FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 10 of 354 1 Issue Statement This Radiological Characterization Report presents a description of the radiological characterization of impacted structures and open land areas at the Fort Calhoun Station (FCS)
Decommissioning Project. The characterization survey data was collected and evaluated in accordance with site procedures that dictate the site characterization program implemented by EnergySolutions. The scope and objectives of the characterization program and the staff organization that manages the program are described in FCSD-RA-LT-200, Characterization Survey Plan (Ref. 1).
2 Background The purpose of site characterization is to ensure that the Final Status Survey (FSS) will be conducted in all areas where contamination existed, remains, or has the potential to exist or remain.
Characterization incorporates the results of investigations and surveys conducted to quantify the extent and nature of contamination at the FCS site. The characterization focused on areas that will remain at the time of license termination to enable better planning for FSS and to verify initial survey unit classifications. The characterization survey also focused on structures, or portions of structures, that will be removed as part of the decommissioning process in order to better plan for the remediation or removal methodologies, evaluate disposal options, and to estimate costs.
During the site characterization, the surveys of many inaccessible or not readily accessible subsurface soils and structural surfaces have been deferred and will be surveyed at a later date as part of continuing characterization. Examples of these areas include underlying concrete of the Containment, Spent Fuel Pool, Transfer Canal, and portions of the Auxiliary Building; areas restricted by high dose rates or safety considerations; and interiors of embedded and buried pipe that may remain at the time of license termination. As access is gained to these areas, additional characterization data will be collected, evaluated, and presented in a revision to this report.
The characterization surveys were designed and executed using the guidance provided in NUREG-1575, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (Ref. 2) and NUREG-1757, Volume 2, Revision 1, Consolidated Decommissioning Guidance, Characterization, Survey and Determination of Radiological Criteria (Ref. 3). In addition, surveys were designed and executed in accordance with FCSD-RA-LT-200, Characterization Survey Plan and FCSD-RA-LT-100, Quality Assurance Project Plan for the License Termination Plan Development, Site Characterization and Final Status Survey Projects at Fort Calhoun Station (QAPP) (Ref. 4), which describes policy, organization, functional activities, the Data Quality Objective (DQO) process, and measures necessary to achieve quality data.
2.1 Site Description The FCS site is located on the west bank of the Missouri River at river mile 646.0 on 660.46 acres, approximately 19.4 miles north of Omaha, Nebraska. Omaha Public Power District (OPPD) has a perpetual easement on 582.18 acres of land primarily on the east bank of the river directly opposite the plant buildings, approximately 475 acres of which is located in Iowa. About 85% of the site is on relatively level ground located in the alluvial plain of the river. On the western part of the site the ground rises sharply about 60 feet to a higher, level area which is bounded on the west by SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 11 of 354 United States (US) Highway 75, formerly US Highway 73. In July of 2018, OPPD requested approval from the US Nuclear Regulatory Commission (NRC) to remove approximately 120 acres of land on the northwest portion of the owner-controlled area (identified as OPPD Land Leased to Local Farmers on Figure 1) from the Part 50 License. This partial site release was approved in September 2018. In November of 2018, OPPD submitted a request for partial site release of the 475-acre property in Iowa that was subject to a perpetual easement (see Figure 1), and the NRC approved the release in January of 2019.
FCS Unit 1 was a Combustion Engineering (CE) 2-loop pressurized water reactor rated at 479 megawatts electrical. The station is comprised of the CE pressurized water reactor with supporting facilities. The primary coolant system consisted of two heat transfer loops. Each loop contained one steam generator and two reactor coolant pumps with associated piping and valves. In addition, the primary coolant system included a pressurizer, pressurizer relief tank, interconnecting piping, and the instrumentation necessary for operational control. All major components of the primary coolant system are located within the Containment Building.
Plant construction began in 1966. The first fuel assembly was loaded into the reactor between May and June, 1973. The NRC issued an operating license on August 9, 1973 (NRC License No. DPR-40, Docket No. 50285). The plant officially went online on September 1, 1973, with commercial operation starting 25 days later. On June 24, 2016, and updated on August 25, 2016, FCS submitted the Certifications of Permanent Cessation of Power Operations in accordance with 10 CFR Part 50.82(a)(i). The plant went offline on October 24, 2016.

FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 13 of 354 2.2 Initial Survey Units and Classification 2.2.1 Survey Units The entire 566 acre FCS site was divided into preliminary survey units and assigned initial classifications based on operational history and the incidents and processes documented for a specific survey unit. The survey units established by FCSD-RA-LT-200, Characterization Survey Plan were used as initial survey units for characterization. A survey unit is a structure, portion of a structure, open land area, or system that is surveyed and evaluated as a single entity. Survey units were delineated to physical areas with similar operational history or similar potential for residual radioactivity. To the extent practical, survey units were established with relatively compact shapes, and highly irregular shapes were avoided unless the unusual shape was appropriate for the site operational history or the site topography. Additionally, survey unit sizes were established to adhere to the suggested sizes provided in MARSSIM. A summary of the initial survey unit classifications is presented in the following sections.
2.2.1.1 Class 1 Structures Table 1 below presents the Class 1 structures: the Containment Building, the Auxiliary Building, and the Radwaste Processing Building. The structures contain the nuclear reactor, primary reactor systems, reactor support systems, radioactive waste systems, and nuclear fuel handling and storage systems. During operations, radioactive material was routinely handled, transferred, and stored within these buildings.

The decommissioning approach for these structures involves the complete segmentation, removal, and disposal of all systems and structural surfaces, with the exception of the below-grade concrete and embedded systems, as waste. The floor, walls, and embedded systems that reside greater than three feet below grade in these structures will remain at site closure and be subjected to FSS.
2.2.1.2 Class 2 and 3 Structures The primary functions of the Class 2 and 3 structures are to house the secondary side steam systems or electrical generating systems, or to act as office, warehouse, or security space. Table 2 below presents a list of the Class 2 and 3 structures with relation to the FCS Deconstruction Area (DA),
formerly the Protected Area.

However, it was possible, due to their physical proximity to effluent release pathways, radioactive contamination of secondary side systems, temporary storage and transport of radioactive materials in and through these buildings, and past incidents involving the loss of control of radioactive material that residual radioactive material could be found in, on, or around these structures.
Consequently, the initial Class 2 or 3 designations are justified. As with the Class 1 structures, the decommissioning approach calls for the complete segmentation, removal, and disposal of all Class 2 or 3 systems and structural surfaces as waste or salvage, with the exception of the Intake Building, FLEX Building, and Training Center. With the exception of structural floors, walls, and embedded systems that reside three feet below grade and greater in the Intake Building, and the above-grade FLEX and Training Buildings, no portion of these structures will remain at site closure to be subjected to FSS. All of the structure survey units are depicted below in Figure 2.

The bases for the initial classification are the open land proximity to Class 1 structures within the DA, an overflow event in 1983, which was documented in the Historical Site Assessment for Fort Calhoun Station (HSA) (Ref. 5) and resulted in localized soil contamination outside the Auxiliary Building, and the location of the waste haul path and waste loadout structure.

Trained and experienced EnergySolutions and contractor personnel performed the characterization surveys in accordance with the protocols and process presented in FCSD-RA-LT-200, Characterization Survey Plan, using sample plan instructions and approved procedures.
3.1.1 Management EnergySolutions established the License Termination/Final Status Survey (LT/FSS) Group with sufficient management and technical resources to fulfill project objectives and goals. The LT/FSS Group is responsible for:
- site radiological characterization,
- License Termination Plan (LTP) development and implementation, and
- the performance of FSS.
Characterization and FSS encompasses all survey and sampling activities related to the LTP. This includes site characterization surveys, Unconditional Release Surveys (URS), Radiological Assessments (RA), Remedial Action Support Surveys (RASS), and FSS. The duties and responsibilities of key EnergySolutions managers as well as various key positions within the LT/FSS Group are provided in Section 3.3 of the QAPP.
3.1.2 Training Specific training for the implementation of characterization surveys was provided to personnel assigned to take measurements and collect samples for characterization. The training ensured that the personnel that acquired characterization survey data had sufficient knowledge to perform work activities in accordance with the requirements of FCSD-RA-LT-200, Characterization Survey Plan and survey instructions.
3.1.3 Procedures Characterization survey activities were conducted in accordance with approved procedures to ensure quality. These procedures are controlled and implemented in accordance with site programs. Procedures used to perform site characterization include the following:
- FCSD-RA-LT-201, Characterization Sample Plan Development (Ref. 6)

The characterization sample plan is controlled in accordance with the record quality requirements of the QAPP. Sample plans and their survey instructions were developed according to the guidance regarding field sampling plans for radiological surveys provided in MARSSIM. Sample plans contain survey instructions that describe the number, type, and location of measurements and material samples with the type of analyses to be performed. Direction is also provided for the selection of instruments, count times, instrument modes, survey methods, required documentation, action levels, investigation levels, background determination requirements, and other appropriate instructions. In conjunction with the survey instructions, survey data forms, indicating desired measurements, were prepared to assist in survey documentation.
Characterization sample plans were developed in accordance with FCSD-RA-LT-201, Characterization Sample Plan Development. During the performance of the survey, the sample plans were updated with the results of direct measurements as well as the results of any special surveys or sample analyses performed. A characterization sample plan typically contains the items listed below:
- detailed description of the survey unit
- photographs, maps, or drawings of the survey unit
- a summary of the operational history from the HSA pertinent to the survey unit SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 28 of 354
- summary data from any previous radiological surveys
- the specific DQOs for the survey unit
- types and number of survey measurements or samples prescribed for the survey
- specific survey instructions
- sample designation codes and locations
- quality assurance measures in accordance with the QAPP
- any additional pertinent information such as support from other groups, health and safety information, necessary work orders (e.g., for coring, drilling, excavation activities), and permits (e.g., excavation permit, radiation work permit) 3.3 Survey Measurement and Sample Identification Designations To facilitate data queries and reporting, each characterization survey measurement and sample collected was assigned a unique identification designation. The identification designation also provided for measurement traceability back to a specific location on a survey unit drawing and in the field. Table 6 below presents the sample and measurement unique identification designation system.

FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 30 of 354 3.4 Characterization Approach Site characterization of the FCS was performed in accordance with the FCSD-RA-LT-200, Characterization Survey Plan, which was developed to provide guidance and direction to the personnel responsible for designing and implementing characterization survey activities. FCSD-RA-LT-200, Characterization Survey Plan works in conjunction with implementing procedures and survey unit specific survey instructions (sample plans) that were developed to safely and effectively acquire the requisite characterization data.
Characterization data acquired through the execution of the sample plan was used to meet three primary objectives:
- Provide radiological inputs necessary for the design of FSS.
- Develop the required inputs for the LTP and dose assessments.
- Support the evaluation of remediation alternatives and technologies.
A significant study question that must be answered by the characterization is whether or not a survey unit is classified correctly. The appropriate classification of a survey unit is critical to the survey design for FSS. A classification which underestimates the potential for contamination could result in a survey design that does not obtain adequate information to demonstrate that the survey unit meets the release criteria. In some cases, this can increase the potential for making decision errors.
As site-specific DCGLs were not yet established for the FCS decommissioning at the time the characterization surveys were performed, alternate action levels were selected. The screening values presented in Tables H.1 and H.2 of NUREG-1757, Volume 2, Revision 1, Consolidated Decommissioning Guidance, Characterization, Survey and Determination of Radiological Criteria were selected as the alternate action levels.
As stated in the guidance, the models, scenarios, and parameters used to develop the screening values were intended to be conservative. The lack of information about a site warrants the use of conservative models and default conditions to ensure that the derived dose is not underestimated.
Subsequently, use of screening values as action levels during characterization provided reasonable assurance that a survey unit was conservatively classified. The screening values used for soil characterization at FCS are reproduced below in Table 7.
Table 7 - Soil Screening Values for Characterization Radionuclide Screening Value (pCi/g) Radionuclide Screening Value (pCi/g)

FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 31 of 354 For structures, the gross screening level that was used during characterization as an action level to evaluate the classification of survey units was the nuclide-specific screening value of 7,100 dpm/100cm2 total gross beta-gamma surface activity, based on Co-60 from NUREG-1757, Volume 2, Revision 1, Consolidated Decommissioning Guidance, Characterization, Survey and Determination of Radiological Criteria. The use of the Co-60 screening value was conservative, as it was anticipated that the radionuclide distribution for surface contamination would be principally Co-60 and Cs-137.
3.4.1 Potential Radionuclides of Concern FC-18-002, Potential Radionuclides of Concern During the Decommissioning of Fort Calhoun Station (Ref. 19) establishes the basis for an initial suite of potential Radionuclides of Concern (ROC) for decommissioning. Industry guidance was reviewed as well as the analytical results from the sampling of various media from past plant operations. Based on the elimination of some of the theoretical neutron activation products, noble gases, and radionuclides with a half-life less than two years, an initial suite of potential ROC for the decommissioning of the FCS was prepared. The list of potential radionuclides is listed below in Table 8.
Table 8 - Initial Suite of Radionuclides for the Decommissioning of Fort Calhoun Station Radionuclide Half-Life (years) Radionuclide Half-Life (years)
H-3 12.3 Cs-137 30.04 Fe-55 2.73 Pu-238 87.7 Co-60 5.27 Pu-239/240 24,110 Ni-63 100.1 Pu-241 14.4 Sr-90 28.74 Am-241 432.2 Cs-134 2.07 Cm-243/244 29.1 3.4.2 Data Quality Objectives DQOs were implemented for characterization surveys in a similar manner as anticipated for FSS.
However, the goal of characterization is contamination quantification and delineation of the nuclide suite, whereas the FSS goal is comparison of data against the null hypothesis of the Sign test as defined by MARSSIM. Characterization inspections and surveys of sufficient quality and quantity were performed to determine the nature, extent, and range of radioactive contamination in each applicable survey unit, including applicable structures, residues, soils, and surface water.
The seven steps in the DQO development process are as follows:
- 1) state the problem
- 2) identify the decision
- 3) identify inputs to the decision
- 4) define the study boundaries SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 32 of 354
- 5) develop a decision rule
- 6) specify limits on decision errors
- 7) optimize the design for obtaining data The DQOs for site characterization included identifying the types and quantities of media to collect. Soils and structural concrete were sampled volumetrically. Sufficient measurements were obtained to achieve statistically significant results so that the mean and maximum activity, as well as the sample standard deviation, could be determined. Direct measurements and scans of structural surfaces and surface soils were also made using the same instruments and Minimal Detectable Concentrations (MDCs) as will be employed for FSS. Volumetric samples that exhibited the highest activity were sent to an off-site laboratory for analysis of (Hard-to-Detect)
HTD radionuclides.
3.4.3 Survey Design Characterization surveys were designed and performed in accordance with all applicable, approved procedures and FCSD-RA-LT-200, Characterization Survey Plan. Survey design incorporated a graded approach based upon the DQOs for each survey unit.
There are three approaches used for survey design: judgmental (biased), systematic, or random.
Judgmental survey designs use known information or process knowledge to select locations for static measurements or samples. Systematic survey design, usually only utilized for FSS, selects static measurement or sample locations by using a systematic sampling design (typically a square or triangular grid) with a random start. Random survey design selects static measurements or sample locations randomly. The decision of whether to perform survey design using a judgmental, systematic, or random approach was addressed by the DQO process. A judgmental approach was warranted when the characterization effort was designed to delineate the extent of an area that requires remediation. Alternatively, a systematic or random approach was warranted if the characterization effort was designed to verify the basis for classification. Most characterization surveys utilize a combination of random and judgmental approaches to survey design.
3.4.3.1 Number of Static Measurements or Samples The number of measurements or samples that were taken in each survey unit was determined by assessing the population size necessary to satisfy the DQOs.
For the characterization of Class 1 survey units, the number of static measurements or samples were of sufficient quantity to satisfy the DQO decision in the professional judgment of the responsible LT/FSS Specialist.
For the characterization of Class 2 survey units, the minimum number of systematic or random static measurements or samples taken in the survey unit were commensurate with the probability of the presence of residual radioactive contamination in the survey unit. The sample size selected was sufficiently robust to provide a statistically defensible mean and assessment of variability.
For Class 3 survey units, the primary characterization DQO is to establish the basis for the Class 3 or non-impacted classification. Consequently, the population of random measurements or samples was sufficiently robust so that the basis for the classification presented a high degree of confidence SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 33 of 354 that no licensee-generated radioactive material resides in these areas. Since the recommended survey unit size for a Class 3 is unlimited, additional measurements or samples above the minimum population calculated may have be necessary to address this DQO.
Table 9 provides the recommended judgmental and random measurement or sample population sizes. These are recommended sample population sizes; the actual number of judgmental and random measurements or samples collected in a survey unit was at the discretion of the responsible LT/FSS Specialist.
Table 9 - Recommended Sample Population Size Classification Population Type Recommended Population Size Judgmental 8 Class 1 Random Not required Judgmental 30 Class 2 Random 15 Judgmental 13 Class 3 Random 14 3.4.3.2 Determination of Survey Locations For impacted survey units, the location of measurements or samples to be taken in each survey unit (or group of survey units with similar geography and classification) was be determined by the responsible LT/FSS Specialist. For judgmental measurement or sample locations, consideration was be given to locations that exhibited measurable radioactivity (identified during the scan survey), depressions, discolored areas, cracks, low point gravity drain points, actual and potential spill locations, or areas where the ground had been disturbed. Historical information found in the HSA aided in judgmental location selection.
For Class 1 survey units, the location of measurements or samples was biased to suspect areas. For Class 2 and 3 survey units, the location of measurements or samples was chosen at random and augmented with biased measurements or samples, as necessary. Sample locations were determined by generating random pairs of coordinates that correspond to specific locations within a survey unit. This was accomplished through the use of a random number generator or through the use of the computer software Visual Sample Plan.
3.4.3.3 Scan Coverage Survey units were scanned in accordance with their classification. The area scanned in each survey unit was determined by the professional judgment of the responsible LT/FSS Specialist during the survey design process. Table 10 is a list of recommended scan coverage guidelines that were used.

5% to 50%, with emphasis on areas that were used for plant activities during Class 3 operation and areas downwind or downstream of known effluent release points 3.4.4 Types of Measurements or Samples The characterization survey of building or piping surfaces consisted of surface scans (beta and gamma), static beta measurements, material samples, and smears. The characterization survey of any concrete or asphalt-paved open land area consisted of surface scans (beta and gamma), static beta measurements, and volumetric samples. The characterization survey of the open land areas consisted of gamma scans and the sampling of surface and subsurface soil, sediment, and surface water for isotopic analysis. The following is a description of the different types of measurements and samples that were utilized.
3.4.4.1 Static Measurements Static measurements were performed to detect direct levels of total surface contamination on structural surfaces of the buildings or on concrete or asphalt paved areas. These measurements were performed using a 126 cm2 scintillation detector, the Ludlum Model 44-116.
Static measurements were conducted by placing the detector on or very near the surface to be counted and acquiring data over a pre-determined count time. A count time of one minute was typically used for surface measurements and generally provides detection levels well below the action level. Instrument count times could be adjusted, as appropriate, to achieve an acceptable MDC for static measurements.
3.4.4.2 Beta Surface Scans Scanning was performed in order to locate areas of residual activity above the investigation level.
Beta scans were performed over accessible structural surfaces including, but not limited to, floors, walls, ceilings, roofs, asphalt, and concrete paved areas. Hand-held beta scintillation detectors (i.e.,
Ludlum Model 44-116) were used for beta surface scans.
Beta scanning was performed with the detector position maintained within 1.27 cm (0.5 inch) of the surface and with a scanning speed of one detector active window per second. If surface conditions prevented scanning at the specified distance, the detection sensitivity for an alternate distance was determined, and the scanning technique adjusted accordingly. Scanning speed is calculated a priori to ensure the MDC for scanning was appropriate for the stated objective of the survey. Adjustments to scan speed and distance could be made when necessary.
SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 35 of 354 Technicians monitored the audible response of the survey instrument to identify locations of elevated activity that required further evaluation. All areas of elevated contamination located during scan surveys were identified for further investigation.
3.4.4.3 Gamma Surface Scans Gamma scans were performed over open land surfaces to identify locations of residual surface activity. Sodium iodide (NaI) gamma scintillation detectors (i.e., Ludlum Model 44-10) were used for these scans. FC-19-006, Ludlum Model 44-10 Detector Sensitivity (Ref. 20) examines the response and scan MDC of the Ludlum Model 44-10 NaI detectors to Co-60 and Cs-137 radionuclides when used for scanning surface soils.
Scanning was performed by moving the detector in a serpentine pattern, while advancing at a rate not to exceed 0.5 m (20 in) per second. The distance between the detector and the surface was maintained within 7.5 cm (3 in) of the surface. Audible signals were monitored, and locations of elevated direct levels were flagged for further investigation.
3.4.4.4 Removable Surface Contamination If applicable, removable beta contamination or smear surveys were performed to verify that loose surface contamination was less than the action level. A 100 cm2 surface area was wiped with a circular cloth or paper filter, using moderate pressure. Smears were then analyzed for the presence of gross beta and gross alpha activity. Counting was performed using a proportional counting system or equivalent.
3.4.4.5 Concrete Sampling Volumetric sampling of concrete, as opposed to static measurements, was necessary when gross static measurements were not sufficient to address the survey unit specific DQOs. As an alternative to core boring, a patented procedure that uses a hollow drill bit was used to obtain exact volumes of concrete material at certain depths while utilizing a vacuum collection system. Material from each of the incremental depths at a location were captured in a separate container for each depth increment via use of the vacuum system.
3.4.4.6 Material Sampling Samples of soil and sediment were obtained from designed judgmental, randomly selected, or systematic sample locations, as well as other biased locations in areas exhibiting elevated activity that were identified by scanning. Surface soil is usually defined as the top 15 cm (6 in) layer of soil, while subsurface soil is usually defined as soil below the top 15 cm layer in 1 m increments.
Surface soil was collected using a split spoon sampling system or by using hand trowels, bucket augers, or other suitable sampling tools.
Subsurface soil was sampled by direct push sampling systems (i.e., Geoprobe) or by the use of hand augers. Subsurface soil sampling was performed, as necessary, to address the DQOs for the survey unit.
An adequate amount of material (may range from 0.5 liters up to two liters) was collected at each location. Sample preparation included the removal of extraneous material and the homogenization SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 36 of 354 and drying of the soil for analysis. Separate containers were used for each sample, and accountability for each container was present throughout the analysis process as specified in the QAPP. Samples were split as specified in the QAPP when required.
3.4.5 Instrument Selection, Use, and Minimum Detectable Concentrations The radiation detection and measurement instrumentation for characterization was selected to provide both reliable operation and adequate sensitivity to detect the ROC identified for the decommissioning of the FCS at levels sufficiently below the established action levels. Detector selection was based on detection sensitivity, operating characteristics, and expected performance in the field. In all cases, the instruments and detectors selected for static measurements and analysis were capable of detecting the anticipated ROC at an MDC of 50% of the applicable action level.
Commercially available portable and laboratory instruments and detectors were used to perform the three basic survey measurements: (1) surface scanning, (2) static measurements, and (3) analysis of material samples.
Instrumentation and nominal MDC values that were employed during characterization are listed in Table 11 below. As the project proceeds, other measurement instruments or technologies, such as continuous data collection scan devices, may be added.

The calibration of instruments used for characterization is addressed in Section 4.7 of the QAPP.
3.4.5.2 Instrument Use and Control The receipt, inspection, issue, controls, and accountability of portable radiological instrumentation used for characterization is performed in accordance with the procedure that governs the issue, control, and accountability of characterization and FSS portable radiological instrumentation. The issue and control of instruments used for characterization is addressed in Section 4.6 of the QAPP.
3.4.5.3 Laboratory Instrument Methods and Sensitivities Gamma spectropscopy was primarily performed by the on-site radiological laboratory. Gas proportional counting and liquid scintillation analysis was performed by an approved vendor laboratory, GEL Laboratories, in accordance with approved laboratory procedures.
EnergySolutions ensured that quality programs of the contracted off-site vendor laboratories that were used for the receipt, preparation, and analysis of characterization samples provided the same level of quality as the on-site laboratory under the QAPP.
In all cases, analytical methods were established to ensure that required MDC values were achieved. The analysis of radiological contaminants used standard approved and generally accepted methodologies or other comparable methodologies. Table 12 below provides the analytical methods employed and the typical laboratory MDCs achieved by GEL Laboratories.

Laboratory quality for sample analyses taken to support characterization and FSS is discussed in NUREG-1576, Multi-Agency Radiological Laboratory analytical Protocols Manual (MARLAP) (Ref. 23) and Regulatory Guide 4.15, Quality Assurance of Radiological Monitoring Programs (Inception through Normal Operations to License Termination) - Effluent Streams and the Environment SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 39 of 354 (Ref. 24). Further, MARSSIM and MARLAP both indicate that a QAPP may be used in addition to, or in lieu of, existing quality systems to ensure data quality is achieved.
The QAPP was prepared and implemented to ensure the adequacy of data being developed and used during the site characterization and FSS process. The QAPP describes policy, organization, functional activities, the DQO process, and measures necessary to achieve quality data. It supplements the quality requirements and quality concepts presented in DD-QA-PN-006, QA Program Implementation Plan for the Fort Calhoun Decomissioning Services (Ref. 25), which adequately encompass other risk-significant decommissioning activities.
All characterization activities essential to data quality were implemented and performed using approved procedures. The effective implementation of characterization was verified through audit and surveillance activities, including field walk-downs by LT/FSS management and program self-assessments, as appropriate. Corrective actions were prescribed, implemented, and verified when deficiencies were identified. These measures applied to any applicable services provided by off-site vendors, as well as on-site subcontractors.
FCSD-RA-LT-200, Characterization Survey Plan was developed according to the essential elements of the quality assurance and quality control (QA/QC) program for the decommissioning of FCS and is subject to the QAPP. The QA/QC program elements applicable to characterization are as follows:
- establishment and implementation of plans, procedures, and protocols for field operations
- actions to ensure that the procedures are understood and followed by the implementing staff
- documentation of the data collected Details of the QA/QC elements specific to characterization are presented in the QAPP as well as the procedures and sample plan instructions. Characterization operations and the associated data acquisition and recording was guided and conducted in compliance with these QA/QC requirements. The specific QA/QC program components for site characterization are as follows:
- personnel qualifications, experience, and training
- execution in accordance with approved procedures
- proper documentation of survey data and sample analyses
- selection of appropriate instruments to perform the surveys
- proper instrument calibration and daily functional checks
- management oversight of characterization activities relative to the adherence to procedures, protocols, and documentation requirements 3.5 Characterization Implementation When a sample plan was approved, and prior to implementation, a pre-survey briefing was held with the LT/FSS Supervisors, LT/FSS Specialist, LT/FSS Instrumentation Specialist, Technicians who were assigned to perform the survey, and the supporting laborers. During the briefing, the SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 40 of 354 survey instructions were reviewed, and the technicians and laborers were provided with the necessary information required to assemble and stage all equipment and instruments necessary to perform the survey in accordance with the survey instructions.
Sample plan implementation included the following:
- setting up the survey instrumentation
- checking source and background radiation before and after each shift to ensure proper operation
- performing preliminary inspections of the areas to be surveyed to identify any additional specific survey requirements
- locating and marking static measurement and sample locations using the coordinates provided in the survey instructions
- collecting survey measurements
- analyzing samples using appropriate calibrated instruments
- documenting survey measurements and sample analysis data collected during characterization and placing the documentation in the survey unit package
- reviewing completed sample plans to ensure that all required surveys have been performed
- reviewing survey results to identify any areas exceeding the specified action levels 3.5.1 Survey Unit Preparation Preparation for characterization was performed in all survey units as deemed appropriate. Prior to performing characterization surveys on structural surfaces, the rooms were cleared to the extent possible of all loose equipment and materials. Survey equipment was staged and used in accordance with the OPPD Safety Manual (Ref. 26) to safely access structural surfaces greater than 6 feet above a normal walking surface. Open land survey units were cleared of debris and vegetation, to the extent possible, to eliminate physical obstructions prior to performing characterization surveys. Vegetation was cut as close to the ground surface as possible. All physical hazards in the survey units were either identified and removed or marked as appropriate.
In order to facilitate the selection of survey locations, a reference coordinate system was established. Reference coordinates provided a mechanism for identifying the location of a static measurement or sample and ensured that the survey location was reproducible. For open land survey units, reference coordinates were acquired using a Global Positioning System (GPS) coupled with the North American Datum standard topographical grid coordinate system. For structure survey units, a coordinate system (in meters) based on local origin points was established in each to facilitate the selection of survey locations.
3.5.2 Survey Unit Walk-Down Sample plan development began with the performance of a walk-down of the survey unit. During the walk-down, details regarding the physical nature of the survey area were compiled, such as the SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 41 of 354 different media requiring analysis, survey area dimensions, and actual or potential hazards. Data from available operational surveys were reviewed and utilized as appropriate.
Significant health and safety concerns include the potential industrial hazards commonly found at a construction site, such as exposed electrical circuitry, excavations, enclosed work spaces, hazardous atmospheres, insects, venomous snakes, plants, animals, unstable surfaces, heat and cold, sharp objects or surfaces, falling objects, tripping hazards, and working at heights. The pre-survey walk-down identified potential industrial safety hazards specific to the survey unit. This inspection identified general safety hazards as well as significant industrial safety hazards that could impact the performance of the survey.
Each identified hazard was evaluated to determine if the hazard could be mitigated, as well as to determine if the need for additional outside support or expertise was necessary to complete further evaluation. If, during the inspection or the performance of the subsequent survey, a serious hazard was identified that required immediate action (i.e., cannot be immediately eliminated, avoided, or minimized), then the area was isolated until an acceptable remedy was implemented.
3.5.3 Health and Safety Considerations The OPPD Safety Manual was developed to identify and mitigate health and safety concerns while performing activities. The OPPD Safety Manual and implementing procedures for job safety analysis meet the requirements for health and safety evaluation prior to commencement of work as specified in Section 4.10 of MARSSIM.
All characterization sampling and surveys were performed in accordance with the OPPD Safety Manual. Hazards and applicable health and safety requirements were identified through Task Hazard Assessments, Job Hazard Analyses, and pre-job briefings. For entry and work in posted radiologically controlled areas, characterization activities were also conducted under an approved Radiation Work Permit, in which the characterization activities were described in sufficient detail to identify any applicable radiation protection and As Low as Reasonably Achievable (ALARA) requirements.
3.5.4 Survey Documentation Records of characterization surveys are maintained in the survey packages for each survey unit.
The survey package could include the following records depending upon the survey design and DQOs.
- survey unit diagram or drawing which includes depictions of boundaries, landmarks, and measurement and sample locations
- photographs of the survey area, as necessary, to show unique conditions
- printout of laboratory analysis results reported in appropriate units
- hand-logged or downloaded data files with measurement results converted to appropriate units for all static surface contamination measurements
- alpha and beta smear counter logged results or data files with measurement results converted to appropriate units for all removable surface contamination measurements SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 42 of 354 Digital photographs were employed in some cases to provide a more permanent record of the survey locations within a survey unit. When used, these photographic records were linked to landmark and directional information whenever possible.
3.5.5 Data Validation Characterization survey measurement and analysis results were reviewed to ensure that the survey was complete, fully documented, and technically acceptable. Validation ensured that the data set was comprised of qualified measurement results collected in accordance with the survey design, which accurately reflected the radiological status of the survey unit. The review criteria for data acceptability included the following items:
- The survey was in compliance with survey instructions as specified in the sample plan.
- MDCs were appropriate for the instruments and techniques used to perform the survey.
- Instrument calibration was current and traceable to NIST standards.
- The field instruments were source checked with satisfactory results before and after use each day that the data was collected, or if unsatisfactory, data obtained with that instrument since its previous acceptable performance check was evaluated for acceptability.
- The survey methods used to collect data was proper for the types of radiation involved and for the media being surveyed.
- The data set is comprised of qualified measurement results collected in accordance with the survey design, which accurately reflects the radiological status of the survey unit.
- The data has been properly recorded.
If the data review criteria was not met, then the LT/FSS Manager was informed. The discrepancy was reviewed, and the decision to accept or reject the data was documented in the survey package.
3.5.6 Data Evaluation and Review Static beta-gamma measurements collected during the characterization surveys were compared against the action levels. Material sample analysis results were compared against the volumetric action level values. If multiple ROC were identified in concentrations greater than MDC, then the unity rule was applied. In Class 3 survey units, individual survey results exceeding 50% of the action level were flagged. Survey results that approached or exceeded the action level were considered as cause for additional investigation or possible reclassification. As applicable, the mean activity and the standard deviation were calculated for the survey population.
At the completion of the surveys conducted in each survey unit, measurement results were assessed and evaluated according the DQOs. If the lateral extent of contaminated areas had not been determined by the measurements prescribed in the sample plan instructions, more measurements were taken to bound the extent of the surface contamination. Locations where the final depth of subsurface contamination could not be determined during the initial site characterization will be revisited during continuing characterization. The guidance provided in MARSSIM for survey, measurement, data analysis, and data evaluation according to the survey DQOs process was SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 43 of 354 repeated during the data evaluation. Once all DQOs had been achieved, the characterization was considered complete.
4 Assumptions No assumptions were made for this report.
5 Results Site characterization surveys commenced in November 2019 with the concrete sampling of the structures inside of the DA. In January 2020, characterization of the open land survey units commenced. Throughout 2019 and 2020, characterization activities were performed in parallel with dry fuel storage, radioactive commodity removal, and radioactive waste shipment activities at FCS. Consequently, access to certain areas to collect meaningful characterization survey data was prohibited. In these cases, characterization has been deferred until such time that radiological or physical conditions would allow for substantial survey. Characterization surveys (continuing characterization) will continue throughout the decommissioning process.
5.1 Volumetric Concrete Sampling In November and December of 2019, EnergySolutions contracted New Millennium Nuclear Technologies International, Inc. (NMNT International) to collect volumetric concrete samples using their proprietary TruPro technology, which utilizes hollow-bit drilling as an effective alternative to traditional core boring. All of the buildings inside of the DA (see Tables 1 and 2) were subject to volumetric concrete characterization, with primary focus on the Containment and Auxiliary Buildings. In total, 744 concrete samples were analyzed using the on-site gamma spectroscopy system. Tables A.1 and A.2 summarize the locations and numbers of concrete samples collected for site characterization.
The locations selected for the concrete sampling were biased towards areas with elevated dose rates, count rates, proximity to radiological components, or by visual observations of floor and wall surfaces that indicated potential contamination (e.g., discoloration or standing water). The goal was to identify, to the extent possible, the locations that exhibited the highest potential of contamination representing the worst case bounding radiological condition for concrete. This judgmental sampling approach also ensured there was sufficient source term in the samples to achieve the sensitivities required to determine the radionuclide distributions of gamma emitters as well as HTD radionuclides.
Using the TruPro technology, NMNT International was able to collect a total of 810 samples from 178 locations. Specific locations were identified for sampling to 1.5-inch depth or 6-inch depth.
For a location specified to be 1.5 inches in depth, three samples increments (each representing 0.5 inches in depth) were collected. For a location specified to be 6 inches in depth, 6 sample increments (the first four were 0.5 inches deep, then the next two were 2 inches deep) were collected. The tubes, drill bits, and sample containers were changed out for each new increment obtained, ensuring that no cross-contamination occurred.
SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 44 of 354 Sample increments were counted starting with the top-most increment, and increments of a sample location were analyzed until all ROC were less than MDC. Because this was the case, only 744 of the total 810 concrete samples collected were counted by the on-site gamma spectroscopy system.

5.2 Open Land Area Soil Sampling and Scanning Each surface and subsurface soil sample was analyzed by the on-site gamma spectroscopy system.
Analysis count times were adjusted as necessary to achieve an MDC equal to or less than 0.5 pCi/g for Cs-137 and Co-60. In accordance with FCSD-RA-LT-201, Characterization Sample Plan Development, a minimum of 10 percent of the soil samples were sent off-site to GEL Laboratories for full suite ROC analysis.
5.2.1 Survey Results for Class 3 Open Land Survey Units The Class 3 open land areas at FCS total 2,102,462 m2 of surface area. The Class 3 open land surface area was broken into three survey units in accordance with the area descriptions, sizes, and boundaries presented in FCSD-RA-LT-200, Characterization Survey Plan. The Class 3 open land survey units are illustrated by Figure 6.
5.2.1.1 Survey Unit 8100 Class 3 open land survey unit 8100 is located in the northern area of the site, with a total size of 867,259 m2. Additionally, survey unit 8100 is broken up into 10 smaller sub-units (8101-8110),
mainly consisting of farmland, wetlands, and a creek, and houses the Firing Range, Storage Shed, and the Switchyard.
The survey design for survey unit 8100 called for the acquisition of 39 judgmental surface soil samples and 42 random surface soil samples. Approximately 5% of the total surface area in the SRRS - 2B.134, DTC - RPA907
FC-20-012 Revision 0 FCS Decommissioning Project Radiological Characterization Report Page 46 of 354 survey unit, 43,363 m2, was scanned using a Ludlum Model 2221 instrument coupled to a Ludlum Model 44-10 NaI detector.
