1 Survey Unit Release Record I 1 Design # I EP 1.11 1 Revision # I Original 1 Page 1 of 4 I Survey Unit #(s) Description

1) Embedded Pipe (EP) Survey Unit 1.11 meets the definition of embedded pipe for Plum Brook Reactor Facility (PBRF).

2) EP 1.1 1 is a Class 1, Group 1 survey unit as per the PBRF Final Status Survey Plan (FSSP) and Technical Basis Document (TBD)-06-004.

3) Surveys in EP 1 .I 1 were performed using a scintillation detector optimized to measure beta energies >85 keV (IS0 7503-1 Table3, Tc99). This energy is lower than the beta energy for Co60 (96 keV, IS0 7503-1 Table 3), assuring the nuclide of concern for DCGL is assessed during data acquisition.

1 4) Survey Instructions for this survey unit are incorporated into and performed in accordance with (IAW) the Babcock Services 1nLrporated (BSI)/LVS-003, Work Execution Package (WEP)05-006. Survev instructions described in this -. document constitute "Special ~kthods" and thesurvey design used in the acquisition of survey measurements.

5) Instnunent efficiency determinations are developed in accordance with the BSIILVS-003, WEP 05-006, these determinations are appropriate for the types of radiation involved and the media being surveyed.

FSSICharacterization Engineer FSSICharacterization Manager Approval Signatures Date: I I FSS Design # EP 1.11 Revision # Original Page 2 of 4 Survey Unit: 1.11 1.0 History/Description 1.1 The subject pipe is the 24" hot leg for the PCW system. The function of this piping was to convey heated water away from the reactor core.

1.2 EP 1.11 consists of 24" diameter piping that is approximately 146 feet in length. 2.0 Survey Design Information 2.1 EP 1.11 was surveyed IAW Procedure #BSI/LVS-003.

2.2 106 feet of the 24" pipe was accessible for survey. The inaccessible piping includes elbows (5) and the three feet of piping between the 0' elevation and the -3' elevation in the PPH Room

4. The elbows and their approaches are inaccessible to the pipecrawler. The 3' in PPH Room 4 is released to the structural DCGL and will not be grouted. The survey for this piping will be accomplished as part of the structural release survey in PPH Room

4. 2.3 100% of the accessible piping was scanned.

2.4 16 survey locations were selected by a random number generator for static measurements. The locations were assigned as eight from the vessel access point and eight from the PPH Room 4 access point. Five of these locations were in the inaccessible elbows. At each accessible location four static measurements were acquired IAW BSI/LVS-003 for a total of 44 static measurements (Att. 1A).

2.5 The surface area for the 24" piping is 5837 cm 2 for each foot of piping, corresponding to a piping surface area of 852202 cm 2 (85 m 2) for the 146 feet of embedded pipe 24" 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 FSS Design # EP 1.11 Revision # Original Page 3 of 4 Survey Unit: 1.11 5.0 Data Assessment Results 5.1 Data assessment results are provided in the EP/Buried Pipe (BP) Survey Report provided in Attachment 1A & 1B.

5.2 This survey unit was assessed for compliance with the release criterion attributing all activity derived dose as a 100% Co60 nuclide distribution. This is the most conservative DCGL for the facility.

5.3 Scan measurements require a 90 second scan time to survey each section of accessible 24"piping at

< 1inch/second. The documented gross cpm measurement for each scan is the highest, instantaneous, cpm count rate

observed during the 90 second scan. The derived activity from these scan measurements is the most conserva tive quantity for that section of assessed piping. This conservatism is replicated when determining compliance with the DCGL releas e criterion. (BSI/LVS 003, WEP 05-000-6). 5.4 When implementing the Unity Rule, provided in Section 3.6.3 of the FSSP, the survey unit that is constituted by EP 1.11 passes FSS.

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

survey unit.

5.6 Based upon the results of the final survey measurements including the scan survey of the upper piping boundary in the Primary Pump House, it is reasonable to conclude that the fina l survey of the accessible portions of this pipe system is appropriate to demonstrate the radi ological condition of the entire pipe. Survey Unit EP 1.11 demonstrates compliance with the inaccessible piping acceptance criteria of Section 7.5 of the PBRF FSSP.

5.7 The physical configuration of this surv ey unit consists of a 24" pipe in a conformal steel support box whic h is surrounded by a concrete sarcophagus of at least two feet in th ickness for the entire length of the piping bounded by the survey unit. There is no access into the survey unit from any adjacent survey units, and the steel support box is inaccessible to personnel.

5.8 It is presented that this piping consti tutes a single, contiguous and distinct survey unit unto itself. This survey units' dose contribution is <2 mr/yr and is significantly within a release criterion of 25mr/yr. The dose contribution of this survey unit does not impact adjacent structural survey units.

6.1 A review of the survey results has shown that the dose contribution for EP 1.11 to be less than 2 mrem/yr. The dose contribution is estimated to be 1.009 mrem/yr based on the average of the actual gross counts measured.
