Summary and Conclusions Radionuclides Contributingto Dosefrom 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 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.

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.

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.

The average 81 was approximately 120 pCi/1 and is tritium concentration in precipitation on- located 5.2 miles WSW of the site was 370 pCi/1 in 2007 and 2008. In Susquehanna site.

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.

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.

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 ft 2) 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 1IDI, 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 obtained in this way might less accurately reflect the conditions for the combined period 0

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.

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.

J-2 2008 Radiological Monitoring Report Environmental Monitoring Radiological Environmental Report J-2

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.
