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.

Metal organic decomposition (MOD) Er2O3 coating for tritium permeation barrier was fabricated on two ferritic steels with dip-coating method. The interfacial layers, which were formed by the oxidation of the substrates, were found under the coating with different compositions and thickness according to the elemental depth profile of XPS. Their formations depended on the substrate materials (JLF-1: Fe-9Cr-2W based reduced activation ferritic/martensitic steel; SUS430: 18Cr based commercial ferritic steel) and the baking atmosphere (air or Ar). The main reason could be selective oxidation of main elements in the substrates at high temperature with the different baking atmosphere. For the coated JLF-1 samples, the surface smoothness and the hydrogen barrier performance of Er2O3 coatings were improved significantly by changing the baking atmosphere from air to Ar. The composition change in the oxidized interfacial layer from iron oxide to chromium oxide may be the reason for the improved surface smoothness and permeation barrier performance.
