Update : Nuclear Fuel Services released a statement Friday evening about a water main breach that happened Thursday.
The company said its main fire water loop was “breached” during construction activities.
“NFS personnel immediately closed valves on the loop to stop the flow of water from the broken fire main,” the statement said. The company said the breach happened in a part of the plant where production activities are not conducted and involved water fed to the plant by the city.
“Water samples from NFS’ storm water drainage system entering Martin’s Creek immediately following and shortly after the event were well below Nuclear Regulatory Commission action levels.
NFS said the vales and drainage system storm gate will remain closed while repairs are made to the line.
Below is an earlier report:
State environmental investigators are looking into a water line break at Nuclear Fuel Services in Erwin.
A spokesman for the Nuclear Regulatory Commission said it was notified about an accidental water line rupture that happened Thursday as crews were excavating at NFS.
The company processes nuclear materials into fuel for the United States military and private clients.
That water line was used for fire prevention, and some of the water flowed off-site, according to NRC spokesman Roger Hannah.
Because the water release was unmonitored, the NRC said Nuclear Fuel Services had to notify the Tennessee Department of Evironment and Conservation and, as a result of that state notification, had to notify the NRC which oversees the facility.
A spokesperson for the Tennessee Department of Environment and Conservation told News Channel 11 it was investigating a water line rupture and release at NFS but had no further information.
Hannah said the water line break happened outside areas monitored by the NRC and would require no action by the agency.
