Summary and Conclusions RadionuclidesContributingto 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 0.0016 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 Radioactivity levels in environmental K 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.

AppendiX A ELEVATED 1-131 Levels in 2S7 Sample Location A concentration of 3.03 pCi/l was calculated as the quarterly average 1-131 activity concentration in the CTBD line for the third quarter 2005 based on analysis results using the appropriate weighting factors. Elevated 1-131 levels observed at 2S7 sample location exceeded the reporting level of 2 pCi/l per TRM Table 3.11.4.1-2; however, the observed iodine-131 was not the result of Susquehanna plant effluents for the following reasons:

The "Monthly Gaseous and Liquid Radiological Effluent Report" listed no iodine-131 as having been released in liquid effluent for July, August, and September 2005 based on the results of sampling and analyses of the liquid contents of tanks prior to discharge.

SSES Units 1 and 2 have not observed any indication of fuel failure during this period. Unit 1 and 2 Reactor Coolant System iodine-131 activities have been very low (1-to 2E-6 gCi/ml). Unit 1 and 2 Offgas Xe-138/Xe-133 ratio trends have indicated no fuel defects.

Of the 78 REMP air samples analyzed for iodine-131 during the third quarter

- 2005 in the vicinity of the Susquehanna SES, all were below the lower limit of detection. It is reasonable to conclude that atmospheric releases from Susquehanna SES can not explain the iodine-131 levels seen in the Susquehanna River:

Apparent Cause Varying levels of iodine-131 in medical waste discharged upriver from municipal waste facilities and varying river levels cause fluctuations in iodine- 131 activity concentrations in the river with time. The coincidence of larger iodine-131 releases upstream with lower river levels can result in significantly higher iodine-131 concentrations. During June through October (warmer months), river flow generally tends to be below the average for the year. This increases the chance of observing higher activity concentrations at this time of year. The CTBD, location 2S7, I-131 activity of 3.03 pCi/I for the third quarter of 2005 can be explained by the concentrating effect of the cooling towers on the I-131 activity (1.53 pCi/l) found in river water upstream of the SSES (control location 6S6) which is used for makeup to the cooling tower. Based on the average makeup and blowdown flow rates for the third quarter, and using methodology in EC-ENVR-1037, the 1-131 activity in the upstream river water should be concentrated by a factor of 3.36.

Thus, the calculated concentration of I-131 in the CTBD due to concentration of upstream activity would be 5.1 pCi/l. The fact that the actual concentration of I-131 reported (3.03 pCi/l) was less than the calculated value supports the conclusion that the I-131 found in CTBD samples in third quarter of 2005 is not due to the operation of SSES.

2005 Radiological Envirommental Monitoring Report D-1

Appendix D 2005 LAND USE CENSUS RESULTS A Land Use Survey, conducted during the 2005 growing season around the SSES, was performed by Ecology mII, 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 2004 TO 2005 Residence Census:

The residence census was conducted from 1 August through 13 September 2005.

Distances of the nearest residences from the Susquehanna SES in the 16 different sectors ranged from 0.5 (J.Futoma, sector 7) to 2.1 miles (R. Barberi, sector 4), with an average of approximately 1.0 miles.

Changes from the 2004 census included: G. John (Sector 16) @ 0.6 mile replaced W.

Metzler (moved).

Garden Census:

The garden census was conducted on 1 August through 13 September 2005. 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 1.9 miles.

Changes from the 2004 census included: A. Kadir (Sector 9) @ 1.2 mile replaced M.

Cope (no garden this year), and R. Broody (Sector 11) @ 1.9 mile replaced H. Schultz (no garden this year).

Dairy Animal Census:

Ten dairy animal sites were identified in the census conducted on 25 and 26 July 2005 (9 were within 5 mile radius and one was the control at 14 miles). The numbers of sites were the same as in 2004. Cows were present at all sites; no dairy goats were found. It is noted that after completion of the census, C. and K. Drasher(101D3) discontinued milking and sold their dairy animals. This reduces the number of active dairies in the 5-mile radius to eight.

Irrigation Unusual amounts of rainfall affected the sizes of gardens and amount of irrigation in 2005. Irrigated fruits and vegetables were monitored at the Lupini Farm (12F7 -

Mifflinville field) irrigated potatoes in July 2005, and the Zehner Farm (1 IDI - field east of Nescopeck) irrigated pumpkins in July and August 2005, using Susquehanna River water downriver from the Susquehanna SES. The Chapin Farm (SS 11 - PPL Report D-2 2005 Environmental Monitoring Radiological Environniental 2005 Radiological Monitoring Report - D-2

Appendix D Susquehanna Project East Side Parcel 25) irrigated potato fields using Susquehanna River water above the intake. As a result of this survey, 5S 1I location was added to the SSES REMP. Overall results of the survey are summarized below:

Appendi 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 whidh 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 2005 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.

Radiological Environmental 2005 Radiological Monitoring Report I-1 2005 Environmental Monitoring Report I-1

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

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

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

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

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

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

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

(4) TLDs were not in the field at this monitoring location during this quarter. Refer to Appendix A of this report for an explanation of program changes to the REMP (not applicable for 2005 data).

(5) No measurement could be made because the TLDs were lost, stolen or damaged. Refer to Appendix A for explanation of analysis exceptions.

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

(7) Data were invalidated for this period because of an unacceptably high coefficient of variation among element readings (not applicable for 2005 data).

(8) Extra TLD location, not required by TRM/ODCM (i.e. do not provide additional benefit) and were deleted from the monitoring program in 2nd quarter of 2004.

Appendix J The data in the tables that follow show how well Framatome ANP Environmental Laboratory and Teledyne Brown Engineering Environmental Services (TBE) performed in the analysis of radioactively spiked media. Tables J-1 through J-5 provide the performance results for Framatome ANP. Tables J-6 through J-10 provide the performance results for TBE. In addition to the Analytics' spikes analyzed as part of PPL's REMP Laboratory Spike Program (Tables J-3 and J-8), Framatome ANP and TBE analyzed spikes procured independently from Analytics as part of their respective Quality Control Spike Programs (Tables J-2 and J-7), as well as spikes prepared as part of the following programs:

1. The Proficiency Testing Program of Environmental Resource Associates (Tables J-1 and J-6)

2. The Quality Assessment Program of DOE's Environmental Measurements Laboratory (EML)

(Tables J-4 and J-9) was discontinued in March 2004.

3. The Mixed Analyte Performance Evaluation Program (MAPEP) of the DOE (Tables J-5 and J-10)

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 as 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.

2005 Radiological Envirommental 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 Laboratory Spike Program (Tables J-3 & J-8) have 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 - Tables J-5 and J-1O are 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-10. Discussions relevant to these comment numbers follow the presentations of the data, as applicable.

COMMENTS 1 NCR 05-18 assigned to investigate low bias in Sr-90 in soil - pending fusion procedure development 2 DOE/MAPEP evaluation: A=acceptable, W=acceptable with warning, N=not acceptable. Performance is considered acceptable when a mean result for the specified analyte is

20% of the reference value.

Performance is acceptable with warning when a mean result falls in the range from

20% to +/- 30%/6 of the reference value (i.e., 20% < bias < 30%). If the bias is greater that 30%, the results are deemed not acceptable.

3 High Bias identified. Evaluation of results requested by PPL via email on April 10, 2006.
