SUMMARY
o This report summarizes the Shoreham Nuclear Power Station (SNPS)
Radiological Environmental Monitoring Program (REMP) for 1986. SNPS received a 5% power license in 1985.
During 1986 the plant was shutdown except for a period between August 4 and September 2, when testing below 5% power resumed.
During the test period, the main turbine generator was synchronized to the grid for a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> run, t
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 population. The operational phase uses the preopera-tional baseline data to identify plant contributed radiation and evaluates the possible effects of rsdioactive plant effluents on the environment.
The SNPS REMP is designed to comply with the Plant's Technical Specifications and NRC Regulatory Guides.
The REMP data is acquired by sampling various media in the environment
~
which are then analyzed for any radiation present. Media sampled within the aquatic environment included surface water, algae, fish, invertebrates (clams, lobsters, etc.) and sediment. The atmospheric environment was sampled for airborne particulates, airborne iodine and noble gases. Milk, potable water, precipitation, game and food products were obtained from the terrestrial environment.
Direct radiation was measured using thermo-luminescent dosimeters (TLDs).
Radioactivity in environmental media varies from sample to sample as well as geographically; therefore, a number of sampling locations for each medium 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.
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 occurred at the on shore site for REMP location 13G2, at the entrance to Port Jefferson Harbor. During preoperational testing aquatic samples revealed low levels of iodine-131. An investigation revealed that the iodine-131 was from area hospitals treating patients for thyroid carcinoma.
A number of radioanalyses were performed on each medium sampled. All samples did not undergo all types of radioanalyses; only those analyses appropriate for the particular medium were performed.
The analyses included gamma spectrometry, strontium-89 and -90, iodine-131, tritium, gross beta radiation, direct radiation and noble gases.
2
On April 26, 1986 an accident occurred at the Soviet nuclear reactor Chernobyl Unit 4 at Prypat in the Ukraine resulting in fallout around the world. Various radioisotopes were measured in sample media collected at all the commercial nuclear utilities in the United States for which Teledyne Isotopes provides environmental analytical services. At SNPS the radio-activity was first detected during the week beginning May 5, 1986.
Elevated gross beta activity levels in weekly airborne particulates were measured from May 5 through June 10. The second quarter composite of airborne particulates analyzed by gamma ray spectroscopy had measurable levels of ruth 2nium-103, cesium-134, and cesium-137.
Iodine-131 was measured in weekly charcoal cartridges from May 5 through June 10.
Iodine-131 was also measured in milk samples collected between May 20 and July 14. Otherwise, REMP samples collected during 1986 exhibited normal concentrations of background radioactivity that have been observed in the Shoreham area over the past seven years.
Dose calculations for the SNPS environs were performed 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. The greatest contribution to dose can be attributed to direct radiation from cosmic and terrestrial sources.

THE PROGRAM 4
1 I
THE PROGRAM The Shoreham Nuclear Power Station's (SNPS) Radiological Environmental Monitoring Program (REMP) is conducted in compliance with NRC regulations, licensing ccmitments, 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 (transmitted to all Operating License Applicants by Steven A.
Varga, Acting Assistant Director for Light Water Reactors, Division of Project Management, on December 21,1979);
LILC0's Updated Safety Analysis Report (USAR) 11.6, Environmental Report (ER) 6.1.5 and Technical Specifica-tion Section 3/4.12. All samples were collected by personnel of the Long Island Lighting Company (Environmental Engineering and the Shoreham Opera-tions Departments) 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 8. More detailed information concerning sample locations and collection is available in REMP Procedure 1.0 Radiological Environmental Monitoring Program (REMP) Program Description.
During 1986 sample analyses were performed by Teledyne Isotopes (TI) of Westwood, New Jersey (referred to throughout the text as "the laboratory"),
under contract to LILCO. A summary of analytical results appears in Appendix A and individual analysis results in Appendix C.
A.

3.
Determine the long term variation in radionuclide concentrations or, 4.
Establish that the levels are insignificant.
5.
Determine the effects of plant effluent on the environment.
6.
Comply with regulatory requirements / specifications and provide records to document compliance.

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. Surf ace water samples were taken at six locations in May and October using a Niskin bottle. The samples rere placed in new polyetnylene bottles following three rinses with the sample medium prior to collection. Samples of Winter Flounder, Pseudopleuronectes americanus, Windowpane, Scophthalmus aquosus, Sea Robin, Prionotus spp, Little Skate, Raja erinacea, Blackfish, Tautog onitis and Summer Flounder, Paralichthys dentatus were taken by trawl, scaled in plastic bags, frozen, and shipped to the laboratory for analysis.
Invertebrate samples of American Lobster, Homarus americanus, Squid, Loligo pealeii and Channeled Whelk, Busycon canaliculata were collected by trawl. Channeled Whelk were also collected using pots.
These invertebrate samples were sealed in plastic bags, frozen and shipped to the laboratory 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 and 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 shipped. 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 particulates collected on Gelman Type A/E filters using icw 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 vacuum due to a leak the vacuum level reading will drop 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 corrected to standard pressure using average weekly barometric 6
pressure (measured at Environmental Engineering Department, Melville) and air sampler vacuum readings.
Time totalizers indicate the duration of time the sample 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 sample tank for transport to the laboratory for analysis.
3.
Terrestrial Environment The terrestrial environment was examined by analyzing samples 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 (NaHS0 ) preservative added.
3 Precipitation was collected at two locations weekly.
In order to ensure sufficient sample volume weekly precipitation samples were combined for a monthly sample composite.
Several precipitation grab samples were taken and analyzed during May and June to determine the extent of fallout due to the Chernobyl accident. Potable water was collected quarterly from three well locations.
Game samples (Squirrel, Sciurus carolinensis, Raccoon, Procyon lotor and Rabbit, Sylvilagus sp.) were also obtained semiannually from on site locations, sealed in plastic bags, frozen and then shipped. Food products consisting of vegetables and fruit were collected from area farm stands and shipped fresh to the laboratory. Soil samples comprizin each site) were collected at ten (10) locations,g 12-4"X3" cores (at sealed in plastic bags and shipped to the laboratory.
4 Direct Radiation Direct radiation levels in the environs were measured with energy compensated Calcium Sulfate (CaSO :Dy) TLDs, each contain-4 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 qua terly cycle, respectively. The units were then packaged and shipped to the laboratory for analysis.

Quality Assurance 1.
Teledyne Isotopes Teledyne Isotopes (TI) has an extensive quality assurance program designed to ensure the precision and accuracy of the data generated. An Interlaboratory Comparison Program is conducted with the Environmental Protection Agency (EPA). The results of the Program analyses are listed in Appendix E.
Participation in this program permits estimation of bias in TI results from the deviation from the "known" value given, or by comparison with means of all participants. The TI Quality Assurance Program for Radiological Monitoring is described in various TI publications (references 15, 16,17). Teledyne Isotopes " Quality Control, Internal Controls and Audits Environmental Analysis Department", IWL-0032-365 (reference
- 16) was revised and updated during 1986.
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.

Long Island Lighting Company a.
Nuclear Review Board (NRB) Audit The annual REMP NRB audit was conducted on October 20-24, 1986. As with last year's audit the 1986 NRB audit focused on internal LILC0 REMP activities in the Environmental and Nuclear Engineering, Nuclear Operations Support and Shoreham Operations Departments. LILC0 subcontractors were audited separately by LILCO's Quality Assurance (QA) Department. The Program areas audited were:
Quality Assurance, Compliance, Maintenance, Calibration and Standard-ization.
Audit Report NK-86-01 was issued on Ncvember 11 listing three (3) findings. No SNPS Technical Specification violations were cited in these findings. As of December 8, corrective action for one of the findings had been completed and accepted by LILC0's QA Department.
Proposed corrective actions for the other two findings have been accepted by LILC0's QA Department and were completed by April 1,1987.
b.
LILC0 Quality Assurance Audits 1.
Field Audit The REMP sampling effort has been audited by LILC0's QA Department since the beginning of the Program. The 1986 surveillances were conducted on March 25 (Precipitation and Noble G t), June 5 8
(Monthly TLDs), September 9 (Airborne Particulate / Iodine), October 30 (Aquatic-Surface Water, Invertebrate, Aquatic Sediment and Aquatic Plants) and December 22 (Potable Water).
No findings were noted during these surveillances.
2.
Environmental Radiological Laboratory Audit As with the REMP field sampling, the environmental radiological laboratory performing REMP radioanalyses has been audited annually since the start of monitoring. The laboratory utilized during 1986, Teledyne Isotopes, was audited on November 17-20, 1986. The audit team was comprized of representatives from the Quality Assurance, Environmental and Nuclear Engineering Departments. The 1986 audit reviewed Teledyne's existing QA program for compliance with Federal regulations and LILC0 specifications.
This years' audit identified four (4) findings requiring corrective action by Teledyne. Teledyne responded to these findings on December 19, 1986. The corrective and proposed preventive actions suggested by Teledyne have been accepted by LILCO, pending verification during the next audit.
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 Envirorrnental and Nuclear Engineering Departments.
Several factors are important in the interpretation of the data.
These factors are discussed here to avoid repetition in sections that follow.
Within tM 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 repetted analyses of the same sample would f all.
Tables C-21 and C-22 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 are calculated when applicable. The calculated standard deviations of grouped data represent sample rather than analytical variability.
For these calculations any values below LLD 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 caluclated.
9
l Grab sampling is a useful and acceptable procedure for taking environmental samales of a medium 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 sampled medium for that specific location and instant of time. As a result, variation of radionuclide concentra-tions in the samples will normally occur. Since these variations will tend to counterbalance one another, the extraction of averages based upon repetitive grab samples is valid.
2.
Gamma Isotopi: Analyses SNPS Techni:al Specifications Table 3.12.1-1 requires that analyses be performed on all media for gamma emitting radionuclides which may be attributable to the effluents from the plant. These analyses are in addition to requirements for specific gamma emitters such as I-131, Cs-134, Cs-137, Ba-140, Mn-54, Fe-59, Co-58, Co-60, 2n-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 whicn may be discharged when the LLD's for specified gamma emitters are met by this technique.
Tables 3.1 and 3.2 of the Shoreham Final Environmental Statement list the 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 gamma 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,Zn-69,Sr-91,Y-91m,Y-92,Y-93,Tc-99m, Rh-103m, Rh-105, Rh-106, Te-129, Te-131m, Te-131, I-132,1-135, Ba-137m, Pr-la3, Ce-143, Pr-144 and W-187).
2.
Those radionuclides with no gammas (P-32, Fe-55), those with a trivial percentage of their transitions going by gamma emission (Y-91), or those with their primary gamma occurring at such a low energy and at such low abundance that it is not routinely observable in the presence of other gamma activity (Nd-147).
With only 10 pCi of Nd-147 calculated to be released per year in Shoreham's liquid effluents, the nuclide cannot be an important contributor to dose.
10
E.
Dose Assessment In order to assess the total dose an individual may receive from the Shoreham environment, appropriate environmental samples, located along critical effluent pathways, are analyzed for the presence and total activity and quantity 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 q
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.
Raolonuclides may enter the body through ingestion of water and milk, inhalction of and immersion in air, submersion in water, or l
consumption of food. Thus, in order for the REMP to provide an estimate of the total radiation dose, a radionuclide intake is determined 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. 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 dose for the year. Additional information, such as the quantity of fish, milk, water, meat, vegetables, etc., consuned 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 TLDs.
The 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 factor 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 The sample concentration is typicaly expressed in pCi/A or pCi/kg.
For the ingestion pathway, the quantity ingested or consumed per year is expressed in kg/ year or f/ year.
Finally, the dose conversion factor is expressed in terms of mrem /pCi ingested or inhaled.

RESULTS AND DISCUSSIONS 1
n 15
RESULTS AND DISCUSSION The analytical results for the reporting period of January 1 through December 31, 1986 have been divided into four categories: aquatic, atmospheric, terrestrial, and direct radiation. The individual samples 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.
The accident at the Soviet nuclear reactor Chernobyl Unit 4 at Prypat in the Ukraine resulted in fallout around the world. Various radioisotopes were measured in sample media collected at all the commercial nuclear utilities in the United States for which Teledyne Isotopes provides environ-mental analytical services. At the Shoreham Nuclear Power Station the radioactivity was first detected during the week beginning May 5, 1986.
Elevated gross beta activity levels in weekly airborne particulates were measured from May 5 through June 10.
The second quarter composite of airborne particulates analyzed by gamma ray spectroscopy had measurable levels of Ru-103, Cs-134, and Cs-137.
Iodine-131 was measured in weekly charcoal cartridges from May 5 through June 10.
Iodine-131 was also measured in milk samples collected between May 20 and July 14.
A.
Aquatic Environment The aquatic environment in the vicinity of SNPS consists primarily of Long Island Sound.
The radiological characteristics were studied by analyzing samples of surface water, Winter Flounder, Windowpane, Sea Robin, Little Skate, Blackfish, Summer Flounder, American Lobster, Squid, Channeled Whelk, Blue Mussels, Sof t Shell Clams, aquatic plants and sediment. The samples were collected by LILC0 Environmental Engineering and EA Engineering Science and Technology Inc. (under contract to LILCO).
1.
Surface Water (Table C-1)
Semiannual surface water samples were taken at six locations and were analyzed for tritium, gamma emitters, iodine-131, and strontium-89 and strontium-90.
Four surf ace water samples analyzed for tritium showed detectable levels between 120 and 280 pCi/f with an average of 188 pCi/t. The other eight samples were below the lower limit of detection. This is consistent with tritium concentrations observed in surface water during 1983 and 1984, the preoperational period, and in 1985.
16
Naturally occurring potassium-40 was measured in eleven of the samples with an average of 258 pCi/A and a range between 96 and 387 pCi/A.
Cesium-137 was detected at the low level of 6.4 pCi/A at location 4A3 for the May 14 collection. No other gamma activity above the detectable levels was measured in the twelve surface water samples as analyzed by gamma spectroscopy.
Surface water samples were also analyzed for iodine-131, strontium-89, and strontium-90. None of these nuclides were observed within the limits of detection.
2.
Fish (Table C-2)
Twenty-eight fish samples were collected at three locations and the edible portions analyzed for gamma emitters. Gamma spectrometry showed potassium-40 present in all samples with an average concentration of 3495 pCi/kg wet and a range between 2290 and 5190 pCi/kg wet. Cesium-137 was detected in four samples with an average activity of 12.6 pCi/kg wet and i
a range between 10.2 and 13.8 pCi/kg wet. These activities are less than those reported in 1983 and 1984 during the preoperational period, and comparable to those reported in 1985.
3.
Invertebrates (Table C-3) i Twenty-three invertebrate samples, comprised of soft shell clams, l
mussels, lobsters, squid, and whelks, were collected at six locations and analyzed for gamma emitters, strontium-89 and strontium-90. Gamma l
spectrometry showed detectable levels of potassium-40 in all samples, ranging from 1900 to 4840 pCi/kg' wet with an average activity of 2567 pCi/kg wet. Naturally occurring beryllium-7 was measured in one sample with an activity of 70.4 pCi/kg wet. Strontium-89 was not observed, however, strontium-90 was observed in one sample with an activity of 5.6 pCi/kg wet.
4.
Aquatic Plants (Table C-4)
Marine algae, collected at five locations (ten samples) in Long Island Sound and at one location in Wading River Marsh (two samples), were analyzed for gamma emitters and strontium-89 and strontium-90.
Gamma spectrometry showed detectable potassium-40 in all samples ranging from 4960 to 32900 pCi/kg dry with an average of 13287 pCi/kg dry.
Cosmogenically produced beryllium-7 was measured in five of the samples ranging from 311 to 1780 pCi/kg dry with an average activity of 775 pCi/kg dry.
Cesium-137 was measured in one sample with an activity of 47.9 pCi/kg dry. Naturally occurring thorium-228 was measured in eight samples with an average activity I
of 412 pCi/kg dry and a range of 133 to 997 pCi/kg dry. Radium-226 was measured in four samples with an average activity of 889 pCi/kg dry and a range of 465 to 1230 pCi/kg dry.
Strontium-90 was measured in one sample with an activity of 13 pCi/kg dry. Strontium-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 (Table C-5)
Eight offshore sediment samples were collected in May and October at four offshore locations and analyzed for gamma emitters and strontium-89 and strontium-90. Gamma spectrometry showed detectable levels of potassium-40 in all samples ranging from 2000 to 8280 pCi/kg dry with an average activity of 4245 pCi/kg dry. Naturally occurring radium-226 was observed in one sample with an activity of 1210 pCi/kg dry. Thorium-228, also naturally occurring, was measured in seven samples within the range of 192 to 1010 pCi/kg dry with an average activity of 494 pCi/kg dry. All other gamma emitters, were below the lower limit of detection. No strontium-89 or strontium-90 was detected in these samples.
Twelve beach sediment samples were collected and analyzed for strontium-89, strontium-90 and gamma emitters. No strontium was detected.
All samples had measurable activities of naturally occurring potassium-40 with an average activity of 3182 pCi/kg dry and a range of 1830 to 7180 pCi/kg dry. One sample had measurable radium-226 with an activity of 922 pCi/kg dry. Six samples had measurable thorium-228 with an average activity of 258 pCi/kg dry and a range of 69.5 to 832 pCi/kg dry. All other gamma emitters were below the lower limit of detection.
B.
Atmospheric Environment The atmospheric environment in the vicinity of the SNPS was examined by analyzing samples of airborne particulates and airborne iodine at 16 sampling locations. TEDA-impregnated charcoal cartridges used to collect airborne iodine were collected weekly and analyzed by gamma spectrometry for iodine-131. Airborne particulate filters were collected weekly and analyzed for beta emitters. Quarterly composites from each station were analyzed for gamma emitters and radiostrontium.
1.
Airborne Particulates (Tables C-6, C-7, C-8 and C-9)
During the five week period of May 6 through June 10 elevated gross beta activities, attributed to the Chernobyl accident were measured at all 16 sampling locations with wegkly average concentrations of 0.300, 0.207, 0.055, 0.154, and 0.104 pCi/m3 respectively.
For the week of highest gross beta activity the individual sampling locations had a range of 0.240 to 0.380 pCi/m3 During the remaining 47 weeks of 1986 the gross beta activity was measured in 741 of the 752 samples collected with an average concentration of 0.016 pCi/m3 and a range from 0.004 to 0.032 pCi/m3 The results of the gross beta analyses are listed in Table C-6.
The monthly averages of the gross beta concentrations are plotted in Figure 2 from January 1, 1977 through December 31, 1986. Results of gamma spectrometry (Table C-8) showed detectable levels of naturally occurring beryllium-7 in all 64 samples.
The average beryllium-7 activity in the quarterly analyses was 0.0878 pCi/m3 Naturally occurring potassium-40 was obseryed nine times. The potassium-40 had an average activity of 0.013 pCi/md.

In the second quarter composites the following four fission-produced isotopes were measured (with the number of locations in parentheses):
ruthenium-103(16), ruthenium-106(1), cesium-134(15),andcesium-137(16).
TheseisotopesareattributedtotheCgernobylaccident. The average ruthenium-1Q3 activity was 0.010 pCi/m and the range was from 0 0 The single ruthenium-106 actlyity was 0.013 pCi/m3.081 to 0.013 pCi/m3 The average cesium-134 activity was 0.0090 pCi/mJ and the range was from 0.0070to0.011.pC1/mJ.Theaveragecesium-g37activitywas0.021pCi/m3 and the range was from 0.015 to 0.025 pCi/m.
In compliance with SNPS Technical Specification Table 3.12.1-1, individualairbornegarticulatefilters,whichhadagrossbetaactivityin excess of 0.17 pCi/m (ten times the ave. rage 1985 background gross beta activity measured at site 11G1), were analyzed by gamma spectroscopy. This resulted in measuring each of the 16 locations for the weeks beginning May 6 and May 13 and three locations for the week beginning May 27.
In the table below is a summary of the results for the average for all locations of each isotopes:
Collection Dates Ru-103 I-131 Cs-134 Cs-137 4

The radiostrontium analyses (Table C-9) on the 64 quarterly composites showed no detectable levels of strontium-89 or strontium-90 in the first, I
third, and fourtn quarters of 1986. The lower limit of detection (LLD) for strontium-90 is IX10-4 pCi/m3 In the second quarter, strontium-89 and strontium-90 were measured in several composite samples and attributed to the Chernobyl accident.
Strontium-89 was detected in eight of the indicator locations and in all four of the co trol locations with an average for all twelvt measurements of 0.0015 pCi/m and a range from 0.00095 to 0.0025 pCi/m.
Strontium-90 was detected in five of the indicator locations and l
J in two of the control locations with an average of 0.00018 pCi/m3 and a 3
range from 0.00011 to 0.00027 pCi/m.

2.
Airborne Iodine (Table C-10)
Results of airborne iodine-131 analyses of charcoal cartridges are presented in Table C-10.
Iodine-131 attributable to the Chernobyl accident was detected in all 16 sampling locations during the two week period May 6 through May 20, in 10 locations during the week ending May 27, in eleven locations during the week ending June 3, 1986 and in only one location during the week ending June 10, 1986. The avera was 0.84, 0.32, 0.082, 0.098, and 0.035 pCi/m3, ge concentration per week respectively.
In sub-sequent weeks as the iodine-131 continued to decrease due to radioactive decay and atmospheric mixing, the concentrations dropped below the detection limit. During the remaining 47 weeks of 1986, no iodine-131 was detected above the lower limit of detection.
3.
Noble Gas (Table C-20)
Air samples 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 samples had positive concentrations of Krypton-85 r pCi/mJ, with an average concentration of 29 pCi/m3,anging from 21 to 48 C.
Terrestrial Environment The terrestrial environment in the vicinity of the SNPS was examined by analyzing samples of game (raccoon, rabbit and squirrel), milk, food products, rainwater and potable water and soil. Gamma spectrometry was performed on all samples.
In addition, iodine-131, strontium-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. Soil samples were analyzed for gamma emitters and strontium-90.
1.
Nilk (Tables C-12 and C-13)
As a result of the Chernobyl accident, the radiochemical separation analytical method for iodine-131 detected four positive measurements from indicator locations and six positive measurements from control locations in samples collected from May 20 through July 16.
The average was 7.6 pCi/l and the range was from 0.97 to 26 pCi/f.
The remaining 59 milk samples analyzed for I-131 were below the LLO which ranged between 0.2 and 0.5 pCi/f.
Naturally occurring potassium-40 was observed in all the milk samples ranging from 984 to 1840 pCi/l for cow milk and 1060 to 2160 pCi/l for goat milk.
Beginning in June cesium-137, attributed to Chernobyl, was detected in 14 of the 35 cow milk samples with an averagt concentration of 9.8 pCi/t and a range from 7.3 to 17.7 pCi/f.
Cesium-137 was also detected in 7 of the 34 goat milk samples with an average concentration of 8.1 pCi/l and a range 23
from 6.7 to 10.3 pCi/t. All other gamma emitters, as well as strontium-89 were below the detection limit. All of the milk samples had measurable strontium-90 activity.
In the 22 cow milk samples, the average strontium-90 concentration was 6.6 pCi/A and the range was from 1.3 to 13 pCi/f. For the 24 goat milk samples, the average strontium-90 concentration was 2.5 pCi/t and the range was from 0.98 to 6.2 pCi/t. The activities reported for strontium-90 are consistent with those found in cow and goat milk during 1983, 1984 and 1985.
2.
Potable Water (Table C-14)
Tritium activity was observed in seven of the twelve potable water samples with activities ranging from 130 to 420 pCi/A and an average activity of 189 pCi/f. The other tritium analyses were below the lower limit of detection. This is consistent with the results of 1983, 1984 and 1985.
No iodine-131 was measured above the lower limit of detection, which was between 0.1 and 0.5 pCi/f. Naturally occurring potassium-40 was observed in two samples with an average activity of 21.3 pCi/A and a range of 12.1 to 30.4 pCi/t. Thorium-228 was observed in one sample with an activity of 14.6 pCi/t.
All other gamma emitters were below the lower limit of detection.
3.
Game (Table C-15)
Potassium-40 was observed in the six game samples with nearly the same activity level ranging from 2430 to 4430 and an average activity of 3458 pC1/kg wet. However, cesium-137, the only other observed gamma emitter, was measured in greatly different activity levels in squirrels versus raccoons and rabbits due presumably to differences in diets.
The squirrel samples had an average cesium-137 activity of 2475 pCi/kg wet, while the two raccoon samples had an average cesium-137 activity of 550 pCi/kg wet. The two rabbit samples had an average cesium-137 activity of 71.25 pCi/kg wet.
These results are consistent with results of 1983, 1984 and 1985.
All other gamma emitters were below the lower limits of detection.
4 Food Products (Table C-16)
Seventy-six human food products from local f arms were analyzed, including tomatoes, potatoes, cabbage, lettuce, beets, radishes, spinach, onions, scallions, strawberries, carrots, and corn. All samples contained naturally occurring potassium-40 with an average of 2659 pCi/kg wet and a range of 815 to 5910 pCi/kg wet.
Samples were also analyzed for iodine-131 by the radiochemical procedure and it and was observed in one of the seventy-six samples with an activity of 15 pC1/kg wet.
The iodine-131 is attributed to Chernobyl f allout since the one positive results was at a control location.
Four samples had beryllium-7 activity with an average concentration of 198 pCi/kg wet and a range of 128 to 242 pCi/kg wet. All other gamma emitters were below detection limits.
24
5.
Precipitation (Table C-11)
Thirty precipitation samples were collected at two stations during the twelve months and analyzed for gross beta, tritium and gamma enitters.
Gross beta activity was measured in 28 of the 30 samples with an average activity of 9.8 pCi/t.
Tritium was measured in 6 of the 30 samples with an average activity of 153 pCi/A and a range of 120 to 190 pCi/t. This is consistent with tritium levels in 1983 thru 1985.
Naturally occurring beryllium-7 was observed in ten samples with an average activity of 111 pCi/f and a range of 19.7 to 237 pC1/2.
Iodine-131 was observed by gamma spectroscopy in four samples with an average activity of 33.5 pCi/t and a range of 23.8 to 52.5 pct /t. Cesium -137 was observed in two samples with an average activity of 6.9 pCi/t and a range of 1.4 to 12.4 pCi/A. All other gamma emitters were below detection limits.
6.
Soil (Table C-17)
Soil samples were collected in November at ten locations and analyzed for strontium-90 and gamma emitters.
Strontium-90 was detected in eight samples with an average activity of 17.5 pCi/kg dry and a range of 8.9 to 37 pCi/kg dry. Gamma spectrometry showed detectable levels of potassium-40 in all samples ranging from 23:0 to 7620 pCi/kg dry with an average activity of 4257 pCi/kg dry.
Naturally occurring radium-226 was measured in seven samples with a range of 563 to 1980 pCi/kg dry and an average activity of 970 pCi/kg dry. Thorium-228, also naturally occurring, was measured in all samples with a range of 471 to 1450 pC1/kg dry and an average activity of 679 pC1/kg dry. Cesium-137 was measured in eight samples with a range of 157 to 475 pC1/kg dry and an average of 269 pCi/kg dry. All other gamma emitters were below the lower limit of detection.
D.
Direct Radiation (Tables C-18 and C-19)
Direct radiation measurements were taken monthly and quarterly at 36 locations using CaSO.;:Dy thermolurninescent dosimeters (TLDs).
TLDs were used to detect radiation levels near ground level in the vicinity of the Shoreham site due to terrestrial and cosmic gamma ray emitters and possible SNPS contributed direct radiation. Figure 3 presents a comparison of 1
average TLD results from 1977 to 1986. 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 of the quarterly exposures was 3.8 mR/ standard month and the average of the monthly exposures was 3.9 mR/ standard month. This is less than quarterly and monthly values, respectively, measured during the pre-operational years 1983 and 1984.

Dose Assessment Table 2 sunmarizes the results of the dose assessment determinations based on 1986 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 the Chernobyl accident as possible, indicator and control sample results were compared, if the control location results were comparable to or greater than those at the indicator location, then the indicator sample results were not included in the dose assessment. Surface water, aquatic plants and precipitation were not considered as human exposure pathways and, therefore, not considered in the dose assessment. The dose due to standing on contaminated soil was not calculated since this is accounted for in the direct radiation dose.
Beryllium-7, potassium-40, radium-226 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 ingesteo and is included in the direct radiation component. The remaining positive isotopes, cesium-137, strontium-90, ruthenium-106 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. Cesium-137, ruthenium-106 and strontium-90 have also been measured in the environment as a result of the Chernobyl accident.
Since ruthenium-106 was measured in only two airborne l
particulate samples immediately after the Chernobyl accident, it was decided not to include it in the dose assessment.
Ccmparison of the results of the dose assessment of 1966 with those of the preoperational years 1983 and 1984, show similar results for all three years.
The direct radiation dose in 1986 (Appendix A) was less than in 1983 and 1984.
Doses calculated for 1983 were based on ingestion factors for the average individual, whereas the maximum individual ingestion factors were used in 1984 and 1986.
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 1986 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 29
CONCLUSIONS During 1986 the Shoreham Nuclear Power Station conducted tests at power levels below 5% between August 4 and September 2, and was shutdown for the remainder of the year.
The accident at the Chernobyl nuclear reactor in Russia contributed ceasurable amounts of radioactivity to the environment. By comparison of results for indicator and control locations, most of the positive results for possible plant generated radionuclides can be attributed to Chernobyl 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 radioactive f allout 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.
1 j
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 i
represents the average weekly gross beta results in airborne particulates from January through December 1986. Figure 2 shows the average monthly gross beta results in airborne particulates from February 1977 to December 1986.
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 1986.

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

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:
4-5 miles off site On site location E
S
=
=
5-10 miles off site 0-1 miles off site F
A
=
=
10-20 miles off site 1-2 miles off site G
B
=
=
>20 miles off site 2-3 miles off site H
C
=
=
3-4 miles off site 0
=
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.
(1) A more specific means of classification will be noted in the comment section of each laboratory report for these samples.
For example, AQI will be designated, in the sample description, as aquatic invertebrate.
However, the comment section will specify the sample type by the generally accepted common name of the sample involved.
In this case, clam, lobster, crab or other aquatic invertebrate would be listed in the comment section.

APPENDIX B Sampling Locations Maps B-1, B-2 and B-3 show the locations of sampling stations with respect to the site. These maps are tracings of portions of larger maps prepared by LILC0'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 contacting either LILC0's Environmental Engineering Department or Survey Division.

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.
99
p 2.0 DETECTION CAPABILITY i~,
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 minimurn detectable level (MOL) for water sampler.gis nominally 1.6 picocuries per liter for gross beta at the 4.66 sigma level (1.0 pCi/t at the 2.83 sigma level), assuming that I liter of sample is used and that 1/2 gram of sample residue is mounted on the planchet. These figures are bated 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 4
efficiency of 0.02 and a background of 0.1 cpm.
The MOL becomes significantly lower as the mount weight decreas s because of reduced self-absorption. At a zero mount weight, the 4.66 sigma MOL for gross beta is 0.9 picocuries per liter. These values reflect a beta counting efficiency of 0.38 and an alpha counting efficiency of 0.18.

Af ter a delay of five or more days, allowing for the radon-222 and radon-220 (thoron) daughter products to decay, the filters are counted'in a gas-flow proportional counter. An unused air particulate filter, supplied by LILCO, is counted as the blank.

ANALYSIS OF SAMPLES FOR TRITIUM Water Approximately 2 ml of water are converted to hydrogen by passing the water, heated to its vapor state, over a granular zinc conversion column heated to 400* C.
The hydrogen is loaded into a one liter proportional detector and the volume 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.

ANALYSIS OF SAMPLES FOR STRONTIUM-89 AND -90 Water Stable strontium carrier is added to 1 liter of sample cnd the volume is reduced by evaporation.
Strontium is precipitated as Sr(NO )2 using 3
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.
Yttrium is then precipitated as hydroxide, is dissolved and re-precipitated as oxalate. The yttrium oxalate is mounted on a nylon planchet and is counted in a low level beta counter to infer Sr-90 activity.

GAMMA SPECTROMETRY OF SAMPLES Milk and Water A 1.0 liter Marinelli beaker is filled with a representative aliquot of the sample. 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 pu!se 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 and 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 300 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 I-131) uniquely from the volume of air which passed through it.
In the event I-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.

Teledyne Isotopes uses a CaSO :Dy thermoluminescent dosimeter (TLD) 4 which the company manufactures. This material has a high light output, negligible thermally induced signal loss (fading), 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 TLD is heated at a time is recorded. The TLD is then annealed and exposed to a known Cs-137 dose; each area is then read again.
This provides a calibration of each area of each TLD after every field use.
The transit controls are read in the same manner.

(g) The spike level in this case was at a low activity. The three results were 1.4 i 0.6, 1.4
- 0.6 and 1.3 i 0.6.
At this activity level the counting error is relatively high.
If the counting error is taken into consideration, these results were within the 2 sigma deviation of 1.7-2.3 pCi/A.
(h)
These air filters are counted for gross alpha, beta and gamma before being analyzed for Sr-90.
It was felt that some of the activity had been lost in handling. The air particulate filters will be handled more carefully in the future. This had not been a problem in previous analyses.
(1) A new set of standards was prepared to check the efficiency of the Alpha Counters. Two new counters were prepared and the existing counters cleaned or resurfaced. A new set of efficiencies were determined.
(j) The efficiency calibration for Cs-137 for the gamma spectrometer detec-tors was checked and no reason for the high result was evident. Previous analyses did not exceed the 2 sigma limits.
If this situation recurs, a new efficiency for Cs-137 will be determined.
(k)
For Sr-90 fourteen of the seventeen laboratories participating were beyond the i 3 sigma level. For Sr-89 thirteen of the fifteen labor-atories had low results.
It would appear that the sample is flawed in some way for this analysis.
(1) This analysis was performed by an inexperienced technician who has since received additional training and is performing satisfcctorily.
(m)
It is believed that too much Na2003 was used in the final precipitation of SrC03 resulting in a falsely high strontium-89 yield.
Less Na2003 will be used in the future precipitation of SrC0 -
3 (n) The data for the samples was examined and no obvious re? ton for the high result could be found. The Cs-137 calibration was checked and found to be in agreement with previous readings.
Since this was not a trend in previous analyses for Cs-137 in Water (Test 418 -0.023; Test 406 -0.11) it was decided to follow the results to see if a trend developed.

An investigation is being conducted and an explanation will be available shortly.

SNPS LAND USE' CENSUS 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 gardensx greater than 50n2 (500 ft )
2 producing broad leaf vegetation within a radial distance of 8 m (5 miles).
LILCO is also required to identify the nearest milk animal, residence and garden in each of the 16 meteorological sectors.
p.,
Environmental Engineering Department conducted the 1986 dairy animal census, during March through May. This survey was done by Environmental Technicians driving through each neighborhood within the 5 mile radial distance and visually checking for dairy animals. When 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 1986 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:

" Animal Census."
The Garden Census was also conducted by Environmental Engineering 2 (500 ft ) or greater.
2 Technicians visually noting each garden of 50m The 1986 census was performed during July, August and September locating a total of 277 gardens. Table G-2 lists the nearest garden in the sixteen meteorological sectors.
The field survey sheets and maps are filed at Environmental Engineering Melville while a computer print listing each location is filed in SR2/A39.104 "Shoreham REMP Garden Survey 1986."
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.
