SUBJECT:
INTERIM REPORT OF ANALYTICAL RESULTS FOREIGHTEEN WATER SAMPLES, BATCH TWO, FROM THE VICINITY OF THE ZION GENERATING STATION, ZION, ILLINOIS
[INSPECTION REPORT NO. 050-00295/2006-0011 (RFTA NO.06-001)
Dear Mr. Snell:
The Oak Ridge Institute for Science and Education (ORISE) received Batch Two, consisting of 18 water samples, on June 23,2006. Theses samples were collected in the vicinity of the Zion Generating Station in Zion, Illinois. The 18 water samples were analyzed for tritium to an average minimum detection concentration of 180 pCi/L using a liquid scintillation analyl.er. The chain of custody identified three water samples to be analyzed by gamma spectroscopy (GS). One water sample was identified to be analyzed for total radiostrontium iron-55, nickel-63, americium-241, and plutonium alpha isotopic analysis. 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 proccdure references are provided in the specific tables.
ORISE's Quality Control (Qc) requirements were met for these analyses. The QC files are available for jour review upon request. As more analyrical data becomes available, additional interim letter reports or a final report will be issued as requested analrses are completed.
My contact dormation is listed below. You nlayalso contact Wade Iveyat 865.576.9184 with any questions or comments.
Sincerely.
