Nuclear New Builds

We provide systems and components for nuclear reactor builds and steam supply systems.

Nuclear New Builds

Building on our experience on different types of reactors over the last fifty years, we supply systems, components and services for the NSSS (Nuclear Steam Supply System) as well as BOP (Balance of Plant), for various Nuclear Power Plants including PWR, BWR, CANDU and VVER. Furthermore we are present in the nuclear fusion sector through the realization of the fusion reactor ITER (International Thermonuclear Experimental Reactor) for which it contributes to the supply of fundamental components of the plan.

We are expert in most aspects of nuclear plant design and engineering. Some of our service include:

  • Analysis of radioactive protection requirements
  • Fluid and thermal-hydraulic and Licencing analysis
  • Fluid system design and integration
  • Fire risk assessment and fire fighting systems
  • Design and supply of instrumentation and control systems
  • Plant layout design and integration
  • Design and supply of electrical distribution systems

We are at the forefront of the technological development of new NNPs, providing a significant contribution to Generation III+, cooperating with Westinghouse since the early 1980s in the development of Passive Plant Technology. Whilst we have been a key contributor to the Design Certification of AP600 and AP1000 NPPs, we look at the future. 

We are actively involved in Generation IV international programmes. In this context, we are acting as leader for the Lead-Cooled Fast Reactors development programmes, for the successful completion of the "Advanced Lead-cooled Fast Reactor European Demonstrator" (ALFRED) and participating to the design of systems and components for the SCK-CEN Multi-Purpose Hybrid Research Reactor for High-tech Applications (MYRRHA), in the frame of the FEED (Front End Engineering Design) programme.

Generation II&III

​We have built our strength upon trusted partnerships with major vendors, with our extensive qualified supply chain and with our own customers.

We are proud of our involvement with Generation II, III and III+ nuclear projects worldwide. Here are just some to name a few:

  • Sanmen, a AP1000 reactor in China,
  • Mochovce, for the completion of 2 VVER units in Slovakia, 
  • Cernavoda, a CANDU reactor constructed in Romania.

Our experience on different plants design provides us with the knowledge and capability to offer our clients innovative solutions and components to improve safety and reliability of the existing nuclear power plants. With continuous ongoing innovation and the anticipated breakthrough of Generation IV, we remain focused on providing our expertise to present generation nuclear power plants.

Generation IV&SMR

​We are committed to the future of nuclear energy: we are an active member of NUGENIA (Nuclear Generation II and III Association) and ESNII (European Sustainable Nuclear Industrial Initiative), two pillars of the SNETP (Sustainable Nuclear Energy Technology Platform), which coordinates initiatives on nuclear fission towards the collective vision of Europe's transition to a low-carbon energy mix by 2050. 

In addition to its role in SNETP, Ansaldo Nucleare, through Euratom, chairs the GIF-LFR provisional System Steering Committee. We are focusing our commitment on research studies of innovative Light-Water Reactors (LWR) and Heavy Liquid Meal (HLM) fast reactors, for energy production, as well as for transmutation and irradiation purposes through two streams:

Small Modular Reactors (SMRs)

In a general context of financial uncertainties and accelerated growth of new economies, we are looking at SMR as an attractive solution to a worldwide increasing demand for carbon-free electricity, thanks to the reduced financing barriers, as well as to the increased flexibility and adaptability to local grids and siting conditions.

We have participated to the design of main RCS (Reactor Cooling Systems) components such as special Helicoidal Steam Generators.

Generation IV

​Generation IV reactors are currently designed to improve safety, sustainability, efficiency and cost for nuclear plants. A number of reactor types are being developed. We have been developing LFR technology since the early 2000' and we consider it capable of meeting the highest performances in terms of sustainability, safety, proliferation resistance and economics, i.e. addressing long-term goals set out by the Generation IV International Forum (GIF). By guaranteeing the highest level of safety and potentially excluding any domino effect, the Lead-Cooled Fast Reactor (LFR) technology is an optimum candidate for multi-unit sites, as an essential competitive character of the SMR philosophy.

 

Fusion

Fusion is a carbon-free source of energy based on the same principle that powers our sun and stars. We have spent over 30 years involved in international nuclear fusion research programs, providing both engineering and design services and supply of high-tech components. In particular, we have contributed to:

JET (1990 - 1998), the world's largest operational magnetic confinement plasma physics experiment located in Abingdon, United Kingdom.

FTU (1989 - present), a tokamak for the client ENEA developed in Frascati, Italy.

Ignitor (1986-2009), a tokamak designed to handle substantial burning of deuterium-tritium plasma developed in Frascati, Italy.

ITER, one of the most ambitious energy projects in the world today. A collaboration of leading engineers and scientists will work together to create the world's largest tokamak. This will be the first fusion device to produce net energy.  We are contributing the following to ITER:

    • Design and supply of key components including the ITER vacuum vessel
    • Design of the tokamak cooling water system (TCWS) piping
    • Supply of divertor Inner Vertical Target (IVT) prototypes.
