Executive Summary The Radiological Environmental Monitoring Program (REMP) for Seabrook Station operated successfully for the period of January through December 2004. This report describes the REMP and its implementation as required by Technical Specifications and defined in the Offsite Dose Calculation Manual (ODCM). It also contains analytical results, data evaluation, dose assessment, and data trends for each environmental sample media. Also included are the results of the Land Use Census, historical data, and the AREVA Environmental Laboratory performance in the Quality Assurance Intercomparison Program required by the ODCM. Samples collected as part of the radiological environmental program included air particulates, charcoal filters, milk, ground water, surface (sea) water, sediment, fish, lobsters, shellfish, algae, terrestrial food products, broad leaf vegetation and direct radiation. Radiological analysis on each sample media included determination for both gamma andlor beta radiation. Any variability observed in the data is based on natural variables that can influence background radiation. The radionuclides identified as naturally occurring are K-40, Be-7, Th-232 and its daughter products. The levels detected are similar to those levels measured during the pre-operational phase of the monitoring program. Condition reports relating to the REMP were entered into the Station Corrective Action Program. In 2004, the maximum whole body dose to the hypothetically exposed individual was 0.0261 millirem. This whole body dose is the sum of all the exposure pathways for !iquid and gaseous effluents, plus the directwhole body dose from station operations. This total dose represents approximately 0.10% of the whole body dose limit for a member of the public as set forth in 4OCFR190. The complete calculational methodology is submitted to the NRC as part of the Annual Radioactive Effluent Release Report. The results of the 2004 Radiological Environmental Surveillance Program continues to clearly demonstrate that there is no significant short term or chronic long-term radiological impact on the environment in the vicinity of Seabrook Station from plant operations. No abnormal radiological characteristics were identified or observed in the surrounding environs. Plant effluents contribute no measurable radiation exposure to the general public as confirmed and assessed by the REMP. Environmental radiation levels measured at the site boundary and near the nearest resident are at background levels. This is consistent with previous data. As a result, no increasing or decreasing trends were identified. iv

ANNUAL RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 1.0 Introduction FPL Energy's Radiological Environmental Monitoring Program (REMP) 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.
FPL Energy collected the terrestrial samples. Normandeau Associates, Inc. collected the marine and sediment samples. After initial processing, the samples were sent to the Framatome Environmental Laboratory in Marlborough, Massachusetts for further processing and radionuclide analysis. Framatome also processed the environmental thermoluminescent dosimeters (TLD's). This report is a summary of the findings of the Radiological Environmental Monitoring Program for 2004. It is being provided in compliance with Part A of Seabrook Stations Offsite Dose Calculation Manual (ODCM) and Technical Specification 6.8.1.3. r.5: o;,.j y 2.0 Environmental Monitoring Program Table 2.1 outlines the monitoring program as specified in the Seabrook Station ODCM, Part B, Section 4. Table 2.2 lists the operational sampling stations and their specific locations (distances are measured from the center of the Unit 1 Containment Building). The sampling locations are shown on maps in Figures 2.1 through 2.6. The sampling and analysis program as described above fulfills the minimum requirements for environmental sample collection and analysis as contained in the ODCM Table A.9.1-1, and includes additional sampling of various pathways and locations beyond the minimum.

L r' 3.0 Summary of Radiological Environmental Data The following pages summarize the analytical results of the environmental samples, which were collected in 2004. Each environmental media category is presented as a separate subsection. A table that summarizes the data follows a discussion of the sampling requirements and results for each media type. 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 the required reporting level as documented in Table A.9.1-3 of the ODCM. The latter are classified as "non- routine" measurements. The next column lists the Lower Limit of Detection (LLD) for those radionuclides that have detection capability requirements specified in the ODCM. Those sampling 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 potential 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 3 times the standard deviation for that measurement) divided by the total number of measurements.
Each single radioactivity measurement in media 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 2004. 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 radioiodine (charcoal) concentrations have been calculated assuming a constant flow rate and concentration throughout the collection period and corrected for decay while sampling as well as between sample collection termination and analysis. 3.1 Air Particulate Air monitoring stations were established at a total of eight locations (Five are required by the Offsite Dose Calculation Manual). Seven of 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. In 2004, these filters were collected either weekly or bi-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. The change from a standard weekly to a biweekly filter change out cycle was initiated for all air particulate stations as a result of equipment / procedure upgrades that were designed to reduce potential system down time due to equipment failure. Continuous automated remote monitoring of vital system parameters is performed with telemetry that detects power outage, pump failure, filter degradation, tubing failures and excessive filter loading. The telemetry communicates by cellular transmission to a web server that communicates to a shift technician's pager when set-point thresholds are reached, providing 2417 alert notification. This capability provides for timely identification of problems and corrective actions that reduce the potential loss of air sampling. The following list indicates when the change from weekly to biweekly filter change-outs occurred for each sampling station: Air Particulate Station Date After Which Biweekly Implemented AP/CF-01 05/05/04 AP/CF-02 05/05/04 AP/CF-03 05/05/04 AP/CF-04 05/05/04 AP/CF-05 02/25/04 AP/CF-06 (Replaced by AP-09 on 02/04/04) AP/CF-07 03/10/04 APICF-08 02/25/04 APICF-09 05/05/04 As noted in the list above, the air sampling station at the Georgetown Electric Company Substation (AP/CF-06, Control) was relocated about one mile (same sector) to a new location (designated APICF-09, Control) to improve technician safety working conditions. For the year, 274 particulate filters were collected for gross beta activity. The gross beta activity for the indicator locations is statistically equivalent to that seen at the control station. The gross beta results for all stations are also similar to what was seen in the pre-operational program and for the last fourteen years of commercial operation. Fluctuations seen in the gross beta activity throughout the year can be attributed to changes in the environment. Natural environmental processes such as wind direction, precipitation, snow cover, and soil temperature and moisture affect concentrations of naturally occurring radionuclides in the atmosphere directly above land. No plant related gamma-emitting radionuclides were detected in any of the quarterly composite air filter samples analyzed. Therefore no increasing or decreasing trends were observed. In 2004, naturally occurring Be-7 was the only nuclide detected. Be-7 is of cosmogenic origin. This is consistent with previous years both pre- and post-operationally. The air particulate sampling program demonstrated no off-site dose to the public or impact to the environment, from this pathway, as the result of plant operations. This is consistent with previous years and the pre-operational program. Air particulate sample collection and analysis deviations from the ODCM required program are described in Section 4.

' 7'-: v'.. 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 indicators and one is a control. Charcoal filters from the air sampling stations were collected and analyzed for 1-131 activity to a idwer limit of detection (LLD) of 0.07 pCi/M 3. During 2004, a total of 274 charcoal cartridges from eight locations were analyzed. As described for the air particulate samplers (see Section 3.1), the collection cycles for the charcoal filters was extended from weekly to biweekly during 2004. An iodine decay analysis compared a 1-week vs. 2-week air sampling cycle and the ability to detect iodine. For the assumption of chronic air concentrations of 1-131, the longer collection time results in a higher total deposition of 1-131 that remains on the cartridge at counting time and, therefore, an MDA (Minimum Detectable Activity) equal to or better than the 1-week cycle. For potential short duration releases of 1-131, a modest increase insampler flow rate (to approximately 1.8 SCFM) provides for a higher iodine collection factor per unit time. This higher collection factor compensates for the decay losses due to the longer turn-around time with a 2-week change-out cycle such that the effective detection capability remains about the same. No sample analysis indicated a detectable measurement for 1-131 that was statistically relevant (positive) at the air sampling locations stated in the ODCM. The REMP program has detected no radioiodine at any offsite air sample location, since Seabrook Station's initial criticality of June 1989. The pre-operational data for 1-131 are consistent with present data. The estimated organ doses from iodine in gaseous effluents are well below the I OCFR50, Appendix I dose criteria for the reporting period. Therefore, no increasing or decreasing trends were observed. Charcoal filter sample collection and analysis deviations from the ODCM required program are described in Section 4.

3.3 Milk * ( a,,
) .. air A : 'i nt Milk samples were collected semi-monthly duiring.the pasture season and monthly at other times.
Samples are analyzed for l-131 and gamma emitting radionuclides. The ODCM (Table A.9.1-1) requires that milk samples be collected from three locations within 5 km of the plant having the highest dose potential. If there are none, then one sample from milking animals in each of three areas 66ween 5 to 8 km distant where the doses are calculated to be greater than 1 mrem/yr. At the end of 2003, one of the farms in the sample collection area (TM-16) was relocated and became unavailable-as-a REMP milk sampling site. No milk samples from TM-16 were collected in 2004. Due to the limited inventory of milk animals in the site area, as reconfirmed by the 2004 Land Use Census, no suitable substitute location was available to replace the lost sample site bringing the number of available sample locations to less than the number required by the ODCM sampling program (no available milk within 5 km, and only two milk location between 5 and 8 km). The ODCM allows for broad leaf vegetation samples to be collected if milk sampling is not performed in accordance to the REMP requirements. As a result, two new site boundary and one control vegetation collection locations were added to the REMP in 2004 to compensate for the limited milk sampling (see Section 3.12). A total of 72 milk samples were collected within the year from available locations. Each sample was analyzed for gamma emitting radionuclides. In addition, all samples were evaluated for 1-131 through an iodine extraction process. Gamma analysis indicated only potassium-40 was present. No detectable concentrations of Cs-137 were measured in any sample collected in 2004, as was the case in previous years. Past detection of Cs-1 37 is attributed to atmospheric nuclear weapons testing that persist in the environment based on similar measurements during the pre-operational period of the REMP. Figures 3.3 , 3.3.1, 3.4, and 3.4.1 illustrate the analysis results for Cs-1 37 in milk over the current year (2004) and previous years of the REMP. Potassium-40 was detected in all indicator and control locations. Potassium-40 is a naturally occurring nuclide detected in many environmental sample media. Iodine-131 was not positively identified at any location for the year. The samples met the Lower Limit of Detection (LLD) requirements (1 pCikg) for 1-131 in milk. This is consistent with previous years for both the pre-operational and operational phases of the program. The calculated dose as the result of plant effluents is not evaluated due to the fact that no plant related radionuclides were detected. The milk-sampling program demonstrated that there is no impact to the public or environment, through this pathway, from plant operations. Therefore, no increasing or decreasing trends were observed. Milk sample collection and analysis deviations from the ODCM required program are described in Section 4. FIGURE 3.3 CESIUM-i137 IN MILK SEABROOK STATION 30-25 - 20:- 15:-

3.4 Surface AtiRc .si.' Surface water (seawater) grab samples are required at two locations (control and indicator) monthly. The indicator (01) is over the vicinity of the plant discharge. The control location (51) is located in Ipswich Bay, MA. A gamma analysis is performed on each sample. A tritium analysis is performed on the quarterly c6mpnosit6 of these samples. Forthe year, 24-gamma analyses were performed on surface water samples. The only radionuclide detected in 2004 was naturally occurring K-40. No plant related nuclides were detected. The present data for gamma emitters in seawater is consistent with that of the pre-operational program and previous years of operations. Therefore, no increasing or decreasing trends were observed. ., Quarterly composites from the same gamma collection samples were analyzed for tritium. Eight samples were analyzed in 2004. The monthly composites showed no presence of tritium. The composites met the required LE'D (3000 pCi/kg) for tritium in seawater. These results are consistent with pre-operational tritium data. -The calculated dose, as the result of plant effluents is not evaluated due to the fact that no plant related radionuclides were or have been detected. Therefore, no increasing or decreasing trends in dose were observed.

For the year, four quarterly ground water samples were collected from two locations. These samples were analyzed for gross-beta activity, gamma-emitters and tritium. These samples were collected from the drinking water line supplied to the Site (by the Town of Seabrook) and from an inactive well located approximately 1 km North of the plant. Gross beta activity detected in all eight samples taken is due to naturally occurring radium and its daughter products. The gross beta activity seen at both locations is similar to what was seen in the pre-operational program and is consistent with results from previous years of commercial operations. Figures 3.5 and 3.5.1 indicate the current year (2004) and the long-term measurement history for gross beta in well waters. No tritium or gamma emitters were detected. The calculated dose is not evaluated due to the fact that plant related radionuclides have not been detected. Therefore no increasing or decreasing trends were observed. There is no impact to the public, through this pathway, from plant operations. Any sample collection and analysis deviations from the ODCM required program, or reportable concentrations, that may have occurred during the year are described in Section 4.

" Semiannual sediment sampling is required at one.,indicator location, although a total of five locations, three indicators-'n'd-tw confrols are collected. The indicator stations are comprised of two beach sediment cores from Seabrook Beach and one sub tidal sediment core taken from near the discharge structure. Th6'cbontrol locations, both beach and sub tidal, are located within Ipswich Harbor. A total of 30 samples Were6c'lleef6d for the year from all locations. Each sediment core was sectioned into 5-centimeter~segmeriti." Segment 1 extends from the top of the core to 5 centimeters, segment two extends from 5 to 10 centimeters and the third segment extends from 10 to 15 centimeters in depth. A gamma analysis was performed on each segment. The only radionuclides detected in 2004 were naturally occurring K-40 and Th-232 with its natural daughters. Potassium-40 w~as detected in all core samples at all depths from all locations. Thorium-232 (as measured'iri the gamma isotopic analysis as AcTh-228) and its daughters were also present in all samples at all locations. No plant related radionuclides were detected in any segment. No increasing or decreasing trends were observed. This is consistent with the pre-operational program and with previous years of plant operations. There is no dose to the public or impact to the environment from any pathways associated with this media. Any sample collection and analysis deviations from the ODCM required program, or reportable concentrations, that may have occurred during the year are described in Section 4.

3.7 Fish Semiannual fish and invertebrate samples are required from two locations. The Program calls for samples to be collected semiannually, or in season, from two locations. Quarterly collections are attempted to cover the sampling requirements. This section presents the results for fish sampling only. Invertebrate results may be found in Sections 3.8 and 3.9, entitled Lobsters and Shellfish, respectively. During the year, the fish species available from Station FH-03 (indicator station) and Station FH-53 (control station) was Winter Flounder. Fish were not collected in the first quarter 2004 due to their unavailability. The first quarter sampling attempt is above the minimum sampling requirements of the program, and as such the inability to collect samples is not considered a deviation in the REMP. A gamma analysis was performed on each sample collected. In 2004, the only radionuclide detected in fish samples was naturally occurring K-40. No plant related radionuclides were detected. No increasing or decreasing trends were observed. Subsequently, there is no dose to the public or impact to the environment, through this pathway, from plant operations. This is consistent with previous years of plant operations, as well as the pre-operational program. Any sample collection and analysis deviations from the ODCM required program, or reportable concentrations, that may have occurred during the year are described in Section 4.

3.9 Shellfish Semiannual fish and invertebrate samples are required from two locations. This section provides the results for shellfish samples only. Fish and other invertebrate results may be found in the Sections 3.7 and 3.8, entitled Fish and Lobsters, respectively. During the year there were two species of mussels harvested for analysis. Modiolus (horse mussels) were collected, by divers, from near the discharge outfall (indicator station) and from Ipswich Bay (control). Mytilus (blue mussels) were collected from the intratidal areas of Seabrook Harbor (indicator) and Plum Island, MA (control). Eight samples were collected for 2004 and analyzed for radioactivity in the edible portion or meat of the shellfish. The analyses included both gamma isotopic and Strontium 89 and 90 determinations. In the first collection series of the year (May), mussel shells were also analyzed for Strontium 89 and 90 (four samples) to see if there isany indication of strontium uptake into the shell. This is considered a one time special assessment outside the minimum requirements of the REMP. The only radionuclide detected in shellfish samples (either edible portion or shell) in 2004 was naturally occurring K-40. No plant related gamma emitting radionuclides or strontium was detected. Therefore, no increasing or decreasing trends were observed. Subsequently, there is no dose to the public or impact to the environment, from this pathway, from plant operations. This isconsistent with the pre-operational program and with previous years of plant operations. Any sample collection and analysis deviations from the ODCM required program, or reportable concentrations, that may have occurred during the year are described in Section 4.

3.10 Irish Moss yr;:'- ',vt'; . There is no REMP requdiemnrit tocollect Irish Moss (algae) samples. Semiannual Chondrus (Irish Moss) samples were collected from an indicator area near plant discharge and a control location within Ipswich Bay. .f plant related radionuclides were re-concentrating in the aquatic environment, an early indication of this may be shown in this type of environmental species. Four samples (two indicator and two-control) were collected for the year. A gamma analysis was performed on each sample; Naturally occurring Potassium 40 was detected in all samples for both indicator and control stations. Beryillium-7 was also detected in one sample from the control site indicating that it is from natural cosmogenic origin. No plant related radionuclides were detected. Therefore, no increasing or decreasing trends were observed. Subsequently, there is no dose to the public or impact to the environment, through this pathway, from plant operations. This is consistent with the pre-operational program and with previous years of plant operations.

There is no requirement for food crop samples as long as the required milk locations are available. As noted in Section 3.3, milk sampling the minimum required locations in 2004 was not possible due to the limited inventory of milk animal locations in the site vicinity. To compensate for this, new vegetation sample locations at the site boundary were added to the REMP in 2004. Section 3.12 describes the alternate broad leafy vegetation collections. In addition to the new broad leafy vegetation sampling, nine food crop samples were collected from three locations during the growing season months (June, July and August). These includes Strawberries (June), green beans, blueberries and tomatoes (July), and corn (August) samples. For the year, a total of nine food crop samples were collected. Samples were analyzed for gamma-emitting radionuclides. The only radionuclide detected in 2004 was naturally occurring K-40. Potassium 40 was detected at both indicator and control stations sampled. No plant related radionuclides were detected. Therefore, no increasing or decreasing trends are identified. Subsequently, there is no dose to the public or impact on the environment, through this pathway, from plant operations. This is consistent with the pre-operational program and with previous years of plant operations.

3.12 Vgtto vvA\ v: ^tf; ..- : { ¶rs ,>. -vi-'.,#.' In lieu of milk sampling, t,4e.ODCM, Table A.9.1-1, requires broad leafy vegetation samples grown nearest of two different offsite locitions 'witht'he highest D/0, and one control location 15-30 km distant in the least prevalent wind direction, be collected when available (growing season). Offsite locations are defined in the tJFSARas a minimum, the land within a 3000-foot radius of the two reactor building centerlines. -The analysis of garden locations in the Land Use Census provides a ranking of potential sampling sites for use in determining sampling locations in the general ' population. Since sampling of three different types of broad leaf garden vegetables is not feasible due to uncertain availability, other types of broad leafy vegetation were 'utilized. Two locations at the site boundary with a maximum D/Q were selected over ranked D/Q gardens in the general population. These two locations in areas with available sample media and are on FPL Energy property. A third far field control location was selected in Georgetown, MA. Sampling tree leaves as broad leaf vegetation at the selected locations provide increased reliability for sample availability. For 2004, monthly (growing season, May through October) broad leaf vegetation samples from the three sites were collected and analyzed. Samples are analyzed for Iodine-131 and gamma-emiting radionuclides. The only radionuclides detected in 2004 were naturally occurring K-40 and Be-7. Potassium-40 was detected at both indicator and control locations for all samples. Beryllium-7 was detected in all but one sample collected, and is attributed to natural cosmogenic origins. No plant related radionuclides were detected.. Assuming that the results of broad leaf vegetation sampling are comparable to broad leaf food products, there is no detectable dose to the public or impact on the environment through this type pathway from plant operations. Any sample collection and analysis deviations from the ODCM required program, or reportable concentrations, that may have occurred during the year are described in Section 4.

. e-4-e' a A 3.13 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 location result is an average of six independent readings per quarter. A total of forty-seven stations are located offsite, forty of which are required. The badges were collected and readout on a quarterly schedule. The exposure rates were normalized to a 91-day quarter. A summary of the data is shown in Table 3.1. Overall, the REMP direct radiation program showed no indication of increased direct radiation above background either within the owner-controlled area or beyond the site boundary. This is demonstrated by the fact that indicator location results are statistically identical to control locations. The 2004 annual mean of all indicator !ocations was 16.0 mR/91-day quarter while the mean of all control locations was 17.2 mR/91-day quarter. This verifies that there is no difference in the annual dose as a function of distance from the plant The fractional difference of the 2004 TLD measurements compared with pre-operational TLD measurements show that no direct dose was attributed to station operation during 2004. The direct radiation-monitoring program demonstrated that there was no offsite dose to the public or impact to the environment from the operation of the plant. Therefore, no increasing or decreasing trends were detected. Any sample collection and analysis deviations from the ODCM required program, or reportable concentrations, that may have occurred during the year are described in Section 4.

Table A.9.1-1 of the Offsite Dose Calculation Manual (ODCM) allows for deviations in the REMP sampling schedule "if specimens are unobtainable due to circumstances such as hazardous conditions, seasonal -unavailability and malfunction of automatic sampling equipment." All deviations from the sampling schedule shall be documented each year in the Radiological Environmental Operating Report. The deviations for 2004 are as follows:
- It was determined in January that milk from TM- 6 (no January monthly milk could be collected at TM-16 as required) would no longer be available to the REMP due to loss of milk animals. The latest Land Use Census indicates that there is not a sufficient remaining inventory of potential milk producing locations to satisfy REMP. requirements. Alternate board leaf vegetation sampling is selected to provide substitute samples during the growing season.
- Air sample station AP/CF-08 lost power for approximately 72 hours (01/23/2004 to 02/08/2004) due to GFI breaker trip and therefore failed to continuously collect a sample. It is also noted that AP/CF-08 is not one of the required REMP sampling locations and is reported here for information only.
* -Air sample station AP/CF-03 was found not running at time of change out on 02/25/2004 due to a blown pump motor fuse and therefore failed to continuously collect a sample. Approximately 53 hours of run time were lost.
- Collection of fish samples off shore was not accomplished as scheduled in the first quarter, 2004, due to unavailability of fish. It should be noted that fish collection is only required semiannually or when fish species are in season., The inability to collect fish in the first quarter is not considered a deviation from the required REMP, but is included here for information only.
- Air sample station AP/CF-08 lost AC power for approximately 2 hours on 04/08/2004 due to utility maintenance activities not related to the air sampler, thereby failing to continuously collect a sample. This situation was identified by a remote telemetry alert notification which helped to prevent an extended loss of sample. It is also noted that AP/CF-08 is not one of the required REMP sampling locations and is reported here for information only.
- Air sample station AP/CF-05 lost air flow for approximately 2 hours 14 minutes on 05/21/2004 due to broken inlet poly tube, thereby failing to continuously collect a sample. This situation was identified by a remote telemetry alert notification for low pump vacuum that helped to prevent an extended loss of sample.
- Air sample station AP/CF-01 lost power for approximately 15 hours on 09/28/2004 due to a blown pump fuse, and therefore failed to continuously collect a sample. This situation was identified by a remote telemetry alert notification for low pump vacuum that helped to prevent an extended loss of sample.
- Third quarter, 2004, seawater composite sample for Station WS-51, Ipswich Bay (Control), did not contain the September seawater grab sample as required due to it being accidentally discarded at the environmental laboratory after its g-iorma analysis wvas performed. Additional laboratory staff and management oversight has been implemented to prevent reoccurrence.
4.2 Comparison Of Achieved LLDs With Requirements Table A.9.1-2 of the ODCM indicates the required Lower Limits of Detection (LLDs) for environmental sample analyses. (This table is duplicated in Table 4.1 of this report.) Occasionally an LLD is not achievable due to a situation such as a low sample volume caused by sampling equipment malfunction. In such a case, ODCM Table A.9.1-2 requires a discussion of the situation in the annual Radiological Environmental Operating Report. At the Framatome Environmental Laboratory (FANPEL), the target LLD for any analysis is typically 30-40 percent of the most restrictive required LLD. Expressed differently, the typical sensitivities achieved for each analysis are at least 2.5 to 3 times greater than that required by the Seabrook ODCM. For each analysis having an LLD requirement in ODCM Table A.9.1-2, the a posteriori (after the fact) LLD, or Minimum Detectable Concentration (MDC) calculated for that analysis was compared with the required LLD. During 2004, over 1550 analyses had an LLD requirement listed in Table 4.1. The following list the number of missed LLDs in 2004: One broad leaf vegetation sample from sample location TG-09 (sample date 10/27/2004) failed to meet the required low level 1-131 analysis MDC of 60 pCi/kg due to delay at the laboratory in conducting the analysis (failure to recognize time requirements for analysis as result in change of personnel). The laboratory has taken corrective management actions to prevent reoccurrence. 4.3 Comparison of Results Against Reporting Levels Seabrook Station ODCM Section 10.1 requires the notification of the NRC by special report within 30 days of receipt from the environmental laboratory whenever a Reporting Level in Table 4.2 is exceeded. Reporting Levels are the environmental concentrations that relate to the ALARA design dose objectives of 10 CFR 50, Appendix I. It should be noted that environmental concentratons are averaged over calendar quarters for the purposes of this comparison, and that Reporting Levels apply only to measured levels of radioactivity due to plant effluents. During 2004, no Reporting Levels were exceeded. Table 4.1 , ', DETECTION CAPABILITIES FOR ENVIRONMENTAL SAMPLE ANALYSISa

tp 5.0 QUALITY ASSURANCE PROGRAM The quality assurance program at the AREVA Framatome ANP Environmental Laboratory (FANPEL) is designed to serve two overall purposes: 1) Establish a measure 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 and/or measurement process to those responsible for these operations'so that corrective action can be taken. Quality assurance is applied to all steps of the measurement process, including the collection, measurement and 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 the measurement equipment and processes, relative to established requirements. The FANPEL employs a comprehensive quality assurance program designed to monitor the quality of analytical processing to ensure reliable environmental monitoring data. The program includes the use of controlled procedures for all work activities, a nonconformance and corrective action tracking system, systematic internal audits, audits by external groups, a laboratory quality control program, and a staff training program. Monitoring programs include the Intralaboratory Quality Control Program administered by the Laboratory QA Officer (used in conjunction with the National Institute of Standards and Technology Measurement Assurance Program, NIST MAP) and a third party cross check program administered by Analytics, Inc. - Together these programs are targeted to supply QC/QA sources at 5% of the client sample analysis load. In addition a blind duplicate program is conducted through client environmental monitoring programs. This summary reports all intralaboratory and third party results received by FANPEL on or before December 31, 2004. 5.1 Intralaboratory Quality Control Program The FANPEL QA Officer administers an extensive intralaboratory quality control program in which process check samples are submitted for analysis. These samples are Ospiked' with a known amount of radioactive material and are'routinely submitted in triplicate to evaluate the bias and precision of a measurement process. Table 5.1 provides the summary of the process check results for January to December 2004. Of the 665 analyses, 99.4% passed the bias criteria and 99.1% of the 215 results evaluated for precision were acceptable. The FANPEL internal acceptance criteria are summarized at the end of Table 5.1. 5.2 Third Party Cross Check Program The FANPEL participates in a third party cross check program managed by Analytics Inc. to satisfy the requirements of the Station's Technical Specification and ODCM. The FANPEL Analytics program was originally used to augment the EPA Intercomparison Program that it now replaces. The current program is designed to be comparable to the pre-1996 EPA PE Program in terms of the number of samples, matrices and nuclides. The results for the 4t quarter 2003 through the 3r quarter 2004 are summarized in Table 5.2. Each sample is normally analyzed in triplicate and the results are evaluated against the internal acceptance criteria described in the FANPEL Manual 100-Laboratory Quality Assurance Plan. This acceptance protocol is used for all interlaboratory programs with no pre-set acceptance criteria.
When results fall outside of the acceptance citer~a, an investigation is initiated to determine the cause of the problem and if appropriate, corrective measures are taken. The FANPEL internal acceptance criteria are summarized at the end of Table 5.1. 5.3 Blind Duplicate, Program - Under the Blind Duplicate Quality Assurance Program, samples are split from homogeneous environmental media by the client and sent to the FANPEL for analysis. They are "blind" in that the identification of the matching sample is not identified to the.Laboratory. Participating clients submitted a total of 23 paired samples' in 2004. The measurements evaluated included twenty-six gamma emitting radionuclides, H-3, Sr-89190, and gross beta. All measurements are evaluated, whether the results are statistically'positive or not, and whether the net concentration is positive or negative. The samples submitted as part of this program are listed in Table 5.3. For the 2004 program, 99.8% (486/487) of the measurements met the FANPEL internal acceptance criteria. 5.4 Environmental TLD Quality Assurance Program Performance documentation of the routine processing of the Panasonic environmental TLDs (thermoluminescent dosimeter) program at the FANPEL is provided by the dosimetry quality assurance testing program. This program includes independent third party performance testing by Battelle Pacific Northwest Labs and internal performance testing conducted by the Laboratory QA Officer. Under these programs, sets of six dosimeters are irradiated to ANSI specified testing criteria and submitted for processing to the Dosimetry Services Section as "unknowns". The bias and precision of TLD processing is measured against this standard and is used to indicate trends and changes in performance. Instrumentation checks, although routinely performed by the Dosimetry Services Group and representing between 5-10% of the TLDs processed, are not presented in this report because they do not represent a true process check sample since the exposures are known to the processor. Ninety performance tests were conducted in 2004 by FANPEL and the third party tester. These tests were made on 15 separate sets of 6 dosimeters. All of the 15 TLD test sets passed the mean bias criteria of +20.1%. Of the ninety individual measurements, 100% of the dosimeter evaluations met the FANPEL Internal Acceptance Criteria for bias (+/-20.1%) and precision (+/-12.8%). Third Party QC results are summarized below. S I Perenage oi ncdividusvri na lysesho s AnsP nFi:

The 2004 census was completed in accordance with the requirements of the ODCM. In 2004, a global positioning system was used to determine locations in the off-site environs with respect to the center of the site (Unit I Containment). The nearest resident, garden and milk animal locations identified in the 2004 Land Use Census and their distances are shown in Table 6.1. The results of this census showed that the sampling locations used in 2004 have the highest calculated dose commitment. In 2004, broad leaf vegetation was added to the sample collection and analysis program due to the absence of sufficient milk producing locations to: provide REMP samples. Sampling locations for broad leaf vegetation were selected at the site boundary near points of highest predicted D/Q.
