Objectives

Most tokamak fusion devices that have been conceived throughout the world do not use Tritium for the fusion reaction. The ITER device (like JET) will operate D+T fusion, which will bring a new aspect to take into consideration for the conception of the whole machine:nuclear requirements through Tritium management and neutron and radiation shielding. The proposed training scheme is addressed to teach young engineers in order to give them the knowledge and the competence necessary to implement nuclear safety in projects for ITER. The aim of the training is to integrate the trainee in a project team for ITER Diagnostic port plug. He will be introduced to fusion and ITER, and will follow specific nuclear engineering courses and training sessions. The trainee will then take an active participation into the implementation of nuclear safety requirement (design, management, QA,documentation, manufacturing…) for the project.


Candidate and training profile:

This trainee will be a graduate mechanical engineer, preferably with good basic knowledge in the nuclear engineering field, with less than 4 years experience in research or science. The training activities will concentrate on the nuclear aspects of fusion and their impact on engineering activities during the whole project life. Moreover, this trainee will act in this training scheme as an expert on nuclear topics for the ITER Diagnostic port-plug project.


Description of Work

During the first two years of the training program, the trainee will be focused on courses and specialization on the scientific topic of the program (i.e. nuclear safety).The trainee will attend an important number of courses detailed below, and along the first two years.


Introductory courses - 3 months during the first year


Specific courses on generic issues - 3 months all along the project


Additional, missing skills should be added. The program will be flexible enough to adapt to the trainees specific abilities, wishes and the exact starting date of the training program. The trainee will apply these specific nuclear engineering methods in a CEA division specialized on these topics or in partnership with a firm specialized in nuclear engineering (such as AREVA TA).


Involvement in the ITER diagnostic port-plug project - 15 months

During the whole program, the trainee will be integrated in a project team. He will participate more and more actively to the ITER diagnostic port-plug 1 project, in order to apply his specific skills in nuclear engineering in the frame of the project. In particular, he will take part to these specific activities:


The trainee will spend about 30% of his time at the partner’s institutes. In particular, he will spend 3 months at FZK to work on neutronic aspects.


Manufacturing issues - 15 months

The trainee will also take an active part in the implementation of nuclear safety requirements for manufacturing issues in the frame of the ITER equatorial port plug 1 project:


Manufacturing follow-up for ITER prototypes or for Tore Supra components will possible depending on the actions in progress on those projects. The trainee will also spend three months at FZJ to work on manufacturing issues for CXRS diagnostic port plug inside the design team and in collaboration with industrial partners.

The goal of this training program is to allow the trainee to become more and more autonomous. He shall be able to take the lead in several tasks and manage them from the beginning to the end. Frequent discussions within the working group are foreseen to keep on track.

Objectives

The fusion reaction needs high magnetic fields, produces high energy neutron and generate very high temperatures. These severe conditions make first wall components highly constrained and causes its wear. Thus, many parts of this region must be replaced or refurbished during the reactor’s life.

The maintenance of a reactor in exploitation is a critical point, because it directly affects the availability of the machine and its economical productivity. Even if the goal of ITER is not to be an industrial reactor, it is essential to consider its maintainability for at least two major reasons: the first is to have powerful available experimental equipment, and the second is to demonstrate that the maintenance by remote handling is possible for the further steps.

In such a complex assembly, it is quite impossible to consider that all the parts are easily removable. Thus, it is necessary to preliminary identify what elements must replaced or refurbished and how often. Moreover, following the component location in the whole assembly, maintenance schemes must be clearly planned. In the case of a replacement, it is obviously necessary to handle the components, and in quite all cases of refurbishment, the operations are not made in-situ, but in Hot Cells. The logistic of this kind of facility must take into account the planned operations, but also the fact that some components could need to be replaced due to unexpected failure.

For a machine like ITER, the maintenance is a very hard challenge, due to its size and environment conditions. All the operation cannot be made hands-on because the level of radiation of the activated components is too high. This is especially true for the In-Vessel materials. This is the reason why the remote handling is one of the most important issues of the whole project. The maintenance, and especially the “remote maintenance” must be taken as design constraints, like those induced by the mechanical and thermal loads and the behaviour under magnetic field and inside vacuum.


Candidate and training profile:

This trainee will be a graduate mechanical engineer, preferably with good skills in maintenance processes, with less than 4 years experience in research or science. The candidate should gather enough knowledge to become an expert in the ITER Maintenance Plan mainly for the In-vessel elements (comprising all attached features ex-vessel).

As the thermonuclear reactor has to support ITER project scientific mission during a long period, it is necessary from the design phases to know about its lifecycle. All the phases of the components life (first testing, commissioning, first mounting on the VV, maintenance scheme, decommissioning, dismantling …) should be taken into account with a special care for the maintenance strategy that is strongly linked with the radiation levels (safety).

During phase I (duration ~9 months) of the project, the trainee will be involved in the ordinary technical work for development of ITER relevant components, e.g. in the Management Support & Design Integration (MDI) Team of the TBM Consortium located at FZK. During the initial phase, the trainee will be taught in CAD and analysis engineering tools. After the initial phase, the trainee will work out independently complete CAD designs of ITER relevant components. The design will be verified e.g. by mechanical, thermal and thermo-hydraulic or neutronic analysis at the end of phase I of the project. The following milestones can be defined for phase I of the trainee program:

In the frame of this work, manufacturing processes (e.g. welding) will be investigated and verified (e.g. in collaboration with CEA Saclay, details tbd, and industrial companies). Appropriate manufacturers will be selected and benchmark-tests will be performed, e.g., by simple welding manufacturing process mock-ups which will be analysed.

Subsequently a manufacturer will be selected who is in charge of manufacturing of the integral mock-up. The manufacturing process will be supervised by the trainee, e.g. presence of the trainee during important manufacturing steps. At the end of phase II a mock-up of an ITER relevant component will be available. The following milestones can be defined during phase II of the project:


R&D training Phase III: Planning / performance of experiments

Objectives

The significant thermal load requires efficient cooling in the in-vessel components of fusion devices. The plasma facing components, first walls and first mirrors need the most critical cooling system, because these are the most thermal loaded components, in addition the mostly eroded ones by neutron radiation, which effects shorter lifetime and more often maintenance and exchange interventions. Due to the strict vacuum circumstances the proper attachment principle of cooling supply pipes and channels are the welding, which can be done only as a remote handling operation during shutdown of fusion device and furthermore only in the hot cell. As it is high importance to keep the maintenance time acceptable short, complex, cooled, exchangeable modules are necessary to develop. During the different phases of design the satisfactory performance of cooling must be kept and checked by thermomechanical calculations.

The aim of this topic is to integrate the trainee in a project team for ITER Diagnostic port plugs. He/she will be introduced to fusion and ITER, and will follow specific thermomechanical engineering courses and training sessions. The trainee will then take an active participation into development of different diagnostic systems for ITER, accommodated in equatorial and upper port plugs (Bolometry, CXRS, LIDAR, Visible/IR Video, etc.)
