Annual Radioactive Effluent Release Report - 2010

SAN ONOFRE NUCLEAR GENERATING STATION Annual Radioactive Effluent Release Report 2010 January - December

PREFACE San Onofre Nuclear Generating Station is located next to San Onofre State Beach, adjoining Camp Pendleton Marine Corps Base, in San Diego County, 64 miles south of Los Angeles, California. There are two operating pressurized water reactors with a total rated capacity of 2254 net megawatts electrical.

Unit 1, rated at 410 net megawatts electrical, was supplied by Westinghouse Electric Company and began commercial operation on January 1, 1968. The unit was permanently shutdown on November 30, 1992. By August 31, 2004, all fuel was transferred to the Independent Spent Fuel Storage Installation (ISFSI). As of November 29, 2006, all remaining monitored effluent pathways were permanently removed from service. Unit 1 is owned by Southern California Edison (80%) and San Diego Gas and Electric (20%).

Unit 2 and Unit 3 were supplied by Combustion Engineering, Inc., with turbine generators supplied by G.E.C. Turbine Generators, Ltd., of England. The units began commercial operation on August 18, 1983, and April 1, 1984, respectively and are rated at 1127 net megawatts electrical each. The twin units are owned by Southern California Edison (78.21%), San Diego Gas and Electric (20%), and the City of Riverside (1.79%).

Effective December 29, 2006, the City of Anaheim transferred its ownership interests in San Onofre Units 2 and 3 and the entitlement to the Units 2 and 3 output, to Southern California Edison Company, except that it retains its ownership interests in its used nuclear fuel and Units 2 and 3's independent spent fuel storage installation located on the facility's site. The City of Anaheim retains financial responsibility for used fuel generated during its ownership and for a portion of the Units 2 and 3 decommissioning costs. The City of Anaheim remains a licensee for purposes of its retained interests and liabilities.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT - 2010 SAN ONOFRE NUCLEAR GENERATING STATION SECTION A. INTRODUCTION This Annual Radioactive Effluent Release Report summarizes the gaseous and liquid radioactive effluent releases and radwaste shipments made from the San Onofre Nuclear Generating Station. It will also summarize the radwaste shipments from the decommissioning of Unit 1. This report is prepared in the general format of USNRC Regulatory Guide 1.21 and includes:

1. Quarterly Summaries of Gaseous and Liquid Effluents for "Continuous" and "Batch" Modes of Release
2. Percent of Applicable Limits
3. Estimated Total Percent Error
4. Lower Limit of Detection Concentrations
5. Batch Release Summaries
6. Previous Radioactive Effluent Release Report Addendum
7. Radwaste Shipments
8. 10 CFR 50 Appendix I Requirements
9. Changes to Offsite Dose Calculation Manual ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT - 2010 SAN ONOFRE NUCLEAR GENERATING STATION SECTION B. GASEOUS EFFLUENTS Table 1A, "Gaseous Effluents-Summation of All Releases," provides a detailed listing of gaseous effluents released quarterly in four categories: fission and activation gases, iodine-1 31, particulates with half-lives greater than eight days, and tritium. Listed for each of the four categories are:

(1) the total curies released (2) the average release rate (3) the percent of applicable limit (4) the estimated total error In addition, the particulate category lists the gross alpha radioactivity released for each quarter.

The methodology used to calculate the percent of Applicable Limit is presented in Section F of this report. The methodology used in Table 1A to calculate the estimated total error is presented in Section G of this report.

Table 1B, "Gaseous Effluents-Elevated Release," has not been included in this report since San Onofre Nuclear Generating Station does not conduct elevated releases.

Table 1C, "Gaseous Effluents-Ground Level Releases," provides the systematic listing by radionuclide for the quantity of radioactivity released in three categories: fission gases, iodines, and particulates.

The total radioactivity for each radionuclide is listed for each quarterly period by both "continuous" and "batch" modes of release.

Waste gas decay tank releases are considered to be "batch" releases. Containment purges and plant stack releases are considered to be "continuous" releases.

Table 1D, "Gaseous Effluents-Lower Limit of Detection," provides a listing of lower limit of detection concentrations for radionuclides not detected in Tables 1A and 1C.

Table 1E, "Gaseous Effluents-Radiation Doses at the Site Boundary," provides a quarterly summary of doses at the site boundary for this report period.

Table 1F, "Gaseous Effluents-Batch Release Summary," provides summary information regarding batch releases conducted during this report period from San Onofre Nuclear Generating Station.

  • SCE maintains contracts with Duratek for volume reduction services. The processed volume was shipped from the EnergySolutions Duratek facilities to EnergySolutions Utah Burial Site using 34 shipments. Those 34 shipments included waste from other generators. SCE's waste volume was a fraction of the total waste volume of these shipments.

SEC maintains contracts with PermaFix/DSSI for volume reduction services. The waste was destroyed (burned) per applicable regulations. Due to the method of destruction, the residual waste becomes PermaFix/DSSl secondary waste which was disposed of at the EnergySolutions Utah Burial Site.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT - 2010 SAN ONOFRE NUCLEAR GENERATING STATION SECTION G. ESTIMATION OF ERROR Estimations of the error in reported values of gaseous and liquid effluents releases have been made.

Sources of error for gaseous effluents - batch releases are:

(1) tank volumes (2) sampling (3) counting (4) calibration Sources of error for gaseous effluents - continuous releases are:

(1) fan flow rate (2) sampling (3) counting (4) calibration (5) differential pressure drop Sources of error for liquid effluents - batch releases are:

(1) tank volumes (2) sampling (3) counting (4) calibration Sources of error for liquid effluents - continuous releases are:

(1) dilution flow rate (2) sampling (3) counting (4) calibration These sources of error are independent, and thus, the total error is calculated according to the following formula:

Total Error 2E + 2 + c2 2

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT - 2010 SAN ONOFRE NUCLEAR GENERATING STATION SECTION H. 10 CFR 50 APPENDIX I REQUIREMENTS Table 1 in Section H presents the quarterly and annual maximum dose to an individual. Six different categories are presented:

(1) Liquid Effluents - Whole Body (2) Liquid Effluents - Organ (3) Airborne Effluents - Tritium, lodines and Particulates (4) Noble Gases - Gamma (5) Noble Gases - Beta (6) Direct Radiation The doses for categories 1 and 2 were calculated using the methodology of the ODCM; these data are also presented in Table 2D. Categories 3, 4, and 5 were calculated utilizing RETDAS (Radioactive Effluent Tracking and Dose Assessment Software), Regulatory Guide 1.109 methodology, and concurrent meteorology. Table 1E of gaseous effluents previously presented, however, lists data similar to categories 3, 4 and 5 using methods described in the ODCM and the historical meteorology (X/Q). Category 6 presents direct dose data measured by TLD dosimeters. Each portion of each category is footnoted to briefly describe each maximum individual dose presented.

For members of the public, per the ODCM, who may at times be within the site boundary1 , the occupancy of the individual will be sufficiently low to compensate for any increase in the atmospheric diffusion factor above that for the site boundary. For members of the public who traverse the site boundary via highway 1-5, the residency time shall be considered negligible and hence the dose "0".

Table 2 in Section H presents the percent of Applicable Limits for each dose presented in Table 1.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT - 2010 SAN ONOFRE NUCLEAR GENERATING STATION SECTION I. CHANGES TO THE OFFSITE DOSE CALCULATION MANUAL On April 23, 2010, Revision 4 of the SONGS Offsite Dose Calculation Manual (ODCM) was adopted and published. This change incorporated changes due to the Safety Evaluation performed for Amendment No. 165 to Facility Operating License No. DPR-13, SONGS, Unit 1. This amendment changed the total dose calculation to consider the hypothetical contribution to public dose from the residual contamination in the Unit 1 conduit.

An effluent ODCM evaluation review was required and performed for the changes.

On March 17, 2011, Revision 5 of the SONGS Offsite Dose Calculation Manual (ODCM) was adopted and published. This change incorporated the following:

1. Incorporated the latest updates related to the 2010 Land Use Census (LUC) from the J.W. Scott to L. McCann Memorandum for File, "2011 Dose Parameters for San Onofre Units 2 and 3," dated January 27, 2011 and Memorandum for File, "2011 Dose Parameters for San Onofre Nuclear Generating Station South Yard Facility and North Industrial Area", dated February 8, 2011,
2. Deleted "type of samples and sampling location" in Table 5-4, per the Memorandum for File, "ODCM Table 5-4 revision recommendations", dated February 23, 2011.

An effluent ODCM evaluation review was required and performed for the changes.

None of the changes impacted the accuracy or reliability of effluent dose or setpoint calculations. The level of radioactive effluent control required by 10CFR20, 40CFR190, 10CFR50.35a and Appendix I to 10CFR50 will be maintained.

Throughout the document, change bars are marked in one of four ways as follows:

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT - 2010 SAN ONOFRE NUCLEAR GENERATING STATION SECTION K. MISCELLANEOUS ABNORMAL RELEASES

  • U3 High Conductivity Sump Overflow On 01/31/10 from 1010 to 1030, approximately 15 gallons of water from the Unit 3 High Conductivity Sump (HCS) overflowed and was released to the outfall via the storm drains. A valve clearance caused an unanticipated 250 gpm of water from the demineralized water header to flow to the HCS. Operator actions were taken as soon as the HCS level was observed to be near its high level overflow. The Unit 3 HCS sample contained 2.70E-6 microcuries/milliliter (uCi/ml) of tritium and no detectable gamma emitters. The dose commitment to a member of the public was conservatively calculated to be 2.57E-1 3 mrem total body and to the organ as a result of this event. This event is documented in Notification 200773694.

0 U2/3 Oily Waste Line Leak The discharge line from the west oily waste sump pump had an aboveground leak from 10/4 to 10/9/2010 that resulted in an estimated 2700 gallons containing 6.87E-6 uCi/ml of tritium and no detectable gamma emitters to the paved surface. The water was subsequently released to the outfall via the storm drains which is not its designed discharge path. The water originated from the turbine plant sumps which are ODCM-credited release points and has been accounted for in Table 2A of this report.

There was no additional dose consequence to a member of the public as a result of this event. This event is documented in Notification 201147182.

0 U3 Main Feedwater Block Valve Berm Overflow From 12/16/10 0145 to 12/22/10 1415, heavy rainfall resulted in the overflow of the berm beneath the Unit 3 Main Feedwater Block valve. Approximately 624 gallons of water containing 3.99E-6 uCi/ml tritium and no detectable gamma emitters was released from the berm to the outfall via the Unit 3 storm drains. The dose commitment to a member of the public was conservatively calculated to be 3.22E-1 1 mrem to the total body and to the organ as a result of this event. This event is documented in Notification 201252276.

  • U3 Containment Purge Unplanned Monitored Release On 12/20/10 from 1051 to 1203, during testing of the containment purge valves by Maintenance, the unit 3 containment main purge fan was inadvertently started with the purge valves open or partially open.

The release was monitored by Unit 3 containment purge monitor with a maximum release activity of 5.3E-6 microcuries/cubic centimeter. The monitor would have terminated the release before exceeding the limits in 10 CFR 20. The release was evaluated and the associated curies and dose consequences are included in Table 1 of this report. This event is documented in Notification 201262746.

MISCELLANEOUS 40 CFR 190 REQUIREMENTS Table 1 below presents the annual site-wide doses and percent of ODCM Specification limits to members of the public. These values were calculated utilizing doses resulting from all effluent pathways and direct radiation. The different categories presented are: (1) Total Body, (2) Limiting Organ, and (3) Thyroid.

Dose Category Units Year

1. Total Body
a. Total Body Dose mrem 9.96E-1
b. Percent ODCM Specification Limit  % 3.98E+0
2. Limiting Organ
a. Organ Dose (GI-LLI) mrem 2.OOE-2
b. Percent ODCM Specification Limit  % 7.98E-2
3. Thyroid
a. Thyroid Dose mrem 1.69E-2
b. Percent ODCM Specification Limit  % 2.25E-2 ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT - 2010 SAN ONOFRE NUCLEAR GENERATING STATION SECTION L. SONGS CONCLUSIONS Gaseous releases totaled 2.08E+2 curies of which noble gases were 1.26E+2 curies, iodines were 6.33E-4 curies, particulates were 6.91 E-4 curies, and tritium was 8.24E+1 curies.

The radiation doses from gaseous releases were: (a) gamma air dose: 4.96E-2 mrad at the site boundary, (b) beta air dose: 8.38E-2 mrad at the site boundary, (c) organ dose: 2.12E-2 mrem at the highest receptor.

Airborne carbon-14 releases totaled 2.19E+1 curies. The radiation dose from carbon-14 was an organ dose of 7.77E-1 mrem at the highest receptor.

Liquid releases totaled 8.69E+2 curies of which particulates and iodines were 3.16E-2 curies, tritium was 8.69E+2 curies, and noble gases were 2.55E-1 curies.

The radiation doses from liquid releases were: (a) total body: 1.96E-3 mrem, (b) limiting organ: 4.56E-3 mrem.

Radioactive releases and resulting doses generated from SONGS were below the applicable limits for both gaseous and liquid effluents.

SONGS 2 and 3 made 29 radwaste shipments to EnergySolutions, UT, Duratek/EnergySolutions, TN, and DSSI/PermaFix, TN. The total volume of the 29 shipments was 4.08E+2 cubic meters containing 4.43E-1 curies of radioactivity.

There were no radwaste shipments from Unit 1.

Meteorological conditions during the year were typical for SONGS Meteorological dispersion was good 36% of the time, fair 39% of the time and poor 25% of the time.

The results of samples taken from on-site ground water wells in support of the industry Ground Water Protection Initiative are reported in Section K. An investigation is being performed in the area formerly occupied by Unit 1 to characterize low, but detectable levels of tritium that are well below all regulatory limits (Notification 201053677). No other licensed radioactive material has been detected in on-site ground water samples. Ground water beneath SONGS is not a source of drinking water.

The net result from the analysis of these effluent releases indicates that the operation of SONGS has met all the requirements of the applicable regulations that ensure adequate protection of the health of members of the public.

METEOROLOGY METEOROLOGY The meteorology of the San Onofre Nuclear Generating Station for each of the four quarters, 2010 is described in this section. Meteorological measurements have been made according to the guidance provided in NRC Regulatory Guide 1.23, "Onsite Meteorological Programs." A summary report of the meteorological measurements taken during each calendar quarter are presented in Table 4A as joint frequency distribution (JFD) of wind direction and wind speed by atmospheric stability class.

Hourly meteorological data for batch releases have been recorded for the periods of actual release.

These data are available, as well as the hourly data for the Annual Report, but have not been included in this report because of the bulk of data records.

Table 4A lists the joint frequency distribution for each quarter, 2010. Each page of Table 4A represents the data for the individual stability classes: A, B, C, D, E, F, and G. The last page of each section is the JFD for all the stability classes. The wind speeds have been measured at the 10-meter level, and the stability classes are defined by the temperature differential between the 10-meter and 40-meter levels.
