lune 28,2006 Mr. William Snell U.S. Nuclear Regulatory Commission Rcgion 111 2443 Warrenville Road lisle, 11. 60532-4351 OAK RlDQE INSTITUTE FOR SCIENCE AND EDUCATION SUBJECT FINAL LETTER RE- -AT FOR ANALYTICAL RESULTS FOR EIGHT WATER SAMPLES, BATCH FOUR, FROM THE VICINITY OF THE DRESDEN GENERATING STATION, DRESDEN, ILLINOIS
[INSPECTION REPORT NO. 050-00237/2006-0071 (RFTA NO.06-001)
Dear Mr. Snek The Oak Ridge Institute for Science and Education (ORISE) received eight water samples on May 31, 2006 which were collected in the vicinity of the Dresden Generating Station in llresdcn, Illinois. This letter report contains the origmal data submitted on June 16, 2006 and the total radiostrontium data. The chain-of-custody identified one water sample to he analyzed hy gamma spectroscopy (GS), four samples to be analyzed for tritium, and four samples to he analyzed for total radiostrontium, The sample identifications and collection data are presented in Table 1. The GS data are presented in lahle 2. The tritium data are presented in Table 3.
The total radiostrontium data are presented in Table 4. The pertinent procedure references are provided in the specific tables.
OKISEs Quality Control (QC) requirements were met for these analyses. The QC filcs are available for your review upon request.
