Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 1.0 EXECUTIVE
SUMMARY
The radiological environmental monitoring program for the Yankee Atomic Electric Company's Rowe site (YR) continued for the period January through December 2005, in compliance with the Yankee Decommissioning Quality Assurance Program (YDQAP), Appendix D, Section F.2.a, and the Off-Site Dose Calculation Manual (ODCM). This annual report was prepared for the Yankee Atomic Electric Company (YAEC) by the Nuclear & Radiation Engineering Group of AREVA (Framatome ANP). Normandeau Associates performed sample collection and field preparation. Gamma exposure rate measurements and laboratory analyses were performed by AREVA Framatome ANP Environmental Laboratory (E-LAB).
Thermoluminescent dosimeters (TLDs) were used to measure direct gamma exposure in the vicinity of the site and as far away as 22.2 kilometers. Radiochemical and radiological analyses of samples were performed to detect the presence of any site-related radioactivity. Samples collected include air-particulate filters, broad leaf vegetation, fruits and vegetables, maple syrup, river water, well water, storm drain water, bottom and shoreline sediment, and fish.
In evaluating the results of those analyses it is necessary to consider the variability of natural and man-made sources of radioactivity, distribution in the environment and uptake in environmental media. This variability is dependent on many factors including site release rates, past spatial variability of radioactive fallout from nuclear weapons tests and on-going redistribution of the fallout, contribution from cosmically produced radioactivity, ground water dynamics, soil characteristics and farming practices. Any one of these factors could cause significant variations in measured levels of radioactivity. Therefore, these factors need to be considered in order to properly explain any variations in radiation detected and to distinguish between natural and station related radioactivity.
Yankee Nuclear Power Station (YNPS) was permanently shutdown in 1991. Activities at the site are now focused on fuel storage, site remediation and completion of facility decommissioning. By the end of 2005, almost all of the permanent structures had been removed. Decommissioning activities include discharging of liquids, such as ground water intrusion to building foundations, containing residual radioactivity and, for part of 2005, local area monitoring for any release of airborne radioactivity during structure demolition. All levels of radioactivity released are significantly lower than releases during plant operation. The radiological monitoring of the environment through this REMP program will continue through site decommissioning activities to assure the health and safety of the public are maintained at all times.
The predominant radioactivity detected by the monitoring program was that from non-station sources, which includes fallout from past nuclear weapons tests and naturally occurring radionuclides. As has been typical of previous years, site-related radioactivity was observed in some of the monitoring samples. The specific observations of possible site effects included Cesium-137 in bottom sediment near the former plant discharge point and tritium in ground water and storm water samples due to monitored releases. Air particulate analysis results collected in 2005 demonstrated that no site-related airborne particulate activity was present in samples collected beyond the site boundary or on site.
During 2005, there were changes made to the radiological environmental monitoring program including the elimination of food product analysis, airborne particulate analysis and the Land Use Census. These program reductions were justified based on the removal of any significant potential for an airborne source term due to the progress made in site decommissioning. Supplemental environmental air particulate monitoring in the vicinity of on-site building demolition activities was continued for part of 2005 to validate effluent release (demolition airborne dust) monitoring assumptions. Results of those analyses are included in this report (Appendix B) although they are not part of the formal REMP sampling.

Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005
2.0 INTRODUCTION
2.1 GENERAL SITE INFORMATION The Yankee Atomic Electric Company's Rowe station is located on a site of over 1800 acres in a predominantly rural area of northwestern Massachusetts, three-quarters of a mile south of the Vermont border. The site resides in the town of Rowe, Massachusetts, approximately 9 air miles east-northeast of North Adams, Massachusetts.
The surrounding area is heavily forested and lightly populated. Hills bounding the river valley rise 500 to 1000 feet above the site, reaching elevations of 2100 feet.
The Deerfield River is used extensively for hydroelectric power generation both upstream and downstream of YR. Sherman Dam, immediately adjacent to the site, operates as a hydroelectric generating station. Sherman Pond, the impoundment behind this dam, had been used as a source of cooling water for the former power plant.
The former nuclear power plant was voluntarily shut down on October 1, 1991 after 31 years of operation. The site is involved in the process of decommissioning which involves the disassembly and removal of the plant components and structures (near completion in 2005). This process is taking place in strict conformance with USNRC regulations. Oversight of the decommissioning process will also continue from the U.S. Environmental Protection Agency, the Massachusetts Department of Environmental Protection, and Massachusetts Department of Public Health.
2.2 PROGRAM DESIGN The Radiological Environmental Monitoring Program for the site was designed with specific objectives in mind. These were:
- To provide an early indication of the appearance or accumulation of any radioactive material in the environment caused by YR activities.
- To provide assurance to regulatory agencies and the public that the environmental impact from YR is known and within anticipated limits.
- To verify the adequacy and proper functioning of site 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.
These objectives will continue to be in force, to varying degrees, throughout decommissioning activities at the YR site. Due to the decommissioned status of the plant and relatively low quantities of radioactive material remaining on the site, some of the objectives have a different degree of importance than in the past.
The radiological environmental monitoring program was initiated in 1958, approximately two years before the 2
Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 plant began operation in 1960. It has been in operation continuously since that time, with improvements made periodically over those years. The program continued without modification following the shutdown of the plant in 1991 and was reduced in scope beginning in 1997, primarily to reflect the absence of short-lived radionuclides in various pathways resulting from the plant shutdown (no source of production) and the individual radionuclides short half-life (long decay time since the shutdown). As the decommissioning process nears completion, the Radiological Environmental Monitoring Program (REMP) has also been reduced to eliminate environmental media and program elements, such as air particulate monitoring, where the source term potential has been removed.
The program was designed to meet the intent of NRC Regulatory Guide 4.1, ProgramsforMonitoring Radioactivity in the Environs of Nuclear Power Plants;NRC Regulatory Guide 4.8, Environmental Technical SpecificationsforNuclear Power Plants; the NRC Branch Technical Position of November 1979 entitled, An Acceptable RadiologicalEnvironmentalMonitoringProgram;and NRC NUREG-0472, RadiologicalEffluent Technical Specificationsfor PWR's.
The environmental TLD program was designed and tested around NRC Regulatory Guide 4.13, Performance, Testing andProceduralSpecifcationsfor Thermoluminescence Dosimetry: EnvironmentalApplications. The quality assurance program was designed around the guidance given in NRC Regulatory Guide 4.15, Quality Assurancefor RadiologicalMonitoringPrograms (Normal Operations) - Effluent Streams and the Environment.
The sampling requirements of the REMP are given in Table 4-1 of the ODCM and in Table 2-1 of this report.
The identification of the required sampling locations is given in Table 4.4 of the ODCM and in Tables 2-2 and 2-3 of this report. The sampling and monitoring locations are shown graphically on the maps in Figures 2-1 through 2-6.
2.3 MONITORING ZONES The REMP is designed to allow comparison of levels of radioactivity in samples from the area possibly influenced by the site to levels found in areas not influenced by the site activities. The first area locations are called "indicators" and the second area locations are called "controls." The distinction between the two areas, depending on the type of sample or sample pathway, is based on one or more of several factors, such as site meteorological history, meteorological dispersion calculations, relative direction from the site, river flow, and distance. Analysis of survey data from the two areas aids in determining if there is a significant difference between the two areas. It can also help in differentiating between radioactivity and radiation due to site-related activities and that due to other fluctuations in the environment, such as atmospheric nuclear weapons test fallout or seasonal variations in the natural background.
2.4 PATHWAYS MONITORED For all or part of 2005, four pathway categories were monitored by the REMP. They are airborne, waterborne, ingestion and direct radiation pathways. Each of these four categories is monitored by the collection of one or more sample media, which are listed as follows, and are described in more detail in this section:

2.5 DESCRIPTION
S OF MONITORING PROGRAMS Sample types and frequency of analysis are given in Table 2-1. The sample locations are listed in Table 2-2 and Table 2-3 and shown in Figures 2-1 to 2-7. ODCM lower limits of detection (LLDs) and required reporting levels are listed in Tables 2-4 and 2-5. The program as described here includes both required samples as specified in the Off-Site Dose Calculation Manual (ODCM) and any extra samples. Following is a detailed description of the sampling program for 2005:
2.5.1 Air Particulate Sampling Continuous air samplers are installed at six locations, five of which are required by the YR ODCM. The sampling pumps at these locations operate continuously at a flow rate of approximately one cubic foot per minute. Airborne particulates are collected by passing air through a 47-mm glass-fiber filter. A dry gas meter is incorporated into the sampling stream to measure the total volume of air sampled in a given interval. The entire system is housed in a weatherproof structure. The filters are collected biweekly, and, to allow for the decay of radon daughter products, they are held for at least 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> at the E-LAB before being analyzed for gross-beta radioactivity (indicated as GR-B in the data tables). The biweekly filters are composited by location at the environmental laboratory for a quarterly gamma spectroscopy analysis.
In addition to station AP-I 1, which doubles as a REMP and demolition air particulate (DAP) monitor located just outside the site, three new airborne monitoring surveillance locations were established on-site for the detection of possible airborne radionuclides associated with demolition work. This monitoring is intended to provide supporting information from onsite monitoring of potential airborne releases. Results of those analyses are included in this report although they are not part of the REMP sampling.
4
Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 The collection and analysis of air particulate samples was removed from the Yankee ODCM (Amendment 18, August, 2005) during the year. The changes were made due to the removal of all significant airborne release pathways from the site. The off-site air particulate monitoring locations were discontinued by the end of September, with the exception of location AP-I I (observation stand, a former ODCM required location), and the on-site location DAP-2 (on the ISFSI pad) which continued for the entire year as a voluntary supplemental information station.
2.5.2 River Water Sampling An automatic composite sampler is located at one downstream sampling location. The sampler is controlled by a timer that collects an aliquot of river water at least every two hours over a period of one month. In addition, river water grab samples are collected monthly at Sherman Pond, near the plant site, and at one upstream location (control). All river water samples are preserved with HCL and NaHSO 3 or HNO3 at the laboratory to prevent the plate-out of potentially present radionuclides on the container wall over time. Each sample is analyzed for gross-beta and gamma-emitting radionuclides. The monthly samples are composited quarterly by location at the E-LAB for a tritium analysis. The monthly samples are also analyzed monthly beyond the minimum requirements of the ODCM.
2.5.3 Ground Water Sampling Grab samples are collected monthly from two on-site locations (potable water well at WG-I I and Sherman Spring, WG-12). The ODCM requires samples to be collected at least once per quarter. Each sample is required by the ODCM to be analyzed for gamma-emitting radionuclides and tritium. Samples are also analyzed for gross beta activity, which is beyond ODCM requirements. Gross beta analyses are performed to gather additional data that may help to provide early detection of site-related activity.
2.5.4 Storm Drain Water Sampling Grab samples are collected monthly or as available from the East and West Storm Drains. These are not ODCM required environmental sampling locations, but are included as supplemental samples. The two sample locations are comprised of a network of storm drains connected to parking areas, associated facility, and administration building, as well as groundwater and precipitation (including snowmelt) draining from the east side and west side of the site facility. Each sample is analyzed for gross-beta and gamma-emitting radionuclides and tritium. The storm drains are also utilized for construction de-watering discharges in accordance with the site's ODCM and NPDES effluent discharge requirements that includes analysis of effluents prior to release.
2.5.5 Sediment Sampling Shoreline sediment cores are collected semiannually from two locations, one upstream and one downstream of the site. At each location, six two-inch inner diameter plastic coring tubes are driven into the sediment at least six inches deep. The cores are carefully extracted and kept in an upright position and frozen prior to delivery to the E-LAB. At the E-LAB, the frozen cores are cut into 5 cm (two-inch) segments. For each location, the 0-5 cm segments are blended into a single sample, as are the 5-10 cm and 10-15 cm segments. These composite samples are then analyzed for gamma-emitting radionuclides.
An additional bottom sediment core is collected semiannually in Sherman Pond near the former plant discharge.
5
Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 2.5.6 Fish Sampling Fish samples are collected semiannually at two locations (upstream of the site and in Sherman Pond). A gill net is set overnight from a boat, and mixed species of fish are removed the following day. The species typically collected are yellow perch, smelt, pickerel, trout, bullheads or suckers. However, the makeup of any individual catch could be dominated by a single species available at the time. No attempt is made to differentiate sample analysis by fish species, such as those who primarily feed on the bottom and are closer to any radioactivity deposited in bottom sediments, from those species that feed higher in the water column. The limiting factor in fish sampling program is the availability of sufficient sample volume needed for analysis, making the differentiation of species typically impractical. The fish samples are frozen and delivered to the environmental laboratory where the edible portions are analyzed for gamma-emitting radionuclides.
2.5.7 Food Product Sampling Food products are collected annually (at harvest) at three locations. The samples collected in 2005 included broad leaf vegetable, above-ground vegetables and fruit. Two indicator locations are chosen as a result of historical annual Land Use Census and based on meteorological dispersion calculations. The third location is a control, which is located sufficiently far away from the site to be outside any potential influence from it. The edible portions of the samples are then analyzed at the environmental laboratory for gamma-emitting radionuclides.
The collection and analysis of food product vegetation samples was removed from the Yankee ODCM (Amendment 18, August, 2005) during the year. The changes were made due to the removal of all significant airborne release pathways from the site. As a completion of the REMP element, the last food products were collected in August, 2005.
2.5.8 Maple Syrup Sampling Maple syrup is an important commercial product in northern New England, including in the neighborhood of YR site. Consequently, samples are collected annually from two locations although there is no ODCM requirement. These samples are collected from the syrup manufacturer as a finished product, that is, following the boiling down of the maple sap that, in theory, concentrates any radioactive particulates in the media, thereby increasing the probability of detection. Since the samples have already been boiled down as part of the syrup production process, no preservatives are needed in the samples. Following collection, the samples are analyzed at the E-LAB for gamma-emitting radionuclides. It should be noted that because of the boiling down and filtering of the sap, the resulting radionuclide measurements do not represent actual environmental concentrations. It is estimated that the resulting syrup has been concentrated by a factor of from 15 to 120 times the original sap, depending mostly on the time of the season that the sap was collected.
The collection and analysis of maple syrup samples was removed from the Yankee ODCM (Amendment 18, August, 2005) during the year. The changes were made due to the removal of all significant airborne release pathways from the site. Samples for 2005 were collected (March - April) and analyzed as the last set of this media type prior to its elimination from the REMP.
6
Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 2.5.9 TLD Monitoring Direct gamma radiation exposure is continuously monitored with the use of thermoluminescent dosimeters (TLDs). Specifically, Panasonic UD-80 1ASI and UD-8 14AS I calcium sulfate dosimeters are used, with a total of five elements in place at each monitoring location. Each pair of dosimeters is sealed in a plastic bag, which is in turn housed in a plastic-screened container. This container is attached to an object such as a tree, fence or utility pole. TLDs are posted at 33 locations, 24 which are required by the ODCM (prior to Revision 18 of the ODCM). All the TLDs are read out quarterly.
During 2002, new sets of 16 TLDs were installed at locations to monitor the Independent Spent Fuel Storage Installation (ISFSI) prior to, during and following completion of fuel transfer. These locations are listed in Table 2-3. In 2004, one of the ISFSI TLD locations (IF-18) was relocated about 60 feet closer to the storage pad. This was necessary when the Screen Well House, upon which the TLD had been mounted, was demolished as part of site decommissioning activities. The ISFSI TLD monitoring is not part of the REMP program but will be continued as part of the overall ISFSI surveillance program following the Part 50 license termination for the rest of the site.

Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 3.0 RADIOLOGICAL DATA
SUMMARY
TABLES This section summarizes the analytical results of the environmental samples that were collected during 2005. These results, shown in Table 3-1, are presented in a format similar to that prescribed in the NRC's Radiological Assessment Branch Technical Position on Environmental Monitoring (Reference 1). The results are ordered by sample media type and then by radionuclide for the pathways described in Section 2.3. A comparison of indicator stations versus control stations is presented. Table 3-2 provides the same information for TLD direct radiation measurements.
The left-most column contains the radionuclide of interest, the total number of analyses for that radionuclide in 2005.
and the number of measurements which exceeded the Reporting Levels found in Table 4.2 of the YR ODCM. TIhe latter are classified as "Non-routine" results. The second column lists the required Lower Limit of Detection (LLr)) Ibr those radionuclides, as specified in the ODCM Table 4.3. The absence of a value in this column indicates that no L.1) is specified in the ODCM for that radionuclide in that media. The target LLD for any analysis is typically 30-40 percent of the most restrictive required LLD. Occasionally the required LLD is not met. This is usually due to malfunctions in sampling equipment, which result in low sample volume. Such cases are addressed in Section 4.2.
For each radionuclide and media type, the remaining three columns summarize the data for the following categories or monitoring locations: (1) the indicator stations, which are within the range of influence of the site and which could conceivably be affected by site activities; (2) the station which had the highest mean concentration during 2005 6or tatl radionuclide; and (3)the control stations, which are beyond the influence of the site. Direct radiation monitoring stations (using TLDs) are grouped into Indicator, Outer Ring, Fence line and Control stations.
In each of these columns, for each radionuclide, the following are given:
- the mean value of all concentrations including negative values and values that are not considered "detectable".
- the lowest and highest concentration, and
- the number of detectable measurements divided by the total number of measurements.
A sample is considered to yield a "detectable measurement" when the concentration exceeds three times its associated standard deviation. The standard deviation on each measurement 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.
The radionuclides reported in this section represent those that: 1)had a Reporting Level listed in Table 4.2 of the ODCM or, a LLD requirement in Table 4.3 of the ODCM, or 2) had a positive measurement of radioactivity, whether it was naturally-occurring or man-made; or 3) were of specific interest for any other reason. The radionuclides that are routinely analyzed and reported by the E-LAB in a gamma spectroscopy analysis includes: Ac-Th-228, Ag-I 08m.
Ag-i lOm, Ba-140, Be-7, Ce-141, Ce-144, Co-57, Co-58, Co-60, Cr-51, Cs-134, Cs-137, Fe-59,1-131, K-40. La-1410.
Mn-54, Nb-95, Ru-103, Ru-106, Sb-124, Sb-125, Se-75, Zn-65 and Zr-95. In no case did a radionuclide not shown in Table 3-1 appear as a "detectable measurement" during 2005.
Data from direct radiation measurements made by TLDs are provided in Table 3-2 in a format essentially the same as above. The complete listing of quarterly TLD data is provided in Table 3-3. Table 3-4 contains a list of new TFI)s placed to monitor the Yankee ISFSI site. Locations of these, including two located offsite, are shown in Figures 2-4 and 2-7.

Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 4.0 ANALYSIS OF ENVIRONMENTAL RESULTS 4.1 SAMPLING PROGRAM DEVIATIONS ODCM Control 4.1 allows for deviations "if specimens are unobtainable due to hazardous conditions, seasonal unavailability or malfunction of automatic sampling equipment." Deviations noted in the REMP program during 2005.
included the following:
- In January the composite sampler at station WR-l I was taken off-line for maintenance. Subsequently. the hydroelectric power station, where the sampling equipment is located, went down for maintenance preventing sampling from the designated location in January, February and March. Grab samples were taken downistreamll of the site as a replacement.
- In June (2nd quarter) TLD GM-29 was missing at time of collection.
- In June the composite sampler at station WR-I I was found out of service due to damage to the sampler motor.
Repair of sampler was completed and placed back in service on 07/21/05.
- The 4h quarter TLD at location GM-40 was found missing at time of collection.
Routine non-REMP required sample collections encountered the following departures from the planned sample collection schedule:
- A site remediation project prevented access and sampling from the on-site East Storm Drain (WW-5 1) Il the entire year.
- A site remediation project prevented access and sampling, and/or no rain (dry drain conditions) from the on-site West Storm Drain (WW-52) for the months of January, February, March, June, July (lack of water).
August (lack of water), and September (lack of water) of 2005.
- A site decommissioning remediation project prevented access and collection of river water samples at WR-31 (Sherman Pond near former plant discharge) for January, February, and March of 2005.
4.2 COMPARISON OF ACHIEVED LLDS WITH REQUIREMENTS Table 4.3 of the ODCM (Table 2-4 in this report) gives the required Lower Limits of Detection (LLDs) for environmental sample analyses. On occasion, an LLD is not achieved due to situations such as a low sample volume caused by sampling equipment malfunction. In such a case, Control 7.1 of the ODCM requires a discussion of the situation in the Annual Radiological Environmental Operating Report. At the E-LAB, the target LLD for any analysis is typically 3040 percent of the most restrictive required LLD. Expressed differently, the typical sensitivities achieved for each analysis are at least 2.5 to 3 times better than that required by the YR ODCM.
- For each analysis having an LLD requirement in ODCM Table 4.3, the a posteriorior after the fact LLD (or minimum detectable concentration - MDC) calculated for that analysis was compared with the required a pri ri LLD. Of the 612 analyses performed with a specified LLD requirement in 2005, no sample failed to meet the requirements of Table 4.3 of the ODCM for minimum level of detection.
36
Yankee Nuclear Power Station Annual Radiological Environmental Operating Reporl 2(005 4.3 RESULTS COMPARED AGAINST REPORTING LEVELS ODCM Control 4.1 .a. requires the written notification to the NRC within 30 days whenever a Reporting Level in ODCM Table 4.2 is exceeded. Reporting Levels are the environmental concentrations that relate to the ALARA dcsign dose objectives of 10 CFR 50, Appendix 1. It should be noted that environmental concentrations are averaged over calendar quarters for the purposes of this comparison, and that Reporting Levels apply only to measured levels of radioactivity due to site effluents. During 2005, no Reporting Levels were exceeded.
4.4 DATA ANALYSIS BY MEDIA TYPE The 2005 REMP data for each media type are discussed below. These are arranged in the same order as in Table 3-I and are further categorized by pathway. Graphical plots of monitoring data are also shown in Figures 4-1 to 4-l I. All values are plotted, whether they are "detectable" or "non-detectable."
4.4.1 Air Particulates (See Figures 4-1 & 4-2)
Biweekly air particulate filters were obtained from each of the six REMP sampling sites over the first nine months of 2005. Five are indicators stations, AP-I 1, -12, -13, -14, and -31 in the site vicinity, and one is a control station.
AP-3 1in Williamstown, MA. Filters are analyzed for gross-beta radioactivity. At the end of each quarter, the individual filters collected during the quarter from each sampling site were composited for a gamma analysis. The results of the biweekly air-particulate sampling program are shown in Table 3-1 and Figures 4-1 through 4-2. The YR ODCM requirement for this sampling was eliminated in July, 2005 with Revision 18 to the ODCM. This revision to the ODCM was made since all significant sources of airborne radioactivity had been eliminated from the site during the course of decommissioning.
Supplemental environmental air particulate monitoring to assess demolition activities was initiated in 2004 to validate effluent release (demolition airborne dust) monitoring. On-site sampler designations were DAP-1, 2, 3, and 4 (DAP-4 same location as AP-1 I). Locations are described in Table 2-2. Results of those analyses are included in summary data in Appendix C of this report, although they are not part of the REMP sampling.

As shown in Figure 4-1, there has been no significant difference between the airborne concentrations (as measured by gross beta activity) at the indicator (near-site) stations and the control (distant from site) stations.
Figure 4-2 shows the biweekly gross beta concentration over the last three years at each air particulate sampling location required by the ODCM along with the control air particulate sampling location at AP-2 1 (Williamstown, MA).
It can be seen that the gross-beta measurements on air particulate filters fluctuate significantly over the course of a year. This is due principally to seasonal variations and the related effects on naturally occurring terrestrial radionuclide emissions. The measurements from control station AP-2 1 vary similarly, indicating that these fluctuations are due to regional changes in naturally-occurring airborne radioactive materials, and not due to site operations. Table 3-1 shows that the mean concentration from indicator stations, on the average, are similar to those from control locations, further supporting this conclusion.

This consisted of four non-REMP sample locations, DAP-1, 2, 3 and 4. No site-related radioactivity was detected in samples from these locations in 2005. Results are provided in Appendix C.
4.4.2 River Water (See Figure 4-3)
Aliquots of river water were automatically collected every two hours from the Deerfield River downstream from the site (WR-I I at Bear Swamp Lower Reservoir). These composited samples were collected monthly and sent to the environmental laboratory for gamma, tritium, and gross beta analyses. Monthly grab samples were also collected at the Harriman Reservoir control location and at Sherman Pond near the discharge area (WR-21 and -31, respectively).
Table 3-1 shows that gross-beta measurements were positive in five of the twenty-one samples collected from indicator locations, and two of twelve samples from the control site. This result is consistent with past measurement history in the water. No detectable levels of site-related radioactivity were found in any of the 2005 river water samples by tritium or gamma spectroscopy analyses.
The historical concentrations of gross beta activity at the indicator and control locations have not been significantly different, as shown in Figure 4-3, except during the last half of 1992, 1998-1999, and in 2002 when the levels at WR- 11 were slightly elevated relative to the control, but no tritium or site related gamma emitter was detected in any sample set for these years of elevated gross beta activity. The gross beta activity was attributed to naturally-occurring 39 0/
Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 radioactivity as discussed in the earlier Annual Radiological Environmental Operating Reports. For 2005, the control station gross beta results averaged above the indicator station values by a small amount, with both the indicator and control station averages generally in close agreement, suggesting no significant difference between the control location and indicator samples in 2005.

Monthly ground water samples were collected from two on-site locations during 2005, the site potable water well (WG- 11) and Sherman Spring (WG- 12), although quarterly samples are all that are required by ODCM Table 4.1.
Table 3-1 shows that gross-beta measurements were positive in most of the samples, an outcome typical for ground water samples. This is due to naturally-occurring radionuclides in the water.
Tritium was detected in nine of twelve samples from WG-12 (Sherman Spring) during 2005. Concentrations are elevated above the range of values for the past 9 years during which a very low or non-detectable concentration of tritium had been observed (Figure 4-4). The detected increases are attributed to disturbance of the aquifer associated with source removal during decommissioning and increased infiltration due to removal of structures, pavement and storm water drainage systems. Peak tritium concentration remained well below ODCM reporting levels. Water from Sherman Spring flows into the Deerfield River. Neither the Deerfield River nor Sherman Spring is used for drinking water. No tritium was detected in any of the monthly samples from the on-site potable water well (WG- 11). No gamma-emitting radionuclides were detected in any of the ground water samples from either WG-1 1 or WG-12.

Lack of access to sampling locations due to site remediation activities and/or lack of rainfall allowed only 5 samples to be collected during 2005 from the West Storm Drain (WW-52). Each sample was analyzed for gross-beta and gamma-emitting radionuclides and tritium. Gross-beta measurements were positive in all of the samples taken and were consistent with those from the previous year. No gamma-emitting radionuclides were detected in any of the samples. A low level of tritium, just above the detection limits for the analysis, was detected in two of the five samples. A possible source for this activity is the same as that for the tritium in 2005 Sherman Spring samples, namely the disturbance of the aquifer associated with source removal during decommissioning and increased infiltration due to removal of structures, pavement and storm water drainage systems. The water from site storm drains discharges to the Deerfield River, which is not used for drinking water.
4.4.5 Sediment (See Figures 4-5, 4-6, & 4-7)
Semiannual sediment core samples were collected from three locations during 2005. Indicator stations SE-91 and SE- 1I are located in Sherman Pond and downstream about 24 river miles at No. 4 Dam in Charlemont, MA, respectively. Control station SE-21 is located upstream (control) at Harriman Reservoir. Each sample is segmented by depth (0-5, 5-10, 10-15 cm) and analyzed for gamma-emitting radionuclides. As would be expected, naturally-occurring K-40 and Th-232 were detected in all ofthe samples. In addition to those naturally-occurring radionuclides.
Cs-137 was also detected in 16 of 18 segments from all three locations. These results are consistent with what has been measured in previous years. Presence of Cs-137 at Station SE-Il and SE-21 is attributed to nuclear weapons test ino 41
Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 fallout as the far downstream location and the upstream control location indicate similar levels of Cs-137. Samples from Station SE-91, near the site have in general about 5 times higher Cs-137 concentration, attributable in part to station licensed discharges in past years. In past years, sediment analysis at SE-91 have also shown positive indication of Co-60 which can be related to site discharges, although no current analysis for Co-60 give positive indication of its presence. It should also be noted that the sample for Station SE-91 is taken from bottom of the Sherman Pond and is high in organic material, which has been found to concentrate fallout Cs- 137 more than soils/sediments low in organic material. Stations SE- 11 and SE-21 are taken from the shoreline and have not typically had the same organic material content as in SE-91. Figure 4-5 shows the consistent range in Cs-137 levels over the last nine years in the down stream (24 miles) sampling location.

At both the indicator and the control location, the character of the sediment is highly dependent on the specific location sampled, and it also can depend on the water level in Harriman Reservoir or on the Deerfield River shoreline at the time of sampling. The diverse character of the sediment at either location, and the fact that Cs-I 37 tends to bind more to finer-grained sediment containing organic matter than to sandy and rocky sediment, as well as the dynamic nature of their fluvial environments, leads to a wide range of Cs-137 concentrations, as shown in Figures 4-5 through 4-7.

These samples were collected from a deep water location opposite the plant former discharge into Sherman Pond. It is believed that the higher Cs-137 levels at SE-91, whether due to fallout or site effluents, are also related to the character of the sediment (a rich organic benthos layer) at the bottom of Sherman Pond at this location as described earlier. The levels of Cs-137 observed in 2005 are not significantly different from levels observed at location SE-91 in the last few years, which is about a factor of two lower than levels seen in the late 1990's and early 2000's time frame.

Semiannual samples of fish were collected from two locations during 2005, FH-l 1, an indicator station in Sherman Pond, and FH-2 1, a control station in Harriman Reservoir. The edible portions of each of these samples were analyzed for gamma-emitting radionuclides. As expected in aquatic animals, naturally-occurring K-40 was detected in all samples from both locations. No site-related gamma emitting radionuclides were detected in 2005 fish samples. The average 2005 Cs-137 concentrations shown in Figure 4-8 include the results of counting statistics on sample measurements, even when the analysis counts did not exceed the criteria for a "positive" (detectable) determination. The wide variation in relative Cs-137 activity illustrated in Figure 4-8 over past years is suspected to be due to the different species of fish and their specific eating habits. Fish that are bottom feeders tend to accumulate more of the Cs-137 activity from aquatic sediment than fish that feed higher in the water column. The makeup of any individual catch (fish sample) could be dominated by a single species available at the time, and no attempt is made to differentiate sample analysis by fish species, such as those who primarily feed on the bottom versus those species that feed higher in the water column.

Samples were analyzed for gamma-emitting radionuclides. K-40 (naturally occurring) was detected in all three samples. No site-related gamma emitting radionuclides were detected in 2005 food samples.
The collection and analysis of food samples was removed as a requirement from the YR ODCM during 2005 due to the removal of all significant sources for airborne releases from the site. No additional food sample collections are planned beyond those that were collected in 2005.
4.4.8 Maple Syrup Processed maple syrup samples were collected from an indicator and control location at the end of March 2005. The indicator station is MS-33 in Rowe, MA, and the control station, MS-45, is in the town of Florida, MA. These samples represent concentrated media, relative to the original tree sap, produced by boiling (see Section 2.5.8). Naturally-occurring K-40 was detected in both samples. No site related radionuclides were detected in any sample.

Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 4.4.9 Direct Radiation (See Figures 4-9, 4-10 & 4-11)
Direct radiation was continuously measured at 33 locations surrounding Yankee Rowe site in 2005 with the use of thermoluminescent dosimeters (TLDs). These were collected each calendar quarter for readout at the E-LAB.
As shown in Figure 4-9, there is a distinct annual cycle at both indicator and control locations. The lowest point of the cycle occurs during the winter months. This is due primarily to the attenuating effect of the snow and frozen ground cover on radon emissions and on direct irradiation by naturally-occurring radionuclides in the soil. Differing amounts of these radionuclides in the underlying soil, rock or nearby building materials result in different radiation levels between one field site and another.

This indicates that there was no significant overall increase in direct radiation exposure rates in the site vicinity beyond the industrial area of the site.
As shown in Figure 4-10, the levels at offsite locations in 2005 are consistent with or bounded by levels in previous years. The largest variance occurred in the 3rd quarter at GM-07 (an outer ring location 6.6 km northwest) which was slightly higher than the normal observed trends. All other inner (closer) indicator locations exhibited consistently lower values indicating that the single high reading at GM-07 is not related to site operations.

These TLDs are located on the fence surrounding the inner restricted area within the Yankee Rowe site property bounds, and are influenced by the ISFSI. Specifically, the elevated exposure rates at TLD locations GM-18, -19, and -20 since 2002 are due to fuel and GTCC transfer activities to the ISFSI, completed during 2003, and storage of spent fuel at the ISFSI and other decommissioning activities that move and temporarily disturb the earth at various locations across the site.

Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 5.0 OFF-SITE DOSE EQUIVALENT COMMITMENTS The purpose of this section is to evaluate off-site dose consequences (dose equivalent commitments) associated with detectable site related radioactivity in environmental media. The method utilizes Regulatory Guide 1.109 (Reference 2)
ODCM models and actual measurements of the concentrations of radioactivity in various environmental media (e.g.. air.
sediment, ground water) to compute the dose consequences resulting from the inhalation or ingestion of such material.
These evaluations can be used to provide assurance that the station's radioactive liquid and airborne effluent dose models are unlikely to underestimate actual impacts.
The standards for the maximum dose to an individual ofthe general public taken from 40 CFR190, is 25 mRem to the whole body, 75 mRem to the thyroid, and 25 mRem to any other organ. The dose commitment to be calculated in ihis section is also compared to the ALARA dose objectives of I OCFR50 Appendix I for liquid effluents of 3 mrem/year total body and 10 mrem/yr to any organ. These standards are a fraction of the USA background radiation of 300 m Rem per year given in NCRP 94 (Reference 3).
During 2005 there were no instances of site-related radioactivity observed in environmental media which have a direct human consumption or exposure pathway associated with it Low levels of tritium in Sherman Spring water samples wcrc detected, but this is a non-drinking water source. Cesium-137 most likely due to past plant operations was detected in sediment near the former plant discharge. However, sediments at the bottom of Sherman Pond are not part of a direct exposure pathway to humans.
In 2005 the potential dose for the postulated ingestion of 2 liters/day of Sherman Spring water, with an average concentration of 2403 pCi/liter tritium (observed 2005 average value of all positive measurements), would be approximately 0.18 mrem/yr (Adult, whole body), or about 6% of the ALARA dose objectives if Sherman Spring xwas used as a drinking water supply.
Since the REMP for 2005 did not indicate site related radioactivity in off-site media associated directly with human ingestion, there is no indication that the site's effluent dose models are not affectively estimating the dose impact to members of the public.

Yankee Nuclear Power Station Annual Radiological Envirommental Operating Report 2005 APPENDIX B - QUALITY ASSURANCE PROGRAM
SUMMARY
B-I
Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 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, 2005.
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 "spiked" with a known amount of radioactive material and are routinely submitted in triplicate to evaluate the bias and precision of a measurement process. Table B-I provides the summary of the process check results for January to December 2005. Of the 520 analyses, 100% passed the bias criteria and 100% of the 102 results evaluated for precision were acceptable. The FANPEL internal acceptance criteria are summarized at the end of Table B-l.
Third Party Cross Check Program The FANPEL participates in a third party cross check program managed by Analytics Inc. to satisfy the requirement of the Environmental Technical Specification/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 4h quarter 2004 through the 4th quarter 2005 are summarized in Table B-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 criteria, 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 B-1.
B-2
Yankee Nuclear Power Station Annual Radiological Environmental Operating Report 2005 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 32 paired samples in 2005. The measurements evaluated include twenty-six gamma emitting radionuclides, TRITIUM, 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 B-3. For the 2005 program, 99.5% (618/621) of the measurements met the FANPEL internal acceptance criteria.
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-six performance tests were conducted in 2005 by FANPEL and the third party tester. These tests were made on 16 separate sets of 6 dosimeters. All of the 16 TLD test sets passed the mean bias criteria of +/-20. 1%. Of the ninety-six 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.
