w Executive Summary The Radiological Environmental Monitoring Program for Seabrook Station operated without interruption for the period of January through December 1993. During the year, samples collected as part of the radiological environmental program included air particulates, charcoal filters, milk, ground water, surface (sea) water, sediment, fish, lobsters, shellfish and direct radiation. Radiological analysis on all samples included that for gamma and/or beta radiation. Any variability observed in the data is based primarily on a number of natural variables that can influence background radiation.
The radionuclides identified as naturally occurring are K-40, Be-7, Th-232 and its daughter products.
Cesium-137 was detected in milk as the result of fallout from atmospheric nuclear weapons testing.
The levels detected are consistent with those measured during the preoperational phase of the monitoring program.
During 1993, Seabrook Station had a capacity factor of 89.8%. This included 120 days of continuous operation with five unplanned shut downs ranging in duration from 1.5 to 8 days. No refueling operations occurred in 1993.
During 1993, the maximum whole body dose to the hypothetically exposed individual was 0.0014 millirem. This whole body dose is the sum of all the exposure pathways for liquid and gaseous effluents, plus the direct whole body dose from station operations. This total dose represents 0.01%
of the whole body dose limit for a member of the public as set forth in 40CFR190. The complete calculational methodology was submitted to the NRC as part of the Annual Radioactive Effluent Report.

l' ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT l 1.0 Introduction The North Atlantic Energy Service Corporation's (NAESCO) Radiological Environmental Monitoring Program at Seabrook Station has been designed and carried out to achieve the follov.ing specific objectives:
l To provide an indication of the appearance or accumulation of any radioactive material in the environment caused by the operation of the nuc! ear power station.
To provide assurance to regulatory agencies and the public that the station's environmental impact is known and within anticipated limits.
l To verify the adequacy and proper functioning of station effluent controls and morkoring systems.
l To provide standby monitoring capability for rapid assessment of risk to the general public in the event of unanticipated or accidental releases of radioactive material.
North Atlantic Energy Services Corporation collected the terrestrial samples and processed the environmental thermoluminescent dosimeters (TLDs). Normandeau Associates, Inc, collected the marine and sediment samples. After the initial processing, the samples were sent to the Yankee Atomic Environmental Laboratory in Westboro, Massachusetts for further processing and radionuclide analysis.
This report is a summary of the finding of the Radiological Environmental Monitoring Program for 1993. It is being provided in compliance with plant Technical Specification 6.8.1.3.

l 3.0 Summary of Radiological Environmental Data The following pages summarize the analytical results of the environmental samples which were collected in 1993. Each environmental media category is present as a separate subsection. A discussion of the sampling requirements and results for each program is followed by a table which summarizes the data. At the top of each table are listed the units of measurement for each medium. The left hand column contains the radionuclide which is being reported, total number of analyses of that radionuclide, and the number of measurements which exceeds ten times the yearly average of control measurements. The latter are classified as "non- routine" measurements. The next column lists the Lower Limit i of Detection (LLD) for those radionuclides which have detection capability requirements specified in the Off-Site Dose Calculation Manual. l Those sampling stations which are adjacent to the plant and which could conceivably be l affected by the operation of Seabrook Station are called " Indicator" or " Zone 1" stations. [ Distant stations, which are beyond plant influences are called " Control" or " Zone 2" stations. Direct radiation (TLD) monitoring locations are subdivided into site boundary, inner ring, and l outer ring (emergency response) stations. l A set of statistical parameters is calculated for each radionuclide. This set of statistics'
- parameters includes separate analyses for (1) the indicator stations, (2) the control stations, l and (3) the station having the highest annual mean concentration for that radionuclide. For l each of these three groups of data, these parameters are as follows
1 The mean value of all concentrations. The standard error of the mean. The lowest and highest concentration. l l The number of positive measurements (a concentration which is greater than the a posteriori LLD for that analysis) divided by the total number of measurements. Each single radioactivity measurement datum in this report is based on a single measurement and is reported as a concentration plus or minus a one standard deviation uncertainty. The quoted uncertainty term represents only the random uncertainty associated with the radioactive decay process (counting statistics), and not the propagation of all possible uncertainties in the analytical procedure. Attachment I contains the data for the samples collected in 1993. The results are organized by sample type, within each sample type listing the data is alphabetical by nuclide, within each nuclide listing the data is chronologically arranged by end date (date of sample l collection). l The Radionuclide concentration values for all media except for lodine-131 airborne I concentrations (charcoal media) have been corrected for radioactive decay to the end of the collection. The airborne radiciodine (charcoal) concentrations have been calculated assuming a constant flow rate and concentration throughout the collection period and correcting for decay while sampling as well as between sample collection termination and analysis. Pursuant to ODCM requirements, any concentration below the LLD for its analysis is i reported as "not detected" These values are set to zero for averaging purposes. Where a i range of values is reported in the tables of this section, values less than the a nosteriori LLD for the analysis are reported as zero. 13
A) Air Particulate Air monitoring stations were established at a total of eight locations (five are required by the Offsite Dose Calculation manual). Seven of these locations are indicators, while the remaining one is a control station. Airborne particulates are collected by passing the air through a glass-fiber filter. These filters are collected weekly and held for at least 100 hours before being analyzed for gross-beta activity (indicated as GR-B in tables) to allow for the decay of radon daughter products. Quarterly composite air filters from each location are analyzed for gamma emitting radionuclides. Naturally occurring Be-7 was the only nuclide detected. No air sample was available from station No. 8 for the last week of March. This was the , result of the power supply (PSNH substation) exploding and burning. Sampling was resumed l the following week as power was restored through the use of a temporary substation. There were no samples available from air monitoring station No. 4 for weeks 21 and 23 of the year (May 26 and June 9 collection dates). The lack of air monitoring samples was the result of an inadvertent shutoff of electrical power. This situation has been rectified by a tag out of the electrical circuit breaker in question. The electrical breaker for this air monitor has also been isolated to preclude inadvertent power shutoffs. . l No sample was available during week 34 (August 25,1993 changeout) at sample station No.
- 2. It was discovered that the circuit breaker had tripped. The circuit breaker was reset at the time of the next change-out. No further action was taken or needed. l l

B) Charcoal Filters Charcoal filter cartridges are in series with the air particulate glass-fiber filters. Monitoring stations were established at a total of eignt locations (five are required by the ODCM). Seven of these are indicators and one is a control. Charcoal filters from the air sampling stations were collected and analyzed weeldy for I-131 activity. During 1993, no I 131 was detected on charcoal filters. 1 19 L ... .

1 C) Milk Milk samples were collected every two weeks during the pasture season and monthly at other times. Samples are analyzed for I-131 and gamma-emitting radionuclides. Detectable concentrations of Cs-137 was measured in several san.ples collected in 1993. It has been shown in the preoperational program that this nuclide is the result of atmospheric nuclear weapons testing that persists in the environment. The levels of Cs-137 detected in 1993 are consistent with that detected in the pre-operational phase. Potassium-40 is a naturally occurring nuclide detected in the milk samples. Samples were unavailable from station TM-10 f.om January 27, through March 25 and from September 9 through the end of the year. This is due to yearly shutdown of milking operations at the Goldenwood Farm (TM-10). Milking operations will re-commence in the spring of 1994. l 1 l l 1 21

K) Direct Radiation Direct gamma radiation exposure was measured with thermoluminescent dosimeters (TLDs). Two TLDs were placed at each of the monitoring stations. (Each TLD has 3 CaSOgTm elements). A total of forty stations were required. All badges were collected and readout on a quarterly schedule. All exposure rates were normalized to a 914ay quarter, A summary of the data is shown in Table 3.1, No unusual readings were detected. I i 48

4.0 Quality Assurance Program North Atlantic has conducted a quality assurance program at Seabrook Station to ensure the results of the direct radiation measurements, as well as, the collection of samples. The environmental dosimeters are processed by the station dosimetry group which is a National Voluntary Laboratory Accreditation Program (NVLAP) certified laboratory. l Procedures have also been established and training conducted to address quality control in the sampling process. Yankee Atomic Environmental Laboratory (YAEL) participates in the EPA Interlaboratory Comparison (cross-check) program for those species and matrices routinely analyzed by the laboratory. This provides an independent check of accuracy and precision of the laboratory analysis. 1 When the results of the cross-check analysis fall outside the control limit, an investigation is made to determine the cause of the problem, and corrective measures are taken, as appropriate. YAEC maintains an intralaboratory quality control program to assure the validity and reliability of the data. This program includes quality control of laboratory equipment, use of reference standards for calibration, and analysis of blank and spiked samples. The records of the quality control program are reviewed by the responsible cognizant individual, and corrective measures are taken whenever applicable. A blind duplicate program is maintained in which paired samples from five nuclear plants, including Seabrook Station, are prepared from homogenous media and sent to the laboratory for analysis The results from this blind duplicate program are used to check for precision in laboratory analyses. Intralaboratory and EPA Interlaboratory Results The Quality Assurance Program implemented at the analytical laboratory indicated good precision and accuracy in reported values. Table 4.1 shows the results of accuracy and precision for laboratory analyses in 1993 for intralaboratory analyses and EPA interlaboratory cross-check analyses. 60
The resues of the EPA Interlaboratory Comparison Program, when considered apart from the remainder of the Quality Assurance Program, were satisfactory with respect to accuracy and precision. As indicated in Table 4.2,129 analyses were performed on air particulate filters, milk, and wate-r. There were initial questions on two preliminary results: Barium-133 (June 11,1993) and Ruthenium-106 (November 12,1993) for water. For the set of Ba-133 measurements for the water sample with EPA Reference Date of 6/11/93: The YAEL mean value of 59.36 pCi/L fell below the EPA control limit of 81.7-116.3 pCi/L. j This radionuclide is not in the gamma software library. Consequently, the Ba-133 results for ' the EPA sample set were calculated manually using the 356 kev photopeak. A review of the sample paperwork indicated that the hand-calculated radioactivity concentrations did not incorporate the 60 percent gamma-ray abundance factor required for the 356 kev photopeak. A recalculation of the Ba-133 activity concentration using this factor yielded a mean value within the EPA control limits. For the set of Ru-106 measurements for the water sample with EPA Reference Date of 11/12/93: The YAEL mean value of 165.53 pCi/L fell below the EPA control limit of 166.3-235.7 pCi/L. The YAEL considers the EPA known value to be suspect since the grand mean of 175.18 pCi/L is -12.8 percent below the EPA stated known value of 201 pCi/L. Assuming the grand mean is the actual activity concentration, the YAEL mean result of 165.53 pCi/L would have a bias difference of only -5.5 percent. A subsequent internal process check analysis of an EPA Ru-106 standard supplied by the EPA to validate the process indicated a mean value within 2 percent of the known. The process is considered in compliance at this time. Based on these further analyses, all samples met the EPA control limit criteria. The above Interlaboratory Comparison Program results are provided in compliance with Technical Specification 4.12.3. Blind Duplicate Procram A total of 50 paired samples (Table 4.3) were submitted by the five YAEL sponsor company plants for analysis during 1993. The data base used for the duplicate analysis consisted of paired measurements of 26 gamma-emitting nuclides, H-3, Sr-89, Sr-90, low levels I-131 and gross beta. A dual level criteria for agreement was established. If the paired measurements fall within i 15 percent of their average value, then agreement between the measurements has been met. If the value falls outside of the i 15 percent, then a two standard deviation range (95 percent confidence level) is established for each of the analyses. If the ranges overlap, agreement is obtained. Table 4.4 shows that 1300 paired duplicate measurements were analyzed for 1993. A total of 99.77 percent of all measurements fell within the established criteria discussed above. Two water samples did not meet the gamma analysis criteria. 61
