60 Years of U: Perspectives on resources, demand, and the evolving role of nuclear energy
Recent years have seen growing global interest in nuclear energy and rising confidence in the sector. For the first time since the early 2000s, there is renewed optimism about the industry’s future. This change is driven by several major factors: geopolitical developments that highlight the need for secure energy supplies, a stronger focus on resilient energy systems, national commitments to decarbonization, and rising demand for clean and reliable electricity.

This paper presents a W mockup with an interlayer of diamond/Cu (DC) composite material. As a joining interlayer, DC composite material has high thermal conductivity and accommodative coefficient of thermal expansion. By adjusting the thickness of the DC layer and comparing different forms of armor, the optimal design is the brush armor mockup with a 1-mm-thickness DC layer. The thermal-structural behavior of this mockup was analyzed under the steady-state and transient heat flux by using ANSYS Workbench. The calculated temperature and stress indicate that the mockup can tolerate 10 MW/m2 steady-state heat flux at most. Then a transient heat flux (300 MW/m2 for 5 ms) is loaded on the top surface upon steady-state heat flux of 8 MW/m2. The surface temperature instantly rises to 2300°C, but a cracking trend is not shown at the loaded surface.
