-Rxl Effluent Series 1. Purpose The Harris Nuclear Plant (HNP) Emergency Action Level (EAL) Technical Bases Manual contains background information, event declaration thresholds, bases and references for the site specific EAL and Fission Product Barrier (FPB) values used to implement the Nuclear Energy Institute (NEI) 99-01 Rev. 6 EAL guidance methodology.

This calculation document provides additional technical detail specific to the derivation of the gaseous and liquid radiological effluent EAL values developed in accordance with the guidance in NEI 99-01 Rev. 6.Documentation of the assumptions, calculations and results are provided for the HNP site specific Rxl series EAL effluent monitor values associated the NEI 99-01 Rev 6 EALs listed below.* NEI EAL AU1.1 (gaseous and liquid)* NEI EAL AAI.1 (gaseous and liquid)* NEI EAL AS1.1 (gaseous)* NEI EAL AGI.1 (gaseous)EP-EALCALC-HNP-1401 Page 3 of 39 Rev 0 HNP EAL Technical Bases Calculations

-Rxl Effluent Series 2. DEVELOPMENT METHODOLOGY AND BASES 2.1. Threshold Limits 2.1.1. RU1.1 Liquid Threshold Limits Guidance Criteria The RU1 Initiating Condition (IC) addresses a release of gaseous or liquid radioactivity greater than 2 times the Offsite Dose Calculation Manual (ODCM) limits for 60 minutes or longer.HNP Bases The ODCM Sections 2.0 and 2.1 (with reference to ODCM Operational Requirement 3.11.1.1) limits for the concentration of radioactive liquid effluents released from the site to the unrestricted area are as follows:* 10 times the effluent concentration (EC) levels of 10CFR20, Appendix B, Table 2* 2.OE-04 pCi/ml for dissolved and entrained noble gases The RU 1.1 liquid effluent EAL threshold values will equate to 2 times the ODCM limit.2.1.2. RU1.1 Gaseous Threshold Limits Guidance Criteria The RU1 Initiating Condition (IC) addresses a release of gaseous or liquid radioactivity greater than 2 times the Offsite Dose Calculation Manual (ODCM) limits for 60 minutes or longer.HNP Bases The ODCM Section 3.1 (with reference to ODCM Operational Requirement 3.11.2.1)limits for the concentration of radioactive gaseous effluents at the site boundary are as follows: " Less than or equal to 500 mrem/yr to the whole body (Noble Gasses)" Less than or equal to 3000 mrem/yr to the skin (Noble Gasses)* Less than or equal to 1500 mrem/yr to any organ (1-131, 1-133, tritium, and particulate with half-lives greater than 8 days)Inhalation (internal organ) limits are not applicable for EAL threshold determination since the specified surveillance involves collection and analysis of composite samples. This after-the-fact assessment (individual uptake) could not be made in a timely manner conducive to accident classification.

The RU1.1 gaseous effluent EAL threshold values will equate to 2 times the ODCM limit for the lesser of the whole body or skin exposure pathways.EP-EALCALC-HNP-1401 Page 4 of 39 Rev 0 HNP EAL Technical Bases Calculations

-Rxl Effluent Series 2.1.3. RA1.1 Liquid Threshold Limits Guidance Criteria The RA1 Initiating Condition (IC) addresses a release of radioactivity resulting in offsite dose greater than 10 mrem TEDE or 50 mrem thyroid CDE.This is based on values at 1% of the EPA Protective Action Guides (PAGs).Per NEI 99-01, the effluent monitor readings should correspond to the above dose limits at the "site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.HNP Bases The liquid effluent limits are based on the water concentration values given in 10 CFR 20 Appendix B Table 2 Column 2 (see Section 2.1.1 above). The 10 CFR 20 values are equivalent to the radionuclide concentrations which, if ingested continuously over the course of a year, would produce a total effective dose equivalent of 0.05 rem (50 millirem).

The EPA PAGs are based on a TEDE dose from immersion, inhalation and deposition.

The 10 CFR 20 limits and the EPA limits do not represent the same type of exposure and thus cannot be compared on a one to one basis.Additionally, significant dilution assumptions are incorporated in determining ODCM ingestion limits for liquid releases such that obtaining a dose of 10 mrem in one hour would require a discharge concentration above the effluent monitor threshold (ingestion of radioactivity from a liquid release at the site boundary is not practical).

Thus, the site specific EALs will not contain the RA1.1 liquid effluent monitor threshold value that equates to 1% of the EPA PAG. However, EALs RA1.3 and RA1.4 will remain applicable for liquid effluent releases that exceed the threshold based upon sample and field survey results.2.1.4. RA1.1 Gaseous Threshold Limits Guidance Criteria The RA1 IC addresses a release of radioactivity resulting in offsite dose greater than 10 mrem TEDE or 50 mrem thyroid CDE.Per NEI 99-01, the effluent monitor readings are based on values at 1% of the EPA Protective Action Guides (PAGs) at the "site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.HNP Bases The gaseous effluent limits for RA1.1 are based on values that equate to an offsite dose greater than 10 mrem TEDE or 50 mrem CDE thyroid, which are 1% of the EPA PAGs.EP-EALCALC-HNP-1401 Page 5 of 39 Rev 0 HNP EAL Technical Bases Calculations

-Rxl Effluent Series 2.1.5. RSI.1 Gaseous Threshold Limits Guidance Criteria The RS1 IC addresses a release of radioactivity resulting in offsite dose greater than 100 mrem TEDE or 500 mrem thyroid CDE.This is based on values at 10% of the EPA Protective Action Guides (PAGs) at the "site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.HNP Bases The gaseous effluent limits for RSI.1 are based on values that equate to an offsite dose greater than 100 mrem TEDE or 500 mrem CDE thyroid, which are 10% of the EPA PAGs.2.1.6. RGI.1 Gaseous Threshold Limits Guidance Criteria The RG1 IC addresses a release of radioactivity resulting in offsite dose greater than 1,000 mrem TEDE or 5,000 mrem thyroid CDE.This is based on values at 100% of the EPA Protective Action Guides (PAGs) at the"site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.HNP Bases The gaseous effluent limits for RG1.1 are based on values that equate to an offsite dose greater than 1,000 mrem TEDE or 5,000 mrem CDE thyroid, which are 100% of the EPA PAGs.2.2. Effluent Release Points Note -All effluent release points assume a background reading of zero to conservatively account for all modes of operation applicable to the EALs.2.2.1. Liquid Release Points Guidance Criteria Per NEI 99-01, the RU1 IC addresses normally occurring continuous radioactivity releases from monitored gaseous or liquid effluent pathways (EAL #1) and planned batch releases from non-continuous release pathways (EAL #2).Per NEI 99-01, the RA1 IC includes events or conditions involving a radiological release, whether gaseous or liquid, monitored or un-monitored.

Classification based on effluent monitor readings assumes that a release path to the environment is established.

If the effluent flow past an effluent monitor is known to have stopped due to actions to isolate the release path, then the effluent monitor reading is no longer valid for classification purposes.EP-EALCALC-HNP-1401 Page 6 of 39 Rev 0 HNP EAL Technical Bases Calculations

-Rxl Effluent Series The "site-specific monitor list and threshold values" should be determined with consideration of the selection of the appropriate installed gaseous and liquid effluent monitors.HNP Bases There are seven liquid radwaste discharge points to the environment at HNP (ODCM 2.0 and Figures 2.1-1 through 2.1-3): 1. Treated Laundry and Hot Shower Tank (TL&HST) -REM-1WL-3540

2. Waste Evaporator Condensate Tank (WECT) -REM-IWL-3541

3. Waste Monitor Tank (WMT) -REM-1WL-3542

4. Normal Service Water (NSW) System -REM-3500A/B Per the ODCM, the NSW system has a low potential for radioactive effluent releases, thus the NSW pathway does not meet the NEI 99-01 criteria for use as an EAL threshold.

5. Turbine Building Floor Drains (TBFD) -REM-1 MD-3528 Per the ODCM, the TBFD effluent has a low probability of radioactive contamination, thus the TBFD pathway does not meet the NEI 99-01 criteria for use as an EAL threshold.

6. Outside Tank Area Drains (OTAD) -REM-1 MD-3530 Per the ODCM, the OTAD effluent has a low probability of radioactive contamination, thus the OTAD pathway does not meet the NEI 99-01 criteria for use as an EAL threshold.

7. Secondary Waste Sample Tank (SWST) -REM-1WL-3542 Per the ODCM, the SWST has a low potential for radioactive effluent releases, thus the SWST pathway does not meet the NEI 99-01 criteria for use as an EAL threshold.

Cooling tower blowdown minimum dilution flow rates range from 14,250 gpm to 3,800 gpm (ODCM Table 2.1-2). Minimum dilution flow for the EAL threshold values for the release pathways above is assumed to be 3800 gpm.EP-EALCALC-HNP-1401 Page 7 of 39 Rev 0 HNP EAL Technical Bases Calculations

-Rxi Effluent Series 2.2.2. Gaseous Release Points Guidance Criteria Per NEI 99-01, the RU1 IC addresses normally occurring continuous radioactivity releases from monitored gaseous or liquid effluent pathways (EAL #1) and planned batch releases from non-continuous release pathways (EAL #2).Per NEI 99-01, the RA1 IC includes events or conditions involving a radiological release, whether gaseous or liquid, monitored or un-monitored.

Classification based on effluent monitor readings assumes that a release path to the environment is established.

If the effluent flow past an effluent monitor is known to have stopped due to actions to isolate the release path, then the effluent monitor reading is no longer valid for classification purposes.Per NEI 99-01, the RS1 and RG1 ICs addresses monitored and un-monitored releases of gaseous radioactivity.

Classification based on effluent monitor readings assumes that a release path to the environment is established.

If the effluent flow past an effluent monitor is known to have stopped due to actions to isolate the release path, then the effluent monitor reading is no longer valid for classification purposes.The "site-specific monitor list and threshold values" should include the effluent monitors described in emergency plan and emergency dose assessment procedures.

HNP Bases There are four gaseous effluent release points to the environment at HNP (ODCM 3.0 and Figure 3.1): 1. Plant Vent Stack 1 -RM-21AV-3509-1SA

2. Turbine Building Vent Stack 3A -RM-1TV3536-1

3. Waste Processing Building Vent Stack 5 -RM-1WV-3546-1

4. Waste Processing Building Vent Stack 5A- RM-1WV-3547-1 ODOM Figure 3.1 illustrates the waste streams that can flow into the four gaseous effluent release points. Containment purge and vent during refueling and decay tank pathways are not considered because they are intermittent or mode restricted sources.The HNP vent flow rates, in cfm, for the gaseous EAL thresholds is based on the Maximum Effluent Design Flow Rates (ODOM Table 3-1-3).EP-EALCALC-HNP-1401 Page 8 of 39 Rev 0 HNP EAL Technical Bases Calculations

-Rxl Effluent Series 2.3. Source Term 2.3.1. RU1.1 Liquid Source Term Guidance Criteria NEI 99-01 does not provide specific guidance for AU1 liquid source term assumptions.

HNP Bases The source term used for liquid effluent releases is Cs-1 34. Cs-134 has been selected based on it being the lowest effluent concentration value for any detectable radionuclide not known to be absent from the liquid effluent (ODCM 2.1.1).2.3.2. RU1.1 Gaseous Source Term Guidance Criteria NEI 99-01 does not provide specific guidance for AU1 gaseous source term assumptions.

HNP Bases The gaseous source term used for the Plant Vent release is based upon the NUREG-1940 Table 1-6 noble gas fraction of activity available at shutdown for fleet standardization.

The RU1.1 gaseous source term used for the Turbine Building vent, Waste Process Building vent 5 and Waste Process Building vent 5A are based upon the averaged annual release concentration given in ODCM Table 3.1-1.The RU1.1 source term is based on an activity mix that is limited to gaseous isotopes whereby all activity is assumed to be monitored as it is discharged.

2.3.3. RAI.1, RS1.1 and RGI.1 Gaseous Source Terms Guidance Criteria NEI 99-01 specifies that the calculation of monitor readings will require use of an assumed release isotopic mix; the selected mix should be the same for ICs AA1, AS1 and AG 1.HNP Bases DEC utilizes a common plant vent RCS source term basis for fleet standardization.

The source term utilized in the URI dose model provides the relative fractions and is taken from NUREG-1940 (referenced from URI Requirements Specification Appendix A Section A.1) with the release path 'T' selected to model a LOCA type event with fuel clad damage.Containment Aux Bldg Norm Filter PlantVent Env RCS HUT < 2 hrs HUT < 2 hrs Working Sprays Off EP-EALCALC-HNP-1401 Page 9 of 39 Rev 0 HNP EAL Technical Bases Calculations

-Rxl Effluent Series The RA/S/G1.1 source term for the pathway from the Turbine Building is taken from NUREG-1940 (referenced from URI Requirements Specification Appendix A Section A.1) with the release path 'E' selected to model a SGTR type event with fuel clad damage.RCS S/G Turb Bldg Filter TB Vent Env Boiling HUT < 2 hrs Working T V The RA/S/G1.1 source term utilized in the URI dose model for the pathway from the Waste Gas Decay Tank via the Waste Process Building vents is taken from FSAR table 15.7.1-2 (referenced from URI Requirements Specification Appendix A Section A.1) with the release path 'T' selected to model a tank rupture event.WGT WPB WTWBWPB Vent 5 Env (Path T) HUT < 2 hrs WGT WPB WTWBWPB Vent 5A Env (Path U) HUT < 2 hrs No credit is taken for source term decay. The start of release time entered into URI is coincident with the time of reactor trip.2.4. Release Duration Guidance Criteria Per NEI 99-01, the effluent monitor readings for RA1.1, RS1.1 and RG1.1 gaseous EAL threshold values should correspond to a dose at the "site-specific dose receptor point" (consistent with the calculation methodology employed) for one hour of exposure.HNP Bases The effluent monitor readings for RA1.1, RS1.1 and RG1.1 gaseous EAL threshold values are calculated for a release duration of one hour.2.5. Meteorology Guidance Criteria The effluent monitor readings should correspond to the applicable dose limit at the "site-specific dose receptor point." The "site-specific dose receptor point" is the distance(s) and/or locations used by the licensee to distinguish between on-site and offsite doses.The selected distance(s) and/or locations should reflect the content of the emergency plan, and the procedural methodology used to determine offsite doses and protective action recommendations.

This is typically the boundary of the Owner Controlled Area.Monitor readings will be calculated using a set of assumed meteorological data or atmospheric dispersion factors; the data or factors selected for use should be the same for ICs AA1, AS1 and AGI.HNP Bases The site specific meteorology used for the calculation of monitor readings is based on selections and inputs for the URI dose assessment model as documented below.EP-EALCALC-HNP-1401 Page 10 of 39 Rev 0 HNP EAL Technical Bases Calculations

Subject:

Median Wind Speed and Stability Values at Duke Energy Nuclear Sites 1.0 Overview Data from the most recent full five years (2009-2013) was used to calculate the median wind speed (WS), vertical temperature gradient (Delta-T), and stability dass at each of the Duke Energy nuclear sites in the Carolinas.

Upper level winds were used at Brunswick.

All other sites use the lower level.Singular median values for WS, Delta-I, and stability dass from all wind direction sectors are given in Table 1. NEI 99-01 Rev. 6 does not provide any guidance on selection of default meteorological conditions." These median values are irrespective of season or time of day, so the difference between the median values and actual meteorological conditions could be large." Also note that the median Delta-T values are in normalized units of (deg C/100m), and would need to be converted to reflect actual sensor separation distance on a tower, if needed.Table 2.1 through Table 2.6 contains sector-specific median values of Wind Speed, Delta-T and Stability Class for each of the 16 directional sectors. This information provides more site-specific characteristics, similar to what would have been evaluated for the previous Rev. 4 of NEI-99-01 guidance.

In addition, the most frequent sector from which the wind is blowing at each site for the five year period is also indicated in these tables.Table I Median Values from Years 2009-2013 Median Median Delta- Stability WS (mph) T (C/lO0m)

The units may need to be converted if actual delta-T based on tower-specific separation distances are required.1 EP-EALCALC-HNP-1401 Page 20 of 39 Rev 0 Attachment I Median Wind Speed and Stability Values Memo i 2.0 Data The data presented represents the median of the entire five-year span at each site (Table 1). as well as the overall medians broken down by directional sector (Tables 2.1 -2.6). Each value represents the middle of the dataset, with 50% of values above the median, and 50Y. of values below the median.Data for the Legacy Duke Energy sites was obtained from the Duke's Environmental Monitoring"Ambient Administration" archive, which contains validated hourly meteorological data. Data for the Legacy Progress sites was obtained from hourly meteorological data files provided by the vendor (Murray and Trettel), and has undergone their data review/GA process. The five-year analysis results presented here were determined independently of previous studies, however comparison to the Annual Effluent reports (2013 MET) for all sites showed good agreement with the values presented in Table 1.The sector-specific median values (Tables 2.1 through 2.6) had not been investigated previously.

from North 3.0 Discussion and Conclusion The median wind speed data presented in Table I compared to Tables 2.1 through 2.6 indicates typically varying conditions, depending on the directional sectors at each site. The overall median wind speed at a site (3-6 mph) is in the middle of the wider range of the sector-specific medians (1-9 mph).The singular median values sometime match well with the sector-specific median conditions of the most frequent directional sector, but can also be entirely different from the median of the most frequent wind direction sector. These differences span from potentially lower wind speeds which would be conservative for dose (i.e. Brunswick), to potentially higher wind speeds which would be non-conservative for dose (i.e Catawba).* Thus, the median values of wind speed should only be used for dose assessment as a last resort, when actual meteorological data is not available, or dose calculation is for some reason impaired.The median Stability Class is generally neutral (class D), but varies between D and E (slightly more stable) in the sector-specific tables (Tables 2.1 through 2.6). These median values are typical of daytime conditions, with a thermally mixed boundary layer.* Thus, the median stability class should only be used when there is no concern about actual time of day, seasonal variances, or extreme weather events..5 EP-EALCALC-HNP-1401 Page 24 of 39 Rev 0 Attachment 2 RUI.1 Liquid Effluent EAL Calculations
