Caroline Nesaraja: Providing nothing but the best nuclear data

DOE/Oak Ridge National Laboratory

Nuclear physicist Caroline Nesaraja of the Department of Energy's Oak Ridge National Laboratory evaluates nuclear data vital to applied and basic sciences. Her work ensures that the scientific community has the best nuclear data for fundamental research and applications including medical isotopes, nuclear energy and national and international security.

Story tips: Urban climate impacts, materials' dual approach and healing power

Peer-Reviewed Publication

Researchers at ORNL have identified a statistical relationship between the growth of cities and the spread of paved surfaces like roads and sidewalks. // Scientists at ORNL successfully demonstrated a technique to heal dendrites that formed in a solid electrolyte, resolving an issue that can hamper the performance of high energy-density, solid-state batteries. // ORNL researchers combined additive manufacturing with conventional compression molding to produce high-performance thermoplastic composites reinforced with short carbon fibers.

Pure promethium: ORNL extracts in-demand isotope from plutonium leftovers

DOE/Oak Ridge National Laboratory
Business Announcement

An ORNL team has devised a way to extract Pm-147 from the liquid runoff left after Pu-238 production. This reduces radioactive elements that must be disposed of but also, if sustainable, could establish a domestic supply of Pm-147, for which there is already demand. The isotope is used in nuclear batteries and to measure the thickness of materials and has potential medical imaging applications.

After 20 years, physicists find a way to keep track of lost accelerator particles

DOE/Oak Ridge National Laboratory

Physicists at Oak Ridge National Laboratory have developed a measurement technique to better understand beam loss--stray particles that travel outside the confinement fields of a particle accelerator. Mitigating beam loss is paramount to realizing more powerful accelerators at smaller scales and lower costs.

Scientists use supercomputers to study reliable fusion reactor design, operation

DOE/Oak Ridge National Laboratory

A team at Princeton Plasma Physics Laboratory used two DOE supercomputers, together with a machine learning program called Eureqa, to find a new extrapolation formula from existing fusion device data to the future the ITER device. The team then completed new simulations that confirm their previous ones, which showed that in full-power ITER, the component that removes exhaust heat may be more likely to maintain its integrity than was predicted by the current trend.
