Survey Unit Release Record Design # EP-ROLB- 102 Revision # Original Page 1 of 3 Survey Unit #(s) ROLB- 102

1) Embedded Pipe (EP) Survey Unit ROLB-102 meets the definition of embedded pipe for Plum Brook Reactor Facility (PBRF).

2) EP ROLB- 102 is a Class 1, Group 4.2 survey unit as per the PBRF Final Status Survey Plan (FSSP) and Technical Basis Document (TBD)-06-004.

3) Surveys in EP ROLB-102 were performed using a scintillation detector optimized to measure gamma energies representative of Cs-137. Sample #EP 4-3 from Survey Request (SR)-13 was referenced for this decision.

4) Survey Instructions for this survey unit are incorporated into and performed in accordance with (JAW) the Babcock Services Incorporated (BSI)/LVS-002, Work Execution Package (WEP)05-006. Survey instructions described in this Description document constitute "Special Methods7'and the survey design used in the acquisition of survey measurements.

5) Instrument efficiency determinations are developed in accordance with the BSULVS-002, WEP 05-006, these determinations are appropriate for the types of radiation involved and the media being surveyed.

FSS Design # EP ROLB-102 Revision # Original Page 2 of 3 Survey Unit: ROLB- 102 1.0 HistoryDescription 1.1 The subject pipe system is the floor drain system for the -15 ft elevation of the Reactor Office and Laboratory Building (ROLB). The purpose of this system is to convey water from the various floor drain openings to the ROLB sump located on the sump room on the -15 foot elevation of the ROLB.

1.2 EP ROLB-102 consists of approximately 343 feet of piping. The piping system includes 1.5", 3" and 4" ID piping.

Survey Design Information 2.1 EP ROLB-102 was surveyed IAW Procedure #BSI/LVS-002.

2.2 100% of the piping was accessible for survey. The accessible pipe was surveyed by static measurement at one foot increments, for a total of 343 survey measurements.

2.3 The total surface area for the piping system is approximately 288,580 cm2 (28.9 m2) for the entire length of (343') of piping.

Survey Unit Measurement LocationsData 3.1 Pipe interior radiological survey forms are provided in Attachment 2 of this release record.

Survey Unit Investigations/Results 4.1 None Data Assessment Results 5.1 Data assessment results are provided in the EPBuried Pipe (BP) Survey Report provided in Attachment 1.

5.2 All measurement results are less than the Derived Concentration Guideline Level (DCGL) for radionuclide specific EP that corresponds to the 1 rnrem/yr dose goal established in Table 3-3 of the FSSP.

5.3 When implementing the Unity Rule, provided in Section 3.6.3 of the FSSP, and applying the Nuclide Fraction (NF), provided in TBD-06-004, the survey unit that is constituted by EP ROLB-102 passes FSS.

5.4 Background was not subtracted from the survey measurements and the Elevated Measurement Comparison (EMC) was not employed for this survey unit.

5.5 Cs-137 is designated as the primary nuclide of concern for piping Group 4.2 per Technical Basis Document (TBD)-06-004, which would optimally lead to a survey design based on the direct measurement of Cs-137.

However, many of the survey measurements (all but the first five appearing in the spreadsheet) and the associated portion of dose assessment for ROLB 102 were calculated and appropriately scaled for

FSS Design # EP ROLB- 102 Revision # Original Page 3 of 3 Survey Unit: ROLB- 102 Piping Group 4.2 based on the direct measurement of (20-60. TBD-06-004 and the supporting sample analysis from Survey Request 13 were not approved or published at the time the ROLB 102 survey measurements were acquired.

5.6 Statistical Summary Table Statistical Parameter Minimum Documentation of evaluations pertaining to compliance with the unrestricted use limit of 25 mremlyr and dose contributions fkom Embedded Pipe and radionuclides contributing 10% in aggregate of the total dose for both structural scenarios and soils.

6.1 A review of the survey results has shown that the dose contribution for EP ROLB-102 to be less than 1 mredyr. The dose contribution is estimated to be 0.020 mremlyr based on the average of the actual gross counts.

DQA Check Sheet Design # EP ROLB-111 Revision # Original Survey Unit # EP ROLB-111 Preliminary Data Review' Answers to the following questions should be fully documented in the Survey Unit Yes No N/A Release Record

1. Have surveys been petformed in accordancewith survey instructions in the Survey Design? X

2. Is the instrumentation MDC for structure static measurements below the DCGLw for Class 1 and 2 X

survey units, or below 0.5 DCGLw for Class 3 survey units?

3. Is the instrumentation MDC for ernbeddedlburied piping static measurements below the DCGLw ? X

4. Was the instrumentation MDC for structure scan measurements, soil scan measurements, and embeddedlburied piping scan measurements below the DCGLw,or, if not, was the need for additional X static measurements or soil samples addressed in the survey design?

5. Was the instrumentation MDC for volumetric measurements and smear analysis < 10% DCGLw ? X

6. Were the MDCs and assumptions used to develop them appropriate for the instruments and techniques used to perform the survey3

7. Were the survey methods used to collect data proper for the types of radiation involved and for the X

media being surveyed?

8. Were "Special Methodsmfor data collection properly applied for the survey unit under review? X

9. Is the data set comprised of qualified measurement results collected in accordancewith the survey X

design, which accurately reflects the radiological status of the facility?

Graphical Data Review

1. Has a posting plot been created? X

2. Has a histogram (or other frequency plot) been created? X

3. Have other graphical data tools been created to assist in analyzing the data? X Data Analysis

1. Are all sample measurements below the DCGLw (Class 1 8 2), or 0.5 DCGLw (Class 3)? X

2. Is the mean of the sample data < DCGLw? X

3. If elevated areas have been identified by scans andlor sampling, is the average activity in each X

elevated area < DCGLEMC (Class I), < DCGLw (Class 2), or ~ 0 . 5 DCGLw (Class 3)?

4. Is the result of the Elevated MeasurementsTest < 1.0? X

5. Is the result of the statistical test (S+ for Sign Test or Wr for WRS Test) 2 the critical value? X Comments:
