FACILITY OPERATING LICENSE NPF-30 2008 ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT

Reference:

AmerenUE Letter ULNRC-05622, dated April 30, 2009.

The referenced letter transmitted to the NRC the 2008 Annual Radiological Environmental Operating Report (AREOR) for Callaway Plant. Please find enclosed pages supplemental to Appendix C of Part n to this report. In addition, a revision to page 11 of this report is enclosed.

As noted in the AREOR provided per the April 30, 2009 letter, the Offsite Dose Calculation Manual (ODCM) for Callaway was revised effective July 8, 2008 to require gamma spectroscopic analyses on particulate air samples in lieu of gross beta analysis. The associated plant procedure was revised to reflect the changes to the ODCM. However, the laboratory used to perform the analysis was not notified, and the required gamma spectroscopic analyses were not initially performed as intended.

The 2008 AREOR stated in Section 3.3 that the results of the gamma spectrographic analyses would be provided in a supplemental report after completion of the analyses.

The error was discovered during review of the monthly progress reports from the laboratory and preparation of the 2008 AREOR. The laboratory has been notified of the changes to the ODCM and the new analytical requirements. Further, the analyses pursuant to the ODCM requirements have been performed. Attachment 1 provides the results of the gamma spectroscopic analyses that have been completed up through and including January 1, 2009.

ULNRC-05640 July 22, 2009 Page 2 Also enclosed is a revision of page 11 of the 2008 ARBOR. This replacement page includes a statement referencing the value of the lower limit of detection (LLD) of tritium in surface water. This change is a clarification only. No change is made to the value of the mean concentration of tritium in surface water samples as reported in the 2008 ARBOR. Attachment 2 provides the original page, followed by a marked-up page that indicates the correction to that page. Attachment 3 provides a clean copy of the corrected page.

These supplemental pages to the 2008 ARBOR are submitted in accordance with Section 5.6.2 of the Technical Specifications and Appendix B to the Callaway Plant Operating License.

This letter does not contain new commitments.

If there are any questions, please contact us.

to ULNRC-05640 4.2 Program Findings (continued)

All gamma-emitting isotopes, except naturally-occurring potassium-40, in edible portions were below detection limits. The potassium-40 levels were similar at both indicator and control locations (2,867 and 2,717 pCi/kg wet, respectively).

No plant effect on the fish population is indicated.

Cesium-137 activity was detected at both indicator and control locations, at average concentrations of 523 and 231 pCi/kg dry, respectively. The cesium-137 activity is similar to or less than levels observed from 1998 through 2007, these levels are generally attributable to deposition of fallout from previous decades.

Naturally-occurring potassium-40 averaged 11,784 pCi/kg dry weight.

Analysis results for soil samples in 2008 were consistent with previously accumulated data and no plant operational effects were identified.

Surface Water The automatic sampler at location S01 was operable 100% of the time during 2008 and 94% of the time at location S02. Grab samples were taken as required.

Tritium was the only radionuclide detected in surface water samples collected during 2008. Three of twelve surface water samples collected at indicator location S02, contained measurable levels of tritium with a mean concentration of 398 pCi/L. The results are less than 2.5% of the reporting limit in surface water and well within regulatory requirements. Tritium results for location 802 are being trended along with monthly liquid H-3 releases and Missouri river flow. The 2008 results are consistent with previous operational levels and there was no significant radiological impact on the health and safety of the public or the environment.

Gamma spectroscopic analysis for surface water samples were consistent with previously accumulated data and no plant operational effects were identified.

Ground and Drinking Water (potable water)

Potable ground water from wells 0-01 and PW-01 was tested for gross beta, tritium, iodine-131 and gamma-emitting isotopes. The mean gross beta activity measured 5.5 pC ilL, ranging from 4.0 to 8.6 pCi/L and similar to levels observed from 1998 through 2007. lodine-131, tritium and gamma-emitting isotopes all measured below detection levels.

An additional twenty-one wells were added to the program in 2008 and monitored for tritium. No activity was measured above detection level (179 pCi/L) in any of the samples. Ten of the wells were monitored for gamma-emitters. No activities were detected above the respective LLDs.

Analysis results for ground water samples were consistent with previously accumulated data and no plant operational effects were identified.
