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.

Lithium titanate breeder powder was prepared at low temperature by a solid-state mixing method. Pebbles were prepared by an extrusion and spherodization technique. The effect of binder content on separation of the extruded mass was studied. The influences of different cone mesh opening diameters (1.5, 1.0, and 0.5 mm) and spherodization speed were investigated to obtain small (0.5- to 1.5-mm) pebbles with small variations in size. It was found that Li2TiO3 could be sintered at low temperature (900°C for 6 h) with appreciable density (89%) and small grain size (1 to 3 μm) without significant closed porosity. The sphericity, pore size distribution, grain size, and crushing load strength of the sintered pebbles were also characterized. Their values were found to conform with the desired properties for use as a solid breeder.
