“A group of professionals having fun in the fields of decommissioning and environmental sciences for the nuclear industry.”

That’s how the ANS DESD describes itself on its website. The focus of this professional division is the development and use of skills and technologies needed for the optimal management of the end-­of-­life care (decommissioning, decontamination, and remediation), long-­term surveillance, and maintenance of nuclear installations, materials, facilities, and sites.

A team of scientists from the United Kingdom’s University of Bristol were given access to the Chernobyl nuclear power plant in Ukraine, advancing a project to train robots and artificial intelligence systems to measure radiation and create 3D maps.

A slideshow of the team’s visit to Chernobyl’s Unit 4 control room and New Safe Confinement structure, where they deployed radiation mapping and scanning sensors, including a LIDAR-equipped robot call Rooster, appears on Gizmodo.

Savannah River Nuclear Solutions (SRNS), the management and operations contractor for the Department of Energy’s Savannah River Site, has torn down a large industrial cooling tower at the site’s D Area complex. The cooling tower, built in 1952, is one of more than 30 structures being removed from SRS’s D Area as the DOE works to reduce the site’s footprint.
