EXECUTIVE

SUMMARY

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT The Annual Radioactive Effluent Release Report describes the radiological effluent control program conducted at the Surry Power Station during the 2001 calendar year.

This document summarizes the quantities of radioactive liquid and gaseous effluents and solid waste released from the Surry Power Station in accordance with Regulatory Guide 1.21, "Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants", Revision 1, June 1974. The report also includes an assessment of radiation doses to the maximum exposed member of the public due to the radioactive liquid and gaseous effluents.

During this reporting period, there were no unplanned liquid effluent releases and one unplanned gaseous effluent release as classified according to the criteria in the Offsite Dose Calculation Manual.

Based on the 2001 effluent release data, 10CFR50 Appendix I dose calculations were performed in accordance with the Offsite Dose Calculation Manual. The dose calculations are as follows:

1. The total body dose due to liquid effluents was 2.68E-04 mrem, which is 4.47E-03% of the 6 mrem dose limit. The critical organ doses due to liquid effluents, GI-LLI and Thyroid respectively, were 5.97E-04 mrem and 1.85E-04 mrem. These doses are 2.98E-03% and 9.25E-04% of the respective 20 mrem dose limit.

2. The air dose due to noble gases in gaseous effluents was 5.25E-04 mrad gamma, which is 2.62E-03% of the 20 mrad gamma dose limit, and 1.32E-03 mrad beta, which is 3.30E-03% of the 40 mrad beta dose limit.

3. The critical organ dose from gaseous effluents due to 1-131, 1-133, H-3, and particulates with half-lives greater than 8 days is 7.77E-02 mrem, which is 2.59E-01% of the 30 mrem dose limit.

There were no major changes to the radioactive liquid, gaseous or solid waste treatment systems during this reporting period.

There was one change to VPAP-2103S, Offsite Dose Calculation Manual, during this reporting period. Attachment 3 provides the changes to VPAP-2103S.

Based on the radioactivity measured and the dose calculations performed during this reporting period, the operation of Surry Power Station has resulted in negligible radiation dose consequences to the maximum exposed member of the public in unrestricted areas.

1

Purpose and Scope The Annual Radioactive Effluent Release Report, Attachment 1, includes a summary of the quantities of radioactive liquid and gaseous effluents and solid waste as outlined in Regulatory Guide 1.21, with data summarized on a quarterly or annual basis following the format of Tables 1, 2 and 3 of Appendix B thereof. Attachment 2 of this report includes an assessment of radiation doses to the maximum exposed member of the public due to radioactive liquid and gaseous effluents released from the site during the previous calendar year. Additionally, a list of unplanned releases during the reporting period is included in Attachment 6.

As required by Technical Specification 6.8.B, changes to the Offsite Dose Calculation Manual (ODCM) for the time period covered by this report are included in Attachment 3.

Major changes to the radioactive liquid, gaseous and solid waste treatment systems are reported in Attachment 4, as required by the ODCM, Section 6.7.2. Ifchanges are made to these systems, the report shall include information to support the reason for the change and a summary of the 10CFR50.59 evaluation. In lieu of reporting major changes in this report, major changes to the radioactive waste treatment systems may be submitted as part of the annual FSAR update.

As required by the ODCM, Sections 6.2.2.b.2 and 6.3.2.b.3, a list and explanation for the inoperability of radioactive liquid and/or gaseous effluent monitoring instrumentation is provided in Attachment 5 of this report.

Discussion The basis for the calculation of the percent of technical specification for the critical organ in Table 1A of Attachment 1 is the ODCM section, 6.3.1, which requires that the dose rate for iodine - 131, iodine - 133, for tritium, and for all radionuclides in particulate form with half-lives greater than 8 days shall be less than or equal to 1500 mRem/yr to the critical organ at or beyond the site boundary. The critical organ is the teen's thyroid, inhalation pathway.

The basis for the calculation of the percent of technical specification for the total body and skin in Table 1A of Attachment 1, is the ODCM, section 6.3.1, which requires that the dose rate for noble gases to areas at or beyond site boundary shall be less than or equal to 500 mRem/yr to the total body and less than or equal to 3000 mRem/yr to the skin.

The basis for the calculation of the percent of technical specification in Table 2A of , is the ODCM, section 6.2.1, which states that the concentration of radioactive material releases in liquid effluents to unrestricted areas shall not exceed ten times the concentrations specified in 10CFR20, Appendix B, Table 2, Column 2 for radionuclides other than dissolved or entrained noble gases. For dissolved or entrained noble gases, the concentration shall be limited to 2.OOE-04 microcuries/mL.

Percent of technical specification calculations are based on the total gaseous or liquid effluents released for that respective quarter.

The annual and quarterly doses, as reported in Attachment 2, were calculated according to the methodology presented in the ODCM. The beta and gamma air doses due to noble gases released from the site were calculated at the site boundary. The maximum exposed member of the public from the release of airborne iodine-1 31, iodine-1 33, tritium and all radionuclides in particulate form with half-lives greater than 8 days, was a teen at the site boundary with the critical organ being the thyroid gland. The maximum exposed member of the public from radioactive materials in liquid effluents in unrestricted areas was an adult, exposed by either the invertebrate or fish pathway, with the critical organ being either the thyroid gland or gastrointestinal-lower large intestine. The total body dose was also determined for this individual.

Presented in Attachment 6 is a list of unplanned gaseous and liquid releases as required by the ODCM, Section 6.7.2.

3

The typical lower limit of detection (LLD) capabilities of the radioactive effluent analysis instrumentation are presented in Attachment 7. These LLD values are based upon conservative conditions (i.e., minimum sample volumes and maximum delay time prior to analysis). Actual LLD values may be lower. If a radioisotope was not detected when effluent samples were analyzed, then the activity of the radioisotope was reported as Not Detected (N/D) on Attachment 1 of this report. When all isotopes listed on Attachment 1 for a particular quarter and release mode are less than the lower level of detection, then the totals for this period will be designated as Not Applicable (N/A).

4

Supplemental Information Section 6.6.1.b.4 of the ODCM requires the identification of the cause(s) for the unavailability of milk, or if required, leafy vegetation samples, and the identification for obtaining replacement samples. As milk was available for collection during this reporting period, leafy vegetation sampling was not required.

As required by the ODCM, Section 6.6.2, evaluation of the Land Use Census is made to determine if new sample location(s) must be added to the Radiological Environmental Monitoring Program. Evaluation of the Land Use Census conducted for this reporting period identified no change in sample locations for the radiological environmental monitoring program.

DOMINION VPAP-2103S REVISION 4 PAGE 5 OF 72 1.0 PURPOSE The Offsite Dose Calculation Manual (ODCM) establishes requirements for the Radioactive Effluent and Radiological Environmental Monitoring Programs. Methodology and parameters are provided to calculate offsite doses resulting from radioactive gaseous and liquid effluents, to calculate gaseous and liquid effluent moni~toring alarm/trip setpoints, and to conduct the Environmental Monitoring Program. Requirements are established for the Annual Radiological Environmental Operating Report and the Annual Radioactive Effluent Release Report required by Station Technical Specifications. Calculation of offsite doses due to radioactive liquid and gaseous effluents are performed to assure that:

" Concentration of radioactive liquid effluents to the unrestricted area will be limited to ten times the effluent concentration values of 10 CFR 20, Appendix B, Table 2, Column 2, for radionuclides other than dissolved or entrained noble gases and 2E-4 g.Ci/ml for dissolved or entrained noble gases.

"*Exposure to the maximum exposed member of the public in the unrestricted area from radioactive liquid effluents will not result in doses greater than the liquid dose limits of 10 CFR 50, Appendix I

"*Dose rate at and beyond the site boundary from radioactive gaseous effluents will be limited to:

Noble gases - less than or equal to a dose rate of 500 mrem/yr to the total body and less than or equal to a dose rate of 3000 mrern/yr to the skin 1131, 1133, and H 3 , and all radionuclides in particulate form with half-lives greater than 8 days - less than or equal to a dose rate of 1500 mrem/yr to any organ

"*Exposure from radioactive gaseous effluents to the maximum exposed member of the public in the unrestricted area will not result in doses greater than the gaseous dose limits of 10 CFR 50, Appendix I, and

"*Exposure to a real individual will not exceed 40 CFR 190 dose limits 2.0 SCOPE This procedure applies to the Radioactive Effluent and Environmental Monitoring Programs at Surry Power Station.

Meteorological, Liquid, and Gaseous Pathway Analysis 1.0 METEORLOGICAL ANALYSIS 1.1 Purpose The purpose of the meteorological analysis was to determine the five (5) year average X/Q and D/Q values at critical locations around the Station for ventilation vent (ground level) and process vent (mixed mode) .releases. The five year average V/Q and D/Q values are used in the dose pathway analysis to determine both the maximum exposed individual at site boundary and member of the public.

1.2 Meteorological Data, Parameters, and Methodology A five (5) year average of representative onsite meteorological data for the period January 1, 1992 through December 31, 1996, is Used in the gaseous effluent dose pathway calculations.

This data includes wind speed, wind direction, and differential temperature for the purpose of determining joint frequency distributions for those feleases characterized as ground level (i.e.,

ventilation vent), and those characterized as mixed mode (i.e., process vent). The portions of release characterized as ground level were based on AT 15 8 .9ft-28.2ft and 28.2 foot wind data, and the portions characterized as mixed mode werebased on AT1e8.9ft-28.2ft and 158.9 ft wind data.

X/Qs and D/Qs were calculated using the PC version of NRC computer code "XOQDOQ Program for the Meteorological Evaluation of Routine Effluent Releases at Nuclear Power Stations", Version 2.0, provided in NUREG-0324. The code is based upon a straight line airflow model implementing the assumptions outlined in Section C (excluding C Ia and C l b) of Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors."

The open terrain adjustment factors were applied to the X/Q values as recommended in Regulatory Guide 1.111. The site region is characterized as flat terrain such that open terrain correction factors are considered appropriate. The ground level ventilation vent release 2

calculations included a building wake correction based on a 1516 m containment minimum cross-sectional area. The effective release height used in mixed mode release calculations was based on a process vent release height of 131 ft, and plume rise due to momentum for a vent diameter of 3 in. with plume exit velocity of 100 ft/sec.

REVISION 4 PAGE 66 OF 72 ATTACHMENT 11 (Page 2 of 8)

Meteorological, Liquid, and Gaseous Pathway Analysis Ventilation vent, and vent releases other than from the process vent, are considered ground level as specified in Regulatory Guide 1.111 for release points less than the height of adjacent solid structures. Terrain elevations were obtained from Surry Power Station Units 1 and 2 Virginia Electric and Power Company Updated Final Safety Analysis Report Table 11A-8. I X/Q and D/Q values were calculated for the nearest site boundary, residence, milk-cow, discharge bank, and vegetable garden by sector for process vent and ventilation vent releases.

According to the definition for short term in NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Stations," October, 1978, some gaseous releases may fit this category, primarily waste gas decay tank releases and containment purges.

However, these releases are considered long term for dose calculations as past releases were both random in time of day and duration as evidenced by reviewing past release reports.

Therefore, the use of annual average concentrations is appropriate according to NUREG-0 133.

1.3 Results The X/Q value that would result in the maximum total body, skin, and inhalation exposure for ventilation vent releases was 6.OE-05 sec/m 3 at a site boundary location 532 meters NNE {

sector. For process vent releases, the site boundary ,/Q value was 3.7E-07 sec/m 3 at a location 565 meters WSW sector. The discharge canal bank XIQ value that would result in the maximum inhalation exposure for ventilation vent releases was 1.6E-04 sec/m 3 at a location 290 meters NW sector. The discharge canal bank X/Q value for process vent was 6.9E-07 sec/m 3 at a location 290 meters NW sector.

The D/Q value from ventilation vent releases that would result in the maximum exposure was 2.5E-10 per m2 at a location 5873 meters NNW sector. For process vent releases, the D/Q value was 1.4E-10 per m2 at a location 7788 meters SSW sector. For tritium, the X/Q value from ventilation vent releases that would result in the maximum exposure for the grass-cow-milk pathway 3

was 1.5E-06 sec/m 3 at a locations 5873 meters NNW sector, and 7.OE-08 sec/m for process vent releases at a location 7788meters SSW sector. The inhalation pathway is the only other pathway existing at this location. Therefore, the X/Q values given for tritium also apply for the inhalation pathway.

2.0 LIQUID PATHWAY ANALYSIS 2.1 Purpose The purpose of the liquid pathway analysis was to determine the maximum exposed member of the public in unrestricted areas as a result of radioactive liquid effluent releases. The analysis included a determination of most restrictive liquid pathway, most restrictive age group, and critical organ. This analysis is required for Subsection 6.2, Liquid Radioactive Waste Effluents.

2.2 Data, Parameters, and Methodology Radioactive liquid effluent release data for the years 1976, 1977, 1978, 1979, 1980, and 1981 were compiled from the Surry Power Station effluent release reports. The data for each year, along with appropriate site specific parameters and default selected parameters, were entered into the NRC computer code LADTAP as described in NUREG-0133.

Meteorological, Liquid, and Gaseous Pathway Analysis L Liquid radioactive effluents from both units are released to the James River via the discharge canal. Possible pathways of exposure for release from the Station include ingestion of fish and invertebrates and shoreline activities. The irrigated food pathway and potable water pathway do not exist at this location. Access to the discharge canal by the general public is gained two ways: bank fishing, controlled by the Station and limited to Dominion employees or guests of employees, and by boat as far upstream as the inshore end of the discharge canal groin. It has been estimated that boat sport fishing would be performed a maximum of 800 - I hours per year, and that bank fishing would be performed a maximum of 160 hours0.00185 days <br />0.0444 hours <br />2.645503e-4 weeks <br />6.088e-5 months <br /> per year.

For an individual fishing in the discharge canal, no river dilution was assumed for the fish pathway. For an individual located beyond the discharge canal groins, a river dilution factor of 5 (i.e. a mixing ratio of 0.2) was assumed as appropriate according to Regulatory Guide 1.109, I Rev. 1, and the fish, invertebrate, and shoreline pathways were considered to exist. Dose factors, bioaccumulation factors, shore width factors and usage terms for shoreline activities //

and ingestion of fish and invertebrates are included in the Canberra Source Code file. Dose to an individual fishing on the discharge bank wa-s determined by multiplying the annual dose calculated with LADTAP by the fractional year the individual spent fishing in the canal.

2.3 Results For the years 1976, i9771 1979, 1980, and 1981, the invertebrate pathway resulted in the largest dose. In 1978 the fish pathway resulted in the largest dose. The maximum exposed member of 4 the public was determined to utilize the James River. The critical age group was the adult and the critical organ was either the thyroid or GI-LII. The ingestion dose factors, which include the fish and invertebrate pathways, are calculated for total body and various critical organs.

l Validation of the limiting age group and critical organ is performed by Canberra's liquid effluent dose calculation program using the data, parameters, and methodology provided in the Canberra Source Code file.

The analyses includes a determination of the location, pathway, and critical organ, of the maximum exposed member of the public, as a result of the release of 1131, 1133, tritium, and for all radionuclides in particulate form with half-lives greater than eight days for use in demonstrating compliance with 6.3.4.a. In addition, the analyses includes a determination of the critical organ, maximum age group, and sector location of an exposed individual through the inhalation pathway from 1131, 1133, tritium, and particulates to demonstrate compliance with 6.3.1.a.

3.2 Data, Parameters, and Methodology Five year average XIQ values were calculated, as described in Section 1 of this attachment, for the nearest site boundary in each directional sector and at other Critical locations accessible to to be 6.0E-05 sec/m3 the public inside site boundary. The largest X/Q value was determined at site boundary for ventilation vent releases at a location 532 meters NNE direction, and 3.7E-07 sec/m 3 at site boundary for process vent releases at a location 565 meters WSW direction. The maximum doses to total body and skin, and air doses for gamma and beta radiation due to noble gases would be at these site boundary locations. The doses from both release points are summed in calculations to calculate total maximum dose.

6.3.l.a.2 dose limits apply specifically to the inhalation pathway. Therefore, the locations and X/Q values determined for maximum noble gas doses can be used to determine the maximum dose from 131, 1133, tritium, and for all radionuclides in particulate form with half-lives greater than 8 days for the inhalation pathway.

Meteorological, Liquid, and Gaseous Pathway Analysis The maximum exposed individual for 10CFR50 Appendix I compliance could be at any of the following locations: site boundary, nearest resident, nearest milk-cow, or nearest vegetable garden, using the 1996 Land Use Census data. Therefore, ventilation vent and process vent X/Q and D/Q values for these selected receptors are included in the gaseous effluent dose pathway analyses. Ground plane, inhalation, cow-milk, and vegetable garden pathways are active with the exception of the infant age group, which is not active for the vegetable garden pathway. Otherwise, all age groups are evaluated at these locations. The data, parameters, and {

methodology of R. G. 1.109, Rev. 1, and NUREG-0 133 are used in the gaseous effluent dose pathway analyses. I The gamma and beta dose factors Kivv, Livv, Mivv, and Nivv for ground level releases and the gamma and beta dose factors Kipv, Lipv, Mipv, and Nipv for mixed mode releases are included in the Canberra Source Code file.

Inhalation pathway dose factors Pivv and Pipv are calculated using the following equation: I Pi mrem/yr per Ci/m 3 = K' (BR) DFAi (28-1) where: I K' = a constant of unit conversion, 1E+12 pCi/Ci BR = the breathing rate of the particular age group, m3 /yr, from Table E-5, Regulatory Guide 1.109, Rev.1 I
