Ii\ ISOUTHERN CALIFORNIA EDISONS An EDISON INTERNATIOINALe Company 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 cn November 30, 1992. By August 31, 2004, all fuel was transferred to the Independent Spent Fuel Storage Installation (ISFSI). 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 ret megawatts electrical each. The twin units are owned by Southern California Edison (75.05%), San Diego Gas and Electric (20%), City of Anaheim (3.1.6%),

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (2005)

January - December 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 Generatinc Station, 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 (2005)

S.O.N.G.S. 1 SECTION B. GASEOUS EFFLUENTS Table IA, "Gaseous Effluents-Summation of All Releases," provides a detailed listing of gaseous. effluents released quarterly in four categories: fission and activation gases, iodine-131, 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 As of the fourth quarter of 2004, the noble gas and iodine source terms no longer exist, anc therefore are no longer measured. All the fuel is stored in the ISFSH and the plant is being demolished.

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 errcor 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 Unit 1 does not conduct elevated releases.

Table iC, "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 "continuous" mode of release.

Plant stack releases are considered to be "continuous" releases. As of 8/4/93, "batch" mode releases are no longer conducted because of the permanent shutdown of the reactor. As of the fourth quarter of 2004, the noble gas and iodine source terms no longer exist, and therefore are no longer measured. All the fuel is stored in the ISFSI and the plant is being demolished.

Table ID, "Gaseous Effluents-Lower Limit of Detection," provides a listing of lower limit of detection concentrations for radionuclides not detected in Tables 1A and IC for continuous mode releases only.

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

Table IF, "Gaseous Effluents-Batch Release Summary," has been deleted. "Batch" mode releases are no longer conducted as of 8/4/93, due to the permanent shutdown of the reactor.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (2005)

S.O.N.G.S. 1 SECTION C. LIQUID EFFLUENTS Table 2A, 'Liquid Effluents-Summation of All Releases," provides a detailed summary of liquid effluents released quarterly in three categories: fission and activation products, tritium, and dissolved and entrained gases. Listed for each of the three categories are:

(1) the total curies released (2) the average diluted concentration (3) the percent of applicable limit (4) the estimated total error In addition, Table 2A lists:

(1) the gross alpha radioactivity (2) the volume of waste released (prior to dilution)

(3) the volume of dilution water As of the fourth quarter of 2004, the noble gas and iodine source terms no longer exist, and therefore are no longer measured. All the fuel is stored in the ISFSI and the plant is being demolished.

The methodology used to calculate the percent of applicable limit is presented in Section F of this report. The methodology used to calculate the estimated total error in Table 2A is presented in Section G of this report.

Table 2B, "Liquid Effluents," provides the systematic listing by radionuclide for the quantity of radioactivity released in each category. The total radioactivity of each radionuclije released is listed for each quarterly period by both "continuous" and "batch" modes of release. As of the fourth quarter of 2004, the noble gas and icdine source terms no longer exist, and therefore are no longer measured. All the fuel is stored in the ISFSI and the plant is being demolished. As of the third quarter 2005 there are no longer batch releases being conducted due to the demolition of the liquid radwaste system.

Table 2C, "Liquid Effluents-Lower Limit of Detection," provides a listing of lower limit of detection concentrations for radionuclides not detected in Table 2B.

Table 2D, "Liquid Effluents-Radiation Doses at the Liquid Site Boundary," presents a quarterly summary of doses at the Liquid Site Boundary for this report period.

S.O.N.G.S. 1 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, Iodines 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 me:hods 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 boundary', 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 I-5, the residency time shall be considered negligible and hence the dose "0".

S.O.N.G.S. 1 SECTION I. CHANGES TO OFFSITE DOSE CALCULATION MANUAL On February 25, 2005, Revision 23 to the Unit 1 Offsite Dose Calculation Manual (OD)CM) was adopted and published. This revision incorporated 1) Removal of all the "notes" and applicable sections from rev 22 regarding the completion of fuel transfer to the ISFSI, 2) Addition of notes supporting the planned demolition of the liquid radwaste treatment system, 3) Updates related to the 2003-2004 Land Use Census, 4) Corrected dilution flowrate values, and 5) A minor change to a REMP sampling location.

A major milestone in the Unit 1 demolition plan, that of storing the last fuel cannister in the ISFSI, was accomplished in August 2004. Revision 22 was issued in advance to support that event. Several notes (dissolved/entrained gases and R-1254 setpoint) added in revision 22 were removed to reflect the completed event. The liquid radwaste treatment system (LRTS) was drained and isolated in 2005 and is currently being demolished. To support the demolition of the LRTS, notes were added in this revision to detail radwaste system specifications that are no longer applicable and instruments that are no longer required once systems were removed from service. Since the monitor was removed, requirements for surveillances and periodic maintenance were also removed. An EOE evaluation was performed for item 2.

The additic'nal dilution flow pumps added in revision 22 originally were believed to have a capacity of 6,000 gpm each. In reality, the pumps are designed at approximately 5,000 gpm.

Per NRC Generic Letter 89-01, no Effluent/ODCM Evaluation or 50.59 reviews wvere required or performed for editorial changes. The minor REMP sampling location change is administered by that program.

None of the changes impact the accuracy or reliability of the effluent dose or setpoint calculations. The level of radioactive effluent control required by 10CFR2O, 40CFR190, JOCFR50.36a, and Appendix I to 10CFR50 will be maintained.

S.O.N.G.S. 1 SECTION J. CHANGES TO RADIOACTIVE WASTE TREATMENT SYSTEMS Demolition of Liquid Radwaste Treatment System On May 13, 2005, the Liquid Radwaste Treatment System (LRTS) was permanently removed from service. The sump pumps, piping and radiation monitoring system skid (RE-1218) were removed to support the demolition of the radwaste building. Unit 1 has reached the point in its decommissioning where systems and buildings are being physically removed.

The LRTS was designed to collect drainage from primary side equipment leaks, the spent fuel pool and the RCS itself. It consisted of tanks, ion exchangers, filters and pumps used to process waste water to achieve 10CFR20 limits upon release. A radiation monitoring system was installed to satisfy the license and control releases from the system as an ODCM-credited release point.

Removal of the LRTS involved de-energizing the equipment related to the liquid radwaste processing system, placing a flange on the discharge pipe downstream of the pumps (eliminating the discharge line to the unrestricted area) and then removing a section of pipe. Later plans call for the removal of all components and piping as well as filling with concrete the outfall conduit east of the tsunami gates. The plan is to section this contaminated equipment and ship offsite to a licensed burial facility. As part of decommissioning, primary side systems were previously removed.

The containment building internals were removed and disposed of as dry active waste (DAW).

All of the piped sources of wastewater to the LRTS have been permanently drained of water and all sources have been either permanently drained and isolated or demolished to prevent any further water intrusion.

Once isolation of the LRTS was completed, approximately 26000 gallons of liquid waste were generated from draindown of the spent fuel pool, flushing of the ion exchangers, demineralizers, and spent resin tank, and cleanout of the holdup tanks. AR 060102024 details the disposal method and evaluation for this water.

However, after the LRTS was drained and released, there was residual water in various low points in the piping. The small quantities of liquid wastes will be dispositioned during dismantlement of the LRTS itself. This water is included in the estimate of 2000 gallons per quarter from decontamination activities and is expected to trend downwards as the demolition of the facility continues. This waste water will include residual water in the piping and tanks as well as water used in the washing and decontamination of system component parts.

The residual water has been and continues to be disposed of per the site program.

The various methods to be used to dispose of this residual water may include: 1) lease or purchase a processing skid to reduce the water contamination levels, 2) contract with an offsite vendor to use their treatment equipment to perform the same function, or 3) process it locally and then release through a credited release point to the Unit 2 or Unit 3 outfall. Release of Unit 1 water to the Unit 2 or Unit 3 outfall required a change to the operating license(s). AR 030300754 addresses the disposition of ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (2005)

S.O.N.G.S. 1 radioactive liquid wastes including wastes that would have been treated using the LRTS.

The only remaining credited liquid release point at Unit 1 is the Yard Drain Sump.

It is still receiving drains from the outside yard including rain runoff and dewatering from the demolition process.

This change was reviewed and approved acceptable pursuant to Quality Assurance Program Description (SCE-1-A), subsection 17.2.20.3.1.i per ECP 041100584.

  • Yard Drain Sump Overflow The Unit 1 Yard Drain sump overflowed to the PMF Catch Basin due to heavy rainfall on four different days in 2005. Since there was no detectable activity in the grab samples taken during the overflows, there were no dose consequences to a member of the public as a result of these unplanned, unmonitored releases. These events are documented in ARs 050100436, 050101565, 050401494 and 050600019.

  • Unknown Loss of Dilution Flow Durinq Liquid Releases Between 1/21/05 and 2/3/05, only one of two dilution pumps was providing actual dilution flow for three radwaste "C" Holdup Tank (CHUT) releases conducted during that time frame. The dilution pumps were both submerged in the intake structure with hoses attached directing dilution flow. On 2/3/05, unusual turbulence was observed on the water surface, which after investigation, revealed the disconnected hose. Operations ascertained the disconnect occurred on 1/21/05. The release permit setpoints were calculated using only one of the dilution pumps so all setpoints were valid and appropriately conservative. Post release doses were recalculated using the lower flow rates. The net reported dose impact to a member of the public was minimal with no dose limit reached. The actual dose to the public was controlled in the release by the valid setpoint. This event is documented in AR 050200268.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (2005)

S.O.N.G.S. 1 Unplanned Release of the Spent Fuel Pool Heat Exchanger Drains While reviewing Yard Drain Sump (YDS) weekly composite results for the week ending 4/18/05, a slightly higher than expected concentration of tritium was noted.

Investigation showed that the spent fuel pool heat exchanger (SFPHX) had been drained to the YDS earlier that week by mistake as the drains were directed to the incorrect yard drain. The plan had been to drain it to the auxiliary building sump and release it as radwaste. The release was monitored and sampled per procedure. The monitor setpoint was appropriately conservative. The dose impact to a member of the public was minimal as the maximum organ dose from this release (bone) was less than 10% of the total for the quarter; whole body was 6% of the quarter total. This event is documented in AR 050401027.

  • Incorrect Setpoint on Yard Drain Sump (YDS) Monitor R-2101 On 6/6/2005 Operations discovered that the incorrect setpoint was installed ir the YDS monitor, R-2101. On 6/3/2005 the north dilution pump was secured resultirg in only 2000 gpm dilution flow. The installed setpoint for R-2101 (based on 3000 gpm dilution and an administrative factor of 0.3), was non-conservative. However, given that the YDS was the only liquid release point in existence at that time, the entire administrative factor (1.0) for Unit 1 could have been allocated to the YDS. As such, a release could not have exceeded the limits of 10CFR20 even with the installed setpoint. Furthermore, the weekly gamma and tritium composite analyses for that time period were <LLD. There was no dose consequences to a member of the public, but if there had been any dose, it would have been included in Table 2D. This event is documentec in AR 050600267.
  • Sample Line Pump Leak on Plant Vent Stack (PVS) Monitor R-1254 On 10/11/05, a skid pump on the R-1254 sample line was found to be leaking during the channel calibration test. Since this leakage was downstream of the sample media, the result was a reduced volume from the plant vent stack being collected. The pump assembly %as replaced and the monitor returned to service on 10/14/05. The previous successfully conducted leak check was on 7/15/05 marking that point as the earliest failure date. Leak testing revealed that the inleakage was less than 50%. Note that since all of the spent fuel has been transferred to the ISFSI (fourth quarter 2004),

the requirement for a noble gas monitor is not applicable. Evaluation using 50% of the indicated sample flow revealed that all required LLD levels were met. All samples taken during that time period were <MDA. Therefore there were no dose consequences to a member of the public from this event which is documented in AR 051100265.

S.O.N.G.S. 2 and 3 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 a2 + G2 + CF + ... r2 where: a = Error associated with each component.

S.O.N.G.S. 2 and 3 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) Licuid Effluents - Whole Body (2) Licuid 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 me:hods 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 boundary', 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 I-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.

S.O.N.G.S. 2 and 3 SECTION I. CHANGES TO THE OFFSITE DOSE CALCULATION MANUAL On February 25, 2005, Revision 40 to the Units 2/3 Offsite Dose Calculation Manual (ODCM) was adopted and published. This change incorporated 1) Removal of the requirements for *a particulate activity radiation monitor from the South Yard Facility, 2) Updates related to the 2003-2004 Land Use Census (LUC), 3) A minor change to a REMP sampling location and 4) Various administrative changes.

An approved Effluent/ODCM Evaluation (EOE) was generated for item 1. Per NRC Generic Letter 89-01, no 50.59 or EOE reviews were required or performed for editorial changes made to reflect actual plant operation. The minor REMP sampling location change is administered by that program.

None of the changes impact 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.

METEOROLOGY METEOROLOGY The meteorology of the San Onofre Nuclear Generating Station for each of the four quarters, ;2005 is described in this section. Meteorological measurements have been made according to the guidance provided in USNRC 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, 2005. 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.
