Supplemental Report:
This supplemental corrective update to the year 2010 Vermont Yankee Annual Radiological Operating Report (AREOR) is presented to provide a revised Table 5.1 to correct minor errors in the original 2010 AREOR. These errors were discovered during a recent audit of the Radiological Environmental Monitoring Program (REMP).
Specifically, Table 5.1, REMP Annual Summary, was found to require minor changes to eight sub-sections of the table related to summarization of data collected from various environmental sample locations. The attached, revised Table 5.1 corrects these summarization errors. Changes to the table are highlighted in bold font. A summary of the corrections is provided below:
Radium-226 (Ra-226) for Air Particulate(Location with the Highest Annual Mean) was revised to indicate that Tyler Hill Road (Station 15) had a slightly higher mean, 0.0333 picocuries per cubic meter of air, than River Station (Station 11) with an annual mean of 0.0332 picocuries per cubic meter of air. All values for Radium-226 were below detection limits for each of these stations.
This change was made on page 27 of the table.
Manganese-54 (Mn-54) for Sediments (Control Location) was revised to indicate that there were no detections of the radionuclide, as indicated by the data for these locations. The Control Location Mean format was revised to be mathematically consistent with other Means in the table (from "49" to "48.8"). The table information was revised from "(2/2)" was changed to "(0/2)" on page 31 of the table.
Cesium-134 (Cs-134) for Sediments (Control Location and Location with the Highest Annual Mean) was revised to be mathematically consistent with other Means in the table (from "41" to "40.9" and from "71" to "70.5").This change was made on page 31 of the table.
Manganese-54 (Mn-54) for Sediments (Control Location) was revised to indicate that there were no detections of the radionuclide, as indicated by the data for these locations. The table information was revised from "(2/2)" was changed to "(0/2)" on page 31 of the table.
Cesium-137 (Cs-1377) for Sediments (Control Location) was revised to be mathematically consistent with other Means in the table (from "68" to "68.0"). This change was made on page 32 of the table.
Uranium-238 (U-238) for Sediments (Indicator, Control and Location with the Highest Annual Mean) was revised to indicate that there were no detections of the radionuclide, as indicated by the data for these locations. The ratios for these three categories were corrected as follows; "(34/34)"
was changed to "(0/34)", "(2/2)" was changed to "(0/2)" and "(2/2)" was changed to "(0/2)". Also, in this section, less than symbols "<" were omitted from the range data and these have been restored in this revision. These changes were made on page 32 of the table.
Americium-241 (Am-24) for Sediments (Indicator Location) was revised to reflect the absence of detection of the radionuclide, as indicated by the data for these locations. The table information was revised from "(2100/12700)" to "(<5.39/<188)" on page 32 of the table.
Strontium-90 (Sr-90) for Milk (Control Location) was revised to reflect the detections of the radionuclide, as indicated by the data for this location. Four of the eleven samples collected at these locations were found to contain detectable Sr-90. The table information was revised from a range of"<0.481/<2.45" to a range of "<0.481 to 2.45" on page 37 of the table.
Page 2 of 3
Strontium-90 (Sr-90) for Fish (Indicator, Control and Location with the Highest Annual Mean) was revised to reflect the detections of the radionuclide, as indicated by the data for this location.
The Indicator Locations ratio of detections to total samples analyzed was revised from "(0/16)" to
"(3/16)". The Control Location ratio of detections to total samples analyzed was revised from
"(0/16)" to "(6/16)". The Location with Highest Annual Mean ratio of detections to total samples analyzed was revised from "(0/16)" to "(6/16)". Additionally, less than (<) symbols were removed from the upper range for each of the Control and Location with Highest Annual Mean columns to reflect the data collected from these fish samples. These changes were made on page 43 of the table.
None of the changes made in Table 5.1 alter the conclusion that no radionuclides attributed to Vermont Yankee plant operations were found in any REMP sample locations during year 2010.
