SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 9801-0000 RELEASE RECORD SURVEY UNIT DESCRIPTION Based on the Connecticut State Plane System, North American Datum (NAD) 1927, this subsurface Survey Unit (980 1-0000) is located approximately one thousand two hundred and seventy-one (1,271) feet (ft) to the southeast of the site benchmark (Northing: 237370.20, Easting: 667394.51). The survey area has a total surface area of approximately fifteen thousand seven hundred and eighty-eight (15,788) square meters (in 2 ).

LTP Section 2.3.3.1.5 defines a subsurface Class A area as a subsurface soil area that has had known contaminating events and has a high potential to be at or exceed the DCGL. Consequently, following evaluation of historical events and an assessment of radiological surveys performed in support of characterization and remediation, subsurface Survey Area 9801, which contains subsurface Survey Unit 9801-0000, received a final classification as subsurface Class A.

9802 The subsurface Survey Unit 9801-0000 corresponds to the surface Survey Units 9312-0001 through 9312-0010. Survey Units 9312-0009 & 9312-0010 include the rock wall on the east side of the former RCA. All of the aforementioned surface survey units are classified as Class 1.

Revision 03 3

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 9801 -0000 RELEASE RECORD The reference coordinates associated with this survey unit are E008 through E016 by S065 through S072 (refer to "HNP License Termination Plan" (LTP) Section 5.4.4). The reference coordinates provide the maximum dimensions of a rectangle containing this survey unit. Some areas contained in this rectangle may not be part of this survey unit. The boundary of the survey unit was defined using a Global Positioning System (GPS) based on the Connecticut State Plane System North American Datum (NAD) 1927.

2. CLASSIFICATION BASIS The survey unit was classified in accordance with Procedure RPM 5.1-10, "Survey Unit Classifiation."

The "Classifcation Basis Summary" conducted for Survey Unit 980 1-0000 consisted of:

a) A review of the 10CFR5O.75 (g) (1) database, b) A review of the "Initial Characterization Report" and the "Historic Site Assessment Supplement,"

c) Historic and current survey records review.

The radiological characterization of subsurface soil was conducted in this area to support decommissioning activities that commenced in 2002 and continued through 2006. Sampling activities were concentrated in several areas but the main area was designated as the "Big Dig" or Excavation #1, which was a large excavation that was immediately adjacent to the Reactor Building and constituted the surface Survey Units 93 12-0005 & 93 12-0006. Samples were acquired from the floor and walls of the excavation as part of the process to determine the effectiveness of the remediation effort in the subsurface.

Although the samples were collected from the surface of the excavations, they are considered suitable for subsurface soil characterization purposes because when the excavation was backfilled, the excavation floor and sidewall samples were indicative of the "as left" soil activity levels present in the subsurface.

Additional samples were collected in a similar fashion from the following areas within Survey Unit 9801-0000; the Decay Tank Excavation, the Spent Fuel Building (SFB) footprint, the Fuel Transfer Tube (FTT) excavation, the Spent Fuel Building East, Excavation #f5, the Containment Southeast, the Spent Fuel Building, Excavation #3, the Containment West, Excavation #6 and the RCA East trench. All soil samples were analyzed by an approved off-site laboratory for the gamma emitting radionuclides. Selected samples were analyzed for Hard-To-Detect (HTD) radionuclides. Cs- 137 was the predominant radionuclide detected in the sample population. Co-60 was also detected in the sample population. Additionally, Sr-90 was positively identified (i.e. a result greater than two (2) standard deviations uncertainty) in twenty-two (22) of forty-four (44) samples analyzed within this survey unit.

Revision 04 4

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 9801-0000 RELEASE RECORD During plant operation, Survey Unit 9312-0001 was the location of significant, radiologically contaminated structures and systems, namely the reactor, the reactor systems and the Containment structure. All contaminated systems and components, including the reactor vessel, were removed, appropriately packaged and shipped to an approved off-site disposal facility. The interior walls and floors within the Containment structure were demolished and removed. The Containment liner was removed with the exception of the Incore Sump. The dose from residual radioactivity on the remaining steel and concrete in the sump was accounted for in the "Basement Fill Dose Model". The Incore Sump was then filled with concrete "flow-able fill" to the basement floor elevation. The remaining interior surfaces inside the Containment shell were then decontaminated. Following decontamination, the Containment basement was backfilled to grade. The above grade portion of the Containment structure was then demolished and removed. Fill was then placed over the survey unit, raising the grade of the area by approximately four (4) feet.

Prior to remediation, significant soil contamination was present in and around this survey unit. Cs-137 was detected in soil samples at concentrations greater than two hundred (200) times its Operational Derived Concentration Guideline Level (DCGL); Co-60 was positively detected at a concentration twice its Operational DCGL and Sr-90 was positively identified at a concentration of 42%

of its DCGL. Outside of the containment shell, soil remediation began beneath and around each ancillary structure as each structure was demolished and removed and/or until bedrock was exposed. As with the Containment basement shell, all excavations were backfilled with soil material. Due to the fact that the current subsurface soils located in Survey Unit 9801-0000 is composed of essentially fill, the results of surface soil samples taken post-remediation and prior to backfill on the sidewalls of the remediated excavations were used to provide data with regard to types and quantities of radioactive material for the design of this survey.

In Survey Unit 9312-0001, post-remediation soil samples were taken under several Survey and Sampling Work Plans, including SSWP-05-06-00l, SSWP-05-08-002, SSWP-05-09-007 and SSWP-06-09-002. Thirty-eight (38) surface soil samples were collected from the sidewalls of various excavations in and around Survey Unit 93 12-0001 prior to backfill. All samples were collected and analyzed by gamma spectroscopy by an approved off-site laboratory. Eleven (11) of the thirty-eight (38) total samples collected were analyzed for "Hard-to-Detect" (HTD) radionuclides.

A review of this sample data shows Cs-137, Co-60 and Sr-90 to be the primary radionuclides of concern. Cs-137 was the predominant radionuclide over Co-60 and Sr-90 by a factor of 7 to 1. In one (1) sample, Cs-137 and Co-60 was detected in a concentration equivalent to 115% of the Operational DCGL incorporating the "sum of fractions". Additional remediation was performed at Revision 05 5

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD this location prior to backfill. A summary of the sample results are provided in Table 1.

The sample results were evaluated to assess the distribution of the detected radionuclides. The radionuclide distribution percentage for each sample in the population was calculated by dividing the concentration of each detected radionuclide by the total activity concentration in the sample, expressing the abundance of the specific nuclide in the sample compared against the total activity.

During plant operation, Survey Unit 9312-0002 was the location of significant, radiologically contaminated structures and systems, including the Spent Fuel Pool (SFP), the Spent Fuel Building (SFB), the "Bus 10" area and the northeastern quadrant of the 11I5kV Switchyard.

The Spent Fuel Building (SFB) was a concrete structure designed for the storage of new and spent fuel. It contained radiologically contaminated items and process equipment necessary for safe handling and storage of spent nuclear fuel. The Spent Fuel Pool (SFP) itself was located in the northern half of the SEB. The Bus 10 Pad was originally an outdoor staging area designed to function as a decontamination facility. The 115 kV Switchyard was situated outside the RCA just south of the Containment building. This area included two Station Service Transformers and the 115 kV Tie Breaker. Also, Bus 12 was located at the SW comner of the yard. In addition to these, there were several other transformers with associated power lines that extended beyond the switchyard area.

Revision 06 6

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD Major demolition and remediation activities began in 2002. All radioactive systems and components located inside the SFB were removed and building structural surfaces were decontaminated to ensure contamination levels were acceptable for controlled demolition. Confirmatory radiological surveys were performed throughout the demolition process. The SFP liner was removed and the exposed concrete was decontaminated. The structural concrete of the SFP and the SFB was then demolished to grade. The dose from residual radioactivity on the remaining below grade concrete footings and foundations from the SFP and SFB was accounted for in the "Basement Fill Dose Model".

Outside of the structures, remediation was performed on the soils surrounding the SFP and SFB. The analysis of samples taken of the soils located along the northwest corner of the SFB between the SFB and Containment structure indicated the presence of Cs-137 and Co-60 at concentrations up to 988 pCi/g and 1.20 pCi/g respectively. The presence of Sr-90 was also positively identified. Contamination was also identified in the soils to the south of the SFP as a result of SFB sump and cask wash-down pad leakage. In this area, a significant volume of contaminated soil that exhibited direct exposure rates was removed prior to commencing soil sampling for isotopic analysis. Remediation support samples taken of the remaining soils in this area exhibited radionuclide concentrations of up to 992 pCi/g Cs-137 and 86.4 pCi/g Co-60. The presence of Sr-90, Eu-154 and Am-241 in the soil were also positively identified. The soils in both of these areas were remediated to bedrock and the excavations were backfilled with clean soil following the performance of radiological assessments.

Soil remediation also occurred at the "Bus 10" area. Previous investigations had identified elevated levels of Cs-137 and Co-60 in the soils in this area.

Remediation was successful in this area prior to excavating to the beginning of the saturated zone or bedrock. The area was backfilled following the performance of a radiological assessment.

In Survey Unit 9312-0002, post-remediation soil samples were taken under several Survey and Sampling Work Plans, including SSWP-05-08-002, SSWP-05-09-007 and SSWP-06-09-004. Thirty-nine (39) surface soil samples were collected from the sidewalls of various excavations in and around Survey Unit 9312-0002 to support remediation and soil excavation prior to backfill. All samples were collected and analyzed by gamma spectroscopy by an approved off-site laboratory. Eight (8) of the thirty-nine (39) total samples collected were analyzed for "Hard-to-Detect" (HTD) radionuclides.

A review of this sample data shows that Cs-137 and Co-60 are the primary radionuclides of concern. These radionuclides were detected in twenty-six (26) of the thirty-nine (39) soil samples. In addition, Am-241 and Eu-154 were positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in two (2) of the samples in concentrations greater than 5% of their Revision 07 7

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD respective Operational DCGLs. A summary of the sample results are provided in Table 2.

In two (2) of the remediation support samples, Cs-137 and Co-60 was detected in concentrations greater than 100% of the Operational DCGL while incorporating the "sum of fractions". Additional remediation was performed at these sample locations prior to backfill. No HTD radionuclides were positively identified.

During plant operation, Survey Unit 9312-0003 was the location of significant reactor support structures and systems, including the southwestern corner of the Primary Auxillary Building (PAB), the Feed Water/Steam Penetration Building (FW/STM), the Shutdown Auxiliary Feed Pump House, the Demin Water Storage Tank (DWST), the Condensate Storage Tank (CST) and the northwestern quadrant of the 115kV Switchyard.

The PAB was a concrete structure designed to house systems containing radioactive materials. The building was designed to contain and control leakage occurring during routine operations as well as unusual conditions. With the exception of the service water, gas and air systems, the majority of the systems within the PAB were radiologically contaminated. The PAB also contained highly contaminated pipe trenches and pump pit areas. The lower level of the PAB under the boron recovery equipment was contaminated due to past spills involving evaporator bottoms. Contamination levels in several of these systems Revision 08 8

SUBSURFACE SOILS TN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 9801-0000 RELEASE RECORD were high enough to create high radiation areas in their vicinity. Most of the cubicles that contained maj or systems were posted as "Contaminated Areas" identifying the presence of loose radioactive contamination in these areas.

Radiological surveys performed during facility operations indicated beta/gamma contamination levels in the PAB at levels up to hundreds of thousands of dpm/ 100 cm 2. Alpha contamination was also present at levels up to several thousand-dpm/100 cm2 Radiation levels in the PAB ranged from less than five (5) mR/hr to up to several thousand mR/hr.

Historically, leaks were found at the junction between the steam generator blow down line and the service water discharge line beneath the floor of the PAB drumming room. On at least one occasion, a leak resulted in contamination of the soil beneath the drumming room floor.

The FW/STM Penetration Building or "Terry Turbine Building" was located directly to the west of the Containment Building location. The building had three (3) basic levels. The lower level room contained auxiliary Feedwater pumps and piping, the middle level room contained the main steam dump valves and the upper level rooms housed the main steam stop valves. An outside catwalk that connected this building to the Service Building was located directly above Main Steam and Feedwater piping. The upper level also served as the alternate access HP control point to the Containment Building during decommissioning. The FW/STM Penetration Building was maintained free of loose radioactive contamination during facility operation. Periodic radiological surveys were routinely performed to substantiate this radiological condition.

The Electric Shutdown Auxiliary Feed Pump House contained the Electric Shutdown Auxiliary Feed Pump and all above grade DWST piping. The building was an independent structure with outer aluminum siding, inner sheetrock walls, slightly tapered sheet metal roof, asphalt floor, a building exhaust ventilation and a concrete support base beneath the pump. No significant radiological events were identified regarding this building.

The Demin Water Storage Tank (DWST), Condensate Storage Tank (CST), as defined includes the "Demin Water Storage Tank TK-25-1A" and the "Condensate Storage Tank TK-25-IB."

The 115 kV Switchyard (#11 11)was situated outside the RCA just south of the Containment building. This area included two (2) Station Service Transformers (#

204 & #205) and the 115 kV Tie Breaker (#218). Also, Bus 12 (ff120) was located at the SW corner of the yard. In addition to these, there were several other transformers with associated power lines that extended beyond the switchyard area.

Revision 09 9

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD The DWST and the CST were located to the southwest of the Contaimnment Building in the northwest corner of the 115 kV Switchyard. Even though these tanks were designed to normally contain only non-radioactive water, there is a documented history of radiologically contaminated water occasionally being introduced into these systems. Events that have contributed to the introduction of contaminated water into these tanks were steam generator tube failures and misalignment of valves. Historical surveys in the vicinity of these tanks do not indicate radioactive contamination was >1000 dpmll 00cm 2 f3/y. During April 1999, a shallow monitoring well and a deep monitoring well on the west side of the DWST produced samples that showed positive results for tritium.

Major demolition and remediation activities in this area began in 2002. All radioactive systems and components located inside the PAB were removed and building structural surfaces were decontaminated to ensure contamination levels were acceptable for controlled demolition. Confirmatory radiological surveys were performed throughout the demolition process. The structural concrete of the PAB and FW/STM Penetration Building were then demolished to grade. The Electric Shutdown Auxiliary Feed Pump House, the DWST, the CST and the concrete base pads for all three (3) structures were completely demolished and removed. The dose from any residual radioactivity on the remaining below grade concrete footings and foundations were accounted for in the "Basement Fill Model".

Outside of the structures, remediation was performed on the soils surrounding the PAB. The excavation around the PAB footing was designated as Excavation #2; the excavation around the FW/STM Penetration Building was designated as Excavation #6 and the excavation adjacent to the Containment Building in the Southeast section of the survey unit was designated as Excavation #3. A significant volume of contaminated soil that exhibited direct exposure rates was removed prior to commencing soil sampling for isotopic analysis. Remediation support samples taken of the remaining soils in this area exhibited radionuclide concentrations of up to 5.46 pCi/g Cs-137 and 0.20 pCi/g Co-60. See the note provided in Table 5. The soils in all of these areas were remediated to bedrock and the excavations were backfilled following the performance of radiological assessments.

During plant operation, Survey Unit 9312-0005 was the location of several significant reactor support structures and systems, primarily consisting of a grouping of liquid and gas storage tanks referred to as the "Tank Farm" and the Spent Resin Facility. The Tank Farm was an asphalt covered area located to the northeast of the former location of the Containment structure where the Refueling Water Storage Tank (RWST), the Waste Test Tanks A & B, the Aerated Drains Holdup Tank (ADHUT), the Borated Waste Storage Tank (BWST) and the Recycle Test Tanks (RTT's) were located. In addition, the area also contained sub-grade covered and shielded pipe trenches that housed subsurface piping and Revision 0 10

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD conduit associated with the tanks and other adjacent support systems. The Resin Slurry and Ion Exchange Area included the "Ion Exchange Structure", the "Spent Resin Facility" and "Spent Resin Storage Facility". These facilities were located in the yard on the east side of the Tank Farm. All storage tanks, radioactive systems and components located in this area were removed and building structural surfaces were decontaminated to ensure contamination levels were acceptable for controlled demolition. Confirmatory radiological surveys were performed throughout the demolition process. The concrete pads for the tanks and structures were demolished and removed.

Extensive remediation was performed on the soils under and surrounding the Tank Farm. This excavation was designated as Excavation #1. A significant volume of contaminated soil that exhibited direct exposure rates was removed prior to commencing soil sampling for isotopic analysis. Soil samples taken in this area to support remediation continued to exhibit detectable concentrations of Cs-137, Co-60 and Sr-90. The soils in all of these areas were remediated to bedrock and the excavations were backfilled with clean soil following the performance of radiological assessments.

Post-remediation soil samples were taken under several Survey and Sampling Work Plans, including SSWP 05-06-006. Seven (7) surface soil samples were collected from the sidewalls of various excavations in and around Survey Unit 9312-0005 to support remediation and soil excavation prior to backfill. All samples were collected and analyzed by gamma spectroscopy by an approved off-site laboratory. All of the samples collected were analyzed for "Hard-to-Detect" (HTD) radionuclides.

A review of this sample data shows that Cs-137 and Co-60 are the primary radionuclides of concern. These radionuclides were detected in five (5) of the seven (7) soil samples. Cs-137 was the predominant radionuclide over Co-60 by a factor of sixteen (16) to one (1). Sr-90 was positively detected (i.e., a result greater than two (2) standard deviations uncertainty) in one (1) sample, but at a concentration of less than 5% of the Operational DCGL. A summary of the sample results for Cs-137 and Co-60 are provided in Table 3.

Outside of the structure, remediation was performed on the soils surrounding the PAB. The excavation around the PAB footing was designated as the "Big Dig".

A significant volume of contaminated soil that exhibited direct exposure rates was removed prior to commencing soil sampling for isotopic analysis. Soil samples taken in this area to support remediation continued to exhibit significant concentrations of Cs-137, Co-60 and Sr-90. The soils in all of these areas were remediated to bedrock and the excavations were backfilled with clean soil following the performance of radiological assessments.

Post-remediation soil samples were taken under several Survey and Sampling Work Plans, including SSWPs 05-06-00 1 and 05-06-006. Thirty-seven (37) surface soil samples were collected from the sidewalls of various excavations in and around Survey Unit 9312-0006 to support remediation and soil excavation prior to backfill. All samples were collected and analyzed by gamma spectroscopy by an approved off-site laboratory. Eighteen (18) of the thirty-seven (37) total samples collected were analyzed for "Hard-to-Detect" (HTD) radionuclides.

A review of this sample data shows that Cs- 137, Co-60 and Sr-90 are the primary radionuclides of concern. These radionuclides were detected in twenty (20) of the thirty-seven (37) soil samples. Cs-137 was the predominant radionuclide over Co-60 by a factor of ten (10) to one (1). Sr-90 was positively detected (i.e.,

a result greater than two (2) standard deviations uncertainty) in seven (7) samples at concentrations up to 20% of the Operational DCGL. In addition, other "Hard-Revision 0 12

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 9801-0000 RELEASE RECORD to-Detect" (HTD) radionuclides were also positively identified, but in concentrations less than 5% as a single isotope and 10% as an aggregate of their respective Operational DCGLs. A summary of the sample results are provided in Table 4.

Where the Operational DCGL was exceeded, additional remediation was conducted to reduce the contamination levels to below the Operational DCGL.

Based on the characterization and post-remediation sample results from each area within this survey unit, the radionuclides of concern are Cs-137, Co-60, Sr-90, Am-241, Eu-154 and H-3.

However, in the interest of conservatism, 100% of the subsurface soil samples taken in this survey unit were analyzed by an approved off-site laboratory for All radionuclides specified in Table 6. All radionuclides listed in Table 6 that are verified to be present in FSS samples were included in the assessment of data and incorporated into the decision process, as necessary.

3. DATA QUALITY OBJECTIVES (DQO)

FSS design and planning used the Data Quality Objective (DQO) process as described by the LTP, Procedure RPM 5. 1-11, "Preparation of Final Status Survey Plan," and the "Multi-Agency Radiation Survey and Site Investigation Manual" (MARSSIM). A summary of the main features of the DQO process are provided herein.

The DQO process incorporated hypothesis testing and probabilistic sampling distributions to control decision errors during data analysis. Hypothesis testing is a process based on the scientific method that compares a baseline condition to an alternate condition. The baseline condition is technically known as the null hypothesis. Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided for rejection. In designing the survey plan, the underlying assumption, or null hypothesis was that residual activity in the survey unit exceeded the release criteria. Rejection of the null hypothesis would indicate that residual activity within the survey unit does not exceed the release criteria. Therefore, the survey unit does satisfy the primary objective of the FSS plan.

The primary objective of the FSS plan was to demonstrate that the level of residual radioactivity in Survey Unit 980 1-0000 did not exceed the release criteria specified in the LTP and that the potential dose from residual radioactivity is As Low As Reasonably Achievable (ALARA).

A fundamental precursor to survey design is to establish a relationship between the release criteria and some measurable quantity. This is done through the development of DCGLs. The DCGLs represent average levels of radioactivity above background levels and are presented in terms of surface or mass activity concentrations. Chapter 6 of the LTP describes in detail the modeling used to develop the DCGLs for soil (called Base Case Soil DCGL), existing groundwater radioactivity and fuiture groundwater radioactivity that will be contributed by building basements and footings.

The DCGLs presented in Chapter 6 of the LTP were developed for exposures from three (3) components, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity. Equation 1 shows the mathematical relationship between the three (3) components and the total dose.

Equation 1 H Total=11Soil+HExistingGw + JFutureGW Revision 0 15

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD The total dose under the LIP criteria is twenty-five (25) mrem/yr Total Effective Dose Equivalent (TEDE) from all three (3) components. The allowable total dose under the Connecticut Department of Environmental Protection (CTDEP) radiological remediation standard for CY is nineteen (19) mremlyr TEDE. To satisfy both the LTP and CY CTDEP criteria, the dose from soil must be reduced when using the existing and future groundwater dose values discussed above.

This survey area is affected by existing groundwater (reference CY memo ISC 06-024). Therefore, the dose contribution from existing groundwater is bounded by two (2) mrem/yr TEDE.

This survey unit is considered impacted by future groundwater radioactive contamination, as there are underground foundations containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo LSC 06-024). The dose contribution from future groundwater, the third dose component, is bounded by two (2) mremlyr TEDE.

Equation 2 19 mrem/yrT0 ,aj = 15 mrem/yrsoil + 2 mremlyrrxisting GW+ 2 mrem1/yrFut~reGW The allowable dose for soil in this survey unit is fifteen (15) mrem/yr TEDE as shown by Equation 2 above. The concentration of residual radioactivity resulting in fifteen (15) mrem/yr TEDE is designated as the Operational DCGL, and has been established for the radionuclides of concern as provided in Table 6.

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 9801-0000 RELEASE RECORD Another important facet of the DQO process is to identify' the radionuclides of concern and determine the concentration variability. Based on the characterization and post remediation of the subsurface soils within this survey unit, Cs-137 and Co-60 were identified as the principle gamma emitting radionuclides which were present in sufficient concentrations that could potentially exceed the screening criteria. In addition, Sr-90, H-3, Am-241 and Eu- 154 were positively identified (i.e. a result greater than two (2) standard deviations uncertainty) in several samples.

As stated previously, 100% of the subsurface soil samples taken in this survey unit were analyzed by an approved off-site laboratory for All of the radionuclides specified in Table 1. All radionuclides listed in Table 1 that are verified to be present in FSS samples were included in the assessment of data and incorporated into the decision process, as necessary.

As part of the DQOs applied to laboratory processes, analysis results were reported as actual calculated results. Results reported as less than Minimum Detectable Concentration (MDC) were not accepted for FSS. Sample report summaries included unique sample identification, analytical method, radionuclide, result, and uncertainty to two (2) standard deviations, laboratory data qualifiers, units, and the required and observed MDC.

4. SURVEY DESIGN The level of effort associated with planning a survey is based on the complexity of the survey and nature of the hazards. Guidance for preparing FSS plans is provided in Procedure RPM 5. 1-11, "Preparationof Final Status Survey Plans".

The FSS plan uses a sample design that includes either random or biased media sampling.

The DQO process determined that Cs-137, Co-60, Sr-90, H-3, Am-241 and Eu-154 were the primary radionuclides of concern in Survey Unit 9801-0000.

However, all radionuclides positively identified at concentrations greater than the screening criteria during the performance of this FSS would also be evaluated to ensure adequate survey design. Radionuclide screening or de-selection is a process where an individual radionuclide or aggregates may be considered insignificant and eliminated from the FSS. The criteria for de-selection are concentrations less than 5% for individual radionuclides and less than 10% for aggregates.

As the survey unit is classified as a Class A subsurface soils area, and discrete, elevated areas of contamination were possible, the application of the Elevated Measurement Comparison (EMC) remained an option.

The Sign Test was selected as the non-parametric statistical test. The use of the Sign Test did not require the selection or use of a background reference area, which simplified survey design and implementation. This approach was conservative since it included background Cs-137 as part of the sample set.

Revision 0 18

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD LTP Section 5.7.3.2.2 states that for a Subsurface Class A area there shall be a minimum of thirty-one (3 1) measurement locations, 2based on a sample population of approximately one (1) per five hundred (500) mn in a Class A subsurface soil area. However, thirty-one (3 1) measurement locations over the surface area identified in this survey unit as approximately fifteen thousand seven hundred and eighty-eight (15,788) m2 would equate to one (1) sample every five hundred and nine (509) in . Since this ratio is larger than the ratio for a Class A subsurface area identified in the LTP, the minimum number of samples to be collected, within this survey unit, was increased to thirty-two (32) measurement locations. The sample density for Survey Unit 9801-0000 with a sample population of thirty-two (32) measurements over approximately fifteen thousand seven hundred and eighty-eight (15,788) m2ý is one (1) measurement every four hundred and ninety-three 2

(493) Mn . In addition, biased measurements or samples will be obtained at the locations of localized remediation efforts where subsurface leaks are suspected to have created soil contamination.

Additionally, LTP Section 5.7.3.2.2 states that the range of the number of measurements in Class A areas corresponds to the range of values for N (for Sign test), considering a = 0 .05, P1= 0.05, and a relative shift of < 3.0.

The grid pattern and locations of the soil samples were determined using Visual Sample Plan (VSP) in accordance with Procedure RPM 5.1-14, "Identifying, and Marking Surface Sample Locationsfor Final Status Survey." Visual Sample Plan was created by Pacific Northwest National Laboratory (PNINL) for the United States Department of Energy. A systematic triangular grid pattern with a random starting point was selected for sample design, which is appropriate for a Class A subsurface survey area.

Sample locations were identified using AutoCAD-LT, a commercially available plotting software package with coordinates consistent with the Connecticut State Plane System. These coordinates were integrated with a GPS to locate sample locations in the field. Sample Measurement Locations for the design are listed with the GPS coordinates in Table 7.

Therefore, addendum #1 to the FSSP was written and sample numbers 980 1-0000-040F, 9801-0000-041IF and 9801 -0000-042F were identified as replacement samples.

Revision 0 20

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD During the performance of the survey, it was discovered that three (3) of the thirty-two (32) sample locations identified for non-parametric testing were deemed to be inaccessible due to refusal of the direct push probe sampling technology (GeoProbeg) prior to retrieving the required amount of sample. The three (3) inaccessible locations identified were 9801-0000-OO1F, 9801-0000-002F and 9801-0000-004F. Subsequently, three (3) additional sample measurement locations were designated to replace the locations that were deemed to be inaccessible. The location of the samples were determined using Visual Sample Plan (VSP) in accordance with RPM 5.1-14, "Identifying and Marking Surface Sample Locationsfor FSS in Open Land Areas" using a random selection which is appropriate for relocating a small number of sample locations in a Class A area.

Sample Measurement Locations for the additional samples are listed with the GPS coordinates in Table 10.

In accordance with LTP Section 5.7.3.2.2, judgmental samples were identified as a part of the sample design.

The FSSP identified that a minimum of six (6) judgmental samples would be collected in this survey area. Three (3) judgmental samples were to be collected from the location referred to as the "Big Dig". An additional judgmental sample was to be collected from each one (1) of the following locations: North of Spent Fuel Building (SFB), south of SFB (Bus 10) and north of the Make-up Water Storage Tank (MWST) area. The general locations of the judgmental samples are illustrated on the Sample Location Map & Work Sheet and coordinates are provided in Table 8. Additional judgmental samples may be collected, at the discretion of the FSS Engineer.

()Judgmental sample # 9801-0000-038B was inaccessible because the random location selected was sixteen (16) feet up the mountain side. Therefore, addendum #1 to the FSSP was written and sample # 980 1-0000-039B was identified as a replacement sample location.

Addendum #1 to the FSSP was developed to identify both the three (3) replacement non-parametric statistical samples and the one (1) judgmental sample that were inaccessible. Table 9 identifies the replacement sample locations.

Procedure RPM 5.1-11 specifies that 5% of the samples are required to be selected for HTD analysis. However, in the interest of conservatism all thirty-eight (38) samples were sent off-site for a full suite analysis of the HTD radionuclides specified in the LTP, Table 2-12, "Radionuclides Potentially Presentat Haddam Neck Plant" and as provided in Table 6.

The implementation of quality control measures as referenced by Procedure RPM 5.1-24, "Split Sample Assessment for FinalStatus Survey," included the collection of two (2) soil sample for "split sample" analysis by the off-site laboratory. This location was selected randomly using the Microsoft Excel "RANDBETWEEN" function.

Survey Unit 980 1-0000 is a subsurface survey unit. Subsequently, no scanning was required.

For this Class A survey unit, the "Investigation Level" for soil sample measurement results are those levels specified in LTP, Table 5-8. Table 10 provides a synopsis of the survey design.

5. SURVEY IMPLEMENTATION Final status survey field activities were conducted in accordance with the FSSP and Addendum #1 to the FSSP for Survey Unit 9801-0000. Subsurface soil sampling was conducted in accordance with Site Excavation Permit # 2006-0007.

The FSS plan included a job safety analysis, a job planning checklist, a site excavation permit and related procedures for reference. Daily briefings were conducted to discuss the expectations for job performance and the safety aspects of the survey. The "Daily Survey Journal" was used to document field activities and other information pertaining to the FSS.

Measurement locations were identified in North American Datum (NAD) 1927 coordinates using GPS coordinates; sample locations were identified and marked with a surveyor's flag or paint for identification.

Thirty-eight (38) subsurface soil samples were collected and packaged in accordance with Haddam Neck Plant (HNP) Procedure RPM 5.1-3, "Collection of Sample Media for Final Status Survey" and FSS design. Samples were collected using GeoProbe.

Revision 0 23

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 9801-0000 RELEASE RECORD All samples were obtained to a depth of three (3) meters or refusal. Table I11 and Table 12 identified the depth of each sample in addition to the Cs-137, Co-60 and Sr-90 activity.

Samples were controlled, transported, stored, and transferred to the off-site laboratory using Chain-of-Custody (COC) protocol in accordance with Procedure RPM 5.1-5, "Chain of Custody for Final Status Survey Samples." The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC.

All thirty-eight (38), thirty-two (32) for non-parametric statistical testing and six (6) judgmental, samples were selected for gamma spectroscopic and HTD radionuclide analysis for the twenty site specific radionuclides of interest, identified in Table 6.

The implementation of survey specific quality control measures included the collection of two (2) samples (9801-0000-015F and 9801-0000-022F) for "split sample" analysis.

6. SURVEY RESULTS All field survey activities were conducted between March 28, 2007 and April 3, 2007.

The off-site laboratory employed for the radiological analyses of samples was General Engineering Laboratories, LLC. The laboratory analyzed the thirty-two (32) samples collected for non-parametric statistical testing, the associated field splits and the six (6) judgmental samples using gamma spectroscopy.

As stated in Section 4, the off-site laboratory processed all thirty-two (32) samples identified for non-parametric statistically testing for gamma spectroscopy and HTD analyses. Additionally, the six (6) judgmental samples were also analyzed by gamma spectroscopy and HTD for the radionuclides of interest. The requested analyses included alpha spectroscopy, gas proportional counting, and liquid scintillation depending on the radionuclide and the measurement method.

The criteria for de-selection of a radionuclide is a concentration that is less than 5% of the Operational DCGL for individual radionuclides and less than 10% of the Operational DCGLs for aggregates.

All analyses met the required MD)Cs.

Cs-137 was identified in seventeen (17) and Co-60 was identified in four (4) of the thirty-two (32) samples collected for non-parametric statistical testing.

Additionally, Cs-137 was identified in four (4) and Co-60 was not identified in any of the six (6) judgmental samples collected. The mean of the gamma spectroscopic analysis results for the sample population indicated that Cs-137 was present at levels approaching the concentrations of Cs- 137 found in soil at off-site Revision 0 24

One (1) push of GeoProbeg equals approximately four (4) feet of vertical depth.

Of the remaining radionuclides of concern, identified in Section 4, H-3, Eu-154 and Am-241 were positively detected (i.e., a result greater than two (2) standard deviations uncertainty) in one (1), none and five (5) of the thirty-eight (38) samples analyzed, respectively. Additionally, based on the sample results, all three radionuclides mentioned above met the criteria for de-selection of a radionuclide of concern. Therefore, H-3, Eu-154 and Am-241 were de-selected based on the criteria discussed in Section 4.

Of the remaining site specific radionuclides of interest, identified in Table 6, only Manganese-54 (Mn-54), Iron-55 (Fe-S 5), Niobium-94 (Nb-94), Silver-108 meta-stable (Ag-108m), Cesium-134 (Cs-134) and Plutonium-238 (Pu-238) were positively detected (i.e., a result greater than two (2) standard deviations uncertainty) in two (2), one (1), one (1), two (2), nine (9) and one (1) of the thirty-eight (38) samples analyzed, respectively. Based on the sample results, the de-selection of these radionuclides based on the criteria discussed in Section 4, was appropriate. A summary of the results of the remaining radionuclides of interest, from Table 6, is provided in Attachment 3.

The "sum-of-fractions" or "unity rule" is the mathematical test used to evaluate compliance with radiological criteria for license termination when more than one radionuclide has been determined to be potentially present. The unity rule is:

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 9801-0000 RELEASE RECORD

7. QUALITY CONTROL The off-site laboratory processed the split samples and performed gamma spectroscopic and HTD analyses. Two (2) of the thirty-two (32) non-parametric statistical samples, or 6.3%, of the samples were selected for analysis, which exceeds the 5% minimum required by the LTP. The data were evaluated using USNRC acceptance criteria specified in Inspection Procedure 84750 as detailed in HNP Procedure RPM 5.1-24, "Split Sample Assessment for FinalStatus Survey ".

Co-60 was not detected in sufficient quantities in the field split results at locations 9801-0000-013 or 9801-0000-022 to evaluate in accordance with procedure. Cs-137 was not detected in sufficient quantities in the field split results at location 9801-0000-013. Evaluation using the reported results for naturally occurring K-40 resulted in acceptable agreement between the field-split results at these locations.

The sample analysis vendor, GEL, maintains quality control and quality assurance plans as part of normal operation. Refer to Attachment 3 for data and data quality analysis results.

8. INVESTIGATIONS AND RESULTS No investigations were conducted within this survey unit.
9. REMEDIATION AND RESULTS Significant remediation activities occurred in this survey unit prior to FSS. All above grade and many below grade commodities and facility systems were removed and properly dispositioned. Contaminated soils were identified, excavated and removed as part of the numerous remediation projects which occurred in this survey area. All excavations were characterized and backfilled prior to performing FSS. As a byproduct of remediation activities, the ground area is comprised of barren dirt with no vegetation, and the soils have been graded relatively flat to the corresponding elevation of the survey units to the north and west. Health Physics TSD BCY-HP-0078, "ALARA Evaluation of Soil Remediation in Support of Final Status Survey, " determined that remediation beyond that required to meet the release criteria is unnecessary and that the remaining residual radioactivity in soil was ALARA.
10. CHANGES FROM THE FINAL STATUS SURVEY PLAN During the performance of the survey, it was discovered that three (3) of the thirty-two (32) sample locations identified for non-parametric testing and one (1) of the judgmental sample locations were deemed to be inaccessible. The four (4) locations identified were 9801-0000-OO1F, 9801-0000-002F, 9801-0000-004F and 9801-0000-038B. Subsequently, Addendum #1 to the FSSP was written and Revision 0 30

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD four (4) additional sample measurement locations (9801-0000-040F, 9801-0000-041F, 9801-0000-042F and 9801-0000-039B) were designated to replace the locations that were deemed to be inaccessible.

11. DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with Procedure RPM 5.1-23, "Data Quality Assessment, " for completeness and consistency.

The Sign Test was performed on the data and compared to the original assumptions of the DQOs. The evaluation of the Sign Test results demonstrates that the survey unit passes the unrestricted release criteria, thus, the null hypothesis is rejected.

Documentation was complete and legible. Surveys and sample collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly designated as Class A.

The preliminary data review consisted of calculating basic statistical quantities (e.g., mean, median, standard deviation). The mean and median values are well below the Operational DCCL.

Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs. The basic statistical quantities for the statistical sample population are provided below in Table 15.

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD For Cs-137, the range of the data, about four (4) standard deviations, was not a particularly large variation considering that the levels were essentially at existing environmental levels where such variation is to be expected. The difference between the mean and median was about 12% of the standard deviation which indicates some skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot indicates positive skewness as confirmed by the calculated skew of 3.96.

For Co-60, the range of the data, about five (5) standard deviations, was not a particularly large variation considering that the levels were essentially at existing environmental levels where such variation is to be expected. The difference between the mean and median was about 28% of the standard deviation which indicates some skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot indicates positive skewness as confirmed by the calculated skew of 4.39.

For Sr-90, the range of the data, about four (4) standard deviations, was not a particularly large variation considering that the levels were essentially at existing enviromnmental levels where such variation is to be expected. The difference between the mean and median was about 61% of the standard deviation which indicates some skewness in the data. The data was represented graphically through posting plots, a frequency plot, and a quantile plot. The frequency plot indicates positive skewness as confirmed by the calculated skew of 1.43.

The other radionuclides of concern, H1-3, Eu-154 and Am-241, although included in the FSS plan for compliance purposes, were positively identified (i.e., a result greater than two (2) standard deviations uncertainty) in one (1), none and five (5) of the thirty-two (32) samples collected for non-parametric statistical testing, respectively. H-3, Eu-154 and Am-241 were de-selected based on the criteria discussed in Section 4. Data assessment and graphical representation of these radionuclides was not considered useful given the limited number of data points to represent the distribution.

All data, assessments, and graphical representations are provided in Attachment 3.

12. ANOMALIES No anomalies were noted.
13. CONCLUSION Subsurface soil Survey Unit 980 1-0000 has met the final DQOs of the FSS plan.

The ALARA criteria for soils as specified in Chapter 4 of the LTP were achieved.

Elevated Measurement Comparison was not required.

For this survey unit, Cs-137, Co-60 and Sr-90 were used for statistical testing to determine the adequacy of the FSS.

Revision 0 332

SUBSURFACE SOILS IN THE RADIOLOGICALLY CONTROLLED AREA SURVEY UNIT 980 1-0000 RELEASE RECORD The sample data passed the Sign Test. The null hypothesis was rejected. The survey unit is properly designated as Class A.

Compass was not used to determine the adequacy of the survey unit because Survey Unit 9801-0000 is a subsurface Class A survey unit and that does not conform to the Compass model parameters. However, the survey unit meets the requirements established in LTP Section 5.7.3.2.2 which states that there will be a minimum of thirty-one (3 1) measurement locations, based on a sample population of approximately one (1) per five hundred (500) M2 in a Class A subsurface soil area. However, thirty-one (31) measurement locations over the surface area identified in this survey unit as approximately fifteen thousand seven hundred and eighty-eight (15,788) M2 would equate to one (1) sample every five hundred and nine (509) in . Since this ratio is larger than the ratio for a Class A subsurface area identified in the LTP, the minimum number of samples to be collected, within this survey unit, was increased to thirty-two (32) measurement locations.

The sample density for Survey Unit 9801-0000 with a sample population of thirty-two (32) measurements over approximately fifteen thousand seven hundred and eighty-eight (15,788) Mn2 is one (1) measurement every four hundred and ninety-three (493) in2 .

The dose contribution from soil is 0.52 inremlyr TEDE based on the average radionuclide concentrations in the samples used for non-parametric statistical sampling.

This survey area is affected by existing groundwater (reference CY memo ISC 06-024); therefore the dose contribution from existing groundwater is bounded at two (2) inreinlyr TEDE.

This survey unit is considered impacted by future groundwater radioactive contamination, as there are underground foundations containing residual radioactive material within the groundwater saturated zone in the area (reference CY memo ISC 06-024). The dose contribution from future groundwater, the third dose component, is bounded by two (2) mrem/yr TEDE.

The average total dose from residual radioactivity in this survey unit, including exposures from the three (3) components as described in Section 3, that is, residual radioactivity in soil, existing groundwater radioactivity, and future groundwater radioactivity from the burial of concrete foundations or footings from site buildings containing residual radioactivity, will not exceed 4.52 inremlyr TEDE. Therefore, Survey Unit 980 1-0000 is acceptable for unrestricted release.

Rick, On the attached COG 2007-00108, the collect date listed for samples 9801-0000-033B through -037B appear to be incorrect (late April) . Can you confirm that these should be March dates or send a corrected COC?
Thanks, Cheryl Rick E. Gault wrote:

Cheryl; We're sending 40 samples under MSR 07-0137 to GEL today. All of the samples have a 7 day TAT request. It is acceptable for GEL to use the traced/untraced Tc-99 process for these quick TAT requests. See attached COC for requested analyses.

Also if you could send up a few coolers for future shipments it would be appreciated, about 4 would be enough for now.

The Qualifiers in this report are defined as follows:

Analyte is a surrogate compound Result is less than value reported Result is greater than value reported A The TIC is a suspected aldol-condensation product B For General Chemistry and Organic analysis the target analyte was detected in the associated blank.

BD Results are either below the MDC or tracer recovery is low C Analyte has been confirmed by GC/MS analysis D Results are reported from a diluted aliquot of the sample H Analytical holding time was exceeded J Value is estimated N/A Spike recovery limits do not apply. Sample concentration exceeds spike concentration by 4X or more ND Analyte concentration is not detected above the detection limit R Sample results are rejected U Analyte was analyzed for, but not detected above the MDL, MDA, or LOD.

GEL LABORATORIES LLC 2040 Savage Road Charleston SC 29407 - (843) 556-8171 - www.gel.com QC Summary Workorder: 183607 Page 17 of 17 Parmname NOM Sample Qual QC Units RPD% REC% Range Anist Date Time Y

A RPD of sample and duplicate evaluated using +/-RL. Concentrations are <5X the RL h Preparation or preservation holding time was exceeded N/A indicates that spike recovery limits do not apply when sample concentration exceeds spike conc. by a factor of 4 or more.

    • Indicates analyte is a surrogate compound.

A The Relative Percent Difference (RPD) obtained from the sample duplicate (DUP) is evaluated against the acceptence criteria when the sample is greater than five times (5X) the contract required detection limit (RL). In cases where either the sample or duplicate value is less than 5X the RL, a control limit of +/- the RL is used to evaluate the DUP result.

For PS, PSD, and SDILT results, the values listed are the measured amounts, not final concentrations.

Where the analytical method has been performed under NELAP certification, the analysis has met all of the requirements of the NELAC standard unless qualified on the QC Summary.
