Dear Mr. Tosch:

QUARTERLY REMEDIAL ACTION PROGRESS REPORT, THIRD 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 August 2005 at the PSEG Nuclear, LLC Salem Generating Station (the Station). We are transmitting 3 copies of this report to you.

Continued Groundwater Monitoring Groundwater samples continue to be collected from the monitoring well network according to the published schedule. Figure 1 presents the recent groundwater analytical results.

In general, tritium concentrations in groundwater samples continue to be stable or slightly decreasing. Observed Increased concentrations at Well AC and Well M are believed to be a result of infrequent rain during most of the summer and early fall.

Concentrations at Well M have historically fluctuated with variable precipitation.

Beyond the limits of the cofferdam, tritium concentrations in groundwater samples also continue to be generally stable or decreasing. Well W has shown a slight increase in concentration. Wells S and AO have not been operating recently due to low yield and

Mr. Kent Tosch 2 11/11105 the diesel fuel investigation, respectively. This has temporarily reduced the degree of control exerted by the Groundwater Extraction System (GES) on this portion of the plume. The mobile unit has been used in the interim period to maintain control in this area. The mobile unit remains on standby in the event that concentrations continue to rise in Well W. The mobile unit has already been effective in reducing the increased concentrations observed in samples collected from Well AP. Well AO has been placed back into service and the adjacent diesel fuel well is being closely monitored to see if diesel fuel is being drawn into that well.

To date the groundwater analytical data continues to indicate that the GES is effective at recovering tritium and thereby reducing the overall amount of tritium in groundwater.

The pilot system removed approximately 0.9 curies during the 10 months that it was operational and the GES has removed approximately 0.6 curies during Its period of operation.

Groundwater Extraction Inaccordance with the RAWP, groundwater extraction activities continue using the GES that was activated on February 16, 2005.

Full-Scale System The GES system consists of the extraction of groundwater from Wells S, AB, AD, AJ, AN, AS and AT. Well AO continues to be out of service to prevent interference with diesel fuel oil recovery operations and Well S has been operating intermittently as a result of the well's low yield. Additionally, Wells AO, AN, AS and AT required wiring modifications and were temporarily out of service. All eight extraction well pumps are currently in service.

As of September 22, 2005, the GES system has recovered greater than 2.7 million gallons of groundwater. Total well field operations have resulted in the recovery of 1.48 curies of tritium. The results of the groundwater remediation activities conducted using the well field are summarized on Figure 2. The recent average system effluent concentrations are presently around 47,000 pCi/L of tritium.

The various groundwater recovery activities conducted to date have been, and continue to be successful in recovering tritium from groundwater at and down gradient of the Salem Unit-1 seismic gap.

Operation of the Seismic Gap Drain To date, periodic operation of the seismic gap drain in Unit 1 has resulted in the recovery of approximately 25,400 gallons of tritiated water. Figure 3, presents a summary of the activity of the Unit 1 Seismic Gap drain. As of September 28, 2005 a total of approximately 3.98 curies of tritium has been recovered from the operation of

Mr. Kent Tosch 3 11/11/05 the Unit 1 seismic gap drain. Unit 2 gap water continues to indicate no plant related gamma activity.

Upcoming Activities Activities projected for the Fourth Quarter of 2005 (through December) include the following:

• Completion of present corrective maintenance activities on the groundwater extraction system (all eight extraction pumps are operating at the time of this report).

• 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;

• Continued operation and evaluation of data obtained through the full-scale groundwater extraction system; and,

• Place well AO pump back into service on a trial basis, and closely monitor diesel fuel well adjacent to well AO to observe whether or not diesel fuel is being drawn to that well. If no diesel fuel is observed, well AO will remain in service.
