SUMMARY

During normal operations of a nuclear power generating station there are 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 for the environment around Artificial Island where the Salem Generating Stations (SGS) and Hope Creek Generating Station (HCGS) are located. The results of the REMP are published annually, providing a summary and interpretation of the data collected.

PSEG's Maplewood Testing Services (MTS) has been responsible for the collection and analysis of environmental samples during the period of January 1, 2005, through December 31, 2005, and the results are discussed in this report. The REMP for SGS/HCGS was conducted in accordance with the SGS and HCGS Technical Specifications/Offsite Dose Calculation Manual. The Lower Limit of Detection (LLD) values required by the Technical Specifications/ODCM were achieved for this reporting period. The objectives of the program'were also met during-this period. The data collected assists in demonstrating that SGS'and HCGS were operated in compliance with Technical Specifications/ODCM.

Most of the radioactive materials'noted in this report are normally present in the environment, either naturally, such as potassium-40, or as a result of non-nuclear generating station activity, such as nuclear bomb testing.'

Measurements made in the vicinity of SGS/HCGS were compared to background or control measurements and the preoperational REMP study performed before Salem Unit 1 became operational.

'-Samples of air particulates, air iodine, milk, surface, ground and drinking water, vegetables, game, fodder crops, fish, crabs, and sediment were collected and analyzed.

External radiation dose measurements were also made in the vicinity of SGS/HCGS using thermoluminescent dosimeters.

From the results obtained, it can be concluded that the levels and fluctuations of radioactivity in environmental samples were as expected for an estuarine environment.

No unusual radiological characteristics were observed in the environs of SGS/HCGS during this reporting period. Since these results were comparable to the results obtained during the preoperational phase of the program, and with historical results collected since commercial operation, we can conclude that the operation of SGS and HCGS had no significant impact on the radiological characteristics of the environs of these stations.To demonstrate compliance with Technical Specifications/ODCM (Sections 3/4.12.1 & 6.8.4.h -1,2,3), samples were analyzed for one or more of the following:

gamma emitting isotopes, tritium (H-3), iodine-131 (I-131), gross beta and gross alpha.1 The results of these analyses were used to assess the environmental impact of SGS and HCGS operations, thereby demonstrating compliance with Technical Specifications/ODCM (Section 3/4.11) and applicable Federal and State regulations, and to verify the adequacy of radioactive effluent control systems.The results provided in this report are summarized below:* There were a total of 1452 analyses on 1124 environmental samples during 2005, including direct radiation dose measurements made using 195 thermoluminescent dosimeters (TLDs).* In addition to the detection of naturally

-occurring isotopes (i.e. Be-7, K-40, Radium and Th-232) trace levels of H-3 and Cs-137 were also detected.

The concentrations of these nuclides were well 'below the Technical Specification reporting limit.,* Dose measurements made with quarterly TLDs at 31 offsite locations around the SGS/HCGS site averaged 50 millirems for the year 2005. The average of the dose measurements at the control locations (background) was 53 millirems for the year.This was comparable to the preoperational phase of the program which had an average of 55 millirems per year for 1973 to 1976. -During 2005, PSEG Nuclear'continued remedial actions for tritium identified in shallow groundwater at Salem Station. These remedial actions have been conducted in accordance with a'Remedial Action Work Plan that was approved by the New Jersey Department of Environmental Protection

-Bureau of Nuclear Engineering (NJDEP-BNE) in.,November, 2004. A groundwater recovery/extraction system[GRS] has been installed.'consisting of eight wells, associated pumps and, continuous sampling equipment.

The GRS is in operation, providing hydraulic, control of plume and effectively removing tritium contaminated groundwater.

The tritium contaminated groundwater is disposed of in accordance with Salem Station's liquid radioactive waste disposal program. There is no evidence or indication that tritium contaminated water'above Ground Water Quality Criteria (GWQC)'levels

[GWQC is <20,000 pCi/L] has migrated to the station boundary or the Delaware River.2 THE RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM Lower Alloways Creek Township, Salem County, New Jersey is the site of Salem (SGS)and Hope Creek (HCGS) Generating Stations.

SGS consists of two operating pressurized water nuclear power reactors.Salem Unit One has a net rating of 1177 megawatt electric(MWe) and Salem Unit Two has a net rating of 1134 MWe. The licensed core power for both units is 3459 megawatt thermal (MWt). HCGS is a boiling water nuclear power reactor, which has a net rating of 1094 MWe (3339 MWt).SGS/HCGS are located on a man-made peninsula on the east bank of the Delaware River. It was created by the deposition of hydraulic fill from dredging operations.

The environment surrounding SGS/HCGS is characterized mainly by the Delaware River and Bay, extensive tidal marshlands, and low-lying meadowlands.

These land types make up approximately 85% of the land area within five miles of the site.Most of the remaining land is used for agriculture

[1,2]. More specific information on the demography, hydrology, meteorology, and land use of the area may be found in the Environmental Reports[1,2], Environmental Statements

[3,4], and the Updated Final Safety Analysis Reports for SGS and HCGS [5,6]..Since 1968, a radiological environmental monitoring program- (REMP)has been conducted at the SGS1HCGS Site. Starting in December, 1972, more extensive radiological monitoring programs were initiated.

The operational REMP was initiated in December, 1976, when Salem Unit 1 achieved criticality.

PSEG's Maplewood Testing Services (MTS) has been involved in the REMP since its inception.

MTS is responsible for the collection of all radiological environmental samples and, from 1973 through June, 1983, conducted a quality assurance program in which duplicates of a portion of those samples analyzed by the primary laboratory were also analyzed by MTS.From January, 1973, through June, 1983, Radiation Management Corporation (RMC) had primary responsibility for the analysis of all samples under the SGS/HCGS REMP and annual reporting of results. RMC reports for the preoperational and operational phase of the program are referenced in this report [7-9]. On July 1, 1983, MTS assumed primary responsibility for the analysis of all samples (except TLDs)and the reporting of results. Teledyne Brown Engineering Environmental Services (TBE), assumed responsibility for third-party QA analyses and TLDs. An additional vendor, Controls for Environmental Pollution Inc. (CEP), was retained to provide third-party QA analyses and certain non-routine analyses from May, 1988, until June 1, 1992. Currently, Framatome ANP, Inc. Environmental Laboratory (Framatome) is the third party QA vendor and the laboratory which performs the TLD analyses.

MTS reports for the operational phase from 1983 to 2004 are referenced in this report[10].3 An overview of the 2005 Program is provided in Table 1.Radioanalytical data from samples collected under this program were compared with results from the preoperational phase. 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, 2005, for the SGS/HCGS REMP.OBJECTIVES The objectives of the Operational REMP are:* To fulfill the requirements of the Radiological Surveillance sections-of the Technical Specifications/ODCM for SGS/HCGS.* To determine whether any significant increase occurred in the concentration of radionuclides in critical pathways.* To determine if SGS or HCGS has caused an increase in the radioactive inventory of long-lived radionuclides.

• To detect any change in ambient gamma-radiation levels.* To verify that SGS and HCGS operations have no detrimental effects on the health and safety of the public or on the environment.

This report, as required by Section 6.9.1.7- of the Salem Technical Specifications/ODCM and Section 6.9.1.6 of the Hope Creek Technical Specifications/'ODCM, summarizes the findings :of the 2005 REMP.Results of the four-year preoperational program have been summarized for comparison with subsequent operational reports [8].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 human and other organisms.

The selection of samples was based on: (1), established critical pathways for the transfer of radionuclides through the environment to man, and, (2), experience-gained during the preoperational phase.Sampling locations were determined based on site meteorology, Delaware,-estuarinb hydrology, local demography, and land uses.Sampling locations were divided-into two classes-, indicator and control. Indicator stations are-those, which are expected to manifest station effects. Control samples -are collected-at locations which are believed to be unaffected by station-operations, usually at 15 to 30 kilometers distance.

Fluctuations in the levels of radionuclides and direct radiation at indicator stations are evaluated with respect to analogous fluctuations at control stations.

Indicator and control station data are also evaluated relative to preoperational data. Appendix A describes and summarizes, in accordance with Section 6.9.1.7- of the Salem TS and Section 6.9.1.6 of the Hope Creek TS, the operational program as performed in 2005.'4 Appendix B describes the coding system which identifies sample type and location.

Table B-1 lists the sampling stations and the types of samples collected at each station. These sampling stations are indicated on Maps B-1 and B-2.DATA INTERPRETATION Results of analyses are grouped according to sample type and presented in Appendix C. 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 Regulatory Guide 4.8, LLD is the smallest concentration of radioactive material in a sample that will yield a net count (above system background) that will be detected with: 95% probability with only 5% probability of falsely concluding that-a blank observat-ion-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 bly -count-ing--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 Minimum Detectable Concentration (MDC) -is defined as .theesmaJlest -concentration of radioactive material ~that_ can beI .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. riot.., -The grouped data were averaged and ..standard deviations calculated in accordance with Apgendixc-B -of.

For reporting and calculation of averages, any result occurring at or below' the LLD is considered to be.at that level.When a group of data was composed of:.50t or more LLD-values, averages were not-.calculated-

Approximately 20% of the total analytical effort is spent on quality control, including process quality 5 control, instrument quality control, interlaboratory cross-check analyses, and data review.The quality of the results obtained by MTS is ensured by the implementation of the Quality Assurance Program as described in the Maplewood Testing Services Quality Assurance Plan [11] and the Environmental and Chemical Division Procedures Manual. The internal quality control activity of MTS includes the quality control of instrumentation, equipment and reagents; the use of reference standards in calibration, documentation of established procedures and computer programs, and analysis of duplicate samples. The external quality control activity is implemented through participation in both the Analytics and the Environmental Resource Associates Interlaboratory Comparison Programs.

The results of these Interlaboratory Comparison Programs are listed in Tables D-1 through D-4 in Appendix D.PROGRAM:CHANGES Since there are no-milk farms-or gardens--within 5 km of the Site, MTS personnel planted, maintained-and harvested a broad leaf vegetation sample. Ornamental cabbage was planted in the fall in floral greenhouses at three locations onsite (lS1, 15S1 and 16S1)and one location 3.9 miles SSW across the river (lODI). The samples were then collected in the last week of December.RESULTS AND DISCUSSION The analytical results of the 2005 REMP samples are divided into categories based on exposure pathways:

atmospheric, direct, terrestrial, and aquatic. The analytical results for the 2005 REMP are summarized in Appendix A. The data for individual samples are presented in Appendix C. The data collected demonstrates that the SGS and HCGS REMP was conducted in compliance with the Technical Specifications/ODCM.

The REMP'for the SGS/HCGS Site has historically included samples and analyses not specifically required by these Stations' Technical Specificat-ions/ODCM.

MTS continues to collect and analyze some of these samples in order to maintain personnel proficiency in performing these non-routine analyses.

These analyses are referenced throughout the report as Management Audit samples. The summary tables:'in this report include these additional samples and analyses.ATMOSPHERIC Air particulates were collected on Schleicher-Schuell No. 25 glass fiber filters with low-volume air samplers.6 Iodine was collected from the air by adsorption on triethylene-diamine (TEDA) impregnated charcoal cartridges connected in series after the air particulate filters. Air sample volumes were measured with calibrated dry-gas meters and were corrected to standard temperature and pressure.Air Particulates (Tables C-1, C-2)Air particulate samples were collected weekly, at 6 locations.

Each of the 310 samples.(see Program Deviations).collected for the year were analyzed for gross beta. Quarterly composites of the weekly samples from each station were.analyzed for specific gamma emitters.Total data recovery for the 6 sampling stations in 2005 was greater than 99 percent.* Gross beta activity was detected in all of the indicator station samples collected at concentrations ranging from 8 x 10-3 to 51 x 10-3 pCi/M 3 and in all of the control station samples from 9 x 10-3 to 46 x 10-3 pCi/M 3.The averages for the indicator and control station;.samples were,23 and 24 x 10- pCi/m 3 , respectively.

The maximum-.preQperational level detected-was.

920 -x lO-.3pCi/m3, with an average of 74 x 10-3 pCi/M 3..iResults -from...1985,to current.year are plotted on Figure- 1.as quarterly averages.

Included along with this plot, for purposes of comparison, is an inset depicting a continuation of this plot from the current year all the way back to 1973.* Gamma spectroscopy, performed on each of the 24 quarterly composite samples analyzed4.indicated the presence of the naturally-occurring radionuc;lides.Be-7 and K-40.. All other gamma emitters:.

searched-for were below the LLD.o Beryllium-7, attributed to cosmic ray activity in the atmosphereswas detected in all 20 indicator station composites that were analyzed, at concentrations ranging from 63 x 10-3 to 77 x 10- pCi/mi, with an average of 69 x 10-3 pCi/n 3.It was detected in -the 4 control station composites ranging-from.58-x -0 3-to 71 x 10- pCi/n 3 , with an average of 63 x. In..pCi/r 3.The maximum preoperational level detected was -330 x 10-l : pCi/m 3 , with an average of 109 x 10-3 pCi/Mr 3..o Potassium-40 activity was detected in 17 of, the indicator station samples, with concentrations ranging from 8 x 10-3 to 30 x 10 pCi/M 3 , with an average of 12 x 10-3 pCi/M 3.K-40 was also detected in 3 control station samples, at concentrations from 9 x 10-3 to 17 x 10-3 pCi/M 3 with an average of 12 x 10-3 pCi/M 3.No preoperational data is available for comparison.

7 Air Iodine (Table C-3)Iodine in filtered air samples was collected weekly, at 6 locations.

Each of the 310 samples collected (see Program Deviations) for the year was analyzed for I-131.Iodine-131 was not detected in any of the weekly samples analyzed.LLD sensitivities for all the stations, both indicator and control, ranged from <1.2 x 10-3 to <15 x 10-3 pCi/M 3.The maximum preoperational level detected was 42 x 10-3 pCi/M 3.DIRECT RADIATION Ambient radiation levels in the environs were measured with energy-compensated CaSO 4 (Tl) thermoluminescent dosimeters (TLDs) supplied and read by Framatome.

Packets containing TLDs for quarterly exposure were placed in the owner-controlled area and around the Site at various distances and in each land based meteorological sector. Special emphasis was placed on special interest areas such as population centers, nearby residences, and schools.Direct Radiation (Table C-4)A total of 49 locations were monitored for direct radiation during 2005, including 12 on-site locations, 31 off-site locations within the 10 mile zone, and 6 control locations beyond 10 miles. Effort was made to locate TLDs at schools and population centers in the area.Five readings for each TLD (ie; 5 elements) at each location were taken in order to obtain a more statistically valid result. For these measurements, the rad is considered equivalent to the rem, in accordance with 10CFR20.1004.

The average dose rate for the 31 quarterly off-site indicator TLDs was 4.2' millirads per standard month, while the on-site average was 4.4 millirads per standard month,. The average control rate was 4.4 millirads per standard month. The preoperational average for the quarterly TLD'readings was 4.4 milli-rads per standard month.In Figure 2, the quarterly average-radiation levels of the off-site indicator stations versus the control stations, are plotted for the period 1985 through 2005, with an inset graph depicting the current year back to 1973.TERRESTRIAL Milk samples were taken semi-monthly when cows were on pasture and monthly when cows were not grazing on open pasture. Animals are considered on pasture from April to November of each year. Samples were collected in polyethylene containers and transported in ice chests with no preservatives added to the milk.8 A well water sample was collected monthly. Separate raw and treated potable water samples were composited daily at the City of Salem water treatment plant. All samples were collected in new polyethylene containers.

Locally grown vegetable and fodder crops were collected at the time of harvest with the exception of ornamental cabbage. MTS personnel planted, maintained and harvested this broad leaf crop in the fall from three locations on site and one across the river. All samples were weighed and packed in plastic bags.Game (muskrat) has been collected annually (time of year dependent on weather conditions, which affect pelt thickness) from local farms after being trapped, stripped of their pelts and gutted. The carcasses were packed in plastic bags and kept chilled in ice chests during transport.

Milk (Table C-5)Milk samples were collected at 4 local dairy farms (2 farms in NJ and 2 in Delaware).

Each sample was analyzed for I-131 and gamma emitters.* Iodine-131 was not detected in any of the 80 samples analyzed.LLD sensitivities for -both the indicator and-the control station samples ranged from <0.1.to 0.7 pCi/L. The maximum preoperational level detected-was 65 pCi/L which occurred following a period of atmospheric-nuclear weapons tests.Results from 1985 to 2005 are plotted on Figure 3, with an inset graph depicting the current year back to 1973.* Gamma spectroscopy performed.

on each of-the 80 samples indicated the-presehce of the- naturally-occurring radionuclide.

K-40. All other gamma emitters searched for were below the LLD.0 Potassium-40 was detected in all:'80. samples. Concentrations for the 60-indicator station samples ranged from 1210 to 1440 pCi/L, with an average-of 1340 pCi/L. The 20-control station sample concentrat~ions ranged from 123.0 to 1420 pCi/L, with an average of 1300 pCi/L. The maximum preoperational level detfected-was 2000 pCi/L, with an average of 1437 pCi/L.Well Water (Ground Water) (Tables C-6, C-7)Although wells in the vicinity of SGS/HCGS are not directly affected by plant operations, water samples were collected monthly from one farm's well during January through December of the year. Each sample was analyzed for gross alpha, gross beta, tritium, and gamma emitters.U Gross alpha activity was detected in 1 of the well water samples at a concentration of 3.2 pCi/L.9 The maximum preoperational level detected was 9.6 pCi/L. There was no preoperational average determined for this analysis.* Gross beta activity was detected in all 12 well water samples.Concentrations for the samples ranged from 9.,2 to 11 pCi/L, with an average of 10 pCi/L. The 2005 gross beta results are comparable with the preoperational results which ranged from<2.1 to 38 pCi/L, with an average value of 9 pCi/L.* Tritium activity was not detected in any of the well water samples. The LLD sensitivities ranged from <145 to <155 pCi/L.The maximum preoperational level detected was 380 pCi/L. There was no preoperational average determined for this analysis.* Gamma spectroscopy performed on each of the 12 well water samples indicated the presence of the naturally-occurring radionuclides K-40 and Radium. All other gamma emitters searched for were below the LLD.o Radium was detected in all 12 of the well water samples at concentrations ranging from 36'to 155 pCi/L-with an average of 102 pCi/L. The maximum preoperational level detected was 2.0 pCi/L. There was no preoperational average determined-for this analysis.These values are similar to those found in the past 16 years. However, as with the 1989 through 2005 results, they are higher than those found in the preoperational program.These results are due to a procedural change for sample preparation.

The change results in less removal of radon (and its daughter products)ifrom the sample. It is.reasonable to conclude that values currently observed are typical for this region.o Potassium-40 was detected' in 3 of the samples at concen-trations ranging from 63 to 101 pCi/L and an average of 84 pCi/L. The maximum preoperational level detected was 30 pCi/L. There was no preoperational average determined for this analysis.-

Potable Water (Drinking Water) (Tables C-8, C-9)Both raw and treated potable water samples were collected and composited by Salem water treatment plant personnel-.

Each sample consisted of daily aliquots composited into a monthly sample. The raw water source for this plant is Laurel Lake and its adjacent wells. These are management audit samples as no liquid effluents discharged from SGS/HCGS will directly affect this pathway. Each of the 24 individual samples was analyzed for gross alpha, gross beta, tritium, iodine-131 and gamma emitters.10

• Gross alpha activity was detected in 5 raw water samples at concentrations of 0.5 to 1.9 pCi/L and in 1 treated water samples at 0.5 pCi/L. The averages for both raw and treated water samples was 0.9 pCi/L. The maximum preoperational level detected was 2.7 pCi/L. There was no preoperational average determined for this-analysis.

• Gross beta activity was detected in all 12 raw water samples at concentrations ranging from 2.6 to 3.9 pCi/L. Concentrations for the treated water ranged from 2.5 to 3.9 pCi/L. The average concentration for both raw and treated was 3.1 pCi/L.The maximum preoperational level detected was 9.0 pCi/L, with an average of 4.2 pCi/L.* Tritium activity was not detected in any of the raw or treated potable water samples. LLD sensitivities for the raw and treated samples ranged from <139 to <156 pCi/L. The maximum preoperational level detected was 350 pCi/L, with an average of 179 pCi/L.* Iodine-131.

measurements were performed to a sensitivity of 1.0 pCi/L, even though the drinking water supplies are not affected by discharges from the Site since the receiving water body (Delaware River) is brackish and therefore the water is not used for human consumption.

Iodine-131 measurements for all 24 samples were below the LLD sensitivities.

These sensitivities ranged from <O.1 to <0.4 pCi/L. There was no preoperational data available for comparison.

• Gamma spectroscopy.performed on each of the 24 monthly water samples indicated the presence of the naturally-occurring radionuclides K-40 and Radium. All other gamma emitters searched for were below the LLD.O The radionuclide K-40 was detected in 9 of the treated potable waters-at concentrations ranging from 36 to 92 pCi/L. It was detected in 7 of the raw potable water samples-at concentrations from 30 to 84 pCi/L. The average for both raw and treated-results was 41 pCi/L. LLD sensitivities for the remaining 8 potable water samples were <14 to <17 pCi/L. There was no preoperational data available for comparison.

O Radium was detected in 3 of the treated potable waters at concentrations ranging from-5.7 to 15 pCi/L. It was not detected in any of the raw potable water samples. The average for the treated positive results was 9.3 pCi/L.LLD sensitivities for the remaining 21 samples were <2 to<3 pCi/L. The maximum preoperational level detected was 1.4 pCi/L. There was no preoperational average determined for this analysis.

The higher results in the three measurable samples are due to the procedural change for sample preparation, as discussed in the Well Water section.11 Vegetables (Table C-10)Although vegetables in the region are not irrigated with water into which liquid plant effluents have been discharged, a variety of food products grown in the area for human consumption were sampled at 5 indicator stations (15 samples) and 4 control stations (12 samples).The vegetables collected as management audit samples were analyzed for gamma emitters and included asparagus, cabbage, sweet corn, peppers, and tomatoes.Gamma spectroscopy performed on each of the 27 samples indicated the presence of the naturally-occurring radionuclide K-40 and in one sample radium. All other gamma emitters searched for were below the LLD.Potassium-40 was detected in all 27 samples. Concentrations for the 15 indicator station samples ranged from 1240 to 2880 pCi/kg-wet and averaged 2030 pCi/kg-wet.

Concentrations for the 12 control station samples ranged from 1180 to 2860 pCi/kg-wet, and averaged 1930 pCi/kg-wet.

The average concentration detected for all samples, both indicator and control, was 1980 pCi/kg-wet.

Game (Table C-11)Although not required by the SGS or-'HCGS Technical Specifications/ODCM, samples of muskrats inhabiting the marshlands surrounding the Site, are collected.

Local residents consume this game. Thesamples, when available, are collected once a year as management audit samples and analyzed for gamma emitters.Gamma spectroscopy performed on the flesh indicated the presence of the naturally-occurring radionuclide K-40. All other gamma emitters searched for'were below the LLD.Potassium-40 was detected in the one sample at a concentration of 2970 pCi/kg-wet.

The maximum preoperational level detected was 27000 pCi/kg-wet, with an average of 4400 pCi/kg-wet.

Fodder Crops (Table C-12)Although not required by the SGS or HCGS Technical Specifications/ODCM, 3 samples of crops normally used as cattle feed (silage and soybeans) were collected from one indicator station 12 (1 sample) and one control station (2 samples).

It was determined that these products may be a significant element in the food-chain pathway. These fodder crops are collected as management audit samples and analyzed for gamma emitters.

The two locations from which samples were collected this year are milk sampling stations.In addition to the silage and soybean, ornamental cabbage was planted, maintained, and harvested by MTS personnel at 3 locations on site and 1 in Delaware, at .3.9. miles. These broad leaf vegetation samples were deemed necessary since there are no longer any milk farms operating within the 5 km radius of SGS/HCGS.

The closest milk farm we have is located in Odessa, DE at 4.9 miles.Gamma spectroscopy performed on each of the 3 samples indicated the presence of the naturally-occurring radionuclides Be-7 and K-40.All other gamma emitters searched for were below the LLD.Beryllium-7,.attributed to cosmic ray activity in the atmosphere, was detected in the indicator silage.,sample at a concentration of 283 pCi/kg-wet.

LLD sensitivities for all the fodder crops ranged from <5.9 to <11 pCi/kg-wet.

There was no preoperational data available.for comparison.

AQUATIC Environmental Consulting Services, Inc (ECS) collected all aquatic samples (with the exception of 6S2 shoreline sediment).

13 Surface water samples were collected in new polyethylene containers that were rinsed twice with the sample medium prior to collection.

Edible fish and crabs are taken by net and then processed.

In processing, the flesh is separated from the bone and shell and placed in sealed polyethylene containers and frozen before being transported in ice chests.Sediment samples collected by ECS were taken with a bottom grab sampler and frozen in sealed polyethylene containers before being transported in ice chests. MTS personnel collect location 6S2 shoreline sediment on the beach behind the observation building.Surface Water (Tables C-13, C-14, C-15)Surface water samples were collected monthly at 4 indicator stations and one control'station in the Delaware estuary. One location is at the outfall area (which is the area-where liquid radioactive effluents from the Salem Station are allowed to be discharged into the Delaware River), another is downstream from the outfall area, and another is directly west of the outfall area at the mouth of the Appoquinimink River. Two upstream locations are;in the Delaware River and at the mouth of the Chesapeake and Delaware Canal, the latter being sampled when the flow is from the Canal into the river.Station 12C1, at the mouth of the A2ppoquinimink River, serves as the operational control. [Location 12C1 was chosen because the physical characteristics of this station more. closely resemble those of the outfall area than do those at the farther upstream location (1F2). As discussed in the pre-operational-summary report, due to the tidal nature of this Delaware-River-Bay estuary, there are flow rate variations.

The further the distance from the boundary between the Delaware River and the Delaware Bay (Liston Point), the lower the background levels, the'lower the salinity, lower K-40(AA) and lower cbncentrations of soluble gross beta emitters.]

All surface water samples were analyzed monthly for gross beta, tritium and gamma emitters.* Gross beta activity was detected in all of the indicator station samples ranging from 6.2 to 143 pCi/L, with an average of 62 pCi/L.

17 PROGRAM DEVIATIONS The following air sampler was unavailable due to power loss: STATION LOCATION HOURS UNAVAILABLE 5S1 1.0 mi. E of vent 232.7 (2.7% for year)Two air particulate samples and two air iodine samples were lost (See Tables C-2 and C-3 in Appendix C). This power outage was attributable to a trip of Island Ring Bus Infeed Breaker #8031 on September 9 th* Repairs were completed by Salem Maintence Department on September 18t. Overall availability for this air sampling location was 97.3t for the year 2005.The TLD package from location 16G1 (across from Greater Wilmington Airport) was lost during the 4th quarter, 2005. The utility pole that the TLD had been stapled to was removed and disposed of with the TLD not recovered.

Inquiries were made to Delmarva and it was discovered that a severe windstorm in late November took out 7 poles in a row at our location along the highway. It took 72,hours to restore power to these poles with emergency Mutual Aid from several other utilities and contractors.

In the confusion, our TLD plus the large laminated neon sign (requesting the finder to call MTS in case of removal) was overlooked and lost.CONCLUSIONS The Radiological Environmental Monitoring Program for Salem and Hope Creek Generating Stations was conducted during 2005 in accordance with the SGS and HCGS Techlnical Specifications/ODCM.

The LLD values required by the Technical Specifications/ODCM were achieved for this reporting period. The objectives of the program were also met during this period. The data collected assists in demonstrating that SGS and HCGS were operated in compliance with Technical Specifications/ODCM.'

From the results obtained, iFt can be concluded that the levels and fluctuations of radioactivity in environmental samples were as expected for an estuarine environment.

No unusual radiological characteristics were observed in the environs of SGS/HCGS during this reporting period. Since these results were comparable to the results obtained during the'preoperational phase of the program, which ran from 1973 to 1976, and with historical results collected since commercial operation, we can conclude that the operation of the Salem and Hope Creek Stations had no significant impact on the radiological characteristics of the environs of that area.18 TABLE 1 SALEM AND HOPE CREEK GENERATING STATIONS RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM (Program Overview)EXPOSURE PATHWAY AND/OR NUMBER OF REPRESENTATIVE SAMPLES AND SAMPLING AND SAMPLE SAMPLE LOCATIONS COLLECTION TYPE/FREQUENCY*

This is due to the distance from Liston Point, which is-the boundary between the Delaware River and Delaware Bay. As discussed extensively in the SGS/HCGS Pre-operational reports, the sampling locations further upstream show significantly lower background levels due to estuarine tidal flow plus lower X40 and Beta Aotiviity.

APPENDIX B SAMPLE DESIGNATION AND LOCATIONS 39 APPENDIX B SAMPLE DESIGNATION The PSEG's Maplewood Testing Services identifies samples by a three part code. The first two letters are the program identification code. Because of the proximity of the Salem and Hope Creek Stations a common environmental surveillance program is being conducted.

The identification code, "SA", has been applied to Salem and Hope Creek stations.

The next three letters are for the media sampled.AIO = Air Iodine APT = Air Particulate ECH = Hard Shell Blue Crab ESF = Edible Fish ESS = Sediment FPL = Green Leafy Vegetables FPV = Vegetables (Various)GAM = Game (Muskrat)IDM =MLK =PWR =PWT =SOL =SWA =VGT =WWA =Immersion Dose (TLD)Milk Potable Water (Raw)Potable Water (Treated)Soil Surface Water Fodder Crops (Various)Well Water The last four symbols are a location code based on direction and distance from a standard reference point. Of these, the first two represent each of the sixteen angular sectors of 22.5 degrees centered about the reactor site. Sector one is divided evenly by the north axis and other sectors are numbered in a clockwise direction; e.g., 2=NNE, 3=NE, 4=ENE, etc. The next digit is a letter which represents the radial distance from the reference point: S = On-site location A = 0-1 miles off-site B = 1-2 miles off-site C = 2-3 miles off-site D = 3-4 miles off-site 4-5 miles off-site 5-10 miles off-site 10-20 miles off-site>20 miles off-site The last number is the station numerical designation within each sector and zone; e.g., 1,2,3,...

For example, the designation SA-WWA-3E1 would indicate a sample in the Salem and Hope Creek program (SA), consisting of well water (WWA), which had been collected in sector number 3, centered at 450 (north east) with respect to the reactor site at a radial distance of 4 to 5 miles off-site, (therefore, radial distance E). The number 1 indicates that this is sampling station #1 in that particular sector.41 TABLE B-1 SAMPLING LOCATIONS Specific information about the individual sampling locations are given in Table B-1. Maps B-1 and B-2 show the locations of sampling stations with respect to the Site. A Portable Global Positioning System (GPS) was used to provide the coordinates of sampling locations.
