Collaborators from the University of Wisconsin-Madison (UW-Madison) and Oak Ridge National Laboratory (ORNL) have taught computers to quickly and consistently spot and analyze microscopic radiation damage to materials being considered for nuclear reactors.

UW-Madison's Wei Li and Dane Morgan, with ORNL's Kevin Field, developed a machine learning algorithm to make a neural network capable of rapidly mining electron microscopy images of radiation-exposed materials to identify a specific type of damage, known as dislocation loops.

Following training with 270 images, the neural network, in conjunction with a cascade object detector, correctly detected and classified about 86% percent of dislocation loops in a series of test images, versus 80% found by human experts.
