The total area (OL1) including the soil and solid surface portions is approximately 11600 square meters . Portions of the solid surface (concrete, macadam, brick) are Classl and Class 2 survey areas. Because the survey area exceeds the size limitations in the SNEC LTP (Reference 3.5) Table 5-5 for maximum class 1 survey unit area, this survey area is subdivided into multiple survey units: OL1-7 is an existing excavation in the SNEC site area, that will be backfilled after survey. OL1 -8 through OL1 -13 are subdivisions of the large open land area and comprise the majority of the total surface area. These open land areas and the excavation are covered by other design calculations. Several additional areas comprise the residual exposed concrete and macadam surfaces:
1.1.1 PF1 is a pre-existing Class 1 survey unit for the PAF floor and includes the north edge of the PF1 portion of the slab- 37 m2 1.1.2 DB1 is a pre-existing Class 1 survey area for the DSB floorpad and door ramp. This area is further divided into two survey units due to LTP survey unit area limitations.
DBI-1(85 m2) and DB1-2 (109 m2) - 194 m2 total. DB1-1 includes the full width of the north edge of the DSB portion of the pad.
1.1.3 DB5 is a pre-existing Class I survey unit for the DSB carport floor - 54 M 2 1.1.4 SS12 is a pre-existing survey area for the SSGS boiler pad. This concrete, although it is in a Class 1 soil area, is classified as Class 3 in the LTP Table 5-2. This area is not included in this design, but will be covered in a separate design due to the current presence of a large 'PRI pile' in the survey unit.
1.1.5 MA8-6 through 13, 16, and 17: Ten survey units of the old parking lot and driveway macadam. Because of the 100 m2 survey unit limitation for class I surfaces, the surface was subdivided into ten approximately 100 m2 (or less) survey units. The pavement occupies all of, or a large portion of, grids AT131, AU127, AU128, AU129, AU130, AU131, AV130, AV131, AW131, AX131, AY131. These are all class 1 survey units due to verbal reports of minor remediation and due to their proximity to the C&A building, the barrel bunker, and containment. Total area is about 772 M2 .
General arrangement of these units is shown in the drawing Attachment 6-17.
1.1.6 MA8-16 and MA8-17 have about 4 to 6 inches of soil on top of the pavement. This soil is to be surveyed per E900-05-014 and then removed and placed in a PRI pile to allow the pavement survey per this design.
1.1.7 MA8 the Line Shack concrete including garage door ramps and sidewalks. This area is not specifically classified in the SNEC LTP (Reference 3.5) but is selected to be class 2 consistent with the class 3 classification of the line shack exterior and the class 1 assigned to the surrounding soil. This is a Class 2 survey unit with about 33 m2 total area.
1.1.8 MA8-15 is additional concrete surfaces around the CV. There is some SSGS concrete and additional small monoliths in OL1-9 NW of the CV. This small concrete area is not specifically addressed in the SNEC LTP but is assumed to be Class 1 due to proximity to the CV and is about 37 M2 .
1.1.9 A summary list of survey unit areas is included as Attachment 5-1.

SUMMARY
OF RESULTS The following information should be used to develop a survey request for this survey unit. The effective DCGLw value is listed below. This value is derived from previously approved derived values for OCV Yard Soil and Boulders", Attachment 2 in SNEC calculation E900-04-005 (Reference 3.15). The US NRC has reviewed and concurred with the methodology used to derive these values.
See Attachment 2-1 and Reference 3.9.
Table 1, DCGLw Values I Gross Activity DCGLw (dpm/100 cm')
26445 (19834 A.L.)
NOTE: A.L is the site Administrative ULmit (75% of effective DCGLw) 2.1 Survey Design 2.1.1 Scanning of concrete and macadam surfaces shall be performed using a L2350 with 43-68B large area gas flow Droportional counter calibrated to Cs-137 (see typical calibration information on Attachment 3-1).
2.1.2 The instrument conversion factor/efficiency (Et) shall not be less than that assumed on Attachment 3-1 as 23.9% - Cs-137.
2.1.3 Other instruments of the type specified in Section 2.1.1 above may be used during the final status survey (FSS), but must demonstrate detection efficiencies at or above the value listed in Section 2.1.2 above.
2.1.4 An efficiency correction factor (ECF) is applied to compensate for efficiency loss when surveying rough surfaces based on Reference 3.1 and Attachment 2-2.
2.1.5 The fraction of detectable beta emitting activity affects the efficiency and is determined by the nuclide mix. The mix detectable beta fraction is determined to be 60% based on Reference 3.15. Because the adjusted DCGLw used is based only on the modified Cs-137 DCGLw, the mix percentage is not applied to the adjusted surrogate DCGLw. The gross activity DCGLw, which would include all the low energy activity and would require mix percentage adjustment is considerable higher, at 44434 dpm 100cm2. The Cs-1 37 adjusted surrogate activity already accounts for the detectable beta yield of the mix.
2.1.6 The ECF is derived from Attachment 2-2 and Reference 3.10 based on a surface irregularity of 3 inches or less. This is conservative, as actual observed irregularity is typically less than one inch. Also, the loss of efficiency is based on moving the detector away from a 150 cm 2 source. If the area of the residual activity is larger, than the efficiency loss would be smaller due to the increase in 'field-of-view' of the detector.
SNEC CALCULATION SHEET Calculation Number Revision Number Page Number E900-05-015 0 Page 4 of 1 Subject OL1 Paved and Misc. concrete surfaces MA8, PF1, DB5, DB1 - Survey Design 2.1.7 Because the alarm point and MDCscan are based on the highly conservative surface irregularity of 3 inches (intended to bound all cases to simplify design and performance of the survey), where surfaces are much smoother (e.g. 1 inch irregularity or less per probe area) than this 3 inch variability, short (e.g. % to 1 inch) standoff support pegs may be attached to the 43-68 in order to reduce the possibility of mylar damage. These standoffs must only be used when the surface smoothness is well within the assumed 3 inch variability. Because the high surface irregularity is assumed and used for the efficiency of the instrument for the entire design, this standoff will not affect the assumed efficiency if limited as discussed above.

surface)
See Attachment 2-1, 2-2, and 4-1 for calculations 2.1.8 This MDCscan (shown in Attachment 4-1) is based on a 300 cpm background.
Typical backgrounds are similar to this value assumed, as shown in the variability data shown as 0CW" (closed window or shielded detector) in Attachment 8-2.
Unaffected material backgrounds were determined at the Williamsburg station, which resulted in a mean background value of 306 cpm +/- 34.5. On 3/7/05, measurements were collected on three different surfaces in OL1: the DSB pad, the old parking lot, and the SSGS boiler pad.
2.1.9 The 37/705 survey data shown as UOWf (open window or unshielded) is used for the variability assessment for the COMPASS determination of sample requirements and is shown in Attachment 8-2.
2.1.10 A background of 1300 cpm would still result in MDCscan less than about 50% of the DCGLw (Attachment 4-2). Since the Action level cited in Table 3, above, is total counts per minute including background, if local backgrounds significantly exceed the background count rate assumed for the MDCscan (about 300cpm see Attachment 4-1) contact the cognizant SR coordinator to determine need for additional background count rate adjustments.
2.1.11 The scan DCGLw Action Level listed in Table 3 includes 1200 cpm DCGL equivalent count rate from Attachment 4-1 and an estimated 250 cpm background . The DCGLw action level is based on fixed measurement and does not include 'human performance factors' or 'index of sensitivity' factors (see Reference 3.12).
SNEC CALCULATION SHEET Calculation Number Revision Number Page Number E900-05-015 0 Page 5 of 11 Subject OL1 Paved and Misc. concrete surfaces MA8, PFI, DB5, DBI - Survey Design 2.1.12 If a total count rate greater than the 'DCGLw action level" of Table 3 is encountered during the scanning process, the surveyor should stop and locate the boundary of the elevated area, and then perform a usecond phase" fixed point count of at least 30 seconds duration. If the second phase result equals or exceeds the uDCGLw action" level noted in table 3, the surveyor should then mark the elevated area with appropriate marking methods and document the count rate observed and an estimate of the affected area. Subsequent investigation may take the actual surface irregularity into account for the efficiency.
2.1.12.1 Class I concrete should be scanned to include 100% surface coverage at a scan rate of about 10 cm per second. All accessible surfaces are required to be scanned. See Attachment 1-1 for grid layout for the survey unit. Areas that cannot be accessed should be clearly noted along with the reason for not completing the scan in that area.
2.1.12.2 Class 2 concrete would normally be scanned to include 10% to 50%
surface coverage. Only the concrete around the line shack is class 2. Due to the small size of the unit and the distribution of small areas, the unit (MA8-
- 14) will be 100% scanned at a scan rate of about 10 cm per second. Areas that cannot be accessed should be clearly noted along with the reason for not completing the scan in that area.
2.1.12.3 See Attachment 1-1 for grid layout for the survey unit.
2.1.12.4 The surfaces of the concrete or other pavement materials should be clear of debris to ensure detection parameters are not affected.
2.1.13 The minimum number of fixed measurement sampling points indicated by the COMPASS computer program (Reference 3.3) is 11 for each survey unit (see COMPASS output on Attachment 7-1 to 7-5). Fixed point measurements should be lAW Section 2.2. The MDCscan (concrete) is below the effective administrative DCGLwcsI-137 (4634 DPM1100cm2 MDCscan @300cpm bkg < 19834 DPM/100cm2 AL).
2.1.14 The minimum number of fixed point samples is increased to 13 (18% increase) for survey unit DB1-2 due to the slightly oversized (109 M2, 9% over LTP guideline) area of the unit. This oversize is due to the selection of a grid line as the separation point between DB1-1 and DB1-2. Survey Unit DB1-1 is only 85 i 2 . Since both units are class 1, the DSB pad will be 100% scanned regardless of the survey unit separation. Relocation of the arbitrary separation line could make these both equal and <100m 2 but is not considered to be useful since: separation on a grid line simplifies survey layout, the two units combined are <200 M2 , and the two units combined have more than the required number of fixed points (26 total vs. 22 required per MARSSIM).
2.1.15 One Biased direct measurement point is placed in DB1-1 on the face of the exposed slab. This point should be taken centered vertically on the vertical face at the 128 grid line.
.SNEC CALCULATION SHEET Calculation Number Revision Number Page Number E900-05-015 0 Page 6 of 11 Subject OL1 Paved and Misc. concrete surfaces MA8, PF1, DB5, DBI - Survey Design 2.1.16 VSP (Reference 3.4) is used to plot all sampling points on the included diagrams.
The actual number of random start systematically spaced measurement points may be greater than that required by the COMPASS computer code because of any or all of the following:
- placement of the initial random starting point (edge effects),
- odd shaped diagrams, and/or
- coverage concerns (see Attachment 6-1 to 6-33 for VSP sampling point locations) 2.1.17 Because this design is a conglomerate of multiple slab surfaces into multiple survey units, the sample point locations are not derived from a single starting point.
Measurement location details for the sample points are provided in the diagrams in Attachment 6.
2.1.18 Some sampling points may need to be adjusted to accommodate obstructions within the survey area. Contact the SR coordinator to report any difficulties encountered when laying out systematic grid sampling points.
2.1.19 Because of the unusual arrangement of this survey area, with multiple disjointed slabs that do not correspond directly to single grids, the drawings in Attachment 6 are intended to be as close as practicable to as-left conditions. However, if actual layout is different from that shown, review with the cognizant SR coordinator, finish the survey if practicable, and mark up the drawings to indicate actual layout.
2.1.20 When an obstruction is encountered that will not allow collection of a sample, contact the cognizant SR coordinatorfor permission to delete the sampling point.
NOTE If remediation actions are taken as a result of this survey, this survey design must be revised or re-written entirely.
2.2 Measure concrete fixed point and elevated areas(s) IAW SNEC procedure E900-IMP-4520.04 sec 4.3.3 (Reference 3.2) and the following.
2.2.1 Clearly mark, identify and document all sample locations.
2.3.1 Second phase scan any location that is above the action level cited in Table 3.
2.3.2 Investigation of APs may require surface and sub-surface samples per the LTP section 5.5.3.4.5 (Reference 3.5).

4.2 Reference background data from offsite at the Williamsburg station were used as the initial estimate of variability. These results are shown on Attachment 8-1 and in Reference 3.15.
Additional variance data that is used to assess sampling requirements is derived from the survey, Reference 3.7.
4.3 The MARSSIM Sign Test (Reference 3.12) will be applicable for this survey design. No background subtraction will be performed under this criteria during the DQA phase.
4.4 The required points chosen by COMPASS are located on the survey map for the survey unit by the Visual Sample Plan (VSP) computer code (Reference 3.4).
4.5 Reference 3.5 and 3.6 were used as guidance during the survey design development phase.
4.6 Background for the 43-68B detector has been measured in the area, and ranges from about 250 to 300 cpm with averages of slightly less than 300 cpm (Reference 3.7). These recent survey result averages are used as the basis for the MDCscan.
4.7 The determination of the physical extent of this area is based on the drawing Reference 3.8 and a thorough walkdown I measurement of the survey unit.
4.8 Remediation History:
4.8.1 OL1 is an open land area. Portions contained the original SNEC site facility and the Saxton Steam Generating Station. Extensive remediation has occurred in the survey area.
The SNEC Radwaste building (RWDF), Control and Auxiliary (C&A) building, Containment Vessel (CV), the SSGS, various buried pipe tunnels and underground tanks were all removed to grade or below. The residual portions of the buildings have been previously surveyed and the release surveys have been accepted.
SNEC CALCULATION SHEET Calculation Number Revision Number Page Number E900-05-015 0 Page 8 of 11 Subject OL1 Paved and Misc. concrete surfaces MA8, PF1, DB5, DBI - Survey Design 4.8.2 The SSGS was backfilled when it was permanently shut down. Subsequently, residual licensed activity was found using core bores. The SSGS backfill was removed and surveyed through an automated conveyor system. Additional concrete surfaces in the SSGS basement were remediated and then the scanned backfill was replaced following survey.
4.8.3 The underground tank excavation was backfilled after the tanks were removed early in the project. This backfill was removed and scanned using a automated conveyor scanning system and is currently stored for re-use.
4.8.4 The barrel bunker was removed as part of the remediation process.
4.8.5 Underground drainage, sewerage systems and surface soils have been removed.
4.8.6 Some pavement was remediated during the building removal phase.
4.9 This survey design uses Cs-137 as a surrogate for all SNEC facility related radionuclides in the survey unit. The effective DCGLw is the Cs-137 DCGLw from the SNEC LTP (28000 dpm/1OOcm 2) adjusted (lowered) to compensate for the presence (or potential presence) of other SNEC related radionuclides (Reference 3.9). In addition, an administrative limit (75%) has been set that further lowers the permissible Cs-137 concentration to an effective surrogate DCGLw for this survey area.
The sample database used to determine the effective radionuclide mix for the OL1 area has been drawn from samples that were assayed at off-site laboratories. This nuclide mix is copied from Reference 3.15.
The GFPC detector scan MDC calculation is determined based on a 10 cm/sec scan rate, a 1.38 index of sensitivity (95% correct detection probability and 60% false positive) and a detector sensitivity (Et) of 23.9% cpmldpm for Cs-137. The expected range of background values varies from about 250 cpm to about 300 cpm.
4.10 The survey unit described in this survey design was inspected after remediation efforts were shown effective. A copy of the specific portion of the SNEC facility post-remediation inspection report (Reference 3.11) applicable to this design is included as Attachment 9-1.
4.11 No special area characteristics including any additional residual radioactivity (not previously noted during characterization) have been identified in this survey area.
4.12 The decision error for this survey design is 0.05 for the a value and 0.1 for the p value.
4.13 "Special measurements" (as described in the SNEC LTP, Reference 3.5) are included in this survey design. Section 5.5.3.4.5 discusses pavement surveys. This survey design is consistent with the LTP.
4.14 No additional sampling will be performed lAW this survey design beyond that described herein.
4.15 SNEC site radionuclides and their individual DCGLw values are listed on Exhibit I of this calculation based on Table 5-1 in Reference 3.5.
4.16 The survey design checklist is listed in Exhibit 2.
4.17 Area factors are shown as part of COMPASS output (see Attachment 7-1) and are based on the Cs-1 37 area factors from the SNEC LTP.
