Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.
Meeting Spotlight

WHAM: Realta gets first plasma with 17 Tesla magnets in mirror fusion test
The magnetic mirror fusion concept dates to the early 1950s, but decades ago it was sidelined by technical difficulties and researchers turned to tokamak fusion in their quest for confinement. Now it’s getting another look—with significantly more powerful technology—through WHAM, the Wisconsin HTS Axisymmetric Mirror, an experiment in partnership between startup Realta Fusion and the University of Wisconsin–Madison.

An acoustic, pulse-echo technique has been used as part of the large-scale, sodium/concrete interaction tests being conducted at Sandia Laboratories to measure the penetration of a large pool (up to 186 kg) of liquid sodium (initial temperature as high as 600°C) into a limestone concrete crucible. The acoustic data give information on the penetration, penetration rate, and condition of the sodium/concrete interface during the test. Two distinct attack modes have been seen. The first is chemical, and proceeds initially at ∼i mm/min and is of limited extent. The second is mechanical (spallation), and proceeds more rapidly (∼4 mm/min) and appears to be limited only by the reaction kinetics.
