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.

A highly sensitive method aimed at detection of CsCl on nuclear remediation sites with isotopic selectivity was developed. The approach couples electric discharge in hydrogen as a source of dissociation of CsCl with high-resolution absorption spectroscopy using a tunable laser diode for subsequent identification of metallic cesium. The number densities of CsCl as low as 5 × 107 cm-3 can be detected with a signal-to-noise ratio better than 10 during seconds-long observation.
