The “white, stringlike” material was found among thousands of spent fuel assemblies submerged in deep pools within the site’s L Area, according to a report filed by the Defense Nuclear Facilities Safety Board, a federal oversight panel.

“The growth, which resembles a spider web, has yet to be characterized, but may be biological in nature,” the report said.
