SUMMARY
The radiological environmental monitoring program for the Yankee Rowe Nuclear Power Station was continued for the period January through December 2003, in compliance with the Yankee Decommissioning Quality Assurance Program (YDQAP) 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 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 station and as far away as 22.2 kilometers. Radiochemical and radiological analyses of samples were performed to detect the presence of any station-related radioactivity. Samples collected include air-particulate filters, broad leaf vegetation, well water, fruits, vegetables, river water, bottom 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 station 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, farming practices, and feed type. 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 Rowe was permanently shutdown in 1991. Primary activities at the Yankee Rowe station are now focused on fuel storage, site remediation and facility decommissioning. Even though the station is no longer generating power, decommissioning activities include processing and discharging of liquids containing radioactivity and monitoring for any release of airborne radioactivity. However, the levels of radioactivity released are significantly lower than releases during plant operation. The radiological monitoring of the environment through this program will continue 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 outside sources, such as fallout from nuclear weapons tests and naturally occurring radionuclides. As typical of previous years, station-related radioactivity was observed in some of the monitoring samples. The specific observations of possible station effects included Cesium-137 in bottom sediment near the plant discharge point. Air sample results demonstrated that no plant-related airborne particulate activity was present in samples.
Milk sampling was discontinued due to absence of milk-producing animals in the plant vicinity. Milk was sampled since 2000 only at the control location in Williamstown, MA, 22 km from the plant due to the unavailability of milk form locations within 5 miles of the plant. The control location facility in Williamstown closed in December 2002.
LLDs for Mn-54, Zn-65, and Zr-Nb-95 were removed from the program as a result of changes to the YNPS ODCM.
These changes were prompted by the change in status of the plant as decommissioning continues.
During 2003, there were no other changes made to the radiological environmental monitoring program.

2.0 INTRODUCTION
2.1 General Plant Site Information The Yankee Nuclear Power Station (YNPS) 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 plant 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 YNPS.
Sherman Dam, immediately adjacent to YNPS, operates as a hydroelectric generating station. Sherman Pond, the impoundment behind this dam, has been used as a source of cooling water for YNPS.
YNPS voluntarily shut down on October 1, 1991 after 31 years of operation. The plant is involved in the process of decommissioning which involves the disassembly and removal of the plant components and structures. 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, Massachusetts Department of Public Health, and Massachusetts Emergency Management Administration.
The radiological environmental monitoring program for YNPS continued during 2003 and will continue throughout the decommissioning period until its 10CFR50 license is terminated.
2.2 Program Design The Radiological Environmental Monitoring Program for the YNPS 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 YNPS activities.
To provide assurance to regulatory agencies and the public that the environmental impact from YNPS 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.
These objectives will continue to be in force, to varying degrees, throughout decommissioning activities at the YNPS site. Due to the shutdown status of the plant and due to the relatively low quantities of radioactive material now 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 plant
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 3
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).
The program was designed to meet the intent of NRC Regulatory Guide 4.1, Programs for Monitoring Radioactivity in the Environs of Nuclear Power Plants; NRC Regulatory Guide 4.8, Environmental Technical Specifications for Nuclear Power Plants; the NRC Branch Technical Position of November 1979 entitled, An Acceptable Radiological Environmental Monitoring Program; and NRC NUREG-0472, Radiological Effluent Technical Specifications for PWR's.
The environmental TLD program was designed and tested around NRC Regulatory Guide 4.13, Performance, Testing and Procedural Specifications for Thermoluminescence Dosimetry: Environmental Applications. The quality assurance program was designed around the guidance given in NRC Regulatory Guide 4.15, Quality Assurance for Radiological Monitoring Programs (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 plant to levels found in areas not influenced by the plant. 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 plant, 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 or radiation due to plant 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 Four pathway categories are 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 below, and are described in more detail in this section:
- Airborne Pathway
§ Air Particulate Sampling Section 2.5.1
- Waterborne Pathways
§ River Water Sampling Section 2.5.2
§ Ground Water Sampling Section 2.5.3
§ Storm Drain Water Sampling Section 2.5.4
§ Sediment Sampling Section 2.5.5
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 5
- Ingestion Pathways
§ Milk Sampling Section 2.5.6
§ Fish Sampling Section 2.5.7
§ Food Product (fruits & vegetables, Section 2.5.8 broad leaf vegetation)
§ Maple Syrup Sampling Section 2.5.9
- Direct Radiation Pathway
§ TLD Monitoring Section 2.5.10 2.5 Descriptions 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 - 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:
2.5.1 Air Particulate Sampling Continuous air samplers are installed at six locations, five of which are required by the YNPS 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 E-LAB for a quarterly gamma spectroscopy analysis.
2.5.2 River Water Sampling An automatic composite sampler is located at one downstream sampling location. The sampler is controlled by timers that collect an aliquot of river water at least every two hours over a period of one month. Grab samples are collected monthly at Sherman Pond and at one upstream location. All river water samples are preserved with HCl and NaHSO3, or HNO3, to prevent the plate out of potentially present radionuclides on the container walls. 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 H-3 analysis. The monthly H-3 samples are also analyzed as a non ODCM requirement.
2.5.3 Ground Water Sampling Grab samples are collected monthly from two on-site locations. The ODCM requires samp les to be collected at least once per quarter. Each sample is required by the ODCM to be analyzed for gamma-emitting radionuclides and H-3.
Samples are also analyzed for gross beta activity, which is not an ODCM requirement. Gross beta analyses are performed to gather additional data that may help to provide early detection of plant-related activity.
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 6
2.5.4 Storm Drain Water Sampling Grab samples are collected monthly or as available from the East and West Storm Drain. These are not ODCM required sampling locations. This water is 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 plant facility. Neither storm drain network is directly connected to any plant operation. Each sample is analyzed for gross-beta and gamma-emitting radionuclides and H-3.
2.5.5 Sediment Sampling Shoreline sediment cores are collected semiannually from two locations, one upstream and one downstream of the plant. 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 plant discharge. A Wildco K. B. Core Sampler, fitted with a plastic coring tube, is dropped from a boat. Six cores are collected here, and are processed and analyzed as described above.
2.5.6 Milk Sampling Samples collected to measure radionuclides in milk were discontinued in 2002 and this requirement was removed from the ODCM in 2003. Due to absence of milk-producing animals in the plant vicinity since 1999 this medium had been sampled since 2000 only at a control location in Williamstown, MA, 22 km from the plant. That facility closed in December 2002 and milk animals are no longer present there. Milk sampling was discontinued because the radionuclides that accumulate in milk are no longer potentially released from the plant, and no suitable indicator or control stations remain to provide samples.
2.5.7 Fish Sampling Fish samples are collected semiannually at two locations (upstream of the plant 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. The fish samples are frozen and delivered to the E-LAB where the edible portions are analyzed for gamma-emitting radionuclides.
2.5.8 Food Product Sampling Food products are collected annually (at harvest) at three locations. The samples are either tuberous vegetables, above-ground vegetables, or fruit. Two indicator locations are chosen as a result of the annual Land Use Census, based on meteorological dispersion calculations. The third location is a control, which is located sufficiently far away from the plant to be outside any potential influence from it. The edible portions of the samples are then analyzed at the E-LAB for gamma-emitting radionuclides.
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 7
2.5.9 Maple Syrup Sampling Maple syrup is an important commercial product in northern New England, including the YNPS plant environs.
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. 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 mo stly on the time of the season that the sap was collected.
2.5.10 TLD Monitoring Direct gamma radiation exposure is continuously monitored with the use of thermoluminescent dosimeters (TLDs).
Specifically, Panasonic UD-801AS1 and UD-814AS1 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, with 24 of these stations required by the ODCM. All the TLDs are read out quarterly.
Normandeau posts and retrieves all TLDs, while the E-LAB processes them.
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. The ISFSI TLD monitoring is not part of the REMP program but will be incorporated in the program following structure demolition and license termination.

SUMMARY
TABLES This section summarizes the analytical results of the environmental samples that were collected during 2003. 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. The units for each media type are also given. 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 2003, and the number of measurements which exceeded the Reporting Levels found in Table 4.2 of the YNPS ODCM. The latter are classified as "Non-routine" results. The second column lists the required Lower Limit of Detection (LLD) for those radionuclides, which have detection capability requirements as specified in the ODCM Table 4.3. The absence of a value in this column indicates that no LLD 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 of monitoring locations: (1) the Indicator stations, which are within the range of influence of the plant and which could conceivably be affected by plant activities; (2) the station which had the highest mean concentration during 2003 for that radionuclide; and (3) the Control stations, which are beyond the influence of the plant. Direct radiation monitoring stations (using TLDs) are grouped into Indicator, Outer Ring, Fenceline 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.
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-108m, Ag-110m, Ba-140, Be-7, Ce-141, Ce-144, Co-57, Co-58, Co-60, Cr-51, Cs-134, Cs-137, Fe-59, I-131, K-40, La-140, 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 2003.
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 TLDs placed to monitor the YNPS ISFSI. Locations of these, including two located offsite, are shown in Figures 2.4 and 2.7.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 35 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." There were no program deviations noted in the REMP during 2003.
During the week of January 15th, the sampling pump for the air particulate sampling station 21 failed causing a low volume sample to be collected.
No air particulate sample was collected from Station 21 (Williamstown) for the period of April 3rd to April 15th due to an improperly mounted air filter.
A set of TLDs placed at location GM -29 (Route 8A) was found missing in late June, 2003. Modifications to the mounts to better secure them to existing structures were carried out.
Air particulate sampling station 11 (Observation Stand) and river water sampling station 11 were found shut off on July 15th due to a power outage. Samplers were placed back in service within 21 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br />.
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 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 better than that required by the YNPS ODCM.
For each analysis having an LLD requirement in ODCM Table 4.3, the a posteriori or after the fact LLD calculated for that analysis was compared with the required LLD. O f the more than 830 analyses performed with a specified LLD requirement in 2003, 100% met the requirements of Table 4.3 of the ODCM in 2003.
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 design dose objectives of 10 CFR 50, Appendix I. 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 plant effluents. During 2003, no Reporting Levels were exceeded.
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 36 4.4 Data Analysis by Media Type The 2003 REMP data for each media type are discussed below. These are arranged in the same order as in Table 3.1, and are further categorized by pathway. Graphical plots of monitoring data are also shown in Figures 4-1 to 4-11. With respect to data plots, all values are plotted, whether they are "detectable" or "non-detectable."
4.4.1 Air Particulates The biweekly air particulate filters from each of the six operating sampling sites. Five are indicators stations, AP-11, -12, -
13, -14, and -31 in the plant vicinity, and one control station, AP-31in 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.

0.01 0.02 0.03 0.04 0.05 Control Indicators As shown in Figure 4-1, there has been no significant difference between the concentration at the indicator (near-plant)
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 37 stations and the control (distant from plant) stations.
Figure 4-2 shows the biweekly gross beta concentration at each air particulate sampling location required by the ODCM along with the control air particulate sampling location at AP-21 (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-21 vary similarly, indicating that these fluctuations are due to regional changes in naturally-occurring airborne radioactive materials, and not due to YNPS 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.

These composited samples were collected monthly and sent to the E-LAB for gamma, tritium and gross beta analysis. 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 six of the thirty-nine samples collected, as might be expected, due to naturally-occurring radionuclides in the water. The historical concentrations 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 other plant related gamma emitter was detected in either sample set in 2002. This was attributed to naturally-occurring radioactivity as discussed in the earlier Annual Radiological Environmental Operating Reports. For 2003, the indicator station gross beta results
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 38 averaged below the control station values by a small amount, with both the indicator and control station averages in close agreement for the second half averages suggesting no significant difference between the control location and indicator samples in 2003. In addition, no tritium or gamma spectroscopy analyses found detectable levels of plant-related radioactivity in any of the 2003 river water samples.

WR-11 Bear Swamp Lower Reservoir WR-21 Harriman Reservoir During the fall of 2003 all water was drained from the YNPS Spent Fuel Pool as part of plant decommissioning activities and in accordance with NPDES and effluent ODCM requirements. The water from the fuel pool was treated and released to the Deerfield River. During the release a number of special river water samples were taken to monitor any radiological consequences at Station 91 in Sherman Pond near the release point. These included three samples analyzed for tritium and twenty-eight gamma spectroscopy analyses. None of those samples contained detectable levels of radioactivity.
4.4.3 Ground Water Monthly ground water samples were collected from two on-site locations during 2003, the plant potable water well and Sherman Spring, WG-11 and -12, respectively (only quarterly samples are required by ODCM Table 4.1). Table 3.1 shows that gross-beta measurements were positive in most of the samples. This is due to naturally-occurring radionuclides in
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 39 the water.
Tritium was not detected in any of the samples from either sample location. A steadily decreasing concentration of H-3 has been detected in previous years in WG-12 (Sherman Spring) samples, as shown in Figure 4-4. The water from Sherman Spring leaves the ground on YNPS property and flows into the Deerfield River. Neither the Deerfield River nor Sherman Spring is used for drinking water.
No gamma-emitting radionuclides or plant-related radioactivity were detected in any of the ground water samples.

Each sample was analyzed for gross-beta and gamma-emitting radionuclides and H-3. Gross-beta measurements were positive in most of the samples taken, as would be expected. The levels are consistent with those from previous years. Three samples had gross beta results below detectable limits. No gamma-emitting radionuclides or H-3 were detected in any of the samples.
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 40 4.4.5 Sediment Semiannual sediment core samples were collected from three locations during 2003. Indicator stations SE-91 and SE-11are located in Sherman Pond and at No. 4 Dam, respectively, and control station SE-21 is located at Harriman Reservoir. Each set of samples was 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 most of the samples.
In addition to the naturally-occurring radionuclides, Cs -137 was detected in just over 42% of the segments. The result from the 10-15 cm depth segment from downstream location SE-11 (Figure 4-5), while elevated, is consistent with what has been measured in previous years and is bounded by levels previously reported at the control location (SE-21) reported in 1987 and 1995. It is attributed to nuclear weapons testing fallout. The Cs -137 in the 0-5-10 cm and 10-15 cm depth segments at SE-11 are bounded by levels previously reported at the same location.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 41 Results from the upstream (SE-21) control location are also elevated (Figure 4-6), but also are bounded by levels previously reported at that location. At both the indicator and the control location, the character of the sediment is highly dependent on the specific location sampled, which in turn is dependent 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-137 tends to bind more to finer-grained sediment containing organic matter than to sandy and rocky sediment leads to a wide range of Cs -137 concentrations, as shown in Figures 4-5 through 4-7.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 42 Table 3.1 and Figure 4-7 show the levels of Cs -137 at station SE-91. These samples were collected from a deep water location near the plant discharge in Sherman Pond. Although much of the Cs -137 in this sediment is due to global nuclear weapons testing fallout, some of the Cs -137 in these samples might be due to effluents released from monitored plant discharges. It is believed that the higher Cs -137 levels at SE-91, whether due to fallout or plant effluents, are related to the physical make-up of the sediment (rich organic benthic layer) at the bottom of Sherman Pond.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 43 4.4.6 Fish Semiannual samples of fish were collected from two locations during 2003, FH-11, an indicator station, Sherman Reservoir, and FH-21, a control station, Harriman Reservoir. The edible portions of each of these were analyzed for gamma-emitting radionuclides. As expected in biological matter, naturally-occurring K-40 was detected in all samples. No other gamma emitting radionuclides were detected in 2003 fish samples. The average Cs -137 concentrations shown in Figure 4-8 are not considered detectable or "positive" measurements. The wide variation in Cs -137 activity is primarily due to the different species of fish and the specific eating habits of the fish. Fish that are bottom feeders would tend to pick up more of the Cs -
137 activity located in the water sediment. One of four samples taken in 2003 had a detectable level of Cs -137. Although the presence of Cs -137 in this media is historically attributed to residual weapons testing fallout, the Cs -137 in fish is conservatively treated as a possible plant-related nuclide with the dose consequence assessed in Section 5.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 44 4.4.7 Food Three food samples were collected from indicator stations TF-11 and -13 in Monroe Bridge and Monroe, MA, respectively, and from a control station, TF-21 in Williamstown, MA during 2003. Samples were analyzed for gamma-emitting radionuclides. K-40 was detected in all three samples. No other gamma emitting radionuclides were detected in 2003 food samples.
4.4.8 Maple Syrup Processed maple syrup samples were collected from an indicator and control location during the month of April 2003. The indicator station is MS-33 in Rowe, MA, and the control station, MS-45, is in Florida, MA. These samples represent concentrated media, relative to the original tree sap, by boiling (see Section 2.5.9). Naturally-occurring K-40 and Cs-137 were detected in both samples. The concentrations of Cs -137 in 2003 samples are consistent with that detected in both indicator and control samples in previous years, and is attributed to global nuclear weapons testing fallout.
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 45 4.4.9 Direct Radiation Direct radiation is continuously measured at 33 locations surrounding YNPS with the use of thermoluminescent dosimeters (TLDs). These are collected every 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 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.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 46 From Table 3.2 and 3.3, it can be seen that the mean exposure rates for the Indicator, Outer Ring, and Control categories were not significantly different in 2003. This indicates that there was no significant overall increase in direct radiation exposure rates in the plant vicinity beyond the industrial area of plant structures. As shown in Figures 4-10 and 4-11, the levels at offsite locations in 2003 are consistent with or bounded by levels in previous years.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 47 Results from the Fenceline TLDs are shown in Figure 4-11 and summarized in Tables 3.2 and 3.3. These TLDs are located on the fence surrounding the Radiation Control Area within the YNPS property bounds, and are influenced by the ISFSI.
Specifically, the elevated exposure rates at TLD locations GM-18, -19, and -20 during 2003 are due to fuel and GTCC transfer activities to the ISFSI completed during 2003.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 48 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 plant 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 stations radioactive liquid and airborne effluent dose models are unlikely to underestimate actual impacts.
The standards for the maximum dose to an individual of the 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. These standards are a fraction of the USA background radiation of 300 mRem per year given in NCRP 94 (Reference 3).
During 2003 there were no instances of plant-related radioactivity observed in environmental media with the possible exception of Cs-137 in sediment near the plant discharge structure. Detected levels of radioactivity attributable to natural processes or fallout include gross beta and Be-7 in air particulate samples, and gross beta in water samples, K-40 and Cs-137 in fish, K-40 and Cs-137 and Ac-Th-228 in river sediment.
A detected level of Cs -137 in one of four fish samples is conservatively evaluated. The measured level represents a potential annual dose commitment to a maximum exposed individual of 0.044 mRem (Teen, Liver) has been estimated using conservative assumptions regarding consumption rate and a constant Cs -137 concentration of 57 pCi/kg in fish. This dose is 0.18% of the Standard Dose Limit of 25 mRem.
Since the REMP for 2003 did not indicate plant related radioactivity in off-site media associated directly with human inhalation or ingestion, there is no indication that the plants effluent dose models underestimate the dose impact to members of the public.

Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 A-1 APPENDIX A - LAND USE CENSUS FOR 2003
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 A-2 APPENDIX A - LAND USE CENSUS FOR 2003 A Land Use Census is conducted annually between the dates of June 1 and October 1 to identify the locations of the nearest milk animal, the nearest residence, and the nearest garden of greater than 500 square feet producing fresh leafy vegetables in each of the 16 meteorological sectors within a distance of five miles of the plant.
Immediately following the collection of field data, in compliance with ODCM Control 4.2, a dosimetric analysis is performed to compare the census locations to the "Critical Receptor" identified in the ODCM. This Critical Receptor is the location that is used in the conservative Method I dose calculations found in the ODCM (i.e. the dose calculations done in compliance with ODCM Surveillance Requirement 3.4). If a Census location has a 20% greater potential dose than that of the Critical Receptor, this fact must be announced in the Semiannual Effluent Release Report for that period. A re-evaluation of which location to use as a Critical Receptor would also be done at that time. For the 2003 Census, no such location was identified.
Pursuant to ODCM Control 4.2, a dosimetric analysis is then performed, using site specific meteorological data, to determine which food product census locations would provide the optimal sampling locations. If any location has a 20% greater potential dose commitment than at a currently-sampled location, the new location is added to the routine environmental sampling program in replacement of the location with the lowest calculated dose (which is later eliminated from the program). For the 2003 Census, no such garden location was identified, and consequently no changes were mandated for the food product sampling program. Also, there were no milk animal locations that could provide milk samples for the REMP identified in the 2003 census.
The Land Use Census was carried out and completed between the dates of June 1 and October 1, as required. The results of the 2003 Land Use Census are included in this report in compliance with ODCM Surveillance Requirement 4.2. The locations identified during the Census may be found in Table A.1.

APPENDIX B - QUALITY ASSURANCE PROGRAM
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 B-2 Appendix B: QUALITY ASSURANCE PROGRAM The quality assurance program at the AREVA Framatome ANP Environmental Laboratory (E-LAB) 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 E-LAB 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 E-LAB on or before December 31, 2003.
Intralaboratory Quality Control Program The E-LAB 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.1 provides the summary of the process check results for January to December 2003. Of the 407 analyses, 98.0% passed the bias criteria and 100% of the 135 results evaluated for precision were acceptable. The E-LAB internal acceptance criteria are summarized at the end of Table B.1.
Third Party Cross Check Program The E-LAB participates in a third party cross check program managed by Analytics Inc. to satisfy the requirement of the Environmental Technical Specification/ODCM. The E-LAB 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 4th quarter 2002 through the 3rd quarter 2003 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 E-LAB Manual 100-Laboratory Quality Assurance Plan. This acceptance protocol is used for all inter-laboratory 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 E-LAB internal acceptance criteria are summarized at the end of Table B.1.
Yankee Rowe Station Annual Radiological Environmental Operating Report 2003 B-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 E-LAB 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 18 paired samples in 2003. The measurements evaluated include twenty-six gamma emitting radionuclides, H-3, 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 2003 program, 99.6% (482/484) of the measurements met the E-LAB internal acceptance criteria.
Environmental TLD Quality Assurance Program Performance documentation of the routine processing of the Panasonic environmental TLDs (thermoluminescent dosimeter) program at the E-LAB 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 2003 by E-LAB 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 E-LAB Internal Acceptance Criteria for bias (+/-20.1%) and precision (+/-12.8%). Third Party QC results are summarized below.
