Uranium prices up: Could demand more than double?
Canadian uranium provider Cameco has calculated an end-of-September spot price for uranium of $82.63 per pound—the highest mark of 2025. The lowest spot price listed all year by Cameco was $64.23 per pound at the end of March, while the previous high was $78.50 per pound at the end of June.

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.
