EXECUTIVE

SUMMARY

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT The Annual Radioactive Effluent Release Report describes the radiological effluent control program conducted at Surry Power Station during the 2015 calendar year. This document summarizes the quantities of radioactive liquid and gaseous effluents and solid waste released from 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 or gaseous effluent releases as classified according to the criteria in the Offsite Dose Calculation Manual. Based on the 2015 effluent release data, IOCFR50 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 3.43E-04 mrem, which is 5.72-03% of the 6 mrem dose limit. The critical organ doses due to liquid effluents, GI-LLI and Liver respectively, were 1.0SE-03 mrem and 2.96E-04 mrem. These doses are 5.40E-03% and 1.48E-03% of the respective 20 mrem dose limit.

     . 2. The air dose due to noble gases in gaseous effluents was 5.05E-05 mrad gamma, which is 2.53E-04% of the 20 mrad gamma dose limit, and l .33E-04 mrad beta, which is 3.33E-04% of the 40 mrad beta dose limit.

3. The critical organ dose from gaseous effluents due to I-131, I-133, H-3, and particulates with half-lives greater than 8 days is 1.0SE-01 mrem, which is 3.60E-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 were two changes made to VPAP-2103S, Offsite Dose Calculation Manual, during this reporting period. Attachment 3 provides the changes to VPAP-2103S. In accordance with the Nuclear Energy Institute (NEI) Industry Ground Water Protection Initiative, analysis results of ground water monitoring locations not included in the Radiological Environmental Monitoring Program (REMP), will be included in this report. Ground water monitoring well sample results are provided in Attachment 8. 1

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. Purpose and Scope 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 2015. 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. If changes 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 and 6.3.2, a list and explanation for the inoperability of radioactive liquid and/or gaseous effluent monitoring instrumentation is provided in Attachment 5 of this report. Additionally, a list of unplanned releases during the reporting period is included in . provides the typical lower limit of detection (LLD) capabilities of the radioactive effluent analysis instrumentation. As required by the ODCM, Section 6.7.5, a summary of on-site radioactive spills or leaks that were communicated in accordance with the Industry Ground Water Protection Initiative reporting protocol, and sample analyses from ground water wells that are not part of the Radiological Environmental Monitoring Program are provided in Attachment 8. In 2015, no on-site radioactive spills or leaks were communicated in accordance with the Industry Ground Water Protection Initiative. 2

Discussion The basis for the calculation of the percent of technical specification for the critical organ in Table lA 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 receptor was the child for the first two quarters, the teen for the last two quarters; both via the inhalation pathway. The basis for the calculation of the percent of technical specification for the total body and skin in Table lA 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 Attachment 1 is the ODCM, Section 6.2.1, which states that the concentration of radioactive material released 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 2.00E-04 microcuries/mL. Percent of technical specification calculations are based on the total gaseous or liquid effluents released for the 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-131, iodine-133, tritium and all radionuclides in particulate form with half-lives greater than 8 days, was a child at 2.05 miles with the critical organ being the bone via the ingestion pathway. 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 typically being the 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. 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 maximurri 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 limit of detection, then the totals for this period will be designated as Not Applicable (NIA). 3

Supplemental Information Section 6.6.1 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. 4

Attachment 3 Page 1of1 REVISIONS TO OFFSITE DOSE CALCULATION MANUAL (ODCM) As required by Technical Specification 6.8.B, revisions to the ODCM, effective for the time period covered by this report, are included with this attachment. There were two general revision to the ODCM implemented during this reporting period. Revision 18:

Added substep 6.6.1.b.5 addressing deviations from the Radiological Environmental Monitoring Program (REMP) sampling schedule if specimens are unattainable and requiring all deviations to be documented in the annual REMP report.
Updated gaseous effluent dispersion and deposition factors.
Add a garden in the SSE sector for dose assessment. This garden was idenified as a new garden location in the 2014 Land Use Census.
Revised the description of Fish samples for the REMP to better represent the species available in the area for sampling.

Revision 19:

Resulting from a self assessment of the REMP, the following revisions were made:

Added, as Reference 3.1.28, the Branch Technical Position,, Revision 1, November 1979 Added a footnote to Attachment 8 to clarify that a TLD station does not exist in the 4 - 5 mile range of the SE sector due to geographical limitations. This area is over the water of the James River.

Resulting from corrective actions to Condition Report 1013104, documenting a liquid release without an operable flow rate measuring device, the following revisions were made:

Added, as Reference 3.1.29, CR1013104 On Attachment 1, revised the Action requirements for an unavailable flow rate measuring device to allow a liquid release with verification ofrelease rate at least once per 30 minutes using design capacity pump performance curves or volume released over time.

'*
Revised Substep 6.4.2.b to include the release of ground water wells as a contributor to the Continuous Release pathway.

DOMINION VPAP-2103S REVISION 18 PAGE40P76 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 monitoring 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 CPR 20, Appendix B, Table 2, Column 2, for radionuclides other than dissolved or entrained noble gases and 2E-4 µCi/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 CPR 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 mrem/yr to the skin
      .. I 131 , I 133 , 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 CPR 50, Appendix I, and
Exposure to areal individual will not exceed 40 CPR 190 dose limits 2.0 SCOPE This procedure applies to the Radioactive Effluent and Radiological Environmental Monitoring Programs at Surry Power Station.

It encompasses the entire channel, including the sensor and alarm and/or trip functions and the Channel Functional Test.

The Channel Calibration can be performed by any series of sequential, overlapping, or total channel steps so the entire channel is calibrated.

DOMINION VPAP-2103S REVISION 18 PAGE70F76 4.2 Channel Check A qualitative assessment, by observation, of channel behavior during operation. This assessment includes, where possible, comparison of the channel indication and/or status with other indications and/or status derived from independent instrumentation channels measuring the same parameter. The Channel Check for the MGPI sampler flow rate measuring devices, as listed on Attachment 6 of this procedure, is the direct observation of the MGPI radiation monitor release rate (i.e., microcuries per second) without the presence of a sampler flow fault display. 4.3 Channel Functional Test There are two types of Channel Functional Tests. 4.3.1 Analog Channel Injection of a simulated signal into a channel, as close to the sensor as practicable, to verify Operability, including alarm and/or trip functions. 4.3.2 Bistable Channel Injection of a simulated signal into a sensor to verify Operability, including alarm and/or trip functions. 4.4 Critical Organ That organ, which has been determined to be the maximum exposed organ based on an effluent pathway analysis, thereby ensuring the dose and dose rate limitations to any organ will not be exceeded. 4.5 Dose Equivalent 1-131 That concentration of I 131 (µCi/cc) that alone would produce the same thyroid dose as the quantity and isotopic mixture ofl 131 , I 132, I 133 , I 134, and I 135 actually present. Thyroid dose conversion factors for this calculation are listed in Table III of TID-14844, Calculation of Distance Factors for Power and Test Reactor Sites.

d. Bases - Liquid Effluent Concentration Limitations This control is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will not exceed 10 times the concentration values specified in Appendix B, Table 2, Column 2 of 10 CFR 20. The specific.ation provides operational flexibility for releasing liquid effluent in concentrations to follow the Section II.A and 11.C design objectives of Appendix I to 10 CFR Part 50. This limitation provides additional assurance that the levels ofradioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within: (1) the Section II.A design objectives of Appendix I, 10 CFR Part 50, to a MEMBER OF THE PUBLIC, and (2) restrictions authorized by 10 CFR 20.130l(e). The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its effluent concentration in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2. This specification does not affect the requirements to comply with the annual limitations of 10 CFR 20.130l(e).

a. Radioactive Liquid Effiuent Monitoring Instrumentation I Radioactive liquid effluent monitoring instrumentation channels shown on Radioactive Liquid Effluent Monitoring Instrumentation (Attachment 1) shall be operable with their alarm/trip setpoints set to ensure that Step 6.2. l .a. limits are not exceeded.

1. Alarm/trip setpoints of these channels shall be determined and adjusted in accordance with Step 6.2.2.d., Setpoint Calculation.

2. If a radioactive liquid effluent monitoring instrumentation channel alarm/trip setpoint is less conservative than required by Step 6.2.2.a., perform one of the following:

Promptly suspend release of radioactive liquid effluents monitored by the affected channel
Declare the channel inoperable
Change the setpoint to an acceptable, conservative value

b. Radioactive Liquid Effiuent Monitoring Instrumentation Operability Each radioactive liquid effluent monitoring instrumentation channel shall be demonstrated operable by performing a Channel Check, Source Check, Channel Calibration, and Channel Functional Test at the frequencies shown in Radioactive Liquid Effluent Monitoring Instrumentation Surveillance Requirements (Attachment 2).

1. If the number of operable channels is less than the minimum required by the tables in Radioactive Liquid Effluent Monitoring Instrumentation (Attachment

1) perform the action shown in those tables.

2. Attempt to return the instruments to operable status within 30 days. If unsuccessful, explain in the next Annual Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner.

d. Setpoint Calculation NOTE: This methodology does not preclude use of more conservative setpoints.

1. Maximum setpoint values shall be calculated by:

s (2) where: S = the setpoint, in µCi/mL, of the radioactivity monitor measuring the radioactivity concentration in the effluent line prior to dilution C = the effluent concentration limit for the monitor used to implement 10 CFR 20 for the Station (ACW in µCi/mL) for an isotopic mixture expected in the effluent FE = maximum design pathway effluent flow rate FD = dilution water flow rate calculated as: FE+ (200,000 gpm x number of circ. pumps in service)

2. Each of the condenser circulating water channels (e.g., SW-120, SW-220) monitors the effluent (service water, including component cooling service water, circulating water, and liquid radwaste) in the circulating water discharge tunnel beyond the last point of possible radioactive material addition. No dilution is assumed for this pathway. Therefore, Equation (2) becomes:

s =c (3) The setpoint for Station monitors used to implement 10 CFR 20 for the site becomes the effluent concentration limit.

DOMINION VPAP-2103S REVISION 18 PAGE 15 OF76

3. In addition, for added conservatism, setpoints shall be calculated for the service water system effluent line (i.e., SW-107 A, B, C, D), and the Radwaste Facility I effluent line (i.e., RRM-131).

4. For the service water system effluent line, Equation (2) becomes:

s (4) where: Ksw = Allocation fraction of the effluent concentration limit, used to implement 10 CFR 20 for the Station, attributable to the service water effluent line pathway

5. For the Radwaste Facility effluent line, Equation (2) becomes:

s (5) where: KRw = Allocation fraction of the effluent concentration limit, used to implement 10 CFR 20 attributable to the Radwaste Facility effluent line pathway

6. The sum Ksw + KRw shall not be greater than 1.0.

Less than or equal to 5 mrem to the critical organ

2. During any calendar year:

Less than or equal to 3 mrem to the total body
Less than or equal to 10 mrem to the critical organ

b. Action If the calculated dose from release of radioactive materials in liquid effluents exceeds any of the above limits, prepare and submit to the NRC, within 30 days, a special report in accordance with VPAP-2802, Notifications and Reports, that identifies causes for exceeding limits and defines corrective actions taken to reduce releases of radioactive materials in liquid effluents to ensure that subsequent releases will be in compliance with the above limits.

DOMINION VPAP-2103S REVISION 18 PAGE 17 OF76

c. Dose Contribution Calculations NOTE: All critical organ doses for each age group are calculated to determine which is the I limiting organ for the period being evaluated.

Dose contributions shall be calculated for all radionuclides identified in liquid effluents released to unrestricted areas based on the equation: D = tFM'°'C*A*L.i 1 1 (6) where: Subscripts = i, refers to individual radionuclide D = the cumulative dose commitment to the total body or critical organ from the liquid effluents for the period t, in mrem t = the period for which q and F are averaged for all liquid releases, in hours M = the mixing ratio (reciprocal of the dilution factor) at the point of exposure, dimensionless, 0.2 from Appendix l lA, Surry UFSAR F = the near field average dilution factor for Ci during any liquid effluent release; the ratio of the average undiluted liquid waste flow during release to the average flow from the site discharge structure to unrestricted areas Ci = the average concentration of radionuclide, i, in undiluted liquid effluent during the period t, from all liquid releases, in µCi/mL Ai = the site-related ingestion dose commitment factor to the total body or critical organ for a particular age group for each identified principal gamma and beta emitter in mrem/hr per µCi/mL (7)

d. Quarterly Composite Analyses For radionuclides not determined in each batch or weekly composite, dose contribution to current monthly or calendar quarter cumulative summation may be approximated by assuming an average monthly concentration based on previous monthly or quarterly composite analyses. However, for reporting purposes, calculated dose contribution shall be based on the actual composite, analyses.

e. Bases - Dose Due To Liquid Effluents This control is provided to implement the requirements of Sections II.A, ID.A, and I IV.A of Appendix I to 10 CFR Part 50. The control implements the guides set forth in Section II.A. The ACTION statement provides the required operating flexibility and at the same time implements the guides set forth in Section IV .A of Appendix I to assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable." The dose calculation methodology and parameters in the ODCM implement the requirements in Section III.A that conformance with the guides of Appendix I be shown by calculation procedures, such that the actual exposure of a MEMBER OF THE PUBLIC is unlikely to be substantially underestimated. The equations specified in the ODCM for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977.

6.2.4 Liquid Radwaste Treatment Historical data pertaining to the volumes and radioactivity of liquid effluents released in connection with specific station functions, such as maintenance or refueling outages, shall be used in projections as appropriate.

The Surry Radwaste Facility Liquid Waste System shall be used to reduce the radioactive materials in liquid waste prior to discharge when projected dose due to liquid effluent, from each reactor unit, to unrestricted areas would exceed 0.06 mrem to total body or 0.2 mrem to the critical organ in a 31-day period.

2. Doses due to liquid releases shall be projected at least once per 31 days.

DOMINION VPAP-2103S REVISION 18 PAGE200F76

b. Action If radioactive liquid waste is discharged without treatment and in excess of the above limits, prepare and submit to the NRC, within 30 days, a special report in accordance with VPAP-2802, Notifications and Reports, that includes the following:

1. An explanation of why liquid radwaste was being discharged without treatment, identification of any inoperable equipment or sub-system, and the reason for the inoperability.

2. Actions taken to restore inoperable equipment to operable status.

3. Summary description of actions taken to prevent recurrence.

c. Projected Total Body and Critical Organ Dose Calculation

1. Determine DL, the sum of all liquid open and closed release points, in mrem, by the ith organ, for the quarter.

2. Determine P, the Projection Factor, which is result of 31 divided by the number of days from start of the quarter to the end of the release.

3. Determine Da, additional anticipated dose for liquid releases by the ith organ for the particular quarter of the release.

4. Determine Dp, the 31 day projected dose by the ith organ:

Dp = (DL x P) + Da

d. Bases - Liquid Radwaste Treatment System The OPERABILITY of the Liquid Radwaste Treatment System ensures that this system will be available for use whenever liquid effluents require treatment prior to release to the environment. The requirement provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as is reasonably achievable." This control implements the requirements of 10 CPR 50.36a, General Design Criterion 60 of Appendix A to 10 CPR Part 50 and the design objective given in Section II.D of Appendix I to 10 CPR Part 50. The specified limits governing the use of appropriate portions of the Liquid Radwaste Treatment System were specified as a suitable fraction of the dose design objectives set forth in Section II.A of Appendix I, 10 CPR Part 50 for liquid effluents.

This specification is provided to ensure that gaseous effluents from all units on the site will be appropriately controlled. It provides operational flexibility for releasing gaseous effluents to satisfy the Section II.A and II.C design objectives of Appendix I to 10 CPR Part 50. The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a MEMBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrem/year to the whole body, less than or equal to 3000 mrem/year to the skin and the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrem/year. This specification does not affect the requirements to comply with the annual limitation of 10 CPR 20.1301(a). This control applies to the release of radioactive materials in gaseous effluents from all units at the site.

Suspend the release of radioactive gaseous effluents monitored by the affected channel and declare the channel inoperable or
Change the setpoint so it is acceptably conservative

2. If the number of operable channels is less than the minimum required by tables in Radioactive Gaseous Waste Sampling and Analysis Program (Attachment 4 ),

take the action shown in those tables.

3. Attempt to return instruments to operable status within 30 days. If unsuccessful, explain in the next Annual Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner.

DOMINION VPAP-2103S REVISION 18 PAGE 700F76 ATTACHMENT 12 (Page 1of7) 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 XIQ and D/Q values at critical locations around the Station for ventilation vent (ground level) and process vent (niixed mode) releases. The five year average XIQ and D/Q values are used in the dose pathway analysis to determine dose and dose rate at site boundary and dose to the member of the public. 1.2 MeteorolOgical Data, Parameters, and Methodology A five (5) year average ofrepresentative onsite meteorological data for the period January 1, 2007 through December 31, 2011, is used in the gaseous effluent dose pathway calculations. i This data includes wind speed, wind direction, and differential temperature for the purpose of I. determining joint frequency distributions for those releases characterized as ground level (i.e., ,- 1 ventilation vent), and those characterized as mixed mode (i.e., process vent). I 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 open terrain adjustment factors were applied to the XIQ 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 calculations included a building wake correction based on a 1516 m2 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 1.5 in. with plume exit velocity of 100 ft/sec.

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 1 lA-8. XIQ 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.

DOMINION VPAP-2103S REVISION 18 PAGE 71 OF76 ATTACHMENT 12 (Page 2of7) Meteorological, Liquid, and Gaseous Pathway Analysis 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-0133. 1.3 Results The XIQ and D/Q values used in the dose pathway analysis for ventilation vent releases and process vent releases can be found in Attachment 7. 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-1276. 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 hours per year, and that bank fishing would be performed a maximum of 160 hours per year.

DOMINION VPAP-2103S REVISION 18 PAGE 720F76 ATTACHMENT 12 (Page 3 of7) Meteorological, Liquid, and Gaseous Pathway Analysis 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, 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 Source Code file. Dose to an individual fishing on the discharge bank was 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, 1977, 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 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-LLI. The ingestion dose factors, which include the fish and invertebrate pathways, are calculated for total body and various critical organs. Validation of the limiting age group and critical organ is performed by the liquid effluent dose calculation program using the data, parameters, and methodology provided in the Source Code file. 3.0 GASEOUS PATHWAY ANALYSIS 3.1 Purpose Gaseous effluent pathway analyses are performed to determine the location that would result in the maximum doses due to noble gases, for use in demonstrating compliance with Steps 6.3.1.a. and 6.3.3.a. 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 I 131 , I 133 , tritium, and for all radionuclides in particulate form with half-lives greater than eight days for use in demonstrating compliance with Step 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 I 131 , I 133 , tritium, and particulates to demonstrate compliance with Step 6.3.l.a.

DOMINION VPAP-2103S REVISION 18 PAGE 73 OF76 ATTACHMENT 12 (Page 4 of7) Meteorological, Liquid, and Gaseous Pathway Analysis 3.2 Data, Parameters, and Methodology Five year average X/Q values were calculated, as described in Section 1 of this attachment. 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 the ventilation vent and process vent release points are summed to calculate total maximum dose. 6.3.l.a.2 dose limits apply specifically to the inhalation pathway. Therefore, the locations and XIQ values determined for maximum noble gas doses can be used to determine the maximum dose from I 131 , I 133 , tritium, and for all radionuclides in particulate form with half-lives greater than 8 days for the inhalation pathway. The maximum exposed individual for 10 CPR 50, Appendix I, compliance could be at any of the following locations: site boundary, nearest resident, nearest milk-cow, or nearest vegetable garden, using the Land Use Census data which is assessed annually. 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-0133 are used in the gaseous effluent dose pathway analyses. 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 Source Code file. Inhalation pathway dose factors Pivv and Pipv are calculated using the following equation: Pi= K' (BR) DFAi mrem/yr per Ci/m3 (28-1) where: K' = a constant of unit conversion, lE+ 12 pCi/Ci BR= the breathing rate of the particular age group, m 3/yr, from Table E-5, Regulatory Guide 1.109, Rev.1 DFAi = the critical organ inhalation dose factor for particular age group for the ith radionuclide, in mrem/pCi

It was determined that the member of the public within site boundary would be using the discharge canal bank for fishing a maximum of 160 hours per year. Active pathways are ground plane and inhalation, and all age groups are evaluated for this pathway analysis.

DOMINION VPAP-2103S REVISION 19 PAGE40F76 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 monitoring 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 µCi/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 mrem/yr to the skin
      ** 1131 , 1133 , and H3 , 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 Radiological Environmental

Monitoring Programs at Surry Power Station.

6.0 INSTRUCTIONS NOTE: Meteorological, liquid, and gaseous pathway analyses are presented in Meteorological, Liquid, and Gaseous Pathway Analysis (Attachment 12).

6.1 Sampling and Monitoring Criteria 6.1.1 Surveys, sampling, and analyses shall use instruments calibrated for the type and range of radiation monitored and the type of discharge monitored. 6.1.2 Installed monitoring systems shall be calibrated for the type and range of radiation or parameter monitored. 6.1.3 A sufficient number of survey points shall be used or samples taken to adequately assess the status of the discharge monitored. 6.1.4 Samples shall be representative of the volume and type of discharge monitored. 6.1.5 Surveys, sampling, analyses, and monitoring records shall be accurately and legibly documented, and sufficiently detailed that the meaning and intent of the records are clear. 6.1.6 Surveys, analyses, and monitoring records shall be reviewed for trends, completeness, and accuracy. 6.2 Liquid Radioactive Waste Effluents 6.2.1 Liquid Effluent Concentration Limitations

a. Liquid waste concentrations discharged from the Station shall not exceed the following limits:

1. For radionuclides (other than dissolved or entrained noble gases), liquid effluent concentrations released to unrestricted areas shall not exceed ten times the effluent concentration values specified in 10 CPR 20, Appendix B, Table 2, Column 2.

2. For dissolved or entrained noble gases, concentrations shall not exceed 2E-4 µCi/mL.

b. If the concentration of liquid effluent exceeds the limits in Step 6.2.1.a., promptly reduce concentrations to within limits.

DOMINION VPAP-2103S REVISION 19 PAGE 120F76

c. Concentrations of radioactive materials in liquid waste released to unrestricted areas shall meet the following:

Volume of Waste Discharged+ Volume of Dilution Water> (l) 1 Ci/mL. - Volume of Waste Discharged x ~ µ 1 Li ACW-1 where:

           µCi/mLi = the concentration of nuclide i in the liquid effluent discharge ACWi      =ten times the effluent concentration value in unrestricted areas of nuclide i, expressed as µCi/mL from 10 CFR 20, Appendix B, Table 2, Column 2 for radionuclides other than noble gases, and 2E-4 µCi/mL for dissolved or entrained noble gases

d. Bases - Liquid Effluent Concentration Limitations This control is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will not exceed 10 times the concentration values specified in Appendix B, Table 2, Column 2 of 10 CFR 20. The specification provides operational flexibility for releasing liquid effluent in concentrations. to follow the Section II.A and II.C design objectives of Appendix I to 10 CFR Part 50. This limitation provides additional assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within: (1) the Section II.A design objectives of Appendix I, 10 CFR Part 50, to a MEMBER OF THE PUBLIC, and (2) restrictions authorized by 10 CFR 20.1301(e). The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its effluent concentration in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2. This specification does not affect the requirements to comply with the annual limitations of 10 CFR 20.1301(e).

DOMINION VPAP-2103S REVISION 19 PAGE 13 OF76 6.2.2 Liquid Monitoring Instrumentation

a. Radioactive Liquid Effluent Monitoring Instrumentation Radioactive liquid effluent monitoring instrumentation channels shown on Radioactive Liquid Effluent Monitoring Instrumentation (Attachment 1) shall be operable with their alarm/trip setpoints set to ensure that Step 6.2.1.a. limits are not exceeded.

1. Alarm/trip setpoints of these channels shall be determined and adjusted in accordance with Step 6.2.2.d., Setpoint Calculation.

2. If a radioactive liquid effluent monitoring instrumentation channel alarm/trip setpoint is less coriser\rative than requrred by Step 6.2.2.a., perform one of the following:

Promptly suspend release of radioactive liquid effluents monitored by the affected channel
Declare the channel inoperable
Change the setpoint to an acceptable, conservative value

b. Radioactive Liquid Effiuent Monitoring Instrumentation Operability Each radioactive liquid effluent monitoring instrumentation channel shall be

' :i demonstrated operable by performing.a Channel Check, Source Check, Channel Calibration, and Channel Functional Test at the frequencies shown in Radioactive Liquid Effluent Monitoring Instrumentation Surveillance Requirements (Attachment 2).

1. If the number of operable channels is less than the. minimum required by the tables in Radioactive Liquid Effluent Monitoring Instrumentation (Attachment

1) perform the action shown in those tables.

2. Attempt to return the instruments to operable status within 30 days. If unsuccessful, explain in the next Annual Radioactive Effluent Release Report why the inoperability was not corrected in a timely manner.

c. Applicable Monitors Liquid effluent monitors for which alarm/trip setpoints shall be determined are:

Release Point Instrument Number Service Water System Effluent Line 1-SW-RM-107 A, B,C,D Condenser Circulating Water Line 1-SW-RM-120 2-SW-RM-220 Radwaste Facility Effluent Line RE-RRM-131

d. Setpoint Calculation NOTE: This methodology does not preclude use of more conservative setpoints.

1. Maximum setpoint values shall be calculated by:

s (2) where: S = the setpoint, in µCi/mL, of the radioactivity monitor measuring the radioactivity concentration in the effluent line prior to dilution C = the effluent concentration limit for the monitor used to implement 10 CFR 20 for the Station (ACW in µCi/mL) for an isotopic mixture expected in the effluent FE = maximum design pathway effluent flow rate FD = dilution water flow rate calculated as: FE+ (200,000 gpm x number of circ. pumps in service)

2. Each of the condenser circulating water channels (e.g., SW-120, SW-220) monitors the effluent (service water, including component cooling service water, circulating water, and liquid radwaste) in the circulating water discharge tunnel beyond the last point of possible radioactive material addition. No dilution is assumed for this pathway. Therefore, Equation (2) becomes:

s =c (3) The setpoint for Station monitors used to implement 10 CFR 20 for the site becomes the effluent concentration limit.

DOMINION VPAP-2103S REVISION 19 PAGE 15 OF76

3. In addition, for added conservatism, setpoints shall be calculated for the service water system effluent line (i.e., SW-107 A, B, C, D), and the Radwaste Facility effluent line (i.e., RRM-131).

4. For the service water system effluent line, Equation (2) becomes:

s (4) where: Ksw = Allocation fraction of the effluent concentration limit, used to implement 10 CFR 20 for the Station, attributable to the service water effluent line pathway

5. For the Radwaste Facility effluent line, Equation (2) becomes:

s (5) where:. KRw = Allocation fraction of the effluent concentration limit, used to implement 10 CFR 20 attributable to the Radwaste Facility effluent line pathway

6. The sum Ksw + KRw shall not be greater than 1.0.

        .e.

Less than or equal to 10 mrem to the critical organ

b. Action If the calculated dose from release of radioactive materials in liquid effluents exceeds any of the above limits, prepare and submit to the NRC, within 30 days, a special report in accordance with VPAP-2802, Notifications and Reports, that identifies causes for exceeding limits and defines corrective actions taken to reduce releases of radioactive materials in liquid effluents to ensure that subsequent releases will be in compliance with the above limits.

DOMINION VPAP-2103S REVISION 19 PAGE 17 OF76

c. Dose Contribution Calculations NOTE: All critical organ doses for each age group are calculated to determine which is the limiting organ for the period being evaluated.

Dose contributions shall be calculated for all radionuclides identified in liquid effluents released to unrestricted areas based on the equation: D = tFM'"'C*A* L.J 1 1 (6) where: Subscripts = i, refers to individual radionuclide D = the cumulative dose commitment to the total body or critical organ from the liquid effluents for the period t, in mrem t .- -* the period for which Ci and F are averaged for all liquid releases, in hours M = the mixing ratio (reciprocal of the dilution factor) at the point of exposure, dimensionless, 0.2 from Appendix 1 lA, Surry UFSAR F = the near field average dilution factor for Ci during any liquid effluent release; the ratio of the average undiluted liquid waste flow during release to the average flow from the site discharge structure to unrestricted areas Ci = the average concentration of radionuclide, i, in undiluted liquid effluent during the period t, from all liquid releases, in µCi/mL Ai = the site-related ingestion dose commitment factor to the total body or critical organ for a particular age group for each identified principal gamma and beta emitter in mrem/hr per µCi/mL (7)

d. Quarterly Composite Analyses For radionuclides not determined in each batch or weekly composite, dose contribution to current monthly or calendar quarter cumulative summation may be approximated by assuming an average monthly concentration based on previous monthly or quarterly composite analyses. However, for reporting purposes, calculated dose contribution shall be based on the actual composite analyses.

DOMINION VPAP-2103S REVISION 19 PAGE 19 OF76

e. Bases - Dose Due To Liquid Effiuents This control is provided to implement the requirements of Sections II.A, Ill.A, and IV.A of Appendix I to 10 CFR Part 50. The control implements the guides set forth in Section II.A. The ACTION statement provides the required operating flexibility and at the same time implements the guides set forth in Section IV .A of Appendix I to assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable." The dose calculation methodology and*parameters in the ODCM implement the requirements in Section Ill.A that conformance with the guides of Appendix I be shown by calculation procedures, such that the actual exposure of a MEMBER OF THE PUBLIC is unlikely to be substantially underestimated. The equations specified in the ODCM for calculating the doses due to the actual release rates of radioactive materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977.

The Surry Radwaste Facility Liquid Waste System shall be used to reduce the radioactive materials in liquid waste prior to discharge when projected dose due to liquid effluent, from each reactor unit, to unrestricted areas would exceed 0.06 mrem to total body or 0.2 mrem to the critical organ in a 31-day period.

2. Doses due to liquid releases shall be projected at least once per 31 days.

DOMINION VPAP-2103S REVISION 19 PAGE200F76

1. An explanation of why liquid radwaste was being discharged without treatment, identification of any inoperable equipment or sub-system, and the reason for the ino.:Perability.

2. Actions taken to restore inoperable equipment to operable status.

3. Summary description of actions taken to prevent recurrence.

c. Projected Total Body and Critical Organ Dose Calculation

1. Determine DL, the sum of all liquid open and closed release points, in mrem, by the ith organ, for the quarter.

2. Determine P, the Projection Factor, which is result of 31 divided by the number of days from start of the quarter to the end of the release.

3. Determine Da, additional anticipated dose for liquid releases by the ith organ for the particular quarter of the release.

4. Determine Dp, the 31 day projected dose by the ith organ:

Dp = (DL x P) + Da

d. Bases - Liquid Radwaste Treatment System The OPERABILITY of the Liquid Radwaste Treatment System ensures that this system will be available for use whenever liquid effluents require treatment prior to release to the environment. The requirement provides assurance that the releases of radioactive materials in liquid effluents will be kept "as low as is reasonably achievable." This control implements the requirements of 10 CFR 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section 11.D of Appendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the Liquid Radwaste Treatment System were specified as a suitable fraction of the dose design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50 for liquid effluents.

DOMINION VPAP-2103S REVISION 19 PAGE 700F76 ATTACHMENT 12 (Page 1of7) 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 XIQ and DIQ values at critical locations around the Station for ventilation vent (ground level) and process vent (mixed mode) releases. The five year average XIQ and D/Q values are used in the dose pathway analysis to determine dose and dose rate at site boundary and dose to the 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, 2007 through December 31, 2011, 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 releases characterized as ground level (i.e., ventilation vent), and those characterized as mixed mode (i.e., process vent). 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 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 calculations included a building wake correction based on a 1516 m2 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 1.5 in. with plume exit vefocity of 100 ft/sec. 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 l lA-8. XIQ 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 ventilatiOJ?- 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 1 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-0133. I 1.3

Results The XIQ and D/Q values used in the dose pathway analysis for ventilation vent releases and process vent releases can be found in Attachment 7.

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 iele~ses. 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-1276. 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 n.ot 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 hours per year, and that bank fishing would be performed a maximum of 160 hours per year.

DOMINION VPAP-2103S REVISION 19 PAGE 720F76 ATTACHMENT 12 (Page 3of7) Meteorological, Liquid, and Gaseous Pathway Analysis 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, 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 Source Code file. Dose to an individual fishing on the discharge bank was 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, 1977, 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 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-LLI. The ingestion dose factors, which include the fish and inyertebrate pathways, are calculated for total body and various critical organs. Validation of the limiting age group and critical organ is performed by the liquid effluent dose calculation program using the data, parameters, and methodology provided in the Source Code file. 3.0 GASEOUS PATHWAY ANALYSIS 3.1 Purpose Gaseous effluent pathway analyses are performed to determine the location that would result in the maximum doses due to noble gases, for use in demonstrating compliance with Steps 6.3.1.a. and 6.3.3.a. 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 rel~ase of I 131 , I 133 , tritium, and for all radionuclides in particulate form with half-lives greater than eight days for use in demonstrating compliance with Step 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 I 131 , I 133 , tritium, and particulates to demonstrate compliance with Step 6.3.1.a.

DOMINION VPAP-2103S REVISION 19 PAGE 73 OF76 ATTACHMENT 12 (Page 4 of7) Meteorological, Liquid, and Gaseous Pathway Analysis 3.2 Data, Parameters, and Methodology Five year average XIQ values were calculated, as described in Section 1 of this attachment. 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 the ventilation vent and process vent release points are summed 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 I 131 , I 133 , tritium, and for all radionuclides in particulate form with half-lives greater than 8 days for the inhalation pathway. The maximum exposed individual for 10 CFR 50, Appendix I, compliance could be at any of the following locations: site boundary, nearest resident, nearest milk-cow, or nearest vegetable

   *garden, using the Land Use Census data which is assessed annually. 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-0133 are used in the gaseous effluent dose pathway analyses. The gamma and beta dcise 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 Source Code file. Inhalation pathway dose factors Pivv and Pipv are calculated using the following equation: Pi= K' (BR) DFAi mrem/yr per Ci/m3 (28-1) where: K' =a constant of unit conversion, lE+ 12 pCi/Ci BR= the breathing rate of the particular age group, m 3/yr, from Table E-5, Regulatory Guide 1.109, Rev.l DFAi = the critical organ inhalation dose factor for particular age group for the ith radionuclide, in mrem/pCi

Attachment 5 Page 1of1 INOPERABILITY OF RADIOACTIVE LIQUID AND GASEOUS EFFLUENT MONITORING INSTRUMENTATION The Annual Radioactive Effluent Release Report shall explain why monitoring instrumentation required by the ODCM Attachments land 5, which were determined to be inoperable, were not returned to operable status within 30 days. Two of the above referenced instrumentation were inoperable greater than 30 days during this reporting period. On 05/06/2015, the Surry Radwaste Facility (SRF) Ventilation Stack Noble Gas Monitor selector switch was determined inoperable. The selector switch provides the capability to toggle through various monitor parameters and perform selected functions. Two instruments required to monitor the SRF stack release pathway, in accordance with Attachment 5 of the ODCM, were rendered inoperable with the loss of the selector switch. The instruments lost were the noble gas activity radiation monitor and the flow rate measuring device for the stack continuous particulate and iodine sampler. Additionally, although not required by Attachment 5, the capability to source check the noble gas activity radiation monitor was rendered inoperable. Compensatory measures for the loss of the instruments were initiated in accordance with the ODCM. For the loss of the noble gas activity radiation maonitor, grab samples of the SRF stack exhaust are taken and analyzed at least once every 12 hours. No activity has been detected in any of these samples. For the loss of the sampler flow rate measuring device, an estimate of the sampler flow rate is made at least once per 4 hours and documented in the Station logs. At this time, these instruments remain inoperable with compensatory measures in place. A similar radiation monitor skid was obtained to replace the current skid, but it could not be made functional.

EXECUTIVE

SUMMARY

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT The Annual Radioactive Effluent Release Report describes the radiological effluent control program conducted at Surry Power Station during the 2015 calendar year. This document summarizes the quantities of radioactive liquid and gaseous effluents and solid waste released from 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 or gaseous effluent releases as classified according to the criteria in the Offsite Dose Calculation Manual. Based on the 2015 effluent release data, IOCFR50 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 3.43E-04 mrem, which is 5.72-03% of the 6 mrem dose limit. The critical organ doses due to liquid effluents, GI-LLI and Liver respectively, were 1.0SE-03 mrem and 2.96E-04 mrem. These doses are 5.40E-03% and 1.48E-03% of the respective 20 mrem dose limit.

     . 2. The air dose due to noble gases in gaseous effluents was 5.05E-05 mrad gamma, which is 2.53E-04% of the 20 mrad gamma dose limit, and l .33E-04 mrad beta, which is 3.33E-04% of the 40 mrad beta dose limit.

3. The critical organ dose from gaseous effluents due to I-131, I-133, H-3, and particulates with half-lives greater than 8 days is 1.0SE-01 mrem, which is 3.60E-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 were two changes made to VPAP-2103S, Offsite Dose Calculation Manual, during this reporting period. Attachment 3 provides the changes to VPAP-2103S. In accordance with the Nuclear Energy Institute (NEI) Industry Ground Water Protection Initiative, analysis results of ground water monitoring locations not included in the Radiological Environmental Monitoring Program (REMP), will be included in this report. Ground water monitoring well sample results are provided in Attachment 8. 1

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. Purpose and Scope 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 2015. 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. If changes 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 and 6.3.2, a list and explanation for the inoperability of radioactive liquid and/or gaseous effluent monitoring instrumentation is provided in Attachment 5 of this report. Additionally, a list of unplanned releases during the reporting period is included in . provides the typical lower limit of detection (LLD) capabilities of the radioactive effluent analysis instrumentation. As required by the ODCM, Section 6.7.5, a summary of on-site radioactive spills or leaks that were communicated in accordance with the Industry Ground Water Protection Initiative reporting protocol, and sample analyses from ground water wells that are not part of the Radiological Environmental Monitoring Program are provided in Attachment 8. In 2015, no on-site radioactive spills or leaks were communicated in accordance with the Industry Ground Water Protection Initiative. 2

Discussion The basis for the calculation of the percent of technical specification for the critical organ in Table lA 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 receptor was the child for the first two quarters, the teen for the last two quarters; both via the inhalation pathway. The basis for the calculation of the percent of technical specification for the total body and skin in Table lA 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 Attachment 1 is the ODCM, Section 6.2.1, which states that the concentration of radioactive material released 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 2.00E-04 microcuries/mL. Percent of technical specification calculations are based on the total gaseous or liquid effluents released for the 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-131, iodine-133, tritium and all radionuclides in particulate form with half-lives greater than 8 days, was a child at 2.05 miles with the critical organ being the bone via the ingestion pathway. 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 typically being the 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. 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 maximurri 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 limit of detection, then the totals for this period will be designated as Not Applicable (NIA). 3

Supplemental Information Section 6.6.1 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. 4
