Specialised Civil Engineering& Construction Work

More than 50 years’ experiencein the nuclear industry

The history of NTS (Nuvia Travaux Spéciaux) is closely linked to the historyof the French nuclear industry.NTS was originally the specialist nuclear arm of Freyssinet, and becamepart of Nuvia in 2008.NTS has acquired extensive know-how and experience through more than50 years of work alongside EDF to build reactors in France and around theworld. The 150 staff working for NTS have significant experience in on-site workat nuclear facilities, with thorough knowledge of all technical and safetyrequirements.NTS now works in design, engineering, project management and implementation, to meet a range of new build, maintenance and decommissioning needs for civilian or military nuclear facilities in Franceand abroad.

> New BuildSpecialist contractor in civil engineering and structural works

NTS offers a range of innovative, high-performance products andservices to support our customers' new build projects in the nuclear industry, from preliminary design through to construction.

Design, supply and implementation of processes (in particular Freyssinet products):• Pre-stressing solutions for concrete structures• Pre-stressing bars for anchoring equipment to structures• Handling and securing equipment to structures• Seismic protection systems: bearings, snubbers, dampers• Structural instrumentation and monitoring systems• Heavy lifting and handling• Cutting operations

Specialised operations:• Turnkey design and build of complex structural

elements•Management of interfaces between civil works /

mechanical components• Definition, design and substantiation of

bespoke solutions• Development of new processes, products

and tools

> Maintenance and Plant Life Extension

Partnering with plant owners to maintain and extend thelife of nuclear facilities

In-depth knowledge of construction methods is required for anymodifications, repairs or reinforcement work at in-service nuclearsites. NTS has the necessary experience to manage issues in thisfield from civil works to mechanical systems, offering innovativesolutions that comply with the technical and regulatory requirements applicable to nuclear facilities.

Design, supply and implementation of processes:• Solutions for problems with concrete • Solutions for leak-tightness/sealing issues (coatings, cracks etc.)• Repair and reinforcement of concrete pipes• Seismic retrofitting for all types of structures (Foreva TFC® carbon-fibre

fabric, reinforced concrete, structural steelwork etc.)• Retrofitting of structural and electrochemical repair

products and solutions (Foreva® range)• Cutting operations: sawing, drilling• Repair and reinforcement work to equipment anchorage•Work on interfaces between civil works / mechanical

components•Maintenance and repair of cooling towers

Integrated service packages covering:• Inspections• Diagnostics• Definition, design and substantiation of bespoke solutions• General engineering and project management contracts

covering all aspects related to project deployment (logistics, pipe diversions, modifications etc.)

> DecommissioningGeneral engineering and project management services in decommissioning

In-depth knowledge of facilities and structures and an innovativeapproach enable NTS to manage decommissioning projects with a constant focus on safety and compliance with cost targets anddeadlines. The techniques used by NTS take into account the specific issues around decommissioning including containment,waste and effluent management and radiation protection.

Design, supply and implementation of processes:• Thermal cutting• Diamond wire cutting for concrete structures and equipment•Mechanical decontamination operations (surface cleaning)• Remote-controlled demolition and cutting• Specialised lifting and handling operations• Design and development of specific tools

and equipment• Soil surveys and remediation

Integrated projects: • Dismantling equipment and structures•Managing complex operations• Project management• Planning•Waste management

(EDF Creys Malville)• Decommissioning of uranium workshop (AREVA SICN)• Excavation of contaminated soil (CEA Fontenay-aux-Roses)

> EngineeringTeams of specialist mechanical and civil engineers

NTS has an internal Design and Methodology department for civiland mechanical engineering projects. This department can work onpreliminary and detailed design, incorporating technical feasibilityissues and feedback from other projects.

Inspections, analysis and diagnostics:• Structural inspections• Database design and management• Instrumentation • Consultancy and support on structural defects (corrosion, leak-tightness etc.)• Sampling and analysis work

Structural engineering and methods:• Static and dynamic design, calculation and substantiation of structures• Engineering and design for technical solutions (feasibility studies,

preliminary, detailed and construction design) • Expert consultancy•Methodology studies• Design, development and qualification of processes, products and tools• Secondment of on-site engineering teams
