Summary and Conclusions Concentrations of naturally occurring actinium-thorium-228 and radium-226 were consistent with those of previous years.

Cow milk samples were analyzed for concentrations of iodine-131 as well as other gamma emitting nuclides. All iodine results were less than the MDC.

Concentrations of naturally occurring K-40, and thorium-228 were consistent with those detected in previous years.

No fission or activation products were detected.

Potatoes, green beans, pumpkins, soybeans and field corn which were irrigated with Susquehanna River water downstream of the SSES were sampled.

These food products were sampled during the harvest season and analyzed for concentrations of gamma emitting nuclides. Concentration of naturally occurring K-40 was found consistent with those in previous years.

No fission or activation products were detected.

Ground Water Ground water samples were analyzed for concentrations of tritium and gamma emitting nuclides. Tritium was observed in 22 of 61 samples above analysis MDC's in 2010. The activity was slightly above MDC. The source of the tritium can be attributed to routine airborne effluent releases from Susquehanna operations due to recapture and washout into precipitation. This tritiated precipitation makes its way into surface water and soil where it eventually seeps into shallow ground water. No fission or activation products were detected.

Summary and Conclusions Radionuclides Contributingto Dose from SSES Operation Of the two man-made radionuclides reported in the environment by the SSES REMP (i.e. H-3 and Cs-137),

tritium is the only radionuclide attributable to SSES operation.

The whole body and organ dose to members of the public attributable to tritium identified in REMP blowdown samples was 9.77E-04 mrem.

Tritium was included in the dose calculation because it was identified in the REMP samples of water being discharged to the river. The concentration of tritium in the water and the volume of water discharged were used to determine the amount of tritium released. The presumed exposure pathways to the public from this radionuclide were drinking water taken from the Susquehanna River at Danville, PA, and eating fish caught near the SSES discharge to the river.

These assumptions are based on the fact that tritium does not emit gamma radiation and the beta radiation emitted by tritium is not sufficiently penetrating to reach an individual on the shore.

Introduction Radioactivity levels in environmental media are usually so low that their measurements, even with state-of-the-art measurement methods, typically have significant degrees of uncertainty associated with them (Reference 5). As a result, expressions are often used when referring to these measurements that convey information about the levels being measured relative to the measurement sensitivities. Terms such as "minimum detectable concentration" (MDC) are used for this purpose. The MDC is an "a priori" estimate of the capability for detecting an activity concentration by a given measurement system, procedure, and type of sample.

Counting statistics of the appropriate instrument background are used to compute the MDC for each specific analysis. The formulas used to calculate MDCs may be found in procedures referenced in Appendix A.

The methods of measurement for sample radioactivity levels used by PPL's contracted REMP radioanalytical laboratories are capable of meeting the analysis sensitivity requirements found in the SSES Technical Requirements.

Other media, such as low-level radioactive discharges enter sediment, can be useful for trending the river. The upstream monitoring radioactivity levels in the aquatic locations serve as controls to provide pathway, primarily because of their data for comparison with downstream tendency to assimilate certain materials monitoring results. The potential exists that might enter the surface water to for radioactive material that might be which they are exposed. The results present in SSES airborne releases to from monitoring all of these media enter the Susquehanna River upstream provide a picture of the aquatic pathway of the plant through either direct that is clearer than that which could be deposition (e.g., settling or washout) or obtained if one or more were not by way of runoff from deposition on included in the REMP. land adjacent to the river.

The preoperational years 1976, 1978, and 1980 were exceptional years in the sense that iodine- 131 activity was observed in excess of MDCs due to fallout from atmospheric nuclear weapons testing. Iodine- 131 activity was also measured at levels exceeding MDCs in milk samples in 1986 in the vicinity of the SSES as a result of the Chernobyl incident.

With the exception of the naturally occurring potassium-40, and thorium-228 no gamma-emitting radionuclides were measured in excess of analysis MDCs in 2010. The 2010 means for indicator and control location potassium-40 activity were 1,300 pCi/liter and 1,310 pCi/liter, respectively. The potassium-40 activity in milk is not attributable to SSES operation because it is naturally occurring.

Ground Water Monitoring-Precipitation will invariably become groundwater background (12F3 control) groundwater via infiltration through soil from 1980-81 was approximately 120 and into groundwater. The highest pCi/1 and is located 5.2 miles WSW of average tritium concentration in the Susquehanna site.

precipitation on-site was 350 pCi/l from Sites 3 and 4 located on the west side of the station reactor buildings. In 2010, the tritium in rainwater samples ranged from -54.8 to 1070 pCi/l compared to 28 to 1350 pCi/l in 2009. Liquid is not always present in the collection devices during dry months, thus quarterly and annual tritium averages are generally only representative of wetter months.

The decreasing trend in tritium in the perimeter drain system parallels the decrease in tritium in precipitation seen in Figure 14.

The perimeter foundation drain system is below grade (approximately 28 feet) and serves to reduce hydrostatic pressure from groundwater on the building structures. Precipitation and storm water runoff may also enter these drains via infiltration. Groundwater results from the perimeter drains and monitoring wells (MW-1, MW-2, MW-3, MW-4, MW-10, MW-6, MW-8A) have tritium concentrations that are slightly above MDC. The source of the tritium at these locations can be attributed to precipitation washout of tritium from routine airborne effluent releases. Its evident that elevated tritium levels found within sub-surface groundwater in close proximity to the station is influenced by station airborne emissions and tritiated precipitation washout. The impact of the station tritium emissions on groundwater activities is dependent on the distance from the station, groundwater depth and general dispersion conditions around the station.

Location 6S5 is a sample from the Susquehanna River downriver of the SSES discharge diffuser. Station 6S5 was grab sampled weekly. Locations 4S7, 5S12, 7S12, and LTAW were grab sampled quarterly.

(d) Water from location 12H2 was retrieved weekly. Composite samples of the weekly collections at this location were made monthly (MC) for analysis.

Sampling at 12H2 was performed using an automatic composite sampler (ACS) that was operated in the time-proportional mode.

(e) Locations 5E2, 10D3, 10GI, and 13E3 were sampled bi-weekly from April through October when cows are on pasture, monthly otherwise.

(f) Zehner Farm (11D 1) grew pumpkins and soy beans and Lupini Farm -

Mifflinville Field (12F7) grew potatoes, green beans, and field corn irrigated with Susquehanna River water taken downstream of the SSES. No other fields were identified using river water downstream of the SSES in 2010.

APPENDIX D 2010 LAND USE CENSUS RESULTS 2010 Radiological Environmental Monitoring Report D-1

Appendix D 2010 LAND USE CENSUS RESULTS Ecology III, Inc. conducted a Land Use Census, during the 2010 growing season around the SSES, to comply with the Offsite Dose Calculation Manual. The purpose of the survey was to document the nearest milk animal, residence, and garden greater than 50 m2 (approx. 500 ft2) producing broad leaf vegetation within a distance of 8 km (approx.

5 miles) in each of the 16 meteorological sectors surrounding the SSES.

SUMMARY

OF CHANGES FROM 2009 TO 2010 Since the 2009 census, there was one change in the nearest residence, four changes in the nearest garden, and one change in dairy farms within the 5 mile radius.

Residence Census:

The residence census was conducted from 24 August through 27 September 2010.

Distances of the nearest residences from the Susquehanna SES in the 16 different sectors ranged from 0.5 (J.Futoma, Sector 7 and R. Panetta, Sector 6) to 2.1 miles (R.

Dickosky, Sector 4), with an average of approximately 1.0 miles.

The only change from the 2009 census was a new resident in sector 4 (Dickosky replacing Barberi).

Garden Census:

The garden census was conducted from 24 August through 27 September 2010.

Distances of the nearest gardens from the Susquehanna SES in the 16 different sectors ranged from 0.6 miles (T. Scholl, Sector 7) to 4.0 miles (P. Culver, Sector 16), with an average of 2.1 miles.

Changes from the 2009 census included:

• Sector 3 - M. Welch replaced F. Kremski

• Sector 5 - L. Kozlowski/W. Witts replaced W. Daily

• Sector 11 - R. Broody replaced D. Bankes

• Sector 15 - D. Goff replaced R. Reider F. Kremski did not plant a garden in 2010, F. Kozlowski/W. Witts, R. Broody, and D.

Goff planted gradens that were closer to Susquehanna SES (all have had gardens in previous years).

Dairy Animal Census:

Five dairy animal sites were identified in the census conducted on 26 July 2010. The Davis farm (sector 10) was included in the dairy census because they participated as a milk sampling control location. Cows were present at all sites; no dairy goats found.

Report D-2 2010 Environmental Monitoring Radiological Environmental 2010 Radiological Monitoring Report D-2

Appendix D There was one change in dairy farm locations from 2009 to 2010: F. Rinehimer (Sector

6) stopped milking operations in October 2009.

Irrigation Two farms irrigated crops using Susquehanna River water downriver from the Susquehanna SES in 2010: Zehner Farm (location 11D1, 3.3 miles SW) irrigated pumpkins and soy beans and Lupini Farm-Mifflinville Field (location 12F7, 8.3 miles WSW) irrigated potatoes, green beans, and field corn. No control samples were collected during the 2010 growing season because no irrigation with river water had taken place at the control site.

No other crops or fields were irrigated because soil moisture was adequate. Overall results of the survey are summarized below:

Appendix G The averages for indicator and control locations reported in the Summary of Data Table, which summarizes the entire year's results for the SSES REMP, were calculated using all measured values, when available, whether or not they were reported in Appendix I tables. Values below the MDCs, even zeroes and negatives, were part of the averaging process for these analysis results. When no measured results are available in these cases, "LLD" is reported.

Preferably, the averages reported in the Summary of Data table for sample media that are normally collected continuously are determined using only results from continuously collected samples. Occasionally, grab samples are taken for these media when equipment malfunctions or other anomalies preclude or otherwise perturb routine continuous sampling. These grab samples are taken to minimize the time periods when no sampling is being performed, or, in some instances, when continuous sampling is considered to be nonrepresentative.

Because grab samples are snapshots of the media over brief periods, it is preferable not to average the analysis results of these samples with those for continuously collected composite samples. However, when equipment malfunctions are protracted, relatively large periods of time could be entirely unrepresented by averages if the results from grab sample analyses are not considered.

Allowing analysis results for grab samples to be weighted equally with those representing relatively large periods of time would tend to bias the resulting averages unjustifiably towards the conditions at the times that the grabs are obtained. Averages obtained in this way might less accurately reflect the conditions for the combined period of continuous sampling and grab sampling than if only the results from continuous sampling were used. On the other hand, using weighting factors for the analysis results of grab samples derived from the actual time it takes to collect those samples would lead to the grab sample analysis results having a negligible effect on the overall average and not justifying the effort involved.

Grab samples collected in lieu of normal continuous sampling are typically obtained at regular intervals corresponding to the intervals (weekly) at which the continuously collected samples would usually be retrieved for eventual compositing. For example, grab samples are collected once a week but may be composited monthly in place of continuously collected samples that would normally be retrieved weekly and composited monthly. Since each grab sample is used to represent an entire week, albeit imperfect, it is reasonable to weight the analysis results the same. Thus, the results of one weekly grab are given approximately one-fourth the weight of the results for a monthly composite sample collected continuously for each of the four weeks in a month. Similarly, the analysis results of a composite of four weekly grab samples would carry the same weight as the analysis results for a composite of four weeks of continuously collected sample.

Appendix H The data presented in the following tables were included if specific analysis results routinely exceeded the applicable MDCs in 2009 and/or routinely may have done so in previous years. The comparisons may be useful for observing any step changes that may occur in the environment over a long period. However, the importance attached to these comparisons should be tempered by the understanding that changes in methods of analysis, typical MDCs achieved by the analyses, and averaging methods over the years may tend to blur the picture in some cases.

APPENDIX I SPECIFIC ANALYSIS. RESULTS TAUATDB t7MEDIAAND.SANLPLJNGiPERIOD 2010 Radiological Environmental Monitoring Report I-I

Appendix I Results of analyses are generally reported in the following tables to two significant figures. Random uncertainties of counting are reported to the same decimal place as the result.

Calculated values for analysis results are reported with the random uncertainty of counting at two standard deviations (2S), determined by considering both the sample and background count rates. The uncertainty of an activity is influenced by the volume or mass of the sample, the background count rate, the count times, the method used to round off the value obtained to reflect its degree of significance, and other factors. The uncertainties of activities determined by gamma spectrometric analyses are also influenced by the relative concentrations of the radionuclides in the sample, the energies and intensities of the gammas emitted by those radionuclides, and the assumptions used in selecting the radionuclides to be quantitatively determined.

Results reported as less than (<) in these tables are below the minimum detectable concentrations (MDCs). The MDC is an estimate of the detection capabilities of the overall measurement method, taking into account not only the counting system, but also the characteristics of the sample being counted. When the MDC is used as the level to decide whether or not to enter a measured value into a table, there is a 50% chance that the value will be entered when the actual sample activity is equivalent to the MDC.

There is only a five percent chance that a value representing a fluctuation in background activity will be entered as sample activity in such an instance.

Measured values for the activities of specific radionuclides, such as the man-made gamma-emitting radionuclides iodine-131 and cesium-137, only appear in the following tables for each specific medium when the levels that are measured exceed the MDC values for those measurements and those radionuclides are actually identified as present in the samples. Measured values for the analyses that are not radionuclide specific, such as gross alpha and beta analyses, also are presented in the tables for specific media only when the levels that are measured actually exceed the MDCs.

(2) A standard (std.) quarter (qtr.) is considered to be 91.25 days. Results obtained for monitoring periods of other durations are normalized by multiplying them by 91.25/x, where x Is the actual duration indays of the period.

(3) Uncertainties for Individual monitoring location results are two standard deviations of the elemental doses of six calcium elements from the two TLDs assigned to each monitoring location, representing the variability between the elemental doses of eachlof the six TLD elements.

(4) No measurement could bemadeat this location because the TLDs were lost, stolen, or damaged. Refer to Appendix A of the Annual Radiological Environmental Operating Report for an explanation of program exceptions to REMP.

(5) Uncertainties associated with quarterly indicator and control averages are two standard deviations, representing the variability between the results of the individual monitoring locations.

APPENDIX J Report J-1 2010 Radiological Environmental Monitoring Radiological Environmental Monitoring Report J-1

Appendix J The data in the tables that follow show how well Teledyne Brown Engineering Environmental Services (TBE) performed in the analysis of radioactively spiked media. Tables J- 1 through J-4 provide the performance results for TBE. In addition to the Analytics' spikes analyzed as part of PPL's REMP Laboratory Spike Program (Table J-3), TBE analyzed spikes procured independently from Analytics as part of their respective Quality Control Spike Programs (Table J-2), as well as spikes prepared as part of the following programs:

1. The Proficiency Testing Program of Environmental Resource Associates (Table J- 1)

2. The Mixed Analyte Performance Evaluation Program (MAPEP) of the DOE (Table J-4)

It should be noted that program #1 above only provides spiked water for analyses. No other media are included in the spikes provided by this program. The following characteristics are important for the spiked environmental media:

1. When practical, the level of activity in, at least, some of the spiked environmental media should be within the range between required analysis sensitivities for the SSES REMP and the Reporting Levels, if applicable, of the NRC.

2. The spikes should be preserved in a manner as similar as possible to the way that actual samples of those media are prepared.

3. The variety of radionuclides with which environmental media are spiked should be as extensive as practical, including as many of the activation and fission products that could be detected in the vicinity of the SSES as reasonable.

The spiked environmental media prepared by Analytics according to the requirements of PPL's REMP Laboratory Spike Program are intended to incorporate characteristics #1, #2, and #3 to the greatest degree that is practical.

Report J-2 2010 2010 Radiological Environmental Monitoring Radiological Environmental Monitoring Report J-2

Appendix I The criteria for the acceptability of the analyses results for the spikes prepared as part of the PPL REMP Laboratory Spike Program (Table J-3) has been established by PPL. They are based on criteria that were originally developed by the NRC. The NRC bases these criteria on an empirical relationship that combines prior experience and accuracy needs. As the resolution of the measurement process improves (relative measurement uncertainty becomes smaller), the criteria for determining acceptability become tighter. Conversely, as the resolution of the process becomes poorer (relative measurement uncertainty becomes bigger), the criteria are widened.

The criteria for acceptability of DOE (MAPEP) program - Table J-4 is based on control limits based on percentiles of historic data distributions.

Note that comment numbers at the extreme right side of the tables denote unacceptable results in Tables J- 1 through J-4. Discussions relevant to these comment numbers follow the presentations of the data, as applicable.
