SUBJECT:

FINAL L E T T E R REPORT F O R REQUESTED ANALYSES O F NINE WATER SAMPLES, SET NINE, FROM THE INDIAN P O I N T POWER STATION, BUCHANAN, N E W YORK

[INSPECTION REPORT NO. 050-247/2006-0071 [RFTA NO. 06-0011

Dear Mr. Kottan:

The Oak k d g e Institute for Science and Education (ORISE) received set nine, which consisted of nine water samples received on August 15,2006 from the I n l a n Point Power Station in Buchanan, New York. Sample analysis was initiated based on your previous duection for h a n d h g samples from thls fachty. The final letter report was delayed untd problems associated with americium and plutonium in water were resolved by the Intercomparison Test Program conducted by the Ralological and Environmental Sciences Laboratory. Sample identification and collection data for the samples addressed in this report are presented in Table

1. Gamma spectroscopy, total rdostrontium, the hard-to-detect betas (iron-55, nickel-59/63, and tritium), technetium-99, alpha spectroscopy, plutonium-241, and carbon-1 4 data are provided in Tables 2 through 8, respectively. The pertinent procedure references are provided in each specific table.

ORISEs Quality Control (QC) requirements were met for these analyses. The QC files are available for your review upon request.

The water samples were processed using a deviation to the sample preparation procedure, SP3, Revision 4. The water samples were filtered through 0.45 micron and 0.1 micron filter papers.

An aliquot was removed for tritium and carbon-14 before acilfication. An aliquot was removed for alpha analysis and the pH was adjusted to approximately zero using concentrated nitric acid (HNO3) and a few drops of hydrofluoric acid (HF). A pH of zero and a few drops of HF should ensure that any plutonium that may be in the sample remains in solution. The remaining aliquot of each sample was adjusted to a pH of approximately 2 with concentrated HNO3.
