ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (1998)

S.O.N.G.S. 1 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 lB, "Gaseous Effluents-Elevated Release," has not been included in this report since San Onofre Nuclear Generating Station Unit 1 does not conduct elevated releases.

able 1C, "Gaseous Effluents-Ground Level Releases," provides the systematic listing radionuclide for the quantity of radioactivity released in three categories:

I* ssion 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 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 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 1F, "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.

S.0.N.G.S. 1 SECTION F. APPLICABLE LIMITS Gaseous Effluents - Applicable Limits The percent of Applicable Limits, tabulated in Sections A.3, B.3, C.3, and D.3 of Table 1A, was calculated using the following equation:

Applicable Limit = (Rel Rate) (X/Q) (100)

MPCeff where: Rel Rate = total curies released in each category and each quarter, divided by the seconds in a quarter; the value in Sections A.2, B.2, C.2 and D.2 of Table lA, MCi/sec.

X/Q = 1.30E-5 sec/m'; the annual average atmospheric dispersion defined in the Unit 1 ODCM, Rev. 13.

1 o MPCeff dn F

- MPC i where: F, = fractional abundance of the ith radionuclide obtained by dividing the activity (curies) for each radionuclide, C,,

S.O.N.G.S. 1 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

(3)sampling (2) 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:

2 2 2 2 Total Error =0 + + 3 + ... .

where: o= Error associated with each component.

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, 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, 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 individuals 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 atmospheri diffusion factor above that for the site boundary. For members of the public w traverse the site boundary via highway 1-5, the residency time shall be considerb negligible and hence the dose "O".

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

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 Generating Station, Units 2 and 3. 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

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 IB, "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.

ble 1C, "Gaseous Effluents-Ground Level Releases," provides the systematic listing 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 and monitor calibration 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 1F, "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.

S.O.N.G.S. 2 and 3 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 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 ntity of radioactivity released in each category. The total radioactivity of each ionuclide released is listed for each quarterly period by both "continuous" and "batch" modes of release.

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.

Table 2E, "Liquid 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.

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, 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 individuals who may, at times, be within the site boundary, the occupancy of the

'ndividual will be sufficiently low to compensate for any increase in the atmospheric ffusion factor above that for the site boundary. For members of the public who 4iaverse the site boundary via highway 1-5, the residency time shall be considered negligible and hence the dose "0".

SECTION J. CHANGES TO RADIOACTIVE WASTE TREATMENT SYSTEMS

There were no changes to the Units 2&3 Radioactive Waste Treatment Systems during the reporting period, January 1, 1998 to December 31, 1998.

SECTION K. MISCELLANEOUS

Improper Sampling of Unit 2 Turbine Plant Sump (TPS) System On 2/6/98, with the TPS radiation monitor, 2RT-7821, inoperable, a compensatory sample was obtained from the TPS discharge line compositor sample bottle instead of directly from the TPS. The ODCM requires a grab sample every 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months . The time between properly collected samples was 15 hours1.736111e-4 days 0.00417 hours 2.480159e-5 weeks 5.7075e-6 months and 40 minutes. Samples taken for several days before and after this incident were <MDA. This incident is documented in Action Request (AR) 980201214.

Missed Dilution Flow Surveillance A surveillance to determine the required operating dilution flow pumps once per 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months was missed. This surveillance was performed for batch releases but had not been proceduralized for continuous release pathways. Radiation monitor setpoints typically require less dilution than actually exists. This surveillance has been added to station procedures and a detailed M surveillance audit has been performed. This incident is documented in AR 980401703 and ensee Event Report (LER) 2-1998-006.

Non-isokinetic Sampling on Condenser Air Ejector Monitors During UFSAR Design Basis Document review, Condenser Air Ejector monitors, 2(3)RT-7870, particulate and iodine (P&I) samples were identified to be non-isokinetic at normal air ejector flow. A design error had made the samples isokinetic during vacuum pump operation only. New sample probe nozzles are scheduled to be installed during 1999 outages. In the interim, compensatory particulate and iodine samples are being obtained. Review of release data determined that there have been no significant dose consequences from airborne releases at SONGS 2 and 3. Noble gas radiation monitor functions are unaffected by this condition.

This incident is documented in ARs 980701509 and 980701514 AND LER 2-1998-015.

Non-isokinetic Sampling on Containment Purge Monitors During UFSAR Design Basis Document review, Containment Purge monitors, 2(3)RT-7865, P&I samples were identified to be non-isokinetic when selected to main purge. These monitors (both 2RT-7865 and 3RT-7865) have only been used for containment main purge 4 times in the last eight years. Procedures and release permit software have been modified to prohibit the use of these monitors for containment main purge. Review of release data determined that there have been no significant dose consequences from airborne releases at SONGS 2 and 3.

Noble gas radiation monitor functions were unaffected by this condition. This incident is umented inARs 980701530 and 980701531 and LER 2-1998-015.

Missed Duplicate Sample Due to Monitor Inoperability (CSRA# C-98-0238-3)

On 9/20/98, a Clean Sump Release Authorization (CSRA) was generated to release the Unit 3 Full Flow Condensate Polishing Demineralizer Holdup Tank utilizing only one sample. Radiation monitor 3RT-7817 was inoperable, requiring duplicate samples to be obtained prior to release.

The sample obtained showed less than minimum detectable activity and therefore there was no dose impact. To prevent recurrence, new release permit software requires verification of duplicate samples. This incident is documented in AR 980901251.

Valve Not Fully Locked Shut On 8/9/98, during weekly surveillance, Steam Generator 2E-089 blowdown via the flash tank bypass line isolation valve (S21301MU619) was found closed, but the lock not fully shut. The lock appeared to be locked, however, when handled, the lock opened. The ODCM requires samples be taken unless this valve is verified locked shut once every 31 days. The last time this valve was operated was February 1998 and there were no indications that it had been opened since then. No volume was estimated to have been released and therefore no dose impact resulted. This incident is documented in AR 980800502.

Missed Sample Flow Verification on Auxiliary Sampling Equipment On 10/6/98, the particulate and iodine sample flow was not verified at the proper interval for the Unit 3 condenser air ejector (CAE). Upon further investigation, it was identified that compensatory sample flow verification had not been proceduralized for either the plao vent stack or CAE since initial plant operation. Site procedures have been modified include this requirement. This incident is documented in AR 981000410 and LER 1-1998-00 5.

Inadvertent Waste Gas Decay Tank Discharge to Atmosphere On 4/13/98, Waste Gas Decay Tank, T-085, inadvertantly discharged to the Unit 3 Containment due to an improper valve line up. Investigation determined the discharge began when a valve was operated while performing an LLRT. A containment purge was in progress with a monitor to ensure the release was less than site limits. A conservative duration and sample analysis were used to estimate the curies released and the resultant dose. This incident is documented in AR 980301204. Procedures were revised to utilize caution tags to prevent recurrence.

Late Transient Sample Collection Due to Plant Conditions On 9/21/98, a Unit 2 post-transient ODCM required particulate and iodine sample of containment purge was collected one hour late due to a conflict with outage activities. When the sample was due, a critical evolution was in progress and securing containment purge to allow sample collection could not be supported and delayed sample collection. This incid is documented in AR 980901460. To prevent recurrence, this sample requirement has been ad*

to the detailed outage activity list.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (1998)

COMMON COMMON 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 6.21E-1

b. Percent ODCM Specification Limit % 2.49E+O

2. Limiting Organ

a. Organ Dose (GI-LLI) mrem 2.93E-2

b. Percent ODCM Specification Limit 4 1.17E-1

.Thyroid

a. Thyroid Dose mrem 1.22E-2

b. Percent ODCM Specification Limit 4 1.62E-2 In addition to the dose calculated in the table above, there is the potential for incremental exposure to the public through disposal of certain solid materials at a facility outside the sphere of influence of airborne and liquid pathways. For example, Southern California Edison collects marine debris on the screens of the circulating water system and gathers dirt and sweepings during housekeeping activities. From time to time, extremely low levels of radioactivity have been detected in these wastes, placing their disposal outside NRC jurisdiction as described in 10 CFR 61. The Department of Health Services for the State of California has evaluated the potential impact to the public attributable to disposing of these materials at a municipal facility and concluded that the maximum exposure to individuals living or working at the facility is an acceptably small fraction of the designated safe limits.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT (1998)

COMMON COMMON CONCLUSIONS

Gaseous releases from S.O.N.G.S. 1, 2 and 3 totaled 4.54E+2 curies of which noble gases were 4.24E+2 curies, iodines were 1.22E-2 curies, particulates were 7.83E-5 curies, and tritium was 2.96E+1 curies.

Liquid releases form S.O.N.G.S. 1, 2 and 3 totaled 1.54E+3 curies of which particulates and iodines were 2.16E-1 curies, tritium was 1.54E+3 curies, and noble gases were 2.54E-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 2 radwaste shipments to Barnwell, SC and 3 shipments to Envirocare, UT. Total volume was 2.93E+1 cubic meters containing 1.02E+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 43% of the time and poor 27% of the time.

METEOROLOGY The meteorology of the San Onofre Nuclear Generating Station for each of the four quarters, 1998 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. This data is available, as well as the hourly data for the Annual Report, but has not been included in this report because of the bulk of data records.

Table 4A lists the joint frequency distribution for each quarter, 1997. 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.
