Application deadline: 21/08/2022

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: P3

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 Mechanical Engineer, you will be responsible for the overall design and analysis of the pipes and supports for the Tokamak Cooling Water System (TCWS). You will also manage the procurement of select TCWS components and participate 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

  • Performs pipe stress analysis and support design of the TCWS;
  • Responsible for the production and issuing of several TCWS Engineering Work Packages;
  • Provides in-field engineering support to construction during prefabrication and installation of the TCWS;
  • Manages procurement and installation of some TCWS components (such as tanks, filters, etc.);
  • Acts as contract manager for some TCWS components (such as tanks, filters, etc.) manufacturing, ensuring compliance of the equipment with the design and quality expectations;
  • Supports procurement and installation of piping, supports, and valves for the TCWS;
  • Supports the installation and testing of TCWS piping and equipment;
  • Ensures that the TCWS piping and equipment design is properly integrated on the ITER site and with the interfacing systems;
  • Reviews documents, configuration models and drawings (including P&IDs);
  • Ensures that TCWS piping and equipment is compliant with the ESP-ESPN (Nuclear Pressurized Equipment (from French “Equipements Sous Pression Nucléaire”) French rules;
  • Analyzes and checks the stress analyses of the TCWS piping systems and update the TCWS load specification accordingly;
  • Ensures that the TCWS piping and equipment design is properly integrated, installed and finally tested on the ITER site and with the interfacing clients/systems;
  • May be requested to be part of any of the project/construction teams and to perform other duties in support of the project;
  • May be required to work outside ITER Organization reference working hours, including nights, week-ends and public holidays.

Measure of Effectiveness

  • Issues high quality documentation, such as TCWS piping and support stress reports on time;
  • Ensures that TCWS components are delivered as per the schedule and within budget;
  • Manages contracts effectively and proactively anticipates issues by providing suitable solutions;
  • Produces and reviews EWPs on time to minimize any disruption to the schedule;
  • Contributes to ensuring satisfaction of safety and functional requirements flow-down;
  • Propose solutions to specific requests or process improvement.
