ORNL–General Atomics partnership on ceramic matrix composites
A memorandum of understanding has been signed by Oak Ridge National Laboratory and General Atomics Electromagnetic Systems (GA-EMS) with the objective of working together on advanced ceramic matrix composite materials for applications in extreme environments. Materials that can withstand extreme temperatures, radiation, corrosion, and mechanical stress are required in aerospace, defense, energy, and other sectors.
According to the agreement, the San Diego–based GA-EMS will use resources from ORNL’s Manufacturing Demonstration Facility to develop “scalable, efficient manufacturing techniques for extreme environment materials including precursors, fibers, composites, and coatings utilized in carbon/carbon (C/C), carbon/silicon carbide (C/SiC), and SiC/SiC composite systems.”

Peacock is a three-dimensional, continuous-energy, Monte Carlo code developed by Studsvik Scandpower, Inc. (SSP). Peacock is intended to augment the current offerings from SSP to model advanced, next-generation nuclear reactors. The code allows modeling of general geometries and includes capabilities for depletion. Peacock is designed for efficient use on commonly available, consumer-grade computing architectures and includes shared-memory (OpenMP) parallelism.
In addition to a presentation on the theoretical foundations of the Peacock methodologies, attendees will be running Peacock cases. By running Peacock, attendees will be able to investigate reactor physics phenomena (e.g., temperature dependences, depletion, etc.). Participants will need to bring their own laptop with a ssh client to access the Peacock computing resources that will be furnished by SSP.
No licensing is required as no code or executables will be provided to attendees. Attendees will only be able to run Peacock on resources provided by SSP.
