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. It 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 (75.05%), San Diego Gas and Electric (20%), City of Anaheim (3.16%),

and the City of Riverside (1.79%).

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (2001)

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 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 IB, "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.

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 1E, "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.

2. Dose calculations for Table 1 Airborne Effluents and Noble Gases of this report are performed using concurrent meteorological data. On 10/27/00, it was determined a conversion factor of 2 had incorrectly been applied to wind speeds collected from 07/27/98 to 12/31/99 subsequent to a hard drive failure. This event is documented in AR 001002318.

The dose data have been reprocessed for the years 1998 and 1999. In no case did the percent of the dose limit exceed 1%. The revised data are provided in the following tables.

S.O.N.G.S. 1 SECTION H. 10 CFR 50 APPENDIX I REQUIREMENTS Table I 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; this data is also presented in Table 2D. Categories 3, 4, and 5 were calculated utilizing RRRGS (Radioactive Release Report Generating System) 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 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 1-5, the residency time shall be considered negligible and hence the dose "0".

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (2001)

S.O.N.G.S. 2 and 3 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-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 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 Units 2 and 3 do 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 ID, "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 IF, "Gaseous Effluents-Batch Release Summary," provides summary information regarding batch releases conducted during this report period from San Onofre Nuclear Generating Station Units 2 and 3.

2. The following information was not included in the 2000 report.

SECTION K. MISCELLANEOUS (2000)

Non-isokinetic Particulate and Iodine Sampling on Condenser Air Eiector Monitors On 1/21/00, it was determined that the Unit 2 and Unit 3 Condenser Air Ejector (CAE) radiation monitoring systems' sample flow was outside the design range for isokinetic flow (11.3-18.7 scfm). The process flow was immediately adjusted to ensure sampling within the allowable range. Based on testing of the actual plant configuration and equipment, it was determined that isokinetic flow could actually be maintained between 7.0 scfm to 22.5 scfm. From 2/21/99 to 1/21/00, Unit 2 CAE monitor sample flow was outside the allowable range 30% of the time while Unit 3, from 5/6/99, was outside 80% of the time. For the entire year, no particulate and iodine sample showed any detectable activity. The noble gas monitor was in service for the entire time period.

This event is documented in AR 000101252.

0 Missed Process Flow Estimate On 5/2/00 the Unit 3 Full Flow Condensate Polishing Demineralizer Holdup Tank was released with the process flow instrument, 3FQ13772, out of service. The one hour flow check required by the ODCM under these conditions was missed. The flow estimate was completed at 66 minutes. There were no dose consequences to the public as a result of this event that is documented in AR 000500145.

Loss of Heat Tracing on Plant Vent Stack Monitor (2RT-7865)

On 5/10/00, the heat tracing for the sample lines for 2RT-7865 was identified as inoperable due to a failed breaker. The last time the heat tracing had been verified operable was on 3/7/00 during a Channel Functional Test. During the period of 3/7/00 to 5/10/00, particulate and iodine samples from 2RT-7865 were only used for dose calculations from 3/15/00 to 3/29/00. Sample results of the weeks previous and following this time period, from different monitors, showed similar or lower iodine activity. There was no particulate activity during this time. There were no dose consequences to the public as a result of this event that is documented in AR 000400609.

3. Dose calculations for Table 1 Airborne Effluents and Noble Gases of this report are performed using concurrent meteorological data. On 10/27/00, it was determined a conversion factor of 2 had incorrectly been applied to wind speeds collected from 07/27/98 to 12/31/99 subsequent to a hard drive failure. This event is documented in AR 001002318.

On 12/7/01, it was determined the computer program used to perform airborne dose calculations did not have the current controlling location receptor parameters.

In August 1998, during system repair, the file was replaced but the contents were not verified prior to use. This event is documented in AR 010201705. The operating procedure has been revised to verify file data prior to use.

The dose data have been reprocessed for the years 1998, 1999 and 2000. In no case did the percent of the dose limit exceed 1%. The revised data are provided in the following tables.

(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:

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) 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 RRRGS (Radioactive Release Report Generating System) 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 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 1-5, the residency time shall be considered negligible and hence the dose "0".

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (2001)

S.O.N.G.S. 2 and 3 SECTION I. CHANGES TO THE OFFSITE DOSE CALCULATION MANUAL On February 28, 2001, Revision 36 to the Units 2/3 Offsite Dose Calculation Manual was adopted and published. This change incorporated the following:

1. Update to SYF flowrates,

2. Addition of liquid composite samplers to Section 4,

3. Change to 6.3.1.a to require ODCM updates be made in accordance with applicable regulations rather than IOCFR50.59, {due to changes in the 10CFR50.59 program}

4. Deleted the Investigative Report definition, and

5. Changes related to the Land Use Census update.

Safety Evaluations were provided for items 2 and 3. The requirement for an Investigative Report was added to the ODCM at the time that the RETS were transferred from the Technical Specifications. There existed a need to document each occurrence of failure to meet Surveillance Requirements and/or Action Statements related to the ODCM. The ODCM will now require performance of an evaluation based on the significance of the event in accordance with the site Corrective Action Program.

Per NRC Generic Letter 89-01, no safety reviews were required or performed for editorial changes or changes made to reflect actual plant operation.

Minor format changes, correction of typographical errors, and removal of previously blank pages have been made and are described in the attached List of Affected Pages.

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, 10CFR50.36a, and Appendix I to IOCFR50 will be maintained.

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

SECTION K. MISCELLANEOUS Leaking Unit 2 Steam Generator Blowdown Valves In December 2000, Unit 2 Steam Generators were estimated to be leaking past their blowdown isolation valves to the outfall at 1 gpm, with a maximum leak rate of 2 gpm. Compensatory sampling was performed all year (samples indicated no detectable gamma activity for the year with trace amount of tritium). Valve repair is planned for the outage in 2002. A recent engineering evaluation has determined there is minimal leakage, less than can be accurately measured (less than 1 gpm). This event is documented in AR 001200733.

SUBJECT:

Process Control Program (PCP) Procedure Revision Health Physics is issuing a comprehensive revision of S0123-VII-8.5.1, Process Control Program. The purpose of this memorandum is to inform you, as required by procedure, of changes made to the PCP and their bases.

Revision 7 of the PCP procedure contains changes that are only administrative in nature. Changes principally include:

1. A restatement of the procedure objective to more concisely link general objectives to specific references.

2. Updated and expanded references, including the Unit 1 DSAR.

3. Reorganized and restated procedure steps to more clearly link requirements to referenceg.

4. Revised statements of administrative controls that quote, rather than paraphrase, requirements imposed by the TQAM, LCSs, etc.

5. Deletion of record requirements duplicated in other Health Physics procedures and not required to meet PCP objectives.

The changes made to the PCP procedure are justified as administrative in nature. The core PCP objective, ensuring all solid radioactive waste processing conform to form, stability, and free-standing water requirements, remains intact.

With the core requirements of the procedure unchanged, overall conformance of SONGS solid radioactive waste products with applicable requirements is maintained.

Implementing procedures, such as those controlling the actual processing and packaging of radioactive wastes, are unaffected.

Please contact me if I can be of assistance.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (2001)

COMMON COMMON CONCLUSIONS Gaseous releases from S.O.N.G.S. 1, 2 and 3 totaled 1.71E+2 curies of which noble gases were 8.68E+1 curies, iodines were 4.56E-2 curies, particulates were 2.OOE-3 curies, and tritium was 8.36E+1 curies.

Liquid releases form S.O.N.G.S. 1, 2 and 3 totaled 9.61E+2 curies of which particulates and iodines were 1.95E-2 curies, tritium was 9.60E+2 curies, and noble gases were 5.98E-1 curies.

Radioactive releases and resulting doses generated from S.O.N.G.S. 1, 2 and 3 were below the Applicable Limits for both gaseous and liquid effluents.

S.O.N.G.S. 1, 2 and 3 made 134 radwaste shipments to Envirocare, UT. Total volume was 2.54E+3 cubic meters containing 1.32E+O curies of radioactivity.

Meteorological conditions during the year were typical for S.O.N.G.S.

Meteorological dispersion was good 30% of the time, fair 47% of the time and poor 23% of the time.

The net result from the analysis of these effluent releases indicates that the operation of S.O.N.G.S. 1, 2 and 3 has met all the requirements of the applicable regulations and therefore has not resulted in any detrimental effects to a member of the public.

For dissolved or entrained noble gases, the concentration is limited to 2.OOE-4 pCi/ml.

B. Table 2D lists doses due to liquid releases. The dose commitment to a Member of the Public from radioactive materials in liquid effluents released from S.O.N.G.S. (per reactor) to unrestricted areas shall be limited to the following values:

1. During any calendar quarter: < 1.5 mrem to the total body and

5 mrem to any organ.

2. During any calendar year: <3 mrem to the total body and

<10 mrem to any organ.

METEOROLOGY METEOROLOGY The meteorology of the San Onofre Nuclear Generating Station for each of the four quarters, 2001 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, 2001. 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.
