Nuclear Security and Non-Proliferation

../_images/cvt1.png

As part of the Consortium for Verification Technology (CVT), Cyclus is being used to study issues in nuclear security and non-proliferation. Cyclus is a open-source nuclear fuel cycle simulation tool developed at the University of Wisconsin-Madison (fuelcycle.org). It can be used to model the flow of nuclear material through the fuel cycle, including isotopic change due to transmutation and decay. Its flexible design enables it to also incorporate decision-making at the facility, institution, and regional levels. Cyclus can be used in the context of nuclear material production and tracking to provide synthetic datasets of fuel cycle signatures and observables that can be used to support the development of new technologies and analysis algorithms to detect illicit material diversion or production. This capability is particularly useful because diversion events are rare and very little experimental data is available in open literature.

Other research areas of interest include the incorporation of social-behavioral models to agent interactions to model expected and illicit patterns, nuclear material tracking and forensics, state level interactions that precipate, and detector sensitivity estimation.

|Cyclus| and the CVT Mission

Cyclus sits at the intersection of several thrusts of the CVT mission. Cyclus incorporates signals available to inspectors with behavorial models for diversion to inform detector development and analysis techniques.
