[RFTA NO. 05-0011

Dear Mr. Kottan:

The Environmental Survey and Site Assessment Program (ESSAP)

of the Oak Ridge Institute for Science and Education (ORISE) received a concrete sample on November 4,2004 from the Yankee Nuclear Power Station in Rowe, Massachusetts that was collected on October 25,2004. The sample was analyzed as follows: by gamma spectroscopy (GS) (Procedure CPl , Revision 14), by alpha spectroscopy (AS) (Procedure APl 1 , Revision 2; Procedure CP2, Revision 12), by liquid scintillation analysis for tritium (H-3)

and carbon-14 (C-14) (Procedure AP6, Revision 14; Procedure CP4, Revision 3), by liquid scintillation analysis for nickel-63 (Ni-63), (Non-Routine Procedure AP12, Revision 3; Procedure CP4, Revision 3) and for strontium (Sr-90)

by gas-flow proportional counting (Procedure AP4, Revision1 2; Procedure CP3, Revision 2). The GS results are presented in Table 1. The AS results are presented in Table 2. The results for H-3, C-14, Ni-63, and Sr-90 have been combined and are presented in Table 3.

The request to analyze the sample for nickel-59 and iron-55 could not be met. ESSAP does not presently have procedures available for those two radionuclides in a concrete matrix.

ESSAP's Quality Control (QC) requirements were met for these analyses.

The QC files are available for your review upon request.
