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.

An in-reactor test facility has been designed and built at The Ohio State University Research Reactor to evaluate the static and dynamic performance of nuclear reactor in-core sensors in environmental and neutronic conditions comparable to those expected in a high-temperature gas reactor. The primary objective for design and construction of this facility was to evaluate the performance of prototype constant-temperature power sensors. The facility can test sensors and materials over a wide range of temperatures up to 800°C, over a range of Reynolds numbers that can be varied to evaluate thermal-dynamic response, and at a reasonable neutron flux value that can be oscillated nearly 7% (up to 100 Hz eventually) to deterministically evaluate sensor transfer functions. Testing has demonstrated that this facility safely performs its desired functions with the current limitation of a 50-Hz maximum neutron flux oscillation speed.
