For reporting and calculation of averages, any.result occurring at or below the LLD is considered to be at that limit.
Grab sampling is a useful and acceptable procedure for taking environmental samples of a medium in which the concentration of radionuclides is expected to vary slowly with time or where intermittent sampling is deemed sufficient to establish the radiological characteristics of the medium. This method, however, is only representative o.f the sampled medium for that specific location and instant of time. As a result, variation in the radionuclide concentrations of the samples will normally occur. Since these variations will tend to counterbalance one another, averages based upon repetitive grab samples is considered valid. QUALITY ASSURANCE PROGRAM MTS has a quality assurance program designed to ensure confidence.in the analytical program. Approximately 20% of the total analytical effort is spent on quality control, including process quality 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 Services 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 5

As a result, variation in the radionuclide concentrations of the samples will normally occur.
These results are listed in Tables D-1 through D-3 in Appendix D. PROGRAM CHANGES Some' analyses not specifically required by the Salem and Hope Creek Technical Specifications were removed from the 1997 REMP. These include: Iodine-131 in well water; strontium analysis in milk, sediment, crab and all but one fish location.
Since these variations will tend to counterbalance one another, averages based upon repetitive grab samples is considered valid.
A new control location (14Gl), was installed and tested for addition to our REMP program. A shoreline sediment sampling location (6S2) was added to provide more complete coverage of aquatic sediments.

* CONCLUSIONS The Radiological Environmental Monitoring Program for Salem and Hope Creek Generating Stations was conducted during 1997 in accordance with the SGS and HCGS Technical Specifications.
 
The LLD values required by the Technical Specifications 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.

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.
I. ATMOSPHERIC 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, we can conclude that the operation of SGS and HCGS had no significant impact on the radiological characteristics of the environs of that area. 17 MEDIUM I.

SlJMlVIARY During normal operations of a nucl.ear power generating station there are releases of small amounts o_f 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 wheJ:-e the Salem Generating Stations (SGS) and Hope Creek Generating StC:ti:.iow. (;;-;.cc;s; =-:c~ i.>..--:2ted. The results of the .REMP are published annually, providing a summary and interpretatioH of the data collected.

PSE&G's Maplewood Testing Services (MTS) has been responsible for the collection and analysis of environmental samples during the period of January 1, 1997, through December 31, 1997, and the results are discussed in this report. The REMP for SGS/HCGS was conducted in accordance with the SGS and HCGS Technical Specifications. The Lower Limit of Detection (LLD) values required by the Technical Specifications 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.

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

.. which ran from 1973 to 1976, 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 (Section 3/4.12.1), samples were analyzed for one or more of the following:

gamma emitting isotopes, tritium (H-3), strontium-89 (Sr-89) and 90 (Sr-90), 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 (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 1261 analyses on 981 environmental samples during 1997. Direct radiation dose measurements were also made using 199 thermoluminescent dosimeters (TLDs) .
  • In addition to the detection of naturally-occurring isotopes (i. e. Be-7, K-40, Ra-226 and Th-232) trace levels of Co-60, Cs-134, 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 Artificial Island averaged 50 millirems for the year 1997. The average dose measurements at the control locations (background) was 54 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.

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 1115 MWe and Salem Unit Two has a net rating of 1139 Mwe. The licensed core power for both units is

~"1 l l MWt. HC~S is a boiling water nuclear power reactor which has a net rating of 1067 MWe* (3~.93 1..tt~L:J .

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 REMP has been conducted at the SGS/HCGS 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. PSE&G'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, Duke Engineering Services Environmental Laboratory (DESEL) is the third party QA vendor. MTS reports for the operational phase from 1983 to 1996 are referenced in this report [10] .

An overview of the 1997 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 perioqs were examined statistically to determine the effects of station operations. This report presents the results from January 1 through December 31, 1997, 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 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 and Section 6.9.1.6 of the Hope Creek Technical Specifications, summarizes the findings of the 1997 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 organis~m~s~.'..__,-~T~h~e'-=--~~~~

selection of samples was based-en-:--01~,-e-staoITsnea 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 estuarine 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 6.9.1.10 of the Salem TS and Section 6.9.1.7 of the Hope Creek TS, the operational program as performed in 1997. 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 INT~RPRETATION

  • 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 ~hould 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 detec~ed with 95% probability, with only 5% probability of falsely concluding that a blaui<... ubst=:i:"~V-<A:~i.;:;~::, ~~:;,::.:;_*e,s.-:-*n:::s c. i*r2al signal". LLD is normally calculated as 4.66 times one standard deviation of the background count, or of the blank sample count, as appropriate. The Minimum Detectable Concentration (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 grouped data were averaged and standard deviations calculated in accordance with Appendix B of Reference 17. 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 limit.

When a group of data was composed of 50% or more LLD values, averages were not calculated.

Grab sampling is a useful and acceptable procedure for taking environmental samples of a medium in which the concentration of radionuclides is expected to vary slowly with time or where intermittent sampling is deemed sufficient to establish the radiological characteristics of the medium. This method, however, is only representative o.f the sampled medium for that specific location and instant of time. As a result, variation in the radionuclide concentrations of the samples will normally occur.

Since these variations will tend to counterbalance one another, averages based upon repetitive grab samples is considered valid.

QUALITY ASSURANCE PROGRAM MTS has a quality assurance program designed to ensure confidence.in the analytical program. Approximately 20% of the total analytical effort is spent on quality control, including process quality 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 Services 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 5

procedures and computer program~, .and analysis of duplicate and spiked samples. The external qualrt¥ control activity is implemented through participation in the USEPA and Analytics Inter-laboratory Comparison Programs. These results are listed in Tables D-1 through D-3 in Appendix D.

PROGRAM CHANGES Some' analyses not specifically required by the Salem and Hope Creek Technical Specifications were removed from the 1997 REMP. These include: Iodine-131 in well water; strontium analysis in milk, sediment, crab and all but one fish location. A new control location (14Gl), was installed and tested for addition to our REMP program. A shoreline sediment sampling location (6S2) was added to provide more complete coverage of aquatic sediments.

RESULTS AND DISCUSSION

'

The analytical results of the 1997 REMP samples are divided into categories based on exposure pathways: atmospheric, direct, terrestrial, and aquatic. The analytical results for the 1997 REMP are summarized in Appendix A. The data for individual samples are presented in Appendix C. The data collected demonstrates that SGS and HCGS were operated in compliance with Technical Specifications.

The REMP for the SGS/HCGS Site has historically included samples and analyses not specifically required by these Station's Technical Specifications. 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. Iodine was collected from the air by adsorption on triethylenediamine (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 at 6 locations. Each of the 318 weekly samples collected 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 sampling stations in 1997 was 98.2 percent.

' 0 Radium was detected in 1 indicator station sample at a concentration of 1. 2 x 10- 3 pCi/m3 but not in any of the control station samples. LLD sensitivities for the remaining sample locations, both indicator and control, ranged from <0. 2 x 10- 3 to <0. 9 x 10- 3 pCi/m3

  • No preoperational data is available for comparison.
  • .;;

Air Iodine (Table C-3)

Iodine in filtered air samples was collected at 6 locations. Each of the 318 weekly samples collected was analyzed for I-131.

Iodine-131 was not detected in any of the 318 weekly samples analyzed. LLD sensitivities for all the stations, both indicator and control, ranged from <l. 0 x 10- 3 to <9. 9 x 10- 3 pCi/m3

  • The maximum preoperational level detected was 42 x 10- 3 pCi/m3
  • DIRECT RADIATION Ambient radiation levels in the environs were measured with energy-compensated CaS0 4 (Tl) thermoluminescent dosimeters (TLDs) supplied and read by DESEL. Packets containing TLD's for quarterly exposure were placed in the owner controlled area and around the Site at various dista~ces.

Direct Radiation (Table C-4)

A total of 50 locations were monitored for direct radiation during

'1997, including 12 on-site locations, 31 off-site locations within the 10 mile zone, and 7 control locations beyond 10 miles. Effort was made to locate TLD's 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, and the average control *rate was 4.5 millirads per standard month. The preoperational average for the quarterly TLD readings was 4.4 millirads 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 1974 through 1997.

I 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.new polyethylene containers and transported in ice chests with no preservatives added.

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 are collected once a year at time of harvest. Such samples are weighed and packed in plastic bags. Grass/green chop is collected from grazing areas, where possible.

Game (muskrat) is 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 are 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 the 60 indicator station samples ranged from <0.1 to <0.4 pCi/L and for the 20 control station samples from <0.1 to <0.4 pCi/L. The maximum preoperational level detected was 65 pCi/L which occurred following a period of atmospheric nuclear weapons tests.

  • Gamma spectroscopy performed on each of the 80 samples indicated the presence of the naturally-occurring radionuclides K-*10 2nd Re<"Hum. 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 1240 to 1550 pCi/L, with an average of 1400 pCi/L. The 20 control station sample concentrations ranged from 1230 to 1490 pCi/L, with an average of 1400 pCi/L. The maximum preoperational level detected was 2000 -pCi/L, with an average of 1437 pCi/L.

0 Radium was detected in only 1 of the indicator samples at a concentration of 12 pCi/L. It was not detected in any of the control station samples. LLD sensitivities for the remaining sample locations, both indicator and control, ranged from <1.9 to <9.2 pCi/L. The maximum preoperational level detected was <30 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.

  • Gross alpha activity was detected in 11 of the well water samples at concentrations ranging from 1.4 to 3.0 pCi/L and an average of 2.1 pCi/L. The maximum preoperational level detected was 9.6 pCi/L. There was no preoperational average determined for this analyses.
  • Gross beta activity was detected in all 12 well water samples.

Concentrations for the samples ranged from 3.2 to 11 pCi/L, with an average of 10 pCi/L. The 3.2 pCi/L result was investigated because it was lower than the typical value.

Since some of the beta emitters found in water samples are also gamma emitters, the gross gamma results were reviewed for the same sample set. This review showed the lowest total gamma activity was found in the same sample exhibiting the lowest gross beta activity. The 1997 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 detected in only 1 of the well water samples at a concentration of 200 pCi/L.

9

The LLD sensitivities ranged from <140 to <160 pCi/L. The maximum preoperational level detected was 380 pCi/L.

  • 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.

0 Radium was detected in all 12 of the well water samples at concentrations ranging from 59 to 258 pCi/L with an average of 128 pCi/L. The maximum preoperational level detected was 2.0 pCi/L.

These values are similar to those found in the past several years. However, as with the 1989 through 1996 results, they are higher than those found in the preoperational program.

We believe that results are higher due to a procedural change in which the samples are no longer boiled down to a 100 ml standard geometry. This change results in less removal of radon (and its daughters) from the sample. Since Ra-226 is an alpha emitter, its identification by gamma isotopic analysis is obtained by counting the gamma rays from Pb-214, one of its daughter products. It is reasonable to assume that values currently being observed are typical for this geographical area.

0 Potassium-40 was detected in 2 of the samples with an average of 59 pCi/L. The maximum preoperational level detected was 30 pCi/L.

Potable Water (Drinking Water) (Tables C-8, C-9)

Both raw and treated potable water samples were collected from the Salem water treatment plant. Each sample consisted of daily aliquots composited into a monthly sample. The raw water source for this plant is Laurel Lake and adjacent wells. Each of the 24 individual samples was analyzed for gross alpha, gross beta, tritium, iodine-131 and gamma emitters.

m Gross alpha activity was detected in 11 raw water samples at concentrations of 0.7 to 1.6 pCi/L and in 4 treated water samples ranging from 0.9 to 1.6 pCi/L. The averages for both raw and treated water samples was 1.2 pCi/L. The maximum pre-operational level detected was 2.7 pCi/L.

  • Gross beta activity was detected in all 24 samples at concentrations ranging from 1.7 to 3.8 pCi/L for both the raw and treated water. The average concentration for both raw and treated was 2.6 pCi/L. The maximum preoperational level detected was 9.0 pCi/L, with an average of 4.2 pCi/L.

  • CONCLUSIONS The Radiological Environmental Monitoring Program for Salem and Hope

'

Creek Generating Stations was conducted during 1997 in accordance with the SGS and HCGS Technical Specifications. The LLD values required by the Technical Specifications 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.

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

,. which ran from 1973 to 1976, we can conclude that the operation of SGS and HCGS had no significant impact on the radiological characteristics of the environs of that area.

APPENDIX B SAMPLE DESIGNATION AND LOCATIONS

'

39

APPENDIX B SAMPLE DESIGNATION The PSE&G Maplewood Testing Services identifies samples part code. The first two* letters are .the 'power station identification code, in this case "SA". The next three letters are for the media sampled.

AIO = Air Iodine IDM  :::: Immersion Dose (TLD)

APT Air Particulates MLK Milk

  • ECH = Hard Shell Blue Crab PWR  :::: Potable Water (Raw)

ESF = Edible Fish PWT  :::: Potable Water (Treated)

.ESS Sediment RWA  :::: Rain Water (Precipitation)

FPB = Beef SOL  :::: Soil FPL = Green Leafy Vegetabl*es SWA  :::: Surf ace Water FPV Vegetables (Various) VGT Fodder Crops (Various)

GAM = Game (Muskrat) WWA Well Water The last four symbols are a location code based on direction and distance from the site. 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; i.e., 2=NNE, 3=NE, 4=ENE, etc. The next digit is a letter which represents the radial distance from the plant:

S On-site location E 4-5 miles off-site A 0-1 miles off-site F = 5-10 miles off-site B 1-2 miles off-site G 10-20 miles off-site C = 2-3 miles off-site H >20 miles off-site D 3-4 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-3El would indicate a sample in the SGS program (SA),

consisting of well water (WWA), which had been collected in sector number 3, centered at 45° (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.

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 Trimble Portable Global Positioning System (GPS) was used to provide the coordinates of sampling locations.
