Committed to Equal Opportunities


It is widely perceived that to meet the low carbon emissions set by the Paris Agreement; nuclear energy must play a vital role in the decarbonisation of various sectors. The advantages of nuclear power are clear – it is not periodic as solar and wind, the Levelized Cost of Electricity is competitive, the material throughput is negligible per unit of energy generated, and it has a low ecological footprint notwithstanding radioactive waste generated.

However, nuclear energy is not without problems in particular the possibility of material getting outside of government control enabling atomic weapon proliferation. It should be noted that the discharged fuel from a Light Water Reactor (LWR), the primary deployed nuclear power technology today, does not reach the needed purity to constitute weapons-grade plutonium. Plutonium grade is dictated by the ratio of 240 Pu to the total amount of plutonium, which must be less than 7% to be classified as weapons-grade. For comparison, the discharged fuel from a typical LWR has 240 Pu content of more than 19%. However, it is still possible to achieve the necessary plutonium purity by changing the operational procedures of a plant.

However, is it really possible to “kill two birds with one stone”? Can we ensure reactor operation cannot be altered to produce nuclear weapons while enabling nuclear energy for all?

The Project

The objective of this research is to identify a way to ensure that the vendors are able to supply a broader range of customers with fuel that will be more resistant to proliferation. 

A non-proliferating nuclear fuel for various thermal reactor technologies can be obtained by increasing the relative amount of 238 Pu in the generated plutonium. Generally, all the Pu generated in the fuel is a result of the absorption of neutrons in 238 U. This produces 239 Pu, although a fissile isotope, is the gateway to the following Pu isotopes (240, 241, 242) through additional absorption reactions. Studies showed that plutonium with high 238Pu in the mix (above 6%) could be considered proliferation resistant. To ensure 238 Pu to Pu ratio will be above 6% through the entire irradiation cycle, it is proposed to dope the fresh fuel with 241 Am or 237 Np; both are sources for 238 Pu. 

Based on previous preliminary studies, there is clear potential in the proposed method. However, clear conclusions cannot be derived, as initial studies did not consider realistic reactor operation. Nevertheless, even at this point, it is possible to say that no safety issues related to reactor operation are expected. On the contrary, using a strong absorber such as 241 Am will help in mitigating the excess of reactivity at the beginning of the irradiation cycle. 

Thus, the project will explore the impact of fuel modification on the performance of all the currently available thermal reactor technologies – Pressurised and Boiling Water Reactors (PWR and BWR), Hight Temperature Gas-Cooled Reactors (HTGR), Fluoride Salt-Cooled High-Temperature Reactors and Canada Deuterium Uranium (CANDU) reactors.

Purpose of the Job

This role will support the Nuclear Futures Institute and help in achieving its aim to establish “A world leading capability in Nuclear Engineering, which establishes North Wales as a global centre, delivering international partnerships and opportunity from a rich mix of existing and new talent.
