ITER and MAST-U Scenario Developer/Modeller

Job type:

Culham, Oxfordshire

£29,893 to £33,969 pa dependent on experience plus industry leading benefits including an outstanding pension scheme

Closing date:
8th June 2018


Do you want to help shape the future of the world`s energy? Nuclear fusion, the process that powers The Sun, can play a big part in our carbon-free energy future. The Culham Centre for Fusion Energy (CCFE) is part of the UK Atomic Energy Authority and is one of the world`s leading fusion research laboratories. Our scientists and engineers are working with partners around the globe to develop fusion as a new source of clean energy for tomorrow`s power stations.

The Mega Amp Spherical Tokamak (MAST) facility at CCFE is currently undergoing a major upgrade that will enhance the UK`s role in international fusion research. The first experiments with the new MAST-Upgrade will commence in late 2017 and it will be the first tokamak to trial the innovative Super-X divertor - a high-power exhaust system that reduces power loads from particles leaving the plasma. If successful, Super-X could be used in DEMO and other future fusion devices.

This post is a fixed term appointment for a researcher within the Integrated Modelling Group in the Plasma Theory and Modelling department. The postholder will develop and exploit state-of-the-art integrated modelling tools to develop scenarios and study plasma transport in ITER and spherical tokamaks. The postholder will be responsible for integrated modelling activities for MAST-U, and for exploiting (in collaborations) the most advanced transport models developed for MAST-U to make extrapolations to smaller cheaper fusion devices.

JINTRAC is a highly complex, integrated code package developed at JET with the ability to simulate the whole plasma from the very core out to the wall, including plasma-wall interactions. CCFE has successfully used JINTRAC to model JET and ITER plasmas and the postholder, an enthusiastic and meticulous modeller, will work on an upcoming ITER contract to develop integrated scenarios with the aim of achieving the ultimate goal of ITER, the production of 500MW fusion power.

The main responsibilities of the role will include:
-Exploit transport codes to carry out integrated modelling for ITER and MAST-U to:

Develop ITER and MAST-U scenarios.

Do predictive and interpretive core transport simulations for MAST-U plasmas using codes like JETTO with the best available transport models (e.g. TGLF, NEO, and other advanced models).

Perform core-edge coupled simulations with JINTRAC and analyse the results, mainly for ITER plasmas and potentially occasionally also for compact fusion devices.

Exploit codes to understand experimental results relating to transport and confinement: e.g. explaining the observed confinement scalings, and the impact of on-axis and off-axis beams.

Collaborate with and provide transport simulations for other scientists working on MAST-U.

Collaborate pro-actively with universities and other international collaborators in efforts to:

-compare gyrokinetic simulations and advanced transport models with MAST-U data.

-exploit suitable models to make transport predictions for compact fusion devices.

-Responsible for core transport codes (including JINTRAC) on MAST-U, and working with code developers to implement advanced transport models.

-Responsible for maintaining the interface between MAST-U data and the transport code JINTRAC.

-Propose and lead/contribute to research on MAST-U.

-Propose and lead/contribute to research carried out through EUROfusion work packages.

-Report results at science and other regular progress meetings

-Disseminate results through conferences and peer reviewed journal papers.

The work is expected to be divided approximately equally between ITER modelling, and modelling for MAST-U and for smaller, cheaper reactor designs.

Knowledge skills and experience

-PhD level knowledge of plasma physics

-Experience (>3 years) and detailed knowledge of tokamak transport physics and modelling of core and preferable of edge plasma, including particle and heat sources.

-Experience of using simulations for tokamak plasma scenario development

-Experience in running integrated simulation codes within different frameworks and on different platforms.

-Proven ability to conduct independent research.

-Ability to interact with physicists and understand their requirements.

-Good oral and written communications skills.

-The post-holder must be an excellent team-player with an outward facing work-ethos as he/she will work closely with scientists from around the world.

-Experience of using/developing advanced plasma transport models and/or gyrokinetic/gyrofluid codes

-Understanding of scrape-off layer and divertor physics issues.

-Experience in development, installation and exploitation of codes on a wide variety of platforms

-Excellent demonstrated programming skills in Fortran, including with legacy Fortran codes

-Specific developer/user experience with core tokamak plasma transport codes: e.g. JINTRAC.

-Strong record of publications in a closely related field.

-As part of the selection process you may be expected to complete work based simulation exercises and a personality profile either online or onsite.

-Please be advised that this vacancy may close earlier than stated if large or sufficient numbers of applications are received.
-Please note UKAEA do not pay travel expenses for interviews.
-The UK Atomic Energy Authority actively promotes equality and values diversity in our workforce. We operate a number of flexible working arrangements (such as part-time working/job share/home working). Flexible working may be available with this role.
