1.0 PURPOSE 1.1 The purpose of this calculation is to provide the survey design guidance to be followed for conducting final status surveys (FSS) in the SSGS Discharge and Intake Tunnels. The Intake Tunnel consists of multiple parts: the Main Intake Tunnel and both the North and South Intake tunnels, which split off from the Main Tunnel. These latter tunnels are located under the SSGS footprint.
1.2 Shonka Research Associates (SRA) will conduct scan surveys using procedures reviewed and approved by SNEC. These procedures are attached as Appendices.

2.1.6 The minimum scan coverage for Class 1 areas will be 100%, Class 2 areas, 50%
and for Class 3 areas, 10-50%.
2.1.7 Scan speed will be set in accordance with SRA procedures and the SNEC MDCSC 2n value calculated for structure surfaces.
2.1.8 The surface DCGLvw for this design is determined to be 6174 dpm/100 cm 2 based on the attached spreadsheet calculation (Attachment 3). This value is the 75%
administrative limit of the calculated surrogate Cs-137 value (8233 dpm/100 cm2 ).
2.1.9 The surface area DCGLemc will use the Cs-137 surface area factor for a 1-M2 area equal to 11. This value is calculated to be 67,914 dpm/100 cm2 .
2.1.10 The MDCn value for this design that SRA must achieve is 3087 dpmli00 cm2.
2.1.11 The volumetric DCGLw for this design is determined to be 4.78 pCilq based on the attached spreadsheet calculation (Attachment 9). This value represents the 75% administrative limit of the calculated surrogate Cs-137 value (6.38 pCi/g).
2.1.12 Areas greater than the DCGLw must be identified, documented, marked, and bounded to include an area estimate.
2.1.13 Class 1 areas with surface deformations that cannot be surveyed by Shonka will be identified by marking or painting around the suspect area's perimeter.
2.1.14 Remediation is indicated when any area exceeds 3 x the DCGLw for any scan measurement or when the value for any area of -1 square meter is greater than the DCGL.,rC. Note: If additional remediation is performed the survey unit design is void.

4.2 SNEC LTP section 2.2.4.1.4 and Figure 2-18 provide a description of the SSGS Discharge Tunnel.
4.3 SNEC LTP section 2.2.4.1.7 and Figures 2-26 and 2-28 provide a description of the Main Intake Tunnels.
4.4 Remediation History The Discharge Tunnel was contaminated as a result of radioactive liquid effluent discharges from the SNEC Facility. Ground water and several inches of silt on the floor of this below grade structure have been removed to adequately survey this area for characterization and final release. Several piping sections have been removed as they were near or above initial DCGLs values. Inaddition the north wall opposite Seal Chamber
During operation of the SSGS, water was drawn from the Raystown Branch of the Juniata River. A dam was utilized to impound the river in the area of the intake structure, which included the Intake tunnel. The intake water system only provided intake of river water to the SSGS and no discharges to the river were made via this pathway. During freezing weather, warm water from the SSGS Discharge Tunnel was diverted and allowed to flow into the SSGS Intake Tunnel via a pathway that utilized the Spray Pond supply piping.
This configuration was established in order to prevent ice formation on the intake tunnel screen wash and filtration system components. This flow path, by use of discharge tunnel water, would have provided a mechanism for low-level radioactivity to enter the SSGS intake tunnel. In the SNEC LTP, Figures 2-25 and 2-28 show the SSGS Intake Tunnel in detail.

Subject Shonka Discharge and Intake Tunnels FSS Survey Designs Sediment and concrete core sampling was performed in the Intake Tunnel. Results of these samples are documented in the SNEC LTP. In summary a total of 174 sediment samples were taken throughout the Intake Tunnel. Of these, 142 samples showed only Cs-1 37 above MDC. The average Cs-137 value was 0.46 pCig and the highest, 1.8 pCi/g.
Concrete core bores were obtained throughout the tunnel, analyzed and found to be
<MDC.
4.5 This survey determines the effective DCGL, value for Cs-1 37 using the spreadsheet mix in Attachment 2. A 25% reduction to the effective DCGL was performed to address de-listed radionuclides. The SNEC facility has instituted an administrative limit of 75% for the allowable dose for all measurement results. The de-listed radionuclide dose is accounted for within the 75% administrative limit. The 75% administrative limit is then applied to the calculated Cs-137 limit, e.g. 0.75 x 8,233 dpm/l00 cm2 = 6174 dpm/100 cM2 .
4.6 The MDCSCan calculation is determined based on LTP section 5.5.2.5. The calculation consists of the following: 8,233 dpmI100 cm2 x 0.75 x 0.5 = 3,087 dpm1O00 cm2 .
4.7 Special measurements including gamma-ray spectroscopy are not included in this survey design.
4.8 Static and other survey measurements may be conducted as applicable after review of the SRA survey is completed. This design will be revised to incorporate these surveys as determined by the FSS group.
4.9 The survey design checklist is listed in Attachment 1.

4.4 Remediation History The Discharge Tunnel was contaminated as a result of radioactive liquid effluent discharges from the SNEC Facility. Ground water and several inches of silt on the floor of this below grade structure have been removed to adequately survey this area for characterization and final release. Several piping sections have been removed as they were near or above initial DCGLs values. In addition the north
E ms SNEC CALCULATION SHEET Calculation Number Revision Number Page Number E900-03-016 2 Page 5 of _16 Subject Shonka Discharge and Intake Tunnels FSS Survey Design wall opposite Seal Chamber #3 has been remediated (scabbled). In the SNEC LTP, Figure 2-18 shows this tunnel in detail.
During operation of the SSGS, water was drawn from the Raystown Branch of the Juniata River. A dam was utilized to impound the river in the area of the intake structure, which included the Intake tunnel. The intake water system only provided intake of river water to the SSGS and no discharges to the river were made via this pathway. During freezing weather, warm water from the SSGS Discharge Tunnel was diverted and allowed to flow into the SSGS Intake Tunnel via a pathway that utilized the Spray Pond supply piping. This configuration was established in order to prevent ice formation on the intake tunnel screen wash and filtration system components. This flow path, by use of discharge tunnel water, would have provided a mechanism for low-level radioactivity to enter the SSGS intake tunnel.
In the SNEC LTP, Figures 2-25 and 2-28 show the SSGS Intake Tunnel in detail.
Sediment and concrete core sampling was performed in the Intake Tunnel.
Results of these samples are documented in the SNEC LTP. In summary a total of 174 sediment samples were taken throughout the Intake Tunnel. Of these, 142 samples showed only Cs-1 37 above MDC. The average Cs-1 37 value was 0.46 pCi/g and the highest, 1.8 pCi/g. Concrete core bores were obtained throughout the tunnel, analyzed and found to be <MDC.
4.5 This survey determines the effective DCGLw values for Cs-137 using the mixes in Attachments 2 and 3. A 25% reduction to the effective DCGLW was performed to address de-listed radionuclides. The SNEC facility has instituted an administrative limit of 75% for the allowable dose for all measurement results. The de-listed radionuclide dose is accounted for within the 75% administrative limit. The 75%
administrative limit is then applied to the calculated Cs-1 37 limit, e.g. in the case of the Intake Tunnel 0.75 x 27,992 dpm/100 cm2 = 20.994 dpm/100 cm2 .
4.6 The MDCscan calculation is determined based on LTP section 5.5.2.5. See Calculations section below.
4.7 Special measurements including gamma-ray spectroscopy are not included in this survey design.
4.8 Static and other survey measurements may be conducted as applicable after review of the SRA survey is completed. Per LTP section 5.4.3 instrumentation used for scan measurements that are capable of providing data of sufficient quality as that provided by static measurements, can be used in place of static measurements. If the scan measurements are < 10% of the applicable DCGL then no static measurements are required. This design will be supplemented to incorporate additional surveys as determined by the FSS group.
4.9 The survey design checklist is listed in Attachment 1.

Purpose:
The purpose of this calculation is to determine a representative isotopic mix for the Intake Tunnel from available sample analyses. The effective surface area DCGLW is then determined from the mean percent of applicable samples.
Ill. Data Selection Logic Tables: The radionuclide selection logic and subsequent DCGL calculations are provided in eight (8) tables. These tables were developed using Microsoft Excel. Table explanation is as follows.
Table 1: Raw Data Listing - This table provides a list of Intake Tunnel sample analysis results from scoping, characterization, and pre/post remediation surveys. The samples consist of various soil and sediments that were taken in support of the aforementioned surveys. As applicable, a sample number, sample location/description, radionuclide concentration, analysis date and a footnote key designator are provided for each sample. The type of sample media is embedded in the sample number (e.g. soil is SL and sediment is SD). Positive nuclide concentrations are noted with yellow/shaded background fields while MDAs are denoted by the less than (<) symbol.
Per the key code column each line of data is selected or de-selected on the basis of the representativeness of the sample media to the final condition of the survey unit. Of the 9 samples listed in Table 1, only sample I was deselected. This sample was deselected because the laboratory analytical performance for this sample did not meet prescribed MDAs and more recent samples provided more accurate information.
Table 2: Reduced Listing - This table provides the best overall representation of data selected from Table 1. Positive results are denoted in a yellow/shaded background field while MDA values are in a white background. The less than (<) sign has been dropped from the MDA values to allow mathematical operations within the spreadsheet.
Table 3: Decayed Listing - This table provides the decayed values of nuclides selected in Table 2. Half-life values (days) are listed above each respective nuclide column. Samples are decayed to the date noted above Table 2 (e.g. January 15, 2004).
Table 4: Decayed Listing-MDAs Removed - This table provides the final list of sample data that will be used to determine the percent of individual radionuclides relevant to the sample mix for the Intake Tunnel area of the SNEC site. MDA values have been removed except for the Cs-137 MDA in sample 8. Since there was not a posibve value for Cs-137 in this sample the MDA was considered a representative Cs-1 37 concentration for this analysis result. This data point was then used to determine the Cs-1 37/H-3 ratio.
Table 5: Decayed Listing-MDAs Removed-Mean Percent of Total - This table provides the calculation methodology for determining the relative fractions of the total activity contributed by each radionuclide. From this information the mean, sigma, and mean % of total are calculated. The mean % of total activity is used to calculate the effective surface gross activity DCGLW in accordance with MARSSIM equation 4-4. In this case the mean percentages for H-3 and Cs-137 are 56.43% and 43.57% respectively. Note that the H-3 mean percents were averaged using only samples 7 & 8. This is because there is no positive data for samples 1 through 6. This results in the H-3 mean being higher, which is conservative. See Table 6.

Subject Shonka Discharge and Intake Tunnels FSS Survey Design A question can be asked as to whether samples 1-6 (all Cs-1 37) should be considered one mix and samples 7-8 (primarily H-3) should be considered a separate mix. However, this was not considered for the following reasons:
- 1. If considered separate mixes the worst-case mix percentage would be H-3 @98.5%
and Cs-1 37 @1.5% from sample 7. Using this mix the calculated surface DCGL in Table 6 would only be reduced by 2%. See Figure 1.
- 2. Samples 7-8 are from an inaccessible area that connects the western section of the Intake Tunnel to the eastern part under the SSGS. This area would have been exposed to the same isotopic mix. These samples were taken during well drilling operations. The drawing for this area is described in Figure 2-28 in the SNEC License Termination Plan, Revision 3.
Therefore, a decision was made to average the results from samples 7-8 with the remaining samples to provide a best representative mix for this area.

Subject Shonka Discharge and Intake Tunnels FSS Survey Design IV. Summary - Since the Intake Tunnel is a concrete structure the release limit is based on the surface area DCGLW. Using the data selection logic tables above, the calculated gross activity DCGLW for surface area is 64,245 dpml100 cm2 as shown in Table 6. This value would be reduced by 25% to 48,184 dpm/100 cm2 as part of SNEC's requirement to apply an administrative limit for additional conservatism. This value is then multiplied by 0.4357 to correct for the Cs-137 fraction in the mix. Finally, the Cs-137 DCGLw would be 20,994 dDm/100 cm2, which would be used In the survey unit design to determine the instrument scan set points.

Subject Shonka Discharge and Intake Tunnels FSS Survey Design Attachment 3 DCGL Calculation Logic-Discharge Tunnel Survey Unit: SNEC Discharge Tunnel
- 11.
Description:
The purpose of this calculation is to determine a representative isotopic mix for the Discharge Tunnel from available sample analyses. The effective surface area and volumetric DCGLws are then determined from the mean percent of applicable samples.
IlI. Data Selection Logic Tables: The radionuclide selection logic and subsequent DCGL calculations are provided in seven (7) tables. These tables were developed using Microsoft Excel spreadsheet software. Table explanation is as follows.
Table 1: Data Listing - This table, which has been extracted from a larger database, provides a list of the most representative Discharge Tunnel sample analyses. These results are from scoping, characterization, and pre/post remediation surveys. The samples consist of various sediments, scrapings and concrete cores that were taken in support of the aforementioned surveys. As applicable, a sample number, sample location/description, radionuclide concentration, analysis date are provided for each sample. Positive nuclide concentrations are noted with yellow/shaded background fields while MDAs are noted in the gray shaded fields.
Table 2: Decayed Listing - This table provides the best overall representation of data selected and decayed from Table 1. In Table 1 half-life values (days) are listed above each respective nuclide column. Samples are decayed to the date noted above Table 1 (e.g. January 15, 2004). Positive results are denoted in a yellow background field while MDA values are in a gray background.
Table 3: Decayed Listing of Positive Nuclides & MDAs Removed- This table provides the decayed values of positive nuclides selected in Table 2. In addition MDA values have been removed from this table.
Table 4: Mean Percent of Total for Positive Nuclides - This table provides the calculation methodology for determining the relative fractions of the total activity contributed by each radionuclide. From this information the mean, sigma, and mean % of total are calculated. The mean % of total values is used to calculate the surface gross activity DCGLW per MARSSIM equation 4-4. See Table 6. Note that the Co-60 mean percents were averaged using only samples 1 & 2. In addition, the mean percents calculated from sample 2 for Am-241, Pu-238, Pu-239 and Ni-63 were not averaged throughout the spreadsheet since there was only one sample where these respective nuclides were positive. This results in higher 'mean percent of total' values in the mix, which are conservative.
Table 5: Ratio to Cs-1 37 for Positive Nuclides - This table provides the calculation methodology for determining the surrogate ratio to Cs-137 for each radionuclide. From this information the mean, sigma, and mean % of total are calculated. The mean % of total values is used to calculate the volumetric DCGLW per MARSSIM equation 1-14. See Table 7. Note that the Co-60 ratios were averaged using only samples 1 & 2. In addition, the ratios calculated from sample 2 for Am-241, Pu-238, Pu-239 and Ni-63 were not averaged throughout the spreadsheet since there was only one sample where these respective nuclides were positive. This results in higher 'mean percent of total" values in the mix, which are conservative.
Note: From Tables 4 and 5 only the "mean % of total" values are used as input to the "Effective DCGL Calculation Spreadsheet" as illustrated in Tables 6 and 7.

Subject Shonka Discharge and Intake Tunnels FSS Survey Design Table 6: Effective DCGL Calculator for Cs-137 (dpm/100 cmA2) - This table provides the surface gross activity DCGLW calculation results from data inputted from Table 4.
Table 7: Effective DCGL Calculator for Cs-137 (in pCilg) - This table provides the surrogate volumetric modified Cs-137 DCGLW calculation results from data inputted from Table 5.
IV. Summary - Since the Discharge Tunnel is a concrete structure the release limit is primarily based on the surface area DCGLW. However, a small portion of the Discharge Tunnel ceiling Class 1 area has volumetric contamination. Using the above data selection logic tables the calculated gross activity DCGLW for surface area is 8,968 dpm/100 cm2 . The Cs-137 volumetric DCGLW is 6.52 pCi/g. These values would be reduced by 25% as part of SNEC's requirement to apply an administrative limit as required by the License Termination Plan (LTP).

- 4. General Information The incremental encoder provides a method of determining the distance traveled by the SCM. The encoder turns and generates TTL level pulses at regular intervals. A calibration factor in pulses per inch allows the SCM to determine distance by number of pulses. This calibration factor could be determined by dividing the pulses per rotation by the circumference of the wheeL To reduce the impact of measurement error this procedure determines the calibration factor by rolling the cart a known distance and dividing by the pulses received by the counter card in the SCM to get a pulselin factor.

SCM PROCEDURE 005, REVS DATE. 7117103 PAGE 3 OF 9 TITLE: REQUIREMENTS FOR COMPLETION OF A SURVEY USING THE SCM
- 1. Purpose This procedure details tile requirements for completion of a survey using the SC.IM.
- 2. Scope and Limitations This procedure applies to version 2.0 or later of the SCMI process softvare.
ITEM DESCRIPTION The Surface Contamination Monitor is a mobile platform SCNI containing detectors, support electronics. and data logger used tor conducting radiological survevs.
Survev Information Management System - SINIS is flexible and comprehensive interfacing software for the SRA SCM. SLMS processes the SCNI instrument data with a sophisticated data parser, integrated spreadsheet, and powerful special functions such SIMS as spatial data filters. S'IMS provides the most flexible reporting system available for printing survey records or complete stand-alone survey reports. SLNIS contains all the tools needed to meanin!6ullv communicate between the SCM\I and the data analysis team.
Position Sensitive Proportional Counter - This is a radiation detector that is capable of establishing where alongfite detector-a pulse is sensed (the system is described in NUREG/C-R-6450).
PSPC The detectors are similar in efficiency to other counters, but have backgrounds associated with small area detectors (5cm x 5cm).
This results in improved sensitivity, due to low backgound, and specific identification of the location of the radioactivity. The PSPCs may be fabricated in any length.
Source Response Check - Determines if the system is operating the same from day-to-day.
PBC Performance Based Check - Determines the system efficiency and performance.
SCM PROCEDURE 005, REVS DATE: 7117103 PAGE 4 OF 9 TITLE: REQUIREMENTS FOR COMPLETION OF A SURVEY USING THE SCM 4 General Information 4.1. Rolling Mode Check the wheel encoder upon arrival on site per "SCM Procedure 001 '. Check the PSPC per "SCMi Procedure 007".
The Project Manager establishes the survey speed based on the isotopes of concern and the desired sensitivities set forth bv the client. The SCM svstem is capable of concurrent alpha, beta and gamma surveys.
An SCMY survey uses the concept ol'survey strips. SINIS reassembles the strips to provide complete documentation of a survey without requiring any manual transfer of data. The operator makes a crude sk etch of the area and indicates the direction and start point of each strip. Record the filename of the survev on the sketch and. if available, note a reference coordinate for one of the comers of the survey area. The surface does not need to be pre-gidded. Mark the surface into survey lanes using a chalk line or other markings. Tile wheel encoder enables tracking of distance down each lane.
Markings onl the detector hiousing allow the operator to align the detector to the lane.
Each lane is twice as wide as the detector. Typical survey lanes arc about 12 feet wide.
Start the SCMI software if it is not alreadv active and enter the survey parameters:
- Survey Name (Filename),
- Room ID, and
- Equipment ID.
Use the speed indicator on the computer display to adjusted to the proper Survey speed.
After establishing the speed. disengaged the motor and position the SCIViith the frint of the first PSPC at least 10 cm before the start of the first survey lane. Start the motor and begin logging data as the leading edge of the first PSPC enters the survey lane by pressing the <Record> button. The motor maintains a constant speed, while the operator guides the cart down the lane unless using the fly-by-wire or autonomous carts. Upon reaching the end of the lane, press the <Stop> button on the SCMI screen and optionally disengaged the motor. Position the cart to record the next lane. Repeat this process until completing the survey.
Change the filename and optionally the Room ID)to prepare the instrument for the next survey area. The display provides information during the survey process, such as, survey name, strip number, distance traveled in strip, target speed and current speed, alarm set points, and detector data. Two different display types for the detector data exist in the SC\M process softwvare. For a pixilated image of the flux from the floor with color corresponding to intensity, select the visualization screen. For a more

REQUIREMENTS FOR COMPLETION OF A SURVEY USING THe SCM traditional feel, select the bar graph screen that has rows corresponding to roughly 4-inch bins across the detector. The system also provides visual and audible alarms to the user to indicate problems with operating parameters such as speed. The SCMN logs data to the disk drive from anv combination ofthe detectors while the <Record> kev is active. This permits reassembly of the data in the SIMS application.
4.2. Corner Mode Use the comer detector operated in a data-logging mode to survey areas not accessible with the SCNI attached to the motor driven cart. The output of comer mode is compatible with SlIMS. The comer detector is a PSPC operated in a similar fashion to the SCM rolling survey, but with a fixed time internal for each detector placement and data acquisition. The Project Manager establishes the time interval to provide a sensitivitv that is consistent with that established for the rolling mode.
Measure out 10 cm strips along the surface being measured. Start the SCM softwvare if it is not alreadv active and enter the survey parameters: Survey Name (Filename),
Room ID. and Equipment [D. Position the detector between the first set of marks and press <Record> button in the SCNI process software. At the end of the preset time interval, the system stops recording. Move the detector into the next position. and record the next strip. Repeat this process until completing the survey.

- 1. Purpose This procedure details the requirements for baseline source response checks (SRC),
daily SRCs and Performance Based Checks (PBC) of any PSPC detector configuration installed on the SClM.
- 2. Scope and Limitations This procedure applies to version 2.0 or later of the SCMI process softvare.
ITEM DESCRIPTION The Surfacc Contamination Monitor is a mobile platform SCMI containing detectors. support electronics, and data logger used for conducting radiological survevs.
Sur-ey Information Management System - SIMNS is flexible and comprehensive interfacing sollwarc for the SRA SCMI. SlIMS processes the SCMI instrument data with a sophisticated data parser, integrated spreadsheet. and powerful special functions such SINIS as spatial data filters. SPAS provides the most flexible reporting system available for printing survey records or complete stand-alone survey reports. SINIS contains all the tools needed to meaningfully communicate between the SCNI and the data analysis team.
Position Sensitive Proportional Counter - This is a raiition detector that is capable of establishing where along the detector a pulse is sensed (the system is described in NUREG/CR-6450).
The detectors are similar in efficiency to other counters, but have PSPC backgrounds associated with small area detectors (5cm x 5cm).
This results in improved sensitivity, due to low background, and specific identification of the location of the radioactivity. The PSPCs may be fabricated in any length.
Source Response Check - Determines if the system is operating the SRC same from day-to-day.
Performance Based Check - Determines the system efficiency and PBC performance.
SCM PROCEDURE 007, REV7 DATE. 7/17103 PAGE 4 OF 12 TITLE: SOURCE RESPONSE CHECK AND PERF#RMANCE BASED CHECK OF ANY PSPC DETECTOR CONFIGURATION INSTALLED ON THE SCM
- 4. General Information Normal operation of the SCMI with a PSPC requires daily SRCs to assure that the PSPC is performing within acceptable limits. Perform this procedure at the beginning and end of each shift for each detector in use. Compare the results to the results of the dailv SRC to the baseline SRC for this project. Use the initial daily SRC for a project as the baseline SRC.
Any time a system parameter changes. take a new baseline SRC for comparison with proceeding dayvs. Examples ofaltered parameters would be:
- 1. Change in high voltage.
- 2. Calibration source changed.
Perform Performance Based Checks (PBC) frequently through out the course of the survev. The PBCs establish the system performance during the survey and are the basis for the detector efficiency. Moreover, the PBCs affect the reported surface activity output by SIDS.

SCM PROCEDURE 007, REV7 DATE 7117103 PAGES OF12 TITLE: SOURCE RESPONSE CHECK AND PERFORMANCE BASED CHECK 01 ANY PSPC DETECTOR CONFIGURATION INSTALLED ON THE SCM
- 7. Procedure 7.1. Source Response Check Measurement.
7.1.1. If this is a baseline SRC, use the form in Appendix A, "Baseline Source Response Check Form"; othervise, use the form in Appendix B, "Daily Source Response Check Form". Use this procedure for all detectors regardless of configuration. Perform all source response checks with the detector and source stationary. If desired, use a source holder so that the placement of the source to the detector is repeatable.
7.1.2. Enter the Energy/Position analvzer by following these steps:
7.1.2.1. Press tile <Setup> button.
7.1.2.2. Press the <Supervisor> button.
7.1.2.3. Press the <Calibrations> button.
7.1.2.4. Press the <Detector Position> button.
7.1.2.5. Press the <Use Position Analvzcr> button.
- 7. 1.3. Mlake sure that there are no sources under the detector.
- 7. 1.4. Start Acquisition by pressing the <Acquire> button.
7.1.5. When the 1-minute timed acquisition ends, integrate the entire spectrum and record the measured background for the entire spectrum.
- 7. 1.6. Record the measured background on the appropriate forr in the column labeled "Total Counts" and the row labeled "Background for Entire Array".
7.1.7. Place calibration source under the center of the detector or in contact with mylar or protective screen. When the SCM is setup for rolling mode, it is often quicker to place the source on the ground and roll the cart to position the source under the detector. When surveying in corner mode, it is often quicker to turn the PSPC over and place the source directly on the mylar or protective screen. In any case, assure that the source to detector geometry is the same as when the baseline SRC was taken.
7.1.8. Start Acquisition by pressing the <Acquire> button.
7.1.9. When the 1-minute count is complete, record the count with calibration source on the data table in the appropriate row for the given detector of the appropriate form in the column labeled "Total Counts".
SCM PROCEDURE 007, REV7 DATE. 7117103 PAGE 6 OF 12 TITLE. SOURCE RESPONSE CHECK AND PERFORMANCE BASED CHECK OF ANY PSPC DETECTOR CONFIGURATION INSTALLED ON THE SCM 7.1.10. Repeat Steps 7.1.7-7.1.9 for each detector in the PSPC array.
7.2. Source Response Check Evaluation 7.2.1. For each detector, subtract the recorded background entered in the data table in the row labeled "Background for Entire Array" from the recorded "Total Counts" for each detector. Enter the result in the block "Total Background Subtracted Counts".
Note: If this procedure is being done to establish a baseline, it is now complete.
If this is a comnp(triisoni to buselinc. proceed to step 7.2.
7.2.2. Copy values in the column labeled "Total Background Subtracted Counts" from the baseline form for each detector onto the form "Daily Source Response Check Form" in the column labeled "Total Baseline Background Subtracted Counts" provided in Appendix B.
7.'.3. For each detector perform the calculation shown in Equation I and record the value in the block "Percent Difference from Baseline Measurement" on the form in Appendix B.

7.3.1. Perform periodic PBCs throughout the course of the survey. Perform PBCs at the beginning of the shift, at least once per 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> of surveying, and at the completion of each shift.
7.3.2. Perform all PBCs using the same source. The source used for efficiency determination is acceptable but not required to be used.
7.3.3. Obtain PBCs in the same performance manner as normal surveys, i.e.
SCM speed and detector height, or timer setting and height for corner detectors.
7.3.4. Establish a survey file name for the Perforrmance Based Checks. See SCM Procedure 01I for file naming conventions.
ACM PROCEDURE 007, REV7 DATE. 7117103 PAGE 7 OF 12 TITLE: SOURCE RESPONSE CHECK AND PERFORMANCE BASED CHECK OF ANY PSPC DETECTOR CONFIGURATION INSTALLED ON THE SCM 7.3.5. Place the source on the floor and perform a survey of the area, operating the SCIM in accordance with SRA Procedure 005. For rolling surveys, center the source along the PSPC axis 1.0 m from the leading edge of the first detector before rolling the cart over the source. For corner surveys place source on detector mylar or protective screen.
7.3.6. For comer surveys, press the <Record> button and wait until acquisition is complete. For rolling surveys press record. then start motor. Continue strip until last detector is 1.0 m past the source.
7.3.7. Repeat the survey3 times for each PBC.
7.3.S. Record the time, filename, strip numbers, and the source used in the logbook or survev form.
7.3.9. Evaluation of the PBCs for the duration of the survey occurs in the survey report issued upon completion of the survey.
S.1.2. Daily SRCs are acceptable if all "Percent Difference from Baseline Measurement" values are less than 20%O. If a system fails to meet the acceptance criteria, all survey data taken since the last acceptable PBC or SRC will be rejected. Also, the system should be removed from service until the failure is resolved.
8.2. PBCs :
3.2.1. Use SINIS software to process the PBC data files. Establish a control chart indicating the mean and "2-sigma" and "3-sigma" values.
Evaluate subsequent PBCs against the "2-sigma" and "3-sigma" criteria and for indications of adverse trends. If more than I of the 3 measurements obtained during a PBC is greater than the "2-sigma" or if any measurement is greater than "3-sigma", the PBC fails. Surveys bounded by a failed PBC are considered invalid. If a system fails to meet the acceptance criteria, all survey data taken since the last acceptable PBC or SRC will be rejected. Also, the system should be removed from service until the failure is resolved.

- 7. Procedure 7.1. Pre Deployment Preparation
- 7. 1.1. Designate the Project Manager.
- 7. 1.2. Choose a project name. SIMS uses this name to catalogs documents in the SINIS directory structure. The project name should be a single word of no more than S characters.
- 7. 1.3. The Pro ject Mlanager creates a directory on the SIMS workstation using the Project Name.
- 7. 1.3. 1. The Pro ject Manager maintains control of the documents in these directories during the course of the survey; however, control transfers to the Office Mslanager upon completion of the survey.
- 7. 1.3.2. Any of the directories may include sub-directories to organize the stored data. For example, on large surveys a directory may contain multiple sub-directories for separate sections of the survey. The naming convention should aid in identification of the particular areas. For example, use directory names such as exterior, interior, bldgI, elevl, etc.
If using a Survey Identification Code, then use that code as the directory name. Typically, the "_QRaw" and "_.,SRaw" directories do not have sub-directories. Create at a minimum the following sub-directories under the Project name directory as shown in Table 3. Any references this procedure makes to the directories in Table 3 includes the sub-directories created under them.
