... C-28 -vi-I. Summary During normal operations of a nuclear power generating station there are permitted releases of small amounts of radioactive material to the environment. To monitor and determine the effects of these releases a Radiological Environmental Monitoring Program (REMP) has been
- established around the Susquehanna Steam Electric Station (SSES). The results of the REMP are published annually, providing a summary and interpretation of the data collected.
Ecology Ill was responsible for the collection of environmental samples duril)g 2013. Teledyne Brown Engineering (TBE) was responsible for the analysis of environmental samples during 2013. The results are discussed in this report. Landauer provided the dosimetry services for SSES during 2013. This Annual Radiological Environmental Operating Report (AREOR) conducted for SSES covers the period January 1, 2013 through December 31, 2013. During that time period, 1373 analyses were performed on 1125 samples. Of the two man-made radionuclides (tritium [H-3] and cesium-137
[Cs-137])
detected in the environment by the Susquehanna Steam Electric Station (SSES) Radiological Environmental Monitoring Program (REMP), tritium is the only radionuclide attributable toSSES operation.
The whole body and organ dose to members of the public attributable to tritium identified in REMP cooling tower blowdown samples was 7.27E-04 mRem. Tritium was included in the dose calculation because it was identified in the REMP samples of water being discharged to the Susquehanna River. The 2013 average concentration of tritium in the cooling tower blowdown water and the 2013 average cooling tower blowdown flow 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. Dose from ground plane deposition (shoreline exposure) is not applicab l e because tritium does not emit gamma radiation and the beta radiation emitted by tritium is not sufficiently penetrating to reach an individual on the shore. Based on the above outlined methodology, the total tritium activity r eleased from the SSES to the Susquehanna River in 2013 was 79.3 curies. The 2013 average dilution factor for the Susquehanna River was 697 , based on the annual average river flow of 8.20E+06 gpm and the annual average cQoling tower_blowdown flow of 1 .18E+04 gpm. The REMP Sample Equipment Operability and year to year trend comparison is located in Appendix E, Table E-1 The REMP was conducted in accordance with the SSES Technical Requirements Manual (TRM) and the respective station Offsite Dose Calculation Manual (ODCM) which are based on the design objectives i n 1 OCFR Part 50 Appendix I , Sections IV.B.2, IV.B.3 and I V.C. The Lower Limit of Detection (LLD) values required by the TRM and SSES ODCM were achieved for the 2013 reporting period. The REMP objectives were also met during this period. The concentration of radioactive ma t erial in the environment that could be attributable to SSES operations was only a sma ll fraction of the concentration of naturally occurring and man-made radioactivity.
Since these results were comparable to the results obtained during the preoperational phase of the program and combined with historical results collected since commercial operation , it can be concluded that the levels and fluctuations were as expected and that the operation of the SSES had no significant radiological impact on the environment.
Additionally, the REMP sample results for 2013 verify the adequacy of the SSES radioactive effluent control systems.
Samples of air particulates, air iodine, milk, groundwater, drinking water, vegetation, soil, surface water, fish and sediment were collected and analyzed. External radiation dose measurements were also made in the vicinity of SSES using passive dosimeters.
Air particulate samples were analyzed for concentrations of gross beta weekly and gamma emitting nuclides quarterly.
Gross beta and cosmogenically produced beryllium-? (Be-7) were detected at levels consistent with those detected in previous years. No fission or activation products were detected.
High sensitivity iodine-1_31 (1-131) analyses were performed on weekly air samples. All res.ults were less than the minimum detectable concentration.
- Environmental gamma radiation measurements were performed quarterly using Optically Stimulated Luminescent dosimeters (OSLO). The levels of radiation detected were consistent with those observed in previous years. Cow milk samples were analyzed for concentrations of 1-1 31 and gamma emitting nuclides.
All 1-131 results were below the minimum detectable concentration.
Naturally occurring potassium-40 (K-40) was detected at levels consistent with those detected in previous years. No fission or activation products were detected.
A one-time collection of four pasture grass samples was made from two locations in 2013. Naturally occurring Be-7 and K-40 were detected in the four samples at concentrations ranging from 650 to 1 ,090 pCilkg wet and 3230 to 8060 pCi/kg wet, respectively.
Preoperational data is not available for comparison.
Groundwater samples were analyzed for concentrations of tritium and gamma emitting nuclides.
Tritium activities detected were consistent with those detected in previous years. No fission or activation products were detected.
Drinking water samples were analyzed for concentrations of tritium, gross beta and gamma emitting nuclides.
Tritium and gross beta activities detected were consistent with those detected in previous years. No fission or activation products were detected.
Food product (fruits, vegetables and broadleaf vegetation) samples were analyzed for concentrations of gamma emitting nuclides. Naturally occurring potassium-40 was detected at levels consistent with those detected in previous years. No fission or activatiqn products were detected.
Soil samples were analyzed for concentrations of gamma emitting nuclides.
In addition to the naturally occurring isotopes (i.e. K-40, thorium-228
[Th-228], radium ... 226 [Ra-226] and actinium-228
[Ac-228]), Cs-137 was detected in one of the soil samples. The sample data is consistent with historical and preoperational data which indicates that the presence of Cs-137 in the soil is due to residual fallout from atmosphe r ic nuclear weapons testing in the 1970s and early 1980s and the Chernobyl event. Surface water samples were analyzed for concentrations of tritium and gamma emitting nuclides.
Tritium activities detected were consistent with those detected in previous years. No fission or activation products were detected.
Fish and shoreline sediment samples were analyzed for concentrations of gamma emitting No fission or activation products were detected in fish or sediment samples.
II. The Radiological Environmental Monitoring Program The SSES is located on approximately a 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. The station consists of two barling water reactor generating units. Each unit has completed an Extended Power Uprate process which has increased licensed thermal power from 3489 MWt (megawatt thermal) to 3952 MWt. Unit-1 completed the power up rate in 2010 and Unit 2 completed the power uprate in 2011. 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. Radioanalytical data from samples collected under the REMP were compared with results from the preoperational phase and historical results during operations.
Differences between these periods were examined statistically to determine the effects of station operations.
This report presents the results from January 1 through December 31, 2013, for the SSES Radiological Enviro.nmental Monitoring Program (REMP). A. Objectives of the Operational REMP The objectives of the Operational REMP are to: 1. Document compliance with SSES REMP Technical Requirements and radiological environmental surveillances.
- 2. Verify proper implementation of SSES radiological effluent controls.
- 3. Identify, measure and evaluate trends of radionuclide concentrations in environmental pathways near SSES. 4. Assess impact of SSES Effluents on the Environment and the public. 5. To verify that SSES operations have no detrimental effects on the health and safety of the public or on the environment.
B. Implementation of the Objectives
- 1. In order to meet the objectives, an operational REMP was developed.
Samples of various media were selected for monitoring due to the radiological dose impact to humans and other organisms.
The selection of samples was based on: (a) Established critical pathways for the transfer of radionuclides through the environment to man, and (b) Experience gained during the preoperational phase. Sampling locations were determined based on site meteorology, Susquehanna River hydrology, local demography, and land uses. 2. Sampling locations were divided into two classes, indicator and control. Indicator locations are sited where it is expected th at radiation and radioactive material that might originate from the station would be detectable.
Control locations are selected in areas where they would be unaffected by station operations (i.e. Susquehanna River upstream from the station, >1 0 miles from the station in least prevalent wind directions).
Fluctuations in the levels of radionuclides and direct radiation at indicator locations are evaluated with respect to analogous fluctuations at control locations.
Indicator and control location data are also evaluated relative to preoperational data. 3. Appendix A, Summary of Data for SSES, describes and summarizes the analytical results in accordance with the SSES Technical Specifications.
- 4. Appendix B, Location, Designation, Distance, Direction and Sample Collections and Analytical Methods, describes the coding system which type and location.
Table B-1 lists the location codes, locations, latitude, longitude, and the types of samples collected at each location.
Table B-2 contains sample medium, analysis and sampling details. 5. The sampling locations are indicated on the following maps: Map B-1, Direct Radiation Monitoring Locations Within One Mile Map Direct Radiation Monitoring Locations From One to Five Miles Map B-3, Direct Radiation Monitoring Locations Greater Than Five Miles Map B-4, Environmental Sampling Locations Within One Mile Map B-5, Environmental Sampling Locations From One to Five Miles Map B-6, Environmental Sampling Locations Greater Than Five Miles Ill. Program Description A. Data Interpretation Results of analyses are grouped according to sample type and presented in Appendix C, Data Tables. All results above the Lower Limit of Detection (LLD) are at a confidence level of+/- 2 sigma. This represents the range of values into which 95% of repeated analyses of the same sample should fall. As defined in U.S. Nuclear Regulatory Commission Regulatory Guide 4.8, LLD is the smallest concentration of radioactive material in a sample that will yield a net count (above background) that will be detected with 95% probability, with only 5% probability of falsely concluding that a blank observation represents a "real signal". LLD is normally calculated as 4.66 times the standard deviation of the background counting rate, or of the blank sample count, as appropriate, divided by counting efficiency, sample size, 2.22 (dpm per picocurie), the radiochemical yield when applicable, the radioactive decay constant and the elapsed time between sample collection and time of counting.
The LLD is an "a priori" number which represents the capability of the measurement system. The Minimum Detectable Concentrc;ttion (MDC) is defined as the smallest concentration of radioactive material that can be detected at a given confidence level. The. MDC differs from the LLD in that the MDC takes into consideration the interference caused by the presence of other nuclides while the LLD does not. The MDC is an "a posteriori" number which is an indicator of the performance of the measurement system. The MDC is set to be below the LLD. The grouped data were averaged and standard deviations calculated.
Thus, the +/- 2 sigma deviations of the averaged data represent sample and not analytical variability.
For reporting and calculation of averages, any result occurring at or below the LLD is considered to be at that level. B. Program Exceptions Date Sample Location Exception Corrective Action Type 01/16/13 to AP/C 6G1 Timer box malfunction-01/23/13:
