SUMMARY

AND CONCLUSIONS Radiological Dose Impact This report on the Radiological Environmental Monitoring Program covers the year 2008.

During that period, 1349 analyses were performed on 1072 samples at 42 sampling locations. Additionally, 226 TLD direct radiation measurements were performed at 57 locations around the site.

In assessing all the data gathered and comparing with SSES pre-operational data, it was concluded that the operation of SSES had no adverse radiological impact on the health and safety of the public or the environment.

The total whole body dose from both ingested radionuclides and direct radiation from SSES Operations is negligible compared to the public's exposure from natural background radiation, medical irradiation, and radiation from consumer products of more than 300 millirem/year.

The following graph compares public dose from SSES operation to that from other sources of radioactivity and radiation.

2008 Radiological Environmental Monitoring Report 1

Summary and Conclusions Ambient Gamma Radiation Environmental direct radiation measurements were performed quarterly on and around the SSES site using thermoluminescent dosimeters (TLDs).

The maximum direct radiation dose from SSES operation to a member of the public was approximately 3.80E-02 mrem for all of 2008. This dose represents approximately 0.15% of the 25-mrem whole-body SSES Technical Requirements (TRO 3.11.3) limit for all SSES sources of radioactivity and radiation.

Aquatic Environment Surface water samples were analyzed for concentrations of tritium, iodine-131, and gamma emitting nuclides.

Drinking water samples were analyzed for concentrations of gross beta, tritium and gamma emitting nuclides. Gross beta activities detected in drinking water were consistent with those reported in previous years.

Iodine-131 activity was detected in 6 of 36 surface water samples. Evidence indicates that it is there only as the result of the discharge of medical waste to the Susquehanna or Lackawanna Rivers through sewage treatment plants upstream of the SSES. Iodine-131 was not reported to have been discharged with water released from the SSES to the Susquehanna River during 2008.

Tritium activity attributable to SSES operation was detected in the aquatic pathway to man. The maximum dose from the ingestion of tritium was estimated at the nearest downriver municipal water supplier via the drinking water pathway and near the outfall of the SSES discharge to the Susquehanna River via the fish pathway. The maximum whole body and organ doses due to tritium identified via REMP samples is approximately 7.60E-04 mrem/year. This dose is less than one-tenth of one percent of the dose guidelines stated in 10 CFR 50, Appendix I.

Fish samples were analyzed for concentrations of gamma emitting nuclides. Concentrations of naturally occurring K-40 were consistent with those detected in previous years. No fission or activation products were detected in fish.

Sediment samples were analyzed for concentrations of gamma emitting nuclides. Cesium-137 was observed in 1 of 6 sediment samples and attributed to non-SSES sources (residual fallout from atmospheric weapons testing).

Concentrations of naturally occurring K-40, radium-226, and actinium-thorium-228 were found consistent with those detected in previous years.

Atmospheric Environment Air particulate samples were analyzed for concentrations of gross beta and gamma emitting nuclides. Cosmogenic Be-7 was detected at levels consistent with those detected in previous years.

Air iodine samples were analyzed for concentrations of iodine-131. All results were less than the MDC.

Summary and Conclusions Terrestrial Environment Soil samples were analyzed for concentrations of gamma emitting nuclides. Cesium-137 was observed in 3 of 4 soil samples and attributed to non-SSES sources (residual fallout from atmospheric weapons testing).

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

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, actinium-228, and thorium-228 were consistent with those detected in previous years. No fission or activation products were detected.

Pumpkins, green beans, and potatoes which were irrigated with Susquehanna River water downstream of the SSES were. samp'led. These food products were sampled during the harvest season and analyzed for concentrations of gamma emitting nuclides.

Concentrations of naturally occurring K-40, actinium-228, and thorium-228 Were 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 21 of 44 samples above analysis MDC's in 2008. The activity was slightly 'above the local background. 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 Relative Radionuclide Activity Levels in Selected Media Some media monitored in the environment are significant for the numbers of gamma-emitting radionuclides routinely measured at levels exceeding analysis MDCs.

Sediment in the aquatic pathway and soil in the terrestrial pathway are two such media.

The following graphs show the relative activity contributions for the types of gamma-emitting radionuclides reported at levels above the analysis MDCs in sediment and soil at indicator locations during 2008.

Summary and Conclusions Radionuclides Contributing to Dose from SSES Operation Of the three man-made radionuclides reported in the environment by the SSES REMP (i.e. H-3, 1-131 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 7.60E-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 Su'squehanna 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 iadiation, and thebeta radiation-emitted by tritium is not sufficiently penetrating to reach an individual on the shore.

INTRODUCTION Radiolomical Environmental Monitoring Program (REMP)

The SSES is located on approximately an 1500-acre tract along the Susquehanna River, five miles northeast of Berwick in Salem Township, Luzerne County, Pennsylvania. The area. around the site is primarily rural, consisting predominately of forest and agricultural lands. (More specific information on the demography, hydrology, meteorology, and land use characteristics of the area in the vicinity of the SSES can be found in the Environmental Report (Reference 1),

the Final Safety Analysis Report (Reference 2), and the Final Environmental Statement (Reference 3) for the SSES.)

The SSES implements the REMP in accordance with Technical Specifications, Technical Requirements Manual and the Offsite Dose Calculation Manual, which are based on the design objectives in 10CFR Part 50 Appendix I, Sections IV.B.2, IV.B.3, and IV.C.

The REMP supplements the results of the radioactive effluent-monitoring program by Verifying that the measurable concentrations of radioactive materials and levels of radiation in the environment are not higher than expected on the basis of the effluent measurements and modeling of the environment in the vicinity of the SSES.

Key objectives of the SSES REMP are as follows:

Document compliance with SSES REMP Technical Requirements radiological environmental surveillances

" Verify proper implementation of SSES radiological effluent controls

" Identify, measure, and evaluate trends of radionuclide concentrations in environmental pathways near SSES

Assess impact of SSES Effluents on the environment and the public PPL has maintained a Radiological Environmental Monitoring Program (REMP) in the vicinity of the Susquehanna Steam Electric Station Units 1 and 2 since April, 1972, prior to construction of both units and ten years prior to the initial operation of Unit 1 in September, 1982. The purpose of the preoperational REMP (April, 1972 to September, 1982) was to establish a baseline for radioactivity in the local environment that could be compared with the radioactivity levels observed in various environmental media throughout the operational lifetime of the SSES. This comparison facilitates assessments of the radiological impact of the SSES operation.

Introduction Potential Exposure Pathways The three pathways through which radioactive material may reach the public from nuclear power plants are the atmospheric, terrestrial, and aquatic pathways. (Figure 1 depicts these pathways for the intake of radioactive materials.)

Mechanisms by which people may be exposed to radioactivity and radiation in the environment vary with the pathway.

Three mechanisms by which a member of the public has the potential to be exposed to radioactivity or radiation from nuclear power plants such as the SSES are as follows:

inhalation (breathing) ingestion (eating and drinking), and whole body irradiation directly from a plant or from immersion in the radioactive effluents.

REMP Scope The scope of the SSES REMP was developed based on the NRC's Radiological Assessment Branch Technical Position on radiological environmental monitoring, as described in Revision 1, November 1979 (Reference 4). However, the REMP conducted by PPL for the SSES exceeds some of the monitoring suggested by the NRC's branch technical position, in terms of the number of monitoring locations, the frequency of certain monitoring, the types of analyses required for the samples, and the achievable analysis sensitivities.

During the operational period of the SSES, two different categories of monitoring locations, called control and indicator locations, were established to further assist in assessing the impact of station operation. Control locations are located at sites where it is considered unlikely that radiation or radioactive material from normal station operation would be detected. Indicator locations are sited where it is expected that radiation and radioactive material that might originate from the station would be most readily detectable.

Control locations for the atmospheric and terrestrial pathways are more than 10 miles from the station. Preferably, the controls also are in directions from the station less likely to be exposed to wind blowing from the station than are the indicator locations. Control locations for the aquatic pathway, the Susquehanna River, are upstream of the station's discharge to the river.

Indicator locations are selected primarily on the basis of proximity to the station, although factors such as meteorology, topography, and sampling practicality also are considered.

Indicator locations for the atmospheric and terrestrial pathways are typically less than 10 miles from the station.

Most often, they are within 5 miles of the station. Indicator locations in the Susquehanna River are downstream of the station's discharge. Monitoring results from indicator locations are compared with results from control locations. These comparisons are made to discern any differences in the levels and/or types of radioactive material and/or radiation that might exist between indicators and controls and that could be attributable to the station.

2008 Radiological Envirommental Monitoring Report

Introduction In 2008, the SSES REMP collected 1072 samples at 42 locations and performed 1, 349 analyses. In addition, the REMP monitors ambient radiation levels using thermoluminescent dosimeters* (TLDs) at 57 indicator and control locations, resulting in 226 radiation level measurements in 2008.

The media monitored and analyses performed are summarized in the table below. Figures*2 through 7 display the REMP TLDs and sampling locations in the vicinity of the SSES. Appendix C provides directions, distances, and a brief description of each of the locations in Figures 2 through 7.

REMP Monitoring Sensitivity Detection of radiation and radioactive material from the SSES in the environment is complicated by the presence of naturally occurring radiation and radioactive materials from both terrestrial and cosmic sources. Man-made radiation and radioactive material from non-SSES sources, such as fallout from previous nuclear Weapons tests and medical wastes, also can make identification of SSES radiation and radioactive material difficult. Together, this radiation and radioactive material present background levels from which an attempt is made to distinguish relatively small contributions from the SSES. This effort is further complicated by the natural variations that typically occur from both monitoring location to location and with time at the same -locations.

The naturally occurring radionuclides potassium-40, beryllium-7, actinium:-228, thorium-228; and tritium are routinely observed in certain environmental media. Potassium-40 has been observed in all monitored media and is routinely seen at readily detectable levels in such media as milk, fish, fruits and vegetables. SeasOnal variations in beryllium-7 in air samples are regularly observed. Man-made radionuclides, such as cesium-37 left over from nuclear weapons testing are often observed as well. In addition, the radionuclide tritium, produced by both cosmic radiation interactions in the upper atmosphere as well as man-made (nuclear weapons), is another radionuclide typically observed.

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.

Ambient Radiation Monitoring AM BIEN RADIATION MONITORING INTRODUCTION The primary method for the SSES REMP measurement of ambient radiation levels is the use of thermoluminescent dosimeters (TLDs).

The TLDs are crystals (calcium sulfate) capable of detecting and measuring low levels of radiation by absorbing a portion of the radiation's energy that is incident upon them and storing the captured energy until the TLDs are processed (read). Processing involves heating the TLDs to release their stored energy in the form of light and measuringthe intensity of the light that they emit. The intensity of the emitted light is proportionalto the amount of radiation to which they were exposed.

Calibration of the TLD processors permits a reliable relationship to be.

established between the light emitted and the amount of radiation dose received by the. TLDs. The result permits accurate measurements of the ambient radiation in the environment.

Environmental TLDs are continually exposed to natural radiation from the ground (terrestrial radiation) and from the sky (cosmic) radiation. In addition, they also may be exposed to man-made radiation. Most of the environmental TLD's natural radiation exposure comes from sOurces in the ground. These terrestrial sources vary naturally with time due, to changes in soil moisture, snow cover, etc. The natural-radiation picture is complicated because the factors affecting radiation reaching the TLDs from the ground vary differently with time from one location to another due to locational differences in such factors as soil characteristics (amounts of organic matter, particle size, etc.),

drainage opportunities, and exposure to sunlight. Environmental TLDs can also be affected by direct radiation (shine) from the SSES turbine buildings during operation, radw aste transfer and storage, and radioactive gaseous effluents from the SSES.

Unfortunately, TLDs do not have any inherent ability to indicate the source of the radiation to which they are exposed.

The placementof numerous TLDs in the environment can facilitate decision-making about the possible radiation sources to Which TLDs are exposed.

However, a method for evaluating TLD data is still required. The SSES REMP relies on a statistically based approach to simultaneously compare indicator TLD data with control TLD data and operational TLD data with preoperational TLD data. This approach peirmts the flagging of environmental TLD doses that might have been produced by both man-made sources of radiation, as well as natural radiation sources. It also provides a means for attributing a portion of the total TLD dose to SSES operation if appropriate.

Interpretation of environmental TLD results is described in PPL Nuclear Engineering Study, EC-ENVR-1012 (Revision 0, January 1995).

2008 Environmental Radiological Monitoring Report 17

Ambient Radiation Monitoring Scope Direct radiation measurements were made using Panasonic 710A readers and Panasonic UD-814 (calcium sulfate) thermoluminescent dosimeters (TLD).

During 2008, the SSES REMP had 46 indicator, 6 special interest and 5 control TLD locations. Refer to Table C1 for TLD measurement locations.

The TLD locations are placed on and around the SSES site as follows:

A site boundary ring (i.e. an inner ring) with at least 1 TLD in each of the 16 meteorological sectors, in the general area of the site boundary. Currently there are 30 locations. They are: (1S2, 2S2, 2S3, 3S2, 3S3, 4S3, 4S6, 5S4, 5S7, 6S4, 6S9, 7S6, 7S7, 8S2, 8A3, 9S2, 9B1, 1OS1,10S2, 11S7, 12S1, 12S3, 12S7, 13S2, 13S5, 13S6, 14S5, 15S5, 16S1 and 16S2) near and within the site perimeter representing fence post doses from a SSES release.

An outer distance ring with at least 1 TLD in each of the 16 meteorological sectors, in the 3 to 9 mile range from the site. Currently there are 16 locations.

They are: (1D5, 2F1, 3El, 4E2, 5E2, 6E1, 7E1, 8D3, 9D4, IOD1, llE1, 12D2, 13E4, 14D1, 15Fi and 16F1).

These TLD's are located to measure possible exposures to close-in population.

The balance of TLD locations represents the special interest areas such as population centers, schools, residences and control locations.

Currently there are six special interest locations (6A4, 15A3, 16A2, 8B2, 10B3 and 12El) and 5 control locations (3G4, 4G1, 7G1, 12G1 and 12G4).

The specific locations were determined according to the criteria presented in the NRC Branch Technical Position on Radiological Monitoring (Revision 1, November 1979).

Monitoring Results TLDs The TLDs were exchanged quarterly and processed by the SSES Health Physics Dosimetry Group. Average quarterly ambient gamma radiation levels measured by environmental TLDs is shown in the bar graph below.

Ambient Radiation Monitoring The highest, estimated, gamma radiation dose of 3.80 E-02 mrem for 2008 was at location 9S2. It is assumed that the occupancy time for a member of the public is no more than one hour each calendar quarter at location 9S2.

This dose is approximately 0.15% of the 25 mrem whole-body SSES Technical Requirements (TRO. 3.11.3) limit for all SSES sources of radioactivity and radiation.

Aquatic Pathway Monitoring AQUATIC PATHWAY MONITORING INTRODUCTION In 2008 the SSES REMP monitored the following media in the aquatic pathway:

surface water, drinking water, fish, sediment, fruits and vegetables. Some of the media (e.g.,. drinking water and fish) provide information that can be especially useful to the estimation of possible dose to the public from potentially ingested radioactivity, if detected. Other media, such as sediment, can be useful for trending radioactivity levels in the aquatic pathway, primarily because of their tendency to assimilate certain materials that might enter the surface, water to which they. are exposed. The results from monitoring all of these media provide a picture of the aquatic pathway that is clearer than that which could be obtained if one or more were not included in the REMP.

SSES Technical Requirements only require that fruit and vegetables be sampled at locations irrigated by Susquehanna River water from points downstream of the SSES discharge to the River. The land use census (Reference 11) conducted in 2008 identified three farms within 10 miles downriver of PPL Susquehanna that used Susquehanna River water for irrigation. The Zehner Farm (location 11D1, 3.3 miles SW) irrigated pumpkins. The Chapin Farm-Drake Field (location 11F2, 5.5 miles SW) irrigated green beans. The Lupini Farm

- Mifflinville Field (location 12F7, 8.3 miles WSW) irrigated potatoes. A control sample of irrigated potatoes upriver from PPL Susquehanna discharge was also collected from the Chapin Farm - PPL-Parcel 25 (location 5511, 1.1 miles East). No other fields within 10 miles downriver of Susquehanna SES were irrigated in 2008.

The aquatic pathway in the vicinity of the SSES is the Susquehanna River.

Monitoring of all of the aquatic media, except drinking water, is conducted both downstream and upstream of the location from which occasional SSES low-level radioactive discharges enter the river. The upstream monitoring.

locations serve as controls to provide data for comparison with downstream monitoring results. The potential exists for radioactive material that might be present in SSES airborne releases to enter the Susquehanna River upstream Of the plant through either direct deposition (e.g., settling or washout) or by way of runoff from deposition on land adjacent to the river. However, direct deposition and runoff are considered to be insignificant as means of entry for SSES radioactivity into the Susquehanna River when compared to liquid discharges under normal conditions.

Lake Took-a-While (LTAW), which is located in PPL's Riverlands Recreation Area adjacent to the Susquehanna River, is also considered to be part of the aquatic pathway for monitoring purposes. Although it is not in a position to receive water discharged to the river from the SSES, it does receive 2008 Radiological Environmental Monitoring Report 21 2008 Radiological Environmental Monitoring Report 21

Aquatic Pathway Monitoring storm runoff from the SSES. Storm runoff from the SSES site should not normally contain any measurable radioactivity from the plant. However, the SSES REMP, consistent with other aspects of aquatic monitoring and the REMP, in general, goes beyond its requirements by monitoring LTAW.

Scope Surface Water Surface water was routinely sampled from the Susquehanna River at one indicator location (6S5/Outfall Area) and one control location (6S6/River Water Intake Line) during 2008.

Sampling also took place at the following additional indicator ibcations:

the SSES discharge line to the river (2S7), Lake Took-A-While (LTAW) and the Peach Stand Pond (4S7).

Additionally, a grab sample of the Susquehanna River was taken once at location 5S9 (Environmental Lab Boat Ramp) when station 6S6 malfunctioned.

Drinking Water Drinking water samples were collected at location 12H2, the Danville Municipal Water Authority's treatment facility on the Susquehanna River, in 2008. Treated water is collected from the end of the processing flowpath, representing finished water that is suitable for drinking. This is the nearest point downstream of the SSES discharge to the River at which drinking water is obtained. No drinking water control location is sampled. For all intents and purposes, control surface water sampling location (6S6) would be suitable for comparison.

Fish Fish were sampled from the Susquehanna River in the spring and fall of 2008, at one indicator location, IND, downstream of the SSES liquid discharge to the River and one control location; 2H, sufficiently upstream to essentially preclude the likelihood that fish caught there would spend any time below the SSES discharge. In addition, fish were also sampled in the fall from PPL's Lake Took-a-While, location LTAW. This location is not downstream of the SSES discharge. It is sampled because of its potential for receiving runoff from the SSES.

LTAW is considered an indicator location.

Sediment Sediment sampling Was performed in the spring and fall at indicator locations 7B and 12F and control location 2B on the Susquehanna River.

Fruits and Vegetables Fruits and Vegetables were sampled at indicator locations 11 D 1, 11 F2 and 12F7. Additionally a control sample of irrigated potatoes upriver from the Susquehanna discharge was collected at location 5S 11. These locations were irrigated with Susquehanna River water in 2008. The edible portions are kept for analysis.

Sampling Surface Water Weekly water samples were collected at indicator location 6S5 for both biweekly and monthly compositing.

Location 6S5 was considered a backup for location 2S7 in the event that water 2008 Radiological Environmental Monitoring Report 22 2008 Radiological Environmental Monitoring Report 22

Aquatic Pathway Monitoring could not be obtained from the automatic samplers at these locations.

Routine samples for 6S5 were collected from a boat, unless river conditions prohibited boating. When this occurs, samples are collected from an alternate shoreline site located below the.

Susquehanna SES discharge diffuser.

The shoreline samples are collected at the, Wetlands Cottage area, approximately 100-150 yards down river from the 6S5 site.

Indicator location 2S7 the SSES Cooling Tower Blowdown Discharge (CTBD) line, and control location 6S6, the SSES River Water Intake structure, were time -proportionally sampled using automatic continuous samplers.

The samplers were typically set to obtain 30-60 ml aliquots every 20-25 minutes. Weekly, the water obtained by these samplers was retrieved for both biweekly and monthly compositing.

The other surface water monitoring locations, LTAWand Peach Stand Pond (4S7), were grab sampled once each quarter.

Drinking Water Treated Water was time-proportionally sampled by an automatic sampler. The sampler was typically set to obtain three 12-ml aliquots every twenty minutes.

Weekly, the Water obtained by this sampler was retrieved for monthly compositing.

Fish Fish were obtained by electrofishing.

Electrofishing stuns the fish and allows them to float to the surface so that those of the desired species and sufficient size can be sampled. Sampled fish include recreationally important species, such as smallmouth bass, and also channel catfish and shorthead redhorse. The fish are filleted and the edible portions are kept for analysis.

Sediment Shoreline sediment was collected to depths of four feet of water.

Fruits and Vegetables Pumpkins, green beans and potatoes which were irrigated with river water downstream from SSES, were sampled during the harvest season.

Sample Preservation and Analysis Surface and Drinking Water Surface water samples were analyzed monthly for gamma-emitting radionuclides and tritium actiVities:

One biweekly surface composite sample was analyzed for I-131 activity each month. Drinking water samples were analyzed monthly forbeta, gamma-emitting radionuclides, and tritium activities.

Sediment and Fish Fish are frozen until shipment. All samples are analyzed by gamma spectroscopy for the activities of any gamma emitting radionuclides that may be present.

Aquatic Pathway Monitoring Monitoring Results Surface Water Refer to the following for results of surface water analyses for 2008:

" Appendix G, Table G page G-3 and G-4, shows a summary of the 2008 surface Water data.

Appendix H, Tables H 3 and H 4, shows comparisons of iodine-131 and tritium monitoring results against past years data.

" Appendix I, Tables 1-2 and 1-3, shows specific results of tritium, gamma spectroscopic and iodine-131 analyses of surface water samples.

The Nuclear Regulatory Commission (NRC) requires that averages of the activity levels for indicator environmental monitoring locations and for control environmental monitoring locations of surface water, as well as other monitored media, be reported annually., Data from the following four surface Water monitoring locations were averaged together as indicators for reporting purposes: location (6S5) on the Susquehanna River downstream of the SSES, Lake-Took-a While (LTAW) adjacent to the river, and the SSES cooling tower blowdown discharge (CTBD) line to the river (2S7), and the Peach Stand Pond (Secondary Sediment Pond).

Technically, the CTBD line is not part of the environment. The CTBD line is a below ground pipe to which the public has no access, contrary to the other environmental monitoring locations on the Susquehanna River to which the public does have access. However, currently there is no automatic composite sampling of an indicator location on the Susquehanna River, so the CTBD line from the SSES is included as an indicator monitoring location in the radiological environmental monitoring program.

Most of the water enitering the Susquehanna River through the SSES CTBD line is simply water that was taken from the river upstream of the SSES, used for cooling purposes without being radioactively contaminated by SSES operation, and returned to the river.

Batch discharges of relatively small volumes of slightly radioactively contaminated water are made to the river through the SSES CTBD at times throughout each year.

The water is released from tanks of radioactively contaminated Water on site to the CTBD and mixes. with the noncontaminated water already present in the CTBD. Flow rates from the tanks containing radioactively contaminated water being discharged to the CTBD vary based on the radioactivity level of the batch release. In addition, the minimum flow rate for the returning water in the CTBD is maintained at a flow rate of 5,000 gpm or higher. These requirements are in place to ensure adequate dilution of radioactively contaminated water in the CTBD prior to entering the river.

At the point that CTBD water enters the river, additional, rapid dilution of the discharged water by the river is promoted by releasing it through a diffuser. The diffuser is a large pipe with numerous holes in it that is 2008 Radiological Environmental Monitoring Report 24 2008 Radiological Envirommental Monitoring Report 24

Aquatic Pathway Monitoring.

positioned near the bottom of the river.

CTBD discharges exit the diffuser through the many holes, enhancing the mixing of the discharge and river waters. The concentrations of, contaminants are reduced significantly as the discharged water mixes with the much larger flow of river water. The mean flow rate of the Susquehanna River in 2008 was approximately 7,350,000 gpmr.

The CTBD average flow during 2008 was, 9,653 gpm.

Based on the average river flow And the average CTBD flow during 2008, liquid discharges from the SSES blowdown line were diluted by approximately a factor of 800 after entering the river.

The amount of radioactively contaminated water being discharged is small. Nevertheless, sensitive analyses

of the water samples can often detect the low levels of certain types of radioactivity in the CTBD water following dilution. Though the levels of radioactivity measured in the CTBD

-water are generally quite low, they tend to be higher than those in the river downstream of the SSES. Most radionuclides discharged from the SSES CTBD are at such low levels in the downstream river water that, even with the sensitive analyses performed, they cannot be detected.

When the radioactivity levels from the CTBD samples throughout the year are averaged with those obtained from actual downstream monitoring locations, the result is an overall indicator location average that is too high to be representative of the actual average radioactivity levels of the downstream river water. As the following discussions are reviewed, consideration should be given to this inflation of average radioactivity levels from the inclusion of CTBD (location 2S7) results in the indicator data that is averaged.

Surface Water Iodine-131 Bi-weekly (once per month) samples from surface water locations were analyzed for concentrations of iodine-131 activity (Table 1-3 and Table G).

The 2008 indicator values range from

-0.255 to 1.95 pCi/l compared to -0.109 to 1.66 for 2007. Comparison of the 2008 mean iodine-131 activity of 0.48 pCi/I for all indicator locations to the average of the annual control mean of 0.36 pCi/l for pre-operational years suggest activity detected slightly above the average from 1979-81 (pre-operational) and the 2008 control mean.

Throughout the course of a year, iodine-131 is typically measured at levels in excess of analysis MDCs in some samples obtained from control surface water monitoring locations on the Susquehanna River upstream of the S SES. as Well as indicator locations downstream of the SSES. As, determined by measurements of samples obtained by the SSES REMP, the mean iodine-131 activity level from the CTBD for all of 2008 was 0.74 pCi/l compared to the control mean of 0.34 pCi/l for 2008. The 2008 mean iodine-131 activity of 0.25 pCi/I at the indicator 6S5 (Outfall Area) was slightly lower than the mean iodine-131 activity of 0.34 pCi/l at the control 6S6 (River Water Intake) location.

Iodine-131 from the discharge of medical wastes into the Susquehanna River upstream of the SSES is drawn into the SSES cooling tower basins 25 2008 Radiological Enviromnental Monitoring Report 25 200.8 Radiologidd Environmental Monitoring Report

Aquatic Pathway Monitoringe through the SSES River Water Intake Structure. It is reasonable to assume that concentration of the already existing iodine-131 in the cooling tower basins occurs as it does for other substances found in the river. For example, the SSES routinely assumes concentration factors in the basin for

.calcium of four to five times the concentrations in the river water entering the basins, based on past measurements. This concentrating effect occurs because of the evaporation of the water in the basins, leaving behind most dissolved and suspended materials in the unevaporated water remaining in the basins. If a concentration factor of four for iodine-131 were to be applied to the 2008 mean iodine-131 activity level for the control samples from the Susquehanna River, a mean concentration of 1.36 pCi/liter for iodine-131 in the basin water and the water being discharged from the basins would be expected. The actual 2008 mean of 0.74 pCi/1 for the CTBD mean is approximately half the expected mean.

Because iodine-131 is radioactive, unlike the calcium that has been measured, iodine-131 is removed from the water while it is in the basins through the radioactive decay process.

Thus, it might be expected that the net concentration factor for iodine-131 would be somewhat less than that for calcium, considering this additional removal process. The extent to which the iodine-131 concentration factor is less than that for calcium would depend on the mean residence time for the water in the basins compared to iodine-13 l's radioactive half-life - the greater the ratio of the mean residence time to the half-life, the smaller the concentration factor. A mean residence time for water in the basins is expected to be about two days. This is only about one-fourth of the approximately eight-day half-life of iodine-131. Thus, radioactive decay would not be expected to reduce the concentration factor for iodine-131 by a large amount.

Therefore, the difference between the 2008 mean iodine-131 actiyity of about 0.74 pCi/l in the CTBD and the 2008 mean iodine-131 activity for die control location of 0.34 pCi/l is most probably the result of concentration in the basins.

Additional support for this assumption is that iodine-131 was not reported in water discharged from the SSES to the Susquehanna River during 2008.

Surface Water Tritium Monthly samples from all surface water locations were analyzed for concentrations of tritium activity (Table 1-2 and Table 6). Tritium was detected in the indicator location above MDC. The 2008 indicator values ranged from -28.3 to 10,800 pCi/l compared to

-147 to 15,300 for 2007. Comparison of the 2008 meafn tritium activity of 882 pCi/1 for all indicator locations to the average of the annual preoperational control mean of 171 pCi/I indicates a contribution of tritium activity from the SSES.

Refer to Figure 10 which trends tritium activity levels separately for surface water indicator and control locations from 1972 through 2008.

The much higher levels of tritium observed in the CTBD line (location 2S7), when averaged with the low levels from the downstream location 2008 Radiological Environmental Monitoring Report 26 2008 Radiological Envirohinental Monitoring Report 26

Aquatic Pathway Monitoring 6S5 sample analysis results distort the real environmental picture. The mean tritium activity level from indicator location 6S5 for 2008 was 48.0 pCi/liter, which is greater than the mean tritium activity of 38.4 pCi/I for the control location and is below the annual preoperational control mean of 171 pCi/l.

Tritium activity levels reported for 2S7 are from the discharge line prior to dilution in the river. The highest quarterly average tritium activity reported at 2S7 during 2008 was approximately 3,852 pCi/liter for the second quarter. This is well below the NRC Reporting Levels for quarterly average activity levels of 20,000 pCi/liter when a drinking water pathway exists or 30,000 pCi/liter when no drinking water pathway exists.

The tritium activity reported in the CTBD line from location 2S7 is attributable to the SSES. Refer to the "Dose from the Aquatic Pathway" discussion at the end of this section for additional information on the projected dose to the population from tritium and other radionuclides in the aquatic pathway attributable to the SSES.

No gamma-emitting radionuclides were detected in surface water samples above MDC, with the exception of iodine-131, K-40 and Th-228.

Drinking Water Drinking water was monitored during 2008 at the Danville Water Company's facility 26 miles WSW of the SSES on the Susquehanna River at location 12112.

There are no known drinking water supplies in Pennsylvania on the Susquehanna River upstream of the SSES and therefore no drinking water control monitoring locations. Danville drinking water analysis results may be compared to the results for surface water control monitoring locations.

Aquatic Pathway Monitoring Dose from the Aquatic Pathway Tritium Was the only radionuclide identified in 2008 by the SSES REMP in the aquatic pathway that was attributable to SSES operation and also included in the pathway to man.

The total tritium activity released from the SSES forthe year was estimated based on REMP monitoring results and used in projecting maximum doses to the public. The annual mean activity level of tritium in the CTBD line (monitoring location 2S7) for 2008 was 2,305 pCi/l. The annual mean activity of tritium for control location 6S6 was 38.4 pCi/l. For the purpose of performing-the dose calculation, tritium was assumed to be present continuously in the CTBD line throughout 2008 at a level equivalent to the annual mean activity of 2,305 pCi/1, The annual mean flow rate for the CTBD line was 9,653 gpm. Using theproper unit conversions and multiplying 9,653 gpm times 2,305 pCi/l yields a value of 44 curies for the estimate of tritium released from SSES during 2008. This estimate is 11 curies more than the 33 curies of tritium determined by effluent monitoring that was released to the river by the SSES in 2008.

Given the total tritium aictivity released, the maximum whole-body and organ doses to hypothetical exposed individuals in four age groups (adult, teenager, child, and infant) were determined according to the methodology of the Offsite Dose Calculation Manual using the RETDAS computer program. This is in accordance with SSES Technical Requirement 3.11.4.1.3.

The maximum dose obtained from the ingestion of tritium was estimated at the nearest downriver municipal water supplier via the drinking water pathway and near the outfall of the SSES discharge to the Susquehanna River via the fish pathway. The maximum whole body and organ doses (child) were each calculated as 7.60E-4 mrem as reported in the 2008 Radioactive Effluent Release Report.

Atmospheric Pathway Monitoring ATMOSPHERIC PATHWAY MQNITORING INTRODUCTION Sampling and Analysis Atmospheric monitoring by the SSES REMP involves the sampling and analysis of air. Because the air is the first medium that SSES vent releases enter in the pathway to man, it is fundamental that it be monitored.

Mechanisms do exist for the, transport of airborne contaminants to other media and their concentration in them. For example, airborne contaminants may move to the terrestrial environment and concentrate in milk. Concentrations of radionuclides can make the sampling and analysis of media like milk more sensitive approaches for the detection of radionuclides, such as iodine-131, in the pathway to man than the monitoring of air directly. (PPL also samples milk; refer to the Terrestrial Pathway Monitoring section of this report.)

Nevertheless, the sensitivity of air monitoring can be optimflized by the proper selection of sampling techniques and the choice of the proper types of analyses for the collected samples.

Scope Air samples were collected on particulate filters and charcoal cartridges at indicator locations 3S2, 12S1, 13S6 and 12E1, and control locations 6G1 and 8G1.

Air The SSES REMP monitored the air at four indicator locations and two control locations during 2008. The SSES Technical Requirements require monitoring at only a total. of five sites.

Monitoring is required at three locations at the SSES site boundary in different sectors with the greatest predicted sensitivities for the detection of SSES releases (3S2, 12SI, 13S6). Monitoring must be performed at the community in the vicinity of the SSES with the greatest predicted. sensitivity (12E1). A control location that is expected to be unaffected by any routine SSES releases must be monitored (6G1, 8G1).

Airborne particulates were collected on glass fiber filters using low volume (typically 2.0 to 2.5 cfm sampling rates) air samplers that run continuously. Air iodine samples were collected on charcoal cartridges, placed downstream of the particulate filters.

Particulate filters and charcoal cartridges were exchanged weekly at the air monitoring sites. Sampling times were recorded on elapsed-time meters.

Air sample volumes for particulate filters and charcoal cartridges were measured with dry-gas meters.

Air filters were analyzed weekly for gross beta activity, then composited quarterly and analyzed for the activities of gamma-emitting radionuclides. The charcoal cartridges were analyzed weekly for iodine-Ij 1.

Appendix I, Table 1-8 pages 1-15 and 1-16, shows specific sample results of gross beta analyses for air particulate filters.

Air Particulate Gross Beta Weekly samples from all air particulate filter locations were analyzed for concentrations of gross beta activity (Table 1-8). Gross beta activity was observed at all locations above MDC for 2008. The 2008 indicator values ranged from 6.OOE-3 to 33.4E-3 pCi/m 3, compared to 5.30E-3 to 32E-3 pCi/m 3 for 2007. The 2008 mean gross beta activity of 14.9E-3 pCi/m 3for all indicator locations compared to the average of the annual preoperational control mean of 62E-3 pCi/m3. indicates activity detected below the preoperational control. In addition, a comparison of the 2008 indicator mean of 14.9E-3 pCi/m 3 with the 2008 control locations mean of 13.4E-3 pCi/m 3 indicates no appreciable effects from the operation of SSES.

Gross beta activity is normally measured at levels in excess of the analysis MDCs on the fiber filters. The highest gross beta activity levels that have been measured during the operational period of the SSES were obtained in 1986 following the Chernobyl accident in the former Soviet Union.

Note that prior to SSES operation, before 1982, the unusually high gross beta activities were generally attributable to fallout from atmospheric nuclear weapons tests. Typical gross beta activities measured on air particulate filters are the result of naturally occurring radionuclides associated with dust particles suspended in the sampled air. They are thus terrestrial in origin.

The SSES Technical Requirements Manual requires radionuclide analysis if any weekly gross beta, result was greater than ten times the most recent years annual mean gross beta value for all air particulate sample control locations.

This condition did not occur during 2008.

Air Particulate Gamma Spectroscopic Quarterly gamma spectroscopic measurements of composited filters often show the naturally occurring radionuclide beryllium-7. Occasionally, other naturally occurring radionuclides, potassium-40, radium-226, actinium-228, and thorium-228 are also observed.

Atmospheric Pathway Monitoring Beryllium-7 is cosmogenic in origin, being produced by the interaction of cosmic radiation with the earth's atmosphere. The other four gamma-emitting radionuclides originate from soil and rock.

Beryllium-7 was measured above analysis MDCs for all quarterly composite, samples in 2008. The 2008 indicator and control means, for beryllium-7 activity were 129E-3 and 1 19E-3 pCi/i 3,m respectively.,

Berylliuim-7 activity levels for each 2008 calendar quarter at each monitoring location are presented in Table I-9 of Appendix I. Comparisons of 2008 beryllium-7 analysis results with previous years may be found in Table H i4 of Appendix H.

No other gamma-emitting radionuclides were reported for air in 2008.

SBeryllium-7 is not attributable to SSES operation.

Air odine Iodine-i 3.1 has been detected infrequently from 976., when it, was first monitored, through 2008. Since operati6n of the SSES began in 1982, iodine' 131 has only been positively detected in air samples in 1986 due to the Chernobyl accident. No iodine-131 was reported for the2008 air monitoring results.

Terrestrial Pathway Monitorinz TERESRIAL PATHA MONITOING' INTRODUCTION Soil and milk were monitored in the Terrestrial Pathway in 2008.

Soil can be a great accumulator of man-made radionuclides that enter it. The extent of the accumulation in the soil depends of course on the amount of the radionuclides reaching it, but it also depends on the chemical nature of those radionuclides and the particular characteristics of the soil. For example, the element cesium, and, therefore, Cesium-137 can be bound Very tightly to clay in soils. The amount of clay in soil can vary greatly from one location to another. In clay soils, cesium-137 may move very slowly and also may be taken up very slowly in plants as they absorb soil moisture.

Any medium, such as soil, that tends to accumulate radioactive materials can also provide more sensitivity for radionfuclide detection in the environment than those media that don't. Such a medium facilitates the early identification of radionuclides in the environment, as well as awareness of changes that subsequently may occur in the environmental levels of the identified radionuclides.

The SSES REMP samples soil near two of the six REMP air-sampling stations.

The purpose for soil sampling near the air sampling sites is to make it easier to correlate air sampling results with soil sampling results if any SSES related radioactive material were found in either medium. Sampling is performed at different depths near the surface to help provide information on how recently certain radioactive materials may have entered the soil. Sampling at more than one depth also may help ensure the detection of materials that move relatively quickly through the soil.

Such quick-moving materials may have already passed through the topmost layer of soil at the time of Sampling.

Milk was sampled at four locations in 2008. SSES Technical Requirements require that the SSES REMP sample milk at the three most sensitive monitoring locations near the SSES and one control location distant from the SSES.

No requirement exists for the SSES REMP to monitor soil. All monitoring of the terrestrial pathway that is conducted by the SSES REMP in addition to milk (and broad leaf vegetation in certain cases when milk sampling not performed) is voluntary and reflects PPL's willingness to exceed regulatory requirements to ensure that the public and the environment are protected.

Scope Soil Soil was sampled in September 2008 in accordance with its scheduled annual sampling frequency, at the following two REMP air sampling locations: 12S1 (indicator) and 8G1 (control).

Several soil plugs were taken at selected spots at each monitoring location. The 2008 Radiological Environmental Monitoring Report 37 2008 Radiological Efivironihental Monitoring Report, 37

Terrestrial Pathway Monitorinz plugs were separated into "top" (0-2 inches) and "bottom" (2-6 inches) segments. Each set of top and bottom segments was composited to yield 2 soil samples from each location for analysis.

Since there are two monitoring locations, a total of 4 soil samples were analyzed in 2008.

Milk Milk was sampled at least Monthly at the following locations in 2008: 10D2 (5E2 replaced 10D2 on 4/7/08), 10D3 13E3 and 1OG1.

Milk was sampled bi-weekly from April through October when cows were more likely to be on pasture and monthly at other times. Locations 10D2, 5E2, 10D3, and 13E3 are believed to be the most sensitive indicator sites available for the detection of radionuclides released from the SSES. Location 10G1 is the control location.

Sample Preservation and Analysis All media in the terrestrial pathway are analyzed for the activities of gamma-emitting radionuclides using gamma spectroscopy. The other analysis that is routinely performed is the radiochemical analysis for iodine-131 in milk.

Monitoring Results Refer to the following for results of the terrestrial pathway analyses for 2008:

Figure 13 trends ibdine-131 activities separately for milk indicator and control locations from 1977 through 2008.

" Appendix G, Table G pages G-12 through G-14, shows a summary of the 2008 terrestrial monitoring results for milk and soil.

Appendix H, Tables H-15 through H-19, pages H-6 and H-7, shows comparisons of terrestrial pathway monitoring results against past years' data.

" Appendix I, Tables 1-10 and I-11 pages 1-18 through 1-21, shows results of specific sample analyses for terrestrial pathway media.

The only man-made radionuclides normally expected at levels in excess of analysis MDCs in the terrestrial pathway are strontium-90 and cesium-137. Both of these radionuclides are present in the environment as a residual from previous atmospheric nuclear weapons testing. Strontium-90 analyses are not now routinely performed for any media samples in the terrestrial pathway. Strbntium-90 activity would be expected to be found in milk. SSES Technical Requirements do not require that milk be analyzed for strontium-90.

Strontium-90 analyses may be performed at any time if the results of other milk analyses would show detectable levels of fission product activity, such as 1-131, which might suggest the SSES as the source.

Cesium-137 normally has been measured in excess of analysis MDCs in most soil samples.

38 2008 Radiological Environmental Monitoring Report

Terrestrial Pathway Monitoring Certain naturally occurring radionuclides are also routinely found above analysis MDCs interrestrial pathway media. Potassium-40, a primordial and very long-lived radionuclide, which is terrestrial in origin, is observed in all terrestrial pathway media. Other naturally occurring radionuclides often observed in soil are thorium-228 and radium-226.

Soil Annual samples from the 12S1 and 8Gi soil locations were analyzed for concentrations of gamma emitting nuclides (Table I-11). The following gamma-emitting radionuclides are routinely measured in soil at levels exceeding analysis MDCs: naturally occurring potassium-40, radium -226, actinium-228, thorium-228 and man-made cesium-!37. The 2008 analysis results were similar to those for previous years. No other gamma-emitting radionuclides were reported at levels above analysis MDCs.

The 2008 means for indicator and control location potassium-40 activity were 11,500pCi/kg and 11,300 pCi/kg,

.respectively. This is not the result of SSES operation because the potassium-40 is naturally occurring.

The 2008 means for indicator and control location radium-226 activity were 1,430 pCi/kg and 2,050 pCi/kg, respectively. Radium-226 in soil is not the result of SSES operation because it is naturally occurring.

The 2008 means for indicator and control actinium-228 activity were 864 pCi/kg and 958 pCi/kg, respectively.

The 2008 means for indicator and control location thorium-228 activity were 858 pCi/kg and 711 pCi/kg, respectively. Thorium-228 in soil is not the result of SSES ope ration because it is naturally occurring.

The 2008 means for indicator and control location cesium-137 activity were 75 pCi/kg and 166 pCi/kg, respectively. The 2008 indicator values ranged from 60 to 89 pCi/kg, compared to 46 to 73 pCi/kg for 2007. Typically cesium-137 has been observed in preoperational control samples at 200 to 1200 pCi/kg as well as prior operational years in the 70 to 1200 pCi/kg range.

The measured activities of cesium-137 were also detected in previous years at expected levels due to residual fall out from past atmospheric weapons testing and the Chernobyl event. As a general rule, it takes approximately ten half lives for a radionuclide to decay to non-detectable levels. C.esium-137 with its 30 year half life (300 years to decay to non-detectable) would still be present in samples in 2008. Cesium-137 in soil, although man-made, is not from Susquehanna station operations.

Milk Semi-monthly or monthly samples from all milk locations were analyzed for concentrations of iodine-131 and other gamma-emitting nuclide activity (Table I-10). No detectable iodine-131 activity above MDC was observed at any location for 2008. The 2008 indicator values ranged from -0.56 to 0.56 pCi/l, compared to -0.48 to 0.58 pCi/1 for 2007. Iodine-131 has been chemically separated in milk samples and counted routinely since 1977. Refer to Figure 13 which trends iodine-131 activity in milk 2008 Radiological Environmental Monitoring Report 39

Terrestrial Pathway Monitoring for indicator and control locations from 1977 through 2008.

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 Chemobyl incident.

With the exception of the naturally occurring potassium-40, actinium-228, and thorium-228 no gamma-emitting radionuclides were measured in excess of analysis MDCs in 2008. The 2008 means for indicator and control location potassium-40 activity were 1,290 pCi/liter and 1,300 pCi/liter, respectively. The potassium-40 activity in milk is not attributable to SSES operation because it is naturally occurring.

Ground.Water Monitoring K

jý. GROUN:D WATER MOIORING..

INTRODUCTION Scope Normal operation of the SSES does not involve the release of radioactive material to ground water directly, or indirectly through the ground. As a result, there are no effluent monitoring data to compare with REMP ground water monitoring results. Ground water could conceivablybecome contaminated by leakage or spills from the plant or by the washout or deposition of radioactive material that might be airborne. If deposited on the ground, precipitation/soil moisture could aid in the movement of radioactive materials through the ground to water that could conceivably be pumped for drinking purposes. No use of ground water for irrigation near the SSES has been identified.

Primary release paths for recent groundwater contamination events at other nuclear facilities have been: 1) spent fuel pool. leakage; 2) leaks from liquid radwaste discharge lines and; 3) leaks from cooling tower blowdown lines. The physical location of the spent fuel pools at Susquehanna and the fuel p0ol leakage collection system make it highly unlikely that the fuel Pools Would be a radiological contamination source for groundwater. Leaks from the liquid radwaste discharge line or the cooling tower blowdown line could impact ground water, but to date, there has been no indication of any radiological impacts on groundwater due to station operations.

Ground water in the SSES vicinity was sampled quarterly at 10 indicator locations (2S2, 4S4, 6S10, 11S2, 1IS3, 4S8, 4S9, 8S4, 7S10 and 13S7) and one control location (12F3) during 2008.

With the exception of location 4S4, untreated ground water was sampled.

Untreated means that the water has not undergone afny processing such as filtration, chlorination, or softening. At location 4S4, the SSES: Learning Center, Well water actually is obtained from on-site and piped to the Learning Center after treatment. This treatment would not affect tritium analysis. This sampling is performed as a check to ensure that water has not been radioactively contaminated. Sampling is performed at the Leanig Center to facilitate the sample collection process.

Sample Preservation &

Analysis Ground water samples were analyzed for gamma-emitting radionuclide and tritium activities. Gamma spectrometric analyses of ground water began in 1979 and tritium analyses in 1972, both prior to SSES operation.

Ground Water Monitorini!

Monitoring Results Tritium activity levels in ground water have typically been observed to be lower than in surface water. A noticeable decline occurred between 1992 and 1993. Fewer measurements were above the analysis sensitivities after 1993.

Gamma-emitting radionuclides in excess of MDCs have been found in only a few samples in all the years that these analyses have been performed.

The naturally occurring radionuclides potassium-40 and thorium-228 have been measured above their MDCs occasionally in ground water.

Potassium-40 was reported in 1.979, 1981, 1985, 1991, 1992, 1993, and 1997. Thorium-228 was found in 1985 and 1986. The man-made radionuclide cesium-13.7 has been detected only occasionally since 1979. Its presence has always been attributed to residual fallout from previo'us atmospheric nuclear weapons tests.

Results for the 2008 specific ground water sample analyses may be found in Table I"7 of Appendix I. A summary of the 2008 ground water monitoring data may be located in Appendix G, pages G-6 and G77. Comparisons of 2008 monitoring results for tritium with those of past years may be found in Table H 20 of Appendix H.

In 2008, tritium was measured above MDC, in eleven samples at indicator locations 13S7, 1S3, 4S8, 8S4, 4S9, and 7S10. The activities were slightly above the detection limit. The 2008 indicator values ranged from -19.7 to 381 pCi/l, compared to 11.3 to 146 pCi/l for 2007. The 2008 mean tritium activity levels for indicator and control monitoring locations were 136 and 25.9 pCi/1, respectively.

The only REMP monitored pathway where tritium has been identified as a result of station operations is in the surface water pathway (Susquehanna River) downstream of the site and at some groundwater monitoring locations (perimeter drains, MW-1I and MW-2 due to precipitation washout from routine airborne effluent releases.

Monitoring Wells and Precipitation An expanded groundwater-monitoring network was initiated for the Station as part of a site-wide hydrogeological investigation in accordance with the Nuclear Energy.Institute (NEI)

Groundwater Protection Initiative (GPI).

In 2008, four additional groundwater monitoring wells were installed atthe PPL Susquehanna Site. The additional groundwater monitoring wells are sampled a's part of the Radiological Environmental Monitoring Program to regularly assess groundwater quality and provides early detection of any inadvertent leaks or spills of radioactive materials that could reach groundwater.

Groundwater is sampled quarterly and analyzed for tritium and gamma activity. Additionally, precipitation sampling was initiated in 2007and collected monthly and analyzed for tritium activity to assess the influence of station airborne tritium emissions on groundwater tritium activities.

Precipitation washout monitoring data is not used in dose calculations; however, the data does give a gross indication of tritium concentrations which makes its way into surface water and soil where it eventually seeps into shallow groundwater. The average annual tritium concentrations in precipitation, perimeter drain manholes, groundwater monitoring wells, and surface water results are detailed below in Table GW 1 and graphically in Figure 14.

Ground Water Monitoring Precipitation will invariably become groundwater via infiltration through soil and into groundwater. The average tritium concentration in precipitation on-site was 370 pCi/1 in 2007 and 2008. In 2008, the tritium in rainwater samples ranged from 24 to 1490 pCi/1. 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. Variations in tritium concentrations between precipitation and the Perimeter Drain System are not statistically different in 2007 and 2008 as indicated by 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, MW-1, and MW-2 have tritium concentrations that are elevated relative to background. 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. Variations between background and monitoring wells 3, 4, 5, 6,8A, 9 and 10 are statistically insignificant having negligible groundwater quality impact.

The pre-operational groundwater background (12F3 control) from 1980-81 was approximately 120 pCi/1 and is located 5.2 miles WSW of the Susquehanna site.

TLD Locations for the SSES Radiological Environmental Monitoring Program - 2008 a)

All distances from the SSES to monitoring locations are measured from the standby gas treatment vent at 44200/N34117 (Pa. Grid System). The location codes are based on both distance and direction from the SSES. The letters in the location codes indicate if the monitoring locations are on site (within the site boundary) or; if they are not on site, the approximate distances of the locations from the SSES as described below:

S - on site E 5 miles A- <1 mile F-5-10miles B 2 miles G 20 miles C 3 miles H -

>20 miles D 4 miles

. Special interest areas (other than controls)

- - Control TLDs The numbers preceding the letters in the location codes provide the directions of the monitoring locations from the SSES by indicating the sectors in which they are located. A total of 16 sectors (numbered 1 through 16) equally divide an imaginary circle on a map of the SSES and its vicinity, with the SSES at the center of the circle. The middle of sector 1 is directed due north (N). Moving clockwise from sector 1, the sector immediately adjacent to sector 1 is sector 2, the middle of which is directed due north, northeast (NNE). Continuing to move clockwise, the sector numbers increase to 16, which is the north, northwest sector.

The numbers following the letters in the location codes are used to differentiate sampling locations found in the same sectors at approximately the same distances from the SSES.

Sampling Locations for the SSES Radiological Environmental Monitoring Program - 2008 a)

All distances from the SSES to monitoring locations are measured from the standby gas treatment vent at 44200/N341 17 (Pa. Grid System). The location codes are based on both distance and direction from the SSES. The letters in the location codes indicate if the monitoring locations are on site (within the site boundary) or, if they are not on site, the approximate distances of the locations from the SSES as described below:

S - on site E 5 miles A - <1 mile F 10 miles B 2 miles G 20 miles C 3 miles H - >20 miles D 4 miles

- Control locations The numbers preceding the letters in the location codes provide the directions of the monitoring locations from the SSES by indicating the sectors in which they are located. A total of 16 sectors (numbered 1 through 16) equally divide an imaginary circle on a map of the SSES and its vicinity, With the SSES at the center of the circle. The middle of sector 1 is directed due north (N). Moving clockwise from sector 1, the sector immediately adjacent to sector 1 is sector 2, the middle of which is directed due north, northeast (NNE). Continuing to move clockwise, the sector numbers increase to 16, which is the north, northwest sector.

The numbers following the letters in the location codes are used to differentiate sampling locations found in the same sectors at approximately the same distances from the SSES.

b)

No actual location is indicated since fish are sampled from the Susquehanna River at or below the SSES discharge diffuser.

c)

No permanent locations exist; samples are taken based on availability.

Consequently, it is not necessary to assign a number following the letter in the location code.

Ampendix D 2008 LAND USE CENSUS RESULTS Ecology III, Inc. conducted a Land Use Survey, during the 2008 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 2007 TO 2008 Since the 2007 census, there were no changes in the nearest residence, three changes in the nearest garden, and one less dairy farm within the 50 mile radius.

Residence Census:

The residence census was conducted from 18 July through 30 September 2008.

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 (D.

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

There were no changes from the 2007 census.

Garden Census:

The garden census was conducted from 18 July through 29 September 2008. Distances of the nearest gardens from the Susquehanna SES in the 16 different sectors ranged

'from 0.6 miles (T. Scholl, Sector 7) to 4.5 miles (R. Reider, Sector 15), with an average of 2.2 miles.

Changes from the 2007 census included: Sector 5 -W. Daily replaced L. Kozlowski and W. Witts (no garden), Sector 6-B. Smith replaced L. Travelpiece (no garden), Sector 15

-R. Reider replaced D. Goff (no garden).

Dairy Animal Census:

Identified six dairy animal sites in the dairy farm census conducted from 14 through 21 July 2008. 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.

Changes from 2007 census included one dairy farm that ceased operations between 2007 and 2008 census: R. Ryman (location 10D2) stopped milking operations and sold his dairy cows in April 2008.

Irrigation Three farms irrigated crops using Susquehanna River water downriver from the Susquehanna SES in 2008: Zehner Farm (location 1 IDI, 3.3 miles SW) - irrigated 2008 Radiological Environmental Monitoring Report D-2

Appendix D pumpkins. Chapin Farm - Drake Field (location 11F2, 5.5 miles SW) - irrigated green beans, and Lupini Farm - Mifflinville Field (12F7, 8.3 miles WSW) - irrigated potatoes. Samples of these crops were collected between 3 and 22 September 2008. A control sample of irrigated potatoes upriver from the Susquehanna SES discharge was also collected on 22 September from the Chapin Farm - Susquehanna Project East Side

-Parcel 25 (location 5S 11, 1.1 miles E).

No other farms irrigated because soil moisture was sufficient for the crops. 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 0f 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 0

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 xeek, 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 2008 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 inportance 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 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 tobe quantitatively determined.

Results reported as less than (<) in these tables are below themminimum 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 gos s 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 91.251x, where x is-the actual duration inmdays of the period.

(3). Uncertainties~for individual monitoring locationresults are two standard'deviations of-the elemental doses of six calcium elements from thetwo TLDs assigned to each monitoring location, representing the variability, between the elemental doses of each of the: six TLD elements.

(4) -No measurement could be made at thislocation because the TLDs were lost, -stolen,*damaged or notexchanged. Refer to Appendix A of the Annual Radiological Environmental Operating Report for an explanation of program exceptions to REMP.

APPENDIX J 2008 Radiological Environmental Monitoring Report J-1

Appendix J The data in the tables that follow show how well Teledyne Brown Engineering Environmental Services (TJBE) 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 theDOE (Table J4)

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.

Appendix J 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-I through J-4. Discussions relevant to these commerit numbers follow the presentations of the data, as applicable.
