Introduction

Would you like to be involved in the decommissioning and dismantling of radioactive elements located in the former CNGS Target Area? Then, bring your expertise and good practices in the planning and implementation of decommissioning activities. CERN, take part!

You will join the Accelerator Systems Department (SY), which is responsible for the beam-related technical systems of the CERN accelerators. The SY teams design, build and operate equipment systems in all CERN accelerators, and are engaged in ambitious forward-looking R&D programmes.

The position opens in the Sources Targets Interactions (STI) Group, which is responsible for the design, construction, operation and maintenance of all intercepting devices across the CERN complex, including studies related to crystal-based beam manipulations.

In particular, the Targets, Collimators and Dumps (TCD) Section is responsible for the mechanical and operational aspects of CERN's beam intercepting devices, including the spallation neutron target of the n_TOF facility, the antiproton production target, the primary targets for the North and East Halls, all beam collimators, dumps and absorbers of the injector complex and the LHC. The Section has also expertise in dismantling and post irradiation examination of radioactive components.

Functions

As a Nuclear Dismantling Engineer, you will:

• Coordinate the entire dismantling process of the radioactive components in the CERN Neutrino to Gran Sasso (CNGS) target area, including the pion production target, the respective focusing elements, the helium vessels as well as the concrete and iron shielding components;
• Plan and execute scenarios for dismantling, define the intervention modes, the technologies to be employed, the risks and the safety measures required, focusing on pragmatic approaches;
• Understand the mechanical and operational aspects associated to the design and construction of lifting and handling equipment;
• Carry out the technical supervision of mechanical electromechanical equipment, including planning and coordination of tasks and ensuring worksite organisation;
• In collaboration with the project leader, support the execution of the activity, by ensuring distribution of the project schedule and its implementation by coordinating the work of different contractors and multi-disciplinary teams across CERN;
• Draft technical documentation in line with the project requirements and contribute to the documentation to be provided to the Tripartite Authorities;
• Be responsible for specification and follow-up of technical aspects of a contract, including search and selection of suppliers as well as drafting of commercial documents;
• Ensure that environmental, quality and health and safety policies are applied on the work sites, including in terms of radiation safety as well as radioactive waste management;
• Support the upgrade and consolidation activities associated to the HL-LHC dump upgrade and North Area consolidation and physics improvement projects (TCC2 and TCC8 target areas) specifically related to dismantling, clean-up and upgrade works.

Master's degree or equivalent relevant experience in the field of nuclear or chemical engineering or a related field.

Experience:

Required experience in:

• Project coordination and execution of dismantling or decontamination of nuclear or particle accelerator installations, with experience in working in radioactive environment with risk of contamination;
• Preparation of Work and Dose Planning and return of experience in the execution of activities with risk of external and internal exposure to radiation;
• Decontamination techniques, applied to concrete and metallic surfaces;
• Design and licensing of nuclear or particle accelerator installations;
• Preparation of documentation to be shared with nuclear authorities.

Desired experience:

Initial experience in supervising a small team and coordinating multidisciplinary projects.

Technical competencies:

• Knowledge of regulatory framework and best practice in radiation protection;
• Decommissioning and disposal of accelerator components and systems;
• Organisation, planning and control: including supervision of work;
• Knowledge and application of manufacturing methods and work preparation;
• Specification and follow-up of technical aspects of a contract.

Behavioural competencies:

• Demonstrating accountability: working conscientiously and reliably; delivering on promises.
• Solving problems: identifying, defining and assessing problems, taking action to address them.
• Working in teams: building and maintaining constructive and effective work relationships.
• Communicating effectively: ensuring that information, procedures and decisions are appropriately documented; delivering presentations in a structured and clear way; adjusting style and content to the audience; responding calmly and confidently to questions.
• Learning and sharing knowledge: thinking "out of the box" and proposing fresh ideas, insights and methodologies; learning from own successes and failures; sharing knowledge and expertise freely and willingly with others; coaching others to ensure knowledge transfer.

Language skills:

• Spoken and written English: the ability to draw-up technical specifications and/or scientific reports, and/or to make oral presentations.
• Basic knowledge of French language or an undertaking to acquire it rapidly.
