LETTER REPORT FOR 27 WATER SAMPLES FROM THE VICINITY OF THE DRESDEN GENERATING STATION, DRESDEN, ILLINOIS
[INSPECTION REPORT NO. 050-00237/2007-0021 (RFTA NO.06-001)
Dear hlr. Snell:
lhc Oak Ridge Institute for Science and Education (ORISE) received 27 water samples associated with the Dresden Generating Station on February 5,2007. The samples were
- in:ilyzcd for tritium to an average minimum detectable concentration of 190 pCi/L using a Iic~~iicf sciiiullation analyzer. The chain-of-custody identified five water samples to be analyzed 11). gamma spectroscopp (GS). The sample identifications and collection data are presented in Table 1. The GS data are presented in Table 2. The tritium data are presented in Table 3. The pertinent procedure references are provided in the specific tables.
0KISI~;s Quality Control (QC) requirements were met for these analyses. The QC files are a\\-:ulable for your review upon request.
hl!- contact information is listed below. You may also contact Wade Ivey at 865.576.9184 with an!. questions or comments.
Sincerely,
