SUMMARY

l l This report samarizes the Shoreham Nuclear Power Station's (SNPS)

Radiological Environmental Monitoring Program (REMP) for 1987. SNPS received i a 5% power license in 1985. During 1987 the plant was shutdown except for a j period between May 26 and June 8, when testing below 5% power resmed.

The objective of the operational REMP is to identify and measure

' plant related radioactivity in the environment and calculate the potential dose to the surrounding pupulation. The operational phase uses the preopera-l

tional baseline data to identify plant contributed radiation and evaluates the possible effects of radioactive plant effluents on the environment.  !

The SNPS REMP is designed to comply with the Plant's Technical Specifications i and NRC Regulatory Guides.  !

i- The REMP data is acquired by sampling various media in the environment  !

which are then analyzed for any radiation present. Media sampled within the i aquatic environment included surf ace water, algae, fish, invertebrates '

(clams, lobsters, etc.) and sediment. The atmospheric environment was i sampled for airborne particulates, airborne iodine and noble gases. Milk, '

l potable water, precipitation, game and food p%1ucts were obtained from the i

terrestrial environment. Direct radiation W measured using thermo-lainescent dosimeters (TLDs).

Radioactivity in environmental media varies from sample to suple as well as geographically; therefore, a number of sampling locations for each -

media were selected using available meteorological, land and water use  !

. data. Sampling locations are designated as either indicator or control locations. The indicator locations are placed close enough to Shoreham so {

', that plant contributed radioactivity will be at its highest concentration. e

(

The control sample locations are placed so that they will be beyond measurable  ;

influence of Shoreham and any other nuclear facility. An exception to this i

. occurred at the on shore site for REMP location 13G2, at the entrance to i j Port Jefferson Harbor. During preoperational testing aquatic samples revealed the presence of low levels of iodine-131. An investigation revealed i t

that the iodine-131 was from area hospitals treating patients for thyroid L c arcinoma. Thereaf ter a second onshore aquatic background location was i sampled at the entrance to Mt. Sinai Harbor. T l A number of radioanalyses were performed on each medium s upled. All samples did not undergo all types of radioanalyses; only those analyses i appropriate for the particuler medi a were performed. The analyses included '

l gamma spectrometry, strontium-89 and -90, iodine-131, tritium, gross beta l radiation, direct radiation and noble gases. '

r i

l Dose calculations for the SNPS environs were perfonned using positive concentrations of radioactivity detected in the samples collected. In all cases the calculated doses were similar to the background doses calculated for the previous years. -

I. PROGRAM 9

3

THE PROGRAM The Shoreham Nuclear Power Station's (SNPS) Radiological Environmental  ;

Monitoring Program (REMP) is conducted in compliance with NRC regulations, licensing comitments, Program technical / legal requirements and the Plant's Technical Specifications. The REMP was developed in general accordance with the NRC Radiological Assessment Branch Technical Position (BTP) Rev.

1, Nov. 1979. LILCO's Updated Safety Analysis Repoit (USAR) 11.6, Environmental Report (ER) 6.1.5 and Technical Specification Section 3/4.12.

All samples were collected by personnel of the Long Island Lighting Company (Environmental Engineering Department) or EA Engineering, Science and Technology Inc. A synopsis of the sampling program can be found in Table 1.

A map and description of sampling locations appear in Appendix B. More detailed information concerning sample locations and collection is available in niMP Procedure 1.0 Radiological Environmental Monitoring Prograt '.REMP)

Program Oescription.

During 1987 sample analyses were performed by Teledyne isotopes (TI) of Westwood, New Jersey (referred to througho'Jt the text as "the laboratory"),

under contract to LILCO. A sunmary of analytical results appears in Appendix A and individual analysis results in Appendix C.

A. Objectives The objectives of the operational radiological environmental monitoring program are:

1. Identify and measure plant related radioactivity in the environment for the calculation of the potential dose to the population.

2. Identify excessive radionuclide concentration of limited duration so that appropriate action may be taken.

3. Determine the long term variation in radionuclide concentrations.

4 Determine the effects of plant effluent on the envirorynent.

i

5. Comply with regulatory requirements and specifications and provide j records to document compliance.

6. Sample Collection

1. Aquatic Environment The aquatic environment at the SNPS site was examined by analyzing samples of surface water, fish, invertebrates, aquatic plants and sediment. Surface water samples were taken at six loca-tions in May and October using a Niskin bottle or by wading into the -

water and filling a new two gallon polyethylene bottle. The samples were placed in new polyethylene bottles following three rinses with the suple medium prior to collection. Samples of Winter Flounder, Pseudopleuronectes americanus, Windowpane, Scophthalmus aquosus, Sea Robin, Prionotus spp, Little Skate, Raja erinacea, and Summer Flounder (Fluke), Paralichthys dentatus were taken by trawl, sealed in plastic bags, frozen, and shipped to the laboratory for analysis, r Invertebrate samples of Merican Lobster, Homarus americanus, Squid, Loligo pealeil and Channeled Whelk, Busycon canaliculata were collectec by trawl. Channeled Whelk were also collected using pots.

These invertebrate samples were sealed in plastic bags, frozen and shipped to the laborato g for analysis. Blue Mussels, Mytilus edulis were collected by hand along jetties. Soft-shell clams, Mya arenaria, and Oysters, Crassostrea virginica, from Wading River were shelled and sealed in plastic bags, frozen ano shipped to the laboratory.

Aquatic plants, Fucus sp., Ulva lactuca, Enteromorpha sp., and Codium sp., among others were collected while trawling for the fish samples and from along the shoreline, then sealed in plastic bags, refrigerated and snipped. Deep water sediment was collected using a Smith-MacIntyre bottom sampler, sealed in plastic bags, frozen and shipped. Beach sediment samples were also collected, sealed in plastic bags, frozen and shipped to the laboratory.

2. Atmospheric Environment

! The atmospheric environment was examined by analyzing airborne 1

particulates collected on Gelman Type A/E filters using low volume air samplers (approximately 1 cfm). Airborne iodine was collected by absorption on triethylenediamine (TEDA) impregnated charcoal car-tridges which were connected in series behind the airborne partic-ulate filters. The samplers used were equipped with a vacuum recorder for sample volume correction and to ensure sample validity and indicate maintenance problems when they occurred. Should the sampler lose vacuin due to a leak tne vacuum level reading will drop I to zero. Since this may occur without a corresponding loss of electric supply the exact time of the maintenance problem will be evident on the recorder chart.

Sample volumes were measured using dry gas meters and corrected for differences between the actual pressure seen by the volume meter and the average atmospheric pressure. Sample volumes are l corrected to standard pressure using average weekly barometric 1

5

A pressure (measured at Environmental Engineering Department, Melville) and air sampler vacuum readings. Time totalizers indicate the duration of time the s uple was taken.

Air samples were collected weekly at St. Joseph's Villa and analyzed for the Noble Gases Krypton-85 and Xenon-133. The samples were collected using a modified low pressure air compressor. Outside air is drawn into an interim holding tank evacuated to 20" Hg and then transferred to a nmple tank for transport to the laboratory for analysis.

3. Terrestrial Environment The terrestrial environment was examined by analyzing samples f of milk, precipitation, potable water, game, food products, and soil.

When available, milk samples were collected from four locations monthly, except during the pasture season (May through October) when the sampling was increased to twice a month. Milk samples were shipped on ice with Sodium Bisulfite (NaHS03) preservative added.

Precipitation was collected at two locations weekly. In order to ensure sufficient sample volume weekly precipitation samples were combined for a monthly sample composite. Potable water was collected quarterly from'three well locations. Game samples (Squirrel, Sciurus carolinensis and Raccoon, Procyon lotor) were obtaintd semi-annually from on site locations, sealed in plastic bags, frozen and then shipped. Food products consisting of vegetables and fruit were collected from area f arm stands and shipped fresh to the laboratory.

4 Direct Radiation Direct radiation levels in the environs were measured with energy compensated Calcitn Sulfate (CaSO4:Dy) TLDs, each contain-ing four separate readout areas. The TLDs are annealed by LILC0 prior to placement in the field. Two TLDs were placed at 36 locations and exchanged on a monthly and quarterly cycle, respectively. The units were then packaged and shipped to the laboratory for analysis.

C. Quality Assurance

1. Teledyne isotopats l i I

Teledyne isotopes (TI) has an extensive quality assurance progra designed to ensure the precision and accuracy of the data generated. An Interlaboratory Comparison Progra is conducted with

( the Environmental Protection Agency (EPA). The results of the Progra analyses are listed in Appendix E. Participation in this l

program permits estimation of bias in Tl results from the deviation [

6

e from the "known" value given, or by comparison with means of all participants. The Tl Quality Assurance Program for Radiological i Monitoring is described in various TI publications (references 15, '

16,17).

Approximately 10 percent of TI's total analytical effort is spent on quality control including process quality control, instrument quality control, intra and interlaboratory cross-check, and compre-hensive data review. In addition, LILC0 specifically requires that ten percent of its analyses be duplicated for further quality control cross check.

2. Long Island Lighting Company

a. Nuclear Review Board (NRB) Audit The annual REMP NRB audit was conducted on May 4 8, 1987 As with last year's audit the 1987 NRB audit focused on internal LILC0 ,

REMP activities in the Environmental and Nuclear Engineering, Nuclear ,

Operations Support and Shoreham Operations Departments. The Program areas audited were: procedures, records control, sample collection and documentation, training records, analysis results, land use surveys and interlaboratory comparison progrvns.

Audit report NK 87-01 was issued on June 10 listing one (1) finding and five (5) observations. No SNP5 Technical Specifications Violations were cited. Corrective action on the one finr'ing was completed by April 1, 1988.

b. LILCO Quality Assurance Audits  ;

1. Field Audit  !

/ The REMP sampling effort has been audited by LILCO's QA Department since the beginning of the Program. The 1987 surveillances were conducted on March 12 (Milk), May 27 (Fish and Invertebrates) and July 14 (Noble Gas and Precipitation).

No findings were noted during these surveillances.

2. Environmtental Radiological Laboratory Audit As with the REMP field sampling the environmental radiological laboratory performing REMP radioanaly,ses has been audited annually since the start of monitoring. Tne laboratory utilized during 1987 was Teledyne Isotopes.

This years' surveillance was performed on December 10, 1987, at Teledyne's laboratory in Westwood, New Jersey. This surveillance sought to verify corrective actions taken in response to the 1986 audit. All findings from the 1986 audit have been addressed by Teledyne and are closed.

D. Data Interpretation

1. General The analytical data generated during the program are routinely evaluated by the TI project leader who is the liason with Long Island Lighting Company's Environmental and Nuclear Engineering Departments.

Several factors are important in the interpretation of the data.

These f actors are discussed here to avoid repetition in sections that follow.

Within the data tables (Appendix C) an approximate 95 percent (12 sigma) confidence interval is supplied for those data points above the lower limit of detection (LLD). These intervals represent the range of values into which 95 percent of repeated analyses of the same sample would f all. Tables C-19 and C-20 present typical and required LLD's, respectively.

Results for each type of sample were grouped according to the analysis performed. Means and standard deviations of these results

. arte calculated when applicable. The calculated standard deviations of grouped data represent sample rather than analytical variability.

For these calculations any values below LLO are considered to be at the LLD. As a result, the means are biased high and the standard deviations are biased low. When a group of data is composed of mainly LLD values (>50%), averages are not calculated.

1 i 8

e Grab sampling is a useful and acceptable procedure for taking environmental samples of a mediun in which the concentration of radionuclides is expected to vary minimally with time or where inter-mittent sampling is deemed sufficient to establish the radiological characteristics of the medium. This method, however, is only repre-sentative of the supled medium for that specific location and instant of time. As a result, variation of radionuclide concentra-tions in the s uples will normally occur. Since these variations will tend to counterbalance one another, the extraction of averages based upori repetitive grab samples is valid.

2. Gamma Isotopic Analyses SNPS Technical Specifications Table 3.12.1-1 requires that ana'yses be performed on all media for gamma emitting radionuclides which may be attributable to effluents from the plant. These analyses are in addition to requirements for specific game emitters such as I-131, Cs-134, Cs-137 Ba-140, Mn-54, Fe-59 Co-58, Co-60, Zn-65, Zr-95 and Nb-95. Industry experience suggests that these are the most likely radionuclides to find their way into the environment from a BWR nuclear power plant. Gamma spectroscopy is expected to identify most other nuclides which may be discharged when the LLD's for specified gama emitters are met by this technique.

Tables 3.1 and 3.2 of the Shoreham Final Environmental Statement list tne calculated liquid and gaseous effluents by radionuclide in curies per year. These release rates assume normal operation of the plant, including anticipated operational occurrences. Those nuclides listed in Tables 3.1 and 3.2 which are not routinely observable by

• gbnma spectroscopy and which are not specifically analyzed in other ways fall into two categories:

1. Those radionuclides with half-lives on the order of hours or minutes which cannot accumulate appreciably in the environment (Na-24 Cu-64, Zn-69m 2n-69, Sr-91, Y-91m. Y-92, Y-93, Tc-99m, Rh-10 h , Rh-105, Rh-106, Te-129. Te-131m. Te-131, 1-132, 1-135 Ba-137m Pr-143, Ce-143, Pr-144 and W-187).

2. Those radionuclides with no gamas (P-32, Fe-55), those with a trivial percentage of their transitions going by gamma emission (Y-91), or those with their primary gama occurring at such a low energy and at such low abundance that it is not routinely observable in the presence of other gama activity (Nd-147). With only 10 pCi of hd-147 calculated to be released per year in Shoreham's liquid effluents, the nuclide cannot be an important contributor to dose.

9

E. Dose Assessment .

In order to assess the total dose an individual may receive from the Shorehm environment, appropriate environmental suples, located along critical effluent pathways, are analyzed for the presence and total activity of specific radionuclides. The exposure an individual receives may then be approximated by quantitative analysis of these radionuclide concentrations in air, water, milk and food samples as well as due to direct radiation exposure. It is also possible to estimate the dose rate to a particular internal body organ when the average concentrations in a particular environmental medium are known, Radionuclides may enter the body through ingestion of water and milk, inhalation of and imersion in air, submersion in water, or consmption of food. Thas, in order for the REMP to provide an estimate of the total radiation dose, a radionuclide intake is deterTnined for each pathway.

The methodology for determining doses is similar for all path-ways. Laboratory analyses from the REMP for each sample type are compiled. Data from all locations taken on the same date are averaged to obtain the most reliable approximation of the radioactivity concen-tration on that date for that sample type. The averages of all dates are then taken to provide the best approximation of radioactivity concentrations for the year.

When an average value has been obtained which represents a sample medium or an exposure pathway, it can then be used to calculate the i dose for the year. Additional information, such as the quantity of fish, milk, water, meat, vegetables, etc., consumed per year by the maximum individual is also needed to calculate the total dose (13).

'The dose due to direct radiation exposure is monitored by TL0s.

Tne laboratory results for TLD's are expressed in dose units directly and do not require any additional calculations.

The dose to the total body or to a specific organ is then calcu-lated by the product of the radionuclide specific dose conversion f actor for its applicable exposure pathway, the environmental sample

! radionuclide concentration, and the ingestion or inhalation rate of the sample or medium of interest. For example, the following general equation expresses this principle:

Dose = Concentration x Quantity ingested x Dose factor (mrem /yr) per sample per year i

l The sample concentration is typicaly expressed in pCi/l or pCi/kg.

For the ingestion pathway, the quantity ingested or constJned per year is expressed in kg/ year or 1/ year. Finally, the dose conversion factor is expressed in terms of mrem /pCi ingested or innaled.

RESULTS AND O!SCUSSION The analytical results for the reporting period of January 1 through December 31, 1987, have been divided into four categories: aquatic, atmospheric, terrestrial, and direct radiation. The individual senples and analyses within each category display the unique radiological characteristics of that type of environment. Analytical results of the REMP are stsnmarized in Appendix A. The data for individual analyses are presented in Appendix C.

A. Acuatic Environment The aquatic environment in the vicinity of SNPS' consists primarily of Long Island Sound. The radiological characteristics were studied by i analyzing samples of surf ace water, Winter Flounder, Windowpane, Sea Robin,

Little Skate, Summer Flounder, American Lobster, Squid, Channeled Whelk, Blue Mussels, Sof t Shell Clams, aquatic plants and sediment. The samples were collected by LILCO Environmental Engineering Department and EA Engineering Science and Technology Inc. (under contract ,to LILCO). '

1. Surf ace Water (Table C-1)

Semiannual surf a'.t water samples were taken at six locations and I were analyzed for tritium, gama emitters, iodine-131, and strontium-89 -

and strontium-90.

Five surf ace water samples analyzed for tritium showed detectable levels between 170 and 430 pCi/l with an average of 268 pCi/t. The other seven samples were btalow the lower limit of detection. This is consistent with tritium concentrations observed in surface water during 1983 and 1984, 1 the preoperational period, and in 1985 and 1986. ,

! Naturally occurring potassium-40 was measured in eleven of the 1 samples with an average of 309 pC1/f and a range between 54.7 and 1290  :

Gi/1. No other gamma activity above the detectable levels was measured in ,

the twelve surf ace water samples as analyzed by gamma spectroscopy.

Surf ace water samples were also analyzed for iodine-131, strontium-89, and strontium-90. hone of these nuclides were observed within the limits ,

of detection, i

2. Fish (Table C-2) -

i l j Twenty-six fish samples were collected at three locations and the edible portions analyzed for ganrna emitters. Gamma spectrometry showed

! potassium-40 present in all samples with an average concentration of 3456 j pCi/kg wet and a range between 2040 and 4480 pCi/kg wet. Cesium-137 .

i wat detected in seven samples with an average activity of 14.6 pC1/kg wet i and a range between 8.9 and 25.8 pCi/kg wet. These activities are less than those reported in 1983 and 1984 during the preoperational period, and 1 Comperable to those reported in 1985 and 1986. i

3. Invertebrates (Table C-3) ,

Twenty-three invertebrate samples, comprised of sof t shell clams, oysters, mussels, lobsters, squid, and whelks, were collected at six locations and analyzed for gama emitters, strontim-89 and strontim-90.

Gamma spectrometry showed detectable levels of potassim-40 in all samples, ranging from 1090 to 3870 pC1/kg wet with an average activity of 2391 pCi/kg wet. Naturally occurring beryllim-7 and thorium-228 were each measured one time with acttvities of 73.9 and 101 pCi/kg (wet), respec-tively. Cesium-137, attributed to f allout, was measured in two suples with activities of 34.8 and 36.2 pCi/kg wet. Neither strontium-89 or strontim-90 was detected.

4 Aquatic Plants (Table C-4)

Marine algae, collected at five locations (ten suples) in Long Island Sound and at one location in Wading River Marsh (two suples), were analyzed for gamma emitters and strontium-89 and strontium-90. Gamma spectrometry showed detectable potassium-40 in all samples ranging from 2930 to 36900 pC1/kg dry with an average of 17527 pCi/kg dry. Cosagenically ,

produced beryllium-7 was measured in eight of the s uples ranging from 172 to 3760 pCi/kg dry with an average activity of 1159 pCi/kg dry. Cesim-137 was measured in one sample with an activity of 85.5 pCi/kg dry. Naturally '

occurring thori m-228 was measured in nine samples with an average activity of 361 pCi/kg dry and a range of 111 to 1190 pCi/kg dry. Radium-226 was measured in two s uples with an average activity of 1086 pCi/kg dry and a range of 711 to 1460 pCi/kg dry. Strontim-90 was measured in two samplas with an average activity of 13.2 pCi/kg dry and a range from 8.3 to 18 pCi/kg dry. Strontim-89 was not observed.

The measured activities for Strontium-90 and Cesium-137 are consistent with those reported during the preoperational period of 1983-1984.

5. Sediment (TableC-5)

Eight of fshore sediment samples were collected in May and November at four offshore locations and analyzed for gama emitters and strontium-89 and l strontium-90. For the summation.of samples collected, location 4A3 is grouped with the offshore sites. Gama spectrometry showed detectable levels of potassim-40 in all samples ranging from 1840 to 8310 pCi/kg dry with an average activity of 3996 pCi/kg dry. Naturally occurring radi m-226 was observed in one sample with an activity of 839 pCi/kg dry. Thorium-228, also naturally occurring, was measured in seven samples within the range of 123 to 1080 pCi/kg dry with an average activity of 463 pCi/kg dry.

Cesium-137 was measured in one suple with an activity of 2167 pCi/kg dry.

All other gama emitters, were below the lower. limit of detection. No l strontin-89 or strontim-90 was detected in these samples.

Twelve beach sediment suples were collected and analyzed for strontium-89, strontium-90 and gama enitters. No stronti m was detected.

All suples had measurable activities of naturally occurring potassium-40 with an average activity of 2999 pC1/kg dry and a range of 1490 to 4900 pCi/kg dry. Two smples had measurable radium-226 with an average activity L

M1 , _ _ _ _ _ . _ _ _ _ _ _ _ _ __

of 859 pCi/kg dry and a range of 478 to 1240 pCi/kg dry. Eleven suples had i measurable thorium-228 with an average activity of 198 pCi/kg dry and a range of 74.0 to 741 pCi/kg dry. All other game emitters were below the lower limit of detection.

1 B. Atmospheric invironment The atmospheric environment in the vicinity of the SNPS was examined by analyzing smples of airborne particulates and airborne todine at 16 s upling locations. TEDA-impregnated charcoal cartridges used to collect airborne iodine were collected weekly and analyzed by gama spectrometry for ,

iodine-131. Airborne particulate filters were collected weekly and analyzed for beta emitters. Quarterly composites from each station were analyzed for gama emitters and radiostrontium.

1. Airborne Particulates (Tables C-6, C-7, C 8 and C-9)

Beta-emitter concentrations ranged *from 0.004 to 0.032 pC1/m3 with an annual average for the 16 supling locations of 0.016 pCi/m3 -

(Table C-6). Of the 796 measurements nine were below the detection limit, nominally 0.004 pCi/m3 Figure 1 shows the average weekly gross beta fluctuations in air particulates from all stations for 1987.

Figure 2 represents the avera particulates from January 1, 1977 ge monthly through gross beta Dec eber 31,results 1987. in air Results of gama spectrometry (Table C-7) showed detectable levels of naturally occurring bery111um-7 in all sixty two suples. Due to an i electric cable f ailure no weekly suples were collected at station 652 in the third and fourth quarters. Therefore, there ore only 62 composite ,

suples for the year. The average bery111um-7 activity in the q analyses was 0.084 pCi/mJ with a range of 0.046 to 0.128 pCi/m3.uarterly Naturally occurring potassium-40 was obserted seven times. The potassium-40 had an average of 0.015 pCi/m3 with a range of 0.0089 to 0.028'pCi/m3 All other gamma emitters were below the lower limit of 1 detection.

The radiostrontin analyses on the 62 quarterly composites showed i no detectable levels of strontium-89 or stronti m-90. '

2. Airborne lodine (Table C-9)

Analytical results of airborne iodine-131 were all belgw the lower t limit of detection which ranged between 0.01 and 0.06 pCi/m3 [,

3. Noble Gas (Table C-18)

Air suples were collected weekly at St. Joseph's Villa and ,

! analyzed for Krypton 85 and Xenon-133. Xenon-133 was not found in any sample. All 52 s uples had p ranging from 24 to 45 pC1/m3,ositive concentrations with an average of Krypton-85 concentration of 32

pCi/m3, similar to the average concentrations found during the pre- i operational years.  !

C. Terrestrial Environment The terrestrial environment in the vicinity of the SNPS was examined by analyzing samples of game (raccoon and squirrel), milk, food products, rainwater and potable water. Gama spectrometry was performed on all s amples , in addition, iodine-131, stronti m-89 and strontium-90 analyses were performed on the milk samples, while tritium and iodine-131 analyses were performed on the potable water samples. Rainwater samples were analyzed for gross beta, tritium and gamma emitters.

1. Milk (Tables C-11 and C-12)

All of the 60 monthly and semimonthly cow and goat milk samples analyzed for iodine were below the LLD which ranged between <0.2 and <0.6 pCi/t. Naturally occurring potassium-40 was oM erved in all the milk samples. The goat milk samples had an average mesurement of 1332 pCi/l and a range of 1190 to 1860 pCi/l. The cow milk samples had an average concen-tration of 1270 pCi/l with a range of 800 to 1880 pCi/l. Cesium-137 was detected in seven of the 31 goat milk samples with in average of 8.7 pCi/l and a range of 7.5 to 10.1 pCi/l. Six of the 27 cow milk sanples had detectable measurements of cesim-137 with an average of 8.4 pCi/l and a range of 5.9 to 11.5 pCi/1.

All other gamma emitters, as well as strontium-89 were below the detection limit. Strontium-90 was observed in all of the cow and goat milk samples. In the 18 cow milk samples, the average strontium-90 concentration was 5.8 with a range from 1.3 to 15.0 pCi/f. For the 22 goat milk samples, the average strontim-90 concentration was 2.4 pCi/f and the range was from 0.61 to 6.3 pC1/l. The activities reported for strontium-90 are consistent with those found in cow and goat milk samples from 1983 to present.

2. Potable Water (Table C-13)

Tritium activity was measured in four of the twelve potabl? water samples collected at three locations. In these four samples, t?' average tritium concentration was 253 pCi/l with a range of 140 to 450 pCi/1. The other tritium results were below the lower limit of detection which varied between 100 and 200 pCi/l. This is consistent with the iesults of the

previous four years. No iodine-131 was measured above the lower limit of detection which was between 0.2 and 0.3 pCi/f. Naturally occurring potassium-40 was observed in one sample with an activity of 60.5 pCi/l. All other gamma emitters were below the lower limit of detection.

l

3. Game (Table C-14)

Potassium-40 was observed in the four game samples (two raccoons and two squirrels) with an average activity of 3173 pCf /kg wet and a range from 2370 to 3960 pCi/kg wet. However, cesium-137, the only other observed gamma emitter, was measured over a greater range of activity due presumably to differences in diets and possibly to seasonal effects. For the two raccoon samples the average cesium-137 activity was 277 pCi/kg wet and the two tralues were 35.1 pCi/kg wet and 518 pCi/kg wet. These results are consistent with results of the previous four year;. The average cesium-137 activity in the two squirrel samples was 3321 pCi/kg wet and the range was from 152 to 6490 pCi/kg wet.

4. Food Droducts (Table C-15)

Sixty-six human food products from local f arms were analyzed, including tomatoes, potatoes, cabbage, lettuce, beets, radishes, spinach, onions, ,

collards, strawberries, carrots, and corn. All samples contained naturally '

occurring potassi m-40 with an average of 2951 pCi/kg wet and a range of 1250 to 7200 pCi/kg wet. Naturally occurring beryllium-7 was measured in i seven samples with an average activity of 171 pCi/kg wet and a range of 91.8 to 250 pCi/kg wet. The seven samples were lettuce and spinach, both being large surf ace leafy vegetables onto which beryllim-7 could deposit from the atmosphere. Cesium-137 with an activity of 86.3 pCi/kg wet was measured in one lettuce sample. Naturally occurring thorim-228 was detected with an activity of 67.9 pCi/kg wet in one spinach sample. All other gamma emitters were below the lower limit of detection. The samples were also analyzed for iodine-131 by a radiochemical procedure. No activity was found. The detection limit varied from 3 to 30 pCi/kg wet.

5. Precipitation (Table C-10)

Twenty-four precipitation samples were collected at two stations during the twelve months and analyzed for gross beta, tritium and gamma emitters.

Gross beta activity was measured in the 24 samples with an average activity of 8.2 and a range of 1.8 to 65 pCi/1.

Tritium was measured in nine of the 24 samples with an average activity of 252 pCi/l and a range of 130 to 370 pCi/1.

Naturally occurring beryllim was observed in five samples from station 12A1 with an average of 72.1 pCi/t and a range of 48.7 to 85.1 pCi/1. All other gamma emitters were below detection limits. .

D. Direct Radiation (Tables C-17 and C-18)

Direct radiation measurements were taken monthly and quarterly at 36 l locations using CaSO4:Dy thermoluminescent dosimeters (T'.Ds). TLDs were

( used to detect radiation levels near ground level in the vicinity of the Shoreham site due to terrestrial and cosmic gama ray emitters and possible SNPS contributed direct radiation. Figure 3 presents a compar ison of average TLD results from 1977 to 1987. All TLD results presented in this report have been normalized to a standard month (30.4 days) to eliminate the apparent differences caused by the variations in exposure period. The average cf the quarterly exposures was 3.7 mR/ standard month and the average of the c.enthly exposures was also 3.7 mR/ standard month. This is less than quarterly and monthly values, respectively, measured during the pre-operational years 1983 and 1984.

E. Dose Assessment Table 2 summarizes the results of the dose assessment determinations based on 1987 data.

Initially all positive concentrations of radionuclides in indicator samples, as shown in Appendix A, were considered for inclusion in the dose calculation. In an attempt to factor out as much of the contribution due to natural and man-made background radiation as possible, indicator and control sample results were compared. If the control location results were com-parable to or greater than those at the indicator location, then the indicator sunple results were not included in the dose assessment. Surface water, aquatic plants and precipitation were not considered as significant human exposure pathways and, therefore, not considered in the dose assessment.

The dose due to standing on contaminated soil / sediment was not calculated since this is accounted for in the direct radiation dose.

Bery111un-7, potassium-40, radium-226, radium-228 and thorium-228 are all naturally occurring isotopes and not likely to be produced as a result of the operation of Shoreham so they were excluded. Krypton-85 was also excluded as an individual contributor to dose since it is not absorbed or -

ingested and is included in the direct radiation component. The remaining .

positive isotopes, cesium-137, strontium-90 and tritium, could be produced as a result of plant operation so they were included in the dose calculations.

It should be noted that tritium also occurs naturally as a result of cosmic interactions, and cesium-137 and strontium-90 exist in the environment as a result of atmospheric weapons testing and the Chernobyl accident.

Comparison of the results of the dose assessment of 1987 with those of the preoperational years 1983 and 1984, show similar results for all three years. The direct radiation dose in 1987 (Appendix 0) was less than in 1983 and 1984. Doses calculated for 1983 were based on ingestion factors

. f or the averaos individual, whereas the maximun individual ingestion factors were used in 1984 and 1987. This makes exact comparison of the results difficult; however..the dose is directly proportional to the activity in the medium: in all cases considered the concentrations found in 1987 are consistent with those of 1983.

It should be noted that cesium-137 found in game samples was considered as a dose contributor by using ingestion factors for meat. This is highly conservative.

CONCLUSIONS During 1987 the Shoreham Nuclear Power Station conducted tests at power levels below 5% between May 26 and June 8, and was shutdown for the remainder of the year.

The accident at the Chernobyl nuclear reactor in 1986 in Russia contributed measurable amounts of radioactivity to the environment still evidenced in 1987. By comparison of results for indicator and control locations, most of the positive results for possible plant generated radionuclides can be attributed to natural or man-made background radiation and not Shoreham. Otherwise, analyses of the environmental samples show results consistent with those found during the preoperational years 1983 and 1984. Sensitive indicators revealed minute quantities of radioacthe fallout from the October 1980 atmospheric nuclear weapons test by the Peoples Rebuplic of China, in addition to radioactivity remaining from two decades of atmospheric testing.

Along with these anomalies in the environment, expected normal back-ground radioactivity has been measured in REMP samples. Aquatic and terrestrial samples were analyzed and reflected the normal background radiation found in the environment. The atmospheric environment was sampled for airborne particulate matter, iodine, and noble gases. Figure 1 represents the average weekly gross beta results in airborne particulates from January through December 1987. Figure 2 shows the average monthly gross beta results in airborne particulates from February 1977 to December 1987. Direct radiation levels were relatively low and approximately the same at all locations. Figure 3 shows the average quarterly TLD results in mR/ standard month from January 1977 to December 1987.

41 .

j APPENDIX B i

l Sample Designation LILC0's Radiological Environmental Monitoring Program (REMP) identifies samples by a three , irt code. The first two letters are the power station identification code, ;n this case "SN". The next three letters are for the media sampled.

SWA = Surf ace Water (Long Island Sound) GMK = Goat Milk AQF = Fish (1) PWA = PotableWater(groundwater)

=

AQI = Invertebrates (1) GAX Game (1)

AQP = Aquatic Plants (1) FPV = Food Products (1)

AQS = Sediment FPF = Fruit

=

APT = Airborne Particulates IDM Immersion Dose (TLD)

AIO = Airborne lodine NBG = Noble Gas MLK = Milk RWA = Precipitation (Rain Water)

SOL = Soil The last four synbols 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 1/2 degrees centered about the reactor site. Sector one is divided evenly by the north axis, and other sectors are numbered in a clock-wise 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 0 = 3-4 miles off site The last number is the location numerical designation within each sector and zone, e.g.,1,2,3,....For example, the designation SN-SWA-3C1 would indicate a sample in the SNPS program SN, consisting of surface water SWA, which had been collected in the 22-1/2 degree sector centered on the northeast axis (3) between the site boundary and 2-3 miles off site (C). The number 1 indicates that this is sampling station No.1 in the designated area.

Sampling Locations All sampling locations and specific information about the individual locations are given in Table B-1. Tables B-2 through B-5 list the sampling locations and media required by Technical Specifications.

l l

(1) A more specific means of classification will be noted inFor theexample, comment AQI section of each laboratory report for these samples.

l will be designated, n. the sample description, as aquatic invertebrate.

(

However, the coment section will specify the sample type by the generally accepted comon name of the sample involved. In this case, clam, lobster, crab or other aquatic invertebrate would be listed in the coment section.

APPENDIX B Sampling Locatior.s Maps B-1, B-2 and B-3 show the locations of 1987 sampling stations with respect to the site. These maps are tracings of portions of larger maps prepared by LILCO's Survey Division after an extensive land survey of REMP monitoring locations. Additional information can be obtained by referring to the Site and Vicinity Map of the Shoreham Nuclear Power Station (Map B-2), the map of Long Island and Connecticut Shore (Map B-3) and by.

i DETERMINATION OF GROSS BETA ACTIVITY IN WATER SAMPLES

1.0 INTRODUCTION

The procedures described in this section are used to measure the

~

overall radioactivity of water samples without identifying the radioactive species present. No chemical separation techniques are involved.

One liter of the sample is evaporated on a hot plate. A smaller volume may be used if the sample has a significant salt content as measured by a conductivity meter. If requested by the customer, the sample is filtered through No. 54 filter paper before evaporation, removing particles greater than 30 microns in size.

After evaporating to a small volume in a beaker, the sample is rinsed into a 2-inch diameter stainless steel planchet which is stamped with a concentric ring pattern to distribute residue evenly. Final evaporation to dryness takes place under heat lamps.

Residue mass is determined by weighing the planchet before and after mounting the sample. The planchet is counted for beta activity on an automatic proportional counter. Results are calculated using empirical self-absorption curves which allow for the change in effective counting efficiency caused by the residue mass.

t 93

v .

2.0 DETECTION CAPABILITY Detection capability depends upon the sample volume actually represented on the planchet, the background and the efficiency of the counting instrument, and upon self-absorption of beta particles by the mounted sample. Because the radioactive species are not identified, no decay corrections are made and the reported activity refers to the counting time.

The minimum detectable level (MDL) for water samples is nominally 1.6 picocuries per liter for gross beta at the 4.66 sigma level (1.0 pCi/l at the 2.83 sigma level), asstning that i liter of sample is used and that 1/2 gram of sample residue is mounted on the planchet. These figures are based upon a counting time of 50 minutes and upon representative values of counting efficiency and background of 0.2 and 1.2 cpm, respectively. These figures are based upon a 200 minute counting time and upon a representative efficiency of 0.02 and a background of 0.1 cpm.

The MDL becomes significantly lower as the mount weight decreases because of reduced self-absorption. At a zero mount weight, the 4.66 sigma MOL for gross beta is 0.9 picoeuries per liter. These values reflect a beta counting efficiency of 0.38 and an alpha counting efficiency of 0.18.

ANALYSIS OF SAMPLES FOR TRITIUM Water Approximately 2 ml of water are converted to hydrogen by passing the t:ater, heated to its vapor state, over a granular zine conversion column heated to 400* C. The. hydrogen is loaded into a one liter proportional detector and the vol me is determined by recording the pressure.

The proportional detector is passively shielded by lead and steel and an electronic, anticoincidence system provides additional shielding from cosmic rays.

l Stable strontiun carrier is added to 1 liter of sample and the volume is reduced by evaporation. Strontium is precipitated as Sr(NO3 )2 using nitric acid. A barium scavenge and an iron (ferric hydroxide) scavenge are performed followed by addition of stable yttrium carrier and a 5 to 7 day period for yttrium ingrowth. Yttriun is then precipitated as hydroxide, is dissolved and re-precipitated as oxalate. The yttriun oxalate is mounted on a nylon planchet and is counted in a low level beta counter to infer Sr-90 activity. Strontium-89 activity is determined by precipitating SrC03 from the sample af ter yttriun separation. This precipitate is mounted on a nylon planchet and is covered with an 80 mg/cm2 aluminum absorber for low level beta counting.

GAMMA SPECTROMETRY OF SAMPLES Milk and Water A 1.0 liter Marinelli beaker is filled with a representative aliquot of the sample. The seple is then counted for approximately 1000 minutes with a shielded Ge(Li) detector coupled to a mini-computer-based data acquisition system which performs pulse height analysis.

Dried Solids Other Than Soils and Sediments A large quantity of the sample is dried at a low temperature, less than 100*C. As much as possible (up to the total sample) is loaded into a tared 1-liter Marinelli and weighed. The sample is then counted for approximately 1000 minutes with a shielded Ge(Li) detector coupled to a mini-computer-based data acquisition system which performs pulse height analysis.

Fish As much as possible (up to the total sample) of the edible portion of the sample is loaded into a tared Marinelli and weighed. The sample is then counted for approximately 1000 minutes with a shielded Ge(Li) detector coupled to a mini-computer-based data acquisition system which performs pulse height analysis.

Soils cnd Sediments Soils and sediments are dried at a low temperature, less than 100*C.

The soil or sediment is loaded fully into a tared, standard 3')0 cc container and weighed. The sample is then counted for approximately six hours with a

' shielded Ge(Li) detector coupled to a mini-computer-based data acquisition system which performs pulse height analysis, Charcoal Cartridges ( Air Iodine)

Charcoal cartridges are counted up to five at a time, with one positioned on the face of a Ge(Li) detector and up to four on the side of the Ge(Li) detector. Each Ge(Li) detector is calibrated for both positions.

The detection limit for I-131 of each charcoal cartridge can be determined (assuming no positive 1-131) uniquely from the volume of air which passed through it. In the event 1-131 is observed in the initial counting of a set, each charcoal cartridge is then counted separately, positioned on the face of the detector.

Air Particulate The thirteen airborne particulate filters for a quarterly composite for each field station are aligned one in front of another and then counted for at least six hours with a shielded Ge(Li) detector coupled to a mini-computer-based data acquisition system which performs pulse height analysis.

ENVIRONMENTAL 00SIMETRY Teledyne Isotopes uses a CaSO4 :Dy thertnoluminescent dosimeter (TLD) which the company manufactures. This material has a high light output, negligible thermally induced signal loss (f ading), and negligible self dosing. The energy response curve (as well as all other features) satisfies NRC Reg. Guide 4.13. Transit doses are accounted for by use of separate '

TLDs.

Following the field exposure period the TLDs are placed in a Teledyne '

Isotopes Model 8300. One fourth of the rectan and the measured light emission (luminescence) gular TLDThe is recorded. is heated at a time TLD is then annealed and exposed to a knowr, Cs-137 doss; each area is then read again.

This provides a calibration ut each area of each TLD after every field use.

Notes:

(a) EPA Results-Expected laboratory precision (1 sigma). Units are pCi/t for water, and milk except K is in mg/t. Units are total pCi for air particulate filters.

l l (b) Teledyne Results - Average i one sigma. Units are pC1/2 for water and l milk except K is in mg/l. Units are total pCi for air particulate filters.

(c) Units for food analysis are pCi/kg except K-40 which is mg/kg.

(d) No aerosol solution was added to the planchets in the final stages of preparation in order to create a more efficient counting geometry. The technicians in the alpha beta laboratory have been instructed to add the aerosol in accordance with Procedure PRO-031-1.

(e) No reason could be ascertained for the high result for Zn-65. Previous results had a normalized deviation from the known of -0.34 (10/10/86) and 0.58 (06/06/86). Therefore this does not appear to be a trend.

Further cross-checks will be studied for any problems.

(f) A new radiochemical method is being developed for this analysis which should give more accurate results.

(g) The previous two EPA beta results are 6 percent low, and our in-house beta spikes are low by about the s ue percentage. Dr. H. Jeter will re-train the analysts in transferring all sample residue into the planchets.

(h) The reported high result was due to small aliquot available for the Sr-90 analysis. Inadvertently a larger aliquot was used for another analysis leaving 40% of the nortnal volume for Sr-90. Additionally, the narrow acceptance limits defined by EPA is particularly difficult to meet. For this analysis 63% of the participants were beyond the t 3 sigma limit. -

(i) The low result is attributed to the application of the resin method rather than the hydroxide method to this analysis. The resin method is inefficient at absorbing protten-bound iodine thus leading to low results. The results obtained by GeLi were higher.

(j) The Cs-137 results in EPA Foods have typically been biased high. We are in the process of performing our annual calibrations. We are using a new Amersham mixed gamma standard rather than the most recently prepared NBS standard which is now several years old. Based on preliminary results the three Cs-137 values would be 52.1, 50.3, and 50.9, which average 51.1.

Notes: ( Co nt. )

(k) Erroneously high electrode reading of stable iodide in sample (possibly because of interfering species such as S--) leading to erroneously low chemical yields. Af ter repeating the electrode reading, the calculated average 1-131 is 49.6 pCi/t. Technicians have been made aware to be suspicious of high electrode readings. When unusually high readings occur samples will be diluted and/or oxidized and remeasured.

(1) A new Ra-228 analytical procedure is being evaluated as a corrective action to the variability of results with current method. Tl No. 12115 and Tl No.12116 (there was not sufficient sample for a third analysis) were also analyzed by the new procedure with results of 5.9 to 7.0 pCi/l. The new method will be used for the next Radium in Water Cross- '

check samples.

(m) The data for the Cr-51 results were reviewed. The detector efficiencies appear to be correct. The other five isotopes measured in this sample were within two standard deviations indicating there is no systematic error. Chromitsn-51 is difficult to measure at this activity level because of the low branching intensity of the gamma ray and being in the high background region of the spectrum since Cr-51 has a low energy ray, (n) The reason for deviation is due to uneven distribution of residue on planchet, resulting probably because of the omission of aerosol applica-tion. The residue from the original planchets was dissolved, evaporated

. and remounted using aerosol. The counting results then became accurate (2913, 30t3, 26t3). The analysts have been reminded to use aerosol when mounting evaporated liquids.

(o) The EPA sample was not analyzed. A newly trained technician misinter-

! preted the Sample Receipt Form and proceeded to dilute and analyze instead an in-house blank of deionized water. In the future, all dilutions will be performed by the laboratory supervisor or the laboratory manager to ensure accuracy.

APPENDIX G SNPS LAND USE SURVEYS 119

SNPS LAND USE CENSUS t

OPERATIONAL The operational program is required to comply with Section 3/4.12.2 of SNPS Technical Specifications. The technical specifications require a survey of all milk animals and gardens greater than 50m2 (500 ft2 )

producing broad leaf vegetation within a radial distance of 8 Km (5 miles).

LIL m is also required to identify the nearest milk animal, residence and garoen in each of the 16 meteorological sectors.

Environmental Engineering Department conducted the 1987 dairy animal census, during April through June. This survey was done by Environmental Technicians driving through each neighborhood within the 5 mile radial distance and visually checking for dairy animals. hhen a dairy animal was observed the technicians requested information from the owner concerning the amount of milk produced, feed, number of animals and grazing methods.

The 1987 census results indicated that there are no milk producing cows within a 5 mile radial distance from the site; however, the survey did locate the following milk, producing goats:

1. Sector 6,1.55 miles east-southeast of SNPS

. Mr. Frank Pitti Remsen Road Wcding River, New York 11792 REMP Monitoring Location - 681 (milk not being sampled; goats temporarily dried up (July 86)).

Inventory: 0 milking goats 3 non-milking goats Inventory Date: May 4, 1987

2. Sector 13,1.9 miles west of SNPS Poole Briarcliff Road Shoreham, New York 11786 REMP Monitoring Location 13B1 Inventory: 2 milking goats 6 non-milking goats Inventory Date: December 10, 1987 120

3. Sector 11, 2.40 miles southwest of SNPS '

Shoreham-Wading River School District Middle School Randall Road Shoreham, New York 11786 REMP Monitoring Location -11C1 (Milk not being sanpled due to owners decision not to participate).

Inventory: 3 milking goats 4 non-milking goats Inventory Date: May 6, 1986 t

Table G-1 lists the nearest milk animal in the sixteen meteorological sectors. Additional field survey data are filed in the Shoreham Record Retrieval System (SR2 A39.104) "Animal Census."

The Garden Census was also conducted by Environmental Engineering Technicians visually noting each garden of 50m2 (500 f tz) or greater.

The 1987 census was performed during July, August, September and October locating a total of 343 gardens. Table G-2 lists the nearest garden in the sixteen meteorological sectors. The field survey sheets and maps are filed i at Environmental Engineering Melville while a computer print listing each location is filed in SR2/A39.104 "Shoreham REMP Garden Survey 1987."

e Environmental Engineering identifies nearest residences by utilizing -

both aerial photography and visual confirmation. This years census was conducted in December. Table G-3 lists the nearest residence in ,

each meteorological sector.
