00L-09-0 1 is open land area consisting of an approximately I, 102 sq m surface area and at one time contained an accumulation of soil and construction debris as well as discarded components that were generated over the life of the plant. During decommissioning, RSS concrete rubble, as well as material >DCGL were stockpiled within the boundaries of Survey Unit 01. 00L-09-0 1 contains the footprint/remnants of Pile #24 - consisting of RCA soil and debris as well as RSS (Reactor Support Structures) concrete rubble. Due to the potential impact of the RSSIRCA debris being transported and stored on a portion of 00L Survey Unit 01 is designated as Class 1. The problem as defined by this survey plan is to demonstrate that the years of plant operation and stockpiling of RSSIRCA soils and concrete rubble did not result in an accumulation of plant- related radioactivity that exceeds the release criteria.

00L-09-02 is open land area consisting of an approximately 1,123 sq m surface area and at one time contained an accumulation of soil and construction debris as well as discarded components that were generated over the life of the plant. During decommissioning, RSS concrete rubble, as well as material >DCGL were stockpiled within the boundaries of Survey Unit 02. 00L-09-02 contains the footprintlremnants of Pile #24 - consisting of RCA soil and debris as well as RSS (Reactor Support Structures) concrete rubble. Due to the potential impact of the RSSIRCA debris being transported and stored on a portion of 00L Survey Unit 02 is designated as Class 1. The problem as defined by this survey plan is to demonstrate that the years of plant operation and stockpiling of RSS/RCA soils and concrete rubble did not result in an accumulation of plant-related radioactivity that exceeds the release criteria.

CLASS 1 El CLASS 2 CLASS 3 DATA QUALITY OBJECTIVES (DQO)

--- A 1.0 State the aroblem:

00L-09-0 1 is open land area consisting of an approximately I, 102 sq m surface area and at one time contained an accumulation of soil and construction debris as well as discarded components that were generated over the life of the plant. During decommissioning, RSS concrete rubble, as well as material >DCGL were stockpiled within the boundaries of Survey Unit 01. 00L-09-0 1 contains the footprint/remnants of Pile #24 - consisting of RCA soil and debris as well as RSS (Reactor Support Structures) concrete rubble. Due to the potential impact of the RSSIRCA debris being transported and stored on a portion of 00L Survey Unit 01 is designated as Class 1. The problem as defined by this survey plan is to demonstrate that the years of plant operation and stockpiling of RSSIRCA soils and concrete rubble did not result in an accumulation of plant-related radioactivity that exceeds the release criteria.

The planning team for this effort consists of the FSS Project Manager, FSS Radiological Engineer, FSS Field Supervisor, and FSS Technicians. The FSS Radiological Engineer will make primary decisions with the concurrence of the FSS Project Manager.

2.0 Identify the decision:

Does residual plant-related radioactivity, if present in the survey unit, exceed the release criteria? Alternative actions may include no action, investigation, resurvey, remediation and reclassification.

3.0 Identify the inuuts to the decision:

CLASS 1 CLASS 2 CLASS 3 DATA QUALITY OBJECTIVES (DQO) 1.0 State the problem:

00L-09-02 is open land area consisting of an approximately 1,123 sq m surface area and at one time contained an accumulation of soil and construction debris as well as discarded components that were generated over the life of the plant. During decommissioning, RSS concrete rubble, as well as material >DCGL were stockpiled within the boundaries of Survey Unit 02. 00L-09-02 contains the footprintlremnants of Pile #24 - consisting of RCA soil and debris as well as RSS (Reactor Support Structures) concrete rubble. Due to the potential impact of the RSSIRCA debris being transported and stored on a portion of 00L Survey Unit 02 is designated as Class 1. The problem as defined by this survey plan is to demonstrate that the years of plant operation and stockpiling of RSS/RCA soils and concrete rubble did not result in an accumulation of plant-related radioactivity that exceeds the release criteria.

The planning team for this effort consists of the FSS Project Manager, FSS Radiological Engineer, FSS Field Supervisor, and FSS Technicians. The FSS Radiological Engineer will make primary decisions with the concurrence of the FSS Project Manager.

2.0 Identify the decision:

Does residual plant-related radioactivity, if present in the survey unit, exceed the release criteria? Alternative actions may include no action, investigation, resurvey, remediation and reclassification.

1.7 Classification

CLASS l CLASS 2 CLASS 3 El DATA QUALITY OBJECTIVES (DQO) 1.0 State the problem:

00L-09-03 is open land area consisting of an approximately 5,217 sq m surface area, including the roadway and buffer zones for the Class 1 survey areas 00L-09-01/00L-09-02. This survey unit is located at the site of the Southeastern Construction Fill Area and includes the haul roads to the SCFA.

During decommissioning, soil, rock and concrete rubble were transported within the boundaries of Survey Unit 03. The problem as defined by this survey plan is to demonstrate that the years of plant operation did not result in an accumulation of plant-related radioactivity that exceeds the release criteria.

The planning team for this effort consists of the FSS Project Manager, FSS Radiological Engineer, FSS Field Supervisor, and FSS Technicians. The FSS Radiological Engineer will make primary decisions with the concurrence of the FSS Project Manager.

2.0 Identifv the decision:

Does residual plant-related radioactivity, if present in the survey unit, exceed the release criteria?

Alternative actions may include no action, investigation, resurvey, remediation and reclassification.

3.0 Identifv the inputs to the decision:

Sample media: Soil Types of measurements: Soil samples and gamma scans Radionuclides-ofconcern:

Characterization data for the 00L-09 area was taken using TSOCS from 5/23/06 through 5130106 -this is the most recent data for the survey area and will be used in this plan. A total of 89 measurements were taken using ISOCS, resulting in one positive measurement for co60 and eight positive measurements for CS"~. All other plant-related radionuclides were <MDA. The results from the characterization data are summarized below:

~ s(8 detects)

' ~ ~ is present in 9% of the characterization samples. The maximum value was <5% of the 8.73-mrem/y ~ s DCGL ' ~of 3.0

~ pCi1g while the average value was 4%.

co60 (1 detect) co60 is present in <2% of the characterization samples. The maximum value was 4 1 % of the 8.73-mremly co60 DCGL of 1.4 pCi/g. Based on only one detect out of 89 locations, Co-60 is not considered to be a nuclide of concern.

FSS Sample data from adjacent survey units 00L-09-01, 00L-09-02 and 00L-09-05 was alsc reviewed. The FSS data showed lower average and maximum values than the characterization data wit1 both Co-60 and Cs-137 being detected in <3% of all samples at levels <4% of respective DCGL's.

Applicable DCGL: The DCGLs applied under this survey plan correspond to annual doses of 8.73 m r e d y (the 10-mrernly DCGL adjusted for the dose contributions from sub-surface concrete structures and tritium in ground water).

DPF-8856.1 Page 6 of 9

4. Sample Analysis:

I Gamma analysis will be performed on all soil samples. If any of the gamma analyses show that an investigation level has been exceeded an investigation survey will be conducted at that sample location per Specific Instruction #7.

YNPS Chemistry will analyze 00L-09-03-001-F through 00L-09-03-015-F and 00L-09-03-016-F-B through 00L-09-03-019-F-£3for gamma-emitting nuclides.

YNPS Chemistry will analyze 00L-09-03-013-F-S for gamma-emitting nuclides prior to being sent R

to the off-site laboratory. This sample will be analyzed for gamma-emitting nuclides and HTD at the off-site laboratory. Ensure that the lid to the I-liter Marinelli container is secured and sealed with electrical tape to prevent loss of moisture during shipping.

YNPS Chemistry will analyze 00L-09-03-012-F as a sample recount. The recounted sample will possess the naming convention 00L-09-03-0 12-F-RC.

On-site gamma analysis of the FSS samples shall achieve the MDC values stated in the DQO section of this plan. The MDCs will be communicated to the laboratory using an attachment to the Chain-of-Custody form.

5. ISOCS Assays:

I Collect ISOCS assays in accordance with DP-887 I to provide 10% scan coverage of the survey unit.

ISOCS assays are designated as 00L-09-03-xxx-F-G where xxx corresponds to the 3-digit location 1I indicated on survey map "ISOCS Scans # 1".

QC checks shall be performed at daily in accordance with DP-8869 and DP-8871. Resolve flags encountered prior to survey.

ISOCS assays to be performed with 90' collimator at 2m unless otherwise directed by the FSS Engineer. Make note on the daily survey journal (DPF-8856.2) if other geometries are used.

Remove standing water prior to performance of ISOCS assays. Contact the FSS Engineer for directions if conditions are such that standing water cannot be removed.

Make note of any conditions within the ISOCS field of view that may affect analysis of ISOCS assay data such as mud, concrete, etc.

Designate additional assay locations in continuing sequence from the last number assigned to an FSS I

measurement. Record detailed information about additional assay locations on the daily survey journal.

If the results on any ISOCS assay exceed the investigation level (any positive indication of for plant-related radionuclides), investigate that assay as directed in Specific Instruction # 8.

6. SPA-3 Scans 11 FSS Technicians will perform scans by moving the SPA3 detector at a speed 5 0.25 m/s, keeping the probe at a distance of less than 3 inches from the ground surface, and following a serpentine pattern that includes at least 3 passes across each square meter. When scanning and walking, a slow pace (i.e., 1 step per second) shall be used. Scanning will be performed in the rate-meter mode with the audible feature on. Surveyors will listen for upscale readings, to which they will respond by slowing down or stopping the probe to distinguish between random fluctuations in the background and greater than background readings. Location(s) where detectable-above-background scan readings are found will be investigated.

DPF-8856. I Page 7 of 9

7. Soil Sample Investigations:

R If any soil samples exceed investigation criteria (0.5 x DCGL,), an investigation will be performed.

If it becomes necessary to investigate soil samples, this FSSP will be revised to include direction.

8. ISOCS Investigations If the results of an ISOCS assay exceed an investigation level, perform a first level investigation as follows:

m: Detailed descriptions of investigation actions shall be recorded in the daily survey journal (DPF-8856.2).

I Perform ISOCS scan measurements at each investigation location as follows:

I o Perform ISOCS scans at Im height with 90' collimation o Perform ISOCS scans at 5 locations within a 4-m grid centered over the original ISOCS scan location - One centered over the original scan location and one in each corner of the grid centered at 1.4 m from the center of the grid. ISOCS Scan Investigation Map # 1 shows the proper positioning for ISOCS investigation scans.

o Identify investigation ISOCS scans using the convention: NOL-03-02-xxx-F-G-I, where xxx indicates the next sequential location number starting with 300 (i.e. the first investigation ISOCS scan performed will be NOL-03-02-300-F-G-I).

o Indicate any observations in the daily survey journal. Locations of ISOCS scans should be recorded by use of GPS when available.

The FSSE will review investigation ISOCS scans and will direct performance of SPA-3 scans as set forth in the following steps. Note: The FSSE may direct performance of additional investigation surveys or terminate steps by use of memo that will be inserted in the survey package file.

Scan the ISOCS area of evaluation footprint with a SPA-3 in rate-meter mode moving the detector at a speed of 0.25m or less per second, keeping the probe at a distance of approximately 3" from the surface and following a serpentine path that includes at least 3 passes across each square meter.

Survey Unit Name: SCFA Surrounds FSSP NO.: YNPS-FSSP-00L-09-04-00 Detection Limits: For direct measurements and sample analyses, Minimum Detectable Concentrations (MDCs) less than 10% of the DCGL are prefered , while iMDCs up to 50% of the DCGL are acceptable. See Attachment 2 for MDC Table.

MDC CfDCGL): The accompanying MDCRMDC table in Attachment 1 provides MDC values, as a fraction of DCGL, for various background levels.

MD CR(suweyor) .. The accompanying MDCRIMDC table in Attachment 1 provides MDCR values for various background levels.

Background Measurements: No reference area (background) measurements are required, the Sign Test will be used.

Release criteria DCGL based on: 8.73 rndyr for Soil. See Attachment 2 for radionuclide specific breakdown of DCGLs.

4.0 Define the boundaries of the survey:

Define the spatial and temporal boundaries that will be covered by the decision statement so data can be easily interpreted.

Temporal boundaries: The data are used to reflect the condition of radionuclides leaching into the ground water over a period of 1,000 years. The survey may be performed under appropriate weather conditions (as defined by instrument tolerance and personnel safety) on any shift of work.

Spatial Boundaries: YNPS has been divided into multiple survey areas and units with relatively homogeneous characteristics based on information collected during the years of facility operation, the HSA, and post remediation activities. The area of interest has been named 00L-09, and the survey unit is 04. The medium of interest is described as Soil. The radiological characteristics of this unit classify it as a Class 3 area.

Which has no restrictions as a surface area limit. The total surface area is 7186.7 m2, which is in compliance with the no restrictions limit. The maximum length is 124m, and the maximum width is 93.3m. Soil is surveyed to a depth of 15 cm.

See included GPS coordinates and maps that demonstrate the measurement locations, the survey unit boundaries and unit relationship to site.

Detailed description of unit: 00L-09-04 is open land area consisting of an approximately 7,186.7 sq m surface area forming a buffer zone for the Class 1 survey units 00L-09-01 and 00L-09-05.

Survey unit 00L-09-04 shares a boundary with 00L-09-03. Survey unit 04 is not part of the RCA and there are no sub-surface systems that traverse or connect within the survey unit. There are no plant-related structures present in this survey unit. Due to low potential impact - 00L-09-04 meets the criteria for a Class 3 survey area.

5.0 Develop a decision rule:

Define the parameter of interest, specify action levels, and the DCGL.

Investigation Levels: If an investigation level below is exceeded, then perform an investigation survey.

Direct measurements: > 50% DCGLw Scan measurements: Detectable over background Parameter of interest: If there are no investigation issues, and the the residual radioactivity in 00L-09-04 systematic samples is less than the DCGLw then the survey unit is in compliance with the release criterion (8.73 mriyr).

Critical Value: If the average concentration is less than DCGLw, the sum of fractions is less than 1, and less than 4 of the 15 samples are above the DCGLw, the Survey Units passes.

CLASS 1 O CLASS 2 CLASS 3 DATA QUALITY OBJECTIVES (DQO) 1.0 State the problem:

00L-09-05 is open land area consisting of an approximately 735.6 sq m surface area, and at one time contained an accumulation of soil and construction debris. During decommissioning, soil, rock and concrete rubble were stockpiled within the boundaries of Survey Unit 05. 00L-09-05 contains the footprint of Piles #15 11152 - consisting of soil, rock and concrete rubble debris from excavations of the East Storm Drain, Mt. Herdon, the Service Building and the Alleyway (all within the RCA). Due to the potential impact of the RCA excavation material being transported and stored on a portion of 00L Survey Unit 05 is designated as a Class 1 area. The problem as defined by this survey plan is to demonstrate that the years of plant operation and stockpiling of soil, rock and concrete rubble did not result in an accumulation of plant-related radioactivity that exceeds the release criteria.

The planning team for this effort consists of the FSS Project Manager, FSS Radiological Engineer, FSS Field Supervisor, and FSS Technicians. The FSS Radiological Engineer will make primary decisions with the concurrence of the FSS Project Manager.

2.0 Identify the decision:

Does residual plant-related radioactivity, if present in the survey unit, exceed the release criteria?

Alternative actions may include no action, investigation, resurvey, remediation and reclassification.

Upon review of the FSS data collected under this survey plan:

(a) Sf all the sample data show that the soil concentrations of LTP-listed nuclides are below the 8.73 mredyear DCGLs and the sum of fractions of LTP-listed nuclides are below unity, then reject the null hypothesis (i.e., Survey Unit 00L-09-05 meets the release criteria).

(b) lfthe investigation levels are exceeded, then perform an investigation survey.

(c) If the average concentration of any LTP-listed nuclide exceeds its respective DCGL, or the average sum of fractions of LTP-listed nuclides exceeds unity, then accept the null hypothesis (i.e., Survey Unit 00L-09-05 fails to meet the release criteria).

If the results on any ISOCS assay exceed an investigation level, investigate the area within the ISOCS area of evaluation (2.8m radius - 24.6m2 area for 180"-lm) for that assay as directed in Specific Instruction # 7.

Remove standing water prior to performance of ISOCS assays. Contact the FSS Engineer for directions if conditions are such that standing water cannot be removed.

6. If the results of any FSS sample (statistical andlor biased points) analysis exceed an investigation level, perform a first level investigation as follows:

m: Detailed descriptions of investigation actions shall be recorded in the daily survey journal (DPF-8856.2).

Review ISOCS data for assays in which the sample requiring investigation may have been in the field of view.

Scan a Im radius footprint around the sample location with a SPA3 in rate-meter mode moving the detector at a speed of 0.25m or less per second, keeping the probe at a distance of approximately 3" from the surface and following a serpentine path that includes at least 3 passes across each square meter. The area of scan should be increased as necessary to bound any areas of elevated activity identified.

Mark the boundaries around any detected elevated areas in the soil and identify the boundaries on a survey map. Measure the total area of each outlined area in square centimeters.

Mark the location of the highest identified activity for each of the elevated areas in the soil and on the survey map.

Rev. 1 Supplement to 00L-09-05 FSS Plan D O 0 Step 7.0 Optimize Design (add to end of section)

Note: This supplement provides specific instructions for performance of investigation surveys of ISOCS scan measurements. ISOCS scan measurements that exceed the investigation criteria (stated in Section 3.0 of this plan) or other measurements selected by the FSSE will be investigated. Due to the survey unit proximity to the ISFSI, SPA-3 measurements are greatly influenced by radiation associated with stored fuel. It is preferable to use ISOCS in a collimated geometry in an attempt to reduce the area requiring SPA-3 scans.

S~ecificInstructions S t e 7~ (add after Note. before first bullet)

ISOCS scan locations to be investigated are 00L-09-05-127-F-G and 00L-09-05-137-F-G.

Perform ISOCS scan measurements at each investigation location as follows:

o Perform ISOCS investigation scans at l m height with 90° collimation.

o Perform ISOCS scans at 5 locations within a 4-m grid centered over the original ISOCS scan location - One centered over the original scan location and one in each comer of the grid centered at 1.4 m from the center of the grid. ISOCS Scan Investigation Map #1 shows the proper positioning for ISOCS investigation scans.

o Identify investigation ISOCS scans using the convention: 00L-09-05-xxx-F-(3-1, where the xxx indicates the next sequential location number starting with 300 (i.e. the first investigation ISOCS scan performed will be 00L-09-05-300-F-G-I).

o Indicate any observations in the daily survey journal. Location of ISOCS scans should be recorded by use of GPS when available.

o The FSSE will review investigation ISOCS scans and will direct performance of SPA-3 scans.

o Note: The FSSE may direct performance of additional investigation surveys or terminate steps by use of memo(s) that will be inserted in the survey package file.
