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.

The boson tendency to clump deuterons in palladium, which is caused by an attractive force, supplies kinetic energy to deuterons moving toward the center of the cluster. On the other hand, repulsive forces between deuterons in the cluster reduce the tendency to clump. The deuteron with kinetic energy determined from these two forces may penetrate the barrier by a tunneling effect at the center of the cluster. In this research, the transmission coefficient and power density generated from cold nuclear fusion are calculated as functions of the number of deuterons included in the cluster. When a nonlinear screened deuteron-deuteron pair potential is used as a repulsion, power densities for clusters that include 24 deuterons are 10.8 W/cm3, which gives good fit to the experimental results of 10 W/cm3 by Fleischmann et al.
