Overview

Are you looking for an exciting opportunity at the heart of an ambitious fusion energy project? Join our Fusion Technology and I&C Division (FTIC) within the Engineering Service Department (ESD) as a Mechanical Engineer, Divertor.

As a Mechanical Engineer, Divertor, your goals will include:

• Performing the entire engineering life cycle (specification, design, qualification, procurement, installation, integration, commissioning and maintenance) for the scope of activity.

• Providing engineering input and technical support for the scope of activity.

• Ensuring deliverables are produced according to project schedule and budget, within a quality-assured environment that requires rigor and a systematic way of working.

• Developing, under the leadership of your discipline manager, your skills and experience for the benefit of the Project.

The ESD provides the required skilled engineering resources or services, which are necessary for the successful completion of the ITER Project.

FTIC Division provides technical support to the ITER project in the field of design, analysis, and lifecycle management of critical fusion and I&C systems.

Being a member of the FTIC Division, you will have the opportunity to share and develop your expertise with other colleagues working in the same discipline on different ITER units.

Find out more about the Divertor here:

The initial scope of activity will be focused onthe Divertor which is located at the bottom of the Vacuum Vessel and is actively cooled by pressurized water. The main function of the Divertor is to minimize the impurity content in the plasma by intercepting the magnetic field lines, thus neutralizing the plasma, which is then pumped away by the vacuum pumping system. The Divertor is attached to the Vacuum Vessel by means of customized cover plates. The candidate will support the finalization of the Rails' design, manufacture and procurement through installation.

Key Duties & Responsibilities

Primary Responsibilities:

• Contributes to the delivery of the procurement arrangement for the divertor scope of activity.
• Conducts stress analysis of Divertor components using Finite Element Method, assesses strength per structural codes, and prepares technical reports.
• Writes technical documentation as required for the procurement, fabrication, qualification and testing of the equipment, prepare relevant tenders, and updates documents as needed.
• Follows up on the manufacturing for the scope of activity including qualification tests and final acceptance tests (FATs).
• Collects and verifies input data for the design of the assigned scope and reviews the deliverables produced by external design contractors.

Additional Responsibilities:

• Provides assistance to the Domestical Agencies, contractors and ITER groups to carry-out engineering, R&D, interface control and procurement work as required.
• Reviews detailed workshop drawings or any Installation Procedures, Inspection & Test Plans and the installation testing issued by the installation Contractor.
• Issues inspection and observation reports when and where required.
• Provides expert criteria for structural and mechanical discipline related problems and follows-up on the resolution of the field engineering changes and installation non-conformances.

Please note that job descriptions cannot be exhaustive, and the staff member may be required to undertake other duties, which are broadly in line with the above primary responsibilities.
