About LD-SAFE consortium

CEA (French Alternative Energies and Atomic Energy Commission, is a French State owned organisation and a key player in research, development and innovation in four main areas, including nuclear energy. As a nuclear operator, CEA carries out construction and renovation of its facilities, as well as decommissioning after shut down and legacy waste retrieval: 21 out of 43 of its civilian nuclear installations are under decommissioning, with contamination levels sometimes very high, and a wide diversity of facilities, from laboratory scale to industrial plants.

Facilities under decommissioning at CEA encompasses almost all types of nuclear facilities: almost all types of experimental reactors, some industrial reactors (gas cooled G1-G2-G3 and fast breeder Phénix), accelerators and irradiators, chemistry laboratories, industrial fuel cycle processing units, industrial effluent treatment stations, waste treatment and storage facilities, etc.

Equans “ENERGY TRANSITION & INTEGRATED SOLUTIONS” (INDUSTRY) with its department “Specialized Nuclear Services” (SNS) is a turnkey solutions provider in the nuclear sector, carrying out engineering, on-site execution as well as project management of a variety of projects.
SNS is specialized in the development of industrial solutions in the nuclear field. SNS is former Transnubel and Tecnubel. Transnubel was founded in 1969 by Belgonucleaire (the MOX plant that has since been dismantled) as a transporter of radioactive material. Since then, many customers have joined and activities also include related forms of engineering. Tecnubel was founded in 1985 as a maintenance specialist for nuclear installations. By investing in know-how and new technologies, the group has grown to become a highly integrated solutions and service provider for the nuclear sector in Belgium and abroad specialized in decommissioning and decontamination.
Today, the SNS department comprises three sections: Proximity, Nuclear Contracting and Design, Engineering & (Fuel) Solutions. The mission of the department consists in delivering total solutions to the nuclear sector including onsite technical services and material handling, nuclear logistics, characterization, decontamination and dismantling projects, design & building of nuclear packagings and tooling and various expertise in specific nuclear domains. We easily take care of implementation, engineering and project management thanks to our team of operators and technicians surrounded by highly skilled engineers. This way, flexibility and speed are our key to success in providing a wide range of services. SNS is active in nuclear sites in Belgium and abroad (e.g. France, Germany, Slovenia, The Netherlands, Sweden, Serbia) such as NPP, research centres and waste treatment facilities.
Design, Engineering & (Fuel) Solutions includes feasibility studies and technical specifications, technical calculations (mechanical, thermal, leak tightness, criticality and radioprotection), safety files and the design, construction and delivery of equipment, packaging and installations. Nuclear contracting includes the decommissioning and dismantling projects of nuclear installations and equipment, decontamination activities on materials and installations and waste sorting and characterization projects. Proximity is managing a large group of qualified operators to perform services in nuclear installations.

Vysus Group is a leading engineering and technical consultancy offering specialist asset performance, risk management and project management expertise across complex industrial assets, energy assets (oil and gas, nuclear, renewables), the energy transition, rail and road.

Legacy meets future
LR’s Energy business was founded in the 1930s, following LR’s diversification from marine assets into the oil and gas industry. Growing considerably through numerous strategic acquisitions, we have become one of the leading engineering consultancy partners of choice.

Vysus Group retains its entire capability and continues to offer its full suite of technical, regulatory and operational expertise globally. Driven by its purpose to help clients manage risk and maximise performance, blending deep technical knowledge and data-driven insights with hands on expertise.

Westinghouse has a 130-year history of innovation that began when its founder, George Westinghouse, commercialized the alternating current and forever changed the way electricity was distributed.

Its legacy continues in the nuclear era, which originated when Westinghouse built the world’s first commercial pressurized water reactor in Shippingport, Pennsylvania. More than 60 years later, 430 nuclear reactors operate around the world using Westinghouse technology.

While Westinghouse is proud of its past, its real value lies in providing a guide for our future. As the world strives to address the challenges of a changing climate, Westinghouse is constantly rethinking the way of delivering nuclear energy. From the efficient and economical AP1000^® nuclear plant to the new eVinci™ microreactor for remote energy applications, Westinghouse is leading the way with the development of new nuclear technologies that will enable us to share the benefits of this reliable, clean, safe and economical source of energy for generations to come.

In 2023, Westinghouse acquired 100% of Tecnatom, partner of the LD-SAFE consortium.

The Institute for Radiological Protection and Nuclear Safety (IRSN) is specialized in risk assessment which was created in 2001 from the merger of the IPSN (formerly CEA) and the OPRI. IRSN is reporting to the ministers responsible for environment, research, public health, defense, and industry. IRSN (1680 researchers) contributes to public policies relating to nuclear safety and protection of human health and environment with respect to ionizing radiation. The Airborne Pollutants and Containment Study and Research Department has developed its expertise in aerosol physics, containment, air cleaning, ventilation and multiphase flows characterization in hostile conditions. The Aerosol Physics and Metrology Laboratory (LPMA) has long been involved in developing aerosol science in France in conjunction with various academic and industrial partners. It is located at the CEA site in Saclay (Essonne, France). The LPMA carries out experimental research, studies and technical assessments related to the characterization of aerosol source terms at facilities, in normal and accident situations:

• Basic research and studies, as well as applied studies, on aerosol physics and metrology, and on-air contamination by natural sources, both radioactive and non-radioactive, and anthropogenic sources (formation, physical and chemical changes, and transfer, mainly via containment barriers).
• Particle suspension by air flow or by the fall of potentially dispersible materials (powders, contaminated objects, liquids), suspension during dismantling operations.
  The mission of the Safety and Research Facilities and Reactors in Dismantling Department is to perform the technical tasks related to the actions entrusted to IRSN to help assess safety.
• Facilities dedicated to nuclear research (research, irradiation or experimentation reactors, particle accelerators, nuclear laboratories, etc.), from their creation to their decommissioning.
• Certain industrial installations, such as Saclay’s irradiators and the artificial radioelement production plant, from their creation until their decommissioning.
• Treatment and storage facilities for effluents and waste produced by the CEA and EDF sites, from their creation until their decommissioning.
• Nuclear power reactors shut down permanently until decommissioning.
