Process Modeller (Fuel & Power)

Working arrangements

Please note this role does offer hybrid working, our model sets out a minimum 60% onsite / 40% home working split

Part time working or job share options will be reviewed on an individual basis.

Overview

An important aspect of a commercially viable fusion power plant is the integration between the Tokamak and the systems involved in supporting its operation. Two such systems are: the Fuel Cycle, supporting breeding, extracting and fuelling aspects of a power plant and the power generation cycle, realising the net energy output following the system power needs against the production capabilities.

Reporting to the Head of Plant Prediction & Simulation, the Power Generation and Fuel Cycle Modeller will be a member of the wider Science, Engineering and Technology group providing analytical and product development resource to the wider business towards, tokamak design and operation, business and investor insights, and Fusion Pilot Plant systems integration.

Responsibilities:

• Be the central point in the designs of, both:

- A power generation and balance of plant, supporting plant layout

  - A fuel cycle system supporting, start-up tritium inventory, doubling time, residence times and fuel losses and efficiencies

• Develop and implement computational models for fusion fuel cycles, including tritium breeding, fuel production, and recycling processes.

• Integrate different primary loops and assess the options for different secondary loops configurations (steam, carbon dioxide, helium, etc.)

• Assess thermal and parasitic loads in systems such as, breeding blankets, divertors, first walls, limiters and, vacuum vessel.
• Assess the wider Balance of Plant energy use and system requirements (e.g. ultimate heat sinks).
• Conduct literature reviews and gather data on technologies, materials properties, and plant concepts relevant to the Power Generation and Fuel Cycle systems.
• Collaborate with team members to analyse and interpret simulation results, identify trends, and evaluate performance metrics.
• Support the validation and verification of fuel cycle and power generation systems through comparison with experimental data and benchmarking against established codes.
• Contribute to the documentation of modelling methodologies, results, and findings for internal reports and publications.

• BSc or MSc in Chemical Engineering, Physics, Nuclear Science, or a related field.
• Computationally competent in fuel cycle and/or power generation analysis tools, or similar applications
• Proficient in the use of the Aspen suite (Aspen+, Aspen Custom Modeller, Hysys and, Heat Exchanger Tools).
• Experience in producing system design descriptions and system interface documentation
• Experience in analysis and research

Desirable:

• Knowledge of programming languages such as C++, Python, MATLAB, or FORTRAN

• Salary dependent on skills and experience and will be discussed from the outset
• 28 days (inclusive of festive break) holiday plus bank holidays
• Eligible for discretionary performance related bonus

About Us

What if there was a limitless, safe, clean, low-cost energy source, providing much needed global energy security? What if that energy source could also help reduce climate change? We believe that’s fusion energy. Tokamak Energy is a leading global commercial fusion energy company based near Oxford, UK. We have an unrivalled track record designing and operating spherical tokamaks; the optimal route to commercial fusion energy.

In addition to fusion energy, Tokamak Energy is recognised as the leader in High Temperature Superconductor (HTS) magnet, design, numerical modelling, and prototyping. Our dedicated HTS magnet team, in collaboration with key manufacturing partners, is focussed on becoming the leading supplier of HTS magnets to multiple markets.

The company, founded in 2009 as a spin-off from the UK’s Culham Centre for Fusion Energy, currently employs a growing team of over 250 people with experts from the UK and around the world. It combines

world leading scientific, engineering, industrial and commercial capabilities. The company has 70 families of patent applications and has raised $250 million, comprising $200m from private investors and $50m from the UK and US governments. Our US subsidiary, Tokamak Energy Inc, was established in 2019.

Come and be a part of a dynamic and innovative team who are striving to provide a solution to one of humanity’s greatest challenges: clean and sustainable energy for all.
