to KHNP and the Korean nuclear regulator that the CANDU nuclear reactors at the Wolsong site continue to be safe to operate until the next planned inspection. All the contracts are within SNCL Engineering Services, the cornerstone of our strategy moving forward to greater growth and support for our partner and customer.
SNC-Lavalin will inspect fuel channels and perform pressure tube sampling campaigns for Wolsong Units 2, 3 and 4, all to begin in 2020. An engineering analysis and assessment will be completed on the fuel channels and fuel channel components (including calandria tubes) for Wolsong Units 2, 3, and 4.
The thermalhydraulic computer codes (CATHENA and NUCIRC) update will support KHNP in updating the safety analysis report for Wolsong units 2,3 and 4.
“SNC-Lavalin has performed these campaigns for over 20 years and continues to conduct these inspections on both international and domestic CANDU reactors using the latest tools and technologies for inspections and non-destructive testing,” said Sandy Taylor, President, Nuclear, SNC-Lavalin.
The Wolsong CANDU nuclear power plants are owned and operated by KHNP. The four units at Wolsong are 700 MWe class CANDU 6 reactors. Units 2, 3 and 4 began operation in 1997, 1998 and 1999 respectively.
