OAK RIDGE INSTITUTE FOR SCIENCE AND EDUCATION August 17,2006 Mr. James Cameron US. Nuclear Regulatory Commission Region 111 2443 Warrenvdle Road Lisle, IL 60532-4351 SUBJECI:
ANALYTICAL RESULTS FOR THREE WATER SAMPLES IN BATCH SIX FROM THE VICINITY OF THE BYRON GENERATING STATION, BYRON, ILLINOIS
[INSPECTION REPORT NO. 050-00454/2006-0041 (RFTANO.06-001)
Dear Mr. Cameron:
The Oak Ridge Institute for Science and Education (ORISE) received Batch Six, consistiig of three water samples on August 2,2006 that were collected in the vicinityof the Byron Generating Station in Byon, Illinois. The samples were analyzed for tritium to a minimum detectable concentration of 180 p W L using a liquid scintillation analpr. The chain-of-custodyidentified one watersample to be analyzed by gamma spectroscopy (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.
ORISEs Quality Control (QCJ requirements were met for these analrses. The Qc files are available for p u r review upon request.
My contact information is listed below. You m y also contact Wade Ivcy at 865.576.9 184 with any questions or comments.
