A wispy white substance has been discovered clinging to submerged racks of spent fuel assemblies stored at the Savannah River Site.
On Friday the Augusta Chronicle noted a report to federal regulators describing a white, stringy material on the racks at the national lab's L Area. Scientists collected a small sample and plan to study it further. The spider-web-like material has not been identified, but the lab suggested it may be biological.
A spokesman for the South Carolina lab told the Chronicle the substance didn't appear to be harming anything in the tank, which is filled with fuel assemblies from various research reactors.
