Summary:
A pair of autonomous robots will soon be driving through miles of pipes at the US Department of Energy’s former uranium enrichment plant in Piketon, Ohio, to identify uranium deposits on pipe walls.

A pair of autonomous robots developed by Carnegie Mellon University’s Robotics Institute will soon be driving through miles of pipes at the U.S. Department of Energy’s former uranium enrichment plant in Piketon, Ohio, to identify uranium deposits on pipe walls.

The CMU robot has demonstrated it can measure radiation levels more accurately from inside the pipe than is possible with external techniques. In addition to savings in labor costs, its use significantly reduces hazards to workers who otherwise must perform external measurements by hand, garbed in protective gear and using lifts or scaffolding to reach elevated pipes.

DOE officials estimate the robots could save tens of millions of dollars in completing the characterization of uranium deposits at the Portsmouth Gaseous Diffusion Plant in Piketon, and save perhaps $50 million at a similar uranium enrichment plant in Paducah, Kentucky.

…….. Shuttered since 2000, the plant began operations in 1954 and produced enriched uranium, including weapons-grade uranium. With 10.6 million square feet of floor space, it is DOE’s largest facility under roof, with three large buildings containing enrichment process equipment that span the size of 158 football fields. The process buildings contain more than 75 miles of process pipe.Finding the uranium deposits, necessary before DOE decontaminates, decommissions and demolishes the facility, is a herculean task. In the first process building, human crews over the past three years have performed more than 1.4 million measurements of process piping and components manually and are close to declaring the building “cold and dark.”

“With more than 15 miles of piping to be characterized in the next process building, there is a need to seek a smarter method,” said Rodrigo V. Rimando, Jr., director of technology development for DOE’s Office of Environmental Management……….https://www.sciencedaily.com/releases/2018/03/180320084315.htm
