Why should safeguards by design be a global effort?
Jeremy Whitlock
I can’t think of a more exciting time to be working in nuclear, with the diversity of advanced reactor development and increasing global support for nuclear in sustainable energy planning. But we can’t lose sight of the need to plan for efficient international safeguards at the same time.
Global nuclear deployment has been underpinned since 1970 by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), making it a key customer requirement for governments to demonstrate unequivocally that the technology is not being misused for weapons development.
The International Atomic Energy Agency (IAEA) has helped verify this commitment for more than 50 years, but it has never safeguarded many of the advanced reactors (and related fuel cycle processes) being developed today.

In this study, activation cross sections were measured for the 71Ga(n,)72m+gGa reaction at three different neutron energies from 13.5 to 14.8 MeV. The fast neutrons were produced via the 3H(d,n)4He reaction on the Pd-300 Neutron Generator. Natural high-purity Ga2O3 powder was used as target material. Induced gamma activities were measured by a high-resolution gamma-ray spectrometer with a high-purity germanium detector. The data for the 71Ga(n,)72m+gGa reaction cross sections are reported to be 1.93 ± 0.12, 1.50 ± 0.09, and 0.91 ± 0.05 mb at 13.5 ± 0.2, 14.1 ± 0.2, and 14.8 ± 0.2 MeV incident neutron energies, respectively. Results are discussed and compared with some corresponding values found in the literature.
