SUBJECT:

LETTER REPORT FOR FOUR WATER SAMPLES FROM THE VICINITY OF THE BRAIDWOOD NUCLEAR GENERATING STATION, BRAIDWOOD, ILLINOIS

[INSPECTION REPORT NO. 050-00456/2007-0041 (RFTA NO.07-001)

Dear Mr. Snell:

The Oak h d g e Institute for Science and Education (ORISE) received four water samples associated with the Braidwood Generating Station on June 1,2007. ORISE analyzed the samples, for tritium, to an average minimum detectable concentration of 190 pCi/L using a liquid scindation analyzer with one exception. Sample BD-07-03-03 had a very short count time due to the concentration of tritium in the samples. The chain-of-custody also identified one water sample to be analyzed by gamma spectroscopy

((2s).The sample identifications and collection data are presented in Table 1 . GS data are presented in Table 2 and the tritium data are presented in Table 3.

Pertinent procedural references are provided in the specific tables. ORISEs Quality Control (QC) requirements were met for these analyses. The Q C files are avdable for your review upon request.

hly contact information is listed below. You may also contact Wade Ivey at 865.576.9183 with any questions or comments.

Sincerely, Dale Condra, Manager Laboratory RDC:K,TI:km C: T. Carter, NMSS/DKMEP 7J8 E. Knox-Davin, NRC/NMSS/TWFN 8A23 E. Abelquist, ORISE S. Roberts, ORISE File 1744 I Initials
