SUBJECT: INTERIM LETTER REPORT

FOR ANALYTICAL

RESULTS FOR FOUR OF 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 MI. Snell: The Oak Ridge Institute

for Science and Education (ORISE) received eight

water samples on May 31, 2006 which were coUected in the vicinity of the Dresden Generating Station

in Dresden, Ihnois. The chain-of-custody

identified

the one water sample

to be analyzed by gamma spectroscopy (GS), four samples to be analyzed for tritium, and

four samples to be analyzed for total

radiostrontium.

The four water samples were analyzed for

tritium using a liquid scintillation analyzer at

ORISE. The sample identifications and collection

data are presented

in Table 1. The GS data arc presented

in Table 2. The tritium data are presented

in Table 3. The pertinent procedure references are provided

in the specific tables. The total radiostrontium data

will be submitted

in the final letter report for hatch four. ORISE's Quality Control (QC) requirements

were met for these analyses.

The QC files are available

for your review

upon request. My contact information

is listed below.

You may also contact Wade Ivey at 865.576.9184
