Description FSSICharacterization Engineer Survey Unit Release Record EP-HPT-104 HPT-104

1) Embedded Pipe (EP) Survey Unit HPT-104 meets the definition of embedded pipe for Plum Brook Reactor Facility (PBRF).
2) EP HPT-104 is a Class 1, Group 3.1 survey unit as per the PBRF Final Status Survey Plan (FSSP) and Technical Basis Document (TBD)-06-004.
3) Surveys in EP HPT-104 were performed using a scintillation detector optimized to measure gamma energies representative of Cs-137. Sample #EP 3-6 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 (IAW) the Babcock Services Incorporated (BSI)/LVS-002, Work Execution Package (WEP)05-006. Survey instructions described in this document constitute "Special Methods" and the survey design used in the acquisition of survey measurements.
5) Instrument efficiency determinations are developed in accordance with the BSI/L.VS-002, WEP 05-006, these determinations are appropriate for the types of radiation involved and the media being surveyed.
6) Survey documentation (see Attachment 2) indicates water up to 114' inch in depth inside some portions of the piping at the time of survey. This is deemed to have a negligible the impact on the pipe source efftciency because minimal attenuation occurs as a result of this depth of water over the range of gamma energies being measured.

1.1 The subject pipe system is the 4" floor drain system for the Hot Pipe Tunnel (HF'T).

The HPT floor drain system consists of one major header with multiple floor drain access points that tie into the header for the Fan House and ends in the sump located in the HPT. The purpose of this system is to convey water from the various floor drain openings on the -12 ft el. Of the HPT to a hot sump located on the -12 ft of the HPT.

FSS Design # EP HPT-6 1.2 EP HPT-104 consists of approximately 273 feet of piping.

2.0 Survey Design Information Survey Unit: HF'T-104 Revision # Original 2.1 EP HPT-104 was surveyed IAW Procedure #BSI/LVS-002.

Page 2 of 3 2.2 100'Yo of the 4" ID pipe was accessible for survey. The accessible 4" ID pipe was surveyed by static measurement at one foot increments, for a total of 273 survey measwments.

2.3 Surface area for the 4" ID piping is 973 cm2 for each foot of piping, corresponding to a total 4" ID piping surface area of 265,269 cm2(26.6 mZ) for the entire length of (273') of 4" piping.

3.0 Survey Unit Measurement Locations/Data 3.1 Pipe interior radiological survey forms are provided in Attachment 2 of this release record.

4.0 Survey Unit Investigations/Results 4.1 None 5.0 Data Assessment Results 5.1 Data assessment results are provided in the EPIBuried Pipe (E3P) 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 mremlyr 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 HPT-104 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.

FSS Design # EP HPT-r64 Revision # Original Page 3 of 3 Survey Unit: HF'T-104 5.5 Statistical Summary Table Statistical Parameter Minimum 6.0 Documentation of evaluations pertaining to compliance with the unrestricted use limit of 25 mremfyr and dose contributions from Embedded Pipe and radionuclides contributing 1W 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 HPT-104 to be less than 1 mremlyr. The dose contribution is estimated to be 0.005 mremlyr based on the average of the actual gross counts.

Description I

2) EP HPT-104 is a Class 1, Group 3.1 survey unit as per the PBRF Final Status Survey Plan (FSSP) and Technical Basis Document (TBD)-06-004.

EP-HPT-104

3) Surveys in EP HPT-104 were performed using a scintillation detector optimized to measure gamma energies representative of Cs-137. Sample #EP 3-6 from Survey Request (SR)-13 was referenced for this decision.

1 4) Survey Instructions for this survey unit are incorporated into and performed in HPT-104

1) Embedded Pipe (EP) Survey Unit HPT-104 meets the definition of embedded pipe for Plum Brook Reactor Facility (PBRF).

Revision #

I accordance with (LAW) the ~abcock Services ~ncobrated (BSI)/LVS-002, Work Execution Packane (WEP)05-006. Survev instructions described in this document constitute "Special ~'ethods" and thesurvey design used in the acquisition of survey measurements.

Original

5) Instrument efficiency determinations are developed in accordance with the BSIILVS-002, WEP 05-006, these determinations are appropriate for the types of radiation involved and the media being surveyed.
6) This supplemental survey was performed after the structural decontamination of the hot pipe tunnel. This effort resulted in inadvertant deposition of debris into the HPT 104 system, and suspected degradation of the piping integrity due to mechanical agitation of the concrete slab above the drain piping.

2.0 Survey Design Information 2.1 EP HPT-104 was surveyed IAW Procedure #BSI/LVS-002.

2.2 100% of the 4" ID pipe was accessible for survey. The accessible 4" ID pipe was surveyed by static measurement at one foot increments, for a total of 282 survey measurements.

2.3 Surface area for the 4" ID piping is 973 cm2 for each foot of piping, corresponding to a total 4 ID piping surface area of 274386 cm2 (27.4 m2) for the entire length of (282') of 4" piping.

2.4 The supplemental survey yielded 3.3% more surface area than the initial survey. Additional measurements were acquired betweenFD-1 to FD-2, FD-2 to ED-3, and FD-5 to FD4. These measurements were acquired in the vicinity of suspected perforations or observed breaks in the upper piping surface as noted in video inspections performed after the decommissioning activities referenced in Item 6) of the survey unit description. These additional measurements were acquired at the six inch interval between the 12 inch intervals delineated in BSVLVS-002. The supplemental survey yielded one additional measurement between FDI-A and the FD-1 header. This variance is within acceptable expectations for acquiring survey measurements, and incurs no impact to the survey units compliance with the release criterion.

3.0 Survey Unit Measurement Locations/Data 3.1 Pipe interior radiological survey forms are provided in Attachment 2 of this release record.

4.0 Survey Unit Investigations/Results 4.1 None 5.0 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 mredyr dose goal established in Table 3-3 of the FSSP.

1 FSS Design # EP HPT-T%l Revision # Original Page 3 of 3 I Survey Unit: HPT-104 1

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 HPT-104 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 Statistical Summary Table 6.0 Documentation of evaluations pertaining to compliance with the unrestricted use limit of 25 mrernlyr and dose contributions from Embedded Pipe and radionuclides contributing 10% in aggregate of the total dose fbr both structural scenarios and soils.

6.1 A review of the survey results has shown that the dose contribution for EP HPT-104 to be less than 1 mredyr. The dose contribution is estimated to be 0.005 mremlyr based on the average of the actual gross counts. This is equivalent to the contribution estimated for the initial survey.

SUMMARY

SUMMARY

Survey Unit Release Record

1) Based on video observations of broken and perforated piping as described in the Supplemental Survey Description for HPT 104, this survey unit has been assessed as a buried pipe for final reporting in compliance with the release criterion.

Design #

Survey Unit #(s)

2) DCGL's for the building reuse scenario are used to demonstrate compliance with the release criterion for this release record. The DCGL's for embedded pipe will not apply.
3) The Original Survey is used as the survey for compliance with the release criterion. This survey has a slightly higher mean activity value, with higher and more numerous maximum activity values than the Supplemental Survey. The Original Survey therefore yields the most conservative approach to determining acceptance with the release criterion.

EP-HPT-1 04

4) The nuclides of concern were selected based on a comparison of the PBRF-FSSP Attachment B, Table B-12, "DCGL's for Building Reuse Scenario", and TBD 06-004, Table 15, " Radionuclide Activity Profiles for All Piping Groupsy'.
5) Comparison of these tables produces the following nuclides of concern for HPT-104 (Group 3.1 pipe);

HPT-1 04 Revision #

a. Cs137, C060, Am241, Eu154, C14, Ni63, Sr90 and H3
6) The nuclides of concern were scaled to Cs137 and compared against the DCGL for Building Reuse as presented in Table B-12 from Item 2).

Original

7) Seven of the measurements from the Original Survey are greater than Unity for the building reuse scenario DCGL's.

Summary Page 1 of 2

8) The area factor of 40.2 was utilized for this survey unit, this is the minimum area factor listed in Table 3-5 of the PBRF FSSP. Interpolation of area factors below 40.2 is not delineated in NUREG 1505 or PBRF procedure CS-09, interpolation would yield an area factor < 40.2. Thus, use of 40.2 is a conservative approach when performing EMT and EMC assessments for embedded piping release records.
9) EMC Unity and EMT Unity assessments were performed on the complete Original Survey data set and are presented in Attachment 1. The survey unit passes FSS.
10) The Supplemental Survey measurements were assessed against the building reuse scenario DCGL's and are presented in Attachment 2. The statistical summary of these results are compared against the statistical summary for the Original Survey and presented in Attachment 1. The evaluation is the Supplemental Survey validates there is no change to the activity disposition of the Original Survey as a result of decommissioning activities described in the Supplemental Survey. The Supplemental Survey replicates the Original Survey within acceptable tolerances.

1 1) A graphical presentation of the activity disposition throughout HPT 104 for the Original and Supplemental Surveys (versus embedded pipe DCGL unity) is presented as.

12) Soil samples were acquired in the vicinity of the pipe break noted between FD-5 and FD-6, this break is in the piping header, approximately 4' east of the header drain to the HPT Sump. The samples were acquired by coring the concrete above the soil sample locations followed by removing the These samples showed less than MDA for soil nuclides of concern with the exception of two samples from the Core Bore identified as Hole 4. The two soil samples in closest proximity to the concrete floor above HPT 104 showed traces of Cs137 at 1% and 3% of unity, these trace amounts are consistent with Cs137 contamination of the soil fiom sources other than plant operations during the time of plant construction (-1 960). Graphic representations of the piping, core bores, and soil sample locations and soil sample results are presented in Attachment 4.
13) The evaluation of the worst case observed breach of HPT 104 (Item 1 1) assesses there is no evidence of activity migration into the surrounding soils fiom HPT 104. It is further assessed the breaches in the HPT 104 piping were fomented and aggravated by decommissioning activities, and not likely fiom plant operations. The opportunity for activity migration fiom plant operations to the surrounding soil is nil.
