The purpose of the assessment was to identify the potential presence and extent of radiological materials in groundwater within the assessment area of the line with respect to the integrity of the line.The initial assessment activities were conducted at the Site from January 21, 2009 through March 4, 2009. This Assessment Report, issued on April 1, 2009, provides a presentation of the activities completed and the findings of the assessment.

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 site.The Site location is depicted on Figure 1.The Cooling Tower Blowdown Line, 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. The line assessment area is located between Air Release System Manhole#1 (ARS#l) which is located adjacent to the composite sampler shed (approximately 0.5 miles from the cooling tower) to ARS#2, located approximately 1,110 feet south of ARS#1. The assessment area is also depicted on Figure 1.1-1 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant April 2009 1.2.2 Project Background On December 15, 2008, Progress Energy personnel discovered the presence of water in 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 was continuing to enter the bottom of the manhole through a 2-inch pipe designed to drain the manhole. A water sample was collected and analyzed for tritium. Tritium was detected at an approximate concentration of 800 pCi/l. Based on these observations, Progress Energy determined that additional evaluation was warranted.

1.3 Scope and Objectives The overall objectives of the Cooling Tower Blowdown Line Assessment are as follows: " Characterize the hydrogeology and geology in the area* Provide groundwater sampling and elevation measuring points* Evaluate groundwater flow and groundwater quality* Assess potential sources of tritium concentration in water.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.1.4 Report Organization The organization and content of the remainder of this report are described below.Section 2.0 -Investigation Activities and Findings A summary of the activities completed during planning and implementation of the assessment is provided.

The methods, locations, and results of the sampling and analysis program are presented in detail for soil and groundwater.

1-2 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant April 2009 Section 3.0 -Physical Characteristics of the Study Area A description of the study area including surface features, geology and soils, surface water hydrology, and groundwater hydrology is provided in Section 3.Section 4.0 -Summary and Conclusions A summary of the relevant environmental conditions to satisfy the objectives of the investigation is provided in Section 4.2 ASSESSMENT ACTIVITIES AND FINDINGS The planning of the assessment activities included a number of conference calls and meetings with appropriate plant personnel.

A scope of work to complete the assessment objectives was prepared by SSi and submitted to Progress Energy on January 6, 2009. The initial scope of work called for the installation of up to 20 shallow (approximately 25 feet below ground surface or bgs) soil borings/monitoring wells to complete the study objectives.

The assessment field activities were completed in two phases. The first phase was completed from January 21 to February 6, 2009, and included the following activities: " Installation of six (6) groundwater monitoring wells BDL-MW1 through BDL-MW6 at points along the blowdown line and near ARS#2," Collection of preliminary groundwater samples from BDL-MW1, BDL-MW2, and BDL-MW-3 on January 23, 2009, and* Water level measurements and preliminary groundwater samples from BDL-MW5 and BDL-MW6 on February 6, 2009.Based on these initial activities and findings, the original scope of work was revised to reduce the number of wells due to the general absence of shallow groundwater.

The second phase of the assessment was completed from February 17 to March 4, 2009, and included: 2-3 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant April 2009" Installation of three (3) groundwater monitoring wells BDL-MW7 through BDL-MW9 at ARS#2 and downgradient of ARS#2 toward Harris Lake,* Measuring water level elevations on March 3, 2009, and* Collecting a complete round of water samples from the monitoring wells and ARS#2 on March 4, 2009.These activities are described in detail below. The locations of the groundwater monitoring wells installed in the area are depicted on Figure 2.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 (picocuries per liter).2.1 Assessment Activities To accomplish the objectives of ote assessment, several investigatin actites complted including:

soil borings/monitoning well installation, groundwater elation me andgrounhwater, sampling.The assessment methods and, results, are, discussed in the following subsections.

Objective 1.3a Installation of .1 Soil] Boings/Groundwater' Monitoring Well Installation:

additional monitoring wells he primary objectives of the soil boring/monitoring well installation were to evaluate subsurface conditions and establish a network of monitoring wells in the Cooling Tower Blowdown Line assessment area to evaluate geology, hydrogeology and groundwater quality. To accomplish this objective, soil borings were advanced and monitoring wells were installed at the locations illustrated on Figure 2. Boreholes were logged from split spoon samples and cuttings.

The screened interval for each monitoring well was selected to intersect the depth intervals where groundwater was observed.

Where no groundwater was observed the bottom of the screened interval was 2-4 Cooling Tower Blowdown Line Assessment Report Shearon Harris Nuclear Power Plant April 2009 placed at the maximum penetration depth of the drilling technique and below observed water levels in the adjacent manholes.Hollow-stem auger (HSA) drilling methods were employed to complete the installation of groundwater monitoring wells BDL-MW1 through BDL-MW6. HSA and air rotary drilling methods were employed to complete the installation of groundwater monitoring wells BDL-MW7 through BDL-MW9. The drilling activities are described in the following sections.During the investigation, a total of nine (9) shallow 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.

Where no groundwater was observed, the bottom of the well was set at the maximum drilling depth using the HSA techniques (BDL-MW 4 through BDL-MW6, only) and below the water level in ARS#2.* The wells were generally installed using 4'/4-inch inside diameter (ID)hollow stem augers and/or 4-inch air hammer.* At least ten feet of 2-inch-ID, Schedule 40 PVC, machine cut, well screen with 0.020-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.* 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.* All wells were completed as stick-up wells, with lockable expansion plugs.2-5 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant April 2009" A concrete pad will be installed around the wells that are determined by Progress Energy and SSi to be completed as permanent wells.* 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 Logs included in Appendix A. NCDENR Well Construction Records are included in Appendix B.2.1.2 Groundwater Elevation Measurements Groundwater elevation measurements were collected from the monitoring wells and used to provide data to map the potentiometric surface of the aquifer and interpret the horizontal groundwater flow in the aquifer. One complete round of depth-to-water measurements was collected from the nine monitoring wells on March 3, 2009.Measurements were collected using a Solinst Level Indicator Probe capable of measuring depth to water within 0.01-foot accuracy.

Results of these measurements are summarized in Table 2, presented on Figure 3, and discussed in Section 3 of this report.2.1.3 Groundwater Sampling One round of groundwater samples was collected from the monitoring wells. All monitoring wells were sampled except BDL-MW4, which was dry. In addition, a water sample was collected directly from the drainpipe in manhole ARS#2. 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.

In addition, select water samples were analyzed for total zinc.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 sampling was completed using a peristaltic pump, dedicated 2-6 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant tý .April 2009 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 (pH, temperature, dissolved oxygen, conductivity, and oxidation/reduction potential) were collected during the purging activities and recorded in the field logbook (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 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.ARS#2 was sampled in general accordance with the methodology specified above.2-7 Cooling Tower Blowdown Line Assessment Report Shearon Harris Nuclear Power Plant April 2009 2.2 Assessment Findings -Water Results Groundwater samples were collected from the monitoring wells on March 4, 2009. All water samples from the wells (8 samples) and manhole (I sample) were analyzed for tritium at the on-site radiological analytical laboratory.

Samples from BDL-MW1, BDL-MW5, BDL-MW8, and ARS#2 were also analyzed for zinc, since zinc is added to the cooling water and can be used as a marker analyte. Analytical results are summarized in Table 3. Figure 4 depicts the analytical results for tritium in the water samples. The results are summarized below.* Tritium was detected in five (5) of the eight (8) monitoring wells sampled and in the ARS#2 sample. The detection limit for the analyses was approximately 233 pCi/L.* Tritium in the nine (9) samples ranged from less than the detection limit (three wells) to 2,120 pCi/L at manhole ARS#2." The highest concentration of tritium detected in the samples was detected in the immediate area of ARS#2 (ARS#2, BDL-MW5, and BDL-MW6).

The second highest concentration of tritium was detected at BDL-MW3, near the wetland in the area of groundwater discharge.

These three wells are located in close proximity to the backfilled trench of the blowdown line which is likely acting as a preferential pathway of water transport.

• The horizontal migration of tritium in groundwater from the blowdown line appears to be limited as no tritium was detected in samples from BDL-MW8 and BDL-MW9.* The vertical migration of tritium in groundwater from the blowdown line appears to be limited as no tritium was detected in the sample from BDL-MW7.2-8 Cooling Tower Blowdown Line Assessment Report Shearon Harris Nuclear Power Plant April 2009 The highest concentration of zinc was detected in the sample from ARS#2 at a concentration of 187 ug/l, lower concentrations of zinc were detected in samples from BDL-MW8 (96 ug/h), BDL-MW5 (18 ug/1) and BDL-MW1 (8 ug/1).Based on the occurrence and distribution of tritium in the water samples, it appears that the source of tritium is a leak(s) along the Cooling Tower Blowdown Line. Analysis of the hydrogeology and groundwater conditions within the area is presented and discussed in Section 3, and further discussion regarding the possible sources of tritium is presented in Section 4. Conclusions and potential additional activities that may be performed to further evaluate the blowdown line are also presented in Section 4.2.3 Surveying and Mapping A site survey was performed and certified by a North Carolina Registered Land Surveyor (Smith and Smith). Initial surveying activities were performed on January 22, 2009 during which time the centerline of the Cooling Tower Blowdown Line was located and demarcated.

On February 20, 2009 all monitoring wells, manhole ARS#1, and manhole ARS#2 were surveyed.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 basemap for this Assessment Report.2-9 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant tý April 2009 3 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.

3.1 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. The area of the Cooling Tower Blowdown Line, which is the focus of this assessment, includes approximately 15 acres.As discussed in Section 1, 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. Specifically, the blowdown line assessment area is located between ARS#1, located adjacent to the composite sampler shed (approximately 0.5 miles from the cooling tower), to ARS#2 which is located approximately 1,110 feet south of ARS# 1. 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 2.3.2 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 3-1 Cooling Tower Blowdown Line Assessment Report 8 8 .Shearon Harris Nuclear Power Plant April 2009 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. Soil borings encountered a thin layer of unconsolidated material (overburden), underlain by a reddish-brown weathered siltstone bedrock (regolith) underlain by reddish-brown siltstone.

A site-specific interpretation of the geology in the area has been developed by using boring logs from the assessment activities and is presented as a cross-section on Figure 5.3.3 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#l. Historic groundwater elevation at this location was approximately 235' MSL.Groundwater monitoring activities were performed during this assessment to determine if the water entering ARS#2 is groundwater from the surrounding area, (i.e. is local groundwater discharging to ARS#2). Based on the depth to water in ARS#2, approximately 7 feet below ground surface (bgs), it was assumed that only shallow monitoring wells would be required to complete this study objective.

Therefore, eight (8) shallow (less than 30 feet bgs) and one (1) deep (approximately 60 feet bgs) wells were installed during the assessment.

One complete round of water level measurements was collected.

Those water level measurements and resulting elevations are shown on Figure 3. Groundwater elevations are also shown on the geologic cross-section included as Figure 5. As indicated, the groundwater elevations are highly variable 3-2 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant April 2009 particularly in the area of ARS#2. General observations regarding the assessment area groundwater are as follows: " In the area of ARS#l, as characterized by BDL-MW1 through BDL-MW3, groundwater elevations indicate flow to the south toward the topographic low/wetland." In the area of ARS#2, water was detected in BDL-MW5 and BDL-MW6 several days after the wells were installed, however BDL-MW4 remains dry. This indicates that the water observed in BDL-MW5 and BDL-MW6 is not from a local/regional groundwater source.* The water elevation in ARS#2 is higher than that in BDL-MW5 and BDL-MW6 indicating that flow is from the immediate vicinity of ARS#2 to these monitoring wells and not from a local/regional groundwater source.* In the area of ARS#2, groundwater was detected in BDL-MW7 at a significantly lower elevation that the water levels detected in BDL-MW5 and BDL-MW6, indicating that the regional groundwater elevation may be significantly lower than the water level observed in BDL-MW5 and BDL-MW6.* The groundwater elevation at BDL-MW8 was measured to be at or above the ground surface indicating local artesian conditions at this location.* The groundwater elevation at BDL-MW9, which is located approximately 40 feet from the edge of Harris Lake, was measure at an elevation

(-210 feet MSL)approximately 10 feet below the surface water level indicating that surface water from Harris Lake may be discharging to groundwater in this area.3-3 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant April 2009 4

SUMMARY

AND CONCLUSIONS Silar Services Incorporated (SSi) has prepared this Cooling Tower Blowdown Line Assessment Report to document the results of investigation activities performed along a section of the line at the Shearon Harris Nuclear Power Plant, located in New Hill, North Carolina.

The purpose of the assessment was to identify the potential presence and extent of radiological materials in groundwater within the area of the line with respect to the integrity of the line.The Cooling Tower Blowdown Line runs underground for approximately 2 miles from the cooling tower south to the edge of Harris Lake. The line assessment area is located between Air Release System Manhole #1 (ARS#1), which is located adjacent to the composite sampler shed (approximately 0.5 miles from the cooling tower), to ARS#2, located approximately 1,110 feet south of ARS#1. The overall objectives of the Cooling Tower Blowdown Line assessment are as follows:* Characterize the hydrogeology and geology in the area* Provide groundwater sampling and elevation measuring points* Evaluate groundwater flow and groundwater quality" Assess potential sources of tritium concentration in water.<The assessment field activities were completed intwo phases. The first phase included the foll6owing activities:

Samples from BDL-MW1, BDL-MW5, BDL-MW8, and ARS#2 were also analyzed for zinc, since zinc is added to the cooling water and can be used as a marker analyte. Tritium was detected in five (5) of the eight (8) monitoring wells sampled and in the ARS#2 sample at concentrations up to 2,120 pCi/L. (detected at ARS#2).The highest .concentration of tritium detected in the samples was detected in the immediate area of ARS#2 (ARS#2, BDL-MW5, and BDL-MW6).

The next highest concentration of tritium was detected at BDL-MW3, near the wetland in the area of groundwater discharge.

The highest concentration of zinc was detected in the sample Objective 1.1c ..' RS#2 at a concentration of 187 ug/l.

This is based on several observations.

The highest observed tritium concentration was in the sample from the ARS#2 and its immediate vicinity.

The water elevation in ARS#2 is higher than water elevations measured in BDL-MW5 and BDL-MW6, indicating that flow is from the immediate vicinity of ARS#2 to these monitoring wells. In the area of ARS#2, groundwater was detected in BDL-MW7 at a significantly lower elevation than the water levels detected in BDL-MW5 and BDL-MW6, indicating that the regional groundwater elevation may be significantly lower than the water level observed in BDL-MW5 and BDL-MW6. Water was observed to be entering ARS#2 through a pipe that was designed to drain water from the manhole to the surrounding backfill.

It is possible that the backfill surrounding the blowdown line has created a preferential pathway for the flow of water. Water leaking from the pipeline in the vicinity of ARS#2, or at some point in the pipeline at a higher elevation, may be traveling along this preferential "horizontal" pathway as it also infiltrates the surrounding natural material toward the regional water table elevation.

This would create an apparent groundwater mound adjacent to the line in areas where it is above the regional water table.4-3 Cooling Tower Blowdown Line Assessment Report Shearon Harris Nuclear Power Plant April 2009 Further investigation is recommended including, but not limited to, the following:

• Evaluation of all manholes in the blowdown line* Installation of sampling points within the blowdown line backfill* Evaluation of the line integrity utilizing video surveillance and or pressure/exfiltration testing.4-4 Cooling Tower Blowdown Line Assessment Report s s .Shearon Harris Nuclear Power Plant Cýý April 2009 FIGURES N Shearon Hanls Nuclear Power Plant eiw Now HIn.
