For example, the typical ratio of Uranium-235 to Uranium-238 found in nature is 0.00725, but the ratio in Nolichucky sediment and water is 0.015. Ketterer's team also found that mollusks in Davy Crockett Lake, a popular fishing spot on the Nolichucky, show uranium signatures that matched those in the water.via common dreams
The concentrations of enriched uranium that Ketterer found are low and do not exceed federal drinking water standards. But as Ketterer pointed out during a press conference last week, the federal water discharge permit for NFS says the facility is not supposed to be releasing any enriched uranium.
Ketterer presented his findings to the Nuclear Regulatory Commission (NRC) last week during a public hearing about a proposed 40-year license renewal for the NFS facility, the Greeneville Sun reported.
In 2006, there was a leak of highly enriched uranium from the NFS plant. In response, the NRC issued an order modifying the company's special nuclear materials license that cited a "deficient safety culture" at the facility, the Knoxville News-Sentinel reported in 2007.
The order detailed six instances in 2005 and 2006 in which NFS personnel violated NRC regulations. The spill itself resulted in eight separate violations, including failure to notify NRC in a timely manner, and failure to meet safety requirements for a criticality accident, which could lead to the release of a deadly amount of radiation.
In 2006, the NFS facility also failed to meet performance requirements in an exercise designed to test a plant's response to an attack, and there were three instances in 2005 and 2006 where the company failed to secure special nuclear material.
NFS is a subsidiary of the Charlotte, N.C.-based Babcock and Wilcox Co., which provides design, engineering, construction and management services for nuclear power plants.

NFS again, ISS tells me what my government wants to hide from me ...
