SUMMARY

This Final Status Survey (FSS) Release Record for survey unit 01112, Unit 1 Containment Building Penetrations, has been generated for the Zion Station Restoration Project (ZSRP) in accordance with ZionSolutions procedure ZS-LT-300-001-005, Final Status Survey Data Reporting (Reference 1) and satisfies the requirements of Section 5.11 of the Zion Station Restoration Project License Termination Plan (LTP)

(Reference 2).

Three (3) FSS sample plans (S1-01112A-F #1, S1-01112A-F #2, S1-01112A-F #3) were developed to perform this work in accordance with ZionSolutions procedure ZS-LT-300-001-001, Final Status Survey Package Development (Reference 3), the ZSRP LTP, and with guidance from NUREG-1575, Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) (Reference 4).

Final Status Survey was performed to demonstrate that the concentrations of residual radioactivity on the interior surfaces of the penetrations were equal to or below site-specific Derived Concentration Guideline Levels (DCGL) corresponding to the dose criterion in 10 CFR 20.1402. Initially, the penetrations were segregated and classified in accordance with the type of system and system use. However, in a conservative measure to ensure that all accessible surfaces within each end-state penetration would be subjected to FSS, the classification of all penetrations was changed to Class 1.

Two (2) different survey approaches were used for FSS depending on the diameter, length and access to the penetrations. FSS measurements acquired under FSS sample plans #1 and #2, which were applicable to penetrations with an internal diameter (ID) less than or equal to 12 inches, consisted of a static gamma measurement taken at 1-foot intervals inside the penetration using a sodium iodide (NaI) detector, conservatively assuming a Field of View (FOV) of 1-foot for each measurement and thus providing 100% areal coverage of the accessible internal surfaces of the penetration.

FSS measurements acquired under FSS sample plan #3, which was applicable to penetrations with an ID greater than 12 inches, consisted of a 100% scan with a hand-held beta-gamma detector of the interior surface area of the penetration and at least one (1) 1-minute static gross beta-gamma measurement at a systematic location based on a triangular grid and a 1-minute static measurement at the location of the highest observed scan result in each penetration..

For the five 24 inch diameter penetrations encompassing the Recirculating Pump suction and Cavity Floor Sump suction pipes, a NaI detector was used (FSS sample plan #2) with recalculated efficiencies for a 24 inch diameter pipe, permitting one-foot interval static

[7]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 measurements along the approximate 50 foot length of each pipe. All five were subsequently grouted. See Figures 2 and 3.

For the FSS of the Unit 1 Containment Building Penetrations, three hundred and sixty-nine (369) measurements were obtained. LTP Chapter 6, section 6.4.5 states, The dose from penetrations is summed with the dose from the wall and floor surfaces of both basements that the penetration interface. The Containment penetrations interfaced with the Auxiliary Building and the Turbine Building (through the East and West Main Steam Valve Houses). Consequently, the FSS design employed the DCGLs for the Containment penetrations, which were the most limiting and, the resultant dose was added to each basement (Unit 1 Containment, Auxiliary Building and Turbine Building) to ensure compliance with the LTP.

The mean Sum of Fractions (SOF) using the Operational DCGL (OpDCGLPN) for Containment penetrations was 0.564. Forty-three (43) measurements exceeded the OpDCGLPN but were less than the BcDCGLPN for Containment penetrations. The maximum Operational SOF (OpSOF) for a single measurement using OpDCGLPN for Unit 1 penetrations was 8.600 with a corresponding Base Case SOF (BcSOF) using BcDCGLPN of 0.585. All the penetrations that exceeded an OpSOF of one interfaced with the Auxiliary Building. The FSS results produced a mean BcSOF, compared against the BcDCGLPN for the Unit 1 Containment Building Penetrations of 0.038. Using Equation 5-6 from LTP Chapter 5, section 5.5.5, the mean BcSOF for the Unit 1 Containment Building Penetrations was adjusted by a value of 0.020 to account for the identified elevated measurements (measurements greater than the OpDCGLPN but less than the BcDCGLPN). The adjusted mean BcSOF for the Unit 1 Containment Penetrations was 0.059 and the dose assigned to the survey unit was 1.468 mrem/yr.

Penetration No. 049, Fuel Transfer Tube, was completely removed and shipped off site as waste. It was a 24-inch penetration that was completely removed leaving an access opening of approximately eight by eight feet square that facilitated personnel and ISOCS access for the Spent Fuel Pool. In accordance with LTP Chapter 5 section 5.5.5, twenty seven (27) of the penetrations required grouting. However, twenty two (22) of 27 penetrations that exceeded the criteria were physically removed and disposed of as waste during building demolition. Only the remaining five (5) Unit 1 Containment Building Penetrations were actually grouted. No dose reduction was attributed to the survey unit because of grouting.

2. SURVEY UNIT DESCRIPTION In accordance with the definition of penetrations specified in LTP Chapter 5, Section 5.5.5, The end state will include embedded piping and penetrations. An embedded pipe is defined as a pipe that runs vertically through a concrete wall or horizontally through a concrete floor and is contained within a given building. A penetration is defined as a pipe (or remaining pipe sleeve, if the pipe is removed, or concrete, if the pipe and pipe sleeve is removed) that runs through a concrete wall and/or floor, between two buildings, and is open at the wall or floor surface of each building. A penetration could also be a pipe that runs through a concrete wall and/or floor and opens to a building on one end and the outside ground on the other end.

The Unit 1 Containment Building Penetrations survey unit consisted of sixty-one (61) penetrations ranging from six (6) inches to fifty (50) inches in diameter. A description of the original End State lengths and surface areas for the Unit 1 Containment Building Penetrations are depicted in ZionSolutions Technical Support Document (TSD)14-016, Description of Embedded Piping, Penetrations, and Buried Pipe to Remain in Zion End State (Reference 5) and is summerized in Table 1 below.

Eight (8) penetrations listed for Unit 1 Containment in TSD 14-016 are above the basement End State 588 foot elevation and were not included as part of the FSS. Five (5) penetrations residing in the Recirculating Water Sump and Cavity Flood Sump had an original End State of pipe in sleeve. The piping within the penetrations was removed during decommissioning, leaving only a larger diameter open sleeve for each of the five penetrations. Additionally, a section of wall housing one (1) penetration (the Fuel Transfer Tube) was demolished to allow access to the building (See Figure 1).

In accordance with LTP Chapter 5, section 5.5.5, penetration survey units have total surface areas that are less than the area of the wall/floor surface survey unit that the penetrations interface. To eliminate the potential for activity levels in penetrations that could lead to releases greater than the adjacent basement walls and floors, the following remediation and grouting action levels were applied to measurements of surface activity in penetrations.

• If maximum activity exceeded the BcDCGLPN from LTP Chapter 5, Table 5-13 (BcSOF >1), then remediation was performed.

• If the maximum activity in a penetration exceeded the most limiting OpDCGLB from LTP Chapter 5, Table 5-4 of the two basements where a penetrations interface (OpSOF>1), but is below the BcDCGLPN from LTP Chapter 5, Table 5-13, then the penetration was remediated or grouted.

• If a penetration was remediated and the maximum activity continued to exceed the most limiting OpDCGLB from LTP Chapter 5, Table 5-4 of the two basements where a penetrations interface (OpSOF>1), but was less than the OpDCGLPN (LTP Chapter 5, Table 5-14), then the penetration was grouted.

• If the maximum activity was below the surface OpDCGLB from LTP Chapter 5, Table 5-4, then grouting of the penetration was not required.

All other penetrations interfaced between Unit 1 Containment and the Auxiliary Building.

3. CLASSIFICATION BASIS Survey unit 01112 was classified in accordance with ZionSolutions procedure ZS-LT-300-001-002, Survey Unit Classification (Reference 6).

The Unit 1 Containment Building Penetrations were initially classified as Class 1, Class 2, or Class 3, (see Table 3 above), based on historical assessment, exposure to radioactive materials and system use. As a conservative measure, the classifications of all Unit 1 Containment Building Penetrations were changed to Class 1. Consequently, sufficient measurements were taken in all Unit 1 Containment Building Penetrations to ensure 100% areal coverage of all accessible internal surfaces within the penetrations.

The Unit 1 Containment Building housed the Unit 1 Reactor Vessel, Steam Generators, and Pressurizers. In addition, the Unit 1 Containment also housed numerous systems containing primary coolant as well as radioactively contaminated support systems.

System leakage and maintenance activities over the operating life of the reactor resulted in the radiological contamination of most of the interior surfaces of the structures. Some components, equipment, structural steel and concrete became radioactive due to neutron activation. Based on the building design basis and the operating history, all internal survey units in the Unit 1 Containment Building were given an initial classification of Class 1 in accordance with the Zion Station Historical Site Assessment (HSA)

(Reference 7).

The Unit 1 Containment Penetrations were building to building pipe pathways for various primary and secondary systems. The location of the penetrations, their function, and the operational history of the Unit 1 Containment Building supported the initial classifications. The FSS results for penetrations that connect the Unit 1 Containment and the Auxiliary Building or the Unit 1 Containment and the and Turbine Building are presented as Unit 1 Containment penetrations as the penetration DCGLs for the Unit 1 Containment are limiting (based on the predominant Radionuclides of Concern (ROC) of Cs-137).

From June of 2012 through January of 2013, site characterization was performed in Unit 1 Containment. The results of the site characterization surveys performed from 2010 to 2013 are documented in ZionSolutions TSD 14-028, Radiological Characterization Report (Reference 8) and in Chapter 2 of the LTP. During the time that initial

[16]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 characterization was performed, all radioactive systems and components were still located inside Containment. Consequently, ambient radiation dose rates inside the Containment prohibited the direct assessment of penetrations or system interior surfaces by scanning or direct measurement.

On November 3, 2016, the last routine surveys were conducted in Unit 1 Containment, before heavy demolition started and access was no longer possible. Surveys 2016-2053 and 2016-1988, conducted in the Outer Missile Barrier (OMB) area of Unit 1, showed a maximum contamination level of 20,000 disintegrations per minute (dpm)/100cm2 and that the maximum dose rate was 5.0 mR/hr. Survey 2016-3470, conducted in the Inner Missile Barrier (IMB) area of Unit 1, showed a maximum loose contamination level of 8,000 dpm/100cm2 and a maximum dose rate of 7.0 mR/hr.

A Radiological Engineer (RE) performed the visual inspection and walk-down of the survey unit on February 27, 2018 and all Unit 1 Containment survey units were accepted for turnover by the Characterization/License Termination (C/LT) Group. The purpose of the walk-down was to assess the physical condition of the survey unit, evaluate access points and travel paths and identify potentially hazardous conditions. A final classification assessment was performed in accordance with procedure ZS-LT-300-001-002, Survey Unit Classification as part of the survey design for FSS.

The Unit 1 Containment Building Penetrations were initially classified as Class 1, Class 2, or Class 3, based on historical assessment, exposure to radioactive materials and system use. Based upon completion of the Survey Unit Classification Basis for final classification, which included a review of the historical information, the results of the Characterization Survey data and completion of a final Survey Unit Classification Worksheet, the correct final classification of penetrations within Unit 1 were validated.

As a conservative measure, the classifications of all Unit 1 Containment Building Penetrations were changed to Class 1. Consequently, sufficient measurements were taken in all Unit 1 Containment Building Penetrations to ensure 100% areal coverage of all accessible internal surfaces within the penetrations.

4. DATA QUALITY OBJECTIVES (DQO)

Final Status 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 ZSRP LTP in accordance with MARSSIM. The appropriate design for a given survey was developed using the DQO process as outlined in Appendix D of MARSSIM.

[17]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 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 would satisfy the primary objective of the FSS sample plan.

The primary objective of the FSS sample plan is to demonstrate that the level of residual radioactivity in the penetrations that comprised survey unit 01112 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).

ZionSolutions TSD 11-001, Technical Supoort Document for Potential Radionuclides of Concern During the Decommissioning of the Zion Station (Reference 9) established the basis for an initial suite of potential ROC for the decommissioning of the Zion Nuclear Power Station (ZNPS). LTP Chapter 6, section 6.5.2 discusses the process used to derive the ROC for the decommissioning of ZNPS, including the elimination of insignificant dose contributors (IC) from the initial suite. Table 4 presents the ROC for the Containment Basement structural surfaces and the normalized fractions based on the radionuclide mixture.

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 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 penetrations.

The End State Basements are comprised of steel and/or concrete structures which will be covered by at least three feet of clean soil and physically altered to a condition which would not realistically allow the remaining structures, if excavated, to be occupied. The exposure pathways in the Basement Fill Model (BFM) are associated with residual radioactivity in floors and walls that is released through leaching into water contained in the interstitial spaces of the fill material. The BFM assumes that the inventory of residual radioactivity in a given building is released either instantly or over time by diffusion, depending on whether the activity is surficial or volumetric, respectively. The activity released into the fill water will adsorb onto the clean fill, as a function of the radionuclide-specific distribution coefficients, resulting in equilibrium concentrations between the fill and the water. Consequently, the only potential exposure pathways after backfill, assuming the as-left geometry, are associated with the residual radioactivity in the water contained in the fill.

The final outputs of the BFM are the Penetration DCGLs, in units of pCi/m2, which are calculated using the BFM Groundwater (GW) and BFM Drilling Spoils Dose Factors (LTP Chapter 6, Tables 6-24 and 6-25) using Equation 6-9. The BcDCGLPNs are radionuclide-specific concentrations that represent the 10 CFR 20.1402 dose criterion of 25 mrem/yr and are calculated for each ROC and each backfilled Basement. The unity rule is applied when there is more than one ROC. The measurement results for each singular ROC present in the mixture are compared against their respective DCGL to derive a dose fraction.

The BcDCGLPNs, for the unrestricted release of the Unit 1 Containment Basement penetrations, are provided in Table 5. The IC dose percentage of 10% was used to adjust the Containment Basement BcDCGLPN to account for the dose from the eliminated IC radionuclides.

[19]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 Each radionuclide-specific BcDCGLPN is equivalent to the level of residual radioactivity (above background levels) that could, when considered independently, result in a Total Effective Dose Equivalent (TEDE) of 25 mrem/yr to an Average Member of the Critical Group (AMCG). To ensure that the summation of dose from each source term is 25 mrem/yr or less after all FSS is completed, the BcDCGLPN are reduced based on an expected, or a priori, fraction of the 25 mrem/yr dose limit from each source term. The reduced DCGLPN, or Operational DCGLPN can be related to the BcDCGLPN as an expected fraction of dose based on an a priori assessment of what the expected dose should be based on the results of site characterization, process knowledge and the extent of planned remediation. The OpDCGLPN is then used as the DCGL for the FSS design of the survey unit (calculation of surrogate DCGLs, investigations levels, etc.). Details of the OpDCGLPN derived for each dose component and the basis for the applied a priori dose fractions are provided in ZionSolutions TSD 17-004, Operational Derived Concentration Guideline Levels for Final Status Survey (Reference 10).

Survey instrument response

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 checks were required prior to issuance and after the instrument had been used. Control and accountability of survey instruments was required to assure the quality and prevent the loss of data. The minimum acceptable minimum detectable concentration (MDC) for measurements obtained using field instruments was 50 percent of the applicable Operational DCGL.

5. 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 ZS-LT-300-001-001 Final Status Survey Package Development. The FSS plans for the survey of penetrations employed sample designs that combined hand-held scanning with static measurements and pipe detector survey methodologies.

The survey method for large diameter penetrations (>12) differs from smaller penetrations due to measurement sensitivity (i.e., MDCs) differences in the two size regimes. The larger penetrations were surveyed using a similar approach to traditional building surface surveys whereas the smaller penetrations were surveyed with a single detector advanced through the length in 1-foot increments and centrally positioned.

Sample Plans S1-01112A-F #1 and S1-01112A-F #2 addressed the survey of penetrations smaller than 12 inches in diameter (P001, P003-P004, P019, P023, P042-P043, P050, P054, P056, P064, P081, P086-P089 and P103) and Sample Plan S1-01112A-F #3 addressed the survey of penetrations with a diameter greater than 12 inches (P005-P012, P017-P018, P020-P022, P066-P070, P073-P074, P090-P098, P-104-P105, P112-P113, P115-P118 and P127-P128). As an exception, the five 24-inch diameter penetrations for the Cavity Flood Sump and the Recirculating Sump suctions (P035-P037, P123 and P124) were surveyed using the gamma detector approach as the length of the pipes (~50 feet) prevented access solely by hand-held detectors.

Section 5.1 of LTP Chapter 5 states that H-3, Co-60, Ni-63, Sr-90, Cs-134, Cs-137, Eu-152, and Eu-154 would be the ROC in survey unit 01112. During FSS, concentrations for Hard-to-Detect (HTD) ROC H-3, Ni-63, and Sr-90 are inferred using a surrogate approach. Cs-137 is the principle surrogate radionuclide for H-3 and Sr-90, and Co-60 is the principle surrogate radionuclide for Ni-63. The mean, maximum and 95% Upper Confidence Level (UCL) of the surrogate ratios for concrete core samples taken in the Unit 1 Containment Building basement was calculated in ZionSolutions TSD 14-019, Radionuclides of Concern for Soil and Basement Fill Model Source Terms (Reference 11) and are presented in Table 8 (reproduced from LTP Chapter 5, Table 5-12). The maximum ratios were used in the surrogate calculations during FSS.

The most limiting OpDCGLPN was determined to be Co-60 (8.41E+06 pCi/m2 or 1.87E+05 dpm/100cm2). This was the action level used for hand-held scan and static measurements and pipe detector static measurements in these penetrations. Action levels in counts per minute (cpm) for pipe detector surveys were calculated using the limiting Co-60 OpDCGLPN (1.87E+05 dpm/100cm2), the effective area of detection for the various diameter penetrations, and the limiting efficiency for each size penetration. The action levels in cpm for hand-held surveys were calculated using the limiting Co-60 OpDCGLPN and the efficiency of the instrument/detector combo. Table 9 provides a breakdown of the instrumentation and action levels used for the FSS results of the Unit 1 Containment Building Penetrations.

>Operational DCGL or Class 1 >MDCscan if MDCscan is greater >Operational DCGL than Operational DCGL Two (2) survey methodologies were utilized for the FSS of the Unit 1 Containment Building Penetrations, pipe detector survey or hand-held survey. This was due to the varying diameters and lengths of the penetrations. The survey designs for the FSS of Survey Unit 01112 using the different methodologies are detailed below.

Sample plans #1 and #2 required that measurements be collected with a pipe detector.

Penetrations included in plans #1 and #2 were twelve (12) inches in diameter or smaller, with the exception of the five (5) sump penetrations (23-inch ID) which were designated to be surveyed with a pipe detector because of their length (approximately 50 feet each).

Twenty-two (22) of the sixty-one (61) total penetrations were included in the survey design for pipe detectors. Refer to Table 9 for the FSS instrumentation summary. The total length of the penetrations under the pipe detector methodology is 339.69 feet (103.54 m) with a total interior surface area of 162.22 m2. As a Class 1 survey unit, the survey design required a 100% areal coverage. For the survey of pipe or penetration internal surfaces that cannot be practically surveyed using a hand-held detector methodology, areal coverage is achieved by the area of detection for each static measurement taken. Scanning, in the traditional context, is not applicable to this type of survey. With a 1-foot area of detection, a 1-minute static measurement at 1-foot increments throughout the penetration length was sufficient to provide 100% areal coverage. For 339.69 feet of penetrations in the survey unit, at least 339 measurements were required to satisfy the 100% coverage requirement.

Sample plan #3 required that measurements be collected with a hand-held detector.

Penetrations included in sample plan #3 were larger than twelve (12) inches in diameter.

Thirty-nine (39) of the sixty-one (61) total penetrations were included in the survey design for hand-held detectors. Refer to Table 9 for the FSS instrumentation summary.

The total length of the penetrations under the hand-held methodology is 168.45 feet (51.34 m) with a total interior surface area of 90.87 m2. For the survey of these larger diameter pipes, the survey design required 100% scan of the accessible interior surfaces of the penetration. In addition, a minimum of one 1-minute static measurement was acquired in each penetration at systematic locations based on a triangular grid, and at least one 1-minute static measurement was acquired in each penetration at the location of the highest scan result. The sixteen (16) systematic static measurement locations are

[25]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 denoted in Table 11 below. The locations were developed using Visual Sample Plan (VSP) using a pre-determined number of measurements (16) with a random start point on a triangular grid superimposed on the laid out interior surface area of the relevant penetrations.

The survey design required a total of 388 static measurements [369 measurements and 19 for Quality Control (QC)] for the FSS of the Unit 1 Containment Building Penetrations.

Maps of the penetrations and measurement locations are provided in Attachment 1.

The implementation of quality control measures as referenced by LTP Chapter 5, section 5.9 and ZionSolutions ZS-LT-01, Quality Assurance Project Plan (for Characterization and FSS) (QAPP) (Reference 12) includes the collection of a replicate measurements at 5% of the measurement locations with the QC locations selected at random. One (1) measurement out of every twenty (20) was required for QC compliance.

6. SURVEY IMPLEMENTATION Survey instructions for this FSS were incorporated into and performed in accordance with FSS Sample Plans S1-01112AF #1, #2, and #3, which were developed in accordance with ZionSolutions procedure ZS-LT-300-001-001, Final Status Survey Package Development. The FSS unit was inspected and controlled in accordance with ZionSolutions procedure ZS-LT-300-001-003, Isolation and Control for Final Status Survey (Reference 13).

Surveys of the Unit 1 Containment Building Penetrations began on March 9, 2018 and concluded on April 19, 2018. The survey design estimated six (6) working days to implement the FSS in parallel with any required decontamination and inspection activities. In reality, ten (10) working days were necessary to complete this work.

Throughout these activities, briefings were conducted on a daily basis to discuss the expectations for job performance and to review the safety aspects of the job.

Visual inspections of the penetrations were performed prior to the start of the survey.

Inspections were performed to ensure that the penetrations were relatively dry and free of debris.

For pipe detector surveys using a NaI detector, a background value was 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. Background was not subtracted from any measurement.

Daily, prior to and 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 (Reference 14). The Daily Operational Response Check compared the background response and the response to check source 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.

[27]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 Each measurement assumed a conservative area of detection for the NaI 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.

For the penetration surveys performed with hand-held detectors, a background value was determined for the detector/instrument combination as the average of five (5) ambient 1-minute static measurements. An Alarm Set Point was developed using the background value plus the Action Levels dictated in Table 9.

The entire surface area (100%) of the interior surface area of the designated penetrations were scanned using either the Ludlum 2350-1 paired with a Ludlum 43-68 detector or a Ludlum 2360 paired with a Ludlum 43-93 detector operated in the rate-meter mode and using audio response. The probe was positioned as close to the surface as possible and was moved at a scan speed of 0.25 meters per second.

Systematic 1-minute static measurements were acquired at the locations denoted in Table

11. Additionally, 1-minute static measurements were taken at the location of highest scan result in each penetration. Using the established efficiencies (denoted in Table 9),

the static measurement activities in cpm were converted to activities in dpm/100 cm2 and then to pCi/m2 using the appropriate conversion factors.

7. SURVEY RESULTS After completion of the FSS measurements in the penetrations, the sample plan was reviewed to confirm the completeness of the survey and the survey data was validated in accordance with procedure ZS-LT-300-001-004, Final Status Survey Data Assessment (Reference 15). 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.

For measurements acquired with a NaI detector, the gross output of the measurement is converted to units of dpm by dividing by the efficiency. The effective FOV of the measurement is calculated based upon diameter of the pipe at a length of 1 foot. The result, following unit conversion, is a gross gamma measurement result in units of pCi/m2.

[28]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 For measurements acquired as a direct static measurement with a hand-held detector, the gross gamma output of the measurement is again converted to units of dpm by dividing by the efficiency. As the detector has an area of 100 cm2, the units for the measurement are actually in units of dpm/100cm2. Again, through unit conversion, units of dpm/100cm2 are converted to units of pCi/m2.

Using the mixture from Table 5-2 of LTP Chapter 5 (reproduced as Table 4 of this Release Record), the gross gamma result from each measurement is multiplied by the normalized gamma mixture fractions for C-60, Cs-134 and Cs-137 to derive a radionuclide specific concentration for each gamma ROC. The HTD ROC concentrations for H-3, Ni-63 and Sr-90 were then inferred using the maximum surrogate ratios from LTP Chapter 5, Table 5-15 (reproduced as Table 8 of this Release Record).

Each concentration for each measurement is then compared against the OpDCGL to produce an OpSOF for each ROC, which were then summed to derive an OpSOF for the measurement.

LTP Chapter 6, section 6.4.5 states, The dose from penetrations is summed with the dose from the wall and floor surfaces of both basements that the penetration interfaces.

The Containment penetrations interfaced with the Auxiliary Building and the Turbine Building (through the East and West Main Steam Valve Houses). Consequently, the FSS design employed the OpDCGLPN for the Containment penetrations, which was the most limiting.

The OpSOF for 326 of the 369 measurements taken, when compared against the OpDCGLPN for Containment penetrations were less than one (1). The mean OpSOF, using the OpDCGLPN for Containment penetrations was 0.564. Forty-three (43) measurements exceeded an OpSOF (when compared against the OpDCGLPN for Containment penetrations) of one with the maximum OpSOF for a single measurement of 8.600, with a corresponding BcSOF when compared against the Containment BcDCGLPN of 0.585. The complete tables containing the measurement results of all of the 369 measurements that were taken are presented in Attachment 2. The measurement data collected passed the Sign Test. The results of the Sign Test are provided in Attachment

3. The statistical summary of the measurement data taken, when compared against the BcDCGLPN for Containment penetrations are presented in Table 13.

Forty-three (43) measurements exceeded the OpDCGLPN but were less than the BcDCGLPN for Containment penetrations. The OpSOF (based on the OpDCGLPN) for a systematic or a judgmental measurement(s) may exceed one without remediation as long as the survey unit passes the Sign Test and, the mean OpSOF (based on the OpDCGLPN) for the survey unit does not exceed one. Once the survey data set passed the Sign Test (using OpDCGLPN), the mean radionuclide activity (pCi/m2) for each ROC from systematic measurements along with any identified elevated areas from systematic and judgmental measurements were used with the BcDCGLPN to perform a mean BcSOF calculation. The mean BcSOF for the Unit 1 Containment Penetrations was adjusted to

[30]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 include the dose from elevated measurements using Equation 5-6 from LTP Chapter 5, section 5.5.5, reproduced as Equation 4. The mean BcSOF for the survey unit was then adjusted by adding the SOF from the elevated areas to the mean to account for the additional dose attributed to the elevated areas.

None of the 43 identified elevated penetrations interfaced with the Turbine Building. The adjusted surface area of the Unit 1 Containment Penetrations FSS unit (SASU) was 254.77 m2. The surface area of each of the elevated measurements was 0.559 m2, which equates to the FOV of each individual static measurement. The individual elevated SOF for each elevated ROC were than summed to provide a total SOF adjustment due to each of the 43 elevated measurements.

BcSOFEP/PN = BcSOF for embedded pipe or penetration survey unit within a basement using BcDCGLs Mean ConcEP/PN ROCi = Mean concentration for the systematic measurements taken during the FSS of embedded pipe or penetrations in survey unit for each ROCi BcDCGLEP/PN ROCi = BcDCGLEP/PN for for embedded pipe or penetration for each ROCi Elev ConcEP/PN ROCi = Concentration for ROCi in any identified elevated area (systematic or judgmental)

SAElev = surface area of the elevated area SASU = surface area of FSS unit The calculation to derive the adjustment to the mean BcSOF is presented in Attachment

2. The mean BcSOF for Containment penetrations was adjusted by a value of 0.001 to account for the identified elevated measurements. The adjusted mean BcSOF for Unit 1 Containment was 0.040, which equated to the dose assigned to the survey unit of 0.995 mrem/yr. This value is the dose assigned to the survey unit based on the average of the systematic measurements adjusted for the dose contribution of the identified elevated measurements. In accordance with LTP Chapter 6, section 6.4.5, the SOF of 0.040 or a dose value of 0.995 mrem/yr will be added to the Unit 1 Containment basement as well as the Auxiliary Building basement and the Turbine Building basement.

[31]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 The OpSOF for one hundred forty five (145) measurements, when compared against the OpDCGLB for Containment basement surfaces was above one (1). Consequently, in accordance with LTP Chapter 5 section 5.5.5, twenty seven (27) of the penetrations required grouting. However, twenty two (22) of 27 penetrations that exceeded the criteria were physically removed and disposed of as waste during building demolition.

Only the remaining five (5) Unit 1 Containment Building Penetrations were actually grouted. No dose reduction was attributed to the survey unit because of grouting.

8. QUALITY CONTROL In compliance with ZS-LT-01, replicate measurements were performed on 5% of the survey locations chosen at random. Nineteen (19) replicate measurements were taken, which equates to 5.14% of the total number of measurements and satisfies the requirement. Using the acceptance criteria specified in section 4.1.2 of ZS-LT-01, there was acceptable agreement between the replicate readings and the original readings. Refer to Attachment 4 for quality control analysis results.

9. INVESTIGATIONS AND RESULTS No investigations were performed during the performance or analyses of the FSS.

10. REMEDIATION AND RESULTS No radiological remedial action as described by MARSSIM Section 5.4 was performed in this survey unit prior to or as a result of the FSS.

The FSS of the Unit 1 Containment penetrations was performed prior to the demolition of the Unit 1 Containment dome to the 588 foot elevation. During the course of the demolition, 22 of the 61 penetrations were completely removed and disposed of, including the wall surfaces where they were located. No dose was subtracted from the survey unit due to this action.

11. CHANGES FROM THE FINAL STATUS SURVEY PLAN There were no addendums to the FSS plan.

12. DATA QUALITY ASSESSMENT (DQA)

The DQO sample design and data were reviewed in accordance with ZionSolutions procedure ZS-LT-300-001-004, Final Status Survey Data Assessment for completeness and consistency. Documentation was complete and legible. Surveys and

[32]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 measurement collection were consistent with the DQOs and were sufficient to ensure that the survey unit was properly classified.

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

The preliminary data review consisted of calculating basic statistical quantities (e.g.,

mean, median, standard deviation). All data was considered valid including negative values, zeros, values reported below the MDC, and values with uncertainties greater than two standard deviations. The mean and median values for each ROC were well below the respective OpDCGLs. Therefore, the survey unit meets the unrestricted release criteria with adequate power as required by the DQOs.

The data for Co-60 and Cs-137 is represented graphically through a frequency plot and a quantile plot. All graphical representations are provided in Attachment 5.

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

14. CONCLUSION Survey Unit 01112 has met the DQOs of the FSS plan. The ALARA criteria as specified in Chapter 4 of the LTP were achieved. The elevated measurement concentration (EMC) is not applicable to structural surfaces.

The survey unit was properly classified as Class 1. All identified ROC were used for statistical testing to determine the adequacy of the survey unit for FSS. Three hundred and sixty-nine (369) measurements were obtained. Evaluation of the data shows that none of the ROC concentration values exceed the OpDCGLPN or any investigational levels in 326 of the 369 measurements taken. Forty-three (43) measurements exceeded the OpDCGLPN but were less than the BcDCGLPN for Containment penetrations. The OpSOF (based on the OpDCGL) for a systematic or a judgmental measurement(s) may exceed one without remediation as long as the survey unit passes the Sign Test and, the mean OpSOF (based on the OpDCGL) for the survey unit does not exceed one. The FSS results produced a mean OpSOF of 0.564. In addition, the measurement data collected passed the Sign Test.

LTP Chapter 5, section 5.5.5 requires that the dose from elevated measurements be added to the mean dose for the survey unit affected. Forty-three (43) measurements exceeded the OpDCGLPN in penetrations that interfaced between the Containment and the Auxilairy Building. Consequently, the mean BcSOF was adjusted by a value of 0.020 to

[33]

FSS RELEASE RECORD UNIT 1 CONTAINMENT BUILDING PENETRATIONS SURVEY UNIT 01112 account for the identified elevated measurements. This value was then added to the mean BcSOF for the Unit 1 Containment Penetration FSS unit of 0.038 resulting in an adjusted total BcSOF for the Unit 1 Containment Penetration FSS unit of 0.059. This BcSOF equates to a dose of 1.468 mrem/yr.

LTP Chapter 6, section 6.4.5 requires that the dose from a penetration be added to each basement that the penetration interfaces with. The penetrations in Unit 1 Containment interface both with the Auxiliary Building and with the Turbine Building. Consequently, a dose value of 1.468 mrem/yr will also be added to the Auxiliary Building basement and the Turbine Building basement.

The null hypothesis was rejected. Therefore, in accordance with the LTP Section 5.10, survey unit 01112 meets the release criterion and is acceptable for unrestricted release.
