DOE SCIENCE NEWS BY TOPIC: Physical Sciences
DOE provides the majority (approximately 90%) of federal support for high-energy and nuclear physics research, which uses advanced accelerator facilities as well as detectors placed underground and in space to understand the fundamental nature of matter, energy, space, time and the properties and interactions of atomic nuclei and nuclear matter.

Factors underlying nuclear fuel swelling seen at nanoscale for first time

Factors underlying nuclear fuel swelling seen at nanoscale for first time

Understanding factors that drive nuclear fuel swelling will help engineers develop higher performance fuels, which could be even safer and more efficient than those used in current nuclear energy plants. As uranium atoms split to produce energy, fission products build up within fuel rods, which impacts nuclear fuel performance inside a reactor. But, a clear picture of the size and location of these solid fission products has been elusive until now.

Predicting performance

Lignin, a low-cost byproduct of the pulp, paper and biofuels industries, can be transformed into a cheaper version of highly engineered graphite through a simple and industrially scalable manufacturing process.
