SUMMARY

This report presents the results and conclusions of the final survey conducted by Portland General Electric Company of support facilities and site grounds at Trojan Nuclear Plant. The final survey of the support facilities and site grounds commenced in July 2001. Final survey data collection was completed in November 2004. The final survey was performed in accordance with the final survey process described in PGE-1 061, "Trojan Nuclear Plant Defueled Safety Analysis Report and License Termination Plan (PGE-1078)," referred to as the LTP. The support facilities and site grounds were divided into 74 survey units, encompassing over 132,000 square meters of surface area, and classified according to their potential for containing residual radioactivity. Eight survey units were classified as Class 1, 12 survey units as Class 2, and 54 as Class 3. Survey data were collected from each survey unit according to data collection patterns and frequencies established for each classification. Scan measurements were performed over approximately 8 percent of the entire surface area and a total of 2,364 static measurements were collected as final survey data. In addition, 1,627 supplemental removable surface radioactivity measurements were collected. The final survey data demonstrate that each survey unit meets the radiological criteria for unrestricted use specified in 10 CFR 20.1402. Based on the results of the final survey, Portland General Electric Company concludes support facilities and site grounds meet the regulatory requirements for release to unrestricted use. v

1. INTRODUCTION 1.1 PURPOSE AND SCOPE This report presents the results and conclusions of the final survey of support facilities and site grounds. It provides the information required by 10 CFR 50.82(a)(I 1), which demonstrates that support facilities and site grounds meet the radiological criteria for unrestricted use specified in 10 CFR 20.1402. This report also documents the final survey was performed in accordance with the final survey process described in PGE-1061, "Trojan Nuclear Plant Defueled Safety Analysis Report and License Termination Plan (PGE-1078)," hereinafter referred to as the LTP.

1.2 DESCRIPTION

The support facilities, shown in Figure 1-1, include the Condensate Demineralizer Building (also known as the Radwaste Storage Building), Maintenance Building, Security Building (also known as the Access Control Facility), Trojan Central Building, Materials Warehouse, Technical Support Center (TSC), Chlorine Building, Guardhouse, Gas Bottle Storage Building, and Pebble Springs Warehouse. Also included as support facilities are the Containment Building Tendon Gallery, Intake Structure, Discharge & Dilution Structure, Circulating Water Pump Pit, transformer area, Oily Water Separator, Solids Settling Basin, and the exteriors of the Containment, Auxiliary, Fuel, Turbine, and Control Buildings. The site grounds consist of the Industrial Area grounds, excluding the yard area within and immediately adjacent to the ISFSI that were surveyed in 1996. Two areas outside the Industrial Area are included in the site grounds. They are the Pebble Springs Warehouse yard, since it was used to store radwaste boxes filled with concrete debris from inside the Containment awaiting shipment, and a smaller area north of the South Warehouse which was used to store concrete blocks removed from the Containment Building exterior wall. In their post-final survey configuration, the support facilities and site grounds exist largely as they did during plant operations, with the exception of the Condensate Demineralizer Building. The Condensate Demineralizer Building is a three-story, partially below grade structure located west of the Turbine Building. During plant operations, it contained the vessels, filters, and pumps that were used to demineralize the condensate. Once the plant shutdown, the equipment was removed from the building and it was used as a radwaste processing and storage facility. It now exists as an empty building. Support facilities and site grounds were prepared for final survey by a series of decommissioning activities, including radiological characterization, dismantlement and demolition, remediation, and turnover to final survey. A general description of these activities is given in Appendix A. Detailed decommissioning information as well as a brief radiological history is contained in the LTP, Section 3. Radiological characterization data were gathered and analyzed. The results guided decisions regarding the need for, extent of, and most effective means of remediation. Contaminated structures, equipment, and components were dismantled or demolished and 1-1

TRO JA N FlAA [, .LrrtRVFY RPPORT-S.S'PPORTFAMITItN A NDI)S RnT QTP lI) . removed for disposal. Remaining structure surfaces were remediated, as needed, and then systematically turned over for final survey. An assessment of the operational and radiological history established the initial classification of these areas. Support facilities and site grounds were divided into the four areas to facilitate survey preparation and final survey activities. The respective surface areas are shown in the following table. Surface Area of Support Facilities and Site Grounds Interior Surfaces Area (m') Support Facility Exteriors 57,000 Support Facility Interiors 28,859 Condensate Demineralizer Building Interior 4,114 Site Grounds 42,242 Total Surface Area: 132,215 1.3 SITE RELEASE CRITERIA The site release criteria applied to the final survey correspond to the radiological criteria for unrestricted use given in 10 CFR 20.1402, which are: I. Dose Criterion: The residual radioactivity that is distinguishable from background radiation results in a Total Effective Dose Equivalent (TEDE) to an average member of the critical group that does not exceed 25 mrem/yr, including that from groundwater sources of drinking water; and

2. ALARA Criterion: The residual radioactivity has been reduced to levels that are as low as reasonably achievable (ALARA).

1.3.1 APPLICATION OF THE SITE RELEASE CRITERIA Levels of residual radioactivity that correspond to the allowable radiation dose and ALARA levels of the site release criteria were derived by analysis of various scenarios and pathways (e.g., direct radiation, inhalation, ingestion) through which exposures could occur. These derived levels, referred to as Derived Concentration Guideline Levels (DCGLs), form the basis for the following four conditions which, when met, satisfy the site release criteria:

1. The average residual radioactivity above background is equal to or below the DCGL;

2. Individual measurements, representing small areas of residual radioactivity which exceed the DCGL, do not exceed the elevated measurement comparison DCGL; 1-2

TR(JAIM FAT. Sr4TR VFY RPFPRT-R.'7IPPORT FACrir.ITJF.P A4n .zITP (RfTWfn.l

3. Where one or more individual static measurements exceed the DCGL, the average residual radioactivity passes the Sign statistical test; and

4. Remediation is performed where it is ALARA to reduce the levels of residual radioactivity to below the concentrations necessary to meet the DCGLs.

The manner in which these conditions were met is described in Section 4.2. 1.3.2 DERIVED CONCENTRATION GUIDELINE LEVELS The residual radioactivity concentration levels on support facility equipment and structural surfaces were compared to a gross activity DCGL of 2 1,000 dpm/l00 cm2 . Areas within the Condensate Demineralizer Building were compared to a gross activity DCGL of 7,500 dpm/l 00 cm2 . For the Pebble Springs Warehouse, a gross activity DCGL of 22,000 dpm/l 00 cm2 was used. The gross activity DCGLs were derived for surface residual radioactivity and developed using the methodology described in the LTP, Section 4.2.3, based on the radionuclide-specific screening DCGLs given in the LTP, Table 4-1. The residual radioactivity concentration levels in the soil on the site grounds were compared to the radionuclide-specific screening DCGLs for volumetric residual radioactivity given in the LTP, Table 4-1, in a ivnity rule application. 1.3.2.1 Primary-to-Secondary System Leakage Gross Activity DCGL The gross activity DCGL of 2 1,000 dpm/I00 cm2 was developed for application to structures, such as support facilities, where the principal contamination mechanism would have been from primary-to-secondary system leakage. Samples were collected from representative structures or components associated with the secondary system where the radioactivity detected would be due to primary system leakage into the secondary system. The samples were used to establish the radionuclide distribution of surface residual radioactivity. The samples were sent to an offsite laboratory for analysis and the laboratory results were used to calculate a gross activity DCGL value for each sample. Several radionuclides of interest were detected in each of the samples. The single radionuclide detected in all the samples was ' 37Cs. It accounted for the highest activity concentration, ranging from 83 to 99% of the total activity, in all but one of the samples. In that one sample, 63Ni had the highest activity concentration and 13 7Cs accounted for only 31% of the total activity. For all samples, alpha emitters were either not detected by sample analysis or were detected at activity concentrations that are insignificant in terms of dose contribution. For purposes of calculating the DCGL, radionuclides of interest that were not detected were assumed present at their minimum detectable concentration (MDC). At their MDC, none of the radionuclides exceeded 10% of their respective screening DCGLs and therefore were not included in the DCGL calculation. There was some variability in relative radionuclide fractions when one sample was compared to another. Therefore, the most conservative calculated value, 1-3

TROJIAN FINV .R.rVJR VFY RFPORT- .U!IPPORT FACI lMRFS. AN ND SITF GROUINDS 21,000 dpm/100 cm2 , was selected as the gross activity DCGL.

1.3.2.2 Radiologicallv Controlled Area (RCA) DCGL The gross activity DCGL of 7,500 dpm/100 cm 2 was developed primarily for application to interior surfaces of the Auxiliary Building and related radiologically controlled areas (RCAs) such as the Condensate Demineralizer Building. Samples from nine locations were collected to conservatively represent the radionuclide distribution found on the interior surfaces of the Auxiliary Building. The sample locations were not biased towards any particular group of Auxiliary Building systems, rooms, or elevations. Sample locations were randomly selected from a population of areas on the floors and walls in the Auxiliary Building where fixed surface contamination was detected. The samples were collected prior to remediation and sent to an offsite laboratory for analysis. The laboratory results were used to calculate a gross activity DCGL value for each sample. Several radionuclides of interest were detected in each of the samples. The two radionuclides detected in all the samples were 63 Ni and "'Cs. They accounted for the highest activity concentrations, ranging from 76 to 100% of the total activity, in all but one of the samples. In that sample, 3H had the highest activity concentration of 49%, compared to 44% for 63 Ni and 137Cs combined. For all samples, alpha emitters were either not detected by sample analysis or were detected at activity concentrations that are insignificant in terms of dose contribution. For purposes of calculating the DCGL, radionuclides of interest that were not detected were assumed present at their minimum detectable concentration (MDC). They were included in the DCGL calculation where their MDC exceeded 10% of their respective screening DCGLs. There was some variability in relative radionuclide fractions when one sample was compared to another. Therefore, the most conservative calculated value, 7,500 dpm/1 00 cm2 , was selected as the gross activity DCGL. The radionuclide distribution assumed for this DCGL is shown in the following table. 14

1.3.2.3 Containment Gross Activity DCGL The gross activity DCGL of 22,000 dpm/I 00 cm 2 was developed for the Containment building interior. It was applied to the Pebble Springs Warehouse, which was used to store radwaste boxes filled with concrete debris from inside the Containment awaiting shipment. Samples were collected from representative surfaces in the Containment prior to surface remediation and were used to establish the radionuclide distribution of surface residual radioactivity. The samples were sent to an offsite laboratory for analysis and the laboratory results were used to calculate a gross activity DCGL value for each sample. Several radionuclides of interest were detected in each of the samples. The predominant beta-gamma emitters were found to be 6 0Co and 13 7Cs. Alpha emitters were either not detected by sample analysis or were detected at activity concentrations that are insignificant in terms of dose contribution. The radionuclide detected with the highest activity concentration was 137CS, which accounted for between 81 and 98% of the total activity of each sample. For purposes of calculating the DCGL, radionuclides of interest that were not detected were assumed present at their MDC. They were included in the DCGL calculation where their MDC exceeded 10% of their respective screening DCGLs. There was some variability in relative radionuclide fractions when one sample was compared to another. Therefore, the most conservative calculated value, 22,000 dpm/100 cm 2 , was selected as the gross activity DCGL.

The measured radioactivity concentration levels were compared to the corresponding radionuclide-specific screening DCGL value for one or more of the radionuclides, given in the table below.

This value corresponds to the volumetric screening DCGL for 60Co and allowed the use of a sodium iodide (NaI) detector to measure gross gamma activity.

The total of the background count rate and the gamma count rate equivalent to the volumetric screening DCGL for 60Co resulted in a gross gamma activity value of 9,000 cpm for a NaI detector. 1-7

2. FINAL SURVEY DESIGN The final survey was designed and performed as described in the LTP, Section 4. The Data Quality Objectives (DQO) process was used to ensure that the final survey results were of sufficient quality to support the final decision. Support facilities and site grounds were divided into survey units of proper size, which were categorized and classified according to the type and potential for residual radioactivity. Instrumentation and survey methods, appropriate to the type of radiation being measured, were used to collect scan, static, and supplemental measurements. The measurements were collected in accordance with administrative and quality controls instituted to provide assurance of accurate results.

2.1 SURVEY UNITS Support facilities and site grounds were divided into 74 survey units based on the physical characteristics, the potential for elevated residual radioactivity, and the size of the area with similar potential for residual radioactivity. 2.1.1 CATEGORY Survey units were assigned to one of the following two categories based on the physical characteristics and the type of residual radioactivity present:

• Structures with surface residual radioactivity where a gross activity DCGL was applied. This type included structural floor, wall, and ceiling surfaces. There were 66 survey units in this category.
• Areas and materials with volumetric residual radioactivity where the radionuclide-specific screening DCGLs for volumetric residual radioactivity were applied. This type included the site grounds. There were eight survey units in this category.

2.1.2 CLASSIFICATION Survey units were classified as Class 1, Class 2, or Class 3 based on the potential for residual radioactivity. Areas with residual radioactivity that exceeded the DCGL prior to remediation were divided into eight Class 1 survey units. Areas with residual radioactivity detectable above background levels, but that did not exceed the DCGL prior to remediation, wVere divided into 12 Class 2 survey units. Areas with residual radioactivity not expected to be detectable above background levels were divided into 54 Class 3 survey units. The classification process incorporated the working hypothesis that all areas had a potential for residual radioactivity above the DCGL. This initial assumption meant that a survey unit was initially considered Class 1 unless a basis for classification as Class 2 or Class 3 was identified. Early in the final survey planning process, little or no characterization data were available. Elevated radiation levels from contaminated surfaces, components, and equipment prevented the collection of meaningful radiological data. Some surfaces were physically inaccessible. 2-1

TR y NFPWAT. S!RVEY RFPoRT-rsCjPPoRTFACIYITu7PFs A .rsTPaRnT fnl During the course of decommissioning, the contaminated components and equipment were removed, surfaces were made accessible, and a substantial amount of characterization data was collected. The data, summarized in Table 2-2, showed that these areas could be properly classified as Class 2 or Class 3. This approach was consistent with that described in the LTP, in which areas are initially considered Class 1 areas unless a basis for classification as Class 2 or Class 3 is identified. Both scan and static measurement data collected during final survey confirmed the classification decisions made. 2.1.3 SURVEY UNIT SIZE Survey units were sized to ensure that survey data points were relatively uniformly distributed among areas of similar potential for residual radioactivity. Survey units were designed to have relatively simple shapes unless an unusual shape was appropriate for the operational history of the area. Where possible, existing building characteristics such as horizontal and vertical structural supports, walls, and rooms were used to define the boundaries of the structure survey units. A similar approach was applied to the land area survey units. Support facilities were divided into survey units ranging in size from 33 to 9,460 M2 . Class 1 structure survey units were 100 m2 in floor area or less. Class 2 survey units were 417 m2 in floor area or less. Class 3 survey units were 7,332 m2 in floor area or less. Site grounds were divided into survey units ranging in size from 300 to 21,694 m2. Class 1 survey units were 1,551 m2 in land area or less. Class 2 survey units were 4,856 m 2 in land area or less. Class 3 survey units were 21,694 m2 in land area or less. 2.1.4 IDENTIFICATION NOMENCLATURE Each survey unit was identified by a seven-digit identification code. The first digit represents the survey unit category. One of two category codes was used: S - structure with surface residual radioactivity G - ground/land area or materials with volumetric residual radioactivity The next two digits represent the reference map identification code.

Commercially available radiation detection and measurement instrumentation was selected based on reliable operation, detection sensitivity, operating characteristics, and expected performance in the field. Radioactive sources used for calibration purposes are traceable to the National Institute of Standards and Technology (NIST). 2.2.1 PORTABLE INSTRUMENTATION Scan and static surface radioactivity measurements were performed using the Ludlum Model 2350-1 data logging survey meter with one of three types of Ludlum detectors: gas-flow proportional (GFP), Geiger-Mueller (G-M), or scintillation. Table 2-1 gives the model number and a description of the detectors used. 2-3

A total efficiency was established for each detector used to measure beta radiation. The total efficiency is the product of the instrument efficiency and the source (or surface) efficiency for a specified survey geometry or measurement technique. The instrument efficiency, i.e., the ratio between the net count rate of the instrument and the 2n surface emission rate of a radiation source, was determined by counting the source with the detector in a fixed position from the source (reproducible geometry). A jig was used to create the reproducible geometry and a source to detector distance of 1 cm was normally used. A value of 0.5 was used for the source efficiency for smooth surfaces; a value of 0.3 for concrete scabbled surfaces. These values were established based on beta energies of the expected radionuclide distribution and on surface geometry considerations. The source efficiency for beta particle emission is the ratio between the number of radiation particles emerging from the measurement surface of the area being surveyed (the source) and the total number of radiation particles being released within that source per unit time. 2.2.1.2 Instrument Response Instrument response was checked before and after instrument use each day. A check source was used that emitted the same type of radiation (i.e., beta or gamma) as the radiation being measured and that gave a similar instrument response (see the preceding table). The response check was performed using a specified source-detector alignment that could easily be repeated. If the instrument failed its response check, it was not used until the problem was resolved. Measurements made between the last acceptable response check and the failed check were evaluated and, if appropriate, discarded. 2-4

TROIYA N WA T 5AVL'IRVFY REPORT- SI IPPORTFAC7II TIPV AXn RITF G(ROLIf.V 2.2.1.3 Minimum Detectable Concentration A minimum detectable concentration (MDC) was determined for each instrument and scan and static measurement method that were used for survey data collection. Instruments used for scan measurements were capable of detecting radiation of interest to an MDC of less than 50% of the DCGL at a scan rate of 5 cm/sec for beta and 0.5m/sec for gamma. The exception to this was the Model 44-9 pancake GM detector, which typically could not achieve a scan MDC of less than the DCGL. Where this detector was used, the survey design prescribed compensatory measures that included using a lower scan rate (i.e., 3 cm/sec), limiting the size of the survey unit area, and/or increasing the number of static measurements. Instruments used for static measurements were capable of detecting radiation of interest to an MDC of less than 45% of the DCGL with a count time of one minute. 2.2.2 LABORATORY INSTRUMENTATION On-site laboratory instruments were used to perform gamma spectroscopy of soil and gravel samples and gas proportional counting of removable surface radioactivity samples (smears). Removable surface radioactivity measurements were performed using the Tennelec Model LB5100 GFP alpha/beta counting system. Volumetric residual radioactivity measurements were made using the Canberra Genie-2000 spectroscopy counting system with an Ortec high-purity germanium detector.

A QC standard was used that emitted the same type of radiation (i.e., beta or gamma) in the same type of counting geometry as the radiation being measured. Count results were compared to the mean of a QC data set. The results were also graphed and reviewed for trends in detector performance. No count results fell outside the acceptable QC band and no negative trends were identified in instrument performance. 2.2.2.3 Minimum Detectable Concentration Laboratory instruments used for removable surface radioactivity measurements were capable of detecting beta radiation to less than 1% of the DCGL with a two minute count time. Laboratory instruments used for gamma spectral analysis measurements were capable of detecting gamma-emitting radionuclides to an MDC of less than 5% of the DCGL with a count time of 20 minutes. 2.3 SURVEY METHODS Survey methods, as described in the following sections, were applied to collect scan and static measurements of surface and volumetric residual radioactivity, and removable surface radioactivity measurements from structural surfaces. 2-6

TROfA? FIV RIAL .IRVFY RRPORT-.V1TPPORT FAC'7LTIF. An X 'VTlrOF GRTWf.VS 2.3.1 SCAN MEASUREMENTS Scan measurements were performed to locate radiation anomalies that might indicate elevated areas of residual radioactivity that require further investigation. The level of scan coverage was proportional to the potential for finding elevated areas of residual radioactivity based on the history of the survey unit. Where no remediation had occurred, inaccessible surfaces or difficult to measure surfaces (e.g, inside cracks or small bore penetrations) were assumed to have the same level of residual radioactivity as that found on adjacent accessible surfaces. Accessible surfaces were surveyed the same as other structure surfaces. Where remediation had occurred, an approximation of the residual radioactivity on the inaccessible surface was made and the accessible surfaces were surveyed the same as other structure surfaces except that they were included in the scan coverage area when scanning was done at less than 100% coverage (i.e., Class 2 survey unit). 2.3.1.1 Scan Coverage Scan measurements of Class 1 survey units were performed over 100% of the surface/land area. Scan measurements of Class 2 survey units were performed over 10 to 50% of the surface/land area. For Class 3 survey units, scan measurements were performed over 10% or less of the surface/land area. In Class 2 and Class 3 survey units, those areas with the highest potential for elevated residual radioactivity (e.g., walkways, corners, remediated surfaces), based on professional judgment, were selected for scanning. The percent of scan coverage was determined based on the number and size of the selected areas. 2.3.1.2 Surface Residual Radioactivity Structure surfaces were scanned for beta-emitting radionuclides. Typically, the detector was held less than 2 cm from the surface and moved at 5 cm/sec over an area of one square meter. Once the selected area was scanned, the latched value was electronically entered into the data logger memory. As a matter of practice, the instrument ratemeter alarm was udsually set at approximately 0.8 times DCGL. The audible alarm would alert the surveyor that radiation levels are approaching the DCGL. The surveyor would respond by identifying the size of the area exceeding the alarm setpoint, mark the location in the field, and then attempt to capture the maximum radiation level within the elevated area. An investigation was performed where the maximum radiation level exceeded the investigation level. Normally, the Ludlum Model 43-68 GFP detector with the data logger in ratemeter latching mode was used. For areas with size or geometry constraints, the Ludlum Model 43-116-1 GFP detector or Model 44-9 pancake G-M detector was used. Surfaces were not scanned for alpha-emitting radionuclides. Radiological characterization data indicated that alpha emitters were either not present or were present at activity concentrations that were insignificant in terms of dose contribution. Therefore, alpha-specific measurements of surface residual radioactivity were not performed. 2-7

The Ludluhi Model 44-10 NaI scintillation detector with the data logger in ratemeter latching mode was used. Typically, the detector was held close to the surface, usually less than 6 cm, and moved in a back and forth (left to right, right to left) while the surveyor walked slowly over the area at a scan rate of approximately 0.5m/sec in a systematic pattern. Once the area was scanned, the latched value was electronically entered into the data logger memory. As a matter of practice, the instrument ratemeter alarm was usually set at the gross activity value of 9,000 cpm (see Section 1.3.2.5). The audible alarm would alert the surveyor that radiation levels are approaching the DCGL. The surveyor would mark the location and then attempt to capture the maximum radiation level within the elevated area. A soil or gravel sample was collected at or near the location and an investigation was performed where the volumetric residual radioactivity in the soil or gravel sample exceeded the DCGL. 2.3.2 STATIC MEASUREMENTS Static measurements of surface and volumetric residual radioactivity were collected at a frequency and at representative locations throughout the survey unit such that a statistically sound conclusion regarding the radiological condition of the survey unit could be developed. 2.3.2.1 Surface Residual Radioactivity Static measurements to detect beta-emitting surface residual radioactivity on structure and plant system surfaces were normally collected using the Ludlum Model 43-68 GFP detector with the data logger in scaler mode. For areas with access or geometry constraints, the Ludlum Model 43-116-1 GFP detector, Model 44-9 pancake G-M detector, or Model 44-116 beta scintillation detector was used. For each discrete measurement, the detector was placed on or near the surface to be measured, a one-minute count was taken, and the value was electronically entered into the data logger memory. 2.3.2.2 Volumetric Residual Radioactivity Soil and gravel samples were collected from areas that measured approximately 30 cm x 30 cm and taken to a depth of no more than 15 cm. A sufficient volume of material was collected at each sample location to fill a 1-liter Marinelli container. These samples were quantitatively analyzed onsite by gamma spectroscopy for gamma-emitting radionuclides of interest. Where required by the survey design, an additional sample of 100 ml in volume was collected at each static measurement location and quantitatively analyzed by an offsite vendor for tritium and 14C. 2.3.2.3 Number of Measurements To simplify the final survey process and to ensure conservatism without an associated unreasonable expenditure of resources, a minimum number of 30 static measurements per survey unit were collected. This number of measurements provided a sample population of sufficient size to assure statistical confidence in the conclusions drawn from the survey data. 2-8

A random number generator provided the coordinates of the starting point. Subsequent measurement locations were distributed around the starting point in a systematic pattern across the survey unit area. In some cases, this led to more than the minimum number of 30 static measurements being collected. For Class 3 survey units, measurement locations were selected using the random selection process (i.e., the reference coordinate system and a random number generator). A random number generator provided the coordinates of each measurement location. Measurement locations that did not fall within the survey unit area or that could not be surveyed due to health and safety considerations were replaced with other measurement locations determined using the random selection process. 2.3.3 SUPPLEMENTAL MEASUREMENTS Supplemental measurements to detect removable beta-emitting surface residual radioactivity on structure and plant system surfaces were collected at static measurement locations. These measurements (i.e., smears) were collected to verify removable surface radioactivity was no more than 10% of the gross activity DCGL. Smears were counted onsite using the Tennelec Model LB5 100. 2.3.4 MEASUREMENT LOCATION IDENTIFICATION Measurement locations were clearly identified andcdocumented to ensure they could be relocated if necessary. Actual measurement locations were permanently marked in the field and on survey maps. A unique number identifies each measurement location. The number convention, described in Section 2.4.4, allows survey data to be referenced to specific measurement locations identified on the photographs, drawings, or maps of the survey unit. Physical gridding was used where practical and useful. It provided a mechanism for referencing scan measurements to a specific location. Permanent marker was used to mark the physical grid layout. The basic grid pattern used was a one-meter square grid. 2.4 SURVEY PERFORMANCE 2.4.1 SAMPLE HANDLING Smear and soil/gravel samples collected for laboratory analysis were tracked. When sample custody was transferred (e.g., when samples were sent to the lab for analysis), a sample tracking record accompanied the sample for tracking purposes. The sample tracking (or chain of custody) 2-9

TR()IAM IVFlALT STIRVFYREPORT-.1IIPPORTF4IlfIT!FP?AMf.VSITT GYROtnf.n record documented the custody of samples from the point of collection until final results were obtained. 2.4.2 DATA INVESTIGATION Locations, identified by scan or static measurements, with residual radioactivity that exceeded the DCGL were marked and investigated. Scan measurements were performed over 100 percent of the area being investigated. Static measurements in the form of scalar or integrated counts were performed at locations with the highest concentration of residual radioactivity. Where gamma scan measurements were performed, the gross activity value of 9,000 cpm (see Section 1.3.2.5) was used to identify areas that may have contained elevated volumetric residual radioactivity. A soil or gravel sample was collected at locations that exceeded the gross activity value and the results reviewed to determine whether the residual radioactivity exceeded the DCGL and required an investigation. Two standard operating practices were found to cause significant overestimates in the level of residual radioactivity at locations identified for investigation. These practices are: (1) using gross cpm instead of net cpm to convert to dpm, and (2) converting the area of elevated residual radioactivity to 100 cm2 when the measured area is much smaller than that. For example,. assuming an instrument background of 35 cpm and an efficiency of 0.1, area with a "true" level of residual radioactivity of 5,000 dpm distributed over 15 cm2 (the active area of a pancake G-M detector) yields a converted value of over 35,000 dpm/l00 cm2. To avoid such significant overestimates, instrument background was subtracted from measurements exceeding the investigation level and an area correction was applied to elevated areas less than 100 cm2 in size. The results of the data investigations are summarized in Table 3-2. The details of the investigations are included in survey unit summary reports (see Appendices D and E). Depending on the results of the investigation, the identified areas within the survey unit were remediated, reclassified, and/or resurveyed. 2.4.3 DATA RECORDING Measurement data were corrected for instrument efficiency, source efficiency, detector area, and measurement size as applicable, and recorded in units appropriate for comparison to the DCGL, with the exception of gamma scan measurements, which remained in uncorrected units of gross cpm. The recording units were dpm/l 00 cm2 for surface residual radioactivity and pCi/g for volumetric residual radioactivity. Measured numerical values were recorded and included values below the MDC. Instrument and material backgrounds were generally not subtracted from residual radioactivity measurements gathered using portable instrumentation (see exception in Section 2.4.2). Instrument background was subtracted from measurements analyzed using laboratory instrumentation. Measurement results stored as final survey data constitute the final survey of record and are included in the data set for each survey unit. The data were used for calculations to determine compliance with the site release dose criterion. The affected data were stored as characterization data where a survey unit was remediated and/or reclassified during final survey. 2-10

TRO JAN FINA. 5T.SRVFY RFPORT- S.IPPORTRFACI4rU7R ATF.Vl) .aITP CROWDSI) 2.4.4 DATA MANAGEMENT The Survey Data Management System (SDMS) was used to store and process survey data. The SDMS is an electronic database that contains the final survey data and constitutes the quality record. Administrative controls for maintaining data integrity were incorporated into the software design. SDMS applications were tested as part of two separate tests: factory acceptance testing performed by the vendor and site acceptance testing performed by the Final Survey organization. A test plan and procedure were developed and documented for each functional module. Documented test results include the acceptance test objectives, test results, test discrepancies, and corrective actions taken to resolve the discrepancies. Raw survey data captured in the Ludlum Model 2350-1 data logger were downloaded, electronically converted to recording units, and uploaded to the SDMS. Other data, such as laboratory data, were manually entered into the SDMS for analysis. For electronic storage and retrieval purposes, each survey measurement is identified by a unique 15-digit code. The first seven digits are the survey unit Identification (ID) code (see Section 2.1.4). The last eight digits are the measurement ID code. The first two digits of the measurement ID code identify the type of measurement, as shown in the following table, and the last six digits are the unique measurement location ID.

2.4.5 QUALITY CONTROL MEASUREMENTS Quality Control (QC) measurements were performed to identify, assess, and monitor measurement error and uncertainty attributable to measurement methods or analytical procedures used in the survey data collection process. Two types of QC measurements were performed on a routine basis: QC checks and repeat measurements. A third type of QC measurement, duplicate sample analysis, was performed but is relevant only to the soil/gravel areas. Duplicate sample analysis is performed for volumetric (not surface) residual radioactivity. Acceptance criteria were met and no discrepancies were identified. 2-11

A N FWNA [.r IMVFY RFPORT-,.SUPPORT FPCIITIPFSI AX ND SITF GROTWflS. 2.4.5.1 OC Checks Seven direct observations of survey set-up and close-out activities and scan and static measurements were performed. The observations were reviewed with the surveyors and follow-up actions such as on-the-spot correction, surveyor refresher training, changes in work process, development of good practices, and procedural corrections and improvements were taken. 2.4.5.2 QC Repeat Measurements A set of fifteen repeat measurements was collected at a single static measurement location with measured residual radioactivity of 15,000 dpm/100 cm2 . The mean value was calculated and compared to the original measurement value. Measurement accuracy was deemed acceptable where the original measurement fell within +/-20% of the mean of the repeat measurement data set. The original measurement for the selected measurement location met the QC acceptance criterion. Repeat measurements are collected at static measurement locations with residual radioactivity greater than 5,000 dpm/100 cm2. Only the single location was eligible (i.e. had residual radioactivity greater than 5,000 dpm/1 00 cm2). No other static measurement locations were eligible. 2.4.5.3 Duplicate Sample Analysis A matrix-spiked sample was analyzed and the results compared to analysis results provided by an independent laboratory. For QC purposes, matrix spiked samples were used in lieu of split samples, due to the relatively low and non-uniform levels of volumetric residual radioactivity expected in the bulk material samples. Blind soil samples containing radionuclides of interest, specifically 6 0 Co, 134 CS, and 1 37 Cs, at environmental levels (0.1 to 1.0 pCi/g) were sent to Trojan for sample analysis by gamma spectroscopy. The analysis results were sent to the independent laboratory, who compared Trojan's analysis results to their analysis results. Measurement accuracy was deemed acceptable where Trojan's measured value fell within +/-20% of independent laboratory's reported value. The results met the QC acceptance criterion. 2.4.6 PROCEDURES Final survey activities were implemented and controlled using approved plant procedures. A list of those procedures is given in Table 2-3. 2.4.7 TECHNICAL BASIS DOCUMENTS Calculations and memoranda were prepared to document methods that were used, how the methods were derived, underlying assumptions for decisions that were made, the basis for deviations, and other information that warranted documentation.

Scan measurements were performed over 7,667 in2 and a total of 324 static measurements were collected. A single area of elevated residual radioactivity was identified. Data investigations revealed approximately 1 m 2 of land area with residual radioactivity above the DCGL. The area identified as elevated was located in a Class 2 survey unit (G51045B). The area was reclassified to Class 1 and a new Class 1 survey unit (G51045F) was created. The EMC was applied to the area with residual radioactivity above the DCGL. For Class 1 survey units, the land area of each survey unit ranged from 300 to 1,551 m2 . Gamma scan measurements were performed over 100% of the land area, with results ranging from 6,200 to 13,000 gross cpm (9,000 gross cpm is approximately equal to the DCGL). Static measurements were collected from 30 to 41 locations in each survey unit, with results ranging from 0.007 to 0.95 (unity rule applied). Average measured values ranged from 0.023 to 0.047. 3-2

4. DATA ASSESSMENT Final survey data were reviewed to ensure that they were of a sufficient type, quantity, and quality such that conclusions could be drawn with confidence regarding the radiological condition of the survey unit. Conclusions were drawn and documented in a separate release record prepared for each survey unit. A summary of the release record for each survey unit is given in Appendices B through E.

4.1 DATA VERIFICATION AND VALIDATION Data were reviewed to verify Data Quality Objectives (DQOs) established in the final survey design were met. Graphical representations and statistical comparisons of the data were made which provided both qualitative and quantitative information about the data. An assessment was performed to verify the data supported the underlying assumptions necessary for the statistical tests, if applicable. 4.1.1 DATA QUALITY The final survey data were verified authentic, appropriately documented, and technically defensible. Specifically, the following conclusions were made:

1. The instruments used to collect the data were capable of detecting the radiation of interest at or below the investigation level.

2. The calibration of the instruments used to collect the data was current and radioactive sources used for calibration were NIST traceable.

3. Instrument response was checked before and, where required, after data collection each day.

4. The MDCs and the assumptions used to develop them were appropriate for the instruments and the survey methods used to collect the data.

5. The survey methods used to collect the data were appropriate for the media and types of radiation being measured.

6. Special measurement methods used to collect the data were applied as warranted by survey conditions.

7. The custody of samples collected for laboratory analysis was tracked from the point of collection until final results were obtained.

8. The final survey data set consists of qualified measurement results that are representative of the current facility status and randomly collected as prescribed

         -      by the survey design.

A frequency plot was used to examine the general shape of the data distribution. 4.1.3 BASIC STATISTICAL COMPARISONS Statistical quantities (range, median, and standard deviation) were calculated for the final survey data set for each final survey unit. The calculated quantities were compared to the test values shown in the following table. Basic Statistical Comparisons Statistical Quantity Test Value Failure Response Range (R) R < 5a Examine data for outliers Median (U) I (ii - mean) / a I< 0.5 Examine data for outliers and anomalies Standard Deviation (a) a < 0.2 x DCGL Determine if more measurements are necessary Where the statistical quantity failed the comparison, the data set and/or survey design assumptions were examined. The statistical quantity failures are summarized in Table 4-1. 4.1.3.1 Range Test Where the range was greater than 5 standard deviations, the data were examined for outliers. Outliers usually represented true extreme values of a distribution, such as areas of elevated residual radioactivity, and indicated more variability in the population than was expected. There were 10 range test failures; however, no data were discarded. The failures were generally caused by a very tight distribution with a single outlier with elevated results relative to the rest of the data set. 4.1.3.2 Median Test Failure of the median test indicates large differences between the mean and the median and is an indication of the skewness in the data, warranting an examination of the data for outliers or anomalies. There was a single median test failure; however, no data were discarded. The failure was the result of a right-skewed data set where certain measurement locations were affected by gamma shine from the spent fuel pool (data were collected while pool was still in use). 4.1.3.3 Standard Deviation Test Where the value of the calculated standard deviation was larger than that estimated in the survey design (the initial design value was 0.2 x DCGL), an insufficient number of measurements may 4-2

As an additional measure of assurance, a retrospective power analysis was performed to verify the power of the Sign test would have been sufficient based on a minimum of 30 measurements collected and an actual standard deviation larger than that estimated in the survey design. The largest standard deviation from actual survey data collected was used (survey unit S07019D) along with survey design values contained in LTP Appendix 4-1 to construct the power analysis. The results, shown in the table below, indicate that 15 measurements per survey unit would have provided a sample population of sufficient size to assure statistical confidence in the conclusions drawn from the survey data. Therefore, the number of measurements collected was in all cases adequate. Retrospective Power Analysis Data Parameter Value Standard Deviation (a) 0.3 x DCGL Lower Bound of Gray Region (LBGR) 0.4 x DCGL False Positive Decision Error (a) 0.05 False Negative Decision Error (J) 0.05 Minimum Size of Sample Population 15 4.2 SATISFACTION OF THE SITE RELEASE CRITERIA Four conditions were established that, when met, satisfy the site release criteria (see Section 1.3.1). These conditions were applied to each survey unit as shown in Table 4-2. 4.2.1 CONDITION #1- MEAN TEST Condition #1 requires that the average residual radioactivity above background be less than or equal to the DCGL. To determine if Condition #1 was met, the mean of the final survey unit data set for each survey unit was compared to 1.0 x DCGL (for unity rule applications, DCGL is 1.0). In all cases, the average residual radioactivity was less than 0.4 x DCGL. Therefore, each survey unit satisfies Condition #1. 4.2.2 CONDITION #2 - ELEVATED MEASUREMENT COMPARISON Condition #2 requires that individual measurements, representing small areas of residual radioactivity that exceed the DCGL, do not exceed the EMC DCGL. To determine if Condition #2 was met, the individual measurement in a single survey unit, S07019D, that exceeded the DCGL was compared to the EMC DCGL. In this case, the individual measurement was less than 0.5 x EMC DCGL.. Therefore, each survey unit satisfies Condition #2. 4-3

TROJAN FINAL SURVEY REPORT- SUPPORTFACILITIES AND SITE GROUNDS The EMC DCGL was developed using the methodology and the area factors provided in the LTP, Appendix 4-1. The radionuclide-specific area factors given in the LTP could not be used directly to develop the EMC DCGL since the gross activity DCGL was derived based on a radionuclide distribution and not on a single radionuclide. Instead, a weighting method was applied using the radionuclide distribution and the relative activity fractions used to derive the gross activity DCGL. The radionuclides of interest were those used in the derivation of the gross activity DCGL. Area factors for use with the RCA gross activity DCGL were calculated for areas of elevated residual radioactivity of 1 m2, 4 m, and 9 m2 in size. The area factors were 4.9, 1.3, and 1.0, respectively. As applied, areas smaller in size than 1 m2 were generally assumed to be 1 m2 and the I m2 value of 4.9 was used, resulting in an EMC DCGL of 37,000 dpm/100 cm2 (4.9 x DCGL). 4.2.3 CONDITION #3 - SIGN TEST Condition #3 requires that where one or more static measurements exceed the DCGL, the average residual radioactivity passes the Sign statistical test. To determine if Condition #3 was met, the Sign test was applied to the final survey data set for the single survey unit, S07019D, which had one static measurement above the DCGL. In this case, the average residual radioactivity passed the Sign statistical test. Therefore, each survey unit satisfies Condition #3. The Sign statistical test was applied to the final survey data set of only one survey unit since no other had one or more static measurements that exceeded the DCGL. In that case, the data provided statistically significant evidence that the level of residual radioactivity in the survey unit does not exceed the site release dose criterion. The decision that the survey unit is acceptable for unrestricted release can be made with sufficient confidence and without further analysis. The Wilcoxon Rank Sum (WRS) statistical test was not used. 4.2.4 CONDITION #4 - ALARA EVALUATION Condition #4 requires that remediation be performed where it is ALARA to reduce the levels of residual radioactivity to below the concentrations necessary to meet the DCGLs. The levels of residual radioactivity were considered ALARA once remediation actions, considered to be cost effective, were taken. To determine if Condition #4 was met, an ALARA evaluation was performed for every Class 1 or Class 2 survey unit. In all cases, the ALARA evaluation verified that remediation was performed where it was ALARA to do so. Therefore, each survey unit satisfies Condition #4. The ALARA evaluation ensured that: (1) residual radioactivity had been reduced to levels that are as low as reasonably achievable, and (2) efforts to remove residual radioactivity were commensurate with the level of risk the residual radioactivity poses. The ALARA evaluation examined various remediation actions to determine which actions, if any, have a net benefit in further reducing the levels of residual radioactivity. The evaluation compared residual radioactivity levels to calculated remediation levels (see Appendix A) for possible remediation actions. The remediation action was taken where the level of residual radioactivity exceeded the remediation level. Conversely, if the concentration was less than the remediation level, the level 4-4

5. FINAL SURVEY CONCLUSION The final survey of support facilities and site grounds was performed in accordance with the LTP and its implementing procedures. Final survey data of adequate quantity and quality were collected from each of the survey units. The survey data for each survey unit showed:

1. The average residual radioactivity, which included the background distribution, was less than 1.0 x DCGL.

2. Individual measurements, representing small areas of residual radioactivity that exceeded the DCGL, did not exceed the EMC DCGL.

3. Where one or more individual static measurements exceeded the DCGL, the average residual radioactivity passed the Sign statistical test.

4. Remediation was performed where it was ALARA to reduce the levels of residual radioactivity to below the concentrations necessary to meet the DCGLs.

These conditions satisfy the site release criteria established in the LTP and the radiological criteria for unrestricted use given in 10 CFR 20.1402 (see Section 1.3). Therefore, it is concluded that support facilities and site grounds are suitable for release to unrestricted use. 5-1

APPENDIX A SURVEY PREPARATION ACTIVITIES This appendix provides a general description of decommissioning activities in the nature of a historical assessment that was used to determine the final survey classification of each of the support facilities and site grounds. Detailed decommissioning information as well as a brief radiological history is found in the LTP, Section 3. Support facilities and site grounds were prepared for final survey by a series of decommissioning activities, including radiological characterization, dismantlement or demolition, remediation, and turnover to final survey. Radiological characterization data were gathered and analyzed. The results guided decisions regarding the need for, extent of, and most effective means of remediation. Areas were remediated as needed, and then systematically turned over for final survey. An assessment of the operation and radiological history established the initial classification of support facilities and site grounds. RADIOLOGICAL CHARACTERIZATION Radiological characterization of the support facilities and site grounds was completed in two phases. The initial radiological characterization was performed as Phase I. It is documented in the "Trojan Nuclear Plant Radiological Site Characterization Report," Revision 0.1, dated February 8, 1995. Phase II involved routine radiological surveys, referred to as operational surveys. These surveys were used to support dismantlement and remediation activities. Areas that were not, or could not be, surveyed during Phase I were surveyed during Phase II. Based on the surveys gathered as part of Phase II characterization, the predominant beta-gamma emitters were found to be 60Co and "'Cs. DISMANTLEMENT AND DEMOLITION ACTIVITIES Most of the components and equipment in the support facilities were left as found during plant operations. Equipment and components, as well as heavily contaminated concrete and masonry surfaces, primarily in the Condensate Demineralizer Building, were removed during decommissioning. REMEDIATION ACTIVITIES Remaining structural surfaces were remediated using a variety of techniques ranging from wiping to surface material removal. Removable surface radioactivity was remediated via simple means such as wiping down an area and vacuuming to collect dirt and loose radioactivity from recesses and corners. These were considered good practices and were typically applied. Concrete surfaces were remediated by scabbling. Abrasive blasting was used to remove fixed radioactivity from surfaces other than concrete. Remediation levels were established for various types of remediation actions such as scrubbing, abrasive blasting, and scabbling. Remediation levels were developed using an unbiased analysis A-1

They are based on the methodology and assumptions given in the LTP, Section 2.4.2. Where the level of residual radioactivity exceeded the remediation level, the remediation action was taken. Conversely, if the concentration was less than the remediation level, the level of residual radioactivity was considered ALARA and the remediation action was not performed. The remediation levels applied to the support facilities are given below.

TURNOVER A systematic approach was established for the turnover of support facilities and site grounds from the Decommissioning organization to the Final Survey organization. Dismantlement and remediation activities were completed in areas that could be isolated or controlled in such a manner as to minimize the potential for the reintroduction of contamination from ongoing decommissioning activities in adjacent or nearby areas. These work areas were then prepared for final survey data collection. Support facilities and site grounds were divided into 21 work areas, listed in the following table, each of which was turned over separately. Prior to turnover, a walkdown of the work area was performed when the final configuration was known, usually near or after the completion of dismantlement and remediation activities. The physical state of the area and the scope of work necessary to prepare it for final survey were assessed during the walkdown. Requirements for access, isolation, and control were also addressed during the walkdown. Support activities necessary to conduct the final survey, such as scaffolding, interference removal, and electrical tag-outs, were identified. Safety concerns such as access to confined spaces, high walls, and ceilings were also identified. Tools, equipment, and materials not needed for final survey data collection were removed. Housekeeping and clean-up activities were completed. Scaffolding and other temporary equipment needed for final survey data collection were put in place. Administrative and physical controls were instituted to minimize the possibility of introducing radioactive material from ongoing decommissioning activities in adjacent or nearby areas. These measures included A-2

SUMMARY

Survey Unit ID Code: S07019A Classification: Class 1 Survey Unit Name: Condensate Demineralizer Building Size (m2 ): 169 19' Elevation - Floor and Lower Walls - Col B and C/5 and 8 Judgmental and Miscellaneous Measurement Data Measurement Type: Surface Scanning Beta Scan Coverage (%): 100 Measurement Units: dpm/lOOcm 2 Investigation Level: 7,500 Minimum Value: 902 Maximum Value: 7,171 Measurement Type: Removable Beta Number of Measurements: 34 Measurement Units: dpm/lOOcm 2 Investigation Level: 750 Minimum Value: 37 Maximum Value: 86 Discussion of Anomalous Measurement Data Investigation Summary Reason for Investigation: Four scan measurements exceeded the investigation level. Elevated Measurement Comparison (EMC): DCGL (Investigation Level): 7,500 Measurement Units: dpm/1OOcm 2 Maximum Value: 8,353 Size of Area Exceeding DCGL (mi2 ): N/A Size of Survey Unit (m2): N/A Survey Unit Area >DCGL (%): N/A EMC Value: N/A Action Taken: Corrected measurement values for scan locations per guidance in memo FS-01 8-03. Replaced original scan results in SDMS with these results, which corrected to less than the investigation level. Basis for Action Taken: Technical basis memorandum FS-018-03 provides guidance for correcting SDMS determined scan results for locations that exceed the investigation level by subtracting instrument background from the field results.

Elevated Measurement Comparison (EMC): DCGL (Investigation Level): 7,500 Measurement Units: dpm/1 00cm2 Maximum Value: 8,146 Size of Area Exceeding DCGL (M2 ): N/A Size of Survey Unit (M2 ): N/A Survey Unit Area >DCGL (%): N/A EMC Value: N/A Action Taken: Corrected measurement values for scan location per guidance in memo FS-018-03; used similar method for elevated scan measurement obtained with a 43-68 gas flow proportional detector. Replaced original scan results in SDMS with this result, which corrected to less than the investigation level. Basis for Action Taken: Technical basis memorandum FS-018-03 provides guidance for correcting SDMS determined scan results for locations that exceed the investigation level by subtracting instrument background from the field results.

SUMMARY

Survey Unit ID Code: G51045B Classification: Class 2 Survey Unit Name: Tank Farm Yard Area #1 Size (m2 ): 2,743 Judgmental and Miscellaneous Measurement Data Measurement Type: Surface Scanning Gamma Scan Coverage (%): 50 Measurement Units: Gross cpm Investigation Level: 9,000 Minimum Value: 6,100 Maximum Value: 9,600 Discussion of Anomalous Measurement Data The gross activity value of 9,000 cpm was used to identify areas that may have contained elevated volumetric residual radioactivity. A soil or gravel sample was collected at the location(s) that exceeded the gross activity value and the results reviewed to determine whether residual radioactivity exceeded the DCGL and required an investigation. Investigation Summarv Reason for Investigation: A single area identified by scan measurement exceeded investigation level. Elevated Measurement Comparison (EMC): DCGL (Investigation Level): 11 Measurement Units: pCi/g 137Cs Maximum Value: 27.2 Size of Area Exceeding DCGL (m2 ): 1.1 Size of Survey Unit (m 2 ): 2,743 Survey Unit Area >DCGL (%): 0.04 EMC Value: N/A Action Taken: Remediated localized area of subsurface contamination and subdivided area out into a newly created Class 1 survey unit (G5 1045F). Deleted scan and static measurements that are no longer in survey unit and obtained replacement measurements. Basis for Action Taken: Small, localized area of elevated radioactivity exceeded the DCGL and required reclassification to Class 1. E-12
