The CORTEX project: Improving nuclear fleet operational availability
We often define noise as an unwanted disturbance, especially acoustic in nature. Neutron noise, by contrast, is a direct measure of the dynamics of a nuclear core. It can be used for core monitoring without disturbing plant operation and by using the existing core instrumentation. The European CORTEX project aims to develop an innovative core monitoring technique using neutron noise, while capitalizing on the latest developments in neutronic modeling, signal processing, and artificial intelligence.
Challenge: Accelerate development and qualification of advanced materials.
How: Use science-based design to reduce the development and qualification timeline for new nuclear fuels and advanced materials that can withstand extreme fission, fusion, and space power and propulsion environments.
Background: Advanced fission and fusion reactor designs offer many potential benefits, but will require new materials to be optimized. These advanced reactors have unique challenges that call for materials to resist corrosion when in prolonged contact with liquid salts or liquid metals, remain strong at elevated temperatures in a neutron field, maintain structural integrity when exposed to high fluxes of light ions and high heat flux, resist reaction in a loss of coolant event, and more.
Materials must be developed and qualified for each of these areas so that they can be implemented in new reactors. Materials issues lie at the heart of many of the technology issues that need to be solved. Without advanced materials, adequately qualified so that they can be used in engineering designs, we will never have a viable fusion or advanced fission power plant. This is a multi-faceted challenge that benefits not only nuclear energy research, but has applications for many other industries.
The current development and qualification timeline is long, especially due to limited experimental facilities and capabilities for in-reactor material irradiation testing. Significant scientific advances over the past few decades have enabled us to improve our understanding of irradiation effects on materials, including predictive capabilities. As such, we believe we can utilize these advancements to accelerate the materials qualification timeline, effectively reducing that barrier against deployment of future reactor technologies. Realizing this goal will include smart use of advanced modeling approaches, the establishment of experimental facilities and data generation for validation analysis (especially for advanced reactors), and reconsideration or modification of existing requirements for in-reactor material irradiation testing.
Additionally, decades of ion beam irradiation have proven it to be an extremely useful tool to enhance the understanding of radiation damage in materials for nuclear applications. Inducing radiation damage utilizing ion beams in structural materials and fuels causes high displacement damage rates and therefore accelerates the research on the materials response under these conditions.
