SUMMARY

Revision History Revision 1 Revision 1 of this Equivalent Change Package (ECP) has been created per FCR 60089561-0410 for the complete ECP.

Revision 0 Revision 0 was issued as the Advance Work Authorization (AWA) ECP to complete core bores for pn.

I.(a.) Description of Change (Problem that the Change was intended to address):

The No. 12 and 14 Auxiliary Feedwater (AF) headers of the Unit 1 Salem Station Auxiliary Feedwater (AF) System buried piping have been excavated and inspected in accordance with the buried piping program. Guided wave inspections revealed general corrosion of the external surface of the coated carbon steel piping. After excavation, the piping was ultrasonic tested (UT) to determine the extent of the corrosion. It has been determined that this piping needs to be replaced due to below code allowable minimum wall thickness. The corroded piping delivered the required amount of water to the steam generators at the start of the Salem 1R20 outage.

I.(b.) Design Margin Impact (provide brief description. Identify Design Analyses impacted):

Calculation S-C-AF-MDC-1 789, Salem Auxiliary Feedwater Thermal Hydraulic Flow Model, is impacted by this replacement due to the use of elbows and mitered pipe joints instead of 5D pipe bends. However, the revision to this calculation will be part of DCP 80101382 since that configuration change reroutes sections of the No. 12 and 14 headers directly upstream of this replacement. SAP operation 80101382-0020 tracks the revision of this calculation.

Calculation 6S0-1882 (AD S02), Qualification of Safety-Related Buried Commodities for Tornado Missile and Seismic Evaluation, is impacted by this replacement due to the use a of controllable low-strength material (CLSM), i.e., flowable fill, instead of compacted soil for backfill of the excavated area. Replacing the excavated soil with CLSM would increase the pipe stress due to soil overburden since the CLSM is denser than the soil. However, since DCP 80101382 reroutes the AF piping in the Fuel Transfer Tube Area above ground, the maximum buried depth of the Unit 1 AF piping is reduced to 5'-2 1/4" (6' is conservatively used in this calculation). This decreases the pipe stress on the Unit 1 buried AF piping due to soil overburden. The conclusion of this calculation that the pipe stress due to soil overburden is negligible remains valid. Also, the replacement of the 5D bends with mitered pipe joints and cut elbows does not impact this calculation since the stress intensification factor is not considered because the pipe is constrained by the CLSM, as stated on page 93 of the calculation.

CHANGE NO: 80101381 REVISION NO.: 1 II. Scope of Change:

The scope of this Equivalent Change Package (ECP) is the in-kind replacement of the sections of the 4" diameter No. 12 (Line 1075) and 14 (Line 1053) Auxiliary Feedwater (AF) system headers that are routed underground outside containment from the Salem Unit 1 Fuel Transfer Tube Area to the Unit 1 Main Steam Outer Penetration Area. This piping has been determined to have wall thicknesses below the code allowable minimum wall thickness. For some sections of the piping in the replacement scope the wall thickness could not be measured using ultrasonic testing (e.g., at pipe supports and inside wall penetrations).

The scope of this piping replacement ECP includes the following:

  • Replacing the portion of the No. 12 and 14 AF headers that runs underground from the Unit 1 Fuel Transfer Tube Area to the Unit 1 Main Steam Outer Penetration Area.

" Coating all buried piping with Enecon CeramAlloy CL+AC.

" Reusing the existing pipe hangers and anchors. Pipe hangers and anchors may be modified in order to expedite the pipe coating process.

  • Replacing 5D bends within the piping replacement scope of this ECP with elbows and mitered pipe joints to expedite installation.
  • Repairing penetration seal W-19401-008 with alternate flanged boot seal.
  • Replacing exposed/damaged outer containment wall waterproof coating with Enecrete WS.

" Utilizing flowable fill in lieu of compacted soil backfill in repair trench.

  • Pipe hangers and anchors for the CA/SA lines utilizing the same steel as the Aux Feed lines may be modified in order to expedite the pipe coating / backfill process.

Due to the emergent nature of this ECP, final updates of non-Pl/P2 documents will be performed by revising the applicable ADs. SAP operation 80101381-0210 tracks this activity.

Ill. Screenings (a.) For Commercial Changes, was the screening criteria of CC-AA-103 Attachment F satisfied? YES EJ NO X N/A F]

[If Attachment F is not satisfied, another change type is required.]

This criteria is not satisfied; at a minimum question #5 is a "Yes" answer (the portion of the AF piping replaced by this ECP is Safety Related, Nuclear Class 3), thus a Commercial Change is not the appropriate Configuration Change type.

(b.) For Equivalent Changes, was the screening criteria of CC-AA-103 Attachment G satisfied? YES M NO F N/A F-1

[If Attachment G is not satisfied, another change type is required.]

This criteria is satisfied; all questions were answered "No." Thus an Equivalent Change is the appropriate type of Configuration Change to implement.

FORM 4 SOLUTION / TECHNICAL EVALUATION Section Design Change Attribute 4.1.4.1. IDENTIFY Basic SSC Functions Auxiliary Feedwater System (AF)

The AF System serves as an emergency backup for supplying feedwater to the secondary side of the steam generators at times when the Main Feedwater System is unavailable. The system is relied upon to prevent core damage and system over-pressurization in the event of accidents such as loss of normal feedwater or a secondary system pipe rupture and also .provides an alternate to the Main Feedwater System during startup, hot standby and plant cooldown conditions. The replacement piping installed by this ECP is identical in material and size and mimics the routing of the existing piping with the exception of elbows and mitered pipe joints and therefore has no impact on the AF system functions.

Penetration Seal W-19401-008 Penetration seal W-1 9401-008 ensures that water cannot enter the Main Steam Outer Penetration Area from the outside area where the piping is buried. This seal is repaired in accordance with procedure SH.MD-SP.FBR-0014 and VTD 311694. The penetration sleeve is damaged and cannot be replaced in-kind.

Containment Buildinq Wall Coatinq The containment building wall coating acts as a moisture barrier between the grade elevation soil and the buried portion of the containment wall. This coating was exposed as a result of the piping excavation and found to be in a degraded condition. This ECP applies an Enecon Enecrete WS (CICP 200-1948) waterproof coating to the containment building wall in the excavated area. See Section 4.1.38.

4.1.4.2. IDENTIFY Configuration Change safety classification.

Per Salem Piping Schedule SPS54E, the AF piping replaced by this ECP is Nuclear Class 3, thus this Configuration Change is classified as Important-to-Safety. This packages replaces the piping in kind.

Penetration Seal S1 FLB-W-1 9401-008 is non-safety related per SAP.

The containment structure is safety related (ref UFSAR Section 3.2).

4.1.4.3. IDENTIFY Seismic Classification of the SSC.

Per Salem Piping Schedule SPS54E, the AF piping replaced by this ECP is Seismic Class 1.

Penetration Seal S1 FLB-W-1 9401-008 is Seismic Class 2 per SAP.

The containment building is a Seismic Class 1 structure (ref. UFSAR 3.2)

CHANGE NO: 80101381 REVISION NO.: 1 Section Design Change Attribute 4.1.5. PROVIDE the performance requirements and design conditions of the SSC needed to evaluate the change from the existing to the modified systems, structures, or components.

Piping Replacement:

Per Salem Piping Specification S-C-MPOO-MGS-0001 Schedule SPS54E, the AF system piping is A106 Gr. B, sch. 80, seamless carbon steel, silicon killed (deoxidized with silicon prior to casting). The normal and maximum operating conditions of the portions of piping replaced by this ECP are as follows:

, O .perating C .ditions Normal Pressure (psig) 1195 Max. Pressure (psig) 1950 Normal Temperature (TF) 140 Max. Temperature (OF) 140 The replacement piping installed by this ECP is replaced in-kind and meets all requirements of S-C-MPOO-MGS-0001 Schedule SPS54E.

Penetration Seal W-19401-008:

Penetration seal W-19401-008 has been found to have a corroded sleeve and is in need of replacement. The original seal detail is shown on VTD 311694. The seal can not be repaired to the original detail due to the unavailability of the Biscoseal TC-28 (and its equivalent, TC-33) material used to seal around the sleeve and the penetration inside diameter. In lieu of the original seal detail, procedure SH.MD-SP.FBR-0014 Attachment 1 shall be used to fabricate a flanged boot seal. The new boot seal requires the use of at least four 1/4" Tapcon bolts with a minimum embedment of 1" and attaches to the wall in lieu of the inside diameter of the penetration.

Flowable Backfill Material:

After the piping replacement is completed, the piping will be reburied using a flowable fill material. This material is required to have a 28 day compressive strength of not greater than 125 psi. See Section 4.1.38 for details on the flowable fill material.

4.1.6. DETERMINE the design requirements necessary to facilitate periodic surveillance testing and acceptance testing that is necessary for the Configuration Change being considered.

The following acceptance testing is required on the AF system piping for this replacement:

" Perform Non-Destructive Evaluation (NDE) of welds in accordance with CC-AA-501, Welding/Brazing Manual.

  • Perform cleanliness verification of piping in accordance with NC.CH-AP.ZZ-0021(Q),

System Cleanliness Program.

  • ASME Section XI requires a system pressure test at normal operating pressure (NOP) and normal operating temperature (NOT). A system pressure test lAW SC.MD-GP.ZZ-0035(Q) may be performed in lieu of the in service leak test at NOP/NOT.

N/A 4.1.9. DETERMINE changes required to existing Design Analysis or new parameters that require new calculations or calculation revisions that are used to assess the acceptability of a system or a component function in meeting various physical requirements.

Calculation S-C-AF-MDC-1 789, Salem Auxiliary Feedwater Thermal Hydraulic Flow Model, is impacted by this replacement due to the use of elbows and mitered pipe joints instead of 5D pipe bends. However, the revision to this calculation will be part of DCP 80101382 since that configuration change reroutes sections of the No. 12 and 14 headers directly upstream of this replacement. SAP operation 80101382-0020 tracks the revision of this calculation.

Replacing the excavated soil with CLSM would increase the pipe stress due to soil overburden since the CLSM is denser than the soil. However, since DCP 80101382 reroutes the AF piping in the Fuel Transfer Tube Area above ground, the maximum buried depth of the Unit 1 AF piping is reduced to 5'-2 1/4" (6' is conservatively used in this calculation). This decreases the pipe stress on the Unit 1 buried AF piping due to soil overburden. The conclusion of this calculation that the pipe stress due to soil overburden is negligible remains valid. Also, the replacement of the 5D bends with mitered pipe joints and cut elbows does not impact this calculation since the stress intensification factor is not considered because the pipe is constrained by the CLSM, as stated on page 93 of the calculation.

CC-AA-1 02, Attachment 2 was reviewed for this CP and provided no "yes" answers. Therefore there are no Fire Protection and Appendix R requirements impacted by this modification.

4.1.13. DETERMINE any Material requirements, such as material grade, product form, compatibility with existing or other new materials, galvanic interaction between dissimilar metals, special welding material requirements, critical properties, performance characteristics, alternative materials as well as any Material Suitability requirements such as compatibility, electrical insulation properties, protective coating, corrosion resistance, mechanical insulation etc. necessary for the Configuration Change.

All material quantities and material masters required for implementation are provided in Form 7 of this change package.

Pipinq Material The piping materials used for replacement must comply with PSEG specification S-C-MPOO-MGS-0001 piping schedule SPS54 group E. The piping group reference is found on P&ID 205236 sht. 001.

The piping material designation is ASTM A106 Gr. B, seamless carbon steel. The piping is 4",

which is required to be schedule 80.

The fittings are 4" schedule 80 butt welded fittings. The fitting material designation required is ASTM A234 WPB.

Welded Joints Joints for the replacement must comply with PSEG specification S-C-MPOO-MGS-0001 piping schedule SPS54 group E.

All joints 2-1/2" and larger are to be butt welded.

CHANGE NO: 80101381 REVISION NO.: 1 Section Design Change Attribute Pipe Coating All buried piping must be coated PRIOR to reburial to prevent further piping corrosion. The coating types available for this application as well as vendor suggested prep methods are provided in this change package as SUP02. This coating has been used in various other systems such as service water at Hope Creek and Salem.

The CICPs for the available coating types are as follows:

CICP 200-1969 CICP 200-2046 Containment Wall Coating Prior to reburial of the piping, the containment wall should be coated with Enecrete WS. See SUP03 for product description and vendor suggested application methods. The CICP for Enecrete WS concrete sealant is 200-1948. See Section 4.1.38.

4.1.14. Determine environmental conditions and impacts.

There are no environmental conditions or impacts because the AF system piping replaced only holds demineralized water.

4.1.15. DETERMINE if Environmental Qualification (EQ) of equipment is affected. (Use Attachment 3 of CC-AA-1 02 to determine impact)

N/A 4.1.16. REVIEW the Operating Experience databases through the INPO Internet Site or equivalent in accordance with LS-AA-1 15:

An Operating Experience (OE) review/search was conducted including early NRC and INPO documents on buried and underground piping. The following applicable OEs have been found:

OE28063 - Corrosion Degradation of Flange Connections on Buried Pipe - San Onofre Unit 2 -

During excavation and unwrapping of a buried discharge pipe to perform ultrasonic (UT) examinations the flange, studs, and nuts for a flange at ground level were found to be extensively corroded. The affected flange couples a carbon steel elbow above ground with carbon steel piping for a below ground run. The flange connection was originally designed to be completely above ground, but the buildup of asphalt had buried the bottom flange.

OE1 0840 - Leaking Buried Steam Pipe - Alternate Supply to AFW Pump - Palisades - Buried piping which supplies steam to the turbine driver for AFW Pump, developed a through-wall leak, resulting in declaring the pump inoperable. The inspection of the pipe, once it was excavated, attributed the cause to externally originated general corrosion. The piping specification describes a protective coating which was to be applied to the pipe at the time of original installation. This protective coating has apparently deteriorated over the years, as there was little evidence of any intact protective coating on the pipe which was excavated for the repair.

Page 11 of 24 CC-AA-103-IO01, Rev 3

CHANGE NO: 80101381 REVISION NO.: 1 Section Design Change Attribute OE10250 - Underground Drisco Pipe Failure - Perry Unit 1 - Drisco pipe is used to provide non-safety related Instrument Air to the Service Water Pumphouse, the Emergency Service Water Pumphouse, and the Circulating Water Pumphouse. The lines are installed underground.

Past repairs involved replacement of only the leaking portions. The most recent activity involved complete replacement of both lines. The failed pipe exhibited severe pipe wall delamination, showing an outer wall, an inner wall and an annular region filled with granular material. The utility concluded that use of the DRISCO pipe in this air service application was acceptable.

Past inspections of failed pipe typically also showed evidence of mechanical damage near the leak. An additional contributing factor is that during initial installation, the pipe was not handled correctly causing external damage to the pipe wall. Over the course of time, about 15 years, the damaged areas give way to the delaminating causing through-wall leaks.

OE29621 - Standby Shutdown Facility - Auxiliary Service Water Buried Pipe Leak - Oconee Unit 2 - A through-wall pinhole leak in the Standby Shutdown Facility - Auxiliary Service Water buried (underground) piping was discovered as a result of fluctuating flow indications that are monitored as part of operator rounds. The flaw in this safety-related line was determined to be a hole rather than a crack. The hole diameter is less than the size which would challenge operability of the system based on system leakage rate, and will be monitored for growth. The apparent cause of the pinhole is external pitting corrosion due to local coating degradation.

The above OE reports all point to problems with the proper installation of the coating on buried piping. Therefore, holiday testing is specified in accordance with ASTM D 5162, Standard Practice for Discontinuity (Holiday) Testing of Nonconductive Protective Coating on Metallic Substrates, as part of the Form 5 testing.

4.1.17. DETERMINE if the configuration change may affect the existing Equipment Performance Information Exchange (EPIX) database.

Hydraulic Impact The AF piping is replaced in accordance with the material requirements in Salem Piping Schedule SPS54E. The replacement piping follows the same route as the existing piping, but the 5D bends are replaced by elbows and mitered pipe joints. A preliminary evaluation has determined that these changes have a negligible impact on the hydraulic resistance of the replaced section of piping.

Calculation S-C-AF-MDC-1 789, Salem Auxiliary Feedwater Thermal Hydraulic Flow Model, will be revised under DCP 80101382 since that configuration change reroutes sections of the No.

12 and 14 headers directly upstream of this replacement. SAP operation 80101382-0020 tracks the revision of this calculation.

Pipe Supports Note that supports 12AFWA-1I and 14AFWA-11 are anchors and are maintained as anchors (see Drawing 226129 Sh. 003). To facilitate coating of the piping and to expedite repairs, the supports can be cut and re-welded with similar steel (see SUP04). The configuration shown on SUP04 provides similar support. Since the piping is buried, the supports do not impact pipe stress analysis. The supports provide support during construction and back-filling of the soil.

The supports were originally designed and analyzed by calculations 267274F and G, reference drawing AF-11-3A sheet. 1. Calculation 267274F was voided and 267274G was revised to remove the analysis for these supports based on calculation 6S0-1882. Calculation 6S0-1 882 states that for buried steel pipes of small diameter (up to 6" diameter), the seismic load effect is negligible. See Tech Evaluation 60084266-0010-0010. The supports will prevent the piping from floating while the flowable fill is being applied.

Penetration Seal Penetration seal W-19401-008 has been found to have a corroded sleeve and is in need of replacement. The original seal detail was shown on VTD 311694. The seal can not be repaired to the original detail due to the unavailability of the Biscoseal TC-28 (and its equivalent, TC-33) material used to seal around the sleeve and the penetration inside diameter. In lieu of the original seal detail, procedure SH.MD-SP.FBR-0014 Attachment 1 shall be used to fabricate a flanged boot seal. The new boot seal requires the use of at least four 1/4" Tapcon bolts with a minimum embedment of 1"and attached to the wall in lieu of the inside diameter of the penetration. This sleeve is in accordance with VTD 313642. The VTD states each Tapcon has a pull out load of 180 pounds. With four Tapcons the sleeve has a 720 pound capacity. The penetration has a centerline elevation of 94'-6". The maximum Probable Maximum Hurricane (PMH) water surge level is 113.8' per FSAR Section 3.4.3. The penetration sleeve is 8" in diameter and the pipe is 4" in diameter. Determining the exposed area as referenced in VTD provides approximately 35 square inches of area. Assuming the maximum elevation of 113'.8",

the penetration would see approximately 295 pounds of force ((113.8-94.5)/2.306 ft/psi*35 sq.in.), therefore the four (4) Tapcons have sufficient capacity for the penetration.

Instead of backfilling the excavated area with soil, a controllable low-strength material (CLSM)

(flowable fill, MM #1026607) is used in order to decrease the backfilling time and to eliminate the need for compaction. Per MM #1026607, the minimum density of the flowable fill is 120 pcf.

Per Calculation 6S0-1 882, page 90, the density of the compacted soil is 110 pcf. Therefore, the flowable fill will provide equal or greater missile protection than the compacted soil. Since the flowable backfill is similar to solid backfill, any thermal expansion and contraction of the piping is accommodated by the material. It may produce localized cracking in the fill along the pipe, but will not be a problem since the fill is not as strong as standard concrete.

The flowable fill can be poured directly against the containment since the pipe supports are already attached there. Also, seismically the piping is relatively rigid with the containment and during a seismic wave will undergo about the same movement as the corresponding buildings (ref. calc 6S0-1882).

Calculation 6S0-1 882 (AD S02), Qualification of Safety-Related Buried Commodities for Tornado Missile and Seismic Evaluation, has been revised due to the use of CLSM in lieu of Page 16 of 24 CC-AA-103-1001, Rev 3

CHANGE NO: 80101381 REVISION NO.:

Section Design Change Attribute compacted soil for the excavated area. See Section 4.1:.9 for discussion of the impacts to this calculation.

Per the flowable fill supplier's recommendations (Matt Grobelny of R.E. Pierson, (856)207-3899), the entire excavated area can be back-filled in one pour. Cure time is a function of temperature, humidity, moisture content of the ground and other variables. As such, a specific cure time cannot be provided. To expedite system return to operability, 1" thick plate may be placed over the backfill after 10-12 hours.

SUP03 contains the product information on the Enecrete WS coating material to be used on the containment exterior wall. The coating for the wall was a 1/16" EPDM rubber liner with a 1/8" hardboard applied to the outside, reference drawing 201007. The rubber liner and hardboard has degraded. Although not stated, the purpose of the 1/8" hardboard appears to be a protective boundary for the rubber liner during backfill and construction activities. The Enecrete WS is a waterproof protection layer for masonry structures. It provides a hardened water proof layer. Due to the use of the flowable fill, there is no need for the 1/8" hardboard.

  • Perform holiday testing of pipe coating in accordance with ASTM D 5162.

Modification Testing

  • ASME Section XI requires a system leakage test at normal operating pressure (NOP) and normal operating temperature (NOT).

Note: To expedite backfill of the pipe trench, a system pressure test lAW SC.MD-GP.ZZ-0035(Q) may be performed in lieu of the in service leak test at NOP/NOT. However, since the piping welds have already been coated, the system pressure test shall hold the test pressure for four (4) hours. Acceptance test criteria shall be in accordance with procedure SC.MD-GP.ZZ-0035(Q). Coordinate with In-Service Inspection Engineer for system pressure test.

" Operations shall also perform procedure SI.OP-ST.AF-0005 to ensure that the full flow requirements through each replaced line are able to be met and to allow for the in-service leak testing of all other replaced piping sections that were not hydrostatically tested. System testing indicated above should be coordinated with DCP 80101382 which reroutes sections of the No. 12 and 14 headers directly upstream of this replacement.

" Perform a ball drop test on the flowable fill in accordance with ASTM D 6024. If the diameter of indentation is less than 3 in., then the CLSM is suitable for the load application.

Ifthe diameter of indentation is greater than 3 in., then the CLSM is unsuitable or not ready for load application.
