SUBJECT:
ANALYTICAL RESULTS FOR FOUR WATER SAMPLES FROM THE VICINITY OF THE BRAIDWOOD NUCLEAR GENERATING STATION, BRAIDWOOD, ILLINOIS
[INSPECTION REPORT NO. 050-456/06-0081 (RFTA NO.06-001)
Dear Mr. Snek The Oak Ridge Institute for Science and Education (ORISE) received an electronic mail on March 23,200G requesting total radiostrontium (Sr) and iron-55 (Fe-55) analysis on four of the ten water samples received on December 30,2005 from the vicinity of the Braidwood Generating Station. On March 24,2006 during a phone call to ORISE, the request was expanded to include Americium-241 (Am-241), Plutonim-238,239/240 (Pu-238,239/240),
and nickel-63 (Ni-63). The ten water samples were originally analyzed by gamma spectroscopy for gamma emitting radionuclides and by liquid scintillation for tritium. The letter report for the original analyses was submitted to John House on January 13,2006. Total radiostrontium was analyzed by low background beta counting (Procedures AP4, Revision 13; CP3, Revision 2). Fe-55 and Ni-63 were analyzed by liquid scindation analysis (Procedures AP13, Revision 4; AP12, Revision 4; and CP4, Revision 3). Am and Pu were analyzed by alpha spectroscopy (AS)
(Trocedures API 1, Revision 3; CP2, Revision 12). The sample identifications and collection data are presented in Table 1. ?he AS, Fe, Ni, and Sr data are presented in Tables 2 through 5, respectively.
Samples 1682WOO67 and 1682WOO69 are from the same sample collection site but were collected on different days. An aliquot of 1682W0067 was used in the Sr analysis, but subsequently the rest of the sample was cross contaminated with another sample. Aliquots from 1682W0069 were used in the AS, Fe, and Ni analyses.
ORISE's Quality Control (QC) requirements were met for these analyses. The QC files are available for your review upon request RECEIVED APR 1 8 2006
