Oxford Sigma Technologies
The fusion industry has been gaining momentum and this decade should yield milestone results to demonstrate fusion energy as a real source of energy. However, fusion energy environmental conditions for the structural and functional materials are extreme and still unsolved.
Oxford Sigma develops enabling materials technologies for fusion energy in order to accelerate the deployment of this carbon-free energy source. The technologies can be found below.
Liquid metal Compatible Materials
For fusion energy to become a commercially successful energy source, key components needs to be demonstrated. Liquid metal breeder blanket technology is one of the key enabling technologies.
Oxford Sigma is on a path to commercialise liquid lithium corrosion resistant technology for breeder blankets for fusion energy. To discover how this technology will be beneficial to you and your organisation, please read the following press releases and contact us.
Protection from Dissolution
The materials that Oxford Sigma are developing aim to protect against dissolution from the corrosive liquid metal flowing environment that is experienced in novel fusion designs.
Resistance to Radiation Damage
Our material microstructure is tailored to provide superior radiation resistance against neutron damage. The neutrons emitted by the fusion reaction can cause significant structural damage to common nuclear materials.
High Temperature Operation
Our company develops liquid metal resistant materials for high temperature operations in breeder blankets. This is to maximise thermodynamic efficiency in electrical power production.
Plasma-Facing Components are exposed to the most extreme conditions known to humankind, these include intense radiation damage, temperatures greater than ~1000 °C, and fusion plasma erosion.
Oxford Sigma has patent pending technology in tungsten-based materials for plasma-facing components in fusion reactors. To discover how this technology will be beneficial to you and your organisation, please contact us.
Increases reactor availabilityOur plasma-facing component technology aims to enable greater reactor availability by extending the operational lifetime of the components compared to the standard fusion monoblock design.
Reduces radioactive waste
Our technology works to reduce the radiological half-life and radiotoxicity burden compared to standard materials during and after commercial operation.
Our technology enhances safety margins due to the innovative solutions in the materials science and alloy design.
Lead-Lithium Fusion Breeder Blankets
The economic success and sustainability of fusion energy is dependent on the tritium breeder blanket devices generating fuel to the levels required to maintain the fusion reaction.
Oxford Sigma has patent pending technologies in lead-lithium breeder blankets materials and designs. To discover how these technologies will be beneficial to you and your organisation, please contact us.
Protection from corrosion
Our corrosion-resistant material design aims to provide genuine solutions to liquid-metal breeder materials challenges. Liquid lead-lithium coolant is another candidate for use as tritium breeders and heat extractors but are highly corrosive, which can be life-limiting to the component.
Resistance to Radiation DamageOur technology’s material microstructure is tailored to provide superior radiation resistance against neutron damage. The neutrons emitted by the fusion reaction can cause significant structural damage to common nuclear materials.
Our company’s expertise in nuclear regulation and compliance enables us to develop, design, and plan the regulatory scrutiny that our technology will need to overcome.
Oxford Sigma has developed a multiphysics dynamic optimiser software to provide an easy-to-use and powerful tool for simulating nuclear fission kinetics, fusion reactors, and radioactive inventories. Details about the software platform can be found below. For interest in using this tool for your projects, please email us.
NeutronicBEAST is a software platform that interfaces with industry standard neutronic and inventory code bases. The capabilities include CAD inputs, workflow optimisation, and Monte Carlo based simulations.
The multiphysics dynamic optimiser tool has been designed from the ground up to enable fast prototyping of nuclear technologies, such as breeder blanket designs, plasma-facing components, and shielding for fusion and fission reactor cores.
Our software platform has an extensive nuclear materials database, which includes standard fission materials, fusion materials, and novel materials. For example, the database includes many of the novel materials such as advanced steels, vanadium alloys, metal hydrides, and high temperature superconductors.
Oxford Sigma is actively engaged in research collaboration with universities and national laboratories around the world to accelerate advanced fission and commercial fusion energy. Some of the ongoing collaborations are described below.
Design Of Radiation-Tough High Entropy Alloys
Oxford Sigma and the Singapore University of Technology and Design are working together on a research program with the objective to rapidly design radiation-tough high entropy alloys with an emphasis on materials suited for nuclear fusion energy systems, such as tungsten alloys.
