SECTION 3 METEOROLOGICAL DATA AND DISPERSION ESTIMATES 3-1 METEOROLOGY AND DISPERSION DATA Meteorological data have been collected at the PPL Susquehanna, LLC site since the early 1970s. At the present time, the meteorological system is based on a 300-foot high tower located approximately 1,000 feet to the southeast of the plant. Wind sensors are mounted at the 10m and 60m elevations on this tower. Vertical temperature differential is measured with redundant sensor pairs between the 10m and 60m levels. Sigma theta (the standard deviation of horizontal wind direction) is calculated from wind direction at both levels. Dew point and ambient temperature sensors are present at the 10m level. Precipitation is measured at ground level.A back-up meteorological tower was erected in 1982. It is a 10m tower providing alternate measurements of wind speed, wind direction, and sigma theta. A 10m downriver meteorological tower is also available.

This tower measures wind speed, wind direction, sigma theta, temperature and dew point.Meteorological data are transmitted to the plant Control Room, Technical Support Center, Emergency Operations Facility for emergency response availability, and ABSG Consulting, Inc. ABSG Consulting, Inc., located in Rockville, Maryland, provides meteorological consulting services to PPL Susquehanna, LLC.Regulatory Guide 1.23 (Safety Guide 23) requires at least 90% data recovery for meteorological instrumentation.

During 2012, all meteorological instrumentation met the 90% data recovery requirement.

Table 3-1 lists the percent valid data recovery values for the parameters monitored as part of the PPL Susquehanna Meteorological Monitoring Program.Dispersion modeling for effluents from normal operation is done using the MIDAS system XDCALC program, a straight-line Gaussian plume model designed to estimate average relative concentration.

The model was developed in accordance with Regulatory Guide 1.111. For periods when the wind speed is calm, the actual wind direction that last occurred is used.XDCALC and the XQINTR program that interpolates X/Q values to exact locations both use terrain correction factors to account for the temporal and spatial variations in the airflow in the region. A straight-line trajectory model assumes that a constant mean wind transports and diffuses effluents in the direction of airflow at the release point within the entire region of interest.

The terrain correction factors were taken from FSAR Table 2.3-128.Tables 3-2 and 3-3 provide the joint frequency distribution of wind speed and direction (as a function of delta temperature) at the 10 and 60 meter elevations of the primary meteorological tower. Table 3-4 lists no decay, undepleted X/Q values at various distances from the site. Table 3-5 lists 2.26 day decay, undepleted X/Q values at various distances from the site. Table 3-6 lists 8-day decay, depleted X/Q values at various distances from the site and Table 3-7 is a listing of D/Q (relative deposition) values at various distances from the site.3-2 TABLE 3-1 METEOROLOGICAL DATA RECOVERY FOR 2012 Parameter Percent Valid Data Recovery Wind Speed 10m -Primary (1) 99.8 Wind Speed 60m -Primary 99.8 Wind Speed 10m -Backup (2) 98.5 Wind Speed 10mi -Downriver (3) 99.9 Wind Direction lOin -Primary 99.8 Wind Direction 60m -Primary 99.8 Wind Direction 10m. -Backup 98.5 Wind Direction lOin -Downriver 99.7 Temperature 10mi -Primary 100.0 Dew Point 10m -Primary 100.0 Delta Temperature 60m -Primary 99.6 Sigma Theta 10m. -Primary 99.8 Sigma Theta 60m -Primary 99.8 Sigma Theta lOin -Backup 98.5 Sigma Theta 10mi -Downriver 99.7 Precipitation

Dose calculations using measured and calculated effluent activity levels, meteorological data from the current reporting period and average river flow dilution factors resulted in estimated doses to individuals at levels below 10 CFR 20 and 10 CFR 50, Appendix I limits. Direct radiation resulting from plant operation (reported in the 2012 Annual Radiological Environmental Operating Report) contributed a maximum of 7.21 E-1 mrem (measured at TLD Location 9S2 and based on an occupancy time by a member of the public of 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> per quarter) at the Protected Area Boundary south of the plant. Based on airborne effluent sample data, the maximum organ (including thyroid)/total body dose is 7.43E-2 mrem (CHILD, LUNG Table 4-4). The maximum organ/total body dose from all liquid effluent is 2.16E-3 mrem (ADULT, GILLI Table 4-2). Conservatively adding the maximum organ/total body dose from liquid and gaseous effluent and the maximum total body dose determined from direct radiation results in a dose of 7.97E-1 mrem, which is 3.2% of the 40CFR1 90 limit of 25 mrem to total body/organ (except thyroid) and 1.1% of the 40CFR190 limit of 75 mrem to the thyroid.Doses to a maximally exposed member of the public from waterborne effluents are calculated for fish ingestion and shoreline exposure at the plant outfall, and drinking water ingestion at Danville, PA. Site specific parameters used in the calculations for the Danville receiver, specific for actual average blowdown and river level for the entire year are shown in Table 4-1.TABLE 4-1 SITE-SPECIFIC PARAMETERS USED FOR RETDAS CALCULATIONS (DANVILLE RECEIVER)FOR 2012 PARAMETER ENTIRE YEAR Cooling Tower Blowdown (CFS) 25.4 Average Net River Level (ft.) 6.1 Dilution Factor at Danville(1) 315.9 Transit time to Danville (hr.)(') 29 (')From ODCM-QA-005, Att. E 4-2 Summaries of maximum individual doses resulting from airborne and waterborne radioactive effluent releases from each unit are given in Table 4-2. Meteorological data from Section 3 were used to calculate the dose from airborne effluents.

The Radioactive Effluent Release Report includes an assessment of the radiation dose from radioactive effluents to members of the public within the site boundary.Within the Site Boundary there are several areas frequented by members of the public. There are no significant exposure pathways from waterborne effluents in these areas. Doses from airborne effluent are calculated for members of the public for the following locations:

Riverlands Energy Information Center, the Towers Club, and residence with the maximum X/Q value; the garden, dairy and meat producing farm with the maximum D/Q value; and the site boundary with the maximum X/Q value. Summaries of the calculated maximum doses within the site boundary and selected locations beyond the site boundary resulting from airborne effluents are presented in Table 4-4. The above referenced locations are shown on Figure 4-1.In the area comprising the Riverlands recreation area, which surrounds the Energy Information Center, three pathways of radiation exposure can be identified:

plume, ground, and inhalation.

There are no significant exposure pathways from waterborne effluents in this area. There are approximately 100,000 visitors to the Riverlands/Energy Information Center complex each year. For dose calculations, it is assumed the visitor stays in the area for one hour. The calculated dose rate and collective dose for visitors to the Riverlands/Energy Information Center during 2012 are shown on Table 4-3.Use of the RETDAS code yields calculated doses for the Riverlands area for the report period. These doses assume an occupancy factor of 100% for a member of the public during 2012. These calculated dose values are shown on Table 4-4.In Regulatory Guide 1.21, Revision 2, "Measuring, Evaluating, and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste", the NRC has recommended that U.S. nuclear power plants evaluate whether Carbon-14 (C-14) is a "principal radionuclide", and if so, report the amount of C-14 released.Radioactive effluent releases of C-14 have not increased but the decline in releases of other radionuclides has resulted in C-14 possibly becoming more prominent, specifically in airborne effluents.

This regulatory guidance has led to an industry initiative to evaluate and report C-1 4 in the Annual Radioactive Effluent Release Report.Information for C-14 dose impact is included as supplemental information in this report. Reportable values for dose impact do not include C-14 contribution.

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.4-3 In December 2010 the Electric Power Research Institute (EPRI) published Report S 1021106, "Estimation of Carbon-14 in Nuclear Power Plant Gaseous Effluents", which provides conservative technical guidance to support the calculation of C-14 released in radioactive effluents.

In a BWR the majority of C-14 is generated in the reactor core by neutron activation of reactor coolant, specifically 1 7 0(n,a) 14C. Thus C-14 generation is directly proportional to reactor power. As documented in the EPRI report (for a BWR), approximately 99% of the C-14 produced in the reactor core is discharged as gaseous effluent (primarily as C02) through the offgas system. The remaining 1% is released in the form of solid radwaste.

There is minimal (<1%) C-14 released in the liquid effluent pathway.In October of 2012 PPL Susquehanna, in conjunction with an offsite lab, performed sampling and analysis for airborne effluent C-14 released from the station via each units offgas system.Since both Susquehanna units are essentially identical in reactor design, a single value for the C-14 release rate (in the C02 form from the offgas system sample results) is used in the calculation of C-14 released from each unit. The release rate value is corrected to 100% power then scaled to the fraction of full power year for each unit. The fraction of a full power year is calculated as the Effective Full Power Days for the year in question divided by 365 to get the fraction of effective vs full year operation.

Based on the above outlined methodology, approximately 38 Curies of C-14 were released in gaseous effluents in 2012.The airborne effluent pathway with the highest offsite dose potential (for C-14 releases) is the vegetation ingestion pathway. The maximum expected annual dose from C-14 released from Susquehanna Unit-1 (3.OOE-1 mrem) and Unit-2 (3.57E-1 mrem) has been calculated based on methodology in Regulatory Guide 1.109 and includes site specific parameters (e.g., nearest garden with highest X/Q value, producing both broad leaf and non-broad leaf vegetation).

The maximum organ dose from airbome effluent C-14 released from the Susquehanna station in 2012 is well below the 10CFR50, Appendix I, ALARA design objective (i.e., 15 mrem/yr per unit). The annual dose to the maximally exposed individual from all gaseous releases of C-14 (calculated by the above referenced methodology) is 6.57E-1 mrem to the critical organ (bone) and 1.31 E-1 mrem to the total body.Conservatively adding the maximum dose (calculated based on liquid and gaseous effluent sample results combined with direct radiation results) referenced on page 4-2 to the maximum dose due to the calculated release of C-14 (6.57E-1 mrem, CHILD, BONE) bounds the dose that any member of the public receives from station operations to 1.45 mrem, which is 6% of the 40CFR1 90 limit of 25 mrem to total body/organ (except thyroid) and 2% of the 40CFR190 limit of 75 mrem to the thyroid. db 4-4 TABLE 4-2

8. FSAR Section 11.6.11 requires the reporting of airborne radioactivity detected in the Low Level Radwaste Holding Facility.Only naturally occurring airborne radioactivity was detected above analysis MDC's in air samples from the Low Level Radwaste Holding Facility during 2012.9. The PPL Susquehanna station has implemented an Action Plan in response to the NEI Initiative on Groundwater Protection.

Part of the Action Plan includes the assessment of the current groundwater monitoring program.Groundwater is sampled and analyzed quarterly as part of the Radiological Environmental Monitoring Program (REMP). REMP groundwater sampling locations are defined in ODCM-QA-008 Attachment G. In August 2006, additional groundwater sampling was initiated at locations which are not listed in the ODCM. The additional locations are three manholes which collect water from a perimeter drain system. The perimeter drain system consists of perforated piping installed just above the footing along the exterior base of the vertical walls of the reactor, turbine and radwaste buildings.

Outlined in Table 6-1 are the tritium analysis results from sampling of the perimeter drain system. No nuclear by-product gamma emitting radionuclides were identified above analysis MDC's for the perimeter drain samples in 2012. The tritium results reported in Table 6-1 did not exceed any Reporting Level thresholds in the PPL Susquehanna Technical Requirements Manual or any reporting criteria established in response to the NEI Groundwater Protection Initiative.

The CSTs and RWST are sampled monthly to determine the concentration of radionuclides present in these tanks. Tritium analysis on these samples is performed quarterly.

Airborne release to the environment from the tanks is estimated based on conservative estimates of the evaporation rates from each of the tanks using a modified method established within Chapter 7 of EPA AP-42. A conservative carry-over fraction of radionuclides from the water to the evaporated liquid is then assumed. Airborne release to the environment from the demisters conservatively assumes the maximum moisture (condensate) concentration of the lubrication oil as measured via sampling during 2012. The calculation also assumes immediate removal of 100% of the water by the oil mist eliminators as it passes through the turbines.The annual release of tritium, iodines and particulates with half-lives greater than 8 days was calculated based on the conservative assumptions outlined above. The 0 calculated releases are shown in Table 8-1. All nuclides, except for tritium, released from insignificant effluent pathways are negligible compared to the airborne release data shown in Tables 2-1 and 2-2. The maximum dose to the public from a release of 2.89 Ci of tritium is calculated to be 8.37E-3 mrem (child). This is a small fraction of the maximum dose from airborne effluent reported in Section 4.0 8-2 TABLE 8-1 ANNUAL RELEASE FROM SYSTEMS CLASSIFIED AS INSIGNIFICANT EFFLUENT PATHWAYS U1-CST and U2-CST and Main Turbine/RFPT Main Turbine/RFPT Nuclide RWST Lube Oil Systems Lube Oil Systems Total (Ci) (Ci) (Ci) (Ci)H-3 3.97E-02 1.37E+00 1.48E+00 2.89E+00 Mn-54 3.42E-09 4.35E-06 3.38E-08 4.39E-06 Co-60 1.68E-08 1.37E-05 9.60E-08 1.38E-05 Co-58 8.47E-10 7.92E-06 4.24E-08 7.96E-06 Zn-65 6.12E-10 7.07E-07 4.20E-09 7.12E-07 Xe-135 O.OOE+00 O.OOE+00 9.51E-11 9.51E-11 8-3
