SURVEY UNITS 05119A & 05119B

1. EXECUTIVE

SUMMARY

This Final Radiation Survey (FRS) Release Record for survey unit 05119, Auxiliary Building 542 ft. elevation embedded equipment and floor drain pipe, has been generated for the Zion Station Restoration Project (ZSRP) in accordance with ZionSolutions procedure ZS-LT-300-001-005, "Final Radiation Survey Data Reporting" and satisfies the requirements of Section 5.11 of the ZSRP License Termination Plan (LTP).

Because of differences in conceptual models and source terms, FRS at ZSRP has two different approaches depending on the media; (1) a Final Status Survey (FSS) is conducted on soil, buried piping and groundwater to demonstrate that residual radionuclide concentrations are equal to or below site-specific Derived Concentration Guideline Levels (DCGL), and (2) a Source Term Survey (STS) is conducted to' demonstrate that the inventory of residual radioactivity in building basements, embedded piping and penetrations is below a source term inventory commensurate with the dose criterion in 10 CFR 20.1402.

For STS, building-specific Basement Dose Factors (BDF) were calculated in units of mrem/yr per mCi. The residual radioactivity inventory remaining for each radionuclide-of-concem (ROC) is multiplied by the BDF for each radionuclide to calculate the actual dose from the remaining source term. Due to the presence of multiple ROC, the dose contribution from each ROC is accounted for using the sum-of-fractions (SOF) to ensure that the total dose from all ROC does not exceed the dose criterion. To support STS implementation, the BDFs for all ROC are converted to Basement Inventory Levels (BIL) in accordance with ZSRP LTP section 5.5.2.1.

Two (2) STS packages (STS Sample Plans Sl-05119A-S and Sl-05119B-S) were developed* in accordance with ZionSolutions procedure ZS-LT-300-001-001, "Final Radiation Survey Package Development," the ZSRP L TP, and guidance from NUREG-1575, Revision 1, "Multi-Agency Radiation Survey and Site Investigation Manual" (MARS SIM).

The Auxiliary Building 542 ft. elevation embedded equipment and floor drain pipe are classified as STS Class 1. The Auxiliary Building 542 ft. elevation embedded equipment and floor drain pipe are part of the Auxiliary Building STS basement. In accordance with LTP section 5.5.4, in situations where there are multiple survey units in a STS basement, a fraction of the BIL is allocated to each survey unit. The sum-of-fraction for each ROC is calculated by dividing the reported activity level by an allocated fraction of the applicable BIL, which equates to the upper bound of the gray region for the Sign Test.

For the assessment of the Auxiliary Building 542 ft. elevation embedded equipment and floor drain pipe STS data, the sum of the allocated fractions for all embedded equipment and floor drain pipe was 32.671 % of the BIL. Note that the sum of the allocated BIL

SURVEY UNITS 05119A & 05119B fractions for the remaining STS units in the Auxiliary Building STS basement (walls, floors and any remaining penetrations) must be less than or equal to 67.329% as the sum of all allocated fractions in a given STS basement must be less than or equal to one ..

Both survey plans (Sl-05119A-S for the floor drain pipe and Sl-05119B-S for the equipment drain pipe) were designed based upon the acquisition of a measurement for each foot of pipe that was accessible. This resulted in an areal survey coverage of 100%

for the interior surfaces of all accessible pipe. The contribution to the source term inventory from portions of the pipe that were found to be not accessible were extrapolated based on the measured mean concentrations of each ROC from the accessible pipe that was surveyed. Two thousand seven hundred and eighteen (2,718) feet of embedded equipment and floor drain pipe were surveyed in 31 different pipe lengths. Nine hundred and thirty-six (936) feet of pipe was found to be not accessible, either by obstruction or due to insufficient pipe diameter size necessary for the insertion of an available detector. Of the 936 feet of inaccessible pipe, 553 feet had a pipe diameter of 2-inch or less.

The STS results produced a Mean Inventory that was 29.3% of the Auxiliary Building Basement BIL corresponding to an assigned dose of7.324 mrem/yr.

2. SURVEY UNIT DESCRIPTION The Auxiliary Building 542 ft. elevation embedded equipment and floor drain survey unit consists of 31 different pipes ranging from 2-inch to 6-inch in diameter. The floor drain system consists of approximately 2,941 linear feet of floor drain pipe, embedded 4 feet deep in the concrete floor in 28 pipe headers that are accessed by 125 drain openings and terminate in one of the two Auxiliary Building sumps. Sump A services 10 pipe headers in the west portion of the basement and Sump B services 18 pipes in the east portion of the basement. The equipment drain system consists of approximately 713 linear feet of floor drain pipe, embedded 2 inches deep in the concrete floor in 3 pipe headers that are accessed by 4 7 drain openings and terminate in one of two Auxiliary Building equipment drain collection tanks located beneath the 542 ft. elevation floor. The floor and equipment drain headers are presented in Table 1. A layout of the floor and equipment drains is provided in Figures 1 and 2, respectively.

3. CLASSIFICATION BASIS Survey unit 05119 was classified in accordance with ZionSolutions procedure ZS-LT-300-001-002, "Survey Unit Classification."

Throughout the operation of the Zion Nuclear Power Station, and during the period of SAFSTOR, the Auxiliary Building 542 ft. elevation embedded equipment and floor drain system received contaminated liquids from equipment operation, spills and flooding.

During the operation of the facility, storage tank overflow into the Auxiliary Building basement resulted in water flooding up to 2 feet deep. The Historical Site Assessment (HSA) documents 5 occurrences between 1990 and 1996 where the Lake Discharge Tanks overflowed to the Auxiliary Building 542 ft. elevation floor.

No characterization surveys were performed of the interior of the pipe headers, however, operational surveys showed significant dose rates at the drain scuppers. The results of these surveys, the known introduction of contaminated liquids into the pipe, the analysis of contaminated liquids in the sumps and collection tanks prior to processing and the documented spills and flooding in the Auxiliary Building basement would indicate the presence of a significant radioactive source inventory in the pipe. Consequently, all embedded floor and equipment drain pipe in the Auxiliary Building 542 ft. elevation floor was classified as STS Class 1.

4. SURVEY DESIGN Survey design for this STS were incorporated into and performed in accordance with STS Sample Plans Sl-05119A-S and Sl-0511B-S, which were developed in accordance with ZionSolutions procedure ZS-LT-300-001-001, "Final Radiation Survey Package Development."

4.1 DATA QUALITY OBJECTIVES Final Radiation Survey planning and design hinges on coherence with the Data Quality Objective (DQO) process to ensure, through compliance with explicitly defined inputs and boundaries, that the primary objective of the survey is satisfied. The DQO process is described in the LTP in accordance with MARSSIM. The main features of the DQO process for STS survey units 05119A and 05119B are illustrated below.

4.1.1 STATE THE PROBLEM

. The Problem: To demonstrate that the residual radioactivity inventory quantified in STS survey units 05119A and 05119B, when added to the

total allowable residual radioactivity inventory for the Auxiliary Building (a Class 1 STS unit), is below a source term inventory commensurate with the dose criterion in 10 CFR 20.1402 (i.e., the BIL).

Stakeholders: The primary stakeholders are ZionSolutions LLC, Exelon Nuclear Generation, LLC (Exelon), the Illinois Environmental Management Agency (!EMA), and the United States Nuclear Regulatory Commission (NRC).

The Planning Team: The planning team consisted of the assigned Characterization/License Termination (C/LT) Engineer with input from other C/LT personnel as well as the Safety Department. The primary decision maker was the Technical Lead/Radiological Engineer with input from the C/LT Manager.

Schedule: A total of ten (10) working days were assigned to mobilize, implement, and assess the STS in parallel with decontamination and inspection activities.

Resources: The primary resources required were the C/LT Technicians to collect survey measurements and collect media samples, the C/L T Engineer to prepare the plan and evaluate data, the C/LT Field Supervisor to coordinate and monitor field activities, the Survey Mapping/CAD Specialist to prepare .survey maps, Environmental Health and Safety to support work space evaluation hazard assessment and mitigation plans,

• 1abor support for equipment transport and set up and the preparation of survey locations and the Chemistry/Analysis laboratory staff to analyze samples as necessary. Material and equipment resources included a pipe inspection device with indexing and video capabilities (See Snake),

radiation detection instrumentation and sample containers and sample collection equipment.

4.1.2 IDENTIFY THE DECISION The Decision: Determine whether or not the radioactivity inventory remaining in the equipment and floor pipe that is embedded in the concrete floor of the Auxiliary Building 542 ft. elevation basement is less than the allowable source term commensurate with the dose criterion in 10 CFR20.1402, taking into consideration that the SOF for the allowable fraction and mean fraction in the entire STS unit for the Auxiliary Building basement (including concrete walls, concrete floor and other embedded penetrations) must be less than or equal to one. If

SURVEY UNITS 05119A & 05119B measurements indicate that the inventory exceeds the allowable radioactivity inventory, then confirmatory surveys, investigations and/or additional remedia.tion will be performed. If measurements indicate that the inventory does not exceed the allowable radioactivity inventory, then the survey unit meets the release criteria and STS activities are complete.

4.1.3 IDENTIFY THE INPUTS TO THE DECISION Radionuclides of Concern: The primary gamma emitting ROC for the STS of the Auxiliary Building basement STS unit are Co-60, Cs-134 and Cs-137. Ni-63 and Sr-90 are also ROC for the Auxiliary Building basement STS unit. Ni-63 is inferred from the measured concentration of Co-60 and Sr-90 is inferred from the measured concentration of Cs-137. The mixtures used to derive the ratios for inferring Hard-to-Detect (HTD)

ROC was based on the analysis of sediment samples taken from the Auxiliary Building drain pipe. LTP Chapter 6, section 6.5.2 discusses the process used to derive the final suite of dose significant ROC for the decommissioning of ZNPS, including the elimination of insignificant dose contributors from the ROC.

Basement Dose Factors: Building-specific BDF are the product of the Groundwater BDF and Drilling Spoils BDF from ZionSolutions Technical Support Document (TSD)14-010, "RESRAD Dose Modeling for Basement Fill Model, Soil DCGL and Calculation of Basement Fill Model Dose Factors", Rev 2. BDF are caljculated in units of mrem/yr per mCi.

The radioactivity inventory based upon the mean concentration for each ROC is multiplied by the BDF for each radionuclide to calculate the attributed dose from the radioactivity inventory in each pipe. The BDF for the Auxiliary Building basement STS unit from TSD 14-010 are reproduced below.

SURVEY UNITS 05119A & 05119B Basement Inventory Limit: The BDF for the Auxiliary Building STS unit were used to calculate a hypothetical maximum inventory limits for each ROC in the embedded pipe that would equate to 25 mrem/yr. These calculated values are designated as Basement Inventory Limits (BIL). The BIL is used during STS survey design to determine a reasonable areal coverage based upon the theoretical potential of exceeding the inventory limit. The BIL for the Auxiliary Building basement STS unit are reproduced below.

This value was then adjusted by multiplying the BIL by an assigned allocated fraction, which equates to the upper bound of the gray region for the Sign Test. The STS measurement results, which are also converted to units of pCi/m2 , are then divided by the adjusted BIL to derive a SOF value for each measurement.

Areal Coverage Requirements: In accordance with LTP Chapter 5, section 5.5.2.1, 100% areal coverage is required for all Class 1 STS units.

For the STS of the equipment and floor drain pipe embedded in the Auxiliary Building 542 ft. elevation concrete floor, 1" x 1" cesium iodide (CsI) detectors were inserted into each pipe using a simple "push-pull" methodology, whereby the position of the detector inside the pipe can be

• easily determined and in a reproducible manner. The CsI detectors were configured in a fixed geometry relative to the surveyed surface, thus creating a situation where a defensible efficiency can be calculated. The detectors were then deployed into the actual pipe and a timed one-minute

Based upon a conservative "area of detection" for the detectors. used, a measurement interval of one measurement for each foot of pipe conservatively provided 100% areal coverage of the pipe interior surfaces.

Quality Control (QC) Measurements: In compliance with ZS-LT-01, "Quality Assurance Project Plan," replicate measurements were performed on 5% of the survey locations chosen at random.

Investigation Levels: There were no investigation levels directly applicable to individual measurements taken for the STS of the Auxiliary Building 542 ft. embedded equipment and floor drain pipe. However, at the discretion of the C/LT Engineer, additional investigation surveys were an option if anomalies were identified with the data.

Sampling and Analysis Methods to Meet the Data Requirements: A composited sediment samples were acquired during the vacuuming of floor drains_ representative of the following pipe sections;

• West Central Floor Drains

• HUT Floor Drains

• Unit 2 Horizontal Pipe Chase

• Unit I side Floor Drains

• Unit 2 side Floor Drains The sediment samples were taken from the vacuum, which was then decontaminated prior to use in another region. The objectives for the acquisition and analysis of these samples were to assess the radionuclide mixture present in each section and to analyze for the presence of HTD radionuclides. These samples were analyzed initially by the on-site gamma spectroscopy system and then composited and sent for HTD analysis by Eberline Laboratories.

4.1.4 DEFINE THE BOUNDARIES OF THE SURVEY Boundaries of the Survey: See Section 2 of this Release Record.

Temporal Boundaries: Measurements were acquired indoors minimizing seasonal constraints due to weather. The physical configuration of the Auxiliary Building 542 ft. embedded equipment aQ.d floor drain piping

Mtiw'QJ~Ocr'OS"J SURVEY UNITS 05119A & 05119B required a* coordinated effort by multiple groups in order to accomplish personnel and material access for survey performance.

Constraints: The STS of the interior surfaces of the Auxiliary Building 542 ft. embedded equipment and floor drain piping required the pipe to be dry and relatively clear of debris to the extent practicable. There were instances where measurements were acquired with loose sediment and standing water present on the bottom of the pipe, however not to the extent where the detector was submerged or covered.

4.1.5 DEVELOP A DECISION RULE Decision Rule: As the Auxiliary Building 542 ft. embedded equipment and floor drain piping is one of multiple survey units in the Auxiliary Building basement STS unit (e.g. one for the walls, one for the floor and one for any other embedded piping and/or penetrations that may remain in the end-state), the BIL, converted to units of pCi/m2 was adjusted by multiplying the BIL by the allocated fraction assigned to the pipe. The upper bound of the gray region for the Sign Test is the allocated fraction of the BIL for each of the multiple survey units in the Auxiliary Building basement STS unit, as opposed to the full BIL in the case of a basement that has only one STS survey unit. The STS measurement results for each ROC, also in units of pCi/m2 , were divided by the adjusted BIL for each ROC to derive a SOF value for each ROC, which were then summed to derive a total SOF for the measurement.

The Sign Test was used to evaluate the measured radioactivity inventory in each section of pipe against the allocated BIL fraction. The total SOF for each measurement was used as the weighted sum for the Sign Test.

During the assessment of the data, if the survey unit failed the Sign Test, then the allocated fraction was increased until the Sign Test was passed.

This is allowable as long as the allocated fractions in the other STS units in the basement are decreased accordingly such that the revised allocated

• fractions still sum to less than or equal to one. Passing the Sign Test demonstrates that the mean activity of the survey unit is less than the adjusted BIL at a 5% Type I error rate. The Sign Test must be passed for all other survey units in the Auxiliary Building basement STS unit at the final allocated fraction selected. After all survey units in the Auxiliary Building basement STS unit have passed the Sign Test and, the sum of the

[11]

. M~~

SURVEY UNITS 05119A & 05119B allocated fractions is less than or equal to one, then the Mean Inventory Fractions for each of the survey units will also be summed.

If a combination of allocated fractions cannot be_selected that results in all survey units in a given basement passing the Sign Test, or ifthe sum of the Mean Inventory Fractions of all STS units in a basement exceeds one, then the survey unit will fail STS. If a survey unit fails STS, then additional remediation will be performed and the STS performed again. Also, if the_

results of a quality control sample (e.g., splits or replicates) failed the acceptance criteria, then an investigation would be performed and documented.

4.1.6 SPECIFY TOLERABLE LIMITS ON DECISION ERRORS

\

The DQO process incorporates hypothesis testing and probabilistic sampling distributions to control decision errors during data analysis.

Hypothesis testing is an inference tool that compares a baseline condition, referred to as the null hypothesis, to an alternate condition. Hypothesis testing rests on the premise that the null hypothesis is true and that sufficient evidence must be provided to reject it in favor of an alternate hypothesis.

The Null Hypothesis: Residual radioactivity in the survey unit exceeds the release criterion.

Rejection of the null hypothesis in favor of an alternate condition, based on data that reveals the release criterion was not exceeded, would satisfy the release criterion objective of the STS.

Type I Error: This is also known as the "a" error. This is the error associated with incorrectly concluding the null hypothesis has been rejected. In accordance with LTP section 5.5.4, the a error was set at 0.05 (5%).

Type II Error: This is also known as the "W' error. This is the error associated with incorrectly concluding the null hypothesis has been accepted. As the classification for the STS unit for the Auxiliary Building 542 ft. embedded equipment and floor drain piping is Class 1, and the number of measurements to be taken were based on a survey frequency of one measurement for every foot of pipe that was accessible, the Type II error is not applicable for this survey.

SURVEY UNITS 05119A & 05119B

• Lower Bound of the Gray Region: As the classification for the STS unit for the Auxiliary Building 542 ft. embedded equipment and floor drain piping is Class 1, and the number of measurements to be taken were based on a survey frequency of one measurement for every foot of pipe that was accessible, the Lower Bound of the Gray Region is not applicable for this survey.

Upper Bound of the Gray Region: In accordance with LTP section 5.5.4, the Upper Bound of the Gray Region for the Sign Test was the allocated fraction of the BIL for the Auxiliary Building 542 ft. embedded equipment and floor drain piping.

4.1.7 OPTIMIZE DESIGN Type of Statistical Test: The Sign Test was the non-parametric statistical test selected for this STS unit.

Number of Samples: The Auxiliary Building 542 ft. embedded equipment and 'floor drain piping is a Class 1 STS unit. In accordance with L TP Chapter 5, section 5.5.2.1, 100% areal coverage is required for all Class 1 STS units. Based upon a conservative "area of detection" for the detectors used, a measurement interval of one measurement for each foot of pipe conservatively provided 100% areal coverall of all accessible pipe interior surfaces.

The Csl detectors were inserted into each pipe using a simple "push-pull" methodology, whereby the position of the detector inside the pipe was easily determined in a reproducible manner through the use of tape measures and/or distance encoders. This ensured that a timed one-minute measurement was acquired for every foot of pipe travelled.

Number of Judgmental Samples and Locations: Due to the fact that 100%

areal coverage was required for the accessible internal area of all pipe surveyed, the acquisition of judgmental samples was not applicable.

Number of Scan Areas and Locations: For the survey of pipe internal surfaces, areal coverage is achieved by the "area of detection" for each static measurement taken. Scanning, in the traditional context, is not applicable to the survey of pipe internal surfaces.

Number ofSamples for Quality Control: One hundred and thirty-two (132) replicate static measurements were collected to satisfy the 5% requirement

5. SURVEY IMPLEMENTATION Survey instructions for this STS were incorporated into and performed in accordance with STS Sample Plans Sl-05119A-S and Sl-0511B-S, which were developed in accordance with ZionSolutions procedure ZS-LT-300-001-001, "Final Radiation Survey Package Development". The STS unit was inspected and controlled in accordance with ZionSolutions procedure ZS-LT-300-001-003, "Isolation and Control for Final Radiation Survey".

Surveys of the Auxiliary Building 542 ft. embedded equipment and floor drain piping began on May 20, 2016 and concluded on June 27, 2016. The survey design estimated 10 working days to implement the STS in parallel with any required decontamination and inspection activities. In reality, 27 working days were necessary to complete this work due to obstacles and standing water observed in the pipe and the additional time that was necessary to remove debris using a HEPA-vacuum system. Although the work was usually performed during normal working hours, some overtime and weekend work was required. Throughout these activities, briefings were conducted on a daily basis to discuss the expectations for job performance and to review safety aspects of the job.

Prior to inserting radiological detectors into the pipe, video recordings were made of each pipe length using a See Snake miniature camera system. The interior length of each accessible length of embedded pipe was inspected. The miniature camera with

SURVEY UNITS 05119A & 05119B supporting lighting components were maneuvered through the pipe by the manipulation of semi-rigid camera cable, which were manually pushed or pulled to provide locomotion. This inspection provided an unambiguous record of the physical condition of the piping and identified obstructions.

Following inspection, an attempt was made to remove as much standing water and debris from the pipe interior as possible using a HEPA-vacuum system. The vacuuming process also attempted to remove obstacles observed during the inspection that would prevent the passage of the detector during the survey.

Once vacuuming was completed in a section of pipe to the extent practicable, the residual radioactivity remaining in each accessible section of embedded piping was assessed and quantified by direct survey. The approach used for the radiological survey of the interior surfaces of the Auxiliary Building 542 ft. embedded equipment and floor drain piping involved the insertion of a 1" x 1" Csl detector that was attached to the See Snake and transported through the pipe to the maximul!l deployment length, or to a location of drain drop. A simple "push-pull" methodology was used, whereby the position of the detector in the piping system could be easily determined in a reproducible manner. Footage was tabulated on the See Snake, then measurements were obtained at each one-foot location while backing out of the pipe section.

The Csl detectors were configured in a fixed geometry relative to the surveyed surface, thus creating a situation where a defensible efficiency could be calculated. The detectors were then deployed into the actual pipe and timed measurements were acquired at an interval of one measurement for every foot of pipe. A conservative "area of detection" of one-foot was assumed. It was also conservatively assumed that any activity inside of the pipe was uniformly distributed in the area of detection ..

For each detector in each diameter of pipe, an instrument efficiency factor was derived by placing a flexible Cs-137 radiological plane source into either a 4-inch diameter or a 6-inch diameter pipe jig, depending on the diameter of the pipe length to be surveyed. This created a geometry similar to what would be encountered in the actual pipe. Using the known source activity, an efficiency factor was then derived for the detector in that geometry.

A background value was also determined for the detector/instrument combination to be used prior to deployment. The background value was obtained at the location where the pre-use response check of the instrument was performed. The background value was primarily used to ensure that the detector had not become cross-contaminated by any previous use.

Mc..miScUo'llCo"P""J' SURVEY UNITS 05119A & 05119B Daily prior to use and daily following use, each detector was subjected to an Operational Response Check in accordance with procedure ZS-LT-300-001-006, "Radiation Surveys of Pipe Interiors Using Sodium/Cesium Iodide Detectors." The Daily Operational Response Check compared the background response and the response to check sources ranges established for normal background and detector source response to ensure that the detector was working properly.

Once the detector was determined to be fully functional, it was then deployed to the field for insertion into the targeted piping. A one-minute static measurement was acquired at each foot traversed into the pipe. The detector output represented the gamma activity for each one-minute timed measurement in units of gross cpm. The gamma measurement value in units of cpm was then converted to units of dpm using the efficiency factor for the detector applicable to the diameter of the pipe surveyed.

Each measurement assumed a conservative "area of detection" for the CsI detector of one foot. This assumption is_ conservative because there is additional instrument response from contamination located in the pipe at distances outside of the "area of detection".

Consequently, the total activity from the measurement, in units of dpm is adjusted for the total effective surface area commensurate with the pipe diameter and the assumed "area of detection", resulting in measurement results in units of dpm/100 cm2

• Using the appropriate conversion factors, the result is then converted to units of pCi/m2

• This measurement result represents a commensurate and conservative gamma surface activity for the one foot of pipe surface where the measurement was taken.

Two thousand seven hundred and eighteen (2, 718) feet of embedded equipment and floor drain pipe were surveyed in 31 different pipe lengths. Nine hundred and thirty-six (936) feet of pipe was found to be not accessible, either by obstruction or due to insufficient pipe diameter size necessary for the insertion of an available detector. Of the 936 feet of inaccessible pipe, 553 feet had a pipe diameter of 2-inch or less.

After completion of the STS measurements in the pipe, the sample plan was reviewed for completeness and the survey data was validated in accordance with procedure ZS-LT-300-001-004, "Final Radiation Survey Data Assessment." Data processing includes converting measurement data into reporting units, validating instrument applicability and sensitivity, calculating relevant statistical quantities, and verification that all DQO have been met. In accordance with step 5 .4 of the procedure, a preliminary Data As,sessment was prepared for each section of pipe surveyed.

Sediment samples were acquired during the vacuuming of floor drains representative of the following pipe sections;

A unique radionuclide mixture was determined for each of the 5 regions based on the analysis of the sediment samples by the on-site gamma spectroscopy system. The primary gamma emitting ROC for the STS of the Auxiliary Building basement STS unit are Co-60, Cs-134 and Cs-137.

Ni-63 and Sr-90 are also ROC for the Auxiliary Building basement STS unit. Ni-63 is inferred from the measured concentration of Co-60 and Sr-90 is inferred from the measured concentration of Cs-137. The ratios used to infer the Ni-63 and Sr-90 concentration were based on the analysis of sediment samples taken from the Auxiliary Building drain pipe shown in Table 10.

SURVEY UNITS 05119A & 05119B LTP Chapter 6, section 6.5.2 discusses the process used to derive the final suite of dose significant ROC for the decommissioning of ZNPS, including the elimination of insignificant dose contributors from the ROC. In addition, ZSRP committed to identify and calculate the dose from insignificant contributor radionuclides in several areas where characterization had not yet occurred. The Auxiliary Building 542 ft elevation embedded equipment and floor drain pipe were identified as an area where this assessment was to be performed. If the insignificant contributor dose from the HTD analysis results is less than the insignificant contributor dose from LTP Chapter 6, section 6.5.2, then the current adjustment to the BDF to account for insignificant contributor dose would be retained. If the insignificant contributor dose from the HTD analysis results was greater than the insignificant contributor dose from L TP Chapter 6, section 6.5.2, then the BDF for the Auxiliary Building 542 ft. elevation embedded equipment and floor drain pipe would be re-adjusted to account for the increased dose.

Using the same approach as described in LTP Chapter 6, section 6.5.2, the mixture percentages for the initial suite of radionuclides for ZSRP were derived using the results from the analysis of the composited sediment sample taken from the Auxiliary Building 542 ft. elevation embedded equipment and floor drain pipe (Table l 0). Several radionuclides in the initial suite were not positively identified in the sediment sample analyses. The mixture percentages for these radionuclides were conservatively determined using the reported MDC values. Note that Np-237 was removed from the list of the initial suite for ZNPS and is not included in this analyses. The mixture percentages for the initial suite of radionuclides for ZSRP, as well as the percent of annual dose are provided in the following table.

SURVEY UNITS 05119A & 05119B The sum of the dose contribution from insignificant radionuclides, including H-3, Eu-152 and Eu-154 equals 2.368%. For the Auxiliary Building basement, a margin of 100%

(factor of two) was added to the insignificant contributor dose percentage. The revised insignificant fraction, after applying a multiplier factor of two, is 2.640%. Consequently, no re-adjustment of the Auxiliary Building BDF is necessary for application to the embedded pipe.

The Auxiliary Building BIL is a hypothetical maximum inventory level for each ROC that would equate to 25 mrem/yr. The BIL for each ROC was converted to units of pCi/m2 by converting mCi to pCi and then dividing by the internal surface area of the pipe being surveyed. This value was then adjusted by multiplying the BIL by an allocated fraction for the pipe being surveyed. This "Adjusted BIL per STS Area,"

equates to the Upper Bound of the Gray Region for the Sign Test.

Each gross gamma measurement was multiplied by the appropriate ratio for each ROC, based on the mixture applicable to the pipe undergoing survey, to derive an "Activity per ROC" for each ROC in units of pCi/m2

• This value was then divided by the "Adjusted BIL per STS Area" to derive a "Fraction of the Allowable Inventory" for each ROC.

These individual ROC fractions were then summed to produce a SOF for the measurement. The SOFs for each measurement were then used as the Weighted Sum (Ws) variable for the Sign Test. The Sign Test was then used to evaluate the remaining

• residual radioactivity in each pipe against the allocated fraction of the allowable inventory for the pipe.

During the assessment of the data, if the pipe failed the Sign Test, then the allocated fraction of the allowable inventory assigned to the pipe was increased until the Sign Test was passed. This is acceptable as long as the allocated fractions in the other STS units in the basement are decreased accordingly such that the revised allocated fractions for all STS survey units in the Auxiliary Building basement still sum to less than or equal to one.

Once the Sign Test was passed, a "Mean Activity per ROC" was derived in units of pCi/m2

• This value represented the mean concentration for all measured or derived individual measurement concentrations for each ROC. The mean concentration for each ROC was then multiplied times the total internal surface area of the surveyed pipe and converted to units of mCi to produce the "Total Mean Activity" for each ROC. The Total Mean Activity for each ROC was then divided by the BIL for each ROC to derive a "Mean Fraction of Allowable Inventory" for each ROC, which were then summed to produce a "Mean Inventory Fraction" for the pipe surveyed. In addition, the Total Mean Activity for each ROC, in units of mCi, was also multiplied by the Auxiliary Building BDF for each ROC (in units of mrem/yr per mCi) to calculate a mean dose for each ROC

SURVEY UNITS 05119A & 05119B in units ofmrem/yr. The mean dose for each of the ROC were then summed to calculate a total "Mean Dose" assigned to the pipe surveyed.

Two thousand seven hundred and eighteen (2, 718) feet of embedded equipment and floor drain pipe were surveyed in 31 different pipe lengths. This equated to 2, 718 separate STS measurements. The length of pipe surveyed, number of measurements taken and area of pipe surveyed in presented in Table 12. The "FRS Field Log" (ZS-LT-300-001-001, Attachment 14) was used to document field activities and other information pertaining to each STS performe_d.

During the inspection and survey of several pipe sections, obstructions were identified due to the presence of debris and/or configuration that prevented the insertion and/or transport of the CsI detector in the pipe. Nine hundred and thirty-six (936) feet of pipe was found to be not accessible. Of the 936 fee~ of inaccessible pipe, 553 feet were the small bore equipment drain pipe which has a pipe diameter of 2-inch. The diameter of this pipe was of insufficient size to insert the available 1" x 1" CsI detectors. Only 383 feet of pipe with a diameter sufficient for survey was obstructed due to the presence of debris. The identified obstructed pipe, including the estimated lengths and area of obstructed pipe surface are also presented in Table 12.

The contribution to the source term inventory from portions of the pipe that were found to be not accessible were extrapolated based on the measured mean concentrations of each ROC from the accessible pipe that was surveyed. The "Mean Activity per ROC" in units of pCi/m2 that was determined for the length of pipe that was surveyed was multiplied times the sum of the area of the surveyed pipe plus the area of un-surveyed pipe and then converted to units of mCi. The same process was again then used to derive a "Mean Fraction of Allowable Inventory" for each ROC, the "Mean Inventory Fraction" for the pipe and the assigned dose, however all results are denoted as "adjusted" to include the source term contribution from the area of the un-surveyed pipe, assuming that the pipe is uniformly contaminated at the "Mean Activity per ROC derived for the pipe surveyed.

7. QUALITY CONTROL In compliance with ZS-LT-01, "Quality Assurance Project Plan," replicate measurements were performed on 5% of the survey locations chosen at random. One hundred thirty-two (132) replicate measurements were taken. Using the acceptance criteria specified in NRC Inspection Procedure No. 84750, "Radioactive Waste Treatment, and Effluent and Environmental Monitoring," there was acceptable agreement between all replicate measurements. Refer to Attachment 3 for quality control analysis results.

8. INVESTIGATIONS AND RESULTS As 100% areal coverage of all accessible pipe interior surface area was achieved by the STS, no investigations were required or performed.

9. REMEDIATION AND RESULTS Prior to acquiring STS measurements, the accessible lengths of the embedded pipe were vacuumed to remove gross amounts of debris and water inside the pipe to allow detector access. No radiological remediation was performed in this survey unit as a result of the STS.

10. . CHANGES FROM THE SURVEY PLAN There were no changes made and no addendums added to STS Sample Plans Sl-05119A-S and Sl-0511B-S.

11. DATA QUALITY ASSESSMENT (DQA)

In accordance with section 5.2 of procedure ZS-LT-300-001-004, the DQOs, sample design, and data were reviewed for completeness, accuracy, and consistency.

Documentation was complete and legible. The STS unit was properly classified as Class

1. All measurement results were individually reviewed and validated. The number of measurements were sufficient to meet the requirement of 100% areal coverage of accessible surfaces. The instrumentation used to perform the STS were in calibration, capable of detecting the activity with an adequate MDC and successfully response checked prior to and following use. An adequate number of replicate measurements were taken and the results meet the acceptance criteria as specified in the QAPP.

The Sign Test was performed on each set of data representing each length of pipe surveyed. The SOF for each measurement, calculated using the fraction of the allowable inventory assigned to the pipe, was used as the weighted sum variable for the test. Each pipe passed the Sign Test at the assigned allocated fraction of inventory. The total fraction of the Auxiliary Building Basement BIL assigned to the Auxiliary Building 542

SURVEY UNITS 05119A & 05119B ft. elevation embedded equipment and floor drain pipe was32.671 %. Taking into consideration that the allocated fraction of the BIL available for the remaining STS units in the Auxiliary Building basement (concrete walls, concrete floor and any other remaining embedded pipe and/or penetration) is deemed sufficient at 67 .329%, the 32.671 % value assigned to embedded pipe was acceptable. Therefore, the STS unit passes and meets the release criteria.

12. ANOMALIES No anomalies were observed during the performance or analyses of the survey.

13. CONCLUSION In situations where there are multiple survey units in a STS basement (e.g. the Auxiliary Building has at least three STS units, one for the walls, one for the floor and one for embedded piping and/or penetrations), a fraction of the BIL will be allocated to each survey unit that is selected apriori to the performance of STS for planning purposes. The sum of the allocated BIL fractions for each survey unit applicable to a given basement must be less than or equal to one.

If the actual mean inventory in a STS unit exceeds the allocated fraction, or the survey unit fails the Sign Test, then the allocated fraction may be increased as long as the allocated fractions in the other STS units in the basement are decreased accordingly such that the revised allocated fractions still sum to less than or equal to one. After all survey units are demonstrated to pass the Sign Test, the Mean Inventory Fractions for each of the survey units are summed.

If a combination of allocated fractions cannot be selected that results in all survey units in a given basement passing the Sign Test, or if the sum of the Mean Inventory Fractions of all STS units in a basement exceeds one, then the survey unit will fail STS. If a survey unit fails STS, then additional remediation will be performed and the STS performed again.

For the assessment of the Auxiliary Building 542 ft. elevation embedded equipment and floor drain pipe STS data, the sum of the allocated fraction of the BIL for all embedded equipment and drain pipe was 32.671 %. Note that the sum of the allocated BIL fractions for the remaining STS survey units in the Auxiliary Building STS basement (walls, floors and any remaining penetrations) must be less than or equal to 67.329% as the sum of all allocated fractions in a STS basement must be less than or equal to one. The STS results produced a Mean Inventory Fraction of0.293 and an assigned dose of7.324 mrem/yr.
