SUMMARY

AND CONCLUSIONS Radiolo*,ical Dose Impact This report on the Radiological Environmental Monitoring Program covers the year 2007.

During that period, 1211 analyses were performed on 927 samples at 32 sampling locations. Additionally, 228 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.

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 0.0321 mrem for all of 2007. This dose represents approximately 0.13% 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 13 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 2007.

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 0.0012 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 sediment 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 above the detection limit. The 2007 indicator mean tritium activity level is lower than the range for preoperational years. No fission or activation products were detected.

Soil samples were analyzed for concentrations of gamma emitting nuclides. Cesium-137 was observed in soil 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 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 were consistent with those detected in previous years. No fission or activation products were detected.

Pumpkins, soybeans, green beans, potatoes and rye 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. Concentrations of naturally occurring K-40 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. Three tritium samples were measured above analysis MDC in 2007. The activity was slightly 2007 Radiological Environmental Monitoring Report 3

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 2007.

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 0.0012 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.

This assumption is 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

-j Radiological 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 Elect ric 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.

Introduction In 2007, the SSES REMP collected 927 samples at 32 locations and performed 1,211 analyses. In addition, the REMP monitors ambient radiation levels using thermoluminescent dosimeters (TLDs) at 57 indicator and control locations, resulting in 228 radiation level measurements in 2007. 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 nuclear 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-137 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 Monitorine I

AMBIENT 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 measuring the intensity of the light that they emit. The intensity of the emitted light is proportional to 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, radwaste 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 placement of 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 permits 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).

2007 Environmental Radiological Monitoring Report 17 2007 Environmental Radiological Monitoring Report 17

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

During 2007, the SSES REMP had 46 indicator, 6 special interest and 5 control TLD locations. Refer to Table C 1 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, 3E1, 4E2, 5E2, 6E1, 7E1, 8D3, 9D4, IOD1, 11El, 12D2, 13E4, 14D1, 15F1 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 3.21 E-02 mrem for 2007 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 0.13% 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 AUATIC PATHWAY MONITRNG INTRODUCTION In 2007 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 2007 looked at farms within 10 miles downstream of the SSES. The Zehner Farm (11 DI-field east of Nescopeck) irrigated pumpkins, soybeans and rye in August 2007, using Susquehanna River water. Additionally the Lupini Farm (11D2-Route 93 field) irrigated green beans and potatoes in August 2007 using Susquehanna River water. No other fields within 10 miles downriver of Susquehanna SES were irrigated in 2007.

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 can receive 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 2007 Radiological Environmental Monitoring Report 21

Aquatic Pathway Monitoring 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 2007.

Sampling also took place at the following additional indicator locations:

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

Drinking Water Drinking water samples were collected at location 12H2, the Danville Municipal Water Authority's treatment facility on the Susquehanna River, in 2007. 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 2007, 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 D1 and 11D2.

These locations were irrigated with Susquehanna River water in 2007. 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 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.

Aquatic Pathway Monitorine 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, LTAW and 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, soybeans, rye, 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 1-131 activity each month. Drinking water samples were analyzed monthly for beta, 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.

23 2007 Radiological Environmental Monitoring Report

Aquatic Pathway Monitorine 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 entering 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 by the returning noncontaminated 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 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 2007 was approximately 7,210,000 gpm. The CTBD average flow during 2007 was 9,180 gpm.

Based on the average river flow and the average CTBD flow during 2007, 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 2007 Radiological Environmental Monitoring Report 24 2007 Radiological Environmental Monitoring Report 24

Aquatic Pathway Monitoring 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 2007 indicator values range from

-0.109 to 1.66 pCi/1 compared to -0.482 to 1.21 for 2006. Comparison of the 2007 mean iodine-131 activity of 0.66 pCi/l for all indicator locations to the average of the annual control mean of 0.36 pCi!l for pre-operational years suggests activity detected slightly above the preoperational control.

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 SSES 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 2007 was 0.90 pCi/l compared to the control mean of 0.45 pCi/l for 2007. The 2007 mean iodine-131 activity of 0.42 pCi/l at the indicator 6S5 (Outfall Area) was slightly lower than the mean iodine-131 activity of 0.45 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 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 2007 mean iodine-131 activity level for the 25 2007 Radiological Environmental Monitoring Report 25 2007 Radiological Environmental Monitoring Report

Aquatic Pathway Monitoring control samples from the Susquehanna River, a mean concentration of 1.80 pCi/liter for iodine-131 in the basin water and the water being discharged from the basins would be expected. The actual 2007 mean of 0.90 pCi/l for the CTBD mean is 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-131'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 2007 mean iodine-131 activity of about 0.90 pCi/l in the CTBD and the 2007 mean iodine-131 activity for the control location of 0.45 pCi/I 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 2007.

Surface Water Tritium Monthly samples from all surface water locations were analyzed for concentrations of tritium activity (Table 1-2 and Table G). Tritium was detected in the indicator location above MDC. The 2007 indicator values ranged from -147 to 15,300 pCi/I compared to

-45 to 11,900 for 2006. Comparison of the 2007 mean tritium activity of 1,400 pCi!l 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 2007.

The much higher levels of tritium observed in the CTBD line (location 2S7), when averaged with the low levels from the downstream location 6S5 sample analysis results distort the real environmental picture. The mean tritium activity level from indicator location 6S5 for 2007 was 65.0 pCilliter, which is greater than the mean tritium activity of 8.7 pCi/I for the control location and is within the range of prior operational and preoperational periods.

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 2007 was approximately 6,692 pCi!liter for the fourth quarter. This is well below the NRC Reporting Levels for quarterly average activity levels of 20,000 pCi/liter when a drinking water 2007 Radiological Environmental Monitoring Report 26

Aquatic Pathway Monitoring 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 2007 at the Danville Water Company's facility 26 miles WSW of the SSES on the Susquehanna River at location 12H2.

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.

Refer to the following for results of surface water analyses for 2007:

Appendix I, Table 1-4 shows specific results of gross beta, tritium and gamma spectroscopic analyses of drinking water Drinking Water Gross Beta Monthly samples from the 12H2 drinking water location were analyzed for concentrations of gross beta activity (Table 1-4). Beta activity was detected in the 12H2 location above MDC for 2007. The 2007 values ranged from 0.93 to 5.29 pCi/l compared to 0.73 to 5.84 for 2006.

Gross beta activity has been monitored in drinking water since 1977. Gross beta activity is typically measured at levels exceeding the MDCs in drinking water samples. The 2007 mean gross beta activity of 2.5 pCi/l is above the mean gross beta activity of 2.4 for 2006 but is within the range of the preoperational (1977-81) values of 2.2 to 3.2 pC/1.

Drinking Water Tritium Monthly samples from the 12H2 drinking water location were analyzed for concentrations of tritium activity (Table 1-4). Tritium activity was not detected above MDC in any of the 14 drinking water samples in 2007. The 2007 values ranged from -97.8 to 115 pCi/l compared to -132 to 62.5 for 2006.

Fish Gamma Spectroscopic Semi-annual samples from the indicator (IND) and control (2H) fish locations were analyzed for concentrations of gamma activity (Table 1-5).

Four species of fish were sampled at each of one indicator location and one control location on the Susquehanna River in the spring 2007 and again in fall 2007. The species included the following: smallmouth bass, channel catfish, and shorthead redhorse. In addition, one largemouth bass was sampled from PPL's LTAW in October 2007. A total of 13 fish were collected and analyzed.

The only gamma-emitting radionuclide reported in excess of analysis MDCs in fish during 2007 was naturally occurring potassium-40. The 2007 indicator values ranged from 3,080 to 4,100 pCi/kg compared to 2,640 to 4,250 for 2006. The 2007 indicator and control means for the activity levels of potassium-40 in fish were 3,427 pCi/kg and 2,713 pCi/kg, respectively.

Naturally occurring potassium-40 in fish is not attributable to the liquid discharges from the SSES to the Susquehanna River.

Sediment Gamma Spectroscopic Semi-annual samples from all sediment locations were analyzed for concentrations of gamma activity (Table 1-6).

Aquatic Pathway Monitoring samples in 2007. The naturally occurring radionuclides in sediment are not attributable to the liquid discharges from the SSES to the Susquehanna River.

Cesium-137 was measured at activity levels slightly above analysis MDCs in 1 of 6 shoreline sample analyses in 2007. The 2007 indicator and control means for cesium-137 activity in sediment were 19.3 pCi/kg and 64 pCi/kg, respectively. The 2007 indicator

-and control means are lower than the respective means in 2006. These samples are within the annual mean for all prior operational as well as preoperational years of station operations. Typically cesium-137 has been observed in previous operational years in the 20 to 210 pCi/kg range and reported attributable to fall out from past weapons testing. Station operations does not typically release cesium-137 in liquid effluents; however, 7.6 E-7 Curies was reported as being released in liquid effluents during the first quarter of 2007. No Cs-137 was identified above analysis MDCs at any indicator locations in 2007.

Fruits and Vegetables Refer to the following for results of fruits and vegetables for SSES:

Appendix G, Table G pages G-14 and G-15, shows a summary of the 2007 fruits and vegetables.

Appendix I, Table 1-12 page 1-22, shows specific gamma spectroscopic analysis of fruit/vegetable samples.

Fruit /Vegetable Gamma Spectroscopic Pumpkin, soybeans and rye samples were collected from location 1 ID1.

Green beans and potato samples were collected from location 1 1D2 and analyzed for concentrations of gamma emitting nuclide activity (Table 1-12).

Potassium-40 and thorium-228 were the only gamma-emitting radionuclides measured in fruits and vegetables at an activity level above MDC during 2007.

The average potassium-40 concentration for the indicator samples was 5398 pCi/kg. The 2007 indicator values ranged from 2350 to 15,000 pCi/kg compared to 1820 to 16,600 pCi/kg for 2006.

Potassium-40 and/or thorium-228 in fruits and vegetables is not attributable to SSES operation because they are naturally occurring radionuclides.

Dose from the Aquatic Pathway Tritium was the only radionuclide identified in 2007 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 for the 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 2007 was 3,582 pCi/l. The annual mean activity of tritium for control location 6S6 was 8.7 pCi/l. For the purpose of performing the dose calculation, tritium 29 2007 Radiological Environmental Monitoring Report 29 2007 Radiological Environmental Monitoring Repo rt

Aquatic Pathway Monitoring was assumed to be present continuously in the CTBD line throughout 2007 at a level equivalent to the annual mean activity of 3,582 pCi/l. The annual mean flow rate for the CTBD line was 9,180 gpm. Using the proper unit conversions and multiplying 9,180 gpm times 3,582 pCi/l yields a value of 65.7 curies for the estimate of tritium released from SSES during 2007. This estimate is 4.3 curies less than the 70 curies of tritium determined by effluent monitoring that was released to the river by the SSES in 2007.

Given the total tritium activity 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 0.0012 mrem.

Atmospheric Pathway Monitoring-ATMOSP.HE-RICy-PA',THWA MNTORIN~

INTRODUCTION 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-13 1, 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 optimized 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 12El, and control locations 6G1 and 8G1.

Sampling and Analysis Air The SSES REMP monitored the air at four indicator locations and two control locations during 2007. 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, 12S1, 13S6). Monitoring must be performed at the community in the vicinity of the SSES with the greatest predicted sensitivity (12El). 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-131.

Appendix H, Tables H 13 and 14 page H-5, shows comparisons of gross beta and Beryllium-7 monitoring results against past years' data.

" Appendix I, Table 1-8 pages 1-14 and 1-15, 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 2007. The 2007 indicator values ranged from 5.30E-3 to 32E-3 pCi/mn, compared to 4.79E-3 to 29E-3 pCi/m 3 for 2006. The 2007 mean gross beta activity of 15.9E-3 pCi/m 3for all indicator locations compared to the average of the annual preoperational control mean of 62E-3 pCi/mi3 indicates activity detected below the preoperational control. In addition, a comparison of the 2007 indicator mean of 15.9E-3 pCi/mi3 with the 2007 control locations mean of 13.6E-3 pCi/mi3 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 2007.

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 and radium-226, are also observed. Beryllium-7 is cosmogenic in 34 2007 Radiological Environmental Monitoring Report 34 2007 Radiological Environmental Monitoring Report

Atmospheric Pathway Monitoringi origin, being produced by the interaction of cosmic radiation with the earth's atmosphere. The other two gamma-emitting radionuclides originate from soil and rock.

Beryllium-7 was measured above analysis MDCs for all quarterly composite samples in 2007. The 2007 indicator and control means for beryllium-7 activity were 129 and 116 pCi/mi3, respectively. Beryllium-7 activity levels for each 2007 calendar quarter at each monitoring location are presented in Table 1-9 of Appendix I.

Comparisons of 2007 beryllium-7 analysis results with previous years may be found in Table H 14 of Appendix H.

No other gamma-emitting radionuclides were reported for air in 2007.

Beryllium-7 is not attributable to SSES operation.

Air Iodine Iodine-131 has been detected infrequently from 1976, when it was first monitored, through 2007. Since operation 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 the 2007 air monitoring results.

Terrestrial Pathway Monitoring TERRESTRIAL PATHWAY MONITORING INTRODUCTION Soil and milk were monitored in the Terrestrial Pathway in 2007.

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 radionuclide 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 2007. 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 2007 in accordance with its scheduled annual sampling frequency, at the following two REMP air sampling locations: 12S 1 (indicator) and 8G1 (control).

Several soil plugs were taken at selected spots at each monitoring location. The 2007 Radiological Environmental Monitoring Report 37 2007 Radiological Environmental Monitoring Report 37

Terrestrial Pathway Monitorine 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 2007.

Milk Milk was sampled at least monthly at the following locations in 2007: 10D2, 10D3 (10D3 replaced ODI) 13E3 and 10GI.

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, 10D3, and 13E3 are believed to be the most sensitive indicator sites available for the detection of radionuclides released from the SSES. Location 1OGI is the control location. Since there are four monitoring locations, a total of 84 cow milk samples were collected in 2007.

Sample Preservation and Analysis

Figure 13 trends iodine-131 activities separately for milk indicator and control locations from 1977 through 2007.

o Appendix G, Table G pages G-12 through G-14, shows a summary of the 2007 terrestrial monitoring results for milk and soil.

Appendix H, Tables H 15 through 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 1-17 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. Strontium-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.

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 2007:

38 2007 Radiological Environmental Monitoring Report 38 2007 Radiological Environmental Monitoring Report

Terrestrial Pathway Monitorinig Certain naturally occurring radionuclides are also routinely found above analysis MDCs in terrestrial 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 8G1 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, thorium-228 and man-made cesium-137. The 2007 analysis results were similar to those for previous years. No other gamma-emitting radionuclides were reported at levels above analysis MDCs.

The 2007 means for indicator and control location potassium-40 activity were 11,600 pCi/kg and 9,490 pCi/kg, respectively. This is not the result of SSES operation because the potassium-40 is naturally occurring.

The 2007 means for indicator and control location radium-226 activity were 1,150 pCi/kg and 1,900 pCi/kg, respectively. Radium-226 in soil is not the result of SSES operation because it is naturally occurring.

The 2007 means for indicator and control location thorium-228 activity were 785 pCi/kg and 866 pCi/kg, respectively. Thorium-228 in soil is not the result of SSES operation because it is naturally occurring.

The 2007 means for indicator and control location cesium-137 activity were 59 pCi/kg and 131 pCi/kg, respectively. The 2007 indicator values ranged from 46 to 73 pCi/kg, compared to 156 to 190 pCi/kg for 2006.

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. Cesium-137 with its 30 year half life (300 years to decay to non-detectable) it would still be present in samples in 2007. 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 1-10). No detectable iodine-131 activity above MDC was observed at any location for 2007. The 2007 indicator values ranged from -0.48 to 0.58 pCi/l, compared to -1.36 to 0.66 pCi/l for 2006. Iodine-13 1 has been chemically separated in milk samples and counted routinely since 1977. Refer to Figure 13 which trends iodine-131 activity in milk for indicator and control locations from 1977 through 2007, 2007 Radiological Environmental Monitoring Report 39

Terrestrial Path way Monitorinsi 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, no gamma-emitting radionuclides were measured in excess of analysis MDCs in 2007..

The 2007 means for indicator and control location potassium-40 activity were 1,301 pCi/liter and 1,304 pCi/liter, respectively. The potassium-40 activity in milk is not attributable to SSES operation because it is naturally occurring.

Ground Water Monitoring LL!

GROUND, WATE MONITORING 7"

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 conceivably become 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 m6vement 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 pool 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 4 indicator locations (2S2, 4S4, 6S10 and 11S2) and one control location (12F3) during 2007.

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

Untreated means that the water has not undergone any 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 Learning 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.

2007 Radiological Environmental Monitoring Report 42 2007 Radiological Environmental Monitoring Report 42

Ground Water Monitorin2Z 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 1979, 1981, 1985, 1991, 1992, 1993, and 1997. Thorium-228 was found in 1985 and 1986. The man-made radionuclide cesium-137 has been detected only occasionally since 1979. Its presence has always been attributed to residual fallout from previous atmospheric nuclear weapons tests..

Results for the 2007 specific ground water sample analyses may be found in Table 1-7 of Appendix I. A summary of the 2007 ground water monitoring data may be located in Appendix G, pages G-9 and G-10. Comparisons of 2007 monitoring results for tritium with those of past years may be found in Table H 20 of Appendix H.

In 2007, tritium was measured above MDC, in three samples at indicator locations 4S4 at concentrations of 140 and 146 and 11S2 at 143 pCi/l respectively. The activities were slightly above the detection limit. The 2007 indicator values ranged from 11.3 to 146 pCi/l, compared to -9.72 to 178 pCi/l for 2006. The 2007 mean tritium activity levels for indicator and control monitoring locations were 67.6 and 41.9 pCi/l, respectively. Both the 2007 indicator and control mean tritium activity levels are lower than their corresponding range for preoperational years.

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, There have been no indications of any increases in ground water tritium concentrations above normal background levels (based on pre-operational data) since inception of the REMP at PPL Susquehanna.

In 2007, six new ground water monitoring wells were installed at the PPL Susquehanna site. These wells were installed as part of the Action Plan associated with the NEI Initiative on the Protection of Ground Water. Initial results for these six wells are documented in the 2007 Radioactive Effluent Release Report. The six new wells were added to the ODCM in February 2008. Future results from these wells will be reported in the Annual Radiological Environmental Operating Report.

TLD Locations for the SSES Radiological Environmental Monitoring Program - 2007 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 10 miles 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.

APPENDIX D

-2007 S US k ýLAND USE CENSUS RESULTS 2007 Radiological Environmental Monitoring Report D-1 2007 Radiological Environmental Monitoring Report D-1

Appendix D 2007 LAND USE CENSUS RESULTS A Land Use Survey, conducted during the 2007 growing season around the SSES, was performed by Ecology III, Inc. 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 2006 TO 2007 Residence Census:

The residence census was conducted from 26 July through 15 August 2007. 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 2006 census.

Garden Census:

The garden census was conducted on 23 July through 15 August 2007. 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 2.0 miles.

Changes from the 2006 census included: Sector 5 -L. Kozlowski and W. Witts replaced W. Daily (closer garden), Sector 9 -A. Kamir replaced T. Stemrich (closer garden),

Sector 15 -D. Goff replaced R. Reider (closer garden).

Dairy Animal Census:

Seven dairy animal sites were identified in the census conducted from 23 through 31 July 2007. Cows were present at all sites; no dairy goats were found. Changes from 2006 census included two dairies that ceased operations before 2007 census: C. and R.

Ryman (location ODI) and H. Shoemaker (location 16E1). The Drasher Farm (10D3 resumed dairy operations in 2006, but after the 2006 Land Use Census was completed.

The Davis Farm (Sector 10) was included in the dairy census as a control location in the REMP milk sampling program.

Irrigation Two farms irrigated crops using Susquehanna River water downriver from the Susquehanna SES in 2007: Zehner Farm (location 1 1DI - field east of Nescopeck) and the Lupini Field - Route 93 (1 1D2). Zehner irrigated pumpkins, soybeans, and rye, and Lupini irrigated string beans and potatoes. No other farms irrigated this year because 2007 Radiological Environmental Monitoring Report D-2

Appendix D soil moisture was sufficient for the crops. Overall results of the survey are summarized below:

SUMMARY

OF DATAJj~

2007 Radiological Environmental Monitoring Report G-1

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 2007 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.

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.

SUMMARY

2007 Radiological Environmental Monitoring Report J-1 2007 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 environmeintal 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.

2007 Radiological Environmental Monitoring Report J-2 2007 Radiological Environmental Monitoring Report -

J-2 '

Appendix J The criteria for the acceptability of the analyses results for the spikes prepared as part of the PPL REMP LaboratorySpike 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.

COMMENTS (1) Evaluated as a false negative by MAPEP. We did not report the nuclide due to one low result in the three samples analyzed.

The MAPEP known value was 31.1. The three results, including the outlier, averaged 25.6 Bq/kg, which would have been acceptable.

Uranium failure and warning due to not performing microwave digestion on the samples. Next set with be microwave digested.

NCR 07-03 generated by TBE to investigate.

(a) Teledyne Brown Engineering reported result.

(b) The MAPEP known value is equal to 100% of the parameter present in the standard as determined by gravimetric and/or volumetric measurements made during standard preparation.

(c) DOE/MAPEP evaluation: A=acceptable, W=acceptable with warning, N=not acceptable.

NR = not reported, no evaluation was done by MAPEP.
