Containers for Yucca Mountain
This cutaway of a drift for the waste disposal facility project at Yucca Mountain in the Nevada Desert shows three types of waste container: fuel assemblies for pressurized water reactors and boiling water reactors (in the foreground and background), and packages of high-level waste (in the middle). In blue you can see the titanium shields used to protect the containers from any water that drips from the drift ceiling. The site has a desert climate but the layers of tuff (compacted volcanic ash) in Yucca Mountain are not as impermeable as clay. That is one of the reasons why the project was abandoned
