Attachment 2 Supplemental Information McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 Carbon-14 Carbon-14 (C-14), with a half-life of 5730 years, is a naturally occurring isotope of carbon produced by cosmic ray interactions in the atmosphere. Nuclear weapons testing in the 1950s and 1960s significantly increased the amount of C-14 in the atmosphere. C-14 is also produced in commercial nuclear reactors, but the amounts produced are much less than those produced naturally or from weapons testing.

In Regulatory Guide 1.21, Revision 2, "Measuring, Evaluating, and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste", the NRC recommends U.S. nuclear power plants evaluate whether C-14 is a "principal radionuclide", and if so, report the amount of C-14 released. Improvements over the years in effluent management practices and fuel performance have resulted in a decrease in gaseous radionuclide (non-C-14) concentrations, and a change in the distribution of gaseous radionuclides released to the environment. As a result, many sites show C-14 has become a "principal radionuclide" for the gaseous effluent pathway, as defined in Regulatory Guide 1.21, Rev. 2. McGuire Nuclear Station 2017 ARERR contains estimates of C-14 radioactivity released in 2017, and estimates of public dose resulting from the C-14 effluent.

Because the dose contribution of C-14 from liquid radioactive waste is much less than that contributed by gaseous radioactive waste, evaluation of C-14 in liquid radioactive waste is not required (Ref. Reg. Guide 1.21, Rev. 2). The quantity of gaseous C-14 released to the environment can be estimated by use of a C-14 source term scaling factor based on power generation (Ref. Reg. Guide 1.21, Rev. 2). Many documents provide information related to the magnitude of C-14 in typical effluents from commercial nuclear power plants. Those documents suggest that nominal annual releases of C-14 in gaseous effluents are approximately 5 to 7.3 curies from PWRs (Ref. Reg. Guide 1.21, Rev. 2). A more recent study recommends a higher C-14 gaseous source term scaling factor of approximately 9.0 to 9.8 Ci/GWe-yr for a PWR (Westinghouse) (Ref. EPRI 1021106). For the McGuire Nuclear Station 2017 ARERR a source term scaling factor of 9.4 Ci/GWe-yr is assumed. Using a source term scaling factor of 9.4 Ci/GWe-yr and actual electric generation (MWe-hrs) from McGuire Nuclear Station in 2017 results in a site total C-14 gaseous release estimate to the environment of 2.09+01 Curies. 70% of the C-14 gaseous effluent is assumed to be from batch releases and 30% of C-14 gaseous effluent is assumed to be from continuous releases through the unit vents (ref. IAEA Technical Reports Series no. 421, "Management of Waste Containing Tritium and Carbon-14", 2004; EPRI 1021106).

C-14 releases in PWRs occur primarily as a mix of organic carbon and carbon dioxide released from the waste gas system. Since the PWR operates with a reducing chemistry, most, if not all, of the C-14 species initially produced are organic (e.g., methane). As a general rule, C-14 in the primary coolant is essentially all organic with a large fraction as a gaseous species. Any time the RCS liquid or gas is exposed to an oxidizing environment (e.g. during shutdown or refueling), a slow transformation from an organic to an inorganic chemical form can occur. Various studies documenting measured C-14 releases from PWRs suggest a range of 70% to 95% organic with an average of 80%

organic with the remainder being CO 2 (Ref. EPRI TR-105715). For the McGuire Nuclear Station 2017 ARERR a value of 80% organic C-14 is assumed.

Public dose estimates from airborne C-14 are performed using dose models in NUREG-0133 and Regulatory Guide 1.109. The dose models and assumptions used are documented in the McGuire ODCM. The estimated C-14 dose impact on the maximum organ dose from airborne effluents released from McGuire Nuclear Station in 2017 is well below the 10CFR50, Appendix I, ALARA design objective (i.e., 15 mrem/yr per unit).

Attachment 2 Supplemental Information McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 Overall Estimate of Error for Effluent Radioactivity Release Reported The estimated percentage of overall error for both Liquid and Gaseous effluent release data at McGuire Nuclear Station has been determined to be +/- 30.3%. This value was derived by taking the square root of the sum of the squares of the following discrete individual estimates of error:

1. Flow Rate Determining Devices = +/-20%

2. Counting Statistical Error = +/-20%

3. Calibration Error = +/-10%

4. Calibration Source Error = +/-2.5%

5. Sample Preparation Error = +/-3%

Attachment 5 Unplanned Offsite Releases McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 McGuire Nuclear Station experienced no unplanned offsite liquid effluent releases in 2017.

McGuire Nuclear Station experienced one (1) unplanned offsite gaseous effluent releases in 2017. Summary is described below.

Unplanned release to the Unit 2 Vent, Reference NCR# 02111243 Event Summary:

On March 24, 2017 at 16:14 the Unit 2 Vent gas rad monitor increased to -251 counts per minute (cpm) above background (bkg) resulting in a Trip 1 alarm. The highest count rate observed from the Unit Vent gas monitor was 277 cpm. Normal 2 EMF 36L bkg was determined to be 25 cpm . RP trending of the Unit 2 radiation monitor 2 EMF 36L indicated an increased count rate and remained elevated above bkg for 49 minutes. At -1620, a Trip 2 control room annunciator alarm was received on OEMF41 monitoring point 11 (NB Evaporator area). The alarm occurred when Radwaste restarted the B WG Compressor, which had spuriously tripped. 0 EMF 41 point 11 reached a maximum count rate of 1135 cpm at 16:40. Control Room Operators notified RP Shift. It was also noted that a pressure drop of

-9 psig was identified from the in-service Waste Gas Decay Tank (WGDT) "E" starting -16:05 hrs. This pressure drop 3

equates to a loss of 367 .3 ft of gas.

The NB evaporator rupture disk failed when an inline check valve failed and allowed WG system to over-pressurize the evaporator.

A sample was obtained from WGDT "E and the total noble gas activity released during the event was conservatively determined to be 2.79E-02 Curies. The release was reported on Gaseous Waste Release (GWR) report# 2016024.

No SLC or T/S limits were challenged by this release.

The total release of noble gas radioactivity was evaluated against off site dose limits using current ODCM methodology. Procedure AD-RP-ALL-2003 "Investigation of Unusual Radiological Occurrences" was completed to document the event (Assignment 04).

Safety Significance:

The health and safety of the public were not compromised by this event. Calculated dose and dose rate to the Total Body, Skin, Gamma Air, and Beta Air were all significantly below the limits specified by Selected Licensee Commitments and the Code of Federal Regulations.

Attachment 6 Assessment of Radiation Dose from Radioactive Effluents to Members of the Public McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 -12/31/2017 40 CFR Part 190 Uranium Fuel Cycle Dose Calculation Results In accordance with the requirements of 40 CFR Part 190, the annual dose commitment to any member of the general public shall be calculated to assure that doses are limited to 25 millirems to the total body or any organ with the exception of the thyroid which is limited to 75 millirems. The fuel cycle dose assessment for McGuire Nuclear Station includes liquid and gaseous effluent dose contributions from McGuire Nuclear Station and direct and air-scatter dose from the onsite ISFSI. No other uranium fuel cycle facility contributes significantly to the maximum exposed individual. Included in the gaseous effluent dose calculations is an estimate of the dose contributed by Carbon-14 (Ref. Attachment 2, Supplemental Information, of this report for further information). The combined dose to a maximum exposed individual from effluent releases and direct and air-scatter dose from the ISFSI is below 40 CFR Part 190 limits as shown by the following summary.

Note: The 40 CFR Part 190 effluent dose analysis to the maximum exposed individual from liquid and gas releases includes the dose from noble gases (i.e., total body and skin).

Direct and air-scatter radiation dose contributions from the onsite ISFSI have been determined from the 10 CFR 72.212 Evaluation Report, MAGNASTOR, Revision 05. The maximum dose rate to the nearest real individual from the ISFSI is conservatively calculated to be less than 4 mrem/yr.

The attached excerpt from the 10 CFR 72.212 Evaluation Report, MAGNASTOR, Revision 05 is provided to document the method used to calculate the dose from ISFSI as less than 4 mrem/yr to the nearest real individual.

Total dose from liquid and gaseous effluents from McGuire Nuclear Station and direct and air-scatter dose from the onsite ISFSI is conservatively estimated to be less than 8 mrem/yr to the nearest real individual. This meets the 40 CFR Part 190 requirements of an annual dose commitment to any member of the general public of less than 25 mrem total body or any organ and 75 mrem to the thyroid.

Attachment 6 Assessment of Radiation Dose from Radioactive Effluents to Members of the Public McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 10 CFR 72.212 Evaluation Report, MAGNASTOR, Revision 04 6.0 10 CFR 72.212(b)(5)(iii) Radioactive Materials in Effluents and Direct Radiation 6.1 Purpose 10 CFR 72.212(b)(5)(iii) requires the general licensee to perform written evaluations, before use and before applying the changes authorized by an amended CoO to a cask loaded under the initial CoO or an earlier amended CoC, that establish that the requirements of 10 CFR 72.104 have been met. A copy of this record shall be retained until spent fuel is no longer stored under the general license issued under 10 CFR 72.210.

10 CFR 72.104 provides the regulatory criteria for radioactive materials in effluents and direct radiation from an independent spent fuel storage installation (ISFSI) during normal operation and anticipated occurrences. Specifically, 10 CFR 72.104(a) limits the annual dose equivalent to any real individual who is located beyond the controlled area to 25 mrem to the whole body, 75 mrem to the thyroid, and 25 mrem to any other critical organ. This dose equivalent must include contributions from (1) planned discharges of radioactive materials (radon and its decay products excepted) to the general environment, (2) direct radiation from ISFSI operations, and (3) any other radiation from uranium fuel cycle operations within the region. In addition, 10 CFR 72.104(b) requires that operational restrictions be established to meet as low as is reasonably achievable (ALARA) objectives for radioactive materials in effluents and direct radiation levels associated with ISFSI operations. Also, 10 CFR 72.104(c) requires that operational limits be established for radioactive materials in effluents and direct radiation levels associated with ISFSI operations to meet the above-mentioned dose limits.

This section provides the written evaluation required by 10 CFR 72.212(b )(5)(iii), demonstrating Duke Energy's compliance with the requirements of 10 CFR 72.104 for the MNS ISFSI.

6.2 Evaluation This evaluation addresses the radiological dose rate from a composite population of all MNS ISFSI cask types.

6.2.1 §72.104(a) - Dose Limits Duke Energy Engineering Instruction MCEl-0400-241 determined that the distance from the nearest residence to the ISFSI is 0.65 miles (1046 meters). Hence, it is conservative to assume that the closest real individual is at least 700 meters from the ISFSI.

Enercon determined the annual total dose (gamma plus neutron) at a distance of 700 meters from all currently loaded casks (10 TN-32A casks and 28 NAC-UMS casks) to be approximately 1.62 mrem. The evaluation was based on actual cask average burn-up (as loaded) and considering cooling time on the storage pads as of September 1, 2010.

The distance at which this dose is calculated (700 meters) is conservative compared to the distance to the closest real individual.

NAC International determined the annual total dose (gamma plus neutron) at a distance of 700 meters from a (future) 2x6 array of MAGNASTOR casks to be approximately 1.01 mrem (2.02 mrem for two arrays). The evaluation was conservatively based on full cask loads of 37 fuel assemblies at the maximum allowable heat load of 35.5 kW. The distance at which this dose is calculated (700 meters) is conservative compared to the distance to the closest real individual.

The total calculated annual public dose from liquid and gaseous effluent pathways averaged over a ten-year period is less than 4 mrem. No other uranium fuel cycle facility contributes significantly to the dose received by the closest real individual.

Attachment 6 Assessment of Radiation Dose from Radioactive Effluents to Members of the Public McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 Based on the above, the calculated annual dose (performed in December 2015 per Reference 10) revised the annual dose to the closest real individual due to the ISFSI, which is comprised of the currently existing ten TN-32A casks and 28 NAC-UMS casks, and up to two 2x6 arrays of MAGNASTOR casks (see Note below), is determined to be less than 4 mrem, and the estimated annual dose due to McGuire power generation is less than 4 mrem. Hence, the total annual dose to the closest real individual (less than 8 mrem) is within the 10 CFR 72.104(a) limit.

Note: As stated above, up to two 2x6 arrays of MAGNASTOR casks are assumed in this evaluation. The first eight MAGNASTOR casks are planned to be placed on a concrete pad currently containing four NAC-UMS casks. This will conservatively count as one 2x6 array. Additional MA GNASTOR casks will be placed on their own concrete pad (the second 2x6 array). Hence, this §72.104(a) evaluation bounds up to 20 MAGNASTOR casks, arranged as described.

This initiative was developed to ensure timely and effective management of situations involving inadvertent releases of licensed material to ground water. As part of this program, McGuire Nuclear Station monitored 95 wells, 4 surface water points, and 1 leachate pond in 2017.

Wells are typically sampled quarterly or semi-annually. Ground water samples are regularly analyzed for tritium and gamma emitters, with select wells being analyzed for difficult-to-detect radionuclides. No gamma or difficult-to-detect radionuclides, other than naturally occurring radionuclides, were identified in well samples during 2017. Results from sampling during 2017 confirmed existing knowledge of tritium concentrations in site ground water.

Results from sampling during 2017 are shown in the table below.

No events meeting the criteria for voluntary notification per NEI 07-07, Industry Ground Water Protection Initiative, occurred at McGuire Nuclear Station in 2017.

Key to below table.

Not scheduled to be sampled, not sampled due to insufficient NS volume in well, or well inaccessible during outage.

pCi/1 - picocuries per liter.

<MDA - less than minimum detectable activity, typically 250 pCi/1.

the Environmental Protection Agency drinking water standard for 20,000 pCi/1 tritium. This standard applies only to water used for drinking.

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 Section 6 - new Page 12 Added the following to new Page 12:

"Comparison of concurrent data from both the 40 m and 60 m McGuire meteorological towers was made for a limited period of simultaneous operation (August 19 to September 10, 1998) prior to termination of the historical 40 m tower.

Results were documented in the Corrective Action Program (NCR 01697913 or PIP M-98-1240).

The analysis indicated the 40m tower was subject to microscale terrain related impacts due to its location below the dam elevation, near plant buildings. The current 60 m tower location north McGuire has an open exposure and is more representative of regional meteorological conditions."

Change made based on recommendation in DRR 02140589. Add additional details to the description of the correlation of the new 60 meter meteorological tower to the old 40 meter meteorological tower. Change to address comments made by NRC in NTM 02130749.

EXECUTIVE

SUMMARY

The McGuire Nuclear Station (MNS) Offsite Dose Calculation Manual (ODCM) provides the methodology and parameters to be used in the calculation of offsite doses due to normal operation radioactive liquid and gaseous effluents to assure compliance with the dose limitations of the Selected Licensee Commitments (SLCs, UFSAR Chapter

16) and Technical Specifications (TSs ). These dose limitations assure that:

(1) the concentration of radioactive liquid effluents released from the site to the unrestricted area will be limited to 10 times the effluent concentration (EC) levels of 10CFR20, Appendix B, Table 2, and 2.0E-04 µCi/ml for dissolved and entrained noble gases (TS 5.5.5(a)(2), SLC 16.11.1);

(2) the exposures to any individual member of the public from radioactive liquid effluents will not result in doses greater than the ALARA design objectives of 10CFR50, Appendix I or the 10CFR20 limits (TS 5.5.5(a)(4), SLC 16.11.3);

(3) the dose rate at any time at the site boundary from radioactive gaseous effluents will be limited to: for noble gases; less than or equal to 500 mrem/yr to the whole body, and less than or equal to 3000 mrem/yr to the skin; and for iodine-131 and iodine-133, for tritium, and for all radioactive materials in particulate form with half-lives greater than 8 days; less than or equal to 1500 mrem/yr to any organ (TS 5.5.5(a)(7),

SLC 16.11.6);

(4) the exposure to any individual member of the public from radioactive gaseous effluents will not result in doses greater than the ALARA design objectives of 10CFR50, Appendix I or the 10CFR20 limits (TS 5.5.5(a) (8 and 9), SLCs 16.11.8 and 16.11.9); and (5) the dose to any individual member of the public from the nuclear fuel cycle will not exceed the limits of 40CFR190 (TS 5.5.5(a)(l0), SLC 16.11.12).

The methodology and parameters used to assure compliance with the dose limitations described above shall be used to prepare the radioactive liquid and gaseous effluent reports required by the SLCs and Technical Specifications. Dose calculations that demonstrate compliance with 40CFR 190 will be considered to Executive Summary - Page 1 9-10

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 McGuire Nuclear Station Offsite Dose Calculation Manual (ODCM) demonstrate compliance with the 10CFR20 0.1-rem annual dose limit. The ODCM also provides the methodology and parameters to be used in the calculation of radioactive liquid and gaseous effluent monitoring instrumentation alarm/trip setpoints to assure compliance with the concentration and dose rate limitations of the SLCs and Technical Specifications. Software implementing NUREG-0133 methodology is used for the calculation of offsite doses, but the ODCM also provides a method for the calculation of offsite doses when the software is not available.

The ODCM has been prepared as generically as possible in order to minimize the need for revisions. Any changes to the methodology and parameters to be used in this ODCM shall be reviewed by knowledgeable individual(s), and approved by the Station Manager or Radiation Protection Manager prior to implementation. Changes to the ODCM shall be submitted to the Nuclear Regulatory Commission in accordance with the SLCs and Technical Specifications.

The ODCM does not replace any station implementing procedures. Programmatic controls for radioactive effluents and radiological environmental monitoring are contained in the Administrative Controls chapter of the Technical Specifications.

Procedural details for radioactive effluents and radiological environmental monitoring consisting of licensee commitments, applicability, remedial actions, surveillance requirements, and the bases for these requirements are contained in Section 16.11 of the SLCs.

The system produces effluents that can be reused in the plant or discharged to the environment. The means of treatment vary with waste type and desired product in the various systems:

(A) Filtration - Waste sources are filtered during processing. In some cases, such as the Floor Drain Tank (FDT) subsystem of the Liquid Waste System (WL), filtration may be the only treatment required.

(B) Adsorption - Adsorption of halides and organic chemicals by activated charcoal (carbon filter) may be used in treating waste in the Laundry and Hot Shower Tank (LHST). The carbon filter is designed to remove organophosphates and free chlorine. Activated charcoal need not be used when these chemicals are not present (e.g., phosphate detergents are not used at the station). Ion exchange resin or other media may be used in the carbon filter vessel as desired.

(C) Ion Exchange - Ion exchange is used to remove radioactive cations from solution, as in the case of the FDT waste after removal of organics by carbon filtration (adsorption). Ion exchange can also be used in removing both cations (cobalt, manganese) and anions (chloride, fluoride) from evaporator distillates in order to purify the distillates for reuse as makeup water. Distillate from the Boron Recycle Evaporator in the Boron Recycle System (NB) can be treated by this method.

(D) Gas Stripping - Removal of gaseous radioactive fission products is accomplished in the NB Evaporator.

(E) Distillation - Production of pure water from the waste by boiling it away from the contaminated solution which it was originally contafoed is accomplished by the NB evaporator. Proper control of the process will yield water that can be reused for makeup. Polishing of this product can be achieved by ion exchange as pointed out above.

(F) Concentration - In the NB Evaporator, dissolved chemicals are concentrated in the lower shell as water is boiled away. The dilute boron is normally concentrated to 4%

so that it may be reused for makeup to the reactor coolant system.

The design basis for the WG shown schematically in Figure 1.0-2 is the retention, through the plant lifetime, of all the gaseous fission products to be discharged from the reactor coolant system to the Chemical and Volume Control System (NV) and other plant systems to eliminate the need for intentional discharge of radioactive gases from the waste gas holdup tanks. Actual system operation is aimed at maximizing storage time for decay prior to infrequent releases. Unavoidable sources of low level radioactive gaseous discharge to the environment will be from periodic purging operations of the containment, and through the secondary system air ejector. With respect to the former, the potential fission product gas is expected to arise from non-recyclable reactor coolant leakage. With respect to the air ejector, the potential source of fission product gas will be from leakage of the reactor coolant to the secondary system through defects in steam generator tubes. The gaseous waste disposal system includes two waste gas compressors, two catalytic hydrogen recombiners, six gas decay storage tanks for use during normal power generation, and two gas decay storage tanks for use during shutdown and startup operations.

1.0.2.1 GAS COLLECTION SYSTEM The gas collection system combines the waste hydrogen and fission gases from the volume control tanks, the boron recycle and liquid waste gas stripper evaporators, and other sources produced during normal operation or the gas collected during the shutdown degasification (high percentage of hydrogen), and cycles it through the catalytic recombiners to convert hydrogen to water. After the water vapor is removed, the resulting gas stream is transferred from the recombiner into the waste gas decay tanks (WGDTs), where the accumulated activity may be contained in six approximately equal parts. From the decay tanks, the gas flows back to the compressor suction to complete the loop circuit.

1.0.2.2 CONTAINMENT AND AUXILIARY BUILDING VENTILATION Non-recyclable reactor coolant leakage occurring either inside the containment or inside the auxiliary building will generate gaseous activity. Gases resulting from leakage inside the containment atmosphere will be circulated through a charcoal adsorber and a particulate filter prior to release to the atmosphere.

Gases resulting from leakage inside the auxiliary building are released, without further decay, to the atmosphere. The ventilation exhaust from potentially contaminated areas in the auxiliary building is passed through charcoal adsorbers and particulate filters to reduce releases to the atmosphere upon a radiation monitor alarm.

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 McGuire Nuclear Station Offsite Dose Calculation Manual (ODCM) 1.0.2.3 SECONDARY SYSTEMS The gases removed from the secondary system by the air ejectors are discharged to the unit vent. If the secondary system contains activity, the steam generator blowdown may be either discharged directly to the condenser cooling water system or through demineralizers to reduce activity levels.

Gland leak-off steam, which represents a minor source of activity, is routed to the gland condenser. The non-condensable gases are exhausted to the unit vent; the condensables are condensed and drained to the condensate storage tank.

Some low radioactivity secondary system steam releases can occur at the site such as from infrequent lifts or testing of the main steam power operated relief valves (PORVs) and the code safety main steam relief valves. Radioactivity released from secondary system steam releases is documented and included in the site effluent release total.

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 -12/31/2017 McGuire Nuclear Station Offsite Dose Calculation Manual (ODCM) 2.0 RELEASE RATE CALCULATIONS 2.0.1 LIQUID RELEASE RATE LIMIT CALCULATIONS There are two liquid rad waste discharge points to the environment at McGuire; (1) the Condenser Cooling Water System (RC) discharge point to Lake Norman, and (2) the Conventional Waste Water System (WC) and Waste Water Collection Basin (WWCB) discharge point to the Catawba River downstream of Cowan's Ford Dam (See Figure 2.0-1).

2.0.1.1 RC DISCHARGE RELEASE RATE LIMIT CALCULATION Liquid releases to Lake Norman through the RC pathway normally contain the radioactive releases from the site including effluents from the waste monitor tanks and containment ventilation unit condensate drain tanks. The RC discharge point can also contain Turbine Building Sump (TBS) releases, however TBS effluent is normally released through WC. Condenser unwatering (WU) is normally released to the WWCB discharge point. Each unit has four RC pumps that pump 2.5E5 gpm each and provide dilution for releases. Each release path has a radiation monitor (EMF) that is used to monitor the liquid effluent (See Figure 2.0-2).

To comply with Technical Specifications and Selected Licensee Commitments, and to assure that the concentration of radioactive liquid effluents released from the site to the unrestricted area is limited to 10 times the effluent concentrations (ECs) of 10CFR20, Appendix B, Table 2, Column 2, and 2.0E-04 µCi/ml for dissolved and entrained noble gases, the following release rate limit calculation shall be performed for liquid releases to Lake Nonnan via the RC discharge point:

f ~ (F + (DF -1)) Condition: DF > 1.0 Equation 2.1 where:

f the undiluted effluent flow, in gpm.

F the dilution flow available depending on the number (1-8) of RC pumps in service, ingpm.

(2.50E+05 gpm/pump) x (# of RC pumps in service)

DF = required dilution factor to be applied to the undiluted effluent flow, unitless.

C DF=a x L (10 i

1 x EC)

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 McGuire Nuclear Station Offsite Dose Calculation Manual (ODCM)

Note:

If DF ~ 1.0 then no dilution is required and the release rate is unrestricted.

If DF > 1.0 then dilution flow is required and the allowable release rate is calculated using Equation 2.1. Equation 2.1 is used only when DF > 1.0.

cr = the recirculation factor at equilibrium at the RC discharge location, (dimensionless).

The recirculation factor accounts for the fraction of discharged water reused by the station. Equation reference: McGuire Final Environmental Statement, (10/1972) u = I + Qdf = I+ 3740 = 2.26 Qcf 2976 where:

QdJ ammal average RC dilution flow (3740 cfs). (1990-1994 average flow)

Qcf annual average flow past Cowans Ford Dam (2970 cfs). (1990-1994 average flow)

C, the concentration ofradionuclide, 'i', in the undiluted liquid effluent, in µCi/ml.

EC; the concentration ofradionuclide, 'i', from 10CFR20, Appendix B, Table 2, Column 2, in µCi/ml. Note: ifradionuclide, 'i', is a dissolved noble gas, then EC;= 2.00E-05 µCi/ml.

2.0.1.2 WC AND WWCB DISCHARGE Liquid releases to the Catawba River through the WC and WWCB discharge pathways normally contain measurable activity above background. The WC/WWCB effluent typically accounts for <l % of the station total liquid activity released. Although designed for continuous discharge, inputs to WC, primarily from the Unit 1 and Unit 2 turbine building sumps, are normally held up in one of two WC Settling Ponds, and then released as a batch. There is a composite sampler at the discharge to the river. An EMF monitors the TBS and Condenser Drain (WU) output (See Figure 2.0-3). It is assumed that no activity is present in the TBS/WU effluent until indicated by radiation monitoring measurements. If an EMF alarms, the TBS/WU pumps are secured. At this time the discharge may be routed to the floor drain tank for processing or routed directly to the condenser cooling water (RC) flow rather than to WC.

Releases going directly to the WWCB are in continuous release. Some activity is planned for release through this pathway during condenser draining; therefore, grab samples are collected and retained for composite generation. Similar to WC, the only radiation monitoring is on the TBS/WU output (see Figure 2.0-3).

WZ (groundwater) Sump C discharges to the Standby Nuclear Service Water Pond (SNSWP). To account for WZ activity discharged into the SNSWP a composite sampler is installed in WZ Sump C (see Figure 2.0-3).

The unit vents are the release points for waste gas decay tanks, containment building purges, auxiliary building ventilation, and the condenser air ejector (see Figure 2.0-4). Each unit vent contains multi-range radiation monitors (EMFs) and flow rate measuring instrumentation.

There are three other separate gaseous effluent release points at McGuire; the Waste Management Facility, Waste Handling Area and Unit 2 Staging Building. These three release points contribute a small percentage of the total site gaseous effluent. Each release point has an EMF, composite sampler, and flow totalizer (see Figure 2.0-5).

2.0.2.1 UNIT VENT DISCHARGE RELEASE RATE LIMIT CALCULATION In order to comply with Technical Specifications and Selected Licensee Commitments and to assure that the dose rate, at any time, at or beyond the site boundary due to radioactive materials released in gaseous effluents from the site is limited to:~ 500 mrem/yr to the total body, and ~ 3000 mrem/yr to the skin for the noble gases, and is limited to ~ 1500 mrem/yr to any organ for radioiodine and for radioactive materials in particulate form, and radionuclides other than noble gases with half lives greater than 8 days, the following release rate and radiation monitor setpoint calculations shall be performed for releases from the waste gas decay tanks and the containment building. The release rate calculations when solved for the flow rate, 'f, are the release rates for noble gases and for radioiodines, particulates and other radionuclides with half-lives greater than 8 days. The most conservative release rate calculated shall control the flow rate. The following equations are based on the site dose rate limits. For simultaneous releases a multiple release calculation is performed to ensure that the site dose rate limits are not exceeded.

• The location is the NNE sector at 0.5 mile. The boundary for establishing gaseous effluent release limits is the Exclusion Area Boundary (EAB). As shown in McGuire UFSAR Figure 2-5, the EAB is defined as a 2500 foot (-0.5 mile) radius from the station center.

W = the highest calculated annual average dispersion or deposition parameter for estimating the maximum dose rate to an individual from the total inhalation, food, and ground plane pathways:

By substituting the dilution factor (DF) from Equation 2.2 into Equation 2.1, solving for the undiluted liquid effluent concentration, Ci, and accounting for the monitor background reading, the liquid radiation monitor setpoint can be readily obtained by multiplying Ci by the radiation monitor correlation factor, CF i, as follows:

C (F + f)

~ ~~~~~~~~-

x (10 x EC) Equation 3.1 (J' X f SP ~ L (e, X CF;) + bkg Equation 3 .2 where:

C, the maximum allowable concentration of radionuclide, 'i', in the undiluted liquid effluent, in µCi/ml.

SP radiation monitor setpoint, in cpm.

CF; = radiation monitor correlation factor for radionuclide, 'i', in cpm/µCi/ml. These correlation factors are controlled by station procedures.

bkg = background reading for the radiation monitor, in cpm.

All other parameters were previously defined.

Using conservative or "worst-case" parameters in Equation 3.1 and Equation 3.2 can provide a liquid radiation monitor setpoint that does not need to be revised for every release if activity is low enough to allow for this type of operation such as with continuous releases from the WC release point. However, for batch releases, e.g., waste monitor tanks, through the RC discharge the radiation monitor setpoint is calculated based on actual expected activity in the release. In general, liquid radiation monitors are calibrated to Cs-137, and their setpoints are calculated as follows:

3.0.1.1 WASTE MONITOR TANK SETPOINTS (EMF 49)

As shown on Figure 2.0-2, EMF 49 is the controlling radiation monitor for Waste Monitor Tank (WMT) releases. EMF 49 setpoints are based on actual tank activity, and are calculated as follows:

Expected cpm = (Ccs - m x CFcs - 137) + bkg Trip 1 setpoint= (Ccs-m x CFcs-137 x 1.5) + bkg When Cs-137 equivalent concentration ~ l.43E-05 µCi/ml:

Trip 2 setpoint = (Ccs -137 x CFcs -137 x 2.0) + bkg or 3 x bkg, whichever is higher.

If the Cs-137 equivalent concentration is ~ l.43E-05 µCi/ml, then l.43E-05 is used in the Trip 1 and Trip 2 setpoint calculations. This is an indication of a low activity tank, and normal EMF fluctuation may cause Trip 2 alarms and release termination.

When Cs-137 equivalent concentration > l.43E-05 µCi/ml:

Trip 2 setpoint = (Ccs - /3 7 X CFcs - / 37 X 2. 0) + bkg where:

Note: when applied to the individual release points the 500 mrem/year site dose rate value is apportioned 40% to each unit vent, 7% to the Waste Handling Area, and 6.5% each to the Waste Management Facility and Unit 2 Staging Building.

Cxe-133 = the maximum allowable Xe-133 equivalent concentration in the gaseous effluent, in µCi/cc.

f = the gaseous effluent flow from the tank, building, or vent, in ft 3/min.

SP = radiation monitor setpoint, in cpm.

CF the Xe-133 equivalent monitor correlation factor, in cpm/µCi/cc. The correlation factors are controlled by station procedures.

bkg = the radiation monitor background reading, in cpm.

Equation 3 .6 provides the methodology to calculate the maximum setpoint for continuous releases. However, most gaseous releases at McGuire are batch releases, e.g.,

Containment Purge (VP), in which the radiation monitor setpoint is calculated based on actual activity expected in the release. For batch releases with a low activity release rate, e.g., Containment Air Release and Addition (VQ), the expected monitor response is essentially no greater than the existing reading, and the trip setpoints are based on multiples of the existing cpm or a maximum based on flow rate. For batch releases where the effluent can contain activity significantly above background, e.g., Waste Gas Decay Tank (WGDT), the following setpoint methodology is used:

CYe - 133 = L (c X Eq;)

As shown on Figure 2.0-4 and Figure 2.0-5, EMF 39 is the controlling radiation monitor for VP and IP releases from Containment to the Unit Vent.

For VP and IP low activity releases (i.e. Expected cpm ~ l .OE+04 cpm) only EMF 39 setpoints are calculated. EMF 39 setpoints for VP and IP low activity releases are calculated as follows:

Expected cpm = background = current reading Section 3 - Page 10 9-39

Trip 1 setpoint = any number between Expected cpm and Trip 2, normally 2 x Expected cpm Trip 2 setpoint = 2.9E+04 cpm, derived as follows:

SP = 8.20E-04 x 3.54E+07 = 2.9E+04 cpm Note: The flow rate used for VP is 2.31E+04 cfm, but the same setpoint would be used for IP. The IP flow rate is 800 cfm, therefore the 2.9E+04 cpm setpoint is conservative for IP.

For VP and IP high activity releases (i.e. Expected cpm > l .OE+04 cpm) it may be necessary to give the "affected" unit (the unit making the VP or IP release) a greater allowable release rate than the 200 mrem/yr default value. For the VP and IP high activity cases, in addition to EMF 39 setpoints, the EMF 36 Trip 2 setpoint is calculated as follows:

EMF 36 Expected CPM = VP x EMF 39 cpm x O. 75 (VP* + UV) where:

EMF 39 cpm = EMF 39 present or expected reading.

M = Multiplication factor for dose assignment to the affected unit vent. M can be~ 2 (= 200 mrem/yr), but, if> 2, both unit vents together must be ~ 4 (=400 mrem/yr). Note that increasing the Multiplication Factor is in effect giving the "affected" unit more of the station release rate limit, and decreasing the release rate limit for the "unaffected" unit.

VP* indicates that VP flow is not used in the denominator if VP is already running.

As shown on Figure 2.0-4 and Figure 2.0-5, EMF 50 (when operable) and EMF 36 (when EMF 50 is not operable) are the controlling radiation monitors for WGDT releases to the Unit Vent.

EMF 50 setpoints are based on actual tank activity, and are calculated as follows:

Expected cpm = (Cxe - 133 x CFxe - 133) + bkg Trip 1 setpoint = (Cxe -133 x CFxe -133 x 1.5) + bkg Trip 2 setpoint = (Cxe -133 x CFxe -133 x 3.0) + bkg where:

CFx e-133 = EMF 50 Xe-13 3 correlation factor, 1. 7SE+06 cpm/µCi/ml.

bkg = Background reading from EMF 50.

If the Xe-133 equivalent concentration is~ 5.71E-05 µCi/ml, then 5.71E-05 is used in the Trip 1 and Trip 2 setpoint calculations. This is an indication of a low activity tank, and normal EMF fluctuation may cause Trip 2 alarms and release termination.

The unit vent gas radiation monitor, EMF 36, is used as the controlling monitor for WGDT releases if EMF 50 is inoperable. In the rare occurrence that EMF 36 must be used as the controlling monitor for WGDT releases only the "expected" cpm is calculated, and the EMF counts are monitored manually during the WGDT release. The EMF 36 expected counts from WGDT activity is calculated as follows:

Dose contributions to the maximum individual shall be calculated at least every 31 days, quarterly, and annually using software which implements the ODCM methodology. The software is designed to automate many of the tasks required in the administration of effluent releases at McGuire and perfonns normal operation effluent dose assessment using NUREG-013 3 and Regulatory Guide 1.109 methodology.

Station long-tenn historical and dose projection calculations are performed periodically to determine the station's status with respect to meeting annual ALARA goals specified in the McGuire SLCs. Such calculations are used to verify that adequate margin remains during a report period to allow normal station and radwaste system operation, including anticipated operational occurrences, for the remainder of the report period without exceeding applicable goals. Station 31-day dose projections that are used to assess the need to reduce effluent releases with the Gaseous Waste (WG) or Liquid Waste (WL) systems as required in the McGuire SLCs are estimated by the previous month's calculated dose results.

Fuel cycle dose calculations shall be performed annually or as required by special reports.

Dose contributions shall be calculated using the software implementing the ODCM methodology.

4.0.1 LIQUID EFFLUENT DOSE MODEL FOR THE MAXIMUM EXPOSED INDIVIDUAL Of the possible exposure pathways in the aquatic environment, only three contribute significantly to the total dose; these pathways are ingestion of potable water and aquatic foods, and direct exposure from radioactivity deposited on the shoreline. The dose contribution from these pathways for measured quantities of radioactive materials identified in liquid effluents released to unrestricted areas shall be calculated for the maximum exposed individual in each age group using the methodology provided in this section.

There are two liquid discharge points to the environment at McGuire; (I) the Condenser Cooling Water System (RC) discharge point to Lake Norman, and (2) the Conventional Waste Water System (WC) and Waste Water Collection Basin (WWCB) discharge point to the Catawba River downstream of Cowan's Ford Dam (See Figure 2.0-1 ). Liquid dose calculations for the maximum exposed individual are performed and documented in the Annual Radioactive Effluent Release Report for both locations using the applicable activity release and dilution data for each liquid effluent release point. The primary Section 4 - Page 1 9-44

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 McGuire Nuclear Station Offsite Dose Calculation Manual (ODCM) liquid effluent discharge point for McGuire is through RC to Lake Norman. In general, only low activity tritium releases (<I% station total) occur through the WC and WWCB discharge point to the Catawba River. Dose calculations are performed for each of the two liquid discharge points for dose reporting purposes. The highest calculated dose from the two dose calculations is used to define the maximum individual dose from liquid releases at McGuire.

• The recirculation factor accounts for the fraction of discharged water reused by the station. The recirculation factors are based on methodology given in the McGuire Final Environmental Statement (10/1972), and historic annual average values based on 1990-1994 data. These values can be modified to account for deviations from average in a particular year for use in calculating maximum individual dose. A recirculation factor of 4.0 is currently being used for all pathways in the liquid dose calculation model for added conservatism.

• Maximum individual organ dose is determined by calculating the organ dose at each of the x!Q and D/Q locations shown in Table 6.0-8 and Table 6.0-9 (144 locations), and then choosing the maximum dose. Dose is calculated only for pathways ( e.g., garden, milk animal, etc.) that actually exist at each location as determined by the land use census. The boundary for establishing gaseous effluent release limits is the Exclusion Area Boundary (EAB). As shown in McGuire UFSAR Figure 2-5, the EAB is defined as a 2500 foot (-0.5 mile) radius from the station center.

• • C-14 airborne activity released to the environment is estimated based on actual power generation as discussed in Regulatory Guide 1.21, Revision 2. A value of 9.4 Ci/GWe-yr is used along with actual power generation to estimate C-14 activity released to the environment via gaseous effluents from McGuire. 9.4 Ci/GWe-yr is based on information from "Estimation of Carbon-14 in Nuclear Power Plant Gaseous EjJluents",

The point kernel method has been used to calculate offsite dose rates from radioactive materials stored in the refueling water storage tanks, reactor makeup water storage tanks, and temporary onsite radwaste storage tanks. Dose calculations using this method performed for McGuire Nuclear Station indicate direct radiation doses are much less than 0.01 mrem/yr and, therefore, make a negligible contribution to individual dose. Likewise, direct and air-scatter radiation dose contributions from the onsite Independent Spent Fuel Storage Installation (ISFSI) at McGuire have been calculated and documented in the McGuire 10CFR72 .212 evaluation report. The results of the calculation demonstrate that the annual dose to any "real individual" beyond the controlled area boundary is below the 10CFR72.I04(a) and 40CFR190.I0(a) limit of 25 mrem from direct and skyshine radiation, and all other fuel cycle sources (e.g., effluent). Direct radiation doses will not be calculated routinely.

4.0.4 EFFLUENT APPORTIONMENT For the McGuire Nuclear Station the effluent releases are apportioned equally to each unit for each site as recommended by Section 3.1 ofNUREG-0133 , because the shared radwaste treatment systems at each site make it impractical to accurately ascribe releases to a specific reactor unit. For Annual Radiological Effluent Release Report purposes effluent releases are summed for each unit, and the maximum individual dose to the public is reported as a site total.

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 McGuire Nuclear Station Offsite Dose Calculation Manual (ODCM) 5.0 FUEL CYCLE CALCULATIONS In accordance with the requirements of 40CFR190, the annual dose commitment to any member of the general public shall be calculated to assure that doses are limited to 25 millirems to the total body or any organ with the exception of the thyroid which is limited to 75 millirems. In accordance with the requirements of the Selected Licensee Commitments, the annual dose commitment shall also be calculated any time twice the specified quarterly dose limit of the Selected Licensee Commitments is exceeded; these annual dose commitments may not just be calculated for the calendar year.

The "Uranium fuel cycle" is defined in 40CFR Part l 90.02(b) as:

"Uranium fuel cycle means the operations of milling of uranium ore, chemical conversion of uranium, isotopic enrichment of uranium, fabrication of uranium fuel, generation of electricity by a light-water-cooled nuclear power plant using uranium fuel, and reprocessing of spent uranium fuel, to the extent that these directly support the production of electrical power for public use utilizing nuclear energy, but excludes mining operations, operations at waste disposal sites, transportation of any radioactive material in support of these operations, and the reuse of recovered non-uranium special nuclear and by-product materials from the cycle."

Based on this definition of the fuel cycle and the information in 10CFR5 l, Table S-3, and Wash-1248, the radiological impact of the following operations has been assessed for McGuire Nuclear Station:

5.0.1 MILLING No milling operations occur within fifty miles of the McGuire Nuclear Station.

5.0.2 CONVERSION No uranium hexafluoride production occurs within fifty miles of the McGuire Nuclear Station.

5.0.3 ENRICHMENT No uranium enrichment operations occur within fifty miles of the McGuire Nuclear Station.

5.0.4 FUEL FABRICATION No fuel fabrication operations occur within fifty miles of the McGuire Nuclear Station.

The increments of dose resulting from liquid and gaseous effluent releases will be calculated using the software implementing the ODCM methodology. The dose from direct radiation, skyshine, and radiation from the station storage facilities has been estimated using conservative assumptions (see Section 4.0.3).

In certain situations more than one nuclear power station site may contribute to the doses to be considered in making fuel cycle dose assessments in accordance with 40CFRI 90.

However, since the McGuire and Catawba nuclear stations are located approximately 30 miles apart the relative dose contribution from each site to the other is insignificant, and can be ignored in assessing compliance with 40CFRI90.

5.0.6 FUEL REPROCESSING No fuel reprocessing operations occur within fifty miles of the McGuire Nuclear Station.

5.0.7 40CFR190 TOTAL DOSE DETERMINATION To summarize, only dose increments from nuclear power production operations (Section 5 .0.5) need be considered in calculations to demonstrate compliance with the requirements of 40CFR 190. The fuel cycle dose assessments for McGuire Nuclear Station only include liquid and gaseous dose contributions from McGuire and dose from McGuire's ISFSI since no other uranium fuel cycle facility contributes significantly to McGuire's maximum exposed individual. For this dose assessment, the total body and maximum organ dose contributions to the maximum exposed individual from McGuire's liquid and gaseous effluents are estimated using the following calculations:

Dwb(T) = Dwb(l) + Dwb(g)

Dmo(T) = Dmo(l) + Dmo(g) where:

Dwh (T) = Total estimated fuel cycle whole body dose commitment resulting from the combined liquid and gaseous effluents of McGuire during the calendar year of interest, in mrem.

Dmo(J') = Total estimated fuel cycle maximum organ dose commitment resulting from the combined liquid and gaseous effluents of McGuire during the calendar year of interest, in mrem.

The land is predominantly rural non-farm with a small amount of land being used to support beef cattle and farming. Recreation in the area is confined mostly to the lake and shores of Lake Norman and Mountain Island reservoir. The McGuire site is in northwestern Mecklenburg County, North Carolina, 17 miles north-northwest of Charlotte, North Carolina. The site is bounded to the west by the Catawba River channel and to the north by 32,510 acre Lake Norman. Lake Norman is impounded by Duke Energy's Cowans Ford Dam Hydroelectric Station, which is located immediately west of the site and on the Catawba River channel. The tail water of Cowans Ford Dam is the upper limit of Mountain Island Reservoir. Mountain Island Dam is located 15 miles downstream from the site. Lookout Shoals Hydroelectric Station is at the upper reaches of Lake Nonnan. Marshall Steam Station is located on the western shore of Lake Nonnan, approximately 16 miles upstream from the site. The site exclusion radius is 2500 feet.

Table 6.0-1 and Table 6.0-2 define the sampling and TLD locations for the McGuire Radiological Monitoring Program. Figure 6.0-1 and Figure 6.0-2 illustrate these locations as compared to McGuire Nuclear Station.

This census satisfies the requirements of Section IV.B.3 of Appendix I to I0CFR50. The land use census identifies nearest pathways to the exclusion area boundary (EAB, - 0.5 mile) for each of the 16 meteorological sectors. Global Positioning System field measurements are taken as close as possible to the item of interest and are accurate to within 2-5 meters. Locations beyond the nearest pathway for each sector are assumed to contain that pathway for dose calculation purposes. For the 4.5-5.0 mile sector all pathways, i.e., residence, garden, milk animal (goat), and meat animal (cow), are assumed to exist for dose calculation purposes. Results are maintained on file and data reviewed in accordance with procedure AD-CP-ALL-0014, Land Use Census Evaluation.

The methodology is based upon Regulatory Guide 1.111, as implemented by the NRC's computer model "XOQDOQ: Computer Program for the Meteorological Evaluation of Routine Effluent Releases at Nuclear Power Stations," NUREG/CR-2919, PNL-4380, September 1982.

Five years of hourly meteorological data from the onsite instruments are processed into a representative joint frequency distribution of winds and atmospheric stability for input into the XOQDOQ model (Version 2.0). Thus, the air dispersion and deposition factors (x/Q and D/Q) output by the model are based on a five-year climatology for the site.

6.0.3.1 XOODOO METHODOLOGY AND ASSUMPTIONS A continuous, routine release (non-purge) is simulated from each unit vent. The release type is treated as "ground-level" in the model, for which surrounding terrain elevations are not input. The locale does consist of gently rolling terrain, so the default open terrain recirculation factor is applied in XOQDOQ [KOPT(8)=1]. This correction factor is recommended in RG 1.111 to adjust the straight-line airflow of the model for spatial and temporal variations that are produced by large scale weather patterns, or other non-linear flow conditions at local and regional scales.

In order for XOQDOQ to treat the plume as a ground-level release, the exit velocity and the inside diameter of the unit vent must be input as zero. The heat emission rate of each vent is also assumed to be zero, as recommended by the model. The height of the vent (40.2 m) above plant grade elevation (760 ft msl) is then used to determine the plume centerline height. Using the building height (43. l m) and minimum cross-sectional area of the containment building (1616 m2), XOQDOQ applies a building wake correction to the relative air concentrations from the ground level release.

Calculations of relative air concentrations and deposition are made for grid receptor distances per sector. The "no decay" assumption is used in the XOQDOQ model.

6.0.3.2 METEOROLOGICAL DATA Five years ( 1988-1992) of hourly, onsite meteorological data are used to produce the joint frequency distributions of wind speed and direction per stability class. The 10 m level winds are used. It is these joint frequency distributions which are input to the XOQDOQ model. Hours of calm winds are distributed by direction with the same frequency as the lowest "noncalm" wind speed class [KOPT(l )= 1]. Thus, wind speed classes are established so that the lowest wind speed class is the starting threshold of the anemometer (i.e. the "calm" wind speed class). The largest wind speed class has the upper bound of Section 6 - Page 9 9-76

(5 mis + max hourly wind speed). Stability classes (A-G) are based on the vertical temperature gradient, measured by the hourly averaged delta-T variable.

6.0.3.3 ANNUAL XOODOO COMPARISON TO THE ODCM Each year, the prevailing winds and stability class frequencies for MNS are compared to the 5-year period ( 1988-1992) upon which the xlQ and DIQ calculations have been made.

The 5-year climatology is summarized in Table 6.0-4 and Table 6.0-5 below. Since the comparison is being made to a 5-year climatology, significant differences should not occur in the meteorological variables of concern (i.e. winds and delta-T). The meteorological comparison serves to verify this assumption.

The joint frequency distributions of wind speed and direction versus atmospheric stability class are also determined from the annual data to provide input to the XOQDOQ model.

Modeled x!Q and D/Q values for the 0.5 mile Exclusion Area Boundary at MNS are compared to the maximum of the (1988-1992) x/Q and D/Q values from all sectors. If the newly calculated annual dispersion and deposition values do not result in a significant increase in the calculated offsite dose relative to the 10CFR50, Appendix I dose objectives then the 5-year xJQ and D/Q values used in the Annual Radiological Effluent Release Report (ARERR) are not revised. An increase in calculated offsite dose that is greater than five percent of the 10CFR50, Appendix I dose objectives would be considered significant enough to warrant a change in the xJQ and D/Q values used in the ARERR. If an increasing trend in the annual xJQ and D/Q values compared to the 5-year values is noted then a revised set of 5-year xJQ and D/Q values will be generated. These limiting values are listed in Table 6.0-6. The entire x!Q and D/Q list based on directional sector and distance is given in Table 6.0-8 and 6.0-9.

The McGuire 40 m tall meteorological tower was replaced with a new 60 m meteorological tower in August 1998 and relocated on site. The 60 m tower became operational at hour 0000 on September 1, 1998. Determination of atmospheric stability prior to this time uses the 30 m separation criteria shown in Table 6.0-7, while data after this time uses the 50 m separation criteria.

Comparison of concurrent data from both the 40 m and 60 m McGuire meteorological towers was made for a limited period of simultaneous operation (August 19 to September 10, 1998) prior to termination of the historical 40 m tower. Results were documented in the Corrective Action Program (NCR 01697913 or PIP M-98-1240).

The analysis indicated the 40m tower was subject to microscale terrain related impacts due to its location below the dam elevation, near plant buildings. The current 60 m tower location north McGuire has an open exposure and is more representative of regional meteorological conditions.

NOTES:

(1) The LLD is defined , for purposes of these commitments, as the smallest concentration of radioactive material in a sample that will yield a net count, above system background ,

that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.

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

LLD = (2. 71/ T) + 4.65Sb 6

E

• V

• 2.22 x 10

• Y

• exp (-AM)

Where :

LLD is the "a priori" lower limit of detection as defined above (as microCurie per unit mass or volume),

Sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute) ,

E is the counting efficiency (as counts per disintegration),

Vis the sample size (in units of mass or volume),

6 2.22 x 10 is the number of disintegrations per minute per microCurie, Y is the fractional radiochemical yield (when applicable),

'A. is the radioactive decay constant for the particular radionuclide, L\t is the elapsed time between midpoint of sample collection and time of counting (for plant effluents, not environmental samples), and T is the background and sample counting time in minutes.

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 an.§ posteriori (after the fact) limit for a particular measurement.

(2) 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.

(3) To be representative of the quantities and concentrations of radioactive materials in liquid effluents, samples shall be collected continuously or intermittently 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.

(4) A batch release is the discharge of liquid wastes of a discrete volume. Prior to sampling for analyses, each batch shall be isolated and thoroughly mixed to assure representative sampling.

(5) 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.

(6) 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. The LLD for Ce-144 is 5x10-6 microCi/ml. 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 be identified and reported in the Annual Radioactive Effluent Release Report.

(7) The principal gas gamma emitters for which the LLD specification applies are Xe-133 and Xe-135. These are the reference nuclides in Regulatory Guide 1.21.

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 Liquid Effluents - Concentration 16.11.1 BASES This commitment is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will be less than 10 times the effluent concentration levels specified in 10 CFR Part 20, Appendix B, Table 2, Column 2.

This limitation provides additional assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within: (1) the Section II.A design objectives of Appendix I, 10 CFR Part 50, to a MEMBER OF THE PUBLIC, and (2) the limits of 10 CFR Part 20.1301 to the population. The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the controlling radioisotope and its EC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2. This commitment applies to the release of liquid effluents from all reactors at the site.

The basic requirements for the Selected Licensee Commitments concerning effluents from nuclear power reactors are stated in 10CFR50.36a. These requirements indicate that compliance with effluent Selected Licensee Commitments will keep average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 10CFR20.106 (new 10CFR20.1301 ). These requirements further indicate that operational flexibility is allowed, compatible with considerations of health and safety, which may temporarily result in releases higher than such small percentages, but still within the limits specified in the old 10CFR20.106 which references Appendix B, Table II concentrations (MPCs). These referenced concentrations are specific values which relate to an annual dose of 500 mrem. It is further indicated in 10CFR50.36a that when using operational flexibility, best efforts shall be exerted to keep levels of radioactive materials in effluents as low as is reasonably achievable (ALARA) as set forth in 10CFR50, Appendix I.

As stated in the Introduction to Appendix B of the new 10CFR20, the effluent concentration (EC) limits given in Appendix B, Table 2, Column 2, are based on an annual dose of 50 mrem. Since a release concentration corresponding to a limiting dose rate of 500 mrem/year has been acceptable as a SLC limit for liquid effluents, which applies at all times as an assurance that the limits of 10CFR50, Appendix I are not likely to be exceeded, it should not be necessary to reduce this limit by a factor of 10.

Operational history at Catawba/McGuire/Oconee has demonstrated that the use of the concentration values associated with the old 10CFR20.106 as SLC limits has resulted in calculated maximum individual doses to members of the public that are small percentages of the limits of 10CFR50, Appendix I. Therefore, the use of concentration values which correspond to an annual dose of 500 mrem should not have a negative impact on the ability to continue to operate within the limits of 10CFR50 Appendix I and 40CFR 190.

Having sufficient operational flexibility is especially important in establishing a basis for effluent monitor setpoint calculations. As discussed above, the concentrations stated in the new 10CFR20, Appendix B, Table 2, Column 2, relate to a dose of 50 mrem in a year.

When applied on an instantaneous basis, this corresponds to a dose rate of 50 mrem/year.

This low value is impractical upon which to base effluent monitor setpoint calculations for many liquid effluent release situations when monitor background, monitor sensitivity, and monitor performance must be taken into account.

The multiplier of ten is proposed because the annual dose of 500 mrem, upon which the concentrations in the old 10CFR20, Appendix 8, Table II, Column 2 are based, is a factor of ten higher than the annual dose of 50 mrem, upon which the concentrations in the new 10CFR20, Appendix 8, Table 2, Column 2, are based. Compliance with the limits of the new 10CFR20.1301 will be demonstrated by operating within the limits of 10CFR50, Appendix I and 40CFR190.

The required detection capabilities for radioactive materials in liquid waste samples are tabulated in terms of the lower limits of detection (LLDs).

1. Minimum flow dilution is assured by an interlock which terminates waste liquid release if the number of RC pumps running falls below the number of pumps required for dilution. The required number of RC pumps for dilution is determined per station procedures.

2. Radioactivity Monitor (EMF) shall not be declared functional unless both the EMF and the associated EMF's Minimum Flow Device are rendered functional.

BASES 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 minimum flow devices for EMFs listed in Table 16.11.2-1 are required to provide assurance of representative sampling during actual or potential releases of liquid effluents. An interlock between the EMF's minimum flow device and its associated flow rate measurement device disables the remove alarm during non-release timeframes for the purpose of the control room black board annunciator criteria that disable expected alarms. An EMF flow rate measurement device measures total flow of the effluent while the EMF minimum flow device measures the sample flow rate through the EMF. The Alarm/Trip Setpoints of these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the Alarm/Trip will occur prior to exceeding the limits stated in SLC 16.11.1. The FUNCTIONALITY 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. The Turbine Building Sump to RC Discharge Flow Measurement and Sampler Devices are for monitoring only and do not alarm or have any controls that require a COT.

BASES This commitment is provided to implement the requirements of Sections II.A, Ill.A and IV.A of Appendix I, 10 CFR Part 50 . The commitment implements the guides set forth in Section II.A of Appendix I. The REMEDIAL 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 to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable." Also , for fresh water sites with drinking water supplies that 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 Part 141. These requirements are applicable only if the drinking water supply is taken from the river 3 miles downstream of the plant discharge.

The dose calculation methodology and parameters in the ODCM implement the requirements in Section Ill.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 a MEMBER OF THE PUBLIC 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 Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.113, "Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977.

Each batch to be transferred to the chemical treatment ponds is limited by:

L QJ < 6 .0 x 105 pCi I gm j (C 1 x10) µCi/ml BASES The inventory limits of the chemical treatment ponds (CTP) are based on limiting the consequences of an uncontrolled release of the pond inventory. The expression in SLC 16.11.5 assumes the pond inventory is uniformly mixed, that the pond is located in an uncontrolled area as defined in 10 CFR Part 20, and that the concentration limit in Note 4 to Appendix B of 10 CFR Part 20 applies.

The batch limits of slurry to the chemical treatment ponds assure that radioactive material in the slurry transferred to the CTP are "as low as is reasonably achievable" in accordance with 10 CFR Part 50.36a. The expression in SLC 16.11.5 assures no batch of slurry will be transferred to the CTP unless the sum-of the ratios of the activity of the radionuclides to their respective concentration limitation is less than the ratio of the 10 CFR Part 50, Appendix I, Section II.A, total body dose level to the instantaneous whole body dose rate limitation, or that:

For the design of filter/demineralizers using powder resin, the slurry wash volume and the weight of resin used per batch is fixed by the cell surface area, and the slurry volume to resin weight ratio is constant at 100 ml/gram of wet, drained resin with a moisture content of approximately 55 to 60% (bulk density of about 58 pounds per cubic feet).

Qj = concentration of radioactive materials in wet, drained slurry (powdex resin) for radionuclide "j", excluding tritium, dissolved or entrained noble gases, and radionuclides with less than an 8-day half-life. The analysis shall include at least Ce-144, Cs-134, Cs-137, Co-58 and Co-60, in picoCuries/gram . Estimates of the Sr-89 and Sr-90 batch concentration shall be included based on the most recent monthly composite analysis (within 3 months); and Ci = 10 CFR 20, Appendix B, Table 2, Column 2, concentration for single radionuclide "j", in microCuries/milliliter.

The batch limits provide assurance that activity input to the chemical treatment ponds will be minimized, and a means of identifying radioactive material in the inventory limitation of SLC 16.11.5.

The basic requirements for the Selected Licensee Commitments concerning effluents from nuclear power reactors are stated in 10CFR50.36a. These requirements indicate that compliance with effluent Selected Licensee Commitments will keep average annual releases of radioactive material in effluents to small percentages of the limits specified in the old 10CFR20.106 (new 10CFR20.1301 ). These requirements further indicate that operational flexibility is allowed, compatible with considerations of health and safety, which may temporarily result in releases higher than such small percentages, but still within the limits specified in the old 10CFR20.106 which references Appendix 8, Table II concentrations- (MPCs). These referenced concentrations are specific values which relate to an annual dose of 500 mrem. It is further indicated in 10CFR50.36a that when using operational flexibility, best efforts shall be exerted to keep levels of radioactive materials in effluents as low as is reasonably achievable (ALARA) as set forth in 10CFR50, Appendix I.

McGuire Units 1 and 2 16.11.5-3 Revision 0 9-216

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 -12/31/2017 Chemical Treatment Ponds 16.11.5 BASES (continued)

As stated in the Introduction to Appendix B of the new 10CFR20, the effluent concentration (EC) limits given in Appendix B, Table 2, Column 2, are based on an annual dose of 50 mrem. Since a release concentration corresponding to a limiting dose rate of 500 mrem/year has been acceptable as a SLC limit for liquid effluents, which applies at all times as an assurance that the limits of 10CFR50, Appendix I are not likely to be exceeded, it should not be necessary to reduce this limit by a factor of 10.

Operational history at Catawba/McGuire/Oconee has demonstrated that the use of the concentration values associated with the old 10CFR20.106 as SLC limits has resulted in calculated maximum individual doses to members of the public that are small percentages of the limits of 10CFR50, Appendix I. Therefore, the use of concentration values which correspond to an annual dose of 500 mrem should not have a negative impact on the ability to continue to operate within the limits of 10CFR50, Appendix I and 40CFR 190.

Having sufficient operational flexibility is especially important in establishing a basis for effluent monitor setpoint calculations. As discussed above, the concentrations stated in the new 10CFR20, Appendix B, Table 2, Column 2, relate to a dose of 50 mrem in a year.

When applied on an instantaneous basis, this corresponds to a dose rate of 50 mrem/year.

This low value is impractical upon which to base effluent monitor setpoint calculations for many liquid effluent release situations when monitor background, monitor sensitivity, and monitor performance must be taken into account.

Therefore, to accommodate operational flexibility needed for effluent releases, the limits associated with SLC 16.11.1 are based on ten times the concentrations stated in the new 10CFR20, Appendix B, Table 2, Column 2 to apply at all times. The multiplier of ten is proposed because the annual dose of 500 mrem, upon which the concentrations in the old 10CFR20, Appendix B, Table II, Column 2 are based, is a factor of ten higher than the annual dose of 50 mrem, upon which the concentrations in the new 10CFR20, Appendix B, Table 2, Column 2, are based. Compliance with the limits of the new 10CFR20.1301 will be demonstrated by operating within the limits of 10CFR50, Appendix I and 40CFR 190.

These referenced concentrations are specific values which relate to an annual dose of 500 mrem. It is further indicated in 10CFR50.36a that when using operational flexibility, best efforts shall be exerted to keep levels of radioactive materials in effluents as low as is reasonably achievable (ALARA) as set forth in 10CFR50, Appendix I.

As stated in the Introduction to Appendix B of the new 10CFR20, the effluent concentration (EC) limits given in Appendix B, Table 2, Column 1, are based on an annual dose of 50 mrem for isotopes for which inhalation or ingestion is limiting or 100 mrem for isotopes for which submersion (noble gases) is limiting. Since release concentrations corresponding to limiting dose rates of less than or equal to 500 mrem/year to the whole body, 3000 mrem/year to the skin from noble gases, and 1500 mrem/year to any organ from Iodine 131, Iodine 133, tritium and for all radionuclides in particulate form with half-lives greater than eight days at the site boundary has been acceptable as a SLC limit for gaseous effluents to assure that the limits of 10CFR50, Appendix I and 40CFR190 are not likely to be exceeded, it should not be necessary to restrict the operational flexibility by incorporating the EC value for isotopes based on ingestion/inhalation (50 mrem/year) or for isotopes with the EC based on submersion (100 mrem/year).

Having sufficient operational flexibility is especially important in establishing a basis for effluent monitor setpoint calculations. As discussed above, the concentrations stated in the new 10CFR20, Appendix B, Table 2, Column 1, relate to a dose of 50 or 100 mrem in a year. When applied on an instantaneous basis, this corresponds to a dose rate of either 50 or 100 mrem/year. These low values are impractical upon which to base effluent monitor setpoint calculations for many effluent release situations when monitor background, monitor sensitivity, and monitor performance must be taken into account. Therefore, to accommodate operational flexibility needed for effluent releases, the limits associated with SLC 16.11.6 will be maintained at the current dose rate limit for noble gases of 500 mrem/year to the whole body and 3000 mrem/year to the skin, for Iodine 131, Iodine 133, tritium and all radionuclides in particulate form with half-lives greater than eight days an instantaneous dose rate limit of 1500 mrem/year to any organ.

Compliance with the limits of the new 10CFR20.1301 will be demonstrated by operating within the limits of 10CFR50, Appendix I and 40CFR190. Operational history at Catawba/McGuire/Oconee has demonstrated that the use of the dose rate values listed above (i.e. 500 mrem/year, 3000 mrem/year and 1500 mrem/year) as SLC limits has resulted in calculated maximum individual doses to members of the public that are small percentages of the limits of 10CFR50, Appendix I and 40CFR 190.

The required detection capabilities for radioactive materials in gaseous waste samples are tabulated in terms of the lower limits of detection (LLDs).

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 Radioactive Gaseous Effluent Monitoring Instrumentation 16.11.7 BASES 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 instrumentation consists of monitoring and sampling instrumentation. Monitors provide continuous display of process parameters with appropriate alarms and trip setpoints established. Samplers collect a portion of the desired process for subsequent laboratory analysis, and do not have alarm/trip capability. Samplers and the analysis program provide a method to assure that long term effluent release quantities do not exceed the requirements of SLC 16.11.6.

Monitors provide assurance that instantaneous effluent releases do not exceed the requirements of SLC 16.11.6. The minimum flow devices for EMFs listed in Table 16.11. 7-1 are required to provide assurance of representative sampling during actual or potential releases of gaseous effluents. The flow rate monitor quantifies the total gaseous effluent (both non-radioactive and radioactive) released to the environment.

During routine sampling, instrumentation may be turned off for short periods of time (not to exceed 15 minutes) in order to meet analysis requirements of SLC 16.11.6. This is considered to be a normal function of the equipment. The Alarm/Trip Setpoints for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the Alarm/Trip will occur prior to exceeding the limits stated in SLC 16.11.6. The FUNCTIONALITY 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.

BASES This commitment is provided to implement the requirements-of Sections- 11.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 11.C of Appendix I.

The REMEDIAL 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 materials in gaseous effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable.

The ODCM calculational methods specified in the TESTING REQUIREMENTS implement the requirements in Section Ill.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 a MEMBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated.

The ODCM calculational methodology and parameters for calculating the doses due to the actual release rates of the subject materials are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.111, "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 specifications for lodine-131 and 133, tritium, and radionuclides in particulate form with half-lives greater than 8 days are dependent upon the existing radionuclide pathways to man, in the areas at and beyond the SITE BOUNDARY. The pathways that 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.

NOTE------------------------------------------------

T he installed Gaseous Radwaste Treatment System shall be demonstrated FUNCTIONAL by meeting SLC 16.11.6, 16.11.8 and16.11.9.

TEST FREQUENCY TR 16.11.10.1 Project gaseous release doses from each unit to areas 31 days at and beyond the SITE BOUNDARY, in accordance with the methodology and parameters in the ODCM, when gaseous systems are being released without being processed by its radwaste treatment system.

BASES The FUNCTIONALITY of the WASTE GAS HOLDUP 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 commitment implements the requirements of 19 CFR Part 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objectives given in Section 11. 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 Section 11.8 and 11.C of Appendix I, 10 CFR Part 50, for gaseous effluents.

This commitment applies at all times to the release of radioactive materials in gaseous effluents from each unit at the site. For units with shared Radwaste Treatment Systems, the gaseous effluents from the shared system are to be proportioned among the units sharing that system in accordance with NUREG-0133, Chapter 3.1.

The specification requires the preparation and submittal of a Special Report whenever the calculated doses from plant generated radioactive effluents and direct radiation exceed 25 mrem to the whole body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem. For sites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within twice the dose design objectives of 10 CFR Part 50, Appendix I, and if direct radiation doses from the units and outside storage tanks are kept small.

This Special Report, as defined in 10 CFR Part 20.2203(a)(4), shall include an analysis that estimates the radiation exposure (dose) to a MEMBER OF THE PUBLIC from uranium fuel cycle sources, including all effluent pathways and direct radiation, for the calendar year that includes the release(s) covered by this report. It shall also describe levels of radiation and concentrations of radioactive material involved, and the cause of the exposure levels or concentrations. The Special Report will describe a course of action that should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40 CFR Part 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 8 km must be considered.

If the dose to any MEMBER OF THE PUBLIC is estimated to exceed the requirements of 40 CFR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected} , in McGuire Units 1 and 2 16.11.12-2 Revision 67 9-247

The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in SLCs 16.11.1 and 16.11.6.

An individual is not considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM NOTES:

1. Specific parameters of distance and direction sector from the centerline of one reactor, and additional description where pertinent, shall be provided for each and every sample location in Table 16.11.13-1 in a table and figure(s) in the ODCM. Refer to NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants," October 1978, and to Radiological Assessment Branch Technical Position, Revision 1, November 1979. Deviations are permitted from the required sampling schedule if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunction, every effort shall be made to complete corrective action prior to the end of the next sampling period. All deviations from the sampling schedule shall be documented in the Annual Radiological Environmental Operating Report. It is recognized that, at times, it may not be possible or practical to continue to obtain samples of the media of choice at the most desired location or time. In these instances suitable alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made within 30 days in the Radiological Environmental Monitoring Program. In lieu of an Licensee Event Report, identify the cause of the unavailability of samples for that pathway and identify the new locations(s) for obtaining replacement samples in the next Annual Radioactive Effluent Release Report and also include in the report a revised figure(s) and table for the ODCM reflecting the new location(s).

2. One or more instruments, such as a pressurized ion chamber, for measuring and recording dose rate continuously may be used in place of, or in addition to, integrating dosimeters. For the purposes of this table, a thermoluminescent dosimeter (TLD) is considered to be one phosphor; two or more phosphors in a packet are considered as two or more dosimeters. Film badges shall not be used as dosimeters for measuring direct radiation. The forty stations is not an absolute number. The number of direct radiation monitoring stations may be reduced according to geographical limitations; e.g. ,

at an ocean site, some sections will be over water so that the number of dosimeters may be reduced accordingly. The frequency of analysis or readout for TLD systems will depend upon the characteristics of the specific system used and should be selected to obtain optimum dose information with minimal fading.

3. The purpose of this sample is to obtain background information. If it is not practical to establish control locations in accordance with the distance and wind direction criteria, other sites that provide valid background data may be substituted.

4. Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or more after sampling to allow for radon and thoron daughter decay. If gross beta activity in air particulate samples is greater than ten times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.

RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM NOTES (continued):

5. Gamma isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents from the facility.

6. The "upstream sample" shall be taken at a distance beyond significant influence of the discharge. The "downstream" sample shall be taken in an area beyond but near the mixing zone. "Upstream" samples in an estuary must be taken far enough upstream to be beyond the plant influence. Salt water shall be sampled only when the receiving water is utilized for recreational activities.

7. A composite sample is one in which the quantity (aliquot) of liquid sampled is proportional to the quantity of flowing liquid and in which the method of sampling employed results in a specimen that is representative of the liquid flow. In this program composite sample aliquots shall be collected at time intervals that are very short (e.g. ,

hourly) relative to the compositing period (e.g., monthly) in order to assure obtaining a representative sample.

8. Groundwater samples shall be taken when this source is tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties are suitable for contamination.

9. The dose shall be calculated for the maximum organ and age group, using the methodology and parameters in the ODCM.

10. If harvest occurs more than once a year, sampling shall be performed during each discrete harvest. If harvest occurs continuously, sampling shall be monthly. Attention shall be paid to including samples of tuberous and root food products.

MAXIMUM VALUES FOR THE LOWER LIMITS OF DETECTION (LLD)

NOTES:

1. The LLD is defined, for purposes of these commitments, as the smallest concentration of radioactive material in a sample that will yield a net count (above system background) that will be detected with 95% probability with 5% probability of falsely concluding that a blank observation represents a "real" signal.

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

• V

• 2.22

• Y

• exp(-M!)

Where:

LLD is the "a priori" lower limit of detection as defined above (as picoCurie per unit mass or volume),

sb is the standard deviation of the background counting rate or of the counting rate of a blank sample as appropriate (as counts per minute) ,

Eis the counting efficiency (as counts per disintegration),

Vis the sample size (in units of mass or volume},

2.22 is the number of disintegrations per minute per picoCurie, Y is the fractional radiochemical yield (when applicable),

').,, is the radioactive decay constant for the particular radionuclide, flt is the elapsed time between sample collection (or end of the sample collection period) and time of counting (for environmental samples, not plant effluent samples) , and Tis the background and sample counting time in minutes.

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 an 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, unavoidable small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable. In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report.

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 Radiological Environmental Monitoring Program 16.11.13 BASES The Radiological Environmental Monitoring Program is established to monitor the radiation and radionuclides in the environs of the plant. The program provides representative measurements of radioactivity in the highest potential exposure pathways, and verification of the accuracy of the effluent monitoring program and modeling of environmental exposure pathways. The program is contained in SLC 16.11.13 - 16.11.16 and conforms to the guidance of Appendix I to 10 CFR Part 50.

The program includes the following:

1. Monitoring, sampling, analysis, and reporting of radiation and radionuclides in the environment in accordance with the methodology and parameters in the ODCM,

2. A Land Use Census to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the monitoring program are made if required by the results of this census, and

3. Participation in an lnterlaboratory Comparison Program to ensure that independent checks on the precision and accuracy of the measurements of radioactive materials in environmental sample matrices are performed as part of the quality assurance program for environmental monitoring.

The portion of the Radiological Environmental Monitoring Program required by this commitment provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the station operation. This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 and 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 the modeling of the environmental exposure pathways. Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring. The initially specified monitoring program will be effective for at least the first 3 years of commercial operation. Following this period, program changes may be initiated based on operational experience.

The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLDs). The LLDs required by Table 16.11.13-3 are considered optimum 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 an a posteriori (after the fact) limit for a particular measurement.

With the level of radioactivity in an environmental sampling medium at a specified location exceeding the reporting levels of Table 16.11.13-3 when averaged over any calendar quarter, in lieu of a Licensee Event Report, prepare and submit to the Commission within 30 days a Special Report that defines the corrective actions to be McGuire Units 1 and 2 16.11.13-13 Revision 137 9-261

When more than one of the radionuclides in Table 16.11 .13-2 are detected in the sampling medium, this report shall be submitted if:

concentration (1} + concentration (2} + . . . ... ~ 1.0 limit level (1) limit level (2)

When radionuclides other than those in Table 16.11.13-2 are detected and are the result of plant effluents, this report shall be submitted if the potential annual dose to a MEMBER OF THE PUBLIC is equal to or greater than the calendar year limits of SLCs 16.11.6, 16.11.8 and 16.11.9. This report is not required if the measured level of radioactivity was not the result of plant effluents; however, in such an event, the condition shall be reported and described in the Annual Radiological Environmental Operating Report. The methodology and parameters used to estimate the potential annual dose to a MEMBER OF THE PUBLIC shall be indicated in this report.

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 - 12/31/2017 Land Use Census 16.11.14 BASES This commitment is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the Radiological Environmental Monitoring Program are made if required by the results of this census. The best information from the door-to-door survey, from aerial survey, or from 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 50 m2 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 made: (1) 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/m 2

Attachment 9 Summary of Changes to the Offsite Dose Calculation Manual McGuire Nuclear Station Units 1 & 2 Period 1/1/2017 -12/31/2017 Gas Storage Tanks 16.11.20 BASES This SLC considers postulated radioactive releases due to a waste gas system leak or failure, and limits the quantity of radioactivity in each pressurized gas storage tank in the WASTE GAS HOLDUP SYSTEM to assure that a release would be substantially below the dose guideline values of 10 CFR Part 100 for a postulated event.

Restricting the quantity of radioactivity contained in each gas storage tank provides assurance that in the event of an uncontrolled release of the tank's contents, the resulting total body exposure to a MEMBER OF THE PUBLIC at the nearest exclusion area boundary will not exceed 0.5 rem. This is consistent with Standard Review Plan 11.3, Branch Technical Position ETSB 11-5, "Postulated Radioactive Releases Due to a Waste Gas System Leak or Failure," in NUREG-0800, July 1981.
