The journey of the U.S. fuel cycle
Craig Piercycpiercy@ans.org
While most big journeys begin with a clear objective, they rarely start with an exact knowledge of the route. When commissioning the Lewis and Clark expedition in 1803, President Thomas Jefferson didn’t provide specific “turn right at the big mountain” directions to the Corps of Discovery. He gave goal-oriented instructions: explore the Missouri River, find its source, search for a transcontinental water route to the Pacific, and build scientific and cultural knowledge along the way.
Jefferson left it up to Lewis and Clark to turn his broad, geopolitically motivated guidance into gritty reality.
Similarly, U.S. nuclear policy has begun a journey toward closing the U.S. nuclear fuel cycle. There is a clear signal of support for recycling from the Trump administration, along with growing bipartisan excitement in Congress. Yet the precise path remains unclear.

This workshop will demonstrate the usage of MOOSE-based and MOOSE wrapped applications, which are used for high fidelity analysis of several advanced reactor designs. The training will focus on multiscale and multiphysics analyses of pebble bed reactors. The CFD codes NekRS, Pronghorn, and Cardinal will be demonstrated along with Griffin, the NEAMS reactor transport application. The MOOSE’s Multiapp and Transfer systems will be addressed in detail and used for coupling these applications to capture critical physics-based feedback mechanisms critical to the passive safety features of advanced reactors. The workshop is a joint effort between Argonne and Idaho National Laboratories researchers.
