Application deadline: 28/08/2022

Domain: Construction Domain

Department: Plant Construction Department

Division: Mechanical Implementation Division

Section: Tokamak Cooling Water System Section

Group: TCWS Delivery

Job Family: Construction

Job Role: Engineer – 2

Job Grade: P2

Language requirements: Fluent in English (written & spoken)

Contract duration: Up to 5 years

Specific note : This vacancy is for less than 4 years, the employment contract is valid until December 2025, while it will be subject to the contract renewal process according to the staff regulations.


As a Structural Design Engineer, you will be responsible for the design and analysis of the structural supports for the Tokamak Cooling Water System (TCWS) piping and equipment.

You will also contribute to the procurement and the successful construction of the TCWS piping system, in addition to participating in the pre-assembly and pre-testing of the TCWS piping system.


The ITER TCWS has three separate primary heat transport systems supported by three additional systems, with a requirement to remove approximately 1,000 Megawatts of heat. These systems perform safety functions for confinement of radioactive material, confinement of high energy liquid, and decay heat removal which is generally lower in magnitude (less radioactive material, pressure, and decay heat) but of similar function to commercial fission reactors. The systems have 33 km of nuclear-grade piping, which is a comparable size to a commercial fission reactor water system.

Key Duties, Scope, and Level of Accountability

  • Produces static and dynamic stress analysis calculations and reports of the TCWS piping and equipment supports and structures according to ASME Code Section NF and ANSI / AISC using GTSTRUDL, Staad Pro, ANSYS or similar software;
  • Maintains a fluent dialog with 3D designers and support designers to agree on the optimal required support configuration;
  • Produces loads reports in coordination with other sections and clients (Buildings, etc.);
  • Monitors the structural analysis produced by industry or Domestic Agencies (DAs) for the assigned systems;
  • Issues Engineering Work Packages for the TCWS and reviews construction and installation work packages
