SUMMARY

AND SUPPLEMENTAL INFORMATION 1-1 INTRODUCTION The submittal of the 2011 Radioactive Effluent Release Report is in accordance with PPL Susquehanna, LLC Tech Spec. 5.6.3. The enclosed information is consistent with the objectives outlined in the Offsite Dose Calculation Manual (ODCM) and Process Control Program (PCP). The 2011 Radioactive Effluent Release Report is in conformance with 10CFR50.36a and 10CFR50, Appendix I, Section IV.B.1.PPL Susquehanna, LLC is located in Salem Township, Luzerne County, Pennsylvania.

It is on the west bank of the Susquehanna River, 8 km northeast of Berwick. The station consists of two boiling water reactor generating units. Each unit has completed an Extended Power Uprate process which has increased licensed thermal power from 3489 MWt (megawatt thermal) to 3952 MWt. Unit-1 completed the power uprate in 2010 and Unit 2 completed the power uprate in 2011. The reactor and generating units were supplied by General Electric, while the Bechtel Corporation served as architect-engineer and constructor.

Construction of the Station began in the early 1970s. Fuel load began in Unit 1 in July of 1982. Initial criticality was achieved in the Unit 1 reactor on September 10, 1982.The reactor reached 100% power for the first time on February 4, 1983. Commercial operation of Unit 1 was declared on June 8, 1983. Initial criticality of Unit 2 occurred on May 8, 1984. Unit 2 was declared commercial on February 12, 1985.Airborne effluents are released from the Station via five rooftop vents on the reactor building (see Figure 1-1). Continuous sampling for particulates and iodines is performed at each vent as well as continuous monitoring for noble gases. A program of periodic sampling and analysis for tritium and noble gases along with periodic analysis of particulate and iodine samples is conducted as specified in the plant Technical Requirements.

All waterborne effluents are released in batch mode and are sampled and analyzed prior to release. Waterborne effluents from the site are released into the cooling tower blowdown line for dilution prior to release to the Susquehanna River (see Figure 1-2). Blowdown line flow rates are at least 5,000 gpm during periods of liquid radwaste release. The diluted effluent is introduced to the river by way of a perforated diffuser pipe placed on the river bed. The diffuser serves to mix the station discharge with the main flow of the river.This report presents a summary of the quantities of radioactive materials which were released from the Station during the period from January 1, 2011 to December 31, 2011. In addition, this report serves as a medium for notifying the US Nuclear Regulatory Commission staff of changes to the ODCM, PCP and documentation of any exceptions to the effluent monitoring program which must be reported per Technical Requirements.

Airborne and waterborne radioactive effluent releases to the environment during the report period were sampled and analyzed in accordance with the Technical 1-2 Requirements.

All radioactive effluent releases were within the concentration and release limits specified in the Technical Requirements.

Calculations and terms utilized in this report are those outlined in the ODCM.Section 1 contains supplemental information pertaining to effluents from the Susquehanna plant. Included are regulatory limits (Table 1-1), sampling and analysis methods, characterization of the number and duration of batch and abnormal releases and a brief summary of the applicable year's effluents.

Section 2 contains effluent and waste disposal data for the report period. Table 2-1 contains a summation of all airborne releases, grouped into the radionuclide categories of gases, particulates, iodines, and tritium. Average release rates are presented and compared to the applicable limits. Table 2-2 presents the activity totals of specific radionuclides in airborne effluents.

Waterborne effluents are summarized in Table 2-3. Average diluted concentrations are presented and compared to the applicable limits. Table 2-4 presents the release quantities of specific radionuclides in waterborne effluents over the report period.Figures 2-1 and 2-2 present the Susquehanna River Monthly Average Flow Rates for 2011 and the Monthly Liquid Radwaste Discharge Totals for 2011, respectively.

Table 2-5 contains estimates of the errors associated with the measurements involved in quantifying effluents.

Sampling errors, counting errors, and errors associated with determining effluent flow rates and volumes all contribute to the total error of effluent measurements.

Error estimates are presented for each category of radionuclide detected in airborne and waterborne effluents and solid wastes during the report period (Error Analysis of the Radioactive Effluent Sampling and Analysis Program at the SSES, Hydro Nuclear Services; 1985).Tables 2-7 through 2-15 present a characterization of the solid radioactive waste shipped offsite during the report period. An estimate of major nuclide composition is presented for each waste type. Also included are the volumes and curie contents associated with each type of solid waste. The number of waste shipments from the site transported directly for burial or disposal are listed in Table 2-6.Section 3 presents meteorological data for 2011, including data recovery, joint frequency distribution of wind speed and direction, stability class distribution, and atmospheric dispersion estimates for selected locations.

Section 4 of this report contains an assessment of the calculated doses attributed to the reported radiological effluents for the calendar year. The Radioactive Effluent Tracking and Dose Assessment Software (RETDAS) computer code was used for calculation of doses from waterborne effluents.

Site-specific parameters used in the calculations for the Danville receiver are shown in Table 4-1. The RETDAS code was also used for calculation of doses from airborne effluents.

The calculated doses and direct radiation estimates can be used to estimate the doses to maximally exposed members of the 1-3 public. Table 4-2 summarizes maximum calculated doses to members of the public from airborne and waterborne effluents.

Table 4-3 presents calculated collective doses to members of the public within the Riverlands/Energy Information Center Complex.Table 4-4 summarizes the calculated doses for residences and other occupied areas within the site boundary and the nearest dairy. Additionally, Section 4 includes a description of the methodology used in the calculation and resultant dose impact of carbon-14 released from the station.Section 5 of this report documents changes to the Offsite Dose Calculation Manual, Technical Requirements Manual and the Solid Radioactive Waste Process Control Program.Section 6 presents a listing of cases (if any) in which airborne or waterborne effluent monitoring instrumentation was declared inoperable and was not restored to operability within the time period specified in Technical Requirements 3.11.1.4, 3.11.1.5 and 3.11.2.6 Action Statements.

In addition, this section presents issues (if any) with the collection of milk or fresh leafy vegetables per Technical Requirement 3.11.4.1 and changes due to the land use census per Technical Requirement 3.11.4.2.

Section 6 also includes reporting associated with the Nuclear Energy Institute (NEI) Groundwater Protection Initiative.

Section 7 contains corrections (if any) to previous Radioactive Effluent Release Reports.Section 8 contains information on effluent and offsite dose from the systems classified as insignificant effluent pathways.1-4

SUMMARY

During 2011 there were one hundred forty eight (148) liquid batch releases resulting in a total release volume of one million four hundred eighty eight thousand (1,488,000) gallons. The total number of liquid batch releases and total volume released in 2011 was lower than the corresponding values for 2010 (206 releases resulting in 2,702,000 gallons released in 2010) due to the Unit-1 condenser area flood event (900,000 gallons of water discharged in addition to water released through liquid radwaste treatment system) which occurred in 2010. The predominant radionuclide released in liquid effluents during 2011 was tritium. Approximately fifty-two (52) curies of tritium were released in liquid effluents in 2011, compared to fifty seven (57) curies released in 2010. When compared with all radionuclides released in liquid effluents in 2011, Co-60 and Zn-65 were the main contributors to the resultant offsite dose. Consistent with previous years, the offsite dose from liquid releases in 2011 was less than one percent (1%) of the annual limits for both organ and whole body dose.In 2010, an industry initiative (supported by EPRI and NEI) was established to evaluate and report Carbon-14 (0-14) in the Annual Radioactive Effluent Release Report. The initiative is rooted in Regulatory Guide 1.21, Revision 2, "Measuring, Evaluating, and Reporting Radioactive Material in Liquid and Gaseous Effluents and Solid Waste", in that the NRC has recommended that U.S. nuclear power plants evaluate whether C-14 is a "principal radionuclide", and if so, report the amount of C-14 released.

The C-14 released from the Susquehanna station in 2011 was calculated using conservative guidance provided by the Electric Power Research Institute (EPRI Report No.1021106).

Based on the EPRI methodology, approximately 23 Curies of C-14 were released in gaseous effluents in 2011. See section 4 for additional details on the calculation of C-14 released in airborne effluents.

Historically, tritium has been the predominant radionuclide (both in Curies and resultant offsite dose) released in gaseous effluents from the Susquehanna station. Approximately forty-seven (47)curies of tritium were released in gaseous effluents in 2011 compared to thirty-one (31)curies in 2010. The resultant maximum offsite organ dose due to gaseous effluents from Unit-1 for 2011 was 4.56E-1 mrem, which is three (3%) of the per unit annual limit of fifteen (15) mrem. The resultant maximum offsite organ dose due to gaseous effluents from Unit-2 for 2011 was 3.34E-1 mrem, which is two percent (2%) of the per unit annual limit of fifteen (15) mrem. The maximum offsite dose from gaseous effluents was lower in 2011 when compared with 2010 due to the dose from C-14 releases being lower.1-5 FIGURE 1-1 AIRBORNE EFFLUENT RELEASE POINTS B JtNJ i EATOR UILDING MHUST VENT UNIT 2 REACTOR OLqLDDING EXHAUST VENT Ii h 1-6 FIGURE 1-2 WATERBORNE EFFLUENT PATHWAY FROM EVAPORATOR HEATING STEAM CONDENSATE RETURN TANK FROM PHASE SEPARATORS (DECANT)FROM RHR SYSTEM (SUPPRESSION POOL TRANSFERS)

1. Regulatory Limits Technical Requirements 3.11.1 and 3.11.2 outline requirements for release of radioactive liquid and gaseous effluents, respectively.

Concentration of radioactive materials released in liquid effluents and resulting dose are limited in unrestricted areas. Dose and dose rate due to radioactive materials released in gaseous effluents are limited in areas at or beyond the site boundary.

Technical Requirement limits are listed in Table 1-1.2. Maximum Permissible Concentrations in Waterborne Effluents The concentration of radioactive material released in liquid effluents to unrestricted areas is limited to 10 times the concentrations specified in 10 CFR Part 20 Appendix B Table 2, Column 2, for radionuclides other than dissolved or entrained noble gases.For dissolved or entrained noble gases, the concentration is limited to 2.OE-04 pCi/ml total activity (TRO 3.11.1.1).

3. Average Energv of Fission and Activation Gas The Calculation of Noble Gas Effluent Average Energies E-Bar Beta and Gamma was not performed due to the fact that no noble gases were measured in Station Vent Air Samples above detection limits during 2011.4. Measurements and Approximations of Total Radioactivity Analyses of specific radionuclides in effluent samples are used to evaluate the radioactive composition and concentration of effluents.

5. Methods of Quantifying Effluents a. Fission and Activation Gases: Gas samples are routinely collected monthly and analyzed with a high resolution (HPGE) detector system which incorporates a data reduction program to determine radionuclide composition in terms of specific activity.

Data from the continuous vent monitors are used to determine the average concentration of noble gases. The high resolution (HPGE) isotopic scan is used to convert the continuous vent monitor activity to actual activity based on the determined nuclide mixture. The vent and sample flow rates are continuously monitored and the average flow rates for each vent are used to calculate the total activity released in a given time period. When the continuous monitors are out of service, manual grab samples are taken from each vent once every eight hours (once every four 1-8 hours for the standby gas treatment vent when standby gas treatment system is in service).b. lodines: Iodine is continuously collected on charcoal or silver zeolite cartridges via an isokinetic sampling assembly in each vent. Filters are normally exchanged once per week and analyzed on a high resolution (HPGE) system. The daily average flow rates for the vents and sample pumps are averaged for the duration of the sampling period and a ratio of vent flow rate to sample flow rate is determined.

The ratio is used to determine the total activity of each isotope released during the time period in question.

When the continuous samplers are out of service, iodine is continuously collected from alternate sampling ports available on the sample lines or directly from the affected rooftop vent(s).c. Particulates:

Particulates are continuously collected via an isokinetic sampling assembly in each vent. Filters are normally exchanged once per week and analyzed on a high resolution (HPGE) system. Flow rate corrections are performed as for iodines. When the continuous samplers are out of service, particulates are continuously collected from alternate sampling ports available on the sample lines or directly from the affected rooftop vent(s).d. Tritium: Airborne tritium is collected monthly via bubbler sampler. The sample is collected for one hour at a flow rate of approximately 1000 cc/min.Tritium activity in the bubbler sample is determined by liquid scintillation counting.

The liquid sample tritium concentration is then converted to air concentration by volume proportion.

e. Waterborne Effluents:

Each tank of liquid radwaste is sampled and analyzed for principal gamma emitters prior to release. Each sample tank is recirculated for a sufficient amount of time prior to sampling to ensure that a representative sample is obtained.

Samples are analyzed on a high resolution (HPGE) system and release permits are generated based on the values obtained from the isotopic analysis and the most recent values for tritium, gross alpha, iron-55, and strontium-89 and -90. An aliquot based on release volume is saved and added to monthly and quarterly composite containers.

The monthly tritium analysis is done in-house.

A monthly composite is sent to a vendor laboratory for gross alpha analysis.

A quarterly composite is sent to a vendor laboratory for iron-55, strontium-89 and-90 analyses.The concentration of each radionuclide in each batch is multiplied by the volume of the batch to determine the total quantity of each nuclide released in each batch. The isotopic totals for each batch are summed to determine the total source term for the report period. 9 TABLE 1-1 TECHNICAL REQUIREMENT LIMITS A. NOBLE GASES: 1. 500 mrem/year

The lower limit of 1.OOE+06 pCi/min (1.67E+04 pCi/sec) based on total body dose rate is used.Iodine-1 31 A derived release rate limit for 1-131 based on the Technical Requirement (TRO 3.11.2.1.11.A) limit of 1500 mrem/yr from 1-131, 1-133, tritium and particulates with half-lives greater than 8 days was calculated (PPL calculation EC-ENVR-1041 Rev. 2) based on the ratio of the expected annual release quantities of 1-131 and 1-133 provided in Attachment E of ODCM-QA-004, Airborne Effluent Dose Calculations.

The limit is 1.04E+02 i.Ci/min I-131 (1.73E+00 pCi/sec).Particulates A derived release rate limit for particulate activity other than iodines based on the Technical Requirement (TRO 3.11.2.1.11.A) limit of 1500 mrem/yr from I-131, 1-133, tritium and particulates with half-lives greater than 8 days was calculated (PPL calculation EC-ENVR-1 041 Rev. 2) based on the expected annual release quanities of particulate radionuclides provided in Attachment E of ODCM-QA-004, Airborne Effluent Dose Calculations.

The limit is 3.02E+03 pCi/min (5.03E+01 VCi/sec).1-11 Tritium A derived release rate was calculated based on the 10 CFR 20, Appendix B, Table 2, Column 1, Effluent Concentration Limit for tritium (1.OE-07 pCi/cc) to unrestricted areas. A relative concentration of 4.1 E-05 sec/mi 3 was assumed (PPL calculation EC-ENVR-1 040). The limit is 1.46E+05 pCi/min (2.44E+03 pCi/sec).Radionuclide Fractional Summation The sum of the percents of applicable limits for particulates, iodine and tritium must be less than 100%.E. WATERBORNE EFFLUENT:

BASES FOR PERCENT OF APPLICABLE LIMIT VALUES IN TABLE 2-3 Fission and Activation Products Concentrations of fission and activation products in liquid effluent from radwaste effluent are determined for each batch prior to release. Each isotope concentration is compared to ten times the 1 OCFR20 Appendix B, Table 2, Column 2 Effluent Concentration Values (TRO 3.11.1.1).

Tritium Liquid effluent quarterly tritium concentrations are compared to ten times the 10 CFR 20 Appendix B, Table 2, Column 2, Effluent Concentration value of 1.OE-03 pCi/ml to unrestricted areas.Dissolved and Entrained Gases Liquid effluent concentrations for dissolved and entrained gases are compared to the limiting value for total noble gas activity of 2.OE-04 pCi/ml (TRO 3.11.1.1).

Radionuclide Fractional Summation The sum of the percents of applicable limits for fission and activation products, tritium and dissolved and entrained gases must be less than 100%.1-12 SECTION 2 EFFLUENT AND WASTE DISPOSAL DATA 2-1 Airborne Effluents Summaries of the radionuclide total curie activities and average release rates are included in Tables 2-1 and 2-2. Carbon-14 (C-14) activity released is not included in Tables 2-1 or 2-2. C-14 released in airborne effluents is calculated based on conservative methodology provided by the Electric Power Research Institute (EPRI Report No. 1021106).

See Section 4 for additional details on the calculation of C-14 released in 2011 from the Susquehanna station. If a radionuclide was not detected, zero activity was used for that isotope in dose calculations and the activity is listed as"<MDC" (less than the minimum detectable concentration) in Tables 2-1 and 2-2.<MDC indicates that no activity was positively detected in any sample when samples were analyzed with techniques which achieved the required Lower Limits of Detection (LLD) as specified in the Technical Requirement (TRO) Table 3.11.2.1-1, Radioactive Gaseous Effluent Sampling and Analysis Program. In all cases, the measurement laboratory MDCs were at or below the LLD levels required by Technical Requirements.

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 supplemental 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 2011, 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 2011 Parameter Percent Valid Data Recovery Wind Speed 1Oin -Primary (1) 99.3 Wind Speed 60m -Primary 99.3 Wind Speed 10m -Backup (2) 99.5 Wind Speed 10m -Downriver (3) 100.0 Wind Direction 10m -Primary 98.4 Wind Direction 60m -Primary 98.4 Wind Direction 10m -Backup 99.6 Wind Direction 10m -Downriver 100.0 Temperature 10m -Primary 99.4 Dew Point 10m -Primary 100.0 Delta Temperature 60m -Primary 99.0 Sigma Theta lOm -Primary 98.4 Sigma Theta 60m -Primary 98.4 Sigma Theta 10m -Backup 99.6 Sigma Theta 10m -Downriver 100.0 Precipitation
