==Dear Mr. Shetler:==
==Dear Mr. Shetler:==
This letter presents the results of laboratory analyses of soil samples collected from beneath the spent fuel pool floor of the Rancho Seco Nuclear Generating Station between October 25 and 28, 2004. The analyses were conducted by Oak Ridge Institute for Science and Education (ORISE), Environmental Survey and Site Assessment Program, on behalf of the NRC. The NRC's analysis of the sample results is provided in Enclosure 1 to this letter and a copy of the ORISE report is provided in Enclosure 2.
October 25, 2004


Other than comparing the enclosed results with the split samples that were collected by your staff at the same time, no response is requested from you at this time. The NRC may conduct an integrated evaluation of the ORISE sample results with your split sample results in the future. If so the results will be included in a future inspection report.

==Dear Mr. Atwater:==
The Environmental Survey and Site Assessment Program (ESSAP) of the Oak Ridge Institute for Science and Education (ORISE) received eight soil samples on November 2,2004 that were collected from October 25,2004 through October 28,2004 at Rancho Seco - SMUD. Four of the samples were received in Marinelli beakers and were analyzed for cobalt-60 and cesium-137 by gamma spectroscopy (GS) (Procedure CP1, Revision 14). The remaining four samples were received in scintillation vials and were analyzed for carbon-14 and tritium by liquid scintillation analysis (LSA) (Procedure AP6, Revision 14; CP4, Revision 3). The GS and LSA data are presented in Tables 1 and 2, respectively.
 
ESSAP's Quality Control (QC) requirements were met for these analyses. The QC files are available for your review upon request.
 
This Ietter report was delayed due to problems with the counting and processing instrumentation used in the carbon-14 and tritium analyt~cal process. We apologize for this delay and hope that the delay has not placed an undue burden on your report process.


In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, Enclosures 1 & 2, and your response (if any) will be made available electronically for public inspection in the NRC Public Document Room or from the NRC's document system (ADAMS),

accessible from the NRC Web site at httD://www.nrc.qov/readinq-rm/Adarns.html. To the extent possible, your response should not include any personal privacy, proprietary, or safeguards information so that it can be made available to the public without redaction.


Please note that on October 25, 2004, the NRC suspended public access to ADAMS, and initiated an additional security review of publicly available documents to ensure that potentially sensitive information is removed from the ADAMS database accessible through the NRC's web site. Interested members of the public may obtain copies of the referenced documents for review and/or copying by contacting the Public Document Room pending resumption of public access to ADAMS.

Dear Mr. Atwater:

The Environmental Survey and Site Assessment Program (ESSAP) of the Oak Ridge Institute for Science and Education (ORISE) received eight soil samples on November 2,2004 that were collected from October 25,2004 through October 28,2004 at Rancho Seco - SMUD. Four of the samples were received in Marinelli beakers and were analyzed for cobalt-60 and cesium-137 by gamma spectroscopy (GS) (Procedure CP1, Revision 14). The remaining four samples were received in scintillation vials and were analyzed for carbon-14 and tritium by liquid scintillation analysis (LSA) (Procedure AP6, Revision 14; CP4, Revision 3). The GS and LSA data are presented in Tables 1 and 2, respectively.

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

This Ietter report was delayed due to problems with the counting and processing instrumentation used in the carbon-14 and tritium analyt~cal process. We apologize for this delay and hope that the delay has not placed an undue burden on your report process.
