SIXENSE’s design office, with the experience of several hundred projects in the nuclear asset management sector (both civil and military), find solutions for our client’s problems in order to optimise the durability of their infrastructure whilst complying with nuclear safety requirements.

 

Services range from the design of facilities based on comprehensive knowledge of nuclear regulations (ETC-C, RCC CG, RCC CW, Safety Regulator Standards and the specific standards of large clients), via the optimisation of structures using advanced methods validated by the regulatory bodies, technical support on projects for their presentation to authorities, and the study of decommissioning operations.

Our expertise in advanced studies applies to various fields in nuclear asset management

Support for all actors in the sector:

  • Operators
  • Research Institutes
  • Safety Authorities
  • Design Managers
  • Construction Firms

Multiphysics expertise:

  • Linear and non-linear seismic behaviour
  • Seismic safety assessments
  • Consequences of severe incidents (plane crash, internal/external explosions or fire, tornados)
  • Assessment of ageing effects

Involvement at every stage in the life-cycle of facilities and equipment:

  • Design of new facilities, including parametric studies according to safety requirements
  • Design review of facilities for approval by regulators
  • Assessment of existing facilities and infrastructure
  • Definition of technical solutions to extend the lifespan of facilities (reinforcement, use of innovative methods, tests)

Innovation:

  • Development, in partnership with EDF, of a worldwide unique constitutive law, able to take into account multiphysics effects (water, drying, pre-stressing, creep, thermal and cracking effects) on ​​concrete containment structures in order to predict leakage flows through the reactor container – ‘The VERCORS project’.
  • Development of digital twins for infrastructure enabling near real-time monitoring
  • Participation in research projects to design the nuclear structures of the future

Advantages of our advanced studies

 

  • Our design office comprises engineers and scientists from the world of applied research with experience in nuclear asset management. We focus on the use and development of digital tools for modelling the behaviour of materials and structures, qualified for their application to the nuclear field.
  • We have already completed several hundred nuclear projects, with numerous successes in safety demonstrations, in order to extend the lifespan of facilities by minimising reinforcement work.
  • We study methods always at the cutting edge of research and systematically approved by the ASN.
  • The capacity to analyse infrastructure, from civil engineering to equipment.
