Reporting to the Technical Department, the calculation expert is involved in complex mechanical equipment design projects for the nuclear industry, and carries out various mechanical and thermo-mechanical (and possibly thermo-hydraulic) studies in collaboration with other teams in the Technical Department.

In this context, your main tasks will be as follows:

You'll be involved in all phases of a project, from the tender phase, studies (feasibility, APS, APD, EXE), realizations (consultations, contracting, realization, assembly), factory tests, on-site commissioning (assembly and testing).

-You will work on the design of a variety of systems and equipment, in collaboration with the project team and other engineering offices in the technical department.

-You analyze the input data for a call for tenders, a project or a business deal, and define and justify calculation hypotheses based on equipment life phases, in line with nuclear standards.

-You will carry out mechanical dimensioning calculations (finite element and analytical) in line with nuclear standards.

-You produce technical documents in your area of expertise, scrupulously respecting the technical perimeter.

-You draw up specifications, consult suppliers and analyze the offers received.

-You take part in the technical verification of deliverables produced in your area of expertise.

-You take part in design reviews to validate the technical solutions adopted or identify/anticipate any technical, cost or scheduling problems, and suggest areas for improvement.

Your assets

Higher technical education (Bac +5) (engineering school or university equivalent) in mechanics, numerical simulation, ideally with a minimum of 8 years experience in mechanical calculations and/or thermo-hydraulics in a Design Office in the nuclear field.

-Proficiency in numerical simulation software such as ANSYS (Mechanical using APDL or Workbench) or SYSTUS is essential. Knowledge of the following software would be an additional asset: PIPESTRESS, ANSYS CFX or FLUENT.

-You have solid experience in nuclear equipment, particularly under pressure. Knowledge of the following codes and standards is a real plus to help you get to grips with the job: RCC-M, Eurocodes, 13480, 13445, FEM, ASME, etc.

This position is subject to administrative investigation.
