Example Completed Projects:
Fusion Materials Selection for Tokamak Reactors
Oxford Sigma delivered fusion materials strategy, development, and design for a private fusion company’s tokamak reactor design. This project focused on materials development to withstand 14.1 MeV neutrons and plasma exposure, covering the structural, functional, shielding, and breeding materials of the reactor.
Fusion Central Column Tritium Breeding
Oxford Sigma simulated novel in-board tritium breeding and superior radiation shielding designs to minimise the neutron and gamma fluxes at the central solenoid of a tokamak reactor. The company deployed NeutronicBEAST to rapidly prototype tens of thousands of designs to find the optimal solution(s).
Molten Salt Reactor Core Engineering
Oxford Sigma supported a private company’s molten salt reactor core design by analysing fuel facing materials, reactor vessels, and in-core support structures. This work covered analysis of the applicability of nuclear codes and standards, along with understanding the effects of molten salt corrosion and radiation damage of core materials.
Assessment of Fusion Energy for Investment
Oxford Sigma has provided guidance on technological, supply chain, and commercial challenges of fusion energy to investment and energy firms. The outcome de-risked and identified opportunities where strategic investment could provide maximum effectiveness in the industry.
