Dear-Mr.-Tosch:
QUARTERLY REMEDIAL ACTION PROGRESS REPORT, SECOND QUARTER 2005 PSEG NUCLEAR, LLC, SALEM GENERATING STATION PSEG Services Corporation (PSEG) has prepared this Quarterly Remedial Action Progress Report (RAPR) to provide a summary of groundwater remediation activities conducted since the submission of the previous RAPR in May 2005 at the PSEG Nuclear, LLC Salem Generating Station (the Station). The Station is located on Artificial Island in Hancock's Bridge, Salem County, New Jersey. The Station location and layout are presented on Figures 1 and 2, respectively. Groundwater remediation activities are being conducted to address tritium detected in shallow groundwater adjacent to and south of Salem Unit 1.
Project Background In April 2004, a Remedial Investigation Report (RIR) was submitted to the New Jersey Department of Environmental Protection Bureau of Nuclear Engineering (NJDEP-BNE) presenting the details and results of groundwater investigation activities that were conducted following the discovery of tritium in groundwater adjacent to Salem Unit 1.
The results of the remedial investigation indicated that the source of tritium detected in groundwater was the Spent Fuel Pool, the tritium release to the environment has been stopped, and that tritium has not migrated to the property boundary above the New Jersey Groundwater Quality Criterion (GWQC) for tritium.
KJ -
Mr. Kent Tosch 2 August 9, 2005 The remedial investigation produced a comprehensive body of knowledge that was E-) used as the basis for developing a remedial action strategy designed to hydraulically contain the further migration of tritium in groundwater and to reduce the concentration of tritium in groundwater. In July 2004, a Remedial Action Work Plan (RAWP) was prepared and submitted to the NJDEP-BNE presenting the proposed remedial action for achieving these objectives. The RAWP, which proposed the operation of a groundwater extraction system, was approved by the NJDEP in November 2004. In April 2004, prior to the submittal of the RAWP, PSEG conducted a groundwater extraction pilot study designed to demonstrate the effectiveness of groundwater extraction for achieving the remedial objectives. The pilot study proved to be effective and a full-scale groundwater extraction system was subsequently installed.
The following sections present the details and results of activities conducted since the submittal of the May 2005 RAPR, document the progress of remedial actions conducted to date, and provide a discussion of upcoming activities projected for the next reporting period.
Continued Groundwater Monitoring Groundwater monitoring activities consist of the periodic collection of groundwater samples from the 36 Station monitoring wells. A summary of the Station-mdon-itdlrnTWellI details are included in Table I and their locations are presented on Figure 2. Pursuant to the schedule presented in the previous RAPR and subsequent conversations with the NJDEP, the monitoring wells are sampled according to an adaptively managed schedule whereby wells that have been established to have tritium levels that do not exceed ambient levels (including the Vincentown Wells) are sampled semi-annually, wells screened within the shallow water bearing unit but located such that tritium would not be reasonably expected to migrate to them are monitored on a quarterly basis; and, wells that monitor groundwater quality within the groundwater extraction zone and at the property boundary are monitored on a monthly basis. Groundwater monitoring at Well AQ, which was installed within a cofferdam cell, has ceased. Additionally Wells AP and Z have been sampled at a temporarily increased frequency (biweekly) to facilitate further evaluation of the increased concentrations of tritium observed in groundwater samples collected from the AP well in February 2005. The sampling program is designed to ensure representative data are collected that meet the objectives of the investigation and provide the information necessary to evaluate plume migration and capture.
Groundwater samples are submitted to Salem Chemistry for analysis and samples indicating tritium concentrations less than 20,000 picocuries per liter (pCiIL) are sent to Maplewood Testing Services for more refined analysis. Historically, groundwater samples were analyzed for tritium, major cations and anions (e.g., sodium and boron),
and gamma-emitting isotopes. Boron monitoring has ceased as was stated in the last RAPR (Q1 2005). The large volume of analytical data collected to date indicates that plant related gamma-emitting isotopes have not been detected in groundwater samples
Mr. Kent Tosch 3 August 9, 2005 collected during the groundwater investigation, and thus have not migrated any tJ significant distance beyond the seismic gap.
An update of analytical results for groundwater samples from the Site monitoring wells through June 2005 are summarized in Table 2 and are presented on Figure 3. Historic analytical results were presented in the RIR and previous RAPRs. Included on Figure 3 are the extent of tritium in groundwater at the completion of the remedial investigation (Baseline Plume), which was completed in April 2004, the extent of tritium in groundwater in December 2004 in the eighth month of the pilot groundwater remediation activities, and the current extent of tritium in groundwater. Based on a review of the three maps, it is apparent that the mass of tritium in groundwater has been reduced by the remedial efforts completed to date. Details regarding these activities are included in this report.
Specific details regarding the analytical results for the groundwater samples are presented in the following sections. The analytical results for the monitoring wells were evaluated based on the water-bearing zone in which the monitoring wells are screened.
The three primary water-bearing units being investigated beneath the Station are: 1) the Vincentown Formation; 2) the shallow, water-bearing unit within the limits of the cofferdam; and, 3) the shallow, water-bearing unit outside of the limits of the cofferdam.
Tritium Analytical Results for the Vincentown Formation Groundwater quality for wells screened in the Vincentown Formation, which consist of Well K, Well L, Well P, Well Q, and Well V, is currently monitored on a quarterly or semi-annual basis. Groundwater samples collected from these wells are analyzed for tritium and gamma-emitting isotopes. Analytical results of groundwater samples collected from Wells P and Q indicate concentrations of tritium below the laboratory detection limits. Tritium has only been detected at a concentration above laboratory detection limits once (July 2004) in groundwater from Well L; however, the tritium concentration was well below the New Jersey Groundwater Quality Criteria. Analytical results of groundwater samples collected from Wells V and K have never indicated tritium concentrations greater than 402 pCi/L and 1,170 pCi/L, respectively and both are near their respective minima.
Analytical results of groundwater samples collected from the monitoring wells screened in the Vincentown Formation indicate that the release of water from the Spent Fuel Pool has not migrated beyond the shallow water-bearing unit.
Tritium Analytical Results for Wells Installed Within the Limits of the Cofferdam Wells screened in the shallow, water-bearing unit within the limits of the cofferdam consist of Well M, Well N, Well 0, Well R, Well AC, Well AE, Well Al, Well AM, Well AN, and Well AO. As expected, based upon their location relative to the Salem Unit 1
Mr. Kent Tosch 4 August 9, 2005 seismic gap, analytical results of groundwater samples collected from these wells indicate the highest tritium concentrations in groundwater at the Station. Well AC is located directly southeast of the Salem Unit I seismic gap and has indicated tritium concentrations as high as 15,000,000 pCi/L. Analytical results of more recent groundwater samples collected from this well indicate tritium concentrations of approximately 26,300 pCi/L, just slightly above the NJDEP GWQC for tritium. The decrease in tritium concentrations at Well AC is further confirmation that the release of water from the Spent Fuel Pool has been stopped and the operation of the seismic gap drain and the groundwater extraction system (discussed later in the report) are effectively reducing concentrations of tritium in groundwater.
Trend charts of historic tritium concentration for select wells are presented on Figure 4.
Analytical trends for wells screened within this unit exhibiting tritium concentrations above NJDEP GWQC continue to show generally decreasing trends. This provides an indication that tritium concentrations are decreasing within this unit since the elimination of the source through the operation of the Unit-1 seismic gap drain and operation of the groundwater extraction system. As expected, some wells completed within the cofferdam have shown increasing and indefinite trends as a result of the changes to the groundwater flow field caused by the start-up of the full-scale system. It is expected that these trends will stabilize and become decreasing as seen in many of the pumping Tritium Analytical Results for Wells Installed Beyond the Limits of the Cofferdam The wells installed in the shallow, water-bearing unit beyond the limits of the cofferdam are Well S, Well T, Well U, Well W, Well Y, Well Z, Well AA, Well AB, Well AD, Well AF, Well AG (Shallow and Deep), Well AH (Shallow and Deep), Well AJ, Well AL, Well AP, Well AQ, Well AR, Well AS, and Well AT. These wells are screened either just above the clay confining unit that separates the shallow water-bearing unit from the Vincentown Formation, or in the interval indicating the highest tritium concentrations at the time of the Supplemental Investigation completed in August 2003. Note that one anomalous detection occurred in Well T in February which to date has not been repeated. It is believed that this detection is the result of laboratory cross-contamination. Additionally as shown on Figure 4 an increased concentration of tritium was detected in Well AP in March, and confirmed by subsequent samples. PSEG responded by reactivating the mobile groundwater extraction unit to spot remediate the area. This approach has proved effective in decreasing concentrations at Well AP. It is believed that the increased concentrations are a result of the differential pumping rates between the wells near the edge of the cofferdam (Wells S and AD) and the wells closer to the river (Wells AS and AT). The result has been a more southerly groundwater flow direction than had been anticipated. Contingency plans were developed to allow for the connection of Wells AP and W to the system in the event that flow towards the river became an issue of concern. Additionally Well Z has been monitored at an increased frequency during the evaluation of this issue. Table 3 presents the planned monitoring schedule thorough August of 2005.
Mr. Kent Tosch 5 August 9, 2005
\.. The trends for tritium concentrations for wells screened in the shallow, water-bearing unit. indicate that groundwater extraction associated with the groundwater extraction system has demonstrated the ability to achieve the remedial action objectives (i.e.,
reduce the mass of tritium in groundwater). The current distribution of tritium in groundwater (June 2005) is presented on Figure 3, along with the distribution of tritium prior to the initiation of the pilot study (March 2004) and in December 2004 during the eighth month of the pilot study. As shown on Figure 3, the mass of tritium in groundwater has continued to decrease through the operation of the groundwater extraction pilot study system and operation of the full-scale system.
Groundwater Extraction Inaccordance with the RAWP, groundwater extraction activities completed to date consisted of the operation of the pilot-study from April 26, 2004 to February 11, 2005 and operation of the full scale system from February 16, 2005 to present.
Full-Scale System Based on the results of the pilot study, a full-scale system was designed and installed.
The objectives of the full-scale system, are thefoll6oing: 1I)-to-minfrtaiit-hydraulic containment of the tritium plume; and, 2) to reduce tritium concentrations in groundwater.
The present full-scale system consists of the extraction of groundwater from Wells S, AB, AD, AJ, AN, AS and AT. Well AO continues to be secured to prevent interference with diesel fuel oil recovery operations and Well S has been operating intermittently as a result of its low yield. Groundwater extracted from the wells is processed in accordance with the Station's United States Nuclear Regulatory Commission (USNRC) license and plant procedures.
The full scale system is periodically shut down to service the integrators used to monitor system output. Ten such shut downs occurred during this reporting period resulting in less than 15 days of system down time.
Mobile Groundwater Extraction Unit In response to increased concentrations of tritium detected in well AP beginning in March 2005, the Mobile Groundwater Extraction unit was reactivated to recover groundwater from Well AP. The effectiveness of the use of the Mobile Groundwater Extraction Unit was evaluated through increased monitoring of groundwater at this well.
In the event that more frequent pumping is required from Well AP provisions were made in the design of the system to allow Well AP to be connected to the groundwater extraction system.
Mr. Kent Tosch 6 August 9, 2005 Following extraction, groundwater held in the mobile unit is re-circulated for K.) approximately two hours and sampled for characterization. Following characterization, the groundwater is disposed of in accordance with the Station's United States Nuclear Regulatory Commission (USNRC) license and plant procedures. Table 4 presents the details of each mobile system discharge cycle.
Reactivation of the mobile unit was effective in removing the groundwater with elevated concentrations of tritium from Well AP. As of June 21 the concentration had decreased from 106,000 pCi/L (June 6) to 46,400 pCi/L and, as of July 6 the concentration had decreased to below Salem Chemistry's analytical detection limits.
Total System Effluent Data and Evaluation The full scale system became operational on February 16, 2005. The system operated in various configurations as part of the shakedown process for approximately the first month. The full scale system discharges continuously in accordance with the Station's NRC permit allowing the full-scale system to be more effective and efficient than the pilot-scale system. As of June 30, 2005, the full scale system has recovered greater than 1.4 million gallons of groundwater. This is equivalent to an average recovery rate
-of.just-over 10.7_gallons-per minute or nearly 15 times the recharge rate for the extraction area (assumed to be 0.7 gallons per minute). Table 5 presents a summary of the full-scale system discharges through June 30, 2005.
By Water-Level Data and Evaluation Water-level measurements from the extraction and select observation wells have been monitored to demonstrate that the full-scale groundwater extraction system has hydraulically contained the migration of tritium in groundwater. To demonstrate this effectiveness, water levels are periodically collected and evaluated.
Figures 5 presents the groundwater surface contours on March 19, 2004 under static (non-pumping) conditions prior to the start of the pilot study. The groundwater flow under static conditions is in a generally southwesterly direction towards the Delaware River. Figure 6 presents the groundwater surface contours on July 7, 2005 during operation of the full scale groundwater extraction system. From Figure 6 it is apparent that the system is effectively controlling the plume by hydraulically containing the area where elevated tritium in groundwater exists.
Cumulative Curies Removed The various groundwater recovery activities conducted to date have been successful in recovering tritium from groundwater at and down gradient of the Salem Unit-1 seismic gap.
Mr. Kent Tosch 7 August 9, 2005 Full-Scale System As summarized in Table 5, approximately 0.41 curies of tritium have been recovered from the operation of the groundwater extraction full-scale system through June 30, 2005. Figure 7 summarizes the results of the groundwater remediation activities conducted using the well field. As of June 30, 2005 greater than 1.2 curies had been removed by the well field. The effectiveness is emphasized by the decrease and stabilization in system effluent concentrations since the activation of the full scale system in February of 2005. System effluent concentrations are presently around 51,000 pCi/L.
Other Remedial Actions In addition to the operation of the groundwater extraction systems, seismic gap drains in Salem Unit 1 and Unit 2 have been have been used to drain the water from these gaps.
The following sections provide a brief overview of these activities.
Operation of the Seismic Gap Drain
-The-permanent-drains-installed-in-the-Salem-Unit-I-and seismic -gaps -facilitate -the periodic collection and characterization of groundwater accumulating in the seismic gaps. The operation of these gap drains creates an inward gradient towards the gaps facilitating the recovery of water from a low accessibility area. To date, periodic operation of the seismic gap drain in Unit 1 has resulted in the recovery of approximately 23,000 gallons of tritiated water. As summarized in Table 7, the concentrations of tritium in the water recovered in the Unit 1 drain have been significantly higher than those detected in groundwater samples collected from Well AC and Well AM located to the southeast and southwest of the seismic gap, respectively.
The Unit 1 seismic gap drain is effectively containing residual Spent Fuel Pool water in the seismic gap, and will ultimately result in the reduction of tritium concentrations in groundwater adjacent to the seismic gap. As shown on Figure 13, a total of approximately 3.5 curies of tritium has been recovered from the operation of the Unit 1 seismic gap drain through June 30, 2005. Concentrations have become more stable since the activation of the full scale groundwater extraction system and are presently in on the order of 37,000,000 pCi/L, down from a peak of greater than 100,000,000 pCi/L.
Analytical results for water samples collected from the Unit 2 seismic gap drain do not indicate concentrations of constituents that would indicate a similar release occurred from the Unit 2 Spent Fuel Pool. As evidenced by the lack of short-lived gamma-emitting isotopes, samples collected from Unit 1 gap drain do not indicate an ongoing or recent release of spent fuel pool water, Unit 2 gap drain water contains no plant gamma activity. Water samples will be obtained from both gap drains on a periodic basis to evaluate the water that has accumulated in the respective seismic gaps, and to provide a backup warning of a potential release of spent fuel pool water, with the primary method still remaining the monitoring of the SFP tell-tale drains.
Mr. Kent Tosch 8 August 9, 2005 Upcoming Activities Activities projected for the Third Quarter of 2005 (July through September) include the following:
- Refine the procedures and protocols as necessary to adaptively manage the operation and sampling of the full scale groundwater extraction system;
- Periodic download of data from permanent data-logging pressure transducers installed in 14 wells throughout the area to demonstrate that groundwater extraction is effectively maintaining hydraulic control;
- Continued groundwater monitoring activities;
- Update the groundwater monitoring program;
- Continued operation and evaluation of data obtained through the full-scale groundwater extraction system; and,
- Submittal of the RAPR for the third quarter of 2005. The RAPR will document the progress of the full-scale groundwater extraction system.
