1.0 INTRODUCTION

1-1 J20AREOR850306 1

INTRODUCTION Grand Gulf Nuclear Station (GGNS), located in Claiborne County, Mississippi, consists of one operating boiling water reactor rated at 1250 MWe and a similar unit under construction. The site is on the east bank of the Mississippi River, approxi-4 mately 25 miles south-southwest of Vicksburg, Mississippi, and 37 miles north-northeast of Natchez, Mississippt. Grand Gulf 4 Military Park borders a portion of the north side of the property, and the community of Grand Gulf is approximately 1.5 miles to the north. The town of Port Gibson is approximately 6 miles southeast of the site. Two lakes, Hamilton Lake and Gin Lake, are located in the western portion of the site. 1.1 PURPOSE AND DESIGN CRITERIA 0F THE RADIOLOGICAL ENVIRONMENTAL SURVEILLANCE PROGRAM Grand Gulf Nuclear Station has been designed to keep radioactive releases as low as reasonably achievable. The quantities of radionuclides released to the environment due to the operation of GGNS are expected to be insignificant as a source of potential exposure. The purposes of the Radiological Environmental Surveillance Program are: o To measure radiation levels and their variations in envircamental media in the area surrounding the plant o To yield average values of radiation levels and concentrations of radioactive material in various media of the environment

    ,        o   To evaluate environmental procedures, equipment, and techniques J20AREOR850306 1

o To detect what effect, if any, operation of GGNS will have on the radiation levels and concentrations in the environment around GGNS.

               .The design criteria for the Radiological Environmental Surveillance Program are:

o To analyze the important pathways for anticipated types and quantities of radionuclides released from the station into the surrounding environment o To consider the possibility of a buildup of long-lived radionuclides in the environment and identify physical and biological sites of accumulation that may contribute to human exposures o To consider the potential radiation exposure to important plant and animal life in the environment surrounding GGNS , o To correlate levels of radiation and radioactivity in the environment with radioactive releases from station operation. 1.2 DOSE PATHWAYS ASSOCIATED WITH GGNS The most significant environmental dose pathways from a nuclear power station are direct dose from gaseous effluent and thyroid dose due to the ingestion of milk. GGNS operations are expected to have little, if any, impact on these pathways due to the remote location of the station and the absence of milking animals within 5 miles. Also, since the first use of Mississippi River water as drinking water is more than 200 miles downstream of GGNS, the dose from this pathway is expected to be minimal. J20AREOR850306 2

1.3 HISTORY OF OPERATION AND PRESENT STATUS GGNS Unit I received a Low-Power Operating License on June 16, 1982. Fuel loading began on July 1, 1982 and was completed on August 6, 1982. Initial criticality was achieved on August 18, 1982. Low-power testing began on September 25, 1983 and was discontinued on November 8, 1983 with 995.3 hours of operation at less than 5 percent power recorded for Unit 1. Low-power testing was resumed on April 22, 1984 and ccmpleted shortly thereafter. The Full-Power Operating License was granted on August 31, 1984, and commercial operation began on July 1, 1985. The following list summarizes significant dates associated with the operation of Unit 1: o Low-Power Operating License June 16, 1982 o Initial Criticality August 18, 1982 o Began Low-Power Testing September 25, 1983 o Discontinued Low-Power Testing November 8, 1983 o Resumed Low-Power Testing April 22, 1984 o Full-Power Operating License August 31, 1984 o Startup After Full-Power License September 5, 1984 o First Synchronization October 20, 1984 o Commercial Operation July 1, 1985.

1 GGNS Unit 2 is in a construction phase and was approxi-  ; f mately 33.8% complete as of December 31, 1985. The minimal Unit 2 construction activities occurring in 1985 were for the purpose of protecting the original investment. Preoperational Study The Preoperational Radiological Environmental ,

                                                                 \

Surveillance Program was initiated in July 1978. It was continued until GGNS received its Low-Power Operating License for Unit 1 on June 16, 1982. The background data gathered [! during the Preoperational Program was included in the 1982 Annual Radiological Environmental Operating Report. 1982 Annual Radiological Environmental Operating Report (AREOR) GGNS Unit I received a Low-Power Operating License on June 16, 1982. During 1982 Unit 1 did not enter a power ascension mode. Therefore, the results of the Operational Environmental Surveillance Program from June 16, 1982 to December 31, 1982 are actually an extension of the preoperational program data. Thedatawaspresentedinl Tables 8 through 12 of the 1982 AREOR. , 1983 AREOR Unit 1 of GGNS saw 995.3 hours of low-power operation between September 25 and November 8, 1983. Based on the i results of the Radiological Environmental Surveillance Program, GGNS had no effect on the radiation levels in the environs surrounding the site. J20AREOR850306 4 -

1984 AREOR A comparison of the 1984 Radiological Environmental Surveillance Program results with those of previous years showed no changes. The 1984 radiation monitoring levels did j not exceed the background levels obtained in the f Preoperational Program. No harmful effects or evidence of irreversible damage were detected by 1984 Radiological i Environmental Surveillance Program monitoring activities. l, GGNS Technical Specifications were revised on August 29,  ! i- 1984 to more accurately reflect the as-built plant and to i i i i provide greater agreement with standard nuclear power plant ' t F technical specifications. The revisions which affected the Radiological Environmental Surveillance Program are 3 summarized below: o Required air sampling locations are now based on t particulate deposition rates ir. stead of atmospheric dispersion rates. This added locations AS-6 and -8 and , ' deleted AS-4 and -9 from the 5 locations required by ' technical specifications. o Fish sampling requirements have been broadened to include any available commercial or recreational species. o An additional vegetation sampling site is now required  :

c o Land use census requirements were expanded to include determination of the nearest resident, milk animal and garden in each of the 16 meteorological sectors instead of just the nearest resident, garden and milk animal ' locations. , o TLD placement is no longer required in meteorological sectors which are inaccessible. Full implementation of the revised technical specification a requirements began in September 1984. 1985 AREOR

The required operational testing of GGNS was completed during the first half of 1985. Commercial operation of GGNS 4

began on July 1, 1985. This was the first year that GGNS had substantial operational activity. Radiological environmental sample results for 1985 were ! carefully reviewed by Environmental Surveillance Program personnel for significant changes. Slight increases above back-ground levels were noted.in sediment sample results from the GGNS barge slip. This occurrence is discussed in Section 4.6. Other sample results were essentially at preoperational levels with no significant changes. Based on the review of 1985 sample results, Environmental Surveillance Program personnel concluded that the operation of GGNS had no adverse radiological impact on the surrounding environment. o , L r

O J20AREOR850306 1

2.1 AIR PARTICULATES AND RADI0 IODINES The GGNS Environmental Surveillance Program utilizes eleven continuous air monitors to provide beta, gamma and radioiodine activity measurements in the airborne exposure pathway. The locations of these monitors range from 0 to 18 miles, as identified in Figures 2-1 through 2-3 and Table 2-1. Five of the air samplers are used to satisfy the requirements of GGNS Technical Specification 4.12.1. Placement of the five required monitors are as follows: o Three near the SITE BOUNDARY in areas of the highest D/Q values o One in a community that has the highest D/Q value (Port Gibson) o One in a control location (Vicksburg). The remaining six samplers are located in areas which will provide additional data for the Radiological Environmental Surveillance Program. The samplers are placed in weatherproof houses approximately one meter above the ground. A 2-inch glass fiber filter is located in the intake line of the vacuum pump with a 2 x l-inch charcoal cartridge located directly downstream. Flows are adjusted to approximately 1.25 cubic feet per minute. Filters and cartridges are changed weekly and analyzed for gross beta and radiciodine activity, respectively. In addition, the filters are composited quarterly and analyzed for gamma-emitting radionuclides. J20AREOR850306 1

2.2 THERM 0 LUMINESCENT DOSIMETRY (TLD) Ambient radiation in the environment surrounding GGNS is measured with 91 TLDs (lithium fluoride dosimeters, 1/8" x 1/8" x 0.035" chips, TLD-100, Harshaw Chemical Company). ,. Maps showing the location of the environmental TLDs are provided as Figures 2-1 through 2-3. Each dosimeter has five lithium fluoride chips sealed in a plastic protective holder. The holder is suspended approximately one meter above the ground at each location. The dosimeters are collected quarterly, with notations made concerning location, exposure period, and any abnormal conditions such as moisture and damage. The 91 TLD locations are defined in Table 2-2. The criteria used in selecting their locations are summarized below: o GGNS Technical Specification 4.12.1 requires 40 of the 91 TLDs to be positioned as outlined below: An inner ring of 16 stations in the general area of the site boundary with one TLD in each meteorological sector An outer ring of 16 stations in the 3 to 5 mile range with one TLD in each meteorological sector 8 TLDs located in special interest areas such as l population centers and residences or utilized as ~ controls, o Permanent TLD stations are established on the protected area fence surrounding Unit 1. This requires 24 of the 91 TLDs. I o The remaining 27 TLDs are located in areas ranging from l 0-15 miles away from the GGNS site. These TLDs are used to gather supplemental and supporting data for determining direct radiation dose. l J20AREOR850306 2

GGNS Technical Specifications require semimonthly milk sampling at three indicator locations within eight kilometers of the site and one control location (15-30 kilometers distant) when animals are on pasture, monthly at other times.

No milk animals are available within eight kilometers of GGNS. A control sample is collected routinely from the Alcorn State University Dairy to establish background data. In previous years, milk samples have occasionally been collected from three area farmers (Figure 2-2, Table 2-3) outside the eight kilometer range. However, in 1985 milk samples were not available at these locations. Collected milk is divided and analyzed for Iodine-131 and gamma-emitting radionuclides. 9 J20AREOR850306 3

l l 2.4 WATER Water samples are collected in the vicinity of GGNS for the measurement of radioactivity in the waterborne exposure pathway. Samples are collected in clean, labelled 2.5-gallon containers. The containers are rinsed with the sample media prior to collection. Cistern water is sampled monthly at two locations, one near the site (Trimble Cistern) and the other at a control location (Willis Cistern) (Figure 2-1, Table 2-3). Cistern water is analyzed for gross beta, Iodine-131 and gamma-emitting radionuclides. In addition, a quarterly composite is analyzed for tritium. Groundwater is sampled at three locations. The locations fulfilling the Technical Specifications are the source nearest the site (Grand Gulf Military Park (GGMP) Well) and the control (Port Gibson City Well). The other location (Lake Bruin State Park) provides GGNS with additional data (Figures 2-1 and 2-2, Table 2-3). Ground-water is collected and analyzed quarterly for gamma-emitting radionuclides and tritium. Surface water samples from the Mississippi River are collected monthly at a point upstream and downstream of the plant discharge (Figure 2-4, Table 2-3). They are analyzed monthly for gamma-emitting radionuclides and a composite is analyzed quarterly for tritium. J20AREOR850306 4

l An additional surface water sample is taken from the GGNS Discharge' Basin. Samples are composited monthly from , samples taken at hourly intervals with an automatic sampler. This sample is analyzed for gamma-emitting radionuclides monthly and a composite analyzed quarterly for tritium. ! 2.5 VEGETATION Broadleaf vegetation samples are collected in the vicinity of GGNS for the purpose of measuring radioactivity

 !                    via the ingestion exposure pathway.                       Three samples of i

broadleaf vegetation grown nearest each of two different

offsite locations with the highest anticipated annual average ground-level D/Q are required when milk samples are not

] available within five kilometers of the site boundary. The i second offsite sampling location was not required until the GGNS Technical Specifications were revised on i August 29, 1984. ! Environmental Surveillance Program personnel meet this i requirement by maintaining two gardens inside the SITE BOUNDARY. These sampling locations (Figure 2-1, Table 2-4) i , provide a more conservative assessment of doses due to the potential ingestion of contaminated vegetation than would be provided by offsite sampling locations. Control samples of each of the similar types of onsite vegetation are also obtained 15-30 kilometers from the site. l A control vegetation sample location was established at Alcorn State University (Sector K, 17 km) in 1984. t i !

The preferred source'of broadleaf vegetation is green-leafy vegetables suitable for human consumption. If such vegetables are not available, samples of any vegetation with relatively broad-leaves on which airborne radioactive material might be deposited are sampled. The raw samples are then analyzed for gamma-emitting radionuclides and Iodine-131. 2.6 SEDIMENT Sediment samples are collected semiannually at the following locations (Figure 2-1, Table 2-4): o River shoreline where the plant effluent is discharged (Barge Slip) o Downstream of the barge slip in the vicinity of-the Hamilton Lake Outfall o Upstream from the influent of GGNS discharges (Upper Grand' Gulf Landing). The only sediment sample required by GGNS Technical Specifications is the downstream location. Sediment samples are collected in the shallow water near the shoreline from the top one-inch layer of sediment. Any foreign objects are discarded and the samples are placed in a-sample container with location and date noted. The samples are then analyzed for gamma-emitting radionuclides including Cesium-137. l J20AREOR850306 6

2.7 FISH Fish are collected semiannually from two locations. The control fish sample is collected in the Mississippi River about 1000 yards upstream from the GGNS barge slip. The indicator sample is collected approximately 6000 feet downstream from the barge slip. A minimum of 500 grams (wet weight) of eviscerated fish is collected from each location (Figure 2-1, Table 2-4) and analyzed for gamma-emitting radionuclides. 2.8 SPECIAL SAMPLES Special samples are occasionally taken from sampling media or locations which are not part of the routine Environmental Surveillance Program. Sample media may include sediment, water, milk, fish, meat and vegetation. Special samples are collected to provide supplementary data and to address areas of special interest. Deer meat is a special sample which is periodically obtained from deer harvested on or adjacent to the GGNS site. The meat is then analyzed for gamma-emitting radionuclides, particularly Iron-59 and Zinc-65. 2.9 ANNUAL LAND USE CENSUS As required by GGNS Technical Specification 3.12.2, Environmental Surveillance Program personnel conduct an Annual Land Use Census. The purpose of the census is to J20AREOR850306 7

identify changes in the uses of land in the unrestricted areas surrounding GGNS which would require modifications to the Radiological Environmental Surveillance Program or the Offsite Dose Calculation Manual (ODCM). The most important criteria during the census are to determine the location in each of the 16 meteorological sectors of the nearest: o Residence o Animal milked for human consumption o Garden of greater th'an 50 m2 (500ft2) producing broad-leaf vegetation.

SECTION 3.0 ANALYTICAL PROCEDURES AND COUNTING METHODS J20AREOR850306 1

3.1 ANALYTICAL PROGRAM AND METHODOLOGY Samples are analyzed for the various radioactive components by standard radiochemical methods. Those methods are equal to and in most cases identical with those of the USDOE (HASL Procedures Manual, HASL-300, Health and Safety Laboratory, U. S. Atomic Energy Commission, 376 Hudson Street, New York, New York 10074), or those of the U. S. I Department of Health. The analytical program is summarized in Table 3-1. 3.2 ANALYTICAL DETECTION LIMITS AND COUNT RATE ERRORS In environmental radiological analyses the dominant known uncertainty is usually the sample count rate. Error terms given in this report are based on this factor since all other analytical uncertainties are calculated by standard methods and are reported at the 95 percent (2 sigma) confidence level. Analytical data for samples for which concentrations are less than the Lower Limit of Detection (LLD) are preceded by the symbol " < ". The sample types, analyses performed and units of the measurements along with the corresponding required LLD,'.are presented in Table 3-2. 3.3 AIR PARTICULATES Gross beta concentrations are measured with low back-I ground gas flow proportional counting systems with anti-coincidence background suppression after the short-lived naturally occurring radon and thoron daughters have decayed.

The filters are counted long enough to ensure that the required sensitivity (LLD) is met. The required LLD is 0.01 pCi/m 3 for gross beta based on about 300 m / 3 week of air volume. Gamma isotopic analyses of the quarterly composite samples are performed with a Ge(Li) or GeHP detector with required LLDs as listed in Table 3-2. 3.4 RADIOIODINE The charcoal cartridges used are of the TEDA-impregnated type. The samples are analyzed for I-131 gamma-spectroscopically using Ge(Li) or GeHP detectors. The required LLD is 0.07 pCi/m 3, 3.5 CISTERN WATER Gross beta analysis of cistern water is performed by evaporation of a measured aliquot of the sample, digestion, planchetting of the processed sample and radiometric assay by low-level beta counting. The required LLD is 4 pCi/ liter. Iodine-131 analysis is based on anion exchange removal of the I-131 from a known sample volume. The iodine is

eluted from the resin with Na0Cl which also oxidizes it to the iodate. The iodate is reduced to iodine with hydroxylamine in 3N nitric acid solution. The iodine is i extracted into carbon tetrachloride, reduced to iodide with sodium bisulfite, extracted into water and precipitated as PdI .

2 The sample is filtered, dried, weighed and beta counted. The required LLD is 1 pCi/ liter. J20AREOR850306 2

Gamma isotopic analysis is performed by taking a measured aliquot of the sample and counting it in a standard geometry in a high resolution (GeLi or GeHP) gamma spectrometer long enough to meet the required LLDs in Table 3-2. Tritium analyqis is performed on the quarterly composite of the monthly samples. This composite sample is analyzed by liquid scintillation technique. 3.6 SURFACE WATER Monthly samples are analyzed by gamma spectrometry as described in Section 3.5 under Cistern Water. The quarterly composite sample of the monthly collections is analyzed for tritium by the scintillation technique described in Section 3.5 under Cistern Water. 3.7 GROUNDWATER Quc-Serly samples are analyzed for gamma-emitting radionuclides and tritium as described in Section 3.5 under Cistern Water. 3.8 MILK I-131 analysis is performed on the monthly milk samples. The method used is the same as given in Section 3.5 under Cistern Water. Gamma isotopic analysis is performed as described in Section 3.5 under Cistern Water. J20AREOR850306 3

by 2 hours at 100*C and immediate cooling to ambient temperature by placing the tray containing the annealed chips on an aluminum block.

After exposure the chips are pre-annealed for 10 minutes at 100*C and are read on a Harshaw 2000P reader. The system employs a preheat cycle which removes low temperature peaks and integrates and digitizes only the light output in a selected temperature range. The dose is calculated from the average light output for the five readings. Control badges are used to detect any unusual exposure to the badge which might occur during shipment. The LLD for environmental TLDs is 1 mrem / quarter. i e J20AREOR850306 5

I SECTION 4.0 RESULTS AND DISCUSSION J20AREOR850306 1

4.1 AIR PARTICULATES AND RADIOIODINE Air particulate and Iodine-131 results for 1985 were similar to those obtained in previous years for the Operational Program. Results were also comparable to those obtained in the Preoperational Program. This indicates that the airborne exposure pathway has not been affected by the operation of GGNS and that airborne concentrations continue to be at background levels. The gross beta particulate data obtained during 1985 remained at low levels. The levels were in the range expected for this type of medium. The gross beta concentrations for the indicator loca-3 tions were in the range of 0.008 to 0.046 pCi/m with an 3 average value of 0.022 pCi/m and for the control location were in the range of 0.007 to 0.039 pCi/m3 with an average of 3 0.02 pCi/m . Measured levels were in the range expected for this type of medium. Analysis results for individual filters are provided in Table 7-1, 1985 Sampling and Analysis Results. Airborne Iodine-131 concentrations were less than 0.07 pCi/m 3 for all samples received. Analysis results are presented in Table 7-1. The gamma spectrometry data for the quarterly composites of air particulates is also presented in Table 7-1. Results were below the LLDs for this analysis. J20AREOR850306 1

4.2 AMBIENT RADIATION LEVELS (GAMMA DOSE BY TLD) Gamma radiation dose in 1985 was measured with thermoluminescent dosimeters (TLDs) on a quarterly schedule. Three TLD locations showed a significant difference in mean yearly dose rates when compared to 1984 data. Locations M-68, M-69 and M-70 showed mean yearly increases over their 1984 dose rates as summarized below: Location 1984 Dose 1985 Dose Increase  % Increase (mR/Qtr) (mR/Qtr) (mR/Qtr) M-68 16.6 30.2 13.6 81.9 M-69 13.6 34.2 20.6 151.5 M-70 13.2 39.0 25.8 195.4 M-04 Control 20.9 20.3 N/A N/A TLDs M-68, M-69 and M-70 are located on the protected area fence facing the Radwaste Building. The protected area fence TLDs are used to calculate direct radiation dose to the public. As reported in the Semiannual Radioactive Effluent Release Report (SRERR) dated February 26, 1986, the direct radiation dose to the public in 1985 was 8.3 mrem. This was within the limits specified by GGNS Technical Specification 3.11.4. However, it was the first year an increase above background had been observed. Table 4-1 summarizes annual direct radiation dose since 1983. Increased processing and shipping of radwaste in 1985 were responsible for the increased dose rates observed at TLD J20AREOR850306 2

locations M-68, M-69 and M-70. Continued operation of GGNS will result in higher activity in the waste being processed. This in turn will continue to cause individual TLDs to read significantly higher than the average. A more detailed discussion of this anomaly is provided in the SRERR dated February 26, 1986. Other than those mentioned above, there was no significant difference in 1985 dose rates when compared to control values or those from previous years. The 1985 data is presented in Table 7-1. 4.3 MILK No milk samples were available in 1985 within eight kilometers of the GGNS site. Milk samples from the optional locations at the Johnson, Warren and Bell farms were also unavailable in 1985. Only milk samples from the Alcorn control location could be collected and analyzed for Iodine-131 and gamma emitters. Iodine-131 and gamma isotopic concentrations for Alcorn milk samples were below the LLDs. This is generally consistent with data from previous years. The data is presented in Table 7-1. 4.4 WATER Environmental Surveillance Program personnel sampled cistern water, surface water and groundwater as required during 1985. Analysis results were similar to those reported for previous years, with the exception of tritium in Discharge Basin surface water. J20AREOR850306 3

Cistern Water Cistern water samples were collected from two locations and analyzed for gross beta, Iodine-131 and gamma-emitting radionuclides. The gross beta concentrations for the indi-cator location were in the range of 0.8 to 3.4 pCi/l with an average value of 1.9 pCi/1. The control location was in the range of 0.8 to 2.6 pCi/l with an average of 1.3 pCi/1. Measured levels were in the range expected for this type of medium. The I-131 and gamma-emitting radionuclides concentra-tions were below the LLDs. Tritium measurements were made on quarterly composites. Tritium levels were equal to or less than the LLD and were in the range expected for this type of medium. Data collected for cistern water is provided in Table 7-1. Surface Water Surface water samples were collected monthly and analyzed for gamma-emitting radionuclides. Quarterly composites were analyzed for tritium. Gamma isotopic concentrations were below the LLDs for upstream, downstream and Discharge Basin samples. J20AREOR850306 4

Tritium levels for Discharge Basin surface water ranged from 420 pCi/1 to 520 pCi/1 with an average value of 470 pCi/1. The second quarter of 1985 was the first time that tritium was detected in Discharge Basin surface water at GGNS. This activity was attributable'to increased plant operating levels and radwaste discharges in 1985. Tritium levels for upstream and downstream Mississippi River locations were equal to or less than the LLD. Data is presented in Table 7-1. Groundwater Groundwater samples were collected quarterly and analyzed for gamma-emitting radionuclides and tritium. The gamma-emitting radionuclides and tritium levels were below the LLDs. The data is presented is Table 7-1. 4.5 VEGETATION Vegetation samples were collected in 1985 from two onsite locations (Sector J and R) and a control location at Alcorn University. These samples were analyzed for gamma-emmitting radionuclides and I-131. The analysis of October 14, 1985 vegetation samples was performed at the Arkansas Power & Light (AP&L) Environmental Laboratory rather than at the primary contractor Teledyne Isotopes. The October 14 samples sent to Teledyne were lost in shipping, but a duplicate set had been sent to AP&L. J20AREOR850306 5 I

l l Analysis results from AP&L were similar to those received from Teledyne for other vegetation samples. Gamma isotopic and Iodine-131 concentrations measured by both Teledyne and AP&L were below the required LLDs. Results from previous years were also at very low to non-detectable levels. Analysis results from Teledyne and AP&L are included as Tables 7-1 and 7-2, respectively. 4.6 SEDIMENT Sediment samples were collected at least semiannually in 1985 and analyzed for gamma-emitting radionuclides as required by the GGNS Technical Specifications. Sample results from the downstream location, required by GGNS Technical Specifications, and the upstream control were at or below the 3 LLDs. These results were consistent with previous sample results obtained during preoperational and operational sampling. Sediment samples were also collected from the GGNS barge slip. Results from barge slip sediment samples showed a very slight increase over previous sample results. The average and maximum values for barge slip sediment samples were as follows: Radionuclide LLD (pCi/q) Avg. (pCi/g) Max. (pCi/g) Cesium - 134 0.15 < 0.15 < 0.15 Cesium - 137 0.18 0.19 0.24 Cobalt - 58 0.15 0.34 1.05 Cobalt - 60 0.15 0.40 0.69 Manganese - 54 0.15 1.15 2.62 J20AREOR850306 6

Samples collected from the barge slip location in previous years have been below the required LLDs. Liquid radioactive effluents from GGNS are mixed with the cooling tower blowdown and discharged into the Mississippi River via the barge slip. Considering the predicted annual average concentrations of radionuclides in liquid plant effluents for two unit operation (F'inal Environmental Report, Table 5.2.1), an increase in  ! radionuclides in the barge slip sediment is understandable. As reported in past Semiannual Radiological Effluent Release Reports (SRERRs) cobalt and manganese radionuclides have been present in GGNS effluents, but Cesium-137 has not been identified in SREERs. Possibly Cesium-137 was below the required LLD (5 x 10-7 pCi/ml) and was not detected. However, none of these radionuclides were detected in dis-charge basin composite water samples, confirming that GGNS is meeting all specified release limits and parameters. The presence of these radionuclides in barge slip sediments may be attributable to build up of very small amounts of sediment over a period of time. The effluent water velocity decreases in the barge slip and this would promote settling of small particles. Radionuclide concentrations at the levels detected in barge slip sediment are not a threat to human health or the environment. Concentrations are well below the unrestricted

               . release limits described in 10CFR20, Appendix B, Table 2, Column 2. Barge slip monitoring will continue to document J20AREOR850306 7

sh changes which may occur, but no further actions to address this occurrence are planned or necessary. 4.7 FISH Fish samples were collected semiannually and analyzed for gamma-emitting radionuclides. The gamma isotopic levels were below the LLDs, as has been the case in previous years. The data is presented in Table 7-1. 4.8 SPECIAL SAMPLES Twenty-four special samples were collected during the year and analyzed for gamma-emitting radionuclides. This includes six special samples from Outfall 007 that were also i analyzed for gross beta concentrations in addition to gamma-emitting radionuclides. Analysis results for special samples were below the LLDs for gamma-emitting radionuclides. However, Outfall 007 gross beta results ranged from 2.2 pCi/l to 4.8 pCi/1 with an average value of 3.4 pCi/1. These results are similar to the gross beta concentrations found in indicator location cistern water samples. This would be expected because one of the main components of Outfall 007 effluent is natural runoff. The data is presented in Table 7-1. Descriptions of the special samples collected are provided below: o Outfall 015 - Twelve samples of sewage plant effluent were analyzed from January through December 1985. o Outfall 007 - Six samples of Outfall 007 effluent were analyzed from June through November 1985. 4 J20AREOR850306 8

o Sediment - Five sediment samples were collected at the influent end of Sediment Basin B from August through December 1985. o Venison - A venison sample was collected November 25, 1985 at the Bucksnort Hunting Camp (Sector N, 1.8 miles). 4.9 LAND USE CENSUS The method used for conducting the 1985 Land Use Census was as follows: (1) Environmental Surveillance Program (ESP) personnel conducted field surveys in each meteorological sector out to five miles in order to locate the nearest resident, milk animal and garden. (2) Telephone confirmation was used in several instances when persodal contact could not be made. (3) As a result of these surveys, the following information was obtained/ confirmed in each meteorological sector: o nearest residence and owner's name & address o nearer unoccupied residence o nearest garden and approximate size o nearest milking animal (4) ESP personnel determined the locations of the nearest residence in each meteorological sector and the nearest garden in each meteorological sector and marke,d them on maps. Nearest residence is marked with an asterisk and nearest garden is marked with a square. These maps are included as Figures 4-1 and 4-2. (5) ESP personnel compared the 1985 Census results to 1984 Census results. The results of the 1985 Census are outlined below: o There were no milk animals located in any meteorological sector in the 5-mile zone surrounding the plant. , l , o The nearest residences in meteorological  ! sectors A, D, G and L has changed since the l 1984 Census. I l l J20AREOR850306 9

o The nearest garden in meteorological sectors F and R has changed since the 1984 Census. o There were no gardens located by the 1985 Census in meteorological sectors A, L, M, N, P and Q in the 5-mile zone. Although some minor changes occurred from 1984 to 1985, I there was no need to modify the Environmental Surveillance Program. Also, there was no location identified which yielded a calculated dose or dose commitment greater than those currently being calculated. However, administrative changes to the ODCM were necessary and these are reflected in the GGNS Offsite Dose Calculation Manual, Revision 7, Tables 2.2-3 and 2.3-1. The 1984/1985 Land Use Census changes are summarized in Table 4.2. The 1985 Land Use Census data sheets are presented in Table 4-3. In conclusion, the results of the 1985 Land Use Census indicated the land uses in the zero to 5-mile area surround-ing GGNS have remained basically the same as those reported in the 1984 Annual Land Use Census. 4.10 EXCEPTIONS TO THE ENVIRONMENTAL SURVEILLANCE PROGRAM 4.10.1 TLDs o Seven TLDs required by GGNS Technical Specifications were lost in the field during 1985. These losses were caused by vandalism and Mississippi River flood waters. TLD losses of this type are characteristic of other TLD programs and actions to prevent such losses have been ineffective. The 1985 TLD recovery rate was approximately 96% and is comparable with other TLD programs. J20AREOR850306 10

7.1 DATA FOR 1985 Table 7-1, 1985 Sampling and Analysis'Results, presents data obtained by Teledyne Isotopes on samples analyzed from i January 1 through December 31, 1985. The data was furnished by the analytical contractor, Teledyne Isotopes, as the January through December 1985 Monthly Progress Report. Table 7-2, AP&L Analysis Results, presents data obtained by the Arkansas Power & Light Environmental

  !          Laboratory for replicate vegetation samples collected on October 14, 1985.          The original October 14 samples were lost during shipment to Teledyne Isotopes.

Data presented in Tables 7-1 and 7-2 is reasonably ) comparable to that encountered in previous years and is indicative of what is expected in environmental media of this type. A few of the media, such as. sediment and Discharge Basin surface water, contained very slight amounts of radio-activity attributable to the operation of GGNS. However, no I release limit or reporting level was exceeded. l s 1 J i J20AREOR850306'- 7-1

1. 0 INTRODUCTION The following constitutes the current Monthly Progress Report for the Radio-logical Environmental Monitoring Program conducted at the Grand Gulf Nuclear Station, Port Gibson, Mississippi. Results of completed analyses are pre-sented in the attached tables. Missing entries indicate analyses that are not completed and the results will appear in subsequent reports.

Data obtained in the program are well within the ranges previously encountered in the program and to be expected in the environmental media sampled. None of the media sampled during 1985 contained radioactivity attributable to the operation of Grand Gulf Nuclear Station. For all gamma isotopic analyses, spectrum is computer scanned from 80 to 2048 Ke V. Specifically included are Mn-54, Co-58, Fe-59, Co-60, Zn-65, Zr-95, Nb-95, Ru-103, Ru-106, I-131, Ba-La-140, Cs-134, Cs-137, Ce-141, and Ce-144 Naturally occurring gama-emitters, such as K-40 and Ra daughters, are fre-quently detected but not listed here. Data listed as "<" are at the 4.66 sigma level, others are 2 sigma. Unless noted otherwise, the less than value ("<") reported under "Other Gammas" is for Co-60 and may be higher or lower for other radionuclides. All concentrations, except gross beta, are decay corrected to the time of collection. Deviations from Scheduled Sampling and Corrective Actions Taken All samples were collected within the scheduled period unless noted otherwise in the Listing of Missed Samples. i i

Appendix A Interlaboratory Comparison Program Results m. Y A-1

Appendix A Interlaboratory Comparison Program Results Teledyne Isotopes Midwest Laboratory (formerly Hazleton Environmental Sciences) has participated in interlaboratory comparison (crosscheck) programs since the formulation of its quality control program in December 1971. These programs are operated by agencies which supply environmental-type samples (e.g., milk or water) containing concentrations of radionuclides known to the issuing agency but not to participant laboratories. The purpose of such a program is to provide an independent cher on the laboratory's analytical procedures and to alert it to any possible prou 4 Participant laboratories measure the concentrations of specified radionuclides and report them to the issuing agency. Several months later, the agency reports the known values ta the participant laboratories and specifies control limits. Results consistently higher or lower than the known values or outside the control limits indicate a need to check the instruments or procedures used. The results in Table A-1 were obtained through participation in the environ-mental sample crosscheck program for milk, water, air filters, and food samples during the period 1982 through October 1985. This program has been conducted by the U. S. Environmental Protection Agency Intercomparison and Calibration Section, Quality Assurance Branch, Environmental Monitoring and Support Laboratory, Las Vegas, Nevada. The results in Table A-2 were obtained for thermoluminescent dosimeters (TLD's) during the period 1976, 1977, 1979, 1980, and 1981 through parti-cipation in the Second, Third, Fourth, and Fif th International Intercomparison of Environmental Dosimeters under the sponsorships listed in Table A-2. l A-2 l

i .- 4.0. Computation of Averages and Standard Deviations 4.1 Averages and . standard deviations listed in the tables are computed from all of the individual measurements over the period averaged; for example, an annual standard deviation would not be the average of quarterly standard deviations. The average I and standard deviations of a set of n numbers x1, x2, . . . xn are defined as follows: x=1n Ex s- r(x-x)2 n-1 4.2 Values below the highest lower limit of detection are not included  ; in the average. l 4.3 If all of the values in the averaging group are less than the highest LLD, the highest LLD is reported. 4.4 If all but one of the values are less than the highest LLD, the single value x and associated two sigma error is reported. t 4.5. In rounding off, the following rules are followed: (

                                                                                                                                                                                    +

As an example,11.443 is rounded off to 11.44. i l 4.5.2 If the figure following those to be retained is greater than , 5, the figure is dropped, and the last retained figure is  ! raised by 1. As an example,11.446 is rounded off to 11.45.. ' 4.5.3. If the figure following those to be retained is 5, and if there are no figures other than zeros beyond the five, the figure 5 is dropped, and the last-place figure retained is  ! increased by one if it is an odd nunber or it is kept unchanged if an e"en number. As an exaple,11.435 is  ; rounded off to 14.44, while 11.425 is rounded off to 11.42. i f B-3  ! i
