Researchers examine use of cosmic-ray radiography on damaged
reactor cores
Researchers from Los Alamos National Laboratory have devised
a method to use cosmic rays to gather detailed information from inside the
damaged cores of the Fukushima Daiichi nuclear reactors, which were heavily
damaged in March 2011 by a tsunami that followed a great earthquake.
In a paper in Physical Review Letters, researchers compared
two methods for using cosmic-ray radiography to gather images of nuclear
material within the core of a reactor similar to Fukushima Daiichi Reactor No.
1. The team found that Los Alamos’ scattering method for cosmic-ray radiography
was far superior to the traditional transmission method for capturing
high-resolution image data of potentially damaged nuclear material.
