ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2016 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS Introduction This report is being submitted as a summary of quantities of radioactive liquid and gaseous effluents and solid waste released from the Virgil C. Summer Nuclear Station.

This report is submitted in fulfillment of the requirements in the Virgil C. Summer Nuclear Station Operating License Technical Specifications Section 6.9.1.8, Offsite Dose Calculation Manual (ODCM) Section1.6.2 and 10CFR50.36(a) and follows the reporting details specified in USNRC Regulatory guide 1.21(1).

Summary information of radioactive gaseous and liquid effluents is presented along with a summary of radioactive waste disposal as well as an evaluation of the radiological impact on man due to operation of the Virgil C. Summer Nuclear Station. Supplemental information including release limits also required by USNRC Regulatory Guide 1.21 is provided as Appendix A.

During the reporting period there was one revision made to the Offsite Dose Calculation Manual (ODCM) during the 12-month period. Details are presented below.

A. Supplemental Information Regulatory limits for doses, dose rate and effluent concentration limits presented in Supplemental Information are from the Virgil C. Summer Nuclear Station ODCM and 40 CFR 190. Average energy (E bar) is not applicable to the method for determining release rate limits for fission and activation gaseous effluents, therefore, it has been omitted. A compilation of required supplemental information is provided in Appendix A.

B. Gaseous Effluents Gaseous effluents released from ground level are summarized in Tables 1 and 2. An elevated release pathway does not exist at the Virgil C. Summer Nuclear Station. Cumulative doses are discussed in Section E.

The error for both liquid and gaseous release totals is estimated as twenty percent for radionuclides sampled and released in effluent pathways. Error was derived using root sum of squares methodology considering known sources of error including calibration of detectors and flow measurement equipment, sample preparation, and analysis counting error.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2016 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS C. Liquid Effluents Liquid effluents are summarized in Tables 3 and 4. Estimated total errors are expressed as in Section B above.

D. Solid Waste Shipments Solid waste shipments are summarized in Table 5. Curie content of radioactive waste packages is determined by dose rates and/or gamma spectroscopy analysis of samples. The total error for each type of curie content determination is conservatively estimated to be the sum of a 15%

systematic error and a 20% photon response error for the detector used.

E. Radiological Impact on Man Dose to the maximum exposed individual in the unrestricted area was calculated using measured plant gaseous effluents and meteorological data in accordance with the Offsite Dose Calculation Manual. The source term involved one abnormal Waste Gas Decay Tank (WGDT) release, 54 minutes of 6-inch Reactor Building purge releases, no 36-inch Reactor Building purge releases and a continuous 12-month Main Plant Vent release. Doses are summarized in Table 6. The total gaseous activities released are presented in Tables 1 and 2. The highest quarterly air doses at the station boundary resulting from the release of noble gases were 1.16E-05 mrad for gamma during the second quarter and 1.03E-05 mrad for beta during the second quarter. The maximum quarterly organ dose attributed to the releases, excluding Carbon-14, was 5.52E-06 mrem. Cumulative annual dose was 1.16E-05 mrad, 1.03E-05 mrad and 5.52E-06 mrem for gamma, beta, and organ dose, respectively. Discussion of the impact of Carbon-14 is included in Section K.

Measured plant liquid effluent data was used to calculate estimates of doses to individuals in accordance with the Offsite Dose Calculation Manual. The source term consisted of the radioisotope content of 138 Waste Monitor Tank batch releases, 1 Condensate Backwash Receiver Tank batch release, 4 NaOH Sump batch releases, 2.1 days of Steam Generator Blowdown release and a continuous Turbine Building Sump release.

Doses are summarized in Table 6 and total liquid radioactivity released is described in Tables 3 and 4. The highest quarterly total body dose to the maximum exposed individual resulting from the release of radioactive liquid

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2016 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS was 2.78E-03 mrem during the fourth quarter. The highest organ dose was 2.79E-03 mrem to the Liver for the fourth quarter. Cumulative annual doses for the hypothetical maximum exposed individual were 3.74E-03 mrem for the total body and 4.04E-03 mrem for the GI-LLI, the maximum annual organ. The GI-LLI was the maximum exposed organ for the first and second quarter and the Liver was the maximum exposed organ for the third and fourth quarter.

Dose rates and concentrations were below station limits as specified in Supplemental Information,Section II A, B, and C during all the effluent releases.

Radiation exposure to members of the public within the site boundary was assessed through calculation of gamma and beta air dose at 0.25 miles of the gaseous effluent release point and direct measurement of exposure using thermoluminescent dosimeters. Onsite air dose for this reporting period was 3.78E-05 mrad gamma and 3.35E-05 mrad beta, well below levels that can be distinguished above background. Quarterly thermoluminescent dosimetry (TLD) data from four onsite monitoring locations within 0.2 miles of the Reactor Building and eight locations at the site boundary were analyzed and compared with respective pre-operational background and previous year history. Results showed that the 2016 quarterly dose rates did not differ from the pre-operational or 2015 dose rates.

The impact of Independent Spent Fuel Storage Installation (ISFSI) operation which began cask storage on March 26, 2016 was assessed using six TLD locations monitoring the perimeter of the ISFSI site. The TLD locations were monitored for three quarters prior to fuel storage and the three quarters of 2016 during which fuel storage casks were stored. Analysis of monitoring results showed no statistically significant increase in perimeter dose as a result of ISFSI operation.

Based on review of gaseous effluent dose calculations and analysis of onsite TLD monitoring it was concluded that doses to members of the public inside the site boundary were indistinguishable from normal background dose.

Radiation doses from radioactive effluents to workers at the Fairfield Hydro Station for this reporting period were calculated to be 5.49E-07 and 4.87E-07 mrad for gamma and beta, respectively.

Radiation doses from radioactive effluents to workers at the New

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2016 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS Nuclear Site for this reporting period were calculated to be 4.72E-06 and 4.19E-06 mrad for gamma and beta, respectively.

Radiation doses from nearby uranium fuel cycle sources were not assessed. The ODCM, Sections 1.3.1 and B/1.3 establish a five (5) mile limit beyond which doses from nearby plants are insignificant.

There are no uranium fuel cycle plants within a five (5) mile radius of the Virgil C. Summer Nuclear Station.

F. Abnormal Releases Between May 23, 2016 at 2300 and May 24, 2016 at 0130, pressure dropped unexpectedly from approximately 7.5 psig to 0.3 psig on Waste Gas Decay Tank B(WGDT B). The Waste Gas System was shutdown to investigate and repair the leak. The contents of the tank were suspected to have slowly leaked out of the system into the Auxiliary Building. Radiation monitors showed no increase in the Auxiliary Building or the Main Plant Vent.

The content of WGDT B at a pressure of 11.8 psig was last sampled on May 13th at 0935. To be conservative, a permit and dose calculation were generated using the May 13th tank analysis. The calculated total activity released for the period was 2.53E-02 Curies. The dose rate to Total Body was 4.37E-02 mrem/yr equating to 0.09 % of the yearly limit .

G. Meteorology The meteorological data for 2016 was collected and analyzed. An annual meteorological summary report providing joint frequency distributions of wind direction and speed by atmospheric stability class is maintained in plant records.

The wind direction and wind speed data used were acquired from the 10-meter level of the primary monitoring tower. Stability was determined by the primary differential temperature (61 to 10 meter).

The combined annual data recovery for wind direction, wind speed and stability was 99.9%. Primary variable recovery rates were as follows: wind direction (10 m) - 99.9%, wind speed (10 m) - 99.9%, and differential temperature (61 - 10 m) - 99.9%.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2016 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS H. Offsite Dose Calculation Manual The Virgil C. Summer Nuclear Station ODCM was revised on March 8, 2016. See Enclosure A for a complete copy.

The revision was required to implement the Radiological Effluents Administration System (RADEAS) software which has replaced the VAX based Effluent Management System (EMS) and to address dry fuel storage monitoring requirements. Revision 30 includes a change in organ dose calculation methodology for gaseous radiological releases. To demonstrate compliance with ODCM Specification 1.2.4.1, the previous ODCM methodology used a maximum hypothetical organ concept in which the dose was summed from the maximum organ for each radioisotope. The revised methodology calculates dose for each individual organ for each isotope and then sums the doses for all individual organs. The highest organ dose is then selected for use in demonstrating compliance with ODCM Specification 1.2.4.1.

Setpoint methodology related to liquid effluent releases was revised to be consistent with the RADEAS setpoint algorithm. Effectively, the result is a more limiting permissible discharge flow rate calculation. Reference to dilution and discharge flow rate setpoints including dilution flow setpoint formulas were deleted. It was recognized in Revision 5 of the ODCM that there is no physical/electrical setpoints for discharge and dilution flowrates other than the penstock minimum flow interlock. The setpoint wording was removed for clarity.

ISFSI was added as a fuel cycle source and 6 TLD locations and their reporting requirements were also added.

I. Offsite Dose Calculation Manual Reportable Incidents There were no ODCM reportable incidents in 2016.

J. Major Changes to Radioactive Waste Treatment Systems During 2016, there were no major changes to the Radioactive Waste Treatment System.

ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT JANUARY - DECEMBER, 2016 VIRGIL C. SUMMER NUCLEAR STATION SOUTH CAROLINA ELECTRIC & GAS K. Carbon-14 Gaseous Effluents Carbon-14 production and release estimates were calculated using EPRI Report 1021106(2), Estimation of Carbon-14 in Nuclear Plant Gaseous Effluents. This calculation uses active core coolant mass, average neutron flux by energy and reactor coolant nitrogen concentrations to determine Carbon-14 generation based upon an effective full power year. The estimated generation for the Virgil C.

Summer Nuclear station for 2016 was 10.2 curies.

Public dose estimates were performed using Regulatory Guide 1.109 (3) methodology. Carbon dioxide is assumed to make up 20% of the Carbon-14 gaseous emissions from the station based upon available references and on-site testing. Carbon-14 is the highest dose contributor of all radionuclides released in gaseous effluents. Annual dose resulting from Carbon-14 releases in gaseous effluents is estimated to be 1.66E-01 mrem total body and 8.32E-01 mrem to the maximum organ (bone).

INTRODUCTION The OFFSITE DOSE CALCULATION MANUAL (ODCM) is an implementing and CO2 supporting document of the RADIOLOGICAL EFFLUENT TECHNICAL SPECIFICATIONS (RETS). In accordance with USNRC Generic Letter 89-01, entitled Implementation of Programmatic Controls for Radiological Effluent Technical Specifications in the Administrative Controls Section of the Technical Specifications and the Relocation of Procedural Details of RETS to the Offsite Dose Calculation Manual or to the Process Control Program, the procedural details for implementing the Radiological Controls have been incorporated into the ODCM. The ODCM describes the methodology and parameters to be used in the calculation of offsite doses due to radioactive liquid and gaseous effluents and in the calculation of liquid and gaseous effluent monitoring instrumentation alarm/trip setpoints. The ODCM contains a list and graphical description of the specific sample locations for the radiological environmental monitoring program.

Configurations of the liquid and gaseous radwaste treatment systems are also included.

The ODCM will be maintained at the Station as the reference which details the Radiological Effluent Controls of the V. C. Summer Nuclear Station. Additionally the ODCM will be maintained as the guide for accepted calculational methodologies. Changes in calculation methods or parameters will be incorporated into the ODCM in order to ensure that the ODCM represents the current methodology in all applicable areas. Computer software to perform described calculations will be maintained current with this ODCM.

Table 1.1-4 (Continued)

TABLE NOTATION

a. The Lower Limit of Detection (LLD) is the smallest concentration of radioactive material in a sample that will yield a net count above background that will be detected with a 95% probability. LLD also yields a 5% probability of falsely concluding that a blank observation represents a real signal.

For a particular measurement system (which may include radiochemical separation):

2.71 + 4.66s b LLD =

(E) (V) (2.22) (Y) (exp) (-t )

Where:

LLD is the a priori lower limit of detection as defined above (as pCi per unit mass or volume). Current literature defines the LLD as the detection capability for the instrumentation only and the MDC, the minimum detectable concentration, as the detection capability for a given instrument procedure and type of sample.

4.66 is a factor which corrects for the smallest activity that has a probability, p, of being detected, and a probability, 1-p, of falsely concluding its presence.

2.71 may be used to account for minor deviations of the Poisson distribution from Normality.

4.66 = 2k 1 + (tb / t s )

k = a constant whose value depends on the chosen confidence level (NRC recommends a confidence level of 95%)

= 1.6545 at 95% confidence level t b = background time t s = sample time s b is the standard deviation of the background counting rate or the counting rate of blank sample as appropriate (as counts per minute).

E is the counting efficiency (as counts per transformation).

ODCM, V. C. Summer, SCE&G: Revision 29 (August 2013) 1.0-11

Table 1.1-4 (Continued)

TABLE NOTATION V is the sample size (in units of mass or volume).

2.22 is the number of transformations per minute per picoCurie.

Y is the fractional radiochemical yield (when applicable).

is the radioactive decay constant for the particular radionuclide.

t is the elapsed time between midpoint of sample collection and time of counting (for plant effluents, not environmental samples).

The value of s b used in the calculation of the LLD for a detection system shall be used on the actual observed variance of the back-ground counting rate or of the counting rate of the blank samples (as appropriate) rather than on an unverified theoretically predicted variance. In calculating the LLD for a radionuclide determined by gamma-ray spectrometry the background should include the typical contributions of other radionuclides normally present in the samples.

Typical values of E, V, Y and t shall be used in the calculation.

It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as a posteriori (after the fact) limit for particular measurement.*

TABLE NOTATION

b. A composite sample is one in which the quantity of liquid sampled is proportional to the quantity of liquid waste discharged and in which the method of sampling employed results in a specimen which is representative of the liquids released.

c. To be representative of the quantities and concentrations of radioactive materials in liquid effluents, samples shall be composited in proportion to the rate of flow of the effluent stream. Prior to analyses, all samples taken for the composite shall be thoroughly mixed in order for the composite sample to be representative of the effluent release.

d. A batch release is the discharge of liquid wastes of a discrete volume. Prior to sampling for analyses, each batch shall be isolated, and then thoroughly mixed, by a method described in ODCM Section 2.0, to assure representative sampling.

e. A continuous release is the discharge of liquid wastes of a nondiscrete volume; e.g., from a volume of system that has an input flow during the continuous release.

f. The principal gamma emitters for which the LLD specification applies exclusively are the following radionuclides: Mn-54, Fe-59, Co-58, Co-60, Zn-65, Mo-99, Cs-134, Cs-137, and Ce-141. Ce-144 shall also be measured, but with an LLD of

-6 5 X 10 . This list does not mean that only these nuclides are to be detected and reported. Other peaks which are measurable and identifiable, together with the above nuclides, shall also be identified and reported.

ODCM, V. C. Summer, SCE&G: Revision 23 (September 1999) 1.0-43

1.5 BASES B/1.1 LIQUID EFFLUENTS B/1.1.1 Radioactive Liquid Effluent Monitoring Instrumentation The radioactive liquid effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents. The alarm/trip setpoints for these instruments shall be calculated in accordance with the procedures in the ODCM to ensure that the alarm/trip will occur prior to exceeding 10 times the concentration levels specified in 10 CFR 20, Appendix B, Table 2, Column 2. The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50.

B/1.1.2 Concentration This control is provided to ensure that concentration of radioactive materials released in liquid waste effluents from the site (see Technical Specification Figure 5.1-4) will be less than 10 times the concentration levels specified in 10 CFR Part 20, Appendix B, Table 2, Column 2. It provides operational flexibility for releasing liquid effluents in concentrations to follow the Section II.A design objectives of Appendix I to 10 CFR 50. This limitation provides additional assurance that the levels of radioactive materials in bodies of water outside the site will result in exposures within:

(1) the Section II.A design objectives of Appendix I, 10 CFR 50, to an individual 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 radionuclide and its Effluent concentration in air (submersion) was converted to an equivalent concentration in water. This specification does not affect the requirement to comply with the annual limitations of 10 CFR 20.1301(a).

B/1.1.3 Dose This control is provided to implement the requirements of Sections II.A, III.A and IV.A of Appendix I, 10 CFR Part 50. The CONTROLS ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 1.0-44

implement the guides set forth in Section II.A. of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents will be kept as low as is reasonably achievable. Also, for fresh water sites with drinking water supplies which can be potentially affected by plant operations, there is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 40 CFR 141. The dose calculations in the ODCM implement the requirements in Section III.A of Appendix I that conformance with guides of Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of an individual through appropriate pathways 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 NUREG-0133, Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants, section 4.3. NUREG-0133 implements Regulatory Guide 1.109, Revision 1, October 1977 (Section C.1 and Appendix A) and Regulatory Guide 1.113, April 1977.

Regulatory Guide 1.109, October 1977, is titled 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. Regulatory Guide 1.113, April 1977, is titled Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I.

B/1.1.4 Liquid Waste Treatment 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 that the appropriate portions of this system be used when specified 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 Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section II.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 ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 1.0-45

fraction of the dose design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50, for liquid effluents.

B/1.2 GASEOUS EFFLUENTS B/1.2.1 Radioactive Gaseous Effluent Monitoring Instrumentation The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases of gaseous effluents. The alarm/trip setpoints for these instruments shall be calculated in accordance with the procedures in the ODCM to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20. The OPERABILITY and use of this instrumentation is consistent with the requirements of General Design Criteria 60, 63 and 64 of Appendix A to 10 CFR Part 50.

B/1.2.2 Dose Rate This control along with controls 1.2.3 and 1.2.4 provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a member of the public in an unrestricted area, either at or beyond the site boundary in excess of the design objectives of Appendix I to 10 CFR 50. This control is provided to ensure that gaseous effluent from all units on the site will be appropriately controlled yet provides operational flexibility for releasing gaseous effluents to satisfy the section II.B and II.C design objectives of Appendix I to 10 CFR 50.

The restrictions of Control 1.2.3 along with limited occupancy times for a member of the public within the site boundary are sufficient to control exposure to gaseous effluent within 10 CFR 20, Appendix B, Table 2, Column 1 effluent concentrations.

The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to an individual at or beyond the site boundary to less than or equal to 500 mrem/year to the total body or to less than or equal 3000 mrem/year to the skin. These release rate limits also restrict, at all times, the corresponding thyroid dose rate above ODCM, V. C. Summer, SCE&G: Revision 29 (August 2013) 1.0-46

background to a child via the inhalation pathway to less than or equal to 1500 mrem/year.

This control does not affect the requirement to comply with the annual limitations of 10 CFR 20.1301(a).

B/1.2.3 Dose - Noble Gases This control is provided to implement the requirements of Sections II.B, III.A and IV.A of Appendix I, 10 CFR Part 50. The CONTROLS implement the guides set forth in Section II.B of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the release of radioactive material in gaseous effluents will be kept as low as is reasonably achievable. The Surveillance Requirements implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of an individual through appropriate pathways is unlikely to be substantially underestimated. The dose calculations established in the ODCM for calculating the doses due to the actual release rates of radioactive noble gases in gaseous effluents are consistent with the methodology provided in NUREG-0133, Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants, section 5.3. NUREG-0133 implements Regulatory Guide 1.109, Revision 1, October 1977 and Regulatory Guide 1.111, Revision 1, July 1977. Regulatory Guide 1.109 is entitled 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 1.111 is entitled Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors, Revision 1, July 1977. The ODCM equations provided for determining the air doses at the site boundary are based upon the historical average atmospheric conditions.

This control applies to the release of gaseous effluents from all reactors at the site.

ODCM, V. C. Summer, SCE&G: Revision 29 (August 2013) 1.0-47

B/1.2.4 Dose-Radioiodines, Tritium and Radioactive Materials in Particulate Form This control is provided to implement the requirements of Sections II.C, III.A and IV.A of Appendix I, 10 CFR Part 50. The Limiting Conditions for Operation are the guides set forth in Section II.C of Appendix I. The ACTION statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A Appendix I to assure that the releases of radioactive materials in gaseous effluents will be kept as low as is reasonably achievable. The ODCM calculational methods specified in the Surveillance Requirements implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of an individual through appropriate pathways in unlikely to be substantially underestimated. The ODCM calculational methods for calculating the doses due to the actual release rates of the subject materials are consistent with the methodology provided in NUREG-0133, Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants, section 5.3. NUREG-0133 implements Regulatory Guide 1.109, Revision 1, October 1977 and Regulatory Guide 1.111, Revision 1, July 1977. Regulatory Guide 1.109 is entitled Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix ,

Revision 1, October 1977 and Regulatory Guide 1.111 is entitled Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors, Revision 1, July 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions. The release rate controls for radioiodines, tritium, and radioactive materials in particulate form are dependent on the existing radionuclide pathways to man, in the unrestricted area. The pathways which were examined in the development of these calculations were: 1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man and 4) deposition on the ground with subsequent exposure of man.

ODCM, V. C. Summer, SCE&G: Revision 24 (May 2006) 1.0-48

This specification applies to the release of gaseous effluents from all reactors at the site.

B/1.2.5 Gaseous Radwaste Treatment The OPERABILITY of the GASEOUS RADWASTE TREATMENT SYSTEM and the VENTILATION EXHAUST TREATMENT SYSTEM ensures that the systems will be available for use whenever gaseous effluents require treatment prior to release to the environment. The requirement that the appropriate portions of these systems be used, when specified, provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept as low as is reasonably achievable. This specification implements the requirements of 10 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50, and the design objectives given in Section II.D of Appendix I to 10 CFR Part 50.

The specified limits governing the use of appropriate portions of the systems were specified as a suitable fraction of the dose design objectives set forth in Sections II.B and II.C of Appendix I, 10 CFR Part 50, for gaseous effluents.

B/1.3 RADIOACTIVE EFFLUENTS: TOTAL DOSE The control is provided to meet the dose limitations of 40 CFR 190 which have been incorporated into 10 CFR 20.1301(d) and 10 CFR 72.104. The specification requires the preparation and submittal of a Special Report whenever the calculated doses from plant radioactive effluents exceed twice the design objective doses of Appendix I. For sites containing up to 4 reactors, it is highly unlikely that the resultant dose to a member of the public will exceed the dose limits of 40 CFR 190 if the individual reactors remain within twice the 10 CFR 50 Appendix I dose design objectives and if direct radiation doses from the units (including outside storage tanks, etc.) are kept small. Direct radiation due to ISFSI must be included.

The Special Report will describe a course of action which should result in the limitation of dose to a member of the public for 12 consecutive months to within the 40 CFR 190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the member of the public from other uranium fuel cycle sources is negligible, with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 5 miles must be considered. If the dose to any member of ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 1.0-49

the public is estimated to exceed the requirements of 40 CFR 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR 190 have not already been corrected), in accordance with the provisions of 40 CFR 190.11, is considered to be a timely request and fulfills the requirements of 40 CFR 190 until NRC staff action is completed. The variance only relates to the limits of 40 CFR 190 and does not apply in any way to other dose requirements for dose limitation of 10 CFR 20, as addressed in ODCM Controls 1.1.2.1 and 1.2.2.1. An individual is not considered a member of the public during any period in which he/she is engaged in carrying out any operation which is part of the nuclear fuel cycle.

Demonstration of compliance with the limits of 40 CFR 190 or with the design objectives of Appendix I to 10 CFR 50 will be considered to demonstrate compliance with the 0.1 rem limit of 10 CFR 20.1301.

B/1.4.1 Monitoring Program The radiological monitoring program required by this control provides measurements of radiation of radioactive materials in those exposure pathways and for those radionuclides, which lead to the highest potential radiation exposures of individuals resulting from the station operation. This monitoring program thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways. The initially specified monitoring program will be effective for at least the first three years of commercial operation.

Following this period, program changes may be initiated based on operational experience.

The detection capabilities required by Table 1.4-3 are state-of-the-art for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system and not as a posteriori (after the fact) limit for a particular measurement. Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions. Occasionally background fluctuations, unavoidably small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors will be identified and described in the Annual Radiological Environmental Operating Report.

ODCM, V. C. Summer, SCE&G: Revision 25 (January 2007) 1.0-50

B/1.4.2 Land Use Census This control is provided to ensure that changes in the use of unrestricted areas are identified and that modifications to the monitoring program are made if required by the results of this census. The best survey information from the door-to-door, aerial or consulting with local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. Restricting the census to gardens of greater than 500 square feet provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were used, 1) that 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and 2) a vegetation yield of 2 kg/square meter.

B/1.4.3 Interlaboratory Comparison Program The requirement for participation in an Interlaboratory Comparison Program is provided to ensure that independent checks on the precision and accuracy of the measurements of radioactive material in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring in order to demonstrate that the results are reasonably valid.

ODCM, V. C. Summer, SCE&G: Revision 25 (January 2007) 1.0-51

1.6 REPORTING REQUIREMENTS 1.6.1 Annual Radiological Environmental Operating Report 1.6.1.1 Routine radiological environmental operating reports covering the operation of the unit during the previous calendar year shall be submitted prior to May 1 of each year. The initial report shall be submitted prior to May 1 of the year following initial criticality.

1.6.1.2 The Annual Radiological Environmental Operating Report shall include summaries, interpretations, and an analysis of trends of the results of the radiological environmental surveillance activities for the report period, including a comparison with preoperational studies, operational controls (as appropriate), and previous environmental surveillance reports and an assessment of the observed impacts of the plant operation on the environment. The reports shall also include the results of land use censuses required by ODCM Specification 1.4.2.1. If harmful effects or evidence of irreversible damage are detected by the monitoring, the report shall provide an analysis of the problem and a planned course of action to alleviate the problem.

The Annual Radiological Environmental Operating Report shall include summarized and tabulated results in the format of Regulatory Guide 4.8, December 1975 of all radiological environmental samples taken during the report period. In the event that some results are not available for inclusion with the report, the report shall be submitted noting and explaining the reasons for missing results.

2.0 LIQUID EFFLUENT 2.1 Liquid Effluent Monitor Setpoint Calculation The Virgil C. Summer Nuclear Station is located on the Monticello Reservoir which provides supply and discharge for the plant circulating water. This reservoir also provides supply and discharge capacity for the Fairfield Pumped Storage Facility. The Parr Reservoir located below the pumped storage facility is formed by the Parr Dam.

There are two analyzed release pathways and sources of dilution for liquid effluents: the circulating water discharge canal and the liquid effluent line to the penstocks of the pumped storage facility. All liquid effluent pathways discharge to one of these release points. Generally speaking, very low concentrations of radioactive waste are discharged to the circulating water discharge while higher concentrations of radioactive waste are released to the penstocks of the pumped storage facility during the generation cycle.

The calculated setpoint values will be regarded as upper bounds for the actual setpoint adjustments. That is, setpoint adjustments are not required to be performed if the existing setpoint level corresponds to a lower count rate than the calculated value.

Setpoints may be established at values lower than the calculated values, if desired.

Calculated monitor setpoints may be added to the ambient background count rate.

GENERAL NOTE: If no discharge is planned for a specific pathway or if the sum of the effluent concentrations of gamma emitting nuclides equals zero, the monitor setpoint should be established as close to background as practical to prevent spurious alarms and yet alarm should an inadvertent release occur.

2.1.2 Liquid Radwaste Effluent Line Monitors (RM-L5, RM-L7, RM-L9)

Liquid Radwaste Effluent Line Monitors provide alarm and automatic termination of release functions prior to exceeding 10 times the concentration limits specified in 10 CFR 20, Appendix B, Table 2, Column 2 at the release point to the unrestricted area. To meet this specification, the alarm/trip setpoints for liquid effluent monitors and flow measurement devices are set to assure that the following equation is satisfied:

cf 10C ECL (1)

F+f where:

C ECL = the effluent concentration limit specified in 10 CFR 20 Appendix B, Table 2, Column 2. Note that Control 1.1.2.1 limits release concentrations to 10 times the Appendix B, Table 2, Column 2 values.

c = the setpoint, in µCi/mI, of the radioactivity monitor measuring the radioactivity concentration in the effluent line prior to dilution and subsequent release; the setpoint, which is inversely proportional to the volumetric flow of the effluent line and proportional to the volumetric flow of the dilution stream plus the effluent stream, represents a value which, if exceeded, would result in concentrations exceeding 10 times the effluent concentrations of 10 CFR 20 in the unrestricted area.

At the Virgil C. Summer Nuclear Station the Liquid Waste Processing System (LWPS) and the Nuclear Blowdown System (NBS) both discharge to the penstocks of the Fairfield Pumped Storage (FPS) Facility through a ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-6

common line. The available dilution water flow (F dp ) is assumed to be 90 percent of the flow through the FPS penstock(s) to which liquid effluent is being discharged and is dependent upon operational status of the FPS Facility. The waste tank flow rates (f dm and f db ) and the monitor setpoints (c M , c B and c C ) are set to meet the condition of equation (1) for a given effluent concentration, C. The three monitor setpoints are determined in accordance with the monitor system configuration for this discharge pathway. The LWPS discharges through RM-L5, which has setpoint c M for alarm/control functions over releases from either Waste Monitor Tanks 1 or

2. The Nuclear Blowdown discharges through RM-L7, which has setpoint c B for alarm/ control functions over releases from the Nuclear Blowdown Monitor Tank. These two release pathways merge into a common line monitored by RM-L9, which has setpoint c C for control functions over the common effluent line. Although the piping is arranged so that simultaneous batch releases from the two systems could be practiced, operational releases shall be from only one of the two batch systems at any given time.

The method by which their setpoints are determined is as follows:

1) The isotopic concentration for a waste tank to be released is obtained from the sum of the measured concentrations as determined by the analysis required in Table 1.1-4:

C = C i

i g

g + Ca + Cs + C t + C f (2) where:

Ci = the concentration of nuclide i, in µCi/mI, as determined by the analysis of the waste sample.*

C g

= the sum of the concentrations C g of each measured gamma g emitting nuclide observed by gamma-ray spectroscopy of the waste sample, in µCi/mI.

Values for C a , C s , C t and C f will be based on most recent available composite sample analyses as required by Table 1.14.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-7

Cs* = the concentration of Sr-89 and Sr-90 in liquid waste as determined by analysis of the quarterly composite sample, in

µCi/mI.

Ct* = the measured concentration of H-3 in liquid waste as determined by analysis of the monthly composite sample, in µCi/mI.

Cf* = the measured concentration of Fe55 in liquid waste as determined by analysis of the quarterly composite sample , in

µCi/mI.

The C g term will be included in the analysis of each batch; terms for alpha, strontium, Fe-55, and tritium shall be included as appropriate*. Isotopic concentrations for both the Waste Monitor Tanks (WMT) and the Nuclear Blowdown Monitor Tank (NBMT) may be calculated using equation (2).

Prior to being sampled for analysis, the contents of a tank shall be isolated and recirculated. The minimum recirculation time shall be:

t r = 2V/f r (3) tr = the minimum time for recirculating the contents of a tank prior to sampling.

V = the volume of liquid in the tank to be sampled.

fr = the recirculation flow rate used to mix the contents of a tank.

This is done to ensure that a representative sample will be obtained.

Mechanical mixers shall ensure a similar minimum turnover.

Based on most recent available composite sample analysis as required by Table 1.1-4.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-8

2) Once isotopic concentrations for either Waste Monitor Tank or the Nuclear Blowdown Monitor Tank have been determined, these values are used to calculate a Dilution Factor, DF, which is the ratio of dilution flow rate to tank flow rate(s) required to assure that 10 times the limiting concentration of 10 CFR 20, Appendix B, Table 2, Column 2 are met at the point of discharge for whichever tank is having its contents discharged.

SF = the safety factor; a conservative factor used to compensate for engineering and measurement uncertainties.

= 0.5, Corresponding to a 100 percent variation.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-9

3) The maximum permissible discharge flow rate, f t , may be calculated for the release of either the WMT or NBMT. First the appropriate Dilution Factor is calculated by applying equation (4), using the appropriate concentration ratio term (i.e. M or B). An additional safety factor is used for based on 90 percent FPS Station expected flowrate.

Then,

( Fdp + f dx ) (0.9) Fdp f t = (0.9) for Fdp >> f dx (6)

DF DF where:

F dp = dilution flow rate to be used in effluent monitor setpoint calculations, as corrected for any recirculated radioactivity:

C ir Fdp = Ft (1 ) (7) i 10 (E CL) i where:

Ft = the flow rate through the Fairfield Pumped Storage Station penstock(s) to which radioactive liquids are being discharged. F t should normally fall between 2500 and 44800 cfs.

C ir = the concentration of radionuclide i, in µCi/mI, in the intake of Fairfield Pumped Storage Station (that is, in the Monticello Reservoir). Inclusion of this term will correct for possible long-term buildup of radioactivity due to recirculation and for the presence of activity recently released to the Monticello Reservoir by plant activities.

For expected discharges of liquid wastes, the summation will be much less than 1.0 and can be ignored (Reference 6).

f dx = the flow rate of the tank discharge, either f dm or f db .

f db = flow rate of Nuclear Blowdown Monitor Tank discharge.

(Conservatively this value will be either zero, if no release is ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 2.0-10

to be conducted from this system, or the maximum measured capacity of the discharge pump if a release is to be conducted.)

f dm = flow rate of Waste Monitor Tank discharge. (Conservatively this value will either be zero, if no release is to be conducted from this system, or the maximum measured capacity of the discharge pump if a release is to be conducted.)

DF = the Dilution Factor from Step 2.

If f t f dx , the release may be made as planned and the flow rate monitor setpoints should be established as in Step 4 (below). Because F dp is normally very large compared to the maximum discharge pump capacities for the Waste Monitor Tank and the Nuclear Blowdown Monitor Tank, it is extremely unlikely that f t < f dx. However, if a situation should arise such that f t < f dx, steps must be taken to assure that equation (1) is satisfied prior to making the release. These steps may include decreasing f dx by decreasing the flow rate of f dm or f db ,

and/or increasing F dp .

When new candidate flow rates are chosen, the calculations above should be repeated to verify that they combine to form an acceptable release. If they do , the establishment of flow rate monitor setpoints may proceed as follows in Step 4. If they do not, the choice of candidate flow rates must be repeated until an acceptable set is identified.

Note that if DF 1, the waste tank concentration for which the calculation is being performed includes safety factors in Step 2 and meets the instantaneous release rate limits without further dilution.

Even though no dilution would be required, there will be no discharge if minimum dilution flow is not available, since the penstock minimum flow interlock will prevent discharge.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-11

4) The dilution flow rate*, F, is established at 90 percent of the expected available dilution flow rate.

5) The radiation monitor setpoints may now be determined based on the values of C i , F, and f which were specified to ensure releases are limited to 10 times the values of 10 CFR 20, Appendix B, Table 2, Column 2. The monitor response is primarily to gamma radiation, therefore, the actual setpoint is based on C g .

The setpoint concentration, c, is determined as follows:

c Cg XA (9) g A= Adjustment factor which will allow the setpoint to be established in a practical manner for convenience and to prevent spurious alarms.

A = f t / f dx (10)

If A 1, Calculate c and determine the maximum value for the actual monitor setpoint (cpm) from the monitor calibration graph.

Setpoints for flow rates are administrative limits.

ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 2.0-12

If A < 1, No release may be made. Reevaluate the alternatives presented in Step 3.

NOTE: If calculated setpoint values are near actual concentrations planned for release, it may be impractical to set the monitor alarm at this value. In this case a new setpoint may be calculated following the remedial methodology presented in Step 3 for the case of f t < f dx .

Within the limits of the conditions stated above, the specific monitor setpoint concentrations for the three liquid radiation monitors RM-L5, RM-L7, and RM-L9 are determined as follows:

2.1.2.1 RM-L5, Waste Monitor Tank Discharge Line Monitor:

CM Cg ( A) (11)

M g

C M is in µCi/mI

See GENERAL NOTE under 2.1.

2.1.2.2 RM-L7, Nuclear Blowdown Monitor Tank Discharge Line Monitor:

C B C g ( A ) (12)

B g

C B is in µCi/ml NOTE: In no case should discharge be made directly from the Nuclear Blowdown Holdup Tank to the penstocks.

See GENERAL NOTE under 2.1.

2.1.2.3 RM-L9, Combined Liquid Waste Processing System and Nuclear Blowdown Waste Effluent Discharge Line Monitor The monitor setpoint concentration on the common line, c C , should be the same as the setpoint ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-13

concentration for the monitor on the active individual discharge line (i.e., c M , or c B as determined above):

C C MAX (C M , C B ) (13)

See GENERAL NOTE under 2.1.

NOTE: In all cases, c M , c B , and c c are the setpoint concentration values in µCi/ml. The actual monitor setpoints (cpm) for RM-L5, RM-L7, and RM-L9 are determined from the calibration graph for the particular monitor. Initially, the calibration curves were determined conservatively from families of response curves supplied by the monitor manufacturers. A sample is shown in Figure 2.1-1. As releases occur, a historical correlation will be prepared and placed in service when sufficient data are accumulated.

2.1.2.4 RML-5 / RML-9 Alternate Setpoint Methodology For low gamma activity releases with relatively high tritium concentrations, an alternate setpoint methodology can be used as follows which assumes that the tritium concentrations will not increase greater than the value used in the calculation. The tritium concentration used for the calculation is established based on known plant conditions.

Setpoint concentration , c , is determined as follows:

In the Virgil C. Summer Nuclear Station liquid waste effluent system design, there exists a mechanism for discharging liquid wastes via the Industrial Sanitary Waste System. The sample point prior to discharge is one of the Waste Monitor Tanks. The analysis requirements are the requirements listed in Table 1.14.

ODCM, V. C. Summer, SCE&G: Revision 29 (August 2013) 2.0-14A

This effluent pathway shall only be used when the following condition is met for all radionuclides, i:

[Ci ] M [Ci ] LLD (14)

[C i ] M = the concentration of radionuclide i in the waste contained within the Waste Monitor Tank serving as the holding facility for sampling and analysis prior to discharge , in µCi/mI.

[C i ] LLD = the Lower Limit of Detection, (LLD) for radionuclide i in the liquid waste in the Waste Monitor Tank as determined by the analysis required in Table 1.1-4, in µCi/mI.

When the conditions of equation (14) are met, liquid waste may be released via the Industrial and Sanitary Waste System pathway. The RM-L5 setpoint should be established as close to background as practical to prevent spurious alarms and yet alarm should an inadvertent high concentration release occur.

2.1.4 Steam Generator Blowdown, Turbine Building Sump, and Condensate Demineralizer Backwash Effluent Lines (RM-L3, RM-L10, RM-L8, RM-L11)

Concentrations of radionuclides in the liquid effluent discharges made via the Turbine Building Sump, Steam Generator Blowdown, and Condensate Demineralizer Backwash are expected to be very low or nondetectable. The first two releases are expected to be continuous in nature and the last a batch release. All will be sampled in an appropriate manner as specified in Table 1.1-4 of the ODCM. The Steam Generator Blowdown Monitors, the Turbine Building Sump Monitor, and the Condensate Demineralizer Backwash Monitor provide alarm and automatic termination.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-15

In reality, all of these effluent pathways utilize the circulating water as dilution to the effluent stream, with the circulating water discharge canal being the point of release into an unrestricted area. Steam Generator Blowdown Effluent may be released to the Circulating Water either directly in the Condenser outflow (the normal flow path) or in the first hours following startup via the Industrial and Sanitary Waste System (ISWS) for chemical reasons. The Turbine Building Sump and Condensate Demineralizer Backwash Effluents enter Circulating Water via the sumps and ponds of the Industrial and Sanitary Waste System.

CO3 To ensure compliance with ODCM specification 1.1.2.1, normally no dilution is assumed for discharges to the Industrial and Sanitary Waste System. Additionally, releases are normally limited to 1 ECL to ensure that the conditions of 10 CFR 20.1301 are met. These administrative controls provide assurance that ODCM specification 1.1.2.1 would not be compromised in the event circulating water dilution is lost. To add operational flexibility for abnormal conditions (radionuclide concentration in Turbine Building sump > 1 ECL), discharges from the Turbine Building sump and concentrations in the discharging ponds of the ISWS may exceed the operational objective, 1 ECL, provided circulating water dilution is sufficient to ensure compliance with ODCM specification 1.1.2.1 and liquid effluents are being discharged in compliance with ODCM specification 1.1.4.1.

Two separate setpoint calculations are given for Turbine Building sump discharges (RM-L8). Section 2.1.4.2.1 describes the setpoint calculation normally used, limiting discharges to 1 ECL. Section 2.1.4.4 provides an alternate setpoint methodology which may be used during abnormal conditions. RM-L8 setpoints are considered in compliance with ODCM specification 1.1.1.1 provided the setpoints CO3 are adequate to prevent releases in excess of ODCM specification 1.1.2.1.

Two mutually exclusive setpoint calculation processes are outlined below for steam generator blowdown. Section 2.1.4.1 is to be used whenever Steam Generator Blowdown is being released directly to the Circulating Water in the Condenser outflow, which is the normal mode. Section 2.1.4.2 is to be used whenever Steam Generator Blowdown own is being released to the Industrial and Sanitary Waste System, or diverted to the Nuclear Blowdown Processing System, both of which are alternate modes.

Normally, water collected by the Nuclear Blowdown Processing System has very low specific activity. This water may be processed to the Turbine Building sump.

NOTE: When Circulating Water is unavailable for effluent dilution and water is being directed to a releasing ISWS pond, releases containing activity above LLD (excluding tritium) should be discouraged via pathways which lead to it. Steam Generator Blowdown should be diverted to the Nuclear Blowdown ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-16

Processing System. Condensate Demineralizer Backwash may be diverted to the Turbine Building sump or not released. Turbine Building sump effluent should be processed through temporary demineralizers or diverted to the Excess Liquid Waste Processing System. (These steps are to keep the calculated dose to individuals as low as reasonably achievable.)

An option for directing water from the TBS with specific activity > LLD to a non releasing pond is provided in Section 2.1.4.5.

2.1.4.1 Steam Generator Blowdown Effluent Direct to Circulating Water (Normal Mode)

Equation (1) is again used to assure that effluents are in compliance with the aforementioned specification:

cf 10 C ECL (F + f)

The available dilution water flow (F dc ) is dependent upon the mode of operation of the Circulating Water System. Any change in this value will be accounted for in a recalculation of equation (1). The Steam Generator Blowdown flow rate (f ds ) and the Steam Generator Blowdown monitor setpoints (c Sa and c Sb ) are set to meet the condition of equation (1).

RM-L3, the first monitor in the Steam Generator Blowdown discharge pathway, alarms and terminates release of the stream. The discharge is then automatically diverted to the Nuclear Blowdown Processing System. RM-L10, the last monitor in the Steam Generator Blowdown discharge pathway, alarms and terminates the release. Thus, RM-L10 is redundant to RM-L3 and the setpoint (c Sb ) will be determined in the same manner as RM-L3(c Sa ).

The method by which the monitor setpoints are determined is as follows:

1) The isotopic concentrations for any release source to be or being released are obtained from the sum of the measured ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 2.0-17

concentrations as determined in Table 1.1-4. Equation (2) is again employed for this calculation:

C = C i

i g

g + Ca + Cs + Ct + C f where:

C i

= the sum of the measured concentrations as determined by the i analysis of the waste sample, in µCi/mI.

C g

= the sum of the concentrations C g of each measured gamma g emitting nuclide observed by gamma-ray spectroscopy of the waste sample, in µCi/mI.

Ca = the measured concentration C a of alpha emitting composite sample, in µCi/mI.

Cs = the measured concentrations of Sr-89 and Sr-90 in liquid waste as determined by analysis of the most recent available quarterly composite sample, in µCi/mI.

Ct = the measured concentration of H-3 in liquid waste determined by analysis of the monthly composite sample, in µCi/mI.

Cf = the measured concentration of Fe-55 in liquid waste as determined by analysis of the most recent available quarterly composite sample, in µCi/mI.

Isotopic concentrations for the Steam Generator Blowdown System effluent , the Turbine Building Sump Effluent, and the Condensate Demineralizer Backwash effluent may be calculated using equation (2).

2) Once isotopic concentrations for the Steam Generator Blowdown have been determined, these values are used to calculate a Dilution Factor (DF) which is the ratio of the total dilution flow rate to effluent stream flow rate ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-18

required to limit the effluent concentration at the point of discharge to less than 10 times the values in 10 CFR 20, Appendix B, Table 2, Column 2.

Ci DF = S ÷ SF (15) i 10 (E CL)i Cg Ca Cs Cf Ct DF = + + + + ÷ SF (16) g 10(ECL) g 10(ECL) a 10(ECL) s 10(ECL) f 10(ECL) t s where:

Ci = C g , C a , C s , C f , and C t ; measured concentrations as defined in Step 1. Terms C a , C s , C f , and C t will be included in the calculation as appropriate.

Ci = the sum of the ratios of the measured concentration of S

nuclide i to its limiting value ECL i for the Steam Generator i 10( ECL)i Blowdown effluent.

ECL i = ECL g , ECL a , ECL s , ECL f , and ECL t are limiting concentrations of the appropriate radionuclide from 10 CFR, Part 20, Appendix B, Table 2, Column 2 limits.

SF = the same generic term as used in Section 2.1.2, Step 2.

= 0.5

3) The maximum permissible effluent discharge flow rate, f d , may now be calculated for a release from the Steam Generator Blowdown. An additional safety factor is used for .based on 90 percent of the expected flow rate of the Circulating Water System during the time of release.

Based ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 2.0-19

(Fdc +f ds ) (0.9)Fdc f d = (0.9) for Fdc >> f ds (17)

DF DF where:

F dc = Dilution flow rate for use in effluent monitor setpoint calculations, corrected for any recirculated activity:

C ir Fdc = Fd 1 (18) i 10(ECL) i where:

Fd = the flow rate of the Circulating Water System during the time of the release. F d should normally fall between 1.78 X 105 and 5.34 X 105 gpm when the plant is operating and should be 5000 gpm when the plant is shutdown and the Circulating Water Jockey pump is operating.

C ir = the concentration of radionuclide i, in µCi/mI, in the Circulating Water System intake, (that is, in the Monticello Reservoir). Inclusion of this term will correct for possible long-term buildup of radioactivity due to recirculation and for the presence of activity recently released to the Monticello Reservoir by plant activities. For expected discharges of liquid wastes, the summation will be much less than 1.0 and can be ignored (Reference 6).

f ds = Flow rate of Steam Generator Blowdown discharge. (This value normally will be either zero, if no release is to be conducted, or the maximum rated capacity of the discharge pump (250 gpm), if a release is to be conducted.)

ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 2.0-20

Note that the equation is valid only for DF > 1; for DF 1, the effluent concentration meets the release criteria without dilution as well as being in compliance with the conservatism imposed by the Safety Factor in Step 2.

If f d f ds , releases may be made as planned. Because F dc is normally very large compared to the maximum discharge pump capacity of the Steam Generator Blowdown System, it is extremely unlikely that f d < f ds . However, if a situation should arise such that f d < f ds , steps must be taken to assure that equation (1) is satisfied prior to making the release. These steps may include diverting Steam Generator Blowdown to the Nuclear Blowdown Processing System or decreasing the effluent flow rate.

When new candidate flow rates are chosen, the calculations above should be repeated to verify that they combine to form an acceptable release. If they do, the establishment of flow rate monitor setpoints should proceed as follows in Step 4. If they do not provide an acceptable release, the choice of candidate flow rates must be repeated until an acceptable set is identified.

4) The dilution flow rate for minimum flow rate, F, is established at 90 percent of the expected available dilution flow rate.

5) The Steam Generator Monitor setpoints may be specified based on the values of C i , F, and f which were specified to ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 2.0-21

limit discharge within 10 times the limits of 10CFR 20, Appendix B, Table 2, Column 2. Since the monitor responds primarily to gamma radiation, therefore, the actual setpoint is based on C g . The monitor setpoint in cpm which corresponds to the calculated value c is taken from the monitor calibration graph.

(See NOTE, page 2.0-14.) The setpoint concentration, c, is determined as follows:

c Cg X B (20) g B = fd / fds (21)

If B 1, Calculate c and determine the maximum value for the actual monitor setpoint (cpm) from the monitor calibration graph.

If B < 1, No release may be made. Reevaluate the alternatives presented in step 3.

NOTE: If the calculated setpoint value is near actual concentrations being released or planned for release, it may be impractical to set the monitor alarm at this value. In this case a new setpoint may be calculated following the remedial methodology presented in steps 3 and 4 for the case f d < f ds .

Within the conditions stated above, the specific monitor setpoint concentrations for the two steam generator blowdown monitors RM-L3 and RM-L10 are calculated as shown on the following page.

2.1.4.1.1 For RM-L3, Steam Generator Blowdown Discharge initial monitor, and for RM-L10, Steam Generator Blowdown Discharge final monitor:

See GENERAL NOTE under 2.1.

2.1.4.2 Turbine Building Sump and Condensate Demineralizer Backwash (Normal Mode)

For conservatism, the Turbine Building Sump and Condensate Demineralizer Backwash monitor setpoints (c T and c D ) will claim no dilution from the Circulating Water, and will be set at the applicable concentration limit. That is:

C ECL c (23)

The Turbine Building sump monitor, RM-L8, alarms and terminates release upon exceeding the monitor setpoint (c T ). The discharge can then be manually diverted to the Excess Waste Processing System.

RM-L11, the Condensate Demineralizer Backwash monitor, alarms and terminates release upon exceeding the monitor setpoint (c D). The discharge may then be manually diverted to the Turbine Building sump or simply delayed.

The Turbine Building Sump and Condensate Demineralizer Backwash monitor setpoints are to be established independently of each other and without crediting dilution. They are to be based on the measured radionuclide concentrations of the effluent stream and are to ensure that discharge concentrations do not exceed the ECLs specified in 10 CFR 20, Appendix B, Table 2, Column 2 prior to discharge.

For each effluent stream, a concentration factor (CF) is calculated by summing the ratios of detected radionuclides in the ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-23

effluent stream to the applicable ECLs, the calculated values normalize the effluent mixture to terms of ODCM Control 1.1.2.1 release criteria and includes a safety factor for engineering uncertainty.

Ci CF = ÷ SF (24) i (ECL)i Ci CFT = ÷ SF (25) i (ECL)i T Ci CFD = ÷ SF (26) i (ECL)i D where:

Ci = the sum of the ratios of the measured concentration of nuclide i T

i (E CL) i to its limiting value ECL i for the Turbine Building sump effluent.

Ci = the sum of the measured concentration of nuclide i (in liquid D

i (E CL) i only) to its limiting value ECL i for the Condensate Demineralizer Backwash effluent.

CF T = the concentration factor for the Turbine Building Sump Effluent.

CF D = the concentration factor for the Condensate Demineralizer Backwash Effluent.

SF = the generic engineering safety factor used in Section 2.1.2, Step 2.

= 0.5 If CF 1, calculate c and determine the actual monitor setpoint (cpm) from the calibration curve.

If CF > 1, no release may be made via this path. The release must either be delayed, diverted, or processed.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-24

If the concentration factor cannot be reduced to less than or equal to 1, proceed to section 2.1.4.4 or 2.1.4.5 for additional guidance for processing Turbine Building Sump releases.

Within the limits of the conditions stated above, the specific monitor setpoint concentrations for RM-L8 and RM-L11 may now be calculated. Because they are primarily sensitive to gamma radiation, their setpoints will be based on the concentrations of gamma emitting radionuclides as follows:

2.1.4.2.1 For RM-L8, Turbine Building Sump Discharge Monitor:

c T Cg T ÷ CFT (27) g Where:

C g T = The gamma isotopic concentration of the Turbine Building sump g effluent as obtained from the sum of the measured concentrations determined by the analysis required in ODCM Table 1.1-4, in µCi/mI.

CF T = The Turbine Building sump Effluent Concentration Factor from equation (25).

See GENERAL NOTE under 2.1.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-25

2.1.4.2.2 For RM-L11, Condensate Demineralizer Backwash Discharge Monitor:

c D C g D ÷ CFD (28) g where:

= The gamma isotopic concentration of the Condensate Demineralizer C g D g Backwash effluent (including solids) as obtained from the sum of the measured concentrations determined by the analysis required ODCM Table 1.1-4, in µCi/mI.

CF D = The Condensate Demineralizer Backwash Effluent Concentration Factor from equation (26).

See GENERAL NOTE under 2.1.

2.1.4.3 Steam Generator Blowdown Effluent Not Directly to Circulating Water (Alternate Mode)

Equation (23) is again used to assure that effluents are in compliance with the aforementioned specification before dilution in the receiving water:

C ECL c Because dilution is not considered in the setpoint calculation, it is not necessary to calculate maximum permissible discharge flow rates or anticipated available dilution flow rate.

The functions of the two monitors whose setpoints are to be established are described in Section 2.1.4.1 above. The method for the determination is as follows:

1) If a release is found to be permissible, flow rate monitors for the active effluent streams (Steam Generator Blowdown - f ds ,

Turbine Building sump - f dt , and Condensate Demineralizer - f dd )

may have their setpoints established at any operationally convenient value.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-26

2) The Concentration Factor of equation (24) is again used to ensure the permissibility of the release.

Ci CF = ÷ SF i (ECL)i Ci CFS = S ÷ SF (29) i (ECL)i All terms are defined in subsection 1.1.3.1 and subscript S refers to the Steam Generator Blowdown Effluent.

If CF 1, calculate c and determine the actual monitor setpoint (cpm) from the calibration curve.

If CF > 1, no release may be made via this path. The release must either be delayed or diverted for additional processing.

Within the above limitation, setpoint concentrations may now be calculated for the two effluent monitors. Because they are primarily sensitive to gamma radiation, their setpoints will be based on the concentrations of gamma emitting radionuclides as follows:

2.1.4.3.1 For RM-L3, Steam Generator Blowdown Discharge initial monitor, and RML-10, Steam Generator Blowdown Discharge final monitor:

cSa or cSb Cg S ÷ CFS (30) g ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-27

Where:

C g = The isotopic concentration of the Steam Generator Blowdown g S effluent as obtained from the sum of the measured concentrations determined by the analysis required in ODCM Table 1.1-4, in

µCi/mI.

CF S = The Steam Generator Blowdown Effluent Concentration Factor from equation (29).

See GENERAL NOTE under 2.1.

CO3 2.1.4.4 Turbine Building Sump (Abnormal Conditions)

Provided circulating water is available, 1 to 3 circulating water pumps, effluent exceeding 1 ECL may be released from the Turbine Building sump to the industrial and sanitary waste system, using the setpoint in this section, provided the following conditions are met:

1) Instantaneous release rate limits of ODCM Specification 1.1.2.1 are not exceeded in the circulating water discharge canal.

2) Annual average concentrations of radioactivity in ISWS ponds will not exceed 1 ECL.

3) The limits of ODCM specification 1.1.4.1 will not be exceeded with actual liquid effluent releases over a 31 day period.

4) Average discharge flow does not exceed values used in setpoint determination.

In addition, the source of radioactivity should be identified and isolated.

Radionuclide concentration in Turbine Building sump effluent should be restored to <1 ECL as soon as possible and normal setpoint reestablished. Radionuclide concentration in Pond 6B should be restored to < LLD (excluding tritium) using dilution as necessary (normal flow from the TBS would normally be adequate). Turbine Building sump samples should be obtained and analyzed every twelve hours while the alternate setpoint is being used to ensure that the setpoint remains conservative with respect to the isotopic mixture and to ensure offsite doses are within ODCM limits.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-28

Alternate setpoint methodology for Turbine Building sump (RM-L8) is available to ensure operational flexibility in the event radioactivity is detected in the Turbine Building sump > 1 ECL and the release would result in minimal offsite dose. The alternate setpoint methodology is not intended to be used continuously. To remove restrictions on operation of circulating water, pond concentrations should be restored to < LLD as soon as possible. The setpoint methodology follows:

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-29

2.1.4.5 Turbine Building Sump - Special Considerations During Station Shutdowns During periods in which circulating water (CW) is not available for diluting Turbine Building Sump (TBS) discharges, effluent from the TBS may be directed to a non-releasing pond and offsite dose calculations required by Specification 1.1.3.1 deferred until CW is restored. RM-L8 setpoint requirement specified by Specification 1.1.1.1 is not applicable when directing water from the TBS to a non-releasing ISWS pond provided the following conditions are met.

1) Sufficient freeboard is available in the non-releasing pond to ensure that pond contents will not be released to the CW discharge canal prior to reestablishing CW flow.

2) Release of ISWS contents will be in compliance with Specifications 1.1.2.1, 1.1.3.1 and 1.1.4.1 once CW flow has been reestablished.

3) ISWS pond radioactivity will not exceed 1 ECL.

4) TBS samples are obtained and analyzed every 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months while water is being directed to a non-releasing pond.

5) Sample non-releasing pond within 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months of adding water > 1 ECL and every 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months thereafter while TBS discharge concentrations exceed 1 ECL.

Once samples have been obtained and release acceptability determined, RM-L8 setpoint may be increased to 2 times indication to allow release of sump contents to a non-releasing pond.

Demonstrating compliance with item 3 can be performed by calculations using TBS samples and discharge volumes or by sampling ISWS ponds.

2.2 Dose Calculation for Liquid Effluents The method of this section is to be used in all cases for calculating doses to individuals from routine liquid effluents. Five notes at the end of the section confirm the values which certain parameters are to be assigned in some special cases.

2.2.1 Liquid Effluent Dose Calculation Parameters Section of Term Definition Initial Use A i = the site related ingestion dose commitment factor 2.2.2 to the total body or any organ , for each identified principal gamma and beta emitter listed in Table 2.2-3 in mrem-ml per hr-µCi.

BF i = Bioaccumulation Factor for nuclide i, in fish, 2.2.2 pCi/Kg per pCi/l, from Table 2.2-1.

C ik = the average concentration of radionuclide, i, in 2.2.2 undiluted liquid effluent during time period t k from any liquid released, in µCi/ml.

DF i = a dose conversion factor for nuclide, i, for adults 2.2.2 in preselected organ, , in mrem/pCi found in Table 2.2-2.

D = the cumulative dose commitment to the total 2.2.2 body or any organ, , from the liquid effluents for the total time period, t k in mrem (Ref. 1).

Dw = Dilution Factor from the near field area within 2.2.2 one-quarter mile of the release points to the potable water intake for adult water consumption; for V. C. Summer, D w = 1.

Fk = the near field average dilution factor for C ik 2.2.2 during any liquid effluent release.

Ko = 1.14 x 105, units conversion factor = 2.2.2 (106 pCi/µCi) (103 ml/l) ÷ 8760 hr/yr t k = the length (in hours) of a time period over which 2.2.2 concentrations and flow rates are averaged for dose calculations.

UF = 21 kg/yr, fish consumption (adult) (Reference 3). 2.2.2 Uw = 730 kg/yr, water consumption (adult) (Reference 2.2.2 3).

Z = applicable near-field dilution factor when no 2.2.2 additional dilution is to be considered; Z = 1.

ODCM, V. C. Summer, SCE&G: Revision 28 (July 2012) 2.0-32

2.2.2 Methodology The dose contribution from all radionuclides identified in liquid effluents released to unrestricted areas is calculated using the following expression:

D = Ai tk Cik Fk (31) i k =1 Ai = Ko ( (Uw / Dw ) + UF BFi ) DFi (32)

(average undiluted liquid waste flow)

Fk = (33)

(average flow from the discharge structure) (Z)

NOTE 1: If radioactivity in the Monticello Reservoir (C ir ) becomes > the LLD specified in ODCM, Table 1.1-4, that concentration must be included in the Dose determination. For this part of the dose calculation, F k = 1 and t k = the entire time period for which the dose is being calculated.

NOTE 2: Prior to termination of Circulating Water Pumps, an assessment of the dose resulting from pond radioactivity concentrations and discharge flow rates from the Industrial And Sanitary Waste System (ISWS) will be performed as follows. Sampling of the liquid in the ISWS wilt be initiated, and the measured concentrations of radionuclides will be used in the dose calculations with F k = 1 and t k = the entire time period for which the dose is being calculated.

NOTE 3: For releases through the ISWS pathway when circulating water is not available, dose projections for assessment of release acceptability should be based on the most representative samples obtained from in plant sumps. Normally sump samples are also used to assess actual release. However, due to the ultraconservative assumptions when circulating water is not available, i.e. dose calculations are based on radioactive material concentration in the discharge stream regardless of release volume, representative samples from the ISWS may be used to evaluate impact of releases.

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-33

NOTE 4: During periods when the Circulating Water Pumps are in operation, any releases to the ISWS are to be credited with dilution in Circulating Water for dose calculation purposes, even though such dilution is normally not claimed in the setpoint calculation. When taken in union with the note above, this procedure results in some overestimation of dose to the population because discharges made to the ISWS just before loss of Circulating Water will be counted twice in the dose calculation process.

NOTE 5: If radioactivity in the Service Water becomes > LLD as determined by the analysis required by ODCM, Table 1.1-4, that concentration must be included in the Dose determination. For this part of the dose calculation, F k = 1 and t k = the entire time since the last Service Water sample was taken.

2.3 Liquid Effluent Releases through the Neutralization Basin Releases of slightly contaminated liquids from pathways feeding the Neutralization Basin (Pond 007) through Circulating Water (CW) may be made under strictly controlled conditions.

Releases from these pathways (e.g., NaOH sump, RWST sump) will be allowed if the following conditions are adhered to in controlling the radioactive materials released.

2.3.1 Rainwater Tank Rainwater collected in the RWST sump is pumped to the RWST Pit Drain Tank (Rainwater Tank) for analysis and subsequent release. Normally the rainwater is sampled, found to contain no detectable radioactivity, and is released to the environment via the storm drain system. If measurable amounts of radioactive materials are found in Rainwater Tank samples, the tank may be pumped to a Waste Monitor Tank and released without processing. In order to allow for operational flexibility, the Rainwater Tank containing radioactive materials may be drained to the NaOH sump and discharged to the circulating water (CW) system via the Neutralization basin (007). The following constraints are to be applied for releases through this pathway:

(1) At least one CW pump must be used for dilution to release through this pathway.

(2) Chemistry Services must be notified to verify that conditions in the Neutralization Basin are such that additions to the basin can be made.

(3) Using the Rainwater Tank analysis and available circulating water, a release calculation must be performed that shows that releases will be less than 6.0E-4 mrem (whole body) and 2.0E-3 mrem (any organ). These limits represent 1% of unprocessed effluent 31-day dose limits (ODCM Section 1.1.4.1).

ODCM, V. C. Summer, SCE&G: Revision 21 (March 1996) 2.0-35

(4) If these limits are met, the Rainwater Tank may be drained through the NaOH sump to the Neutralization Basin. Chemistry will then release the Neutralization Basin contents through circulating water as soon as possible once their procedural and NPDES release criteria are met.

2.3.2 NaOH Spray Tank and Stored NaOH (1) The same limits and conditions as 2.3.1(1-4) apply for releases from the NaOH sump.

(2) Samples should be obtained and analyzed during performance of NaOH Spray Tank activities that require the draining of NaOH from the tank or sight glass.

(3) If the sample show concentrations of radionuclides that would exceed the dose limits above and the tank must have liquid removed from it, the contaminated NaOH may be drained to appropriate holding containers for temporary storage. Once the conditions for release become favorable (e.g.

return of CW), the containers used for temporary storage may be sampled and analyzed for release. If the dose limitations in 2.3.1 (3) are met and Chemistry approval is obtained, a release permit is generated and the containers can be drained through the NaOH sump or emptied directly to the Neutralization Basin for release through CW.

This is an optional treatment pathway which provides processing flexibility in the event processing through excess liquid waste is not desirable. Since a temporary demineralizer is used for this optional treatment pathway, operability tests specified in ODCM specification 1.1.4.1 are not required. To ensure adequacy of the RM-L8 setpoint while using the alternate process pathway, samples must be obtained from the discharge side of the demineralizers or condenser cleaning sump and analyzed every twelve hours.

CO1 3.1.2 Station Vent Noble Gas Monitors (RM-A3 and RM-A4)

For the purpose of implementation of section 1.2.1 of the ODCM, the alarm setpoint level for the station vent noble gas monitors will be calculated as follows:

Sv = count rate of the plant vent noble gas monitor (= S vp for RM-A3) or the containment purge noble gas monitor (= S vc for RM-A4) at the alarm setpoint level.

0.25 x R t x D TB (34)

< the lesser of or 0.25 x R s x D SS (35) 0.25 = the safety factor applied to each of the two vent noble gas monitors (plant vent and containment purge) to assure that the sum of the releases has a combined safety factor of 0.5 which allows a 100 percent margin for cumulative uncertainties of measurements.

D TB = Dose rate limit to the total body of an individual

= 500 mrem/yr Rt = count rate per mrem/yr to the total body

= Cv / (( X / Q) x Fv x Ki X iv ) (36) i Dss = Dose rate limit to the skin of the body of an individual in an unrestricted area.

= 3000 mrem/year.

Rs = count rate per mrem/yr to the skin.

= Cv ÷ [ X / Q x Fv x ( Li + 11. Mi ) X iv ] (37) i X iv = the measured concentration of noble gas radionuclide i in the last grab sample analyzed for vent v, µCi/ml. (For the plant vent, grab samples are taken at least ODCM, V. C. Summer, SCE&G: Revision 13 (June 1990) 3.0-5

monthly. For the 6 and 36 containment purge lines, the sample is taken just prior to the release and also monthly, if the release is continuous.)

Fv = the flow rate in vent v, cc/sec. (1 cc/sec = 0.002119 cfm)

Cv = count rate, (cpm) of the monitor on station vent v corresponding to grab sample noble gas concentrations, X iv , as determined from the monitors calibration curve; i.e.,

product of the monitor response curve slope (cpm/uCi/ml) and the sum of the noble gas concentrations in the grab sample (uCi/ml). (Initial calibration curves of the type shown in Figure 2.1-1 have been determined conservatively from families of response curves supplied by the monitor manufacturers. As releases occur, a historical correlation will be prepared and placed in service when sufficient data are accumulated.)

X/Q = the highest annual average relative concentration in any sector, at the site boundary (seven year average).

= 6.3E-6 sec/m3 in the ENE sector.

Ki = total body dose factor due to gamma emissions from isotope i (mrem/yr per µCi/m3) from Table 3.1-1.

Li = skin dose factor due to beta emissions from isotope i (mrem/yr per µCi/m3) from Table 3.1-1.

1.1 = mrem skin dose per mrad air dose.

Mi = air dose factor due to gamma emissions from isotope i (mrad/yr per µCi/m3) from Table 3.1-1.

ODCM, V. C. Summer, SCE&G: Revision 28 (July 2012) 3.0-6

NOTE: At plant startups when no grab sample analysis is available for the continuous releases, the Alternate Methodology of Section 3.1.4 must be used.

3.1.3 Waste Gas Decay System Monitor (RM-A10)

The permissible conditions for discharge through the waste gas decay system monitor (RM-A10) will be calculated in a manner similar to that for the plant vent noble gas monitor. In the case of the waste gas system, however, the discharge flow rate is continuously controllable by valve HCV-014 and permissible release conditions are therefore defined in terms of both flow rate and concentration.

Therefore, RM-A10 is used only to insure that a representative sample was obtained.

For operational convenience, (to prevent spurious alarms due to fluctuations in background) the setpoint level will be established at 1.5 times the measured waste concentration.

The maximum permissible flow rate will be set on the same basis but include the engineering safety factor of 0.5. The RM-A10 setpoint level S d is defined as:

Sd 1.5c (38) where:

c = count rate in CPM of the waste gas decay system monitor corresponding to the measured concentration (taken from the monitor calibration curves).

The maximum permissible waste gas flow rate f w (cc/sec) is calculated from the maximum permissible dose rates at the site boundary according to:

fw < the lesser of ft or fs (39)

ODCM, V. C. Summer, SCE&G: Revision 13 (June 1990) 3.0-7

ft = the maximum permissible discharge rate based on total body dose rate.

= 0.25 x DTB / [ X / Q x 1.5 X id Ki ] (40) i fs = the maximum permissible discharge rate based on skin dose rate.

= 0.25 x DSS / [ X / Q x 15

. X id ( Li + 11

. Mi )] (41) i X id = the concentration of noble gas radionuclide i in the waste gas decay tank whose contents are to be discharged, as corrected to the pressure of the discharge stream at the point of the flow rate measurement. The maximum discharge pressure as governed by the diaphragm valve, 7896, is 30 psia.

NOTE: The factor of 1.5 in the denominators of equations (40) and (41) places f w on the same basis as S d .

When a discharge is to be conducted, valve HCV-014 is to be opened until (a) the waste gas discharge flow rate reaches 0.9 x f w or (b) the count rate of the plant vent noble gas monitor RM-A3 approaches its setpoint, whichever of the above conditions is reached first.

When no discharges are being made from the Waste Gas Decay System, the RM-A10 setpoint should be established as near background as practical to prevent spurious alarms and yet alarm in the event of an inadvertent release.

3.1.4 Alternative Methodology for Establishing Conservative Setpoints As an alternate to the methodology of section 3.1.2, to minimize necessity for frequent adjustment of setpoint, a conservative setpoint may be calculated as follows:

For a plant vent:

Rt = conservative count rate per mrem/yr to the total body (Xe-133 detection, Kr-89 dose).

ODCM, V. C. Summer, SCE&G: Revision 18 (September 1994) 3.0-8

= C v ÷ [ X / Q x K kr-89 x X v x F v ],

(42) where:

Xv = a concentration of Xe-133 chosen to be in the operating range of the monitor on vent v, µCi/cc.

Cv = the count rate in CPM of the monitor on vent v corresponding to X v

µCi/cc of XE-133.

K Kr-89 = total body dose factor for Kr-89, the most restrictive isotope from Table 3.1-1.

Rs = count rate per mrem/yr to the skin.

= C v ÷ [ X / Q x (L Kr-89 + 1.1M kr-89 ) x X v x F v ] (43) where:

L Kr-89 = skin dose factor for Kr-89, the most restrictive isotope from Table 3.1-1.

M Kr-89 = air dose factor for Kr-89, the most restrictive isotope, from Table 3.1-1.

For the waste gas decay system:

ft = the conservative maximum permissible discharge rate based on Kr-89 total body dose rate.

= 0.25 x D TB ÷ [ X / Q x 1.5 x X d K kr-89 ] (44) fs = the conservative maximum permissible discharge rate based on Kr-89 skin dose rate.

= 0.25 x D SS ÷ [ X / Q x 1.5 x X d x (L Kr-89 + 1.1M Kr-89 )] (45)

ODCM, V. C. Summer, SCE&G: Revision 13 (June 1990) 3.0-9

Xd = the total concentration of noble gas radionuclides in the waste gas decay tank whose contents are to be discharged, as corrected to the pressure of the discharge stream at the point of the flow measurement.

c = count rate in cpm of the waste gas decay system monitor corresponding to X d µCi/cc of Kr-85.

3.1.5 Oil Incineration 3.1.5.1 Oil incinerator was removed from service in 2010 and the structure decommissioned under Engineering Change Request 71498.

3.1.6 Meteorological Release Criteria for Batch Releases Planned gaseous batch releases (WGDT) and will be performed during favorable meteorology. Limiting releases to favorable meteorology provides assurance that release conditions will be conservative with respect to annual average dispersion values, (X / Q, X / Q') . Favorable meteorology is defined in Table 3.1-2.

3.2.4 For the purpose of initial assessments of the impact of unplanned gaseous releases, dose calculations for the critical receptor in each affected sector may be performed using section 3.2.3.1 and section 3.2.3.2 equations as follows:

(1) For each affected sector, X/Q and D/Q will be calculated for one mile and critical receptor locations using actual meteorological conditions occurring during the unplanned release. Actual X/Q and D/Q values will be compared to annual average dispersion coefficients (X / Q, X / Q', and X / Q'). The more limiting dispersion coefficients will be used along with methodology in sections 3.2.3.1 and 3.2.3.2 for the initial assessment.

(2) The location of the critical receptors and the pathways j which should be analyzed are shown in Table 3.2-2. (For very rough calculations, the annual average dispersion coefficients

( X / Q and D / Q) for each receptor are shown in Table 3.2-3.)

3) The R aij for the appropriate exposure pathways and age groups will be selected from Table 3.2-1 ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 3.0-17

See note on the following page for the method used to identify these controlling receptors.

- If a cow were located at 5.0 miles (8,000 meters) in this sector, an infant consuming only its milk would receive a greater total radiation dose than would the real receptor listed. However, such an infant would not be the Maximum Exposed Individual for the site.

ODCM, V. C. Summer, SCE&G: Revision 30 (March 2016) 3.0-49

NOTE: The controlling receptor in each sector was identified in the following way. Receptor locations and associated pathways were obtained from the August 1991 field survey.

A child was assumed at each location, except that where a milk cow was listed, an infant was assumed. X / Q and D / Q for each candidate receptor was calculated using five year averaged meteorological data. XOQDOQ-82 software was used to analyze the meteorological data. Expected annual releases of each nuclide were taken from Table 5.2-2 of Reference 5. The specific dispersion values for each candidate are used with the methodology of ODCM section 3.2.3.2 to calculate a hypothetical dose. The controlling receptor for each sector was then chosen as the candidate receptor with the highest total annual dose of any candidate receptor in the given sector. All listed pathways are in addition to inhalation and ground plane exposure.

Annual average relative dispersion and deposition values for the receptor locations in Table 3.2-2. Values were calculated from 5 year averaged meteorological data using the XOQDOQ-82 software. Dispersion values were calculated assuming ground-level release, open terrain recirculation, dry depletion, and using decay with a half-life of 8.0 days. As a result of the analysis described in the note to Table 3.2-2, the location of the maximum exposed individual for the site is assumed to be the vegetable garden at 1.1 miles in the E sector. Therefore, the site X / Q' and D / Q' (Section 3.2.3.2 and following) are those from this table for that location.

Page 4 of 4 NOTES

1. Site-specific annual average absolute humidity. For each month, an average absolute humidity was calculated from the 7 years of monthly average temperatures in Table 2.3-49 of Reference 4 and 5 years of monthly average dew points in Table 2.3-64 of Reference 4. The 12 monthly values were averaged to obtain the annual average of 8.84 gm/m3. Section 5.2.1.3 of Reference 1 gives a default value of 8 gm/m3.) The default value of 8 gm/m3 from Section 5.2.1.3 of Reference 1 was used in the calculation of the R aij values for Tritium found in Table 3.2-1, providing a marginally more conservative result.

2. Typically beef cattle are raised all year on pasture. Annual land surveys have indicated that the small number of goats raised within 5 miles typically are used for grass control and not food or milk. Nevertheless, the goats were treated as full meat and milk sources where present, despite the fact that their numbers cannot sustain the meat consumption rates of Table E-5 of Reference 3.

3. According to the August 1990 land use census, dairy cattle possibly graze at 4.9 miles in the West sector. If dairy cattle graze at this location, the dose to an infant consuming milk from these animals would be less than the dose received by the critical receptor identified for the sector. No other milking activity within five miles of the plant was identified. These values are included for reference only.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM VIRGIL C. SUMMER NUCLEAR STATION TABLE 4.0-1 TABLE NOTATION

1. The dose shall be calculated for the maximum organ and age group, using the guidance/methodology contained in Regulatory Guide 1.109, Revision 1 and the parameters particular to the Site. The locations are selected based on the potential for the highest exposure.

2. Milking animal and garden survey results will be analyzed annually. Should the survey indicate new dairying activity the owners shall be contacted with regard to a contract for supplying sufficient samples. If contractual arrangements can be made, Site(s) will be added for additional milk sampling up to a total of 3 Indicator Locations.

3. Time composite samples are samples which are collected with equipment capable of collecting an aliquot at time intervals which are short (e.g. hourly) relative to the compositing period.

4. At least once per 18 days.

5. Not to exceed 35 days.

6. At least once per 100 days.

7. At least once per 200 days

8. Milk and forage sampling at the control location is only required when locations meeting the criteria of VII(A) are being sampled.

9. Sample site locations are based on 5 year average meteorological analysis.

10. Location numbers refer to Figures 4.0-1 through 4.0-4.

11. Though generalized areas are noted for simplicity of sample site enumeration, airborne, water and sediment sampling is done at the same location whereas biological sampling sites are generalized areas in order to reasonably assure availability of samples.

DESCRIPTION CONTINUED: Organ dose calculation methodology for gaseous releases is revised allowing calculation of dose to individual organs instead of calculation of dose to a hypothetical maximum organ . Tables 3.2.1 , 3.2-2 , 3.2-3, 3.2-4 ,

3.2-5 , 3.2-6 were deleted and replaced with a new table providing dose conversion factors for all organs, by pathway and age groups. Liquid release control methodology for Waste Mon itor tanks and Steam Generator Blowdown is revised moving a safety factor from formulas 7 and 18 to 6 an 17, respectively, for consistency with RADEAS methodology. Reference to setpoints for dilution and discharge flow for liquid release deleted for clarity (previously identified as administrative). Ni-63 was also added as a required isotope for Waste Monitor Tanks. 1-131 and Cs-137 site related ingestion dose factors for Kidney in Table 2.2-3 corrected. ISFSI added as a fuel cycle source , 6 TLD locations added to Table 1.4-1 , and reporting requirements added.
