Bruce Power: Bruce A Steam Generator (SG) Replacement
Aimed at restarting and extending the life of the laid up Bruce A NGS, Units 1 and 2, Bruce A Limited Partnership (BALP) initiated this project in 2004. BALP engaged SNC-Lavalin to perform this first of a kind replacement of SGs in a CANDU reactor. A total of 16 SGs, each weighing 100 tonnes, were removed and replaced. Part of the operation involved lifting and relocating four steam drums, each weighing 250 tonnes, to make way for the removal of the SGs. SNC Lavalin's services included engineering design, removal of existing SGs, installation and removal of temporary structures, metrology, project management, and installation of new SGs. SNC-Lavalin Nuclear was the winner of the 2010 Canadian Consulting Engineering Award in the category of Natural Resources Industry & Energy for the recently completed CANDU Steam Generator Replacement at Bruce A Units 1&2.

Bruce Power: Bruce B Used Fuel Dry Storage Facility In-Station Modifications
This project involved the design, construction, fabrication, procurement, installation and commissioning of the structures and equipment required to transfer fuel from in-pool storage to dry storage containers. SNC-Lavalin Nuclear's scope of work included conducting seismic analyses, designing, reinforcements and modifications to the ancillary services building, safety analyses (criticality, radiation shielding, etc.), preparing licensing documentation for submission to regulators, and developing an environmental, H&S program for the project. A new 100-tonne crane was also installed to permit processing of fuel. The project was placed in service in 2003, on schedule, and has performed reliably to specifications.

Bruce Power: Bruce A Units 1 & 2 Balance of Plant Refurbishment
In 2006, SNC-Lavalin Nuclear started the Balance of Plant (BOP) refurbishment of Units 1 & 2 at the Bruce Power Plant. SNC-Lavalin Nuclear prepared a project execution plan, ALARA plan, project-specific quality assurance program and site safety plan. SNC-Lavalin Nuclear undertook engineering, design, procurement, supply of craft labour, project management, construction and project closeout services on work packages that included design, fabrication, procurement, testing (including NDE), and installation of certain new or refurbished major equipment, systems and components. Also, SNC-Lavalin Nuclear performed project management services including planning, scheduling and cost control, contract administration, resident engineering, site construction work management and commissioning support.

Hydro Québec: Gentilly - 2 Nuclear Generating Station Refurbishment
Hydro Québec decided to refurbish the Gentilly nuclear station, which was commissioned in 1983 and has been in operation for 26 years. The refurbishment project is aimed at extending the station's operating life to until about 2040. The refurbishment project involves conventional as well as nuclear systems engineering, procurement and construction work. Hydro Québec engaged SNC-Lavalin to provide the following services initially: chemical decontamination of primary heat transport system, turbine generator controls system integration from a Mark II to a Mark VIe, EQ cable replacement, spent fuel bay heat exchange replacement and control panel upgrade, condenser refurbishment and MSR (moisture separator-reheater) replacement.

Nuclear Waste Management Organization (NWMO): Conceptual Design and Cost Estimate Update - Adaptive Phased Management
In 2002-2003, SNC-Lavalin Nuclear, in a joint venture with another company, developed conceptual designs and cost estimates for a Deep Geological Repository (DGR) and a central underground storage facility. In 2009, NWMO engaged SNC-Lavalin to update the DGR and transportation system conceptual design, implementation schedule and cost estimates based on NWMO's Adaptive Phased Management approach. This project included a DGR and associated facilities (e.g. used fuel packaging plant, surface decommissioning facility etc.), a shallow underground facility for temporary storage of used fuel before final placement in the DGR, continuous monitoring of the repository, and a fuel retrieval system.

Ontario Power Generation (OPG): Environmental Qualification (HVAC System Components)
To achieve closure of its commitment to the Canadian Nuclear Safety Commission for fully complying with Environmental Qualification (EQ) requirements under its operating license for the Darlington NGS, OPG embarked on a project to environmentally qualify certain components of the plant's heating and ventilation system associated with the steam protected rooms, such as fuse panels, junction boxes, instrumentation such as control panels/equipment and associated junction boxes for control function, TDF/CDF (what do these acronyms stand for?), and mechanical components such as damper seals, flexible hoses, motors, etc. SNC-Lavalin performed conceptual design activities including identifying various options for addressing EQ requirements, evaluating equipment/component designs, failure modes, and effects, preparing cost estimates and preliminary implementation schedules. SNC-Lavalin Nuclear was also awarded detail engineering design. These activities included preparing draft and final design plans, modification design requirements, technical specifications and drawings, producing design engineering and construction packages for each discipline including human factors engineering reports

Xcel Energy: Prairie Island NGS Unit 2 Steam Generator (SG) Replacement
Prairie Island is a two-unit Westinghouse nuclear plant built in the early 1970s. The contract for the removal of the existing SGs and installation of new SGs was awarded to SNC-Lavalin Nuclear based on its successful experience in replacing 16 SGs at the Bruce Power plant in Ontario, Canada and an advanced laser scanning and computer modelling project successfully carried out by SNC-Lavalin Nuclear in Prairie Island Unit 2. Among the services included under the scope of work, we can mention: overall project management and project quality assurance, ALARA planning, radiation protection and decontamination, detailed metrology and modelling. The management of subcontractor services included: handling of SGs on site, all welding, weld inspections, and post-weld heat treatment, final hydrostatic tests and afferent documentation, preparation of the OSGs for off-site shipment, etc.

Wolsong Nuclear Power Plant
The four-unit Wolsong CANDU6 station is located on the southeast coast of the Republic of Korea. The design of this station began in 1976. The construction was completed in record time, with the station achieving full power in 1982. SNC-Lavalin Nuclear provided site investigation studies, engineering and design services for buildings, facilities and process systems excluding the nuclear steam supply. The calandria tubes were installed in the calandria in a temporary building on site. This innovative measure considerably reduced the construction schedule. SNC-Lavalin Nuclear also provided engineering and design services for the turbine and auxiliary buildings, as well as construction management and project management, and it participated in commissioning and operator training.
