TO: Mike Parker, Manager Office of Nuclear Facility Safety THRU: Rich Allen, Manager Office of Environmental Safety FROM: Larry Haskell Office of Environmental Safety DATE: June 23, 2003 RE: Dresden, Quad Cities Environmental Data 2000 - 2003 Attached to this is an MS-Excel file that details the results of IDNS analyses of environmental samples collected around the Dresden and Quad Cities Nuclear Power Stations between 2000 and 2003. All of the samples were splits of samples that Exelon collected as part of its Radiological Environmental Monitoring Program (REMP). All samples were collected under contract with Environmental Incorporated Midwest Laboratory, Inc. and analyzed by the Illinois Department of Nuclear Safety Division of Radiochemistry.

The data tables list concentrations of selected radionuclides, both reactor-produced and naturally occurring. Reactor produced radionuclides were selected because of their likelihood of being found in reactor coolant and because their half-life would permit detection several weeks after production. Uncertainties are given at the 95% confidence level. Because the concentrations in question are so close to (if not equal to) zero, random fluctuations in background may result in negative values for concentrations. While physically impossible, these negative values, when presented along with a confidence interval, are valuable for assessing method performance over the long-term. The reader will note that in most cases the confidence interval intersects the zero concentration axis. In such cases the concentration may be interpreted as being not significantly different from zero.

Water Samples Water samples were collected either weekly and composited for quarterly analysis or collected quarterly. Water samples were submitted for gross a/l, tritium and gamma spectroscopy analyses.

Milk Samples Prior to FY02, IDNS received one milk sample per quarter, where Exelon collected two samples each month at each location. Beginning in July 2002, IDNS began to receive one sample each month from each participating dairy. Milk samples were submitted for gamma spectroscopy analysis.

Sediment Samples Samples were collected twice a year, in May and October. No Quad Cities sample was collected in May 2001 because of flooding on the Mississippi River.

Sediment samples were submitted for gamma spectroscopy analysis.

Fish Samples Two species of fish were collected each May and October. Samples were prepared by technicians at Midwest Incorporated Laboratory and were taken from only the edible portions of the fish. Fish samples were analyzed for reactor-produced radionuclides using gamma spectroscopy. Because of the delay between collection and analysis, occasionally it is not possible to perform adequate measurements on the shorter-lived radionuclides (Co-58, Fe-59, Zr-95). In such instances, no data is given for those nuclides.

Vegetable Samples Two varieties of vegetables were collected annually, generally one root vegetable and one leafy green. Vegetable samples were analyzed for reactor-produced radionuclides using gamma spectroscopy.

TLD Results Results from TLD monitoring are given for the IDNS Braidwood, Dresden and Quad Cities networks. Data from the Braidwood network is included here because it overlaps with the Dresden network - many TLDs in the Braidwood network lie within the ten-mile EPZ of Dresden station. TLDs are generally exchanged quarterly. Maps of these routes are attached to the hard copy of this memo.
