The Denethor supercomputer is designed to provide increased computational capability for the SNRI Nuclear Research Program in support of ever-demanding workloads, e.g., increasing geometric and physics fidelities while maintaining expectations for total time to solution. The capabilities of Denethor are required for supporting the SNRI's research program's certification and assessments.
Denethor is intended for capability computing used in a wide range of applications from computational physics to physical security.
Nuclear reactors present a unique challenge to researchers interested in building new ones, or even just making existing reactors more efficient. By their very nature, it is extremely difficult to directly observe what is happening in an operating reactor. Modeling and simulation provides the ability for scientists and engineers to not only understand what is happening, but how it is happening in these environments.
The modeling technology run on a supercomputer called the Virtual Reactor (VR), which will allow scientists and engineers to stand in the center of a virtual reactor, observing coolant flow, nuclear fuel performance, and even the reactor's response to changes in operating conditions.
This year, SNRI worked with a local vendor to develop a model that would simulate attacks of various types of threats. The model (completed under the Glorfindel project with Cooperzino and AAEA) measured the effectiveness of response plans and current protective force shift deployments. The model was able to define new vulnerabilities not previously perceived as well as mark areas of strength.
The following example demonstrates the potential pathway an adversary composed of a passive insider and 6 active outsider could take against the established SNRI physical protection system and other security measures.
Glorfindel is a joint physical protection project between SNRI and Cooperzino to develop fixed asset and transportation security models. The purpose of the collaboration is to ensure that material and information in storage, intrasite transfers, and intersite transfers all have the same level of protection.
