I Exscutiva Summary The Radiological Environmental Monitoring Program for Seabrook Station operated with several unplanned interruptions for the period of January through December 1998. Samples collected as part of the radiological environmental program , included air particulates, charcoal filters, milk, ground water, surface ! (sea) water, sediment, fish, lobsters, shellfish, vegetation 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. I During 1998, Seabrook Station had a unit capacity factor of 82.74. This capacity factor takes into account four forced outages during the year. The first forced outage was a continuation from 1997 and accounted for 16.39 days in 1998. The remaining forced outages encompassed 30, 12.14 and 2.46 days respectively. In 1998, the maximum whole body dose to the hypothetically exposed individual was .0197 millirem. This whole body i dose is the sum of all the exposure pathways for liquid and gaseous effluents, plus the direct whole body dose from station operations. This i total dose represents approximately 0.08% of the whole body dose limit for l a member of the public as set forth in 40CFR190. The complete calculational methodology is submitted to the NRC as part of the Annual Radioactive Effluent Release Report. l 11 4

g ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 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 following specific objectives: To provide an indication of the appearance or accumulation of any radioactive material in the environment caused by the operation of the nuclear power station. To provide assurance to regulatory agencies and the public that the station's environmental impact is known and within anticipated limits. To verify the adequacy and proper functioning of station effluent controls and monitoring systems. 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 Service Corporation collected the terrestrial samples. Normandeau Associates, Inc. collected the marine and sediment samples. After initial processing,.the samples were sent to the Duke Engineering & Services Laboratory (DESL) in Westboro, Massachusetts for further processing and radionuclide analysis. The DESL also processed the environmental thermoluminescent dosimeters- (TLD's) . This report is a summary of the findings of the Radiological Environmental Monitoring Program for 1998. It is being provided in compliance with plant Technical Specification 6.8.1.3. 1 1 1

3.0 Summary of Radiological Environmental Data The following pages summarize the analytical results of the environmental samples, which were collected in 1998. Each environmental media category is presented as a separate subsection. A table that summarizes the data follows a discussion of the mampling requirements and results for each program. Listed at the top of each table are 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 that exceed ten times the yearly average of control measurements. The latter are classified as "non- routine" measurements. The next column lists the Lower Limit of Detection (LLD) for those radionuclides which have detection capability requirements specified in the Off-Site Dose calculation Manual. Those sangling stations which are adjacent to the plant and which could conceivably be 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 outer ring (emergency response) stations.
A set of statistical parameters is calculated for each radionuclide. This set of statistical parameters includes separate analyses for (1) the indicator stations, (2) the station having the highest annual mean concentration for that radionuclide, (3) and control stations. For each of these three groups of data, these parameters are as follows: The mean value of all concentrations.
- The range of values.
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 1998. 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 collection). The radionuclide value concentrations (charcoal media) have been corrected for radioactive decay to the end of the collection. The airborne radiolodine (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 reported as "not detected". These values are set to zero for averaging purposes. Where a range of values is reported in the tables of this section, values less than the a posteriori LLD for the analysis are reported as zero. 13 J
l 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 I the 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 j (indicated as GR-B in tables) to allow for the decay of radon daughter 4 products. For the year, 415 particulate filters were collected for gross beta activity. A particulate filter from station #5 during week #10 was not sampled due to very low sample volume. This was due to an unintentional cut off of pcwer to the sampler. Quarterly composite air filters from each location were analyzed for gamma emitting radionuclides. In 1998, naturally occurring Be-7 was the j only nuclide detected. All gross beta samples were collected as 4 required. 1 I i i { i i 14

B) Charcoal Filters charcoal filter cartridges are in series with the air particulate glass-fiber filters. Monitoring stations were established at a total of eight locations (five are required by the ODCM). Seven of these are l indicators and one is a control. Charcoal filters from the air sampling l stations were collected and analyzed weekly for I-131 activity. During 1998, A total of 414 charcoal cartridges from all eight locations were analyzed. For the year, 415 particulate filters were collected for gross beta activity. A particuli.te filter from station #5 during week
#10 was not sampled due to very low sample volume. This was due to an unintentional cut off of power to the sampler. A charcoal filter cartridge for sampler #8 was inadvertently not replaced for sample week
#35. No I-131 activity was detected.

e 1 l l . l j C) Milk Milk samples were collected every two weeks during the pasture season i and monthly at other times. Samples are analyzed for I-131 and l gamma-emitting radionuclides. , 1 Detectable concentrations of Cs-137 were measured in several samples collected in 1998. Five positive results for Cs-137 were detected at required locations TM-04 (3), TM-09 (1), and TM-15 (1). Additional locations TM-16 (8) and TM-21 (1) also had positive Cs-137 results. 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 1998 are consistent with that detected in the. pre-operational phase. l l Potassium-40 is a naturally occurring nuclide detected in the milk samples. 24

E) Ground Wstar There is no requirement to collect ground water samples. Ground Water samples are obtained from two locations on a quarterly basis, and are ; analyzed for gross-beta activity, gansna-emitters and tritium. Gross i beta activity was detected in all samples taken and is due to naturally occurring radium and its daughter products. l l l l 1

L) Direct Radiation Direct gamma radiation exposure was measured with thermoluminescent dosimeters (TLDs). Two TLD badges are placed at each of the monitoring stations (Each TLD badge has 3 CaSO 4 :Tm elements) . A total of forty-seven stations are located offsite, forty of which are required. All badges were collected and readout on a quarterly schedule. All exposure rates were normalized to a 91-day quarter. A swmmary of the data is l- shown in Table 3.1. Indicator location results are statistically ~ identical to control locations. In the second quarter, TLD badge #34 located in Exeter, NH was J inadvertently destroyed when the local Phone company removed the utility 1 pole for replacement. All other results are consistent with previous preoperational and operational data. j l 1 i 1 i 1 l 57 i

4.0 Quality Assurance Program The quality assurance program at the Duke Engineering & Services Environmental Laboratory is designed to serve two overall purposes:
- 1) Establish a level of confidence in the measurement process to assure the licensee, regulatory agencies and the public that analytical results are accurate and precise; and 2) Identify deficiencies in the sampling or the measurement process to those responsible for these operations so that corrective actions can be taken. Quality assurance is applied to all steps of the measurement process, including the collection, reduction, evaluation and the reporting of data, as well as the record keeping of the final results. Quality control, as part of the quality assurance program, provides a means to control and measure the characteristics of measurement equipment and processes, relative to established requirements.
The DESEL employs a comprehensive program to monitor the quality of analytical processing to ensure reliable environmental monitoring data. The program includes the use of approved and controlled procedures for all work activities, a nonconformance and corrective action tracking program, systematic internal audits, audits by external groups, a laboratory quality control program, and a staff training and retraining program. Monitoring programs include the Intralaboratory Quality control Program administered by the Laboratory QA of ficer (used in conjunction with National Institute Standards and Technology's Measurement Assurance Program, NIST MAP) and the third party interlaboratory programs administered by the US EPA and Analytics, Inc. These prograns are targeted to supply QC\QA sources at 5% of the routine sample analysis load. In addition, the Laboratory Quality Control Audit Committee conducts a blind duplicate quality assurance program. Environmental TLD Program The Panasonic environmental dosimeters are processed by the DESEL, which is a National Voluntary Laboratory Accreditation Program (NVLAP) certified laboratory. The NVLAP is conducted through the Battelle Pacific Northwest Laboratories. The DESEL environmental TLD program has its own quality assurance program, through the Laboratory Quality Assurance Officer, as well as the NVLAP program. Under these programs, dosimeters are irradiated to ANSI specified testing criteria and submitted for processing to the Dosimetry Services Group as " unknowns". The bias and precision of TLD processing is measured against this standard and is used to indicate trends and changes in performance. Instrument checks, although routinely performed by the Dosimetry Services Group and representing between 5-10% of the TLD's processed, are not part of this report because they do not represent a true process check sample since the doses are known. The DESEL processed 3576 environmental TLD's in 1998. Ninety-six independent performance tests were conducted (2.7% QC). of these, 72 TLD's were submitted to the Dosimetry Services Group and 24 were submitted to the Battelle Pacific Northwest Laboratories testing program. All (100%), met the acceptance criteria for accuracy and precision with an average bias during the first half of 1998 of -0.1 +/- 2.5% and -1.9 +/- 3.3% for the second half of 1998. During 1998, a study was conducted to evaluate dosimeter mean bias response as a function of depth and dose level. The process was standardized by 'binning' dose levels into 100 mR increments starting with 0 mR out to 400 mR for high-energy irradiation (NVLAB Cat.IV). The percent bias was 0.81, 0.83 and -2.8 at dose levels of 0 - 100mR, >100-200mR & >300-400mR,respectively. 78
Intralaboratory Quality Control Program The DESEL conducts an extensive 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 iked samples. Process check samples are either samples submitted .uplicate to evaluate the precision of the measurement or spikou with a known quantity of radioactive material to assess the bias in the measurement. The records of the quality control program are reviewed by the c Laboratory QA Officer. Corrective measures are taken whenever applicable. A summary of the program process check results are found in Table 4.1. Two low-level iodine-131 results fell outside the laboratories acceptance criteria for bias and precision and one gamma result fell outside the laboratories criteria for bias, however since the mean bias for this set was within +/- 15% no further action was required. Two low-level iodine-131 in milk results fell outside the acceptance criteria for bias and precision. DESL confirmed the iodine activity by gamma analysis to be within 5% of the mean. A Condition Report (CR) CR98-009 was issued in December 1998, following the second failure (10/98). Third Party Intercomparison Program The DESEL also participates in two independent third party Intercomparison programs. At the end of 1995, the US EPA ended its Environmental Intercomparison Studies Program. To replace this mix of radionuclides and matrices, the DESEL now participates in two third party progranm; the US EPA Performance Evaluation (PE) Study for radionuclides in water and the Analytics Inc.'s Environmental Cross check Program for radionuclides in milk, water and on air filters. 1998 is the last year the EPA will provide PE samples for analysis. The overall scope of the Analytics program was designed to be comparable to the pre-1996 EPA program and reflects the mix of client REMP media processed by DESEL. Each sample supplied by the EPA or Analytics is analyzed in triplicate and the results are returned to the EPA or Analytics within a specified time frame. When the known values are returned to the Laboratory, the results are evaluated against specific Laboratory acceptance criteria and the EPA results are evaluated against EPA control limits. When results of the cross check analysis fall outside of the acceptance criteria or control limit, an investigation is initiated to determine the cause and, if appropriate, corrective measures are taken. EPA PE Program: During 1998,the DESEL analyzed 13 sample sets, representing 34 nuclides. The analysis included gamma emitters, gross alpha, gross beta, strontium-89&90, low-level iodine-131, tritium, radium-226 and 228 and natural uranium. Table 4.2 provides a summary of results for 1998. One set of EPA gross alpha analysis (ref date 1/30/98) fell outside the EPA control limits. The DESEL performed an investigation (Inquiry 3-98) to address the failure of the gross alpha samples. DESEL mean value: 9.8 pCi/L EPA known value: 30.50 +/- 7.60 pCi/L EPA control limits: 17.3-43.70 pCi/L The DESEL had previously determined the root cause of the low bias in gross alpha analysis to be sample evaporation and the amount of solids present in the sample. Follow up analysis of the EPA samples (EL 189-98) produced results within +6.6% and +5.9% of the known value with and 79
without celta rsep;ctivaly. In addition, DESEL procasosd a b:ckup sample from the 1/30/98 EPA PE sample. The results are DESEL mean values 17.95 pCi/L EPA known value 30.50 +/- 7.60 pC1/L EPA control limits: 17.30 - 43.70 pCi/L i 1 The Laboratory Quality Control Audit Committee (LQCAC) determined that no further action was necessary. ANALYTICS Program: 14 sets in water, milk, and air filter matrices were analyzed for as part of Analytics Cross Check Program. This analyses included gamma emitting nuclides, gross alpha, gross beta, strontium 89 and 90, low level iodine -131, tritium, radium-226 and 228, Plutonium 238 and 239, and uranium 234 and 238. Table 4.3 provides a summary of the results for 1998. All DESEL mean value results met the acceptance criteria for bias, however, two low level lodine 131 results with the following precision- 14.4% for milk and 16.8% for water contributed to the change of Inquiry 6-98 (investigation) to CR 98-009. l l During the preparation of this report, known values for the last three months of 1998 have not been returned to the Laboratory from either Analytics or the EPA. These data, when available, will be submitted as part of the 1999 submittal. Blind Duplicate Quality Assurance Progrant The Laboratory Quality Assurance Audit committee (LQCAC) is comprised of one member from each sponsor company that are serviced by the Duke Engineering and Services Environmental Laboratory. Two of the primary functions of the LQCAC are to conduct an annual audit of laboratory operations and to coordinate the Blind Duplicate Quality Assurance Program. Under the Blind Duplicate Quality Assurance Program, paired samples are submitted from the five plants, including the Seabrook Nuclear Power Station. They are prepared from homogeneous environmental media from each respective plant, and are sent to the Laboratory for analysis. The samples are ' blind' in that the identification of the matching sample is not identified to the Laboratory. The LOCAC analyzes the results of the paired analyses to evaluate precision in laboratory measurements. A total of 57 paired samples (Table 4.4) were submitted by the five DESEL sponsor company plants for analysis during 1998. The database used for the duplicate analysis consisted of paired measurements of 25 gamma-emitting nuclides, H-3, Sr-89, Sr-90, I-131 and gross beta. All measurements were evaluated, whether the results were considered statistically positive or not, and whether the net concentration was positive or negative. Of the 1492 paired duplicate measurements evaluated in 1998, 1486 (99.6%) fell within the established acceptance criteria. The total number of sample measurements completed as part of this program are listed in Table 4.5 80
