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.

Energy spectra of delayed neutrons from the mass-separated fission products 79(Zn, Ga), 80, 81Ga, 94, 95Rb, and 129, 130 In have been measured. The neutron envelopes are deduced and compared to predicted envelopes using various mass formulas. The agreement is good for all precursors except for 79(Zn, Ga), whose predicted neutron window is too narrow to reproduce the experimental results.
