ANALYTICAL RESULTS FOR 41 WATER SAMPLES IN BATCH TWO FROM T H E VICINITY OF T H E BYRON GENERATING STATION, BYRON, ILLINOIS [INSPECTION REPORT NO. 05000454/2006-0031 (RFTA NO.06-001)

Dear M r . Snell:

'Ihc Oak k d g e Institute for Science and Education (ORISE) received 41 water samples in Batch Two on April 12,2006 that were collected in the vicinity of the Byron Generating Station in Byron, Illinois. This water sample sct was received at the same time as two water sample sets from the Braidwood facility.

'The laboratory has been instructed that samples from the Braidwood facility have higher priority a i d the samplrs from the Byron facility were analyzed after the Braidwood sample sets. The samples were analyzed for tritium using a liquid scintillation analyzer (Procedures A1'2, Revision 15 and CP4, Revision 3). The chain of custody identified six water samples to be analyzed by g;lmma spectroscopy (GS)

(l'rocedure CPl, Revision 15). The sample identifications and collection data are presented in Table 1.

'l'hc GS data arc presented in Table 2. The tritium data arc presented in Table 3.

ORISE's Quality Control (QC) requirements were met for these analyses. 'Ihe QC files are available for your review upon request.

My contact information is listcd below. You may also contact Wade h e y at 865.576.9184 with any questions or comments.

Sincerely.
