. Gaseous Effluents The quantity of radioactive material released in gaseous effluents during the reporting period is summarized in Table A1. The quarterly and annual sums of all radionuclides discharged in gaseous effluents are reported in Tables A1A and A1B. All gaseous effluent releases are considered to be ground level.

14 C has been added to the gaseous effluent tables. Based on new Nuclear Regulatory Commission guidance, beginning with the 2010 report, all U.S. nuclear power plants will include 14 C doses in their ARERR.

14 C is a naturally occurring isotope of carbon. It is produced continuously by cosmic ray interaction with oxygen and nitrogen in the upper atmosphere. Carbon dating, using 14C, is a very reliable tool in dating of organic matter up to 30,000 years old. 14C is also a byproduct of nuclear weapons testing and nuclear power generation. Nuclear weapons testing in the 1950s and 1960s significantly increased the amount of 14C in the atmosphere. The amount of 14C produced by nuclear power generation is much less than that produced naturally or from weapons testing.1 The level of 14C discharged in gaseous effluents has not increased. Improvements in nuclear power plant operation have significantly reduced the overall quantity of radioactivity released in plant effluents. One consequence of this success is that for most nuclear plants 14C may now be a principle nuclide as defined in Regulatory Guide 1.21, revision 2, and as such must be reported in the ARERR.

The radiation dose to the public from all radionuclides, including 14C, continues to be a small fraction of the regulatory limits.

The amount of 14C released in gaseous effluents was calculated as described in EPRI Technical Report 10211062 and is documented in HPCI 1102.3

. Liquid Effluents The quantity of radioactive material released in liquid effluents during the reporting period is summarized in Table A2. The quarterly and annual sums of all radionuclides discharged in liquid effluents are reported in Table A2A. All liquid effluents were discharged in batch mode; there were no continuous liquid discharges for the reporting period. Dilution by the Missouri River, in the form of the near field dilution factor, is utilized in the ODCM dose calculation methodology.

. Solid Waste Storage and Shipments The volume and activity of solid waste shipped for disposal is provided in Table A3. Table A3 is presented in the format of rev. 1 to Regulatory Guide 1.21 because the data is not readily available in the format recommended by rev. 2 to Regulatory Guide 1.21.

. Dose Assessments The annual evaluation of dose to the Member of the Public is calculated in accordance with the methodology and parameters in the ODCM and is reported in Tables A4 and A5.

5.1 Table A4, Dose Assessments, 10 CFR 50, Appendix I The dose assessments reported in Table A4 were calculated using the methodology and parameters in the ODCM and demonstrate compliance with 10 CFR 50, Appendix I. The gamma air dose and beta air dose were calculated at the nearest Site Boundary location with the highest value of X/Q, as described in the ODCM. The maximum organ dose from gaseous effluents was calculated for the ingestion, inhalation, and ground plane pathways at the location of the nearest resident with the highest value of D/Q, as described in the ODCM. The organ dose includes the dose from 14C.

5.2 Table A5, EPA 40 CFR 190 Individual in the Unrestricted Area The dose assessments reported in Table A5 are the doses to the Member of the Public from activities within the Site Boundary. A large portion of the residual land of the Callaway Site is managed by the State of Missouri Conservation Department as the Reform Wildlife Management Area. As described in the ODCM, the dose from gaseous effluents, plus the dose contribution from direct radiation sources, including dose from outdoor water storage tanks, direct dose due to 16N from operation of the unit, and organ dose from 14C. The dose assessments in Table A5 demonstrate compliance with 10 CFR 20.1301(e) and 40 CFR 190.

. Supplemental Information 6.1 Abnormal Releases or Abnormal Discharges There were no abnormal releases or abnormal discharges during the reporting period.

6.2 Non routine Planned Discharges There were no non routine planned discharges during the reporting period.

6.3 Radioactive Waste Treatment System Changes Modification 060102 installed diaphragms in the Reactor water Holdup Tanks (RHUTs). The diaphragms allow degassing of the water. The fission product gas is stored in the Waste Gas 3 Decay Tanks (WGDTs) for holdup prior to discharge. This change should reduce the quantity of noble gases discharged in gaseous effluents.

Enclosure to ULNRC-05784 Page 5 of 40 There were no other major changes to the liquid or gaseous radwaste treatment system during the reporting period.

6.4 Annual Land Use Census Changes The evaluation of the 2010 Land Use Census is documented in HPCI 1003. There were no changes in the location of the nearest resident or the location of the nearest vegetable garden with the highest value of D/Q. There were no milk sample providers identified and the Callaway Plant continues to sample green leafy vegetation in lieu of milk. There were no changes in the green leafy vegetation sample locations.

6.5 Effluent Monitoring System Inoperability Specifications covering the Limiting Conditions of Operations (LCO) for effluent monitoring instrumentation are provided in Radiological Effluent Control (REC) 16.11.1. 3 and 16.11.2.4.

The ACTION statement implements provisions that when taken as specified complete requirements to demonstrate functionality. When the required ACTION is not met, the equipment is removed from service or declared non functional. This report provides explanation for periods of time when inoperability occurred.

GHRE0010B, Radwaste Building Wide Range Gaseous Effluents Monitor, Not Functional for More than 30 Days On 12/23/2009, an instrument loop calibration was completed for the wide range Radwaste Building ventilation monitor, GHRE0010B. The check source functioned satisfactorily for the low range detector, the mid range detector, and the high range detector. However, when the calibration was completed the high range detector channel would not return from blue status to green status (blue status means an operate failure alarm on the channel). This resulted in a condition where the monitor was correctly performing its indication and ODCM sampling for the low and mid range channels, but the high range channel could not be confirmed functional.

Following a review by the Engineering Department and the Control Room, GHRE0010B was returned to service on 12/23/2009 with the high range channel still in operate failure status.

The low range channel was operating normally. It was thought that the ODCM setpoint providing alarm and isolation was in the range of the low range channel, therefore the monitor met the operability requirements of REC 16.11.2.4 without a functional high range channel. This reflects a basic misunderstanding of the monitor design: The ODCM setpoint and the alarm and isolation functions are provided by the effluent channel, not the detector channels. An algorithm is used to determine which channel low, mid, or high range provides the input to the effluent channel. A new work request, job 09008605 was created to trouble shoot the operate failure condition on the high range channel along with a corrective action request (CAR 200910504) to document the status.

4 Monitor GHRE0010B operated in this condition until March 5, 2010, when the vendors analysis of certain parameters indicated the operate failure status on the high range channel was due to

Enclosure to ULNRC-05784 Page 6 of 40 timing issues which affected the algorithm used to determine which channel provides the input to the effluent channel. This resulted in CAR 201001963 to evaluate functionality of GHRE0010B. Although GHRE0010B was correctly monitoring in accordance with REC 16.11.5.2, GHRE0010B was declared non functional because it was not certain that the algorithm would always select the correct detector for input to the effluents channel.

Under on site direction by the vendor, the monitor database was reset and a new high range channel check source was installed. The high range channel was subsequently returned to normal and the monitor was returned to functional status on March 18, 2010. A review of the data for the effluents channel from 12/23/2009 3/18/2010 indicates the monitor output was stable during that time period and there are no indications the algorithm selected the wrong channel for input to the effluent channel.

HBLT2004, Discharge Monitoring Tank A Level Transmitter, Not Functional for More than 30 Days On July 21, 2010, during surveillance testing of HBLT2004, it was noted that the as found condition was not within calibration for the lower trip and rest values. The unit was slow to respond which is indicative of a problem with the sensing bellows. This conclusion was supported by sludge fluid present when the plug was removed at a test connection. HBLT2004 was declared non functional and entered into the Equipment Out of Service Log (EOSL). The EOSL entry correctly stated that there was a 30 day limit on the ACTION statement.

There was a design change already planned and a job written to replace the whole transmitter.

Repair of HBLT2004 was tied to that job. Pursuant to ACTION 33, alternate methods were implemented to allow discharges to continue. There is no time limit stated in ACTION 33, however REC 16.11.1.3, ACTION b states that releases can continue for 30 days provided the ACTION is taken. The job for replacing the whole transmitter was planned for September 30, 2010. Those responsible for planning the work did not understand at the time that there is a 30 day limit on the ACTION statement.

On August 18, 2010, CAR 201007873 was written stating that HBLT2004 exceeded the 30 day limit stated in REC 16.11.1.3, ACTION b. HBLT2004 was returned to functional status on September 30, 2010.

6.6 Offsite Dose Calculation Manual Changes There were no changes to the Offsite Dose Calculation Manual during the reporting period.

6.7 Process Control Program Changes Administrative changes were made to APAZZ01011, Process Control Program due to organizational realignment. There were no substantive changes to the Process Control Program 5 during the reporting period.

Enclosure to ULNRC-05784 Page 7 of 40 6.8 Corrections to Previous Reports Corrections to the 2008 and 2009 Annual Radiological Effluent Release Reports are provided in Appendix C and Appendix D, respectively. These changes are necessary because the dose from 63 Ni in gaseous effluents was not included in the original reports, although the quantity of 63Ni was properly reported in each report.

6.9 Other Information Related to Radioactive Effluents Meteorological Joint Frequency Tables for the monitoring period are attached as Appendix B.
