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.

An equation is derived to estimate the perturbing effects on the neutron spectrum caused by a spectrometer inserted in an experimental assembly. This equation is applied to estimate the spectrum perturbation by a miniature NE-213 fast neutron spectrometer in a graphite assembly. The results show that the perturbation effect is smaller than the experimental errors and uncertainties, and that the effect caused by the neutron-sensitive volume is smaller than that caused by the surrounding materials.
