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.

Possibilities for improving the performance of conventional 60 cm thick uniform composition Fe-H2O shields backed by a B4C layer are investigated. The maximum heating rate in the superconducting coils due to (1) Optimally distributing the Fe and H2O across the shield; (2) Optimally distributing the Fe, H2O and B4C; (3) Using TiH2 as the primary hydrogeneous material; (4) Using tungsten instead of iron; and (5) Using a tungsten-copper composite material instead of tungsten, is found to be, respectively, 1.6, 3.6, 6, 32 and 56 times lower than in the reference shield. The development and use of tungsten-, and TiH2-based composite materials for improving the performance and/or economical attractiveness of radiation shields is proposed.
