Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

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 evaluation of electromagnetic (EM) loads acting on conductive structures is one of the critical problems for tokamaks. This paper focuses on the main conductive components of the Chinese Fusion Engineering Test Reactor (CFETR), which are vacuum vessel (VV) and blanket components. A multiscenario EM load-calculating simulator is developed. The simulator adopts circuit equations for the calculation of eddy current, magnetic field, and resulting EM loads acting on the VV. And for EM loads acting on the blanket components, an integral parameter method is applied. With the circuit equations and pre-obtained integral parameters implanted in the simulator, EM loads on the CFETR VV and blankets at different scenarios can be evaluated quickly. Results indicate that the simulator can be conveniently used for multiscenario and real-time EM assessment of the tokamak VV and blanket components.
