40 Attachments Attachment 1 June 2007 Statistical Trend Analysis Data Sheets -SOCs Attachment 2 June 2007 Statistical Trend Analysis Data Sheets -TEDE LTP Groundwater Compliance Summary Report Vg Executive Summary Connecticut Yankee Haddam Neck Plant (HNP) has conducted groundwater monitoring in accordance with the groundwater monitoring plan implemented under the License Termination Plan (LTP) to support removal of non-independent spent fuel storage installation (ISFSI) areas impacted by groundwater contamination from the United States Nuclear Regulatory Commission (NRC) license (CYAPCO, 2006a). The LTP specifies a groundwater monitoring period of 18 months prior to removal of these areas from the license. The 18-month monitoring period started with the December 2005 groundwater sampling round and was completed with the June 2007 sampling round. Sampling on at least a quarterly basis has been conducted during the 18-month monitoring period. At the end of this period to meet NRC requirements, groundwater must exhibit the following conditions as established in the LTP (CYAPCO, 2006a): " Substance of Concern (SOC) concentrations that are stable or decreasing;

The cumulative dose resulting from residual soil, existing groundwater, and future groundwater does not exceed 25 mrem/ yr.This compliance summary report has been prepared for submittal with the Connecticut Yankee Atomic Power Company (CYAPCO) letter requesting release of the non-ISFSI* portion of the site from the NRC license based on the results of the 18 months of groundwater monitoring prior to license termination.

This report describes the existing groundwater conditions at HNP at the completion of the 18-month monitoring period.Based on the 18 months of groundwater monitoring (i.e., December 2005 through June 2007), the following observations support license termination:

1. The'plant-related SOCs detected in groundwater are tritium (H-3), strontium-90 (Sr-90), and cesium-137 (Cs-137).2. SOC concentrations at most monitored locations are exhibiting a stable or decreasing concentration trend. While most monitoring locations do have stable or decreasing concentration trends, six of 60 LTP monitoring wells (MW-105S, MW-107D, MW-107S, MW-109S, MW-120-4, and MW-125) exhibit an increasing trend for H-3 and five of the 60 LTP monitoring wells (MW-118A-5, MW-125, MW-124, MW-136D, and MW-137) are associated with an increasing trend for Sr-90. Although there is an increasing trend in a limited number of monitoring wells, CYAPCO believes that the intent of the LTP in this regard has been met for the following reasons: By fall 2006, remediation activities were completed in source areas (i.e. tank farm[2005], primary auxiliary building [PAB]-containment

[2005], and fuel building [fall 2006]) where significant residual soil radionuclide contamination was historically located. Due to the completed remediation efforts, no additional significant plumes of radionuclides are anticipated to be developed or migrate through the HNP site.LTP Groundwater Compliance Summary Report 1

Radionuclide concentrations in monitoring wells located within and adjacent to the former tank farm, spent fuel building, and PAB-containment areas have decreased substantially from the levels exhibited before, during, and immediately after remediation activities that were completed in 2005. Discrete plumes of radionuclide-contaminated groundwater were also developed during the more recent fuel building remediation in fall 2006 and are currently migrating through the HNP site." The magnitude and distribution of the discrete plumes of radionuclides originating from the fuel building and containment currently migrating through the site are well characterized due to the location of monitoring wells directly downgradient and adjacent to the former fuel building and containment source areas. The most recent discrete plume originated during remediation in the fuel building in September/

October of 2006. Reviewing the sample results from wells (in particular MW-137) adjacent to and directly downgradient of the fuel building and other downgradient wells, the following can be concluded:

a. Cesium-137, although detected in MW-137, has not been reported in downgradient monitoring wells, demonstrating that no significant migration of Cs-137 away from the fuel building has occurred.

Groundwater plumes of H-3 and Sr-90 associated with the fuel building and containment remedial activity have migrated downgradient from the fuel building and containment subsequent to the fall 2005 and fall 2006 remedial activities, respectively.

The different behavior for Cs-137 relative to H-3 and Sr-90 is related to the radionuclide-specific partition coefficients; Cs-137 has a stronger affinity for soil relative to H-3 and Sr-90.b. The maximum groundwater concentrations detected in any of the monitoring wells immediately downgradient of the fuel building since the fall of 2006 is 13,800 pCi/L for H-3 (MW-125, March 2007) and 13.1 pCi/L for Sr-90 (MW-125, March 2007). The TEDE dose from these two maximum concentrations totals 1.83 mrem/yr, 23% of the existing groundwater allowed dose. This dose is well below the 8 mrem/yr that has been allocated by CYAPCO for the existing groundwater dose component of Equation 5-1 of the LTP.c. The few monitoring wells with increasing trends are related to discrete plumes of H-3 and Sr-90 that are currently migrating through the HNP site.The discrete plumes are expected to dissipate and discharge to the Connecticut River during 2007.Although there may be some increases in H-3 or Sr-90 at downgradient monitoring wells in the near future related to the continued migration of discrete plumes of H-3 or Sr-90, the magnitudes of these increases are expected to correspond to a small fraction (i.e., less then 25%) of the allowable dose from the existing groundwater dose component of LTP Equation 5-1. Not all wells, therefore, need to show a stable or downward trend for it to be concluded that the concentrations in these downgradient monitoring wells will not rise to a level that approaches the allotted dose from the existing groundwater pathway. Based on this understanding, the total dose from all dose components of Equation 5-1 of the LTP will be below the unconditional release criterion of 25 mrem/yr.LTP Groundwater Compliance Summary Report 2

3. As of June 2007, the maximum cumulative total effective dose equivalent (TEDE) for all detected SOCs for the worst case monitoring well (MW-137) contributes 1.98 mrem/yr to the existing groundwater component of the cumulative dose estimate for the non-ISFSI areas of the HNP at the time of release of these areas from the NRC license. Most of this TEDE is from Cs-137 (70%), which has limited mobility in site groundwater.

4. The existing groundwater component of the cumulative dose for the non-ISFSI areas of the HNP at the time of release of these areas from the NRC license is less than the maximum allowable dose of 8 mrem/yr. Using the values given in No. 2 above for Sr-90 and H-3, radionuclides with mobility in groundwater, the worst-case sample result equates to 23% of the maximum dose allowed for the existing groundwater component of the LTP Compliance Equation 5-1. Compliance with this maximum ensures that the cumulative dose from all dose pathways is less than 25 mrem/yr TEDE.Based on the conditions observed during the 18-month license termination groundwater monitoring period, CYAPCO believes conditions for license termination for HNP groundwater are met for the non-ISFSI areas of the HNP at the time of release of these areas from the NRC license. While the cumulative TEDE is currently met at all monitoring wells, several monitoring wells do not currently exhibit a stable or downward trend. Based on the soil and bedrock remediation completed at HNP that has removed significant sources of SOCs and the site groundwater characterizati6n completed to date, Connecticut Yankee believes that these up-trending monitoring wells reflect passage of discrete plumes of H-3 and Sr-90 migrating across the site (see Section 2.0) resulting from disturbance during remediation of source materials, and that these discrete plumes will dissipate and discharge to the Connecticut River during 2007. Although some downgradient wells are exhibiting, or may in the future exhibit, upward trends and/or short-term increases in SOC concentration, the concentrations that are expected to result from those increased levels are predicted to be well below the dose allowed for existing groundwater.

Therefore, total dose from all dose components of Equation 5-1 of the LTP will be below the unconditional release criterion of 25 mrem/yr.LTP Groundwater Compliance Summary Report 3 1.0 Introduction This section describes the purpose, scope, and objectives of the Groundwater Compliance Summary Report and briefly summarizes the HNP LTP's use of groundwater monitoring data to document final status condition.

The introduction also includes a summary of the groundwater monitoring sampling events that were completed during the complete duration of the 18-month monitoring period.1.1 Report Purpose, Scope, and Objectives The purpose, scope, and objectives of this Groundwater Compliance Summary Report are as follows:* Purpose. The purpose of this document is to provide input to the Final Status Survey (FSS) report by presenting the groundwater compliance status within the framework of the HNP LTP at completion of the 18-month final status groundwater monitoring period.* Scope. The scope of this document is to evaluate groundwater conditions at HNP for the 18-month license termination monitoring period. Groundwater monitoring data for the time period of December 2005 through June 2007 are incorporated as part of this report, and complete the 18-month groundwater monitoring period.* Objectives.

The objectives for this report are to document the groundwater SOC status with respect to concentration temporal trends of detected SOCs in groundwater (identified as H-3, Sr-90, and Cs-137) over the 18 months of the LTP groundwater monitoring period (i.e., December 2005 through June 2007), and to calculate the maximum TEDE contribution from existing groundwater conditions as of June 2007.1.2 HNP License Termination Plan This section describes the LTP's integration of groundwater monitoring results into the final status dose estimate (i.e., current groundwater dose contribution).

The applicable metrics for SOCs in groundwater are summarized in Table 1-1. As identified in Table 1-1, the metrics summarized in this report include: " Maximum allowable TEDE contribution from existing groundwater compared to the target of 8 mrem/yr, and* SOC concentration trend in groundwater compared to the target of either stable or decreasing.

The stable or decreasing trend criterion was developed to ensure that radionuclide concentrations would not increase at some time in the future to levels in excess of the maximum allowable TEDE dose. The groundwater monitoring results for the radiological LTP Groundwater Compliance Summary Report 4 SOCs presented in this document will be incorporated into the letter requesting release of the non-ISFSI areas from the NRC license as the existing groundwater contribution to the post-closure dose equation is currently met (LTP Equation 5-1). The cumulative dose for the non-ISFSI areas of the HNP at the time of release of these areas from the NRC license will be compared to the NRC's 25 mrem/yr maximum allowable post-closure dose, and a preliminary FSS compliance statement will be prepared.

This document will be included as an attachment to the FSS final report.1.3 Groundwater Monitoring Activities A summary of monitoring events and related reports is presented in Table 1-2. The flow and consolidation of groundwater monitoring data are illustrated in Figure 1-1. As summarized in Figure 1-1 and Table 1-2, a total of seven quarterly sampling rounds and seven monthly reports were completed, along with three semi-annual reports during the 18-month groundwater monitoring period. This final LTP Groundwater Compliance Summary Report is issued at the completion of the 18-month groundwater monitoring period confirming and documenting the compliance criteria presented in the LP Groundwater Compliance Summary Report submitted following the March and April 2007 sampling events (months 15 and 16 of the 18-month groundwater monitoring period).LTP Groundwater Compliance Summary Report 5 2.0 Groundwater Monitoring Results This section summarizes the HNP groundwater monitoring results for plant-related SOCs during the monitoring period based on the data and results presented in the quarterly, semi-annual, and special sampling events data summaries and reports. A summary of groundwater monitoring reports that support the license termination is presented in Table 1-2.The results for SOCs for the second quarter (Q2) 2007 are included in Section 2.1, and the statistical trend analysis is summarized in Section 2.2 for the 18 months of monitoring data through, and including, the Q2 2007 sampling event.2.1 Summary of Groundwater Target Analyte Concentrations This subsection presents the most recent (i.e., Q2 2007) groundwater monitoring results and puts the current conditions in perspective of the applicable metrics (i.e., cumulative current groundwater TEDE contribution).

All 60 monitoring wells included in the 18-month monitoring program were sampled in June 2007 (Q2 2007) (Table 2-1). The June 2007 groundwater concentrations observed for H-3, Sr-90, and Cs-137 in the 60 monitoring wells included in the LTP monitoring program are presented in Table 2-1, along with the calculated TEDE contribution for each monitoring well. SOC results and TEDE contribution for Q1 2007 and April 2007 are also included in Table 2-1 for reference.

As many of the monitoring results for H-3, Sr-90, and Cs-137 are non-detect, the sample-specific minimum detectable concentration (MDC) is included in Table 2-1 where the reported concentration was below the MDC. MDCs are used for the concentration trend analysis (see Section 2.2), and per the LTP, only values greater then the MDC were used to calculate the TEDE for the monitoring wells (Table 2-1).During Q2 2007, H-3 concentrations ranged from non-detect to 14,000 pCi/L. Tritium concentrations are less than 4,000 pCi/L for all but four monitoring wells (MW-121A-4 (5,170 pCi/L), MW-119-5 (10,900 pCi/L), MW-110D (4,910 pCi/L), and MW-119-6 (14,000 pCi/L). These four monitoring wells are all located in downgradient areas of the site and indicate that significant plumes of H-3 are not currently present in the upgradient portion of HNP, which historically have been associated with source areas for the H-3 and other SOCs.Maximum H-3 TEDE contribution is 0.54 mrem/year from MW-119-6 (Table 2-1).Strontium-90 concentrations range from non-detect to 9.52 pCi/L for Q2 2007. The highest Sr-90 concentration reported for Q2 2007 is observed in MW-125 (9.52 pCi/L), which gives a TEDE of 0.95 mrem/yr. All other Sr-90 results are less than 4.5 pCi/L.Cesuim-137 was detected in only MW-137 at a concentration of 23.9 pCi/L (Table 2-1).Cesium -137 has been reported in MW-137 during the 18-month monitoring period ranging from 8.25 pCi/L (April 2006) to 126 pCi/L (October 2006). Detections of Cs-137 have been limited to the upgradient portion of the site close to historic source areas. The current LTP Groundwater Compliance Summary Report 6 Cs-137 concentration at MW-137 (23.9 pCi/L) corresponds to a TEDE of 1.39 mrem/yr (Table 2-1).In addition to the SOC groundwater monitoring results and single nuclide TEDE dose for the detected SOCs, Table 2-1 also includes the cumulative TEDE dose for all detected SOCs for each monitoring well included in the LTP monitoring program. Through Q2 2007, all but two monitoring wells (MW-125 and MW-137) have TEDE cumulative dose below 1.0 mrem/yr. The cumulative dose in June 2007 for MW-125 and MW-137 are calculated to be 1.07 and 1.98 mrem/yr, respectively; well below the 8 mrem/yr metric established for existing groundwater (Tables 1-1 and 2-1).2.2 Substances of Concern Trend Analysis This subsection presents the statistical trend analyses for the concentrations of SOCs detected during the complete duration of the 18-month license termination monitoring period and a discussion of the behavior of SOCs in HNP groundwater.

The trend analyses were conducted in the same manner as previously done for the semi-annual groundwater monitoring reports (CYAPCO, 2006c and 2007a). The analysis utilized Sens Slope Trend analysis, and all results indicating an upward trend were confirmed using Kendall-Mann Upward Trend analysis (USEPA, 1989 and 1992). The Sens Slope Trend analysis was performed using commercially available statistical analysis software (ChemStatTM).

For samples exhibiting non-detectable concentrations of SOCs, the sample-specific MDC was used as the sample value.The trend analyses include data for the license termination monitoring period only, starting with the December 2005 (Q4 2005) sampling event and including the June 2007 (Q2 2007)sampling event data. The trend analyses are summarized in Table 2-2, and the complete trend analyses results and time series graphs for each SOC and monitoring well are included as Attachment

1. For completeness, the previously calculated statistical trends identified for each nuclide in each monitoring well (as reported in previous semi-annual groundwater monitoring reports and the initial LTP Groundwater Compliance Summary Report) are also included in Table 2-2. In addition to the single SOC trends evaluated, the trend of cumulative TEDE for all three SOCs was also determined (Table 2-2).A total of 62 monitoring wells were evaluated for trend status. Two monitoring wells (MW-139 and MW-140) were included in the trend analysis, but are not part of the LTP monitoring plan. These two monitoring wells were installed at the request of Connecticut Department of Environmental Protection.

Of the 62 LTP monitoring wells evaluated for trend status, most of the results exhibited either stable or downward trends. Eight monitoring wells had upward trends determined for Sr-90 (MW-100S, MW-102D, MW-105S, MW-110S, MW-122S, MW-131D, MW-136S, and MW-139) and seven monitoring wells exhibit upward trends for Cs-137 (MW-100D, MW-103B, MW-106D, MW-118A-3, MW-119-5, MW-120-2, and MW-136D) where the upward trend is simply an artifact of variability in the sample-specific MDC (Table 2-2), as most of the results for SOCs in these monitoring wells were below radionuclide-specific MDC. Aside from the monitoring wells with LTP Groundwater Compliance Summary Report 7 upward trends attributed to non-detect concentrations, all other monitoring wells had stable or downward trends for Cs-137.Four of the 62 monitoring wells exhibited confirmed upward trends for H-3 (MW-107D, MW-107S, MW-109S, and MW-120-4), and four monitoring wells exhibited confirmed upward trends determined for Sr-90 (MW-118A-5, MW-124, MW-125, and MW-137)(Figures 2-1 and 2-2, respectively, and Table 2-2). Two monitoring wells (MW-105S and MW-125) had upward trends determined for H-3 that were not confirmed by the Kendall-Mann test, and one monitoring well (MW-136D) had an upward trend for Sr-90 that also was not confirmed with the Kendall-Mann analysis.

This indicates that the upward trends for these three monitoring wells are not as significant in a statistical sense as those trends confirmed with both Sens and Kendall-Mann analysis.Of the six monitoring wells with upward trends for H-3, five monitoring wells (MW-105S, MW-107D, MW-107S, MW-109S, and MW-120-4) had maximum H-3 concentrations less than 4,000 pCi/L (all but one monitoring well less than 2,570 pCi/L) with only a modest upward trend (Attachments).

The H-3 concentrations in these five monitoring wells are well below the target concentration for H-3. The small upward trend in these five monitoring wells does not appear to be a significant issue with regard to TEDE status, as the largest TEDE value associated with H-3 for these monitoring wells is less than 0.15 mrem/yr. The upward trend for H-3 in MW-125 has higher H-3 concentrations (up to 13,800 pCi/L; March 2007) and appears to be associated with a plume of H-3 that is migrating across the HNP site related to source removal activities (CYAPCO, 2006c). As shown in Figure 2-1, the H-3 concentration in MW-125 decreased substantially in April and June 2007 to H-3 levels less than 3,300 pCi/L indicating the plume is dissipating rapidly under normal groundwater flow conditions.

The TEDE dose due to H-3 in MW-125 in June 2007 equates to 0.13 mrem/yr or less then 2% of the allowable existing groundwater dose (Table 2-1).Five monitoring wells have upward trends determined for Sr-90. Two of the monitoring wells (MW-136D and MW-137) are installed adjacent to, and downgradient of, remediated former source areas (tank farm and fuel building, respectively) located in the upgradient portion of HNP, and three monitoring wells are located in the downgradient portion of the site (MW-118A-5, MW-125, and MW-124). The upward trends established for all five monitoring wells appear to be initiating decreasing trends, as the Q2 2007 Sr-90 concentrations are lower than the Q1 2007 concentrations in each well (Figure 2-2). The upward trends determined for MW-118A-5, MW-124, and MW-125 are consistent with a plume of Sr-90 migrating through the HNP site (CYAPCO, 2006c). The highest Sr-90 concentration in these five monitoring wells occurs in MW-125, and has decreased from 13.1 pCi/L in March 2007 to 9.52 pCi/L in June 2007 (Table 2-1 and Figure 2-2). The TEDE dose attributed to Sr-90 in MW-125 in June 2007 equates to 0.95 mrem/yr per year or less then 12% of the allowable existing groundwater dose (Table 2-1).As cumulative TEDE is one of the key metrics for license termination, the trend of cumulative TEDE was also evaluated for all monitoring wells included in the 18-month monitoring plan through June 2007 (Table 2-2). The complete trend analysis results are included in Attachment

2. Similar to the trends established for individual SOCs, most monitoring wells had either stable or decreasing trends (Table 2-2). A total of seven monitoring wells (MW-107D, MW-109S, MW-118A-5, MW-120-4, MW-124, MW-125, and LTP Groundwater Compliance Summary Report 8 MW-131S) had upward trends identified for cumulative TEDE based on the most recent measurements, all but two (MW-109S and MW-131S) confirmed by the Kendall-Mann test.Upward trends in TEDE are a direct result of upward trends discussed above for SOCs Sr-90 and H-3. The variation of TEDE through time for the seven monitoring wells is shown in Figure 2-3. Most of the monitoring wells have cumulative TEDE less than 1.0, and the greatest cumulative TEDE value identified in the seven monitoring wells is 1.83 mrem/yr (MW-125 March 2007, Table 2-1 and Figure 2-3). The TEDE dose from this well subsequently decreased to 1.07 mrem/yr in June 2007 (Table 2-1). The maximum total TEDE value observed in MW-125 is well below the 8.0 mrem/yr established for existing groundwater (maximum of 22.5% in March of 2007). As shown in Figure 2-3, all of the seven monitoring wells demonstrated the initiation of decreasing TEDE values as the June 2007 TEDE values were lower than those established for March 2007 (Table 2-1).As discussed above, the presence of monitoring wells with increasing TEDE is related to plumes of H-3 and Sr-90 that are migrating through the HNP site (CYAPCO, 2006c). The hydrogeologic conceptual model for HNP identifies a shallow, unconfined aquifer that occurs within unconsolidated sands and the upper, fractured portion of bedrock within the general footprint of the HNP industrial area, and a confined aquifer that occurs in the deeper bedrock. Groundwater in both aquifers exhibits recharge in the upgradient portion of the site with groundwater flow in both aquifers towards the Connecticut River where both aquifers discharge to the river (Figures 2-4 and 2-5). Radionuclide contamination (H-3, Sr-90, and Cs-137) occurs in both aquifers with historic source areas associated with the former tank farm, PAB, containment, and the fuel building all located in the upgradient portion of the HNP site. Tritium is present in both aquifers, while Sr-90 and Cs-137 are primarily distributed in the shallow, unconfined aquifer and the shallowest portion of the confined aquifer. The general radionuclide distribution is consistent with the soil/rock-groundwater partitioning behavior exhibited by Sr-90, Cs-137, and H-3. Both Sr-90 and Cs-137 exhibit substantial partition coefficients, while H-3, moving as tritiated water, does not partition to the solid phase. The partitioning behavior of the SOCs limits the migration of Sr-90 and Cs-137 relative to the highly mobile H-3.Prior to 2005, the containment foundation mat dewatering sump (mat sump) was in operation, which exerted a hydraulic control on groundwater flow in both aquifers.

In addition, active dewatering to support demolition and soil remediation gave rise to a groundwater capture zone in the central industrial area of HNP. Since the mat sump and the demolition dewatering system were shut down in mid-2005, groundwater levels have established a continuous gradient from the upgradient portion of the site to the Connecticut River. During the time of the historical mat sump operation, much of the radionuclide-contaminated groundwater in the upgradient areas of HNP was captured by the sump and subsequently discharged to the Connecticut River via the plant National Pollutant Discharge Elimination System (NPDES) permitted outfall system.Substantial soil and bedrock remediation has occurred at HNP. The remedial efforts were focused in soils and shallow bedrock within source areas located in the upgradient portion of the site including the PAB-containment area (2005), tank farm (2005), and fuel building (fall 2006). The PAB- containment area and tank farm remedial efforts occurred prior to the mat sump closure and during dewatering efforts in the upgradient portion of HNP in 2005.Both the mat sump and the dewatering activities acted to minimize migration of LTP Groundwater Compliance Summary Report 9 radionuclide-contaminated groundwater that may have been created during the remedial activities.

Subsequent to the PAB and tank farm remedial efforts, SOCs adjacent to and downgradient of these areas have seen significant reductions in SOC concentration levels (CYAPCO, 2006a and CYAPCO, 2006c).The fuel building remedial effort occurred in fall 2006 after the mat sump closure and did not include significant dewatering activities.

As a result, it appears that a pulse of radionuclide contamination was released during the fuel building soil remediation.

The groundwater impacts associated with the fuel building remediation are shown in Figure 2-6 where H-3 and Sr-90 groundwater concentrations are plotted versus sample date for MW-137. Well MW-137 is located adjacent to and directly downgradient of the fuel building (Figures 2-4 and 2-5). As shown in Figure 2-6, a substantial increase in H-3 is observed coincident with the fuel building remedial effort. Tritium in MW-137 is shown to increase from values near 1,000 pCi/L to a maximum value of 11,900 pCi/L in the September 2006 quarterly sampling round. Also shown in Figure 2-6 is a substantial increase in Sr-90 that occurred in MW-137 approximately three months later. Both of the observed concentration spikes are believed to be related to the fuel building remedial efforts. The lag in time associated with the Sr-90 concentration spike is a function of the retardation experienced by Sr-90 due to the significantly larger soil-water partition coefficient associated with Sr-90 relative to the non-retarded H-3.The slugs of H-3 and Sr-90 contaminated groundwater that were released during the fuel building remediation in fall 2006 are currently migrating across the HNP site, and are responsible for some of the current upward trends observed in the HNP monitoring wells.An example of the H-3 slug migration is illustrated in Figure 2-7 where H-3 concentrations are plotted versus sample date for MW-137, MW-106S, and MW-125. Well MW-137 is upgradient of MW-106S, and MW-125 is downgradient of MW-106S (Figures 2-4 and 2-5).Thus, groundwater generally flows from the vicinity of MW-137 past MW-106S toward MW-125. The peak H-3 concentration observed for MW-137 occurred in early September, followed by the peak value in MW-106S that occurred in the October-November 2006 timeframe (Figure 2-7). The H-3 concentration in the downgradient MW-125 begins to increase in December 2006 and by April and June 2007 has significantly decreased (Figure 2-7). The duration of the slug appears to be approximately six months as observed in all three monitoring wells (Figure 2-7).The impact of the slug of H-3 is more significant for MW-125 than that observed in MW-106S, as the peak H-3 concentration observed in MW-125 during March 2007 (13,800 pCi/L) is similar to that observed in MW-137 in September 2006 (11, 900 pCi/L).The peak H-3 value observed for MW-106S in fall 2006 was 5,260 pCi/L. This is due to the fact that MW-125 is more directly on the downgradient groundwater flow path from MW-137 and the fuel building relative to MW-106S (Figures 2-4 and 2-5). The slug of H-3 contaminated groundwater could be expected to impact monitoring wells downgradient of MW-125 during summer 2007 as it migrates through the downgradient portion of the site prior to discharge to the discharge canal and/or Connecticut River.A similar scenario is also anticipated for Sr-90. The Sr-90 released during the fuel building remedial effort is expected to migrate through the HNP site, but at a retarded rate relative to that observed for H-3. Figure 2-8 shows Sr-90 groundwater concentrations versus sample date for MW-137, MW-106S, and MW-125. The slug of Sr-90 released from the fuel building LTP Groundwater Compliance Summary Report 10 remediation passed through MW-137 in the December 2006-January 2007 time period and began to impact MW-106S in March-April 2007 (Figure 2-8), but at a lower concentration similar to the behavior of H-3 in MW-106S. While MW-125 is shown to have increasing Sr-90 during June 2006 through March 2007, the slug of Sr-90 ihat originated from the fuel building remediation in December 2006 has likely not reached MW-125 as of June 2007. The Sr-90-contaminated slug of groundwater associated with the fuel building remediation is expected to impact MW-125 in the summer-fall 2007 time period and is predicted to have a peak concentration in the range of that observed for MW-137 in December 2006 (9.72 pCi/L).In addition to the Sr-90 increase experienced by MW-125 during early 2007, an earlier spike in Sr-90 also occurred in MW-106S during late August/early September 2006 (Figure 2-8).Sr-90 in MW-106S increased to 13.1 pCi/L in the third quarter 2006 and decreased to less than 2 pCi/L over a six-month period (Figure 2-8). A similar spike in Sr-90 also occurs in MW-125 approximately six months later, but no earlier significant increase in Sr-90 prior to August/September 2006 is observed for MW-137 (Figure 2-8). This suggests that the source for the slug of Sr-90 that impacted MW-106S and MW-125 during early September 2006 and March 2007, respectively, was located downgradient of MW-137, but upgradient of both MW-106S and MW-125. Likewise, the Sr-90 release would have occurred at least three months prior to the early September 2006 time period, based on the delayed presence of Sr-90 observed in MW-137 that was associated with the fuel building remediation.

During fall 2005, focused soil excavations within the annular space between the containment dome and surrounding bedrock excavation along the eastern, southern, and southwestern portions of containment were conducted to remove Sr-90 -contaminated soil (Figure 2-9).Most of this portion of the containment dome is downgradient of MW-137, but upgradient of both MW-106S and MW-125 (Figures 2-4 and 2-5). Based on the groundwater flow direction indicated in Figure 2-4, a plume of Sr-90 originating along the southern portion of containment would flow through both MW-106S and MW-125, but would have originated downgradient of MW-137. During the focused soil removal around containment, the mat sump was utilized for a period of time to minimize impacts to groundwater.

The use of the mat sump, the approximate 100-foot distance from containment, and the retardation related to soil-water partitioning experienced for Sr-90 delayed the appearance of Sr-90 in MW-106S until the April-June 2006 time period, and the peak concentration associated with the slug of Sr-90 was observed in September 2006 (Figure 2-8). This slug of Sr-90 impacted MW-125 approximately six months later in March 2007 when 13.1 pCi/L was reported (Figure 2-8).Based on the decrease in Sr-90 to 9.52 pCi/L in MW-125 in June 2007 from the peak concentration of 13.1 pCi/L reported in March 2007, this Sr-90 plume appears to be migrating through the southern portion of the HNP site, and will ultimately discharge to either the discharge canal or Connecticut River (Figure 2-4).The peak concentration of Sr-90 that will be observed in downgradient wells in the future is expected to be at or below the observed upgradient peak concentrations due to the attenuation of Sr-90 in the intervening unconsolidated formation and reactive fracture fill in shallow bedrock and processes of dilution and dispersion related to advective groundwater flow. The peak Sr-90 concentration in MW-137 associated with the fuel building remediation was 9.72 pCi/L (December 2006), while the peak Sr-90 value associated with the focused containment remediation was 13.1 pCi/L (MW-106S, September 2006 and LTP Groundwater Compliance Summary Report 11 MW-125 March 2007). These concentrations equate to TEDE doses of 0.97 mrem/yr and 1.3 mrem/yr, respectively.

In general, H-3 has decreased in most of the monitoring wells in the upgradient portion of HNP in both the unconfined and confined aquifers.

This is due to the substantial source remediation that has occurred in the tank farm, PAB-containment area, and most recently the fuel building, and the relatively rapid migration of the non-retarded H-3 relative to Sr-90. As of June 2007, all upgradient monitoring wells (i.e., monitoring wells upgradient of MW-125) have H-3 concentrations less than 4,000 pCi/L. The recent semi-annual groundwater monitoring report (Q3-Q4 2006) documented a slug of H-3-contaminated groundwater that was present in the downgradient portion of the deeper, confined aquifer during Q3 and Q4 2006 (see Figures 6-6 and 6-14 in the Semi-Annual Groundwater Monitoring Report). This is consistent with the low concentration distribution of H-3 observed in the upgradient monitoring wells through June 2007 (CYAPCO, 2007). The peak H-3 concentration in upgradient monitoring well MW-137 was 11,900 pCi/L (September 2006), while the current H-3 concentration in MW-137 is 3,920 pCi/L (June 2007). These H-3 concentrations equate to TEDE doses of 0.46 mrem/yr and 0.15 mrem/yr, respectively.

While H-3 currently appears to be focused in the more downgradient portions of the site, Sr-90 is still present in the more upgradient portion of HNP, and will take longer to migrate through the site. Increases in Sr-90 are expected to occur in MW-125 and potentially other downgradient monitoring wells during 2007. The maximum H-3 and Sr-90 groundwater concentrations that are experienced in the upcoming quarters should be bounded by concentrations already observed in upgradient monitoring wells. This is a function of the location of historic source areas in the upgradient area of HNP, the soil and bedrock remediation completed to date in those areas, partial attenuation of Sr-90 on aquifer materials, and processes of dilution and dispersion related to advective groundwater flow.Although there may be some increases in H-3 or Sr-90 in downgradient monitoring wells in subsequent sampling rounds related to the continued migration of discrete plumes of H-3 and/or Sr-90 associated with recent remediation, the magnitude of these increases is expected to correspond to a small fraction (i.e., less then 25%) of the allowable dose from the existing groundwater dose component of LTP Equation 5-1 (8.0 mrem/yr).As previously discussed, H-3 and Sr-90 are passing through the site at different rates. If the bounding concentrations given above for the upgradient wells (i.e., highest H-3 and Sr-90 concentrations directly downgradient of fuel building in MW-137) were to occur in a downgradient well at some time in the future, the maxim um TEDE contribution would be 1.42 mrem/yr or 18% of the allowable dose for existing groundwater.

Even with this conservative assumption, the TEDE is well below the 8.0 mrem/yr established in the LTP.Therefore, not all wells need to show a stable or downward trend for it to be concluded that the concentrations in these downgradient monitoring wells will not rise to a level that approaches the allotted dose of 8.0 mrem/yr.LTP Groundwater Compliance Summary Report 12 3.0 Conclusions Based on the 18 months of groundwater monitoring (i.e., December 2005 through June 2007)the following observations support license termination:

1. The plant-related SOCs detected in groundwater are H-3, Sr-90, and Cs-137.2. Most monitoring locations do have stable or decreasing concentration trends; six monitoring wells (MW-105S, MW-107D, MW-107S, MW-109S, MW-120-4, and MW-125)exhibit an increasing trend for H-3 and five monitoring wells (MW-118A-5, MW-125, MW-124, MW-136D, and MW-137) are associated with an increasing trend for Sr-90.The increasing trends are related to discrete plumes of H-3 and Sr-90 that are currently migrating through the HNP site resulting from source removal remedial actions conducted around containment in fall 2005 and at the fuel building in the fall of 2006.The discrete plumes are expected to dissipate and discharge to the Connecticut River during 2007. While all monitoring wells do not currently exhibit stable or decreasing trends for H-3 or Sr-90, the radionuclide concentrations within the plumes have TEDE values well below the maximum allowable dose of 8 mrem/yr (bounding concentrations sum to 23% of maximum allowable dose), and source remediation at HNP has minimized the potential for significant groundwater plumes to be created in the future.3. Through June 2007, the maximum cumulative TEDE for all detected SOCs for the worst case monitoring well contributes 1.98 mrem/yr to the existing groundwater component of the cumulative dose estimate for the non-ISFSI areas of the HNP at the time of release of these areas from the NRC license.4. The existing groundwater component of the cumulative dose for the non-ISFSI areas of the HNP at the time of release of these areas from the NRC license is 25% of the maximum allowable dose of 8 mrem/yr. Compliance with this maximum ensures that the cumulative dose from all dose pathways is less than 25 mrem/yr TEDE.Based on the conditions observed during the 18-month license termination groundwater monitoring period, the license termination conditions for HNP groundwater are believed to have been met for the non-ISFSI areas of the HNP at the time of release of these areas from the NRC license. The existing groundwater TEDE dose is well below the existing groundwater criterion of 8.0 mrem/yr at all monitoring locations.

Several monitoring wells have increasing trends for H-3 and Sr-90. The increasing trends are related to the migration of discrete plumes of SOCs that were associated with soil remediation/

source removal conducted around containment in fall 2005 and in the fuel building area in fall 2006. These discrete plumes are expected to migrate through the HNP site during 2007. The dose contribution resulting from SOC concentrations in groundwater at HNP is expected to remain well below the dose allowed for existing groundwater although some downgradient wells are or may in the future exhibit short term increases in concentration and/or upward trends. Potential future SOC groundwater concentrations in downgradient wells are believed to be bounded by concentrations already observed in upgradient wells. SOCs will be diluted and dispersed related to advective groundwater flow, and Sr-90 will exhibit LTP Groundwater Compliance Summary Report 13 partial attenuation as it moves through aquifer sediments.

Based on the observed SOC concentrations in upgradient monitoring wells, any increase in SOC concentration for the downgradient monitoring wells is expected to be less than 25% of the existing groundwater TEDE of 8 mrem/yr. The total dose, therefore, from all dose components of Equation 5-1 of the LTP will be below the unconditional release criterion of 25 mrem/yr. Although results of the last sampling effort reveal several monitoring wells that do not meet the criterion of a stable or decreasing trend, the cumulative data effectively identifies the transient nature of the increasing trends and supports the conclusion that the magnitude of potential future increases in downgradient wells will not exceed the groundwater TEDE limit of 8 mrem/yr.Based on this conclusion, CYAPCO requests concurrence that the results of the 18-month period of groundwater monitoring program successfully demonstrates this site can be removed under the LTP.LTP Groundwater Compliance Summary Report 14 4.0 References CYAPCO, 2006a.
