INTRODUCTION 1.1 Purpose of Report Silar Services Incorporated (SSi) has prepared this Cooling Tower Blowdown Line (CTBL) Supplemental Groundwater Assessment Report to document the results of investigation activities performed along the CTBL at the Shearon Harris Nuclear Power Plant (SHNPP), located in New Hill, North Carolina. The purpose of this assessment is to further investigate the potential presence and extent of radiological materials in groundwater within the vicinity of the line with respect to the integrity of the line.

1.2 Project Background This section includes information on the location, description and history of the Site.

1.2.1 Project Location The Shearon Harris Nuclear Power Plant is located approximately 1.6-miles east of the Town of New Hill, North Carolina, and is situated on approximately 10,700 acres. The Site location is depicted on Figure 1.

The CTBL, which is buried several feet below the ground surface, runs for approximately 2 miles from the cooling tower south to the edge of Harris Lake and thence, approximately 2 additional miles to its discharge point beneath the lake. The CTBL is also depicted on Figure 1.

1.2.2 Project Background On December 15, 2008, Progress Energy personnel discovered the presence of water in Air Release System Manhole ARS#2. The manhole was investigated by purging the water from the manhole and evaluating conditions. It was observed that subsequent to purging the manhole dry, water continued to enter the bottom of the manhole through a 2-inch pipe designed to drain the manhole. A water sample was collected and analyzed 1-1

Cooling Tower Blowdown Line Supplemental Groundwater Assessment Report Shearon Harris Nuclear Power Plant December 2009 for tritium. Tritium was detected at an approximate concentration of 800 picocuries per liter (pCi/L). Based on these observations, Progress Energy determined that additional evaluation was warranted.

Initial assessment activities were conducted at the Site from January 21, 2009 through March 4, 2009. An Assessment Report, issued on April 1, 2009, provided an analysis of groundwater conditions as determined through the installation of nine (9) monitoring wells installed within a limited study area along the length of the pipeline between ARS#1 and ARS#2.

This assessment identified tritium in groundwater in the immediate area of ARS#2 at concentrations up to 1,450 pCi/L.

Tritium was also identified at 1,060 pCi/L in a groundwater well located along the pipeline approximately 655 feet north of ARS#2 (approximately 460 feet south of ARS#1).

Tritium was also detected in groundwater at 372 pCi/L near ARS#1 and approximately 335 feet south of ARS#1 at 373pCi/L. The report also presented a fate and transport evaluation for tritium identified at ARS#2, estimating that groundwater flow was generally trending east-northeast from the vicinity of ARS#2 at a rate of 1.14 foot/day or 208 feet/year. Further evaluation of the pipeline and the surrounding groundwater was recommended as a result of these findings.

A pipeline inspection was performed in April 2009. Approximately 5,600 feet of the targeted 8,800 feet of pipeline were able to be accessed and manually inspected. The inspection revealed that the pipeline exhibits deformation, cracking and buckling throughout the entire length.

One repair of note was successfully conducted at a leaking joint in the pipeline located approximately 200 feet south of ARS#2.

Additional leaks that were not amenable to repair were also identified.

SITNPP is currently planning pipeline replacement alternatives 1-2

Supplemental Groundwater Assessment Report Shearon Harris Nuclear Power Plant December 2009 1.3 Scope and Objectives As a result of an evaluation of the abovementioned studies, the installation of seven (7) additional monitoring wells along the CTBL was approved. The objectives of the installation of these wells include:

Evaluate groundwater quality near locations along the pipeline that could not be manually inspected.

Evaluate groundwater quality at locations identified during the inspection as likely points of leakage from the pipeline.

Further characterize the hydrogeology and geology along the length of the pipeline.

Provide groundwater monitoring and elevation measuring points along the length of the pipeline.

The scope of the assessment included the collection of data as close as reasonably possible to the Cooling Tower Blowdown Line while not compromising the integrity of the line.

PHYSICAL CHARACTERISTICS OF THE STUDY AREA This section presents the physical characteristics of the Site including surface features, geology, surface water hydrology, and groundwater hydrology.

2.1 Surface Features The SHNPP is located approximately 1.6 miles east of the Town of New Hill, North Carolina. Access to the SHNPP is from Shearon Harris Road. The owner controlled area encompasses approximately 10,700 acres.

As previously discussed, the Cooling Tower Blowdown Line runs underground for approximately 2 miles from the Cooling Tower south to the edge of Harris Lake. The assessment area is on a peninsula which is surrounded by Harris Lake to the south, east, and west and bounded to the north by SHNPP. The most significant surface feature in the assessment area is the topographic low area/wetlands, situated along the blowdown line approximately midway between ARS#1 and ARS#2. There is an approximately 30-foot elevation change between ARS#1 and the topographic low to the south. In addition, a portion of Harris Lake is located east of manhole ARS#2.

The Site location is shown on Figure 1, and the Site Layout is depicted on Figure 2.

2.2 Geology Regional and site-specific geology have been extensively evaluated by others during the safety analyses for Unit 1 and more recently for proposed Units 2 and 3. These reports indicate that the plant is underlain by the Upper Triassic Age Newark Supergroup. The group is characterized by siltstone and sandstone with subordinate amounts of claystone and conglomerated and igneous diabase intrusions. Additional information on regional and local geology can be found in the Final Safety Analysis Report (FSAR).

Site-specific geology observed in the area of the blowdown line is consistent with the regional geology.

A site-specific interpretation of the geology in the area has been developed by using boring logs from the previous and current assessment activities and is presented in cross-sections on Figures 3 and 4.

2.3 Groundwater Hydrology Regional and site-specific groundwater hydrology have been extensively evaluated by others during the safety analyses for Unit 1 and more recently for proposed Units 2 and

3.

These reports indicate that the groundwater hydrology within the plant area is relatively complex as a result of the influence of the main and auxiliary reservoirs and the nature of the parent rock. The previous groundwater studies have focused on the plant area, located to the north of this assessment area. The nearest previously existing monitoring well is MWA-12, which is located approximately 1,000 feet northeast of ARS#1.

Historic groundwater elevation at this location was approximately 235 ft.

MSL.

Two rounds of water level measurements were collected from the newly installed monitoring wells in October and November 2009 as discussed later in Section 3 of this report.

The water level measurements collected in October 2009 and resulting elevations from both the newly installed monitoring wells and the existing monitoring wells are shown on the cross-sections presented as Figures 3 and 4.

General observations regarding the assessment area groundwater are as follows:

The water table aquifer is variable and is influenced by several factors including the the reservoirs (Harris Lake), topography and the slope of the bedrock.

Shallow groundwater is influenced by the bedrock surface as shown in the cross-sections. Groundwater generally flows from to the south and east along the pipeline from the plant and is influenced by the finger of Harris Lake near monitoring well BDL-MW-9 and the Lake at BDL-MW-16 and Drop Structure B.

ASSESSMENT ACTIVITIESAND FINDINGS.3 The planning of the assessment activities included conference calls and meetings with Progress Energy representatives and appropriate plant personnel. A scope of work to complete the assessment objectives was prepared by SSi and submitted to Progress Energy on May 4, 2009. Based on a review of the previous studies and planning meetings with Progress Energy personnel, the scope of work was finalized to include the installation of seven (7) permanent monitoring wells along the pipeline and to add the installation of three monitoring wells located within the vicinity of the plant to provide additional groundwater monitoring points not specifically related to the CTBL.

It should be noted that two of the three wells installed at the plant area were installed in the general vicinity of the pipeline, and these results have been included in the pipeline assessment for that area.

Monitoring well installation was conducted from September 21, 2009 through October 2, 2009. Monitoring wells BDL-MWIO through BDL-MW16 were completed with above-ground protective casings and protective bollards were installed surrounding the wells. GW-74 through GW-76 were completed as flush mounts. These activities are described in detail below. The locations of the installed groundwater monitoring wells are shown on Figure 2.

g The activities and findings are summarized in the following subsections. The analytical results are presented and, where concentrations of radiological materials were observed, the results are also presented on figures. Throughout this section, groundwater data are discussed with respect to the USEPA drinking water standard of 20,000 pCi/L.

3.1 Assessment Activities To accomplish the objectives of the assessment, several investigation activities were completed including: monitoring well installation, groundwater elevation measurements and groundwater sampling. The assessment methods and results are discussed in the following subsections.

3. 1.1 Groundwater Monitoring Well Installation The primary objective of the monitoring well installation was to further evaluate subsurface conditions and establish a network of monitoring wells along the CTBL to evaluate geology, hydrogeology and groundwater quality. To accomplish this objective monitoring wells were installed using air rotary drilling methods at the locations 3-2

Cooling Tower Blowdown Line Supplemental Groundwater Assessment Report Shearon Harris Nuclear Power Plant December 2009 illustrated on Figure 2.

Cuttings were observed and boreholes were logged from cuttings. The screened interval for each monitoring well was selected to intersect the depth intervals where groundwater was observed. In cases where no groundwater was observed during drilling, the drilling was discontinued for a period and the open borehole was monitored for water infiltration. If no water infiltration was observed, the borehole was advanced further.

During the investigation, ten (10) groundwater monitoring wells were installed as shown on Figure 2.

The general monitoring well installation procedures are summarized below.

The depth for each of the wells was selected based on presence and depth of groundwater at each well location.

The boreholes were advanced using a 6-inch rotary-air hammer.

In the vicinity of the plant, an air-knife was used to open the borehole prior to drilling to avoid utilities.

With the exception of GW-76, based on the observations during drilling, fifteen (15) or twenty (20) feet of 2-inch-ID, Schedule 40 PVC, machine cut, well screen with 0.010-inch slot size was set at the bottom of each well. A sufficient length of 2-inch ID, Schedule 40 PVC riser pipe was coupled to the screen to allow the PVC riser pipe to extend a minimum of two feet above the ground surface. Well screens were fitted with a nominal 2-inch solid (unslotted) bottom sediment trap. GW-76 was installed with five feet of 0.010-inch screen due to the immediate presence of water.

The annular space around the well screens was backfilled with clean uniform sand (filter pack sieve #2). The filter pack was placed from the bottom of the well to a minimum of 2 feet above the top of the well screen.

A minimum 2-foot-thick bentonite seal was placed above the sand and allowed to hydrate.

" Monitoring wells BDL-MW-10 through BDL-MW-16 were completed as stick-up wells, with lockable expansion plugs.

3-3

Cooling Tower Blowdown Line s s.

Supplemental Groundwater Assessment Report Shearon Harris Nuclear Power Plant December 2009 Monitoring wells GW-74, GW-75, and GW-76 were completed as flush mounts, with lockable expansion plugs.

A concrete pad was installed around each well, and protective bollards were installed around the well stick-ups.

Boring logs were prepared for each monitoring well.

A summary of the monitoring well construction details is provided in Table 1 and depicted in the Boring/Well Construction Logs included in Appendix A. NCDENR Well Construction Records are included in Appendix B.

3.1.2 Existing Monitoring Well Completion and Abandonment During the field activities associated with the assessment, SSi reconstructed existing temporary monitoring wells to be permanent monitoring wells. Monitoring wells BDL-MW-1 through BDL-MW-3 and BDL-MW-5 through BDL-MW-9 were completed as stick-up wells by installing a locking protective outer casing and a concrete pad at ground surface. Protective bollards were also installed around the well stick-up.

Monitoring well BDL-MW-4 was abandoned.

3.1.2 Monitoring Well Surveying and Mapping The monitoring well casings and ground elevations were surveyed and certified by a North Carolina Registered Land Surveyor (Smith and Smith).

The survey was completed on October 20. Monitoring wells MW-i through MW-9 were resurveyed because the top of the wells were modified to allow for the installation of the protective outer casing.

A survey map was produced that includes scale, benchmarks, North arrow, and the locations of monitoring wells. The survey map provided the information required to produce a site base map for this Assessment Report.

Cooling Tower Blowdown Line s s.

Supplemental Groundwater Assessment Report Shearon Harris Nuclear Power Plant December 2009 3.1.3 Groundwater Elevation Measurements Groundwater elevation measurements were collected from the monitoring wells and used to provide data to interpret the potentiometric surface of the aquifer. Depth-to-water measurements were obtained from the ten monitoring wells prior to sampling on October 13 and November 9, 2009. Measurements were collected using a Solinst Level Indicator Probe capable of measuring depth to water within 0.01-foot accuracy.

3.1.3 Groundwater Sampling Groundwater samples were obtained from the monitoring wells in October and November 2009. In addition, during the November sampling effort, a surface water sample was collected directly from Harris Lake at the shoreline near Drop Structure B (DS-B). Water samples were analyzed for tritium at Progress Energy's Harris Energy and Environmental Center Radiochemistry Laboratory to the same lower limit of detection as the NC Division of Radiation Protection (NCDRP) laboratory.

Prior to sampling, each monitoring well was purged in accordance with low-flow groundwater sampling procedures to assure collection of a representative groundwater sample. Groundwater purging and sampling was completed using a peristaltic pump (except as noted below), dedicated pump (flex) tubing, and dedicated down-hole polyethylene tubing at each monitoring well to eliminate the potential for cross-contamination between sampling points.

Water quality measurements (temperature, conductivity, pH, and dissolved oxygen) were collected during the purging activities and recorded in the field logbook. Sample log forms are included as Appendix C. The procedure for monitoring well purging and sampling is generally as follows:

The security cap was removed, and the depth to water in the well was determined with a water level meter. The depth to water was recorded in the field logbook.

The dedicated down-hole tubing was lowered into the monitoring well, cut to the desired length, attached to the pre-cut flex tubing on the peristaltic pump, a 3-5

Cooling Tower Blowdown Line s s.

Supplemental Groundwater Assessment Report Shearon Harris Nuclear Power Plant December 2009 new section of poly tubing was inserted on the effluent side of the pump. The sample line was connected from the pump to the in-line water quality instrument (YSI MP556 with flow through cell), the effluent line from the flow-through cell was inserted into a purge water container to capture purge water, the peristaltic pump was started, and purging of groundwater at the well was commenced.

An optimum low-flow pumping rate was established at each well to minimize drawdown.

The groundwater quality parameters and depth to water were monitored and recorded at prescribed time intervals to determine when the water quality parameters had stabilized to within 10%.

Following the stabilization of the groundwater quality parameters, groundwater samples were collected from the wells and delivered to the radiological analytical laboratory.

Purge water was collected and transported to the designated disposal point.

It should be noted that for both the October and November sample rounds wells BDL-MW-14 and GW-74 were sampled using a dedicated disposable bailer. During the October sampling event, low-flow sampling was attempted at both wells using a low-flow submersible pump; however, the wells produced a significant amount of silt and the pump failed.

3.2 Groundwater Analytical Results 3.2.1 October 2009 SSi collected groundwater samples from the newly installed monitoring wells (BDL-MW-10 though BDL-MW-16 and GW-74 through GW-76) on October 13-15, 2009.

All water samples from the wells (10 samples) were analyzed for tritium at the on-site radiological analytical laboratory. SHNPP personnel collected groundwater from the existing monitoring wells (BDL-MW-1 through BDL-MW-3 and BDL-MW-5 through 3-6

Cooling Tower Blowdown Line Supplemental Groundwater Assessment Report Shearon Harris Nuclear Power Plant December 2009 BDL-MW-9) on October 15, 2009.

Analytical results are summarized in Table 2.

Figure 5 depicts the analytical results for tritium in the water samples.

Tritium was detected in groundwater from one (1) of the ten (10) newly installed monitoring wells. The lower limit of detection (LLD) for the analyses ranged from 235 pCi/L to 241 pCi/L. Tritium was detected in the groundwater sample from BDL-MW-16 at 5,870 pCi/L. Tritium was also detected in five (5) of the existing CTBL monitoring wells (BDL-MW-2, BDL-MW-3, BDL-MW-5, BDL-MW-6 and BDL-MW-

7) at concentrations ranging from 326 pCi/L in BDL-MW-7 to 1,070 pCi/L in BDL-MW-5.

3.2.2 November 2009 SSi collected groundwater samples from the newly installed monitoring wells and a surface water sample from Harris Lake on November 9 and 10, 2009. All eleven (11) samples were analyzed for tritium at the on-site radiological analytical laboratory.

SHNPP personnel collected groundwater from the existing monitoring wells (BDL-MW-1 through BDL-MW-3 and BDL-MW-5 through BDL-MW-9) on November 23, 2009. Analytical results are summarized in Table 2. Figure 6 depicts the analytical results for tritium in the water samples.

Tritium was detected in groundwater from one (1) of the ten (10) newly installed monitoring wells sampled. The LLD ranged from 235 pCi/L to 241 pCi/L. Tritium was detected in the groundwater sample from BDL-MW-16 at 3,410 pCi/L. Tritium was detected in surface water sample from Harris Lake at 3,550 pCi/L. Tritium was also detected in five (5) of the existing CTBL monitoring wells (BDL-MW-2, BDL-MW-3, BDL-MW-5, BDL-MW-6 and BDL-MW-7) at concentrations ranging from 361 pCi/L in BDL-MW-6 to 1,180 pCi/L in BDL-MW-5.

Conclusions and recommendations are presented in Section 4.

were installed in the ~general vicinity of the pipeline.

4.1 Summary of Groundwater Conditions Two rounds of groundwater samples were collected from the newly installed monitoring wells (10 samples) and the existing monitoring wells (8 samples) and one sample was obtained from Harris Lake during the second sampling round.

All groundwater samples were submitted to the on-site radiological analytical laboratory for tritium analysis. Tritium results for the existing CTBL monitoring wells were consistent with those from the initial investigation in early 2009 and the ongoing monthly sampling effort. These results indicate the presence of a current and/or historic leak in the pipeline in the vicinity of ARS#2. Investigations. have demonstrated that this area is a low point in the pipeline where leaked water from the pipeline might accumulate. With respect to the newly installed monitoring wells, tritium was detected in the groundwater samples from BDL-MW-16 at 5,870 pCi/L (October 2009) and 3,410 pCi/L (November 2009). None of the groundwater samples from the other newly installed monitoring wells exhibited tritium above the LLD. Because MW-16 was installed less than 800 feet from Harris Lake, a sample was obtained from the lake 4-1

Cooling Tower Blowdown Line 8 8.

Supplemental Groundwater Assessment Report Shearon Harris Nuclear Power Plant December 2009 during the second sampling round conducted in November.

This sample exhibited tritium at 3,550 pCi/L.

Defects in the CTBL were identified in the vicinity of Drop Structure B during the April 2009 pipeline inspection and leakage from the pipeline may be a source of tritium impacts in this area; however, the similarity in results from this well and the lake imply a possible connection between the lake and shallow groundwater in the vicinity of Drop Structure B.

As Harris Lake is manmade, it is possible that the lake discharges to groundwater in areas. Harris Lake elevations as recorded at the plant intake structure were provided by plant personnel for the time periods of both sampling rounds. These data indicate that the elevation of Harris Lake where measured was lower than the water table at MW-16 for both sampling rounds.

4.2 Conclusions Based on the occurrence and distribution of tritium in the data presented above, it is concluded that groundwater in the vicinity of MW-16 has been impacted by tritium.

This may be a result of leakage from the CTBL defects previously identified or discharge from Harris Lake. Groundwater impacts previously identified in the local area between ARS#1 and ARS#2 identified in the April 2009 Groundwater Assessment Report persist. No other areas of tritium-impacted groundwater have been identified as a result of this scope of work.

4.3 Recommendations SSi recommends that the newly installed monitoring wells be added to the monthly sampling protocol as part of the site Groundwater Monitoring Program so that sufficient data can be accumulated to evaluate trends and seasonal effects.

In addition, an evaluation of the hydrologic connection between Harris Lake and shallow groundwater should be performed to determine if impacted lake water is migrating to and impacting groundwater in the vicinity of MW-16 or elsewhere.
