VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 6 of 134 Components Affecting Safety-related Systems 1.0 Introduction 1.1 Purpose This report is part of the aging management review (AMR) of the integrated plant assessment (IPA) performed to extend the operating license of Vermont Yankee Nuclear Power Station (VYNPS). This report addresses nonsafety-related systems or components (SCs) whose failure could prevent satisfactory accomplishment of a safety function due to their proximity.

The concern is that age-related degradation of nonsafety-related SCs could adversely impact safety-related SCs through physical interaction. This encompasses nonsafety-related SCs directly or not directly connected to safety-related SCs, with seismic II/I, high energy, and moderate/low energy piping system interactions. This report demonstrates that the effects of aging on nonsafety-related passive mechanical components will be adequately managed so that the intended functions of safety-related SCs can be maintained consistent with the current licensing basis as required by 10 CFR 54.21(a)(3). Nonsafety-related structures that could adversely impact safety-related equipment were evaluated in structural aging management review reports and will not be discussed in this report. For additional information on the license renewal project overall scope and documentation, refer to the License Renewal Project Plan (Ref. 1).

The purpose of this engineering report is to demonstrate that aging effects for passive mechanical components in nonsafety-related systems or nonsafety-related portions of safety-related systems (meeting the scoping criteria of 54.4(a)(2)) will be adequately managed for the period of extended operation associated with license renewal. Section 2.0 reviews the 54.4(a)(2) criteria and establishes a logic flowchart (Attachment 3) to be used in the review of systems for spatial interaction. Section 3.0 then documents results of the 54.4(a)(2) flowchart process for each mechanical system at VYNPS. For systems that contain components meeting the 54.4(a)(2) criteria, the aging effects requiring management are identified. Section 4.0 then evaluates if existing programs and commitments adequately manage those effects identified in Section 3.0. The demonstration process is complete for the component under review when either:

  • The evaluation of existing programs demonstrates the aging effects requiring management are adequately managed so that the intended function(s) are maintained consistent with the current licensing bases for the period of extended operation, or;
  • Action(s) are proposed to augment existing or create new programs to manage the identified effects of aging.

Applicable aging effects were determined using EPRI report 1003056 Non-Class 1 Mechanical Implementation Guideline and Mechanical Tools (Ref. 3). This EPRI report provides the bases for identification of aging effects based on specific materials and environments and documents confirmation of the validity of the aging effects through review of industry experience. This aging management review report (AMRR), in conjunction with EPRI report 1003056, documents the identification and evaluation of aging effects requiring management for mechanical components.

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 7 of 134 Components Affecting Safety-related Systems 1.2 NRC/Industry Guidance on 10 CFR 54.4(a)(2) Scope On March 15, 2002 the Nuclear Regulatory Commission (NRC) issued a letter to the Nuclear Energy Institute (NEI) providing Guidance on the Identification and Treatment of Structures, Systems, and Components which Meet 10 CFR 54.4(a)(2). In this letter the NRC distinguished between two specific situations where nonsafety-related SSCs could affect the functions of safety-related SSCs. In the first situation, nonsafety-related SSCs are directly connected to safety-related SSCs (typically piping). (In this case, the scope of license renewal includes the nonsafety-related piping and supports up to and including the first seismic anchor beyond the safety/nonsafety interface.) In the second situation, nonsafety-related SSCs are not directly connected to safety-related SSCs but have the potential for spatial interaction. Therefore, nonsafety-related SSCs should be included in the scope of license renewal if, based on engineering judgment and operating experience, their failure has the potential to prevent the accomplishment of a safety function performed by safety-related SSCs. For such SSCs that are not directly connected to safety-related SSCs, the impact is the result of the spatial interaction between the SSCs. (Ref. 4)

On February 24, 2003, NEI issued a letter to the NRC providing Industry Guidance on Revised 54.4(a)(2) Scoping Criterion (Nonsafety Affecting Safety). NRC responded on March 21, 2003, with a letter providing Staff Comments to Industry Guidance on Revised 54.4(a)(2) Scoping Criterion (Nonsafety Affecting Safety) for License Renewal. NEI has also published an Industry Guideline for Implementing the Requirements of 10 CFR Part 54 - The License Renewal Rule which includes this guidance as Appendix F. (Ref. 2, 23, 24)

Taken together, these documents define two major areas where SSCs can meet the scoping criteria of 54.4(a)(2): loss of function, and physical interaction (directly-connected and spatial).

1.2.1 Nonsafety-related SSCs required to remain functional In the case where nonsafety-related SSCs are required to remain functional to support a safety function, those SSCs are within the scope of license renewal per 54.4(a)(2) and subject to aging management review.

1.2.2 Non-safety-related SSCs with the potential for physical interaction SSCs meeting the scoping criteria of 54.4(a)(2) for physical interaction will fall into the following areas:

1) Nonsafety-related (NSR) SSCs directly connected to safety-related (SR) SSCs
2) NSR SSCs that are directly or not directly connected to SR SSCs but have the potential for spatial interaction.

Section 2.0 of this report will review the specific evaluation criteria used to satisfy this guidance.

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 8 of 134 Components Affecting Safety-related Systems 2.0 Evaluation Criteria 2.1 Mechanical Systems and Components Meeting 54.4(a)(2) for Functional Support of a Safety Function A review of VYNPS mechanical systems and components to identify nonsafety-related SCs required to remain functional to provide a safety function is documented in the VYNPS scoping report and in AMRM-26, Main Condenser and MSIV Leakage Pathway (Ref. 7, 43). Attachment 1 provides a system level summary of this review.

2.2 Mechanical Systems and Components Meeting 54.4(a)(2) for Physical Interaction SSCs meeting the scoping criteria of 54.4(a)(2) for physical interaction are included in the following categories:

1) Nonsafety-related (NSR) SSCs directly connected to safety-related (SR) SSCs
2) NSR SSCs that are directly or not directly connected to SR SSCs but have the potential for spatial interaction.

2.2.1 Mechanical Systems and Components Meeting 54.4(a)(2) with Direct Connection to Safety-Related SSCs At VYNPS, certain components and piping outside of the safety class pressure boundary must be structurally sound in order to maintain the pressure boundary integrity of safety class piping.

Some components included in this group have been designated as safety class at VYNPS.

Each mechanical system safety-related to nonsafety-related interface is reviewed to identify the components located between the safety-related/nonsafety-related interface and the first equivalent anchor or structural boundary. Systems which include components that were found to be within the structural boundary or up to and including the first equivalent anchor are listed in Attachment 4 of this report, and the corresponding aging effects are listed in Attachment 2. provides a system level summary of this review. (Ref. 47) 2.2.2 Mechanical Systems and Components Meeting 54.4(a)(2) for Spatial Interaction The following sections address the different modes of spatial interaction.

2.2.2.1 Physical Impact or Flooding Nonsafety-related supports for non-seismic (including seismic II/I) piping systems and electrical conduit and cable trays with potential for spatial interaction with safety-related SCs are within the scope of license renewal per 54.4(a)(2) and subject to aging management review. These supports and components are addressed in a commodity fashion within civil/structural AMRRs.

Review of earthquake experience (Ref. 5) identified no occurrences of welded steel pipe segments falling due to a strong motion earthquake. Falling of piping segments is extremely rare and only occurs when there is a failure of the supports. This conclusion applies for new and aged pipe. Therefore, as long as the effects of aging on the supports for piping systems are managed, falling of piping sections is not credible except due to flow accelerated corrosion, and the piping section itself is NOT in scope for 54.4(a)(2) due to a physical impact hazard.

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 9 of 134 Components Affecting Safety-related Systems Missiles can be generated from internal or external events such as failure of rotating equipment. NSR design features that protect safety-related equipment from missiles are within the scope of license renewal per 54.4(a)(2). These features are addressed in civil/structural AMRRs.

The overhead-handling systems whose failure could result in damage to a system that could prevent the accomplishment of a safety function meet 54.4(a)(2) and are within the scope of license renewal. These features are addressed in civil/structural AMRRs.

Walls, curbs, dikes, doors, etc., that provide flood barriers to safety-related SCs and are within the scope of license renewal per 54.4(a)(2) have been included as part of the building structure and evaluated in the civil/structural AMRRs for that building.

2.2.2.2 Pipe Whip, Jet Impingement, or Harsh Environments In order to ensure the nonsafety-related portions of high energy lines were included in this 54.4(a)(2) review, the VYNPS SAR and associated site documentation was reviewed. The review of high energy line breaks for VYNPS is contained in the topical design basis document for accident-event combinations (Ref. 17, 66, 69). The systems that were evaluated for postulated pipe breaks are listed, and are described in more detail in Section 7 of the VYNPS Equipment Qualification Program Manual Volume 1 (Ref. 18).

High energy lines are defined as those lines whose service temperature is greater than or equal o

to 200 F or whose design pressure is greater than or equal to 275 psig (Ref. 17). At VYNPS, such lines are included in the following systems.

A. Inside the reactor building (including the main steam tunnel)

1. main steam (MS) system
2. core spray (CS) system
3. control rod drive (CRD) system
4. high pressure coolant injection (HPCI) system
5. reactor core isolation cooling (RCIC) system
6. reactor water clean-up (RWCU) system
7. residual heat removal (RHR) system
8. house heating (HB) system
9. feedwater (FW) system
10. sampling (SPL) system
11. standby liquid control (SLC) system B. Outside the reactor building
1. main steam (MS) system
2. house heating (HB) system
3. feedwater (FW) system
4. condensate (C) system
5. extraction steam (ES) system Many of these high energy lines are safety-related lines that are reviewed in the system mechanical aging management review reports. During review of the VYNPS systems as documented in Section 3.0 of this report, high energy systems were considered. If a high-energy line break (HELB) analysis assumes that a nonsafety-related piping system does not fail

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 10 of 134 Components Affecting Safety-related Systems or assumes failure only at specific locations, then that piping system is within the scope of license renewal per 10 CFR 54.4(a)(2) and subject to aging management review in order to provide reasonable assurance that those assumptions remain valid through the period of extended operation. For additional information on high energy lines, see the topical design basis document for accident-event combinations and Section 7 of the VYNPS Equipment Qualification Program Manual Volume 1 (Ref. 17, 18).

2.2.2.3 Leakage or Spray This section reviews the 54.4(a)(2) criteria and establishes a logic flowchart (see Attachment 3) for the review of mechanical systems for spatial interaction due to leakage or spray. The review utilizes a spaces approach for scoping of non-safety related systems with potential spatial interaction with safety related SSCs. The spaces approach focuses on the interaction between nonsafety-related and safety-related SSCs that are located in the same space. A space is defined as a room or cubicle that is separated from other spaces by substantial objects (such as wall, floors, and ceilings). The space is defined such that any potential interaction between nonsafety-related and safety-related SSCs is limited to the space. Non-safety related systems and components that contain water, oil, or steam, and are located inside structures that contain safety related SSCs, are included in scope for potential spatial interaction under criterion 10 CFR 54.4(a)(2), unless located in an excluded room. Attachment 1 to this aging management review report provides a listing of VYNPS mechanical systems as identified in the VYNPS scoping report (Ref. 7). In order to identify nonsafety-related systems or nonsafety-related portions of safety-related systems with the potential for adverse spatial interaction with safety-related SCs (54.4(a)(2)), a review of each mechanical system was required.

The first step is to determine if the system only contains air or gas. For these systems, a review of operating experience is performed. The review is to confirm that there have been no failures of air/gas systems that could have adversely impacted the ability of equipment to perform required safety functions. If this can be verified, then air systems are not in scope under 10 CFR 54.4(a)(2) (Ref. 6). A review of industry operating experience associated with nonsafety-related systems/components containing air/gas found six NRC documents and two INPO documents:

  • NRC Information Notices 81-38, 87-28, 89-26, 99-01, and 02-29
  • INPO Significant Operating Experience Report 88-01
  • INPO Significant Event Report 1-99 None of these documents described instances where nonsafety-related air/gas system leakage or ruptures adversely impacted safety-related equipment (Ref. 8, 9, 10, 11, 12, 13, 14, 15).

The operating experience review performed for VYNPS in report LRPD-05 confirmed that there have been no failures of air/gas systems that could have adversely impacted the ability of equipment to perform required safety functions (Ref. 16). Based on this review, air or gas systems are not in scope under 10 CFR 54.4(a)(2).

The second step is performed using a spaces approach to determine if the system has components in a safety-related structure. Systems that only contain components in office buildings, warehouses, yard area, etc, cannot interact with safety-related components and the

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 11 of 134 Components Affecting Safety-related Systems nonsafety-related system does not meet 54.4(a)(2). The following are seismic class 1 structures at VYNPS that contain safety-related plant equipment:

  • condensate storage tank (CST) valve and instrument enclosure
  • control room building
  • fuel oil transfer pump house
  • plant stack
  • reactor building
  • certain areas of the turbine building (diesel generator rooms, fuel oil day tank areas, ECCS keep-full station, and the area on elevation 252 where service water piping runs along the wall [key codes 6 - 8 and E - F]).

For further information on structures, see the VYNPS scoping report (Ref. 7).

Systems that contain liquid-filled nonsafety-related components in safety-related structures require as a third step: a component level evaluation to determine the potential for spatial interaction with a safety-related SSC from leakage or spray. For structures that contain safety related SSCs, there may be selected rooms (spaces) that do not contain any safety related SSCs. Components located in these rooms are not in scope for 54.4(a)(2). In light of §54.4(a)(2), the concern for these systems is the impact of a pressure boundary failure on safety-related systems. These failures could result in the nonsafety-related piping spraying or leaking on safety-related equipment. Consideration of hypothetical failures that could result from system interdependencies that are not part of the CLB and that have not been previously experienced is not required. (Ref. 6) Nonsafety-related components such as the VYNPS normal fuel pool cooling heat exchangers are an example of components that are in a safety-related building and could spatially interact with safety-related components.

See Attachment 3 for a graphic representation of the scoping review that is performed. For components that meet all three criteria, an aging management review is performed on the passive long-lived mechanical components. The passive mechanical components reviewed include piping, tubing, valve bodies, flow elements, heat exchangers, orifices, pump casings, rupture discs, sight glasses, strainer housings, tanks, filter housings and other passive components.

Insulation is installed on some equipment in VYNPS systems. For the evaluation of insulation, refer to LRPD-01, System and Structure Scoping Results, and AMRC-06, Aging Management Review of Bulk Commodities. (Ref. 7, 22)

Section 3.0 of this report documents the component level evaluation.

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 12 of 134 Components Affecting Safety-related Systems 3.0 Individual System Review for Spatial Interaction and Aging Effects This section documents the review against the spatial interaction criteria for each mechanical system identified in the VYNPS scoping report (Ref. 7). The electrical and structural systems identified in the VYNPS scoping report include no mechanical components and therefore are not part of this review.

3.1 System Reviews The flowchart of Attachment 3 is followed, and the basis for a systems review or exclusion is presented for each system. Attachment 1 provides a summary of this review at a system level.

3.1.1 MS, ES, & AS Instruments (101)

The purpose of the 101 system is to provide indication, alarm, and control functions for associated systems (main steam, extraction steam, and auxiliary steam). The passive mechanical components for this system are in the turbine building. (Ref. 7, 20, 21, 68)

Some components in this system are located in the main condenser and MSIV leakage pathway. Failure of these components could prevent satisfactory accomplishment of a safety function and the system is therefore within the scope of license renewal per 54.4(a)(2). These components are reviewed in AMRM-26, Main Condenser and MSIV Leakage Pathway. The remaining passive mechanical components in this system cannot affect safety-related components and are not subject to aging management review. (Ref. 7, 20, 21, 43) 3.1.2 HD & HV Instruments (103)

The purpose of the 103 system is to provide indication, alarm, and control functions for associated systems (heater drains and heater vents). This system does not require aging management review since its passive mechanical components are in the turbine building in areas that cannot affect safety-related components. (Ref. 7, 20, 21, 68) 3.1.3 SA & IA Instruments (105)

The purpose of the 105 system is to provide indication, alarm, and control functions for associated air systems. This system does not require aging management review since its passive mechanical components in buildings that contain safety-related equipment only contain dry air or gas. (Ref. 7, 20, 21, 68) 3.1.4 CST & DW Instruments (107)

The purpose of the 107 system is to provide indication, alarm, and control functions for associated systems (condensate storage and transfer and demineralized water).

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 34 of 134 Components Affecting Safety-related Systems of 54.4(a)(1) or (a)(3) are reviewed in AMRM-11, Service Water Systems. (Ref. 7, 20, 21, 33, 68)

Some components in this system outside of the safety class pressure boundary are required to be structurally sound to maintain the integrity of safety class piping. For piping in this structural boundary, pressure integrity is not required; however, piping within the pressure boundary depends on the structural boundary piping and supports in order for the system to fulfill its safety function. These components are reviewed in Attachment 4 of this AMRM and the corresponding aging effects are listed in Attachment 2. (Ref. 47)

The portion of the system in the service water pump area of the intake structure and the reactor building that requires aging management review due to potential spatial interaction includes stainless steel tubing, stainless steel and carbon steel piping and valve bodies exposed to raw water, condensation, and indoor air, as well as carbon steel strainer housings exposed to raw water and condensation. Carbon steel and stainless steel bolting is exposed to indoor air. (Ref.

The purpose of the TBCCW system is to supply emineralized water to cool various nonsafety-related auxiliary equipment located in the turbine building in support of power generation. This system does not require aging management review since its passive mechanical components are in the turbine building in areas that cannot affect safety-related components. (Ref. 7, 20, 21, 68) 3.1.68 Main Turbine Generator (TG)

The purpose of the TG system is to convert the thermodynamic energy of steam into a reliable source of electrical energy for use on the transmission network and the station auxiliary busses.

This system does not require aging management review since the passive mechanical components are in the turbine building in areas that cannot affect safety-related components.

(Ref. 7, 20, 21, 68) 3.1.69 Turbine Lube Oil (TLO)

The purpose of the TLO system is to provide lube oil for lubrication of the main turbine. This system does not require aging management review since its passive mechanical components are in the turbine building in areas that cannot affect safety-related components. (Ref. 7, 20, 21, 68)

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 35 of 134 Components Affecting Safety-related Systems 3.2 Summary of Aging Effects Requiring Management This section summarizes the aging effects requiring management for the material-environment combinations noted in the review of individual systems.

EPRI report 1003056 (Ref. 3) is used in this section to identify and evaluate aging effects requiring management. Aging effects that may result in loss of intended functions for non-Class 1 mechanical components are cracking (i.e., crack initiation, crack growth, and through-wall cracking), change in material properties, and loss of material. Attachment 2 contains a listing of component types, materials, environments, and the associated aging effects requiring management.

3.2.1 Carbon Steel Components (Exposed to Raw Water, Treated Water, Untreated Water, or Steam on Internal Surfaces and Indoor Air, Outdoor Air, or Condensation on External Surfaces)

The majority of the piping and valves in these systems are carbon steel. Several filter housings, air dryer towers, drain traps, flow elements, heat exchanger bonnets, heat exchanger shells, orifices, pump casings, sight glass housings, steam traps, strainer housings, and tanks are carbon steel. These components are exposed to raw water, treated water, untreated water, or steam on internal surfaces and indoor or outdoor air on external surfaces. Condensation may occur on un-insulated surfaces when the surface temperature is less than or equal to the dew point of the surrounding air.

Loss of material due to microbiologically influenced corrosion (MIC) or general, pitting or crevice corrosion is an aging effect requiring management for carbon steel surfaces exposed to raw water, treated water, untreated water, or steam. Loss of material from galvanic corrosion is an aging effect requiring management at interfaces between carbon steel and stainless steel components when an electrolyte is present. Loss of material from erosion or flow-accelerated corrosion is an aging effect requiring management for carbon steel surfaces at high velocity locations.

Cracking due to thermal fatigue is an aging effect requiring management since system temperature for some components is above the 220°F threshold for carbon steel thermal fatigue.

Loss of material from general corrosion is considered an aging effect requiring management for carbon steel external surfaces exposed to indoor air.

Loss of material from general, pitting, crevice and galvanic corrosion is an aging effect requiring management for carbon steel external surfaces exposed to weather and condensation.

3.2.2 Carbon Steel Components (Exposed to Lube Oil or Fuel Oil on Internal Surfaces and Indoor Air on External Surfaces)

Some piping, valves, bearing housings, heat exchanger bonnets, heat exchanger shells, pump casings, and tanks are carbon steel exposed to lube oil or fuel oil on internal surfaces and indoor air on external surfaces.

Loss of material from galvanic corrosion is an aging effect requiring management at interfaces between carbon steel and stainless steel components.

Erosion is not a concern due to the low oil velocities in these components.

Cracking due to thermal fatigue is not an aging effect requiring management since system temperatures remain below the 220°F threshold for carbon steel thermal fatigue.

Loss of material from general corrosion is considered an aging effect requiring management for carbon steel external surfaces exposed to indoor air.

3.2.3 Stainless Steel Components (Exposed to Raw Water, Treated Water, Untreated Water, or Steam on Internal Surfaces and Indoor Air, Outdoor Air, or Condensation on External Surfaces)

Some piping, tubing, and valves are stainless steel. Several filter housings, flow elements, heat exchanger bonnets, heat exchanger shells, orifices, pump casings, sight glass housings, strainer housings, and tanks, are stainless steel. These components are exposed to raw water, treated water, untreated water, or steam on internal surfaces and indoor air or outdoor air on external surfaces. Condensation may occur on un-insulated surfaces when the surface temperature is less than or equal to the dew point of the surrounding air.

Stainless steel is inherently resistant to general corrosion and erosion. Stainless steel internal surfaces are susceptible to loss of material due to MIC, pitting and crevice corrosion in the presence of high oxygen levels and contaminants. Therefore, loss of material is an aging effect requiring management for internal wetted surfaces.

Cracking due to stress corrosion and intergranular attack is an aging effect requiring management since system temperature for some components is above the 140°F threshold for these mechanisms in stainless steel.

Cracking due to thermal fatigue is an aging effect requiring management since system temperature for some components may be above the 270°F threshold for stainless steel thermal fatigue.

Loss of material from pitting and crevice corrosion is an aging effect requiring management for stainless steel external surfaces exposed to condensation or outdoor air since they are periodically wetted. Insulation is free of contaminants that could cause cracking of stainless steel. (Ref. 61) 3.2.4 Stainless Steel Components (Exposed to Fuel Oil on Internal Surfaces and Indoor Air on External Surfaces)

Some piping, tubing, valves, and pump casings are stainless steel exposed to fuel oil on internal surfaces and indoor air on external surfaces.

Stainless steel is inherently resistant to general corrosion and erosion. Stainless steel internal surfaces are susceptible to loss of material due to MIC, pitting and crevice corrosion if moisture

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 37 of 134 Components Affecting Safety-related Systems or contaminants are present in the fuel oil. Therefore, loss of material is an aging effect requiring management for internal wetted surfaces.

Cracking due to thermal fatigue is not an aging effect requiring management since system temperatures remains below the 270°F threshold for stainless steel thermal fatigue.

There are no aging effects requiring management for external stainless steel surfaces due to the inherent resistance of stainless steel to aging effects when not wetted or exposed to aggressive chemicals.

Some piping, tubing, pump casings, and strainer housings, tanks, and valves are stainless steel exposed to sodium pentaborate solution on internal surfaces and indoor air on external surfaces.

Stainless steel is inherently resistant to general corrosion and erosion. Stainless steel internal surfaces are susceptible to loss of material due to MIC, pitting and crevice corrosion in the presence of high oxygen levels and contaminants. Therefore, loss of material from internal wetted surfaces is an aging effect requiring management.

Cracking due to stress corrosion and intergranular attack is not an aging effect requiring management since system temperature remains below the 140°F threshold for these mechanisms in stainless steel.

Cracking due to thermal fatigue is not an aging effect requiring management since system temperature remains below the 270°F threshold for stainless steel thermal fatigue.

There are no aging effects requiring management for external stainless steel surfaces due to the inherent resistance of stainless steel to aging effects when not wetted or exposed to aggressive chemicals.

3.2.6 Copper Alloy > 15% Zn Components (Exposed to Raw Water, Treated Water or Untreated Water on Internal Surfaces and Indoor Air, Outdoor Air, or Condensation on External Surfaces)

Some piping and valves are copper alloy of unknown Zn content, therefore, >15% Zn is assumed. These components are exposed to raw water or treated water or untreated water on internal surfaces and indoor air or outdoor air on external surfaces. Condensation may occur on un-insulated surfaces when the surface temperature is less than or equal to the dew point of the surrounding air.

General corrosion of internal copper alloy surfaces is not expected due to the corrosion resistance of this material. However, raw water, treated water, and untreated water can cause

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 38 of 134 Components Affecting Safety-related Systems pitting corrosion, crevice corrosion, and MIC on internal surfaces. Copper alloy > 15% Zn that is not inhibited may also experience selective leaching in treated water. Erosion is not expected due to low flow velocities. Therefore, loss of material due to pitting corrosion, crevice corrosion, MIC, and selective leaching is an aging effect requiring management for internal surfaces of copper alloy components.

However, copper tubing is provided per ASTM B68 which is <15% Zn. Therefore, loss of material due to selective leaching is not an aging effect requiring management for copper tubing. (Ref. 70)

Cracking due to stress corrosion and intergranular attack is not an aging effect requiring management for copper alloy since an ammonia environment is not present.

Cracking due to thermal fatigue is not an aging effect requiring management since system temperatures remain low.

No aging effects require management for external surfaces of copper alloy components exposed to indoor air due to the corrosion resistance of copper alloys in air.

3.2.7 Copper Alloy > 15% Zn Components (Exposed to Fuel Oil or Lube Oil on Internal Surfaces and Indoor Air on External Surfaces)

Some tubing and valves are copper alloy of unknown Zn content, therefore, >15% Zn is assumed. These components are exposed to fuel oil or lube oil on internal surfaces and indoor air on external surfaces.

Loss of material from pitting, crevice corrosion, and MIC is an aging effect requiring management for copper alloy surfaces exposed to fuel oil and lube oil since water and contaminants may be present. Copper alloy > 15% Zn that is not inhibited may also experience selective leaching in oil. Erosion is not expected due to low flow velocities.

However, copper tubing is provided per ASTM B68 which is <15% Zn. Therefore, loss of material due to selective leaching is not an aging effect requiring management for copper tubing. (Ref. 70)

Cracking due to stress corrosion and intergranular attack is not an aging effect requiring management for copper alloy since an ammonia environment is not present.

Cracking due to thermal fatigue is not an aging effect requiring management since system temperature remains low.

No aging effects require management for external surfaces of copper alloy components exposed to indoor air due to the corrosion resistance of copper alloys in air.

Loss of material from pitting, and crevice corrosion is an aging effect requiring management for copper alloy external surfaces since they may be exposed to condensation.

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 39 of 134 Components Affecting Safety-related Systems 3.2.8 Gray Cast Iron Components (Exposed to Raw Water on Internal Surfaces and Indoor Air on External Surfaces)

Some piping and valves in the FP system are gray cast iron exposed to raw water on internal surfaces and indoor air on external surfaces.

Loss of material from general corrosion is considered an aging effect requiring management for gray cast iron external surfaces exposed to indoor air.

Loss of material due to microbiologically influenced corrosion (MIC) and general, pitting and crevice corrosion is an aging effect requiring management for gray cast iron surfaces exposed to raw water. Loss of material due to selective leaching is an aging effect requiring management for gray cast iron components. Erosion is not expected since this system is normally in standby.

Cracking due to thermal fatigue is not an aging effect requiring management since system temperature remains below the 220°F threshold for gray cast iron thermal fatigue.

3.2.9 Glass There are no aging effects requiring management for glass in a sight glass since glass is resistant to aging effects when not exposed to very hot water, hydrofluoric acids or caustics.

3.2.10 Bolting Loss of material from general corrosion is considered an aging effect requiring management for carbon steel bolting exposed to indoor air. Loss of material from general corrosion, pitting and crevice corrosion, MIC and galvanic corrosion is considered an aging effect requiring management for carbon steel bolting exposed to outdoor air.

Loss of material is not an aging effect requiring management for stainless steel in an indoor environment. Loss of material from MIC, pitting and crevice corrosion is an aging effect requiring management for stainless steel bolting in outdoor air.

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 40 of 134 Components Affecting Safety-related Systems 4.0 Demonstration That Aging Effects Will Be Managed Section 2.0 described the method for determining the liquid/steam filled systems or portions of systems requiring a review per 54.4(a)(2). Section 3.0 documented the review of the systems and the corresponding component types that are subject to aging management review. For those component types subject to aging management review, section 3.0 also documented the determination of aging effects requiring management. The aging management review is completed by demonstrating that existing programs, when continued into the period of extended operation, can manage the aging effects identified in section 3.0. No further action is required for license renewal when the evaluation of an existing program demonstrates that it is adequate to manage the aging effect such that corrective action may be taken prior to loss of the system intended functions. Alternately, if existing programs cannot be shown to manage the aging effects for the period of extended operation, then action will be proposed to augment existing or create new programs to manage the identified effects of aging.

Demonstration for the purposes of this license renewal technical evaluation is accomplished by establishing a clear relationship among

1) the components under review,
2) the aging effects on these items caused by the material-environment-stress combinations which, if undetected, could result in loss of the intended function such that the system could not perform its function(s) within the scope of license renewal in the period of extended operation, and
3) the credited aging management programs whose actions serve to preserve the system intended function(s) for the period of extended operation.

As documented in section 2.0, the systems requiring a review per 54.4 (a)(2) are those where nonsafety-related SSCs are required to remain functional to support a safety function, and those with the potential for physical interaction (directly-connected and spatial). Passive long-lived components performing an intended function within these systems are subject to aging management review. lists component types and identifies the aging effects requiring management for each material and environment combination. The Diesel Fuel Monitoring Program, Fire Water System Program, Flow-Accelerated Corrosion Program, Instrument Air Quality Program, Oil Analysis Program, One-Time Inspection Program, Periodic Surveillance and Preventive Maintenance Program, Selective Leaching Program, Service Water Integrity Program, System Walkdown Program, Water Chemistry Control - Auxiliary Systems Program, Water Chemistry Control - BWR Program, and Water Chemistry Control - Closed Cooling Water Program in combination will manage the effects of aging, thereby precluding loss of the intended functions of the system.

Sections 4.1 through 4.13 provide the clear relationship between the component, the aging effect, and the aging management program actions which preserve the intended functions for the period of extended operation. Section 4.14 identifies applicable time-limited aging analyses associated with 54.4(a)(2) systems.

The System Walkdown Program manages loss of material for external carbon steel, gray cast iron, stainless steel, and copper alloy components by visual inspection of external surfaces. Since some internal carbon steel surfaces are exposed to the same indoor air environment as the external surfaces, the external surfaces will be representative of the internal surfaces. Thus, loss of material on internal carbon steel surfaces in an indoor air environment is also managed by the System Walkdown Program.

This program applies to component types indicated on Attachment 2. For additional information on this program, see VYNPS Report LRPD-02, Aging Management Program Evaluation Results. (Ref. 19)

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 127 of Components Affecting Safety-related Systems 134 Attachment 4 - Review of Nonsafety-Related SSCs Connected to Safety-Related SSCs Introduction - Review for Structural Interaction Nonsafety-related SSCs directly connected to safety-related SSCs (typically piping) are subject to aging management review for 10 CFR 54.4(a)(2). (In this case, the scope of license renewal includes the nonsafety-related piping and supports up to and including the first seismic or equivalent anchor beyond the safety/nonsafety interface such that the safety-related portion of the piping will be able to perform its intended function.

Some components in this group are considered safety-class at VYNPS.) For piping in this structural boundary, pressure integrity is not required; however, piping within the safety class pressure boundary depends on the structural boundary piping and supports in order for the system to fulfill its safety function. For VYNPS, the structural boundary is defined as the portion of a piping system outside the safety class pressure boundary, yet relied upon to provide structural support for the pressure boundary. The structural boundary is often shown on piping isometric drawings and is considered synonymous with the first seismic or equivalent anchor. (Ref. 47)

Approach VYNPS mechanical system safety-related to nonsafety-related interfaces were reviewed from the safety-related/nonsafety-related interface to the first seismic or equivalent anchor or structural boundary.

Each of the LRA drawings, along with other flow diagrams, was reviewed to identify safety/nonsafety interfaces. Nonsafety-related piping systems connected to safety-related systems were traced back to the structural boundary or to a point that includes an adequate portion of the nonsafety-related piping run to conservatively include the first seismic or equivalent anchor. An equivalent anchor is a combination of hardware or structures that together are equivalent to a seismic anchor. A seismic anchor is defined as hardware or structures that, as required by the analysis, physically restrain forces and moments in three orthogonal directions. The physical arrangement as analyzed insures that the stresses that are developed in the safety-related piping and supports are within the applicable piping and structural code acceptance limits. If isometric drawings were not readily available to identify the structural boundary, connected lines were traced back to a point beyond the safety/nonsafety interface such as a base-mounted component, flexible connection, or the end of a piping run (such as a drain line). This is consistent with the guidance in NEI 95-10, Appendix F.

All components required or conservatively considered to provide structural support for safety-related portions of systems are included in Attachment 2. (Ref. 49, 50, 51, 52, 53, 54, 55, 59)

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 128 of Components Affecting Safety-related Systems 134 Attachment 4 - Review of Nonsafety-Related SSCs Connected to Safety-Related SSCs Special Note for Two Cases The following nonsafety-related systems highlighted on LRA drawings do not have a structural nonsafety/safety interface at the license renewal boundary flags since the system is nonsafety-related:

1. Main Condenser and MSIV Leakage Pathway, AMRM-26 (LRA-33600-A00217, LRA-G-191156, and LRA-G-191164)
2. Fire Protection, AMRM-17 and AMRM-18 (LRA-G-191163 sh.1, LRA-G-19163 sh.2, LRA-G-191163 sh.3, and LRA-G-191163 sh.4)

Although the fire protection system (FP) has no nonsafety/safety interface at the license renewal boundary flags, some mechanical FP components do provide structural support for the safety-related service water (SW) system. The mechanical components that provide structural support for the SW system are reviewed in AMRM-17. (Ref. 39)

Summary of Results for Structural Interaction The following systems (system codes as identified in EMPAC) include components that were found to be within the structural boundary or up to and including the first equivalent anchor. All components required or conservatively considered to provide structural support for safety-related portions of systems are included in Attachment 2.

AMRM 30 open items OI 5: V62-34 is not located in the control room. The valve is physically located in the SJAE room in the turbine building. Valve FCV-101-34, which is required for the Main Condenser and MSIV leakage pathway is also in the SJAE room as shown on dwg G-191182 at grid M/4. This valve can be operated from CRP 9-23. DWG 5920-5499 shows this valves body material as ASTM A217-C5. Im not sure why V62-34 is required for LR. VY needs to review OP-2113 for numbering consistency.

RE: Parts of VY Sewage System in LR Scope due to a(2)

The original plant design had a bathroom on the hot side in the maintenance shop, but we expanded the shop and got rid of it decades ago. The piping got demolished and pulled back to the bathrooms on the non-rad side office area outside the maintenance shop. There are no bathrooms anywhere in the RCA, including the rx and turb bldgs. I dont know of any waste piping running through the RCA. It all runs from the bathrooms in the office areas directly outside below grade. There are no waste lines in the rx and turb bldg RCA. Technically speaking, we consider the maintenance dept office areas just outside the shop (where there are bathrooms) to be in the New Warehouse. There are potable water lines running from the back fan room through the turb bldg to the bathrooms in the maintenance office area. There are no connections to take potable water off this piping in the turb bldg (it just transits the area). I know of no 2 over 1 considerations for this pipe.

RE: NB orifices - possible (a)(2)

1. RO-2-3-7A/B and 8A/B are shown on G-191159 Sh. 5 at grid G and 3/4. These ROs are in the recirculation pump seal cavity instrument lines.
2. Although the other ROs are listed in EMPAC, I don't believe any of the other listed orifices were ever installed. The ROs (except ROs 2-76A-H)were originally listed in the Valve & Specialty list (Dwgs A-191137 Part 2) and may even have been purchased via PO NY-706116 which is the original piping PO. The ROs were spec'd for 1/4" diameter, pipe schedule 160 and were rated for 1250 psia and 575 degrees F.
3. The RO numbers in the instrument lines penetrating containment are the same as the excess flow check valves in the corresponding lines except where an RO is upstream of more than 1 penetration. I believe the following is true,refer to G-191267 Sh.1.

Excess flow check valve (EFCV) SL-2-3-17A/B and SL-2-3-15A/B are downstream of RO-2-3-15A/B. Therefore RO-2-3-17A/B were not installed.

Excess flow check valve (EFCV) SL-2-3-33 and SL-2-3-27 are downstream of RO-2 27. Therefore RO-2-3-33 was not installed.

Excess flow check valve (EFCV) SL-2-3-35 and SL-2-3-25 are downstream of RO-2 25. Therefore RO-2-3-35 was not installed.

3. Orifices RO-2-3-21A-D, 23A-D, and 31A-P were not installed in the jet pump instrument lines because the instrument lines already had a restriction equivalent to a 1/4" orifice. See UFSAR page 5.2-30 and UFSAR change no. 17/096.
4. I can't find any references to ROs 2-3-76A-H or EFCVs with corresponding numbers.

These ROs were not listed in the Valve and Specialty list. There are no EFCVs with similar numbers in the App J or IST programs.

RE: RIP components with possible spatial impact

1. P-200-1B, I performed a walk down of all three cooling tower spray pond blow down pumps. These pumps are located just north of the west cooling tower. The pumps are remote from any required components associated with LR required components. Piping to the pumps has been removed and there is no potential water pressurization source.

There is no credible potential for an (a) (2) flooding/spray spatial impact.

2. Valves V72-36A/B/C/D, these service air valves are shown on drawing G-191160 Sheet 6 at grid L/9-10.The air supply piping has been capped and the valves are closed and have a hose connection fitting. There is no potential water pressurization source.

There is no credible potential for an (a) (2) flooding/spray spatial impact.

3. Valves V16-19-32A/B, 53, 54, 54A/B/C, these atmosphere control valves used to provide instrument air to the PCAC system before VY inerted the drywell. The instrument air supply is shown on drawing G-191160 Sheet 4 at grid I/6. The valves are shown on G-191175 Sheet 1 at grid J/12. The discharge piping is to the PCAC system which contains nitrogen or air when the drywell is open during RFOs. I performed a walk down of these valves which are located on the wall separating the CRD pump room from the torus toward the CRD pump motor end of the wall. There is no potential water pressurization source. There is no credible potential for an (a) (2) flooding/spray spatial impact.
4. P-37-1A/B, the RDW decontamination shop sump pumps are not located in the reactor building as shown on their EMPAC listing. The pumps are located in the turbine building as shown on drawing G-191144 at grid E/18 and drawing G-191146 at grid J/16. These pumps are located in the maintenance shop tool crib and are remote from any required components associated with LR required components. There is no credible potential for an (a) (2) flooding/spray spatial impact.
5. Valves V12-101, 102, 105, 106, 109, 110, 112, 116, and DCP-1, 2, 3, 4 and 5 are process side valves that were associated with the ECP system and they are located in the A RWCU pump room. The valves are shown on drawing G-191178 Sheet 1. DCP-1, 2, 3, 4 and 5 valves are isolated since the piping was cut and capped. The other valves are isolated from any potential pressurization sources other than the ECP test vessel since the piping was cut and capped. Valves V70-197A/B/C/D/E/F are RBCCW system valves (Drawing G-191159 Sheet 3 grid N/O-7) which provided cooling water to the ECP test vessel. Valves V70-197A/B are closed but still connected to the RBCCW system

VYNPS License Renewal Project AMRM-30 Revision 1 Aging Management Review of Nonsafety-related Systems and Page 134 of Components Affecting Safety-related Systems 134 Attachment 5 - Walkdown Summaries piping. The RWCU pump rooms are contaminated and require a RWP for entry. It appears that the RBCCW system could potentially pressurize the ECP test vessel via leaking valves. Please advise as to what course of action is required to resolve this issue. I believe that the RWCU system containment isolation valves are located higher than this equipment.

Refuel Platform Compressor I dont see much of a risk of spray or leakage with the compressor system. The receiver is maintained between 80 and 140 psig by the compressors (lead - lag). Of course the air compressor system is attached to and rides along with the Platform. The compressor power supply is always opened by procedure when the operators leave the Platform unattended. The air line runs from the compressor up the side of the Platforms A-frame, along the top by hose to the where the orange take up reels are, and then by hose down the mast to the fuel grapple. We rarely experience any leaks - none that I can recall, actually.

Enclosed are photos to help illustrate.
