SNEC CALCULATION SHEET Calculation Number Revsion Number Page Number E900-05-019 0 Page 2 of 8 Subject First Energy - Penelec Site NE Open Land Area OL4 - Survey Design 1.0 PURPOSE 1.1 The purpose of this calculation is to develop a survey design for the Saxton Nuclear Experimental Corporation 'First Energy-Penelec Site NE Open Land Area" OL4 areas that are located northeast of the SNEC facility site.' The area (0L4) is approximately 4800 square meters, and is a Class 1 survey'area. Because'the survey area exceeds the 2000 square meter limitation in Table 5-5 of the SNEC LTP (Reference 5.5) for maximum class 1 open land survey unit area, this survey area is subdivided into four survey units:
1.1.1 0L4-1, which consists of the 11 grids (1100 sq meters) between pins AZI17 and BC121.
1.1.2 0L4-2, which consists of the 11 grids (1100 sq meters) between pins BC117 and BE123 1.1.3 014-3, which consists of the 12 grids (1200 sq meters) between pins BE117 and BH121 1.1.4 OL4-4, which consists of the 14 grids (1400 sq meters) between pins BF117 and B1112 2.0
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. The US NRC has reviewed and concurred with the methodology used to derive these values. See Attachment 2-1 and 2-2.
Table 1, DCGLw Values I Volumetric DCGLw(pCIg-Cs-137) l 6.46 (4.8 A.L.)
NOTE: A.L. is the ste Administrative Umit (75% of effective DCGLw).
2.1 Survey Design 2.1.1 Scanning of soil (and.fill materials) shall be perfonmed using a 2" D by 2" Nal detector with a Cs-137 window setting (Reference 3.1). The window will straddle the Cs-137 662 keV full energy peak width (see typical calibration information on Attachment 3-1).
2.1.2 The instrument conversion factor/efficiency shall not be less than that assumed on Attachment 4-1 as 205.6 cp'muRlh - Cs4137.
2.1.3 Other instruments of the type specified in Section 2.1.1 above maybe used during the final status survey (FSS), but must demonstrate detection efficiencies at or above the value listed in Section 2.1.2 above.

SNEC CALCULATION SHEET Calculation Number Revision Number Page Number E900-05-019 0 Page 3 of 8 Subject First Energy - Penelec Site NE Open Land Area OL4 - Survey Design 2.1.4 The action level specified is based on the MDCscan. This' is adequate since the MDCscan is expected to be less than the DCGLw times the area factor.
2.1.5 If'a count rate greater than the action level of Table 2 is encountered during the scanning process:
2.1.5.1 Stop the scan process and locate the boundaries of the elevated area.
2.1.5.2 Mark the extent and peak count rate of the elevated area with stakes or other appropriate marking methods.
2.1.5.3 Continue scanning the remainder of the survey unit 2.1.5.4 Sample the elevated areass)' lAW SNEC procedure E900-IMP-4520.04 (Reference 3.2), and Section 2.2 of this document following assessment and evaluation for investigation sampling.
2.1.6 Class I soil should be scanned using a serpentine pattern that is -0.5 meters wide.
2.1.7 This is a class .1 survey area. All accessible surfaces are required to be scanned.
See Attachment 1-1 for grid layout for the four survey units.
2.1.8 Areas that cannot be accessed should be clearly noted along with the reason for not completing the scan in that area.
2.1.9 The minimum number of soil sampling points indicated by the COMPASS computer program (Reference 3.3) is 11'for each of the four survey units (see COMPASS output on Attachment 7-1 to 7-5).
2.1.9.1 Sampling depth should be lAW Section 2.2.
2.1.9.2 The MDCscan (soil) 'exceeds the effective administrative DCGLw Cs.137. (6.2 pCilg MDCscan @300cpm bkg > 4.8 pCig AL) but given the area factor for the assumed 1 meter squared elevated area (28.7 AF)'and for the' effective
.sample area (-3.5 AF), the scan MDC meets MARSSIM requirements.
2.1.10 VSP (Reference 3.4) is used to plot all sampling points on the included diagrams.
The actual number of random'start systemrtically 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 6-8 for VSP sampling point locations) 2.1.11 The starting points for physically locating sample sites in the survey unit are based on measurements from site grid pins as indicated on the diagrams, Attachment 6-1, 6-3,, 6-6, and'6-7. Soil sampling points are positioned using coordinates developed from these markers and are listed on Attachments 6-2, 6-4, 6-6, and 6-8.
2.1.12 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.-
SNEC CALCULATION SHEET Calculation Number Revision Number Page Number E900-05-01 9 l 0 Page 4 of 8 Subject First Energy - Penelec Site NE Open Land Area OL4 - Survey DesIgn 2.1.13 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 rewritten entirely.
2.2 Sample random points and elevated areas(s) lAW SNEC procedure E900-IMP-4520.04 (Reference 3.2) and the following.
NOTE Since the site surface dose model is 1 meter in depth, samples representative of the entire one meter thick dose model layer must be collected to satisfy the sampling requirements of Section 2.1.5 (of this document). This should be done by obtaining a well mixed sample of an entire 1 meter deep core. Section 4.2.3, 4.2.6 or 4.2.7 of site procedure E900-IMP-4520.04 are applicable when satisfying Section 2.1.5. Sampling due to an instrument alarm condition should also be of the entire 1 meter of soil/material.
2.2.1 Clearly mark, identify and document all sample locations.
2.2.2 Sample any location that is above the action level cited in Table 2 based on subsequent investigation instructions.
2.2.3 Maintain chain-of custody requirements on all design fixed point and action level samples (Reference 3.13).

4.2 The most recent scoping and post-remediation.soil'samples from this area (data obtained from Reference 3.14) are used as the initial estimate'of variability. These results are shown on Attachment 8-1. The grid locations where these' samples were taken are shown on Attachment 1-1.
4.3 The MARSSIM Sign Test (Reference 3.11) will be applicable' for this survey design. No background subtraction will be performed under this criteria during the DQA phase.
4.4 The required number of fixed survey points as determined by COMPASS are then 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 has been measured in the area, and is typically <300 cpm (Reference 3.7).
4.7 The determination of the physical extent of this area is based'on the drawing Reference 3.8.
4.8 Remediation History OL4 is an open land area. It has historically~contained activity greater than the DCGLw (e.g.
see Attachment 2-1) which has been excavated in several campaigns 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 CsI 37 DCGLw from the SNEC LTP (6.6 pCVg) adjusted (lowered) to compensate for the presence .(or potential presence) of other SNEC related radionuclides. 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.
4.10 The sample database used to determine the effective radionuclide mix for the OL4 area has been drawn from samples that 'were 'assayed at. off-site laboratories. This includes a specific sample result obtained in 2004 from the' OL4 survey'area (grid BF118) and is shown on Attachment 2-1 and 2-2. Review of.the data shows several radionuclides were not positively identified at any, significant concentration. These radionuclides have been removed from the data set and are' not considered further as any minor contribution is accounted 'for by the 'administrative, reduction 'of the surrogate DCGLw to 75% of the surrogate DCGLw based on' the 'identified nudlide ratios.: Radionuclides remaining include Cs-137, Co-60, Sr-90, Pu238, and Pu-239. Additionally,'the data shows Cs-137 to be the predominant radioactive contaminant (based 'on activity) found in the area.
I SNEC CALCULATION SHEET Calculation Number Revision Number Page Number E900-05-019 0 Page 6 of 8 Subject First Energy - Penelec Site NE Open Land Area OL4 - Survey Design The undecayed set of sample results were input to the spreadsheet titled "Effective DCGL Calculator for Cs-1 37' (Reference 3.9) to determine the effective volumetric DCGLw values for the OL4 area. The output of this spreadsheet is'shown on Attachment 2-2.
The Nal detector scan'MDC calculation is determined based on a 25 cm/sec scan rate, a 1.38 index of sensitivity (95% correct detection probability and 60% false positive) and a detector sensitivity of 205.6 cpmluR/h for Cs-I37. Additionally, the'detection system incorporates a Cs-137 window that lowers sensitivity to background in the survey unit. The resulting range of background values varies but is typically <300 cpm (Reference 3.7).
4.11 The survey unit described in this survey design was inspected after remediation efforts were shown effective. A copy of the OL4 specific portion of the SNEC facility post-remediation inspection report (Reference 3.10) is included as Attachment 9-1.
4.12 No special area characteristics including any additional residual radioactivity (not previously noted during characterization) have been identified in this survey area.
4.13 The decision error for this survey design is 0.05 for the a value and 0.1 for the 1value.
4.14 No "Special measurements' (as described in the SNEC LTP sec 5.5.3.4) are included in this survey design.
4.15 No additional sampling will be performed IAW this survey design beyond that described I herein.
4.16 SNEC site radionuclides and their individual DCGLw values are listed on Exhibit I of this calculation, derived from Table 5-1 of Reference 3.5.
4.17 The survey design checklist is listed in Exhibit 2.
4.18 Area factors are shown as part of COMPASS output'(see Attachment 7-15) and are based on the Cs-137 area factors from Table 5-15 in the SNEC LTP (Reference 3.5).

Have all tools, non-permanent equipment, and material not needed to perform the FSS been removed? X r;. 5. Are the survey surfaces relatively free of loose debris (I.e.. dirt, concrete dust. metal filngs, etc.)? X
- 6. Are the survey surfazes retatiely free of rquids (i.e., water, moisture, oil, etc.)? X
- 7. Are the survey surfaces free or all paint, which has the potential to shield radiation? X
- 8. Have the Surface Measurement TestAreas (SwrA) been established? (Referto Exbit 2for Instructions.) X
- 9. Have the Surface Measurement Test Areas (SMTA) data been collected? (Refrto Eibit 2 fr instrucons.) X I, 10. Are the survey surfaces easily accessible? (No scaffolding, high reach, etc. isneeded to perform the FSS) X
- 11. Islghting adequate to perform the FSS? X 12 Isthe area Industrially safe to perform the FSS? (Evaluate potential fall &trip hazards, canfined spaces, etc.) X I.,

NOTE: If a No answer is cbtained above, the Inspector should Imimediately correct the problem or Initiate corrective actions through the responsible ste department as applicable. Document actions taken andlor justilications in the Comment? section below. Attach additional sheets as necessary.
Comments:
Response to Question 1: Survey unit has not had a final post-remediation survey performed. Additionally a planned re-grading of sone surfaces Will require follow-up scans and sampling to establish the radiological conditions prior to the performance of FSS.
