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.

The electron recoil spectra from gamma rays produced by the interaction of 14-MeV neutrons with 0.5, 1.0, 3.0, and 7.0 mean-free-paths (mfps) of nitrogen have been measured with NE-213 scintillators positioned at 26, 30, and 120 deg at distances ranging between 7 and 10 m. Thin wall spherical Dewars filled with liquid nitrogen, with radii dimensions equivalent to the above number of mfp, were bombarded with a centered nominal 14-MeV neutron source. Calculations of the gamma and recoil electron spectra have been carried out with the ENDF/B-IV and ENDL neutron-gamma libraries. Comparison between the measured and calculated electron recoil spectra shows that the discrepancies are not larger than 10%. This agreement implies that the calculated gamma-ray spectra are expected to give a good description of the gamma transport in nitrogen from a 14-MeV neutron source.
