ANO-2 License Renewal Project Engineering Report Aging Management Review of Nonsafety-related Systems and A2-NE-2003-001-1 Components Affecting Safety-related Systems Page 7 of 77 1.0 Introduction 1.1 Purnose This report is part of the aging management review for the integrated plant assessment performed to extend the operating license of Arkansas Nuclear One Unit 2 (ANO-2). 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 spatial interaction. This encompasses seismic KI/I high energy, and moderatellow energy piping systems. The report demonstrates the effects of aging on nonsafety-related passive mechanical components are adequately managed so that the intended functions of safety-related SCs can be maintained consistent with the current licensing basis as required by 10 CER 54.21(a)(3).

Nonsafety-related structures that could adversely impact safety-related equipment were evaluated in the 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 engineering report LRPG-01, License Renewal Project Plan. (Ref. 2, 20)

The purpose of this engineering report is to demonstrate that the aging effects for passive mechanical components in nonsafety-related systems or nonsafety-related portions of safety-related systems (meeting scoping criterion 54.4(a)(2)) can be adequately managed for the period of extended operation associated with license renewal. Section 2 reviews the 54.4(a)(2) criteria and establishes a logic flowchart (Attachment 3) for the review of systems. Section 3 then completes the 54.4(a)(2) flowchart process for each mechanical system at ANO-2. 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. 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, Revision 3. The EPRI report provides the generic bases for the identification of aging effects based on specific materials and environments and documents the confirmation of the validity of the aging effects through review of industry experience. This aging management review report, in conjunction with EPRI report 1003056, documents the identification and evaluation of aging effects requiring management for the components. (Ref. 1)

ANO-2 License Renewal Project Engineering Report Aging Management Review of Nonsafety-related Systems and A2-20034001-1 Components Affecting Safety-related Systems Revision 1 1.2 Industry/NRC 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) (Reference 23) providing "Guidance on the Identification and Treatment of Structures, Systems, and Components which Meet 10 CPR 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 (typicallypiping). (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.

Based on the license renewal rule and the guidance in Reference 23, components meeting the scoping criterion of 54.4(a)(2) will fall into the following areas.

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

The following sections address the different modes of spatial interaction. Those interactions can occur in the following forms:

  • physical impact such as in a seismic event (Seismic f/1),
  • pipe whip, jet impingement, orharsh environmentresulting from a piping rupture, or
  • damage due to leakage or spray from nonsafety-related SSCs Protective features (whip restraints, spray shields, supports, barriers, etc.) may be installed to protect safety-related SSCs against spatial interaction with nonsafety-related SSCs. Such protective features credited in the plant design are included within the scope of license renewal and are subject to aging management review. Where those protective features provide adequate protection, the nonsafety-related system itself is excluded from the scope of license renewal.

These protective features are typically associated with a structure and are addressed in the structural aging management reviews.

Physical Impact This category concerns the potential spatial interaction of nonsafety-related SSCs falling on or otherwise physically impacting safety-related SSCs such that safety functions may not be accomplished.

ANO-2 License Renewal Project Engineering Report Aging Management Review of Nonsafety-related Systems and

-IEi20o 1-Components Affecting Safety-related Systems PRe 9 of 77 All NSR supports for non-seismic or seismic II/I piping systems with a potential for spatial interaction with safety-related SSCs are in the scope of license renewal per 54.4(a)(2) and subject to aging management review.

Based on earthquake experience data (Ref. 25) that includes aged pipe, the following conclusions can be drawn.

  • NO experience data exists 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.
  • These conclusions apply for new and aged pipe.

As long as the effects of aging on the supports for these piping systems are managed, falling of piping sections is not considered credible, and the piping section itself is NOT in scope for 54.4(a)(2) due to the physical impact hazard. The effects of spray and leakage must be considered.

Missiles can be generated from internal or external events such as failure of rotating equipment.

Inherent NSR features that protect safety-related equipment from missiles should be considered within the scope of license renewal per 54.4(a)(2) and subject to aging management review.

The overhead-handling systems whose failure could result in damage to any system that could prevent the accomplishment of a safety function meet the criteria of 54.4(a)(2) and should be considered within the scope of license renewal and subject to aging management review.

Pipe Whip. Jet Impingement. or Harsh Environments Pipe whip, jet impingement, and harsh environment effects on safety-related equipment are typically addressed in site-specific analyses of high and medium energy line breaks. Section 3.6.1 of the ANO-2 SAR identifies those systems where the fluid temperature exceeds 200 OF or the pressure exceeds 275 psig that were evaluated for pipe breaks.

If a HELB analysis assumes that a NSR piping system does not fail or assumes failure only at specific locations, then that piping system should be within the scope of license renewal per 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.

If required safety-related equipment is not protected from the effects of a high-energy line break (HELB), then the high energy piping is within the scope of license renewal and subject to aging management review.

ANO-2 License Renewal Project Engineering Report Aging Management Review of Nonsafety-related Systems and A2-Me 2003-001-1 Components Affecting Safety-related Systems Page 10 of 77 Leakage. Spray. or Flooding Moderate and low energy systems have the potential for spatial interactions of spray and leakage.

Nonsafety-related systems and nonsafety-related portions of safety-related systems with the potential for spray or leakage that could prevent safety-related SSCs from performing their required safety function are considered in the scope of license renewal and subject to aging management review.

Air and gas systems (non-liquid) systems are not a hazard to other plant equipment. Components that do not contain liquids cannot adversely affect safety-related SSCs due to leakage or spray.

Operating experience indicates that nonsafety-related systems containing only air or gas have experienced no failures due to aging that could impact the ability of safety-related equipment to perform required safety functions. There are no credible aging effects for these systems when the environment is a dry gas. These systems need not be considered in the scope of license renewal for scoping criterion §54A(a)(2).

Nonsafety-related systems and nonsafety-related portions of safety-related systems containing steam or liquid that are near safety-related equipment should be considered 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. 24) Failure resulting from long-term exposure to conditions resulting from a failed NSR SSC (such as leakage or spray) are considered hypothetical. Leakage from liquid-filled low-energy systems is detected during routine operator rounds or system Walkdown long before it could impact the performance of safety-related equipment. The leakage from these low-energy systems has typically resulted from isolated pitting that is not indicative of the overall condition of the piping. Follow-up actions would direct leakage away from equipment and therefore prevent its failure. Additional evaluations of the condition of the piping would then be performed.

Walls, curbs, dikes, doors, etc., that provide flood barriers to SR SSCs, should be within the scope of license renewal per 54.4(a)(2).

Section 2 of this report will review the specific evaluation criteria used to satisfy this guidance.

ANO-2 License Renewal Project Engineering Report Aging Management Review of Nonsafety-related Systems and A2-MEv2003so01-1 Components Affecting Safety-related Systems Raevision 7 2.0 Evaluation Criteria 2.1 Mechanical Systems and Components that Meet the 54.4(a)(2) Criteria for 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. Attachment 1 to this aging management review report provides a listing of the ANO-2 mechanical systems as identified in the ANO-2 scoping report (Ref. 3). 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 required. The review confirms 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 is verified, then air systems do not require further aging management reviews under 10 CFR 54.4(a)(2). A review of industry operating experience associated with nonsafety-related systems/components containing air/gas found four NRC documents. None of these documents described instances where nonsafety-related air/gas system leakage or ruptures adversely impacted safety-related equipment. These documents are: NRC Generic Letter 88-14 andNRC InformationNotices 81-38, 87-28, and 99-01. (Ref. 13,14,15,16,20) The operating experience review that was performed for ANO-2 in report A2-EP-2002-003-0 (Ref. 4) 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. Since this was verified, air or gas systems do not require further aging management reviews under 10 CFR 54.4(a)(2).

The second step is to determine if the system has components in a safety-related structure.

Systems that only contain components in the turbine building, office buildings, warehouses, etc, cannot interact with safety-related components and the nonsafety-related system does not require aging management review. The ANO-2 containment building, auxiliary building, intake structures, and emergency diesel fuel oil storage vault are the primary seismic class 1 structures at ANO-2 and contain the safety-related plant equipment. For further information on the structures and their functions, see the ANO-2 scoping report 02-R-2008-01.

Those systems that contain liquid-filled nonsafety-related components inside of safety-related structures require as a third step a component level evaluation to determine if there is a potential for spatial interaction with safety-related SSC from leakage, or spray. Nonsafety-related components such as the ANO-2 spent fuel pool coolers are an example of components that are in a safety-related building, but could not spatially interact with safety-related components since they are in a separate room of the building.

ANO-2 License Renewal Project Engineering Report Aging Management Review of Nonsafety-related Systems and Revision 1 Components Affecting Safety-related Systems Page 12 of 77 See Attachment 3 for a graphic representation of the screening that is performed. For those components that meet all three criteria, an aging management review is performed on the passive mechanical components that identify the aging effects requiring management for the material and environment combinations. The passive mechanical components reviewed include piping, tubing, valve bodies, heat exchangers, orifices, pump casings, tanks, filter housings and other passive components.

2.2 Mechanical Systems and Components that Meet the 54.4(a)(2) Criteria for Reasons Other than Leakage or Spray Nonsafety-related supports for non-seismic (including seismic M) piping systems and electrical conduit and cable trays with a 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 have been addressed in a commodity fashion within civil/structural AMRs. As long as the effects of aging on the supports for piping systems are managed, falling of piping sections is not considered credible, and the piping section itself is NOT in scope for 54.4(a)(2) due to the physical impact hazard.

Missiles can be generated from internal or external events such as failure of rotating equipment.

Inherent NSR features that protect safety-related equipment from missiles are within the scope of license renewal per 54.4(a)(2) and subject to aging management review. 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, are considered to meet 54.4(a)(2) and are within the scope of license renewal and subject to aging management review. These features are addressed in civil/structuralAMRRs.

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/structuralAMR~s for that building.

2.3 Review of ANO-2 High Energy Line Breaks (HELBs)

In order to ensure the nonsafety-related portions of high energy lines were included in this 54.4(a)(2) review, the ANO-2 SAR and associated site documentation was reviewed. SAR Section 3.6, Protection Against Dynamic Effects Associated With The Postulated Rupture Of Piping, contains the review of high-energy line breaks for ANO-2. The SAR lists the systems that were evaluated for postulated pipe breaks and identifies that these analyses are described in more detail in the ANO-Engineering Standard NES-13, Environmental Qualification-Environmental Service Conditions. (Ref. 11, 26)

Section 3.6.1 of the ANO-2 SAR identifies those systems where the fluid temperature exceeds

ANO-2 License Renewal Project En2Mge2ei34)R1p1 Aging Management Review of Nonsafety-related Systems and Re20sion 1 Components Affecting Safety-related Systems Page 13 of 77 I

200TF or the pressure exceeds 275 psig that were evaluated for pipe breaks. The following systems were included:

A.

Inside containment

1.

Reactor coolant piping, including pressurizer surge line and spray line piping

2.

Chemical and volume control system (CVCS) letdown and makeup piping

3.

Safety injection system (SIS) piping (only the portions of this system normally subjected to safety injection tank pressure)

4.

Main steam piping

5.

Steam generator blowdown piping

6.

Main feedwater piping

7.

Emergency feedwater piping

8.

Shutdown cooling piping from reactor coolant nozzle to the first isolation valve B.

Outside containment

1.

Main steam piping (including extraction steam piping and steam supply piping to the main feedwater pump turbine drivers and the emergency feedwater pump turbine driver)

2.

Main feedwater piping

3.

Steam generator blowdown piping

4.

CVCS letdown piping (from containment penetration to letdown heat exchanger) and makeup piping (from charging pump discharge to containment penetration).

5.

Emergency feedwater piping (from pump discharge to containment penetration)

The majority of these high energy lines are safety-related lines that are reviewed in the system mechanical aging management review reports. During the review of the ANO-2 systems as documented in Section 3 of this report, these high energy systems as documented in NES-13 were considered to ensure any components that are part of nonsafety-related high energy lines that can effect safety-related equipment are included in this report. For additional information on the high energy lines, see NES-13, Environmental Qualification-Environmental Service Conditions. (Ref. 11,26)

There are nonsafety-related stainless steel, piping and valves, and a filter housing in this system code primarily in the seal cavity vents and bleedoffs that have an internal environment of treated borated water and require a review for 54.4(a)(2).

Loss of material from pitting corrosion, crevice corrosion and MIC is an aging effect requiring management for the stainless steel component internal surfaces. Cracking from IGA/SCC is an aging effect requiring management for the portions of the system that operate above the 140 OF threshold for this effect. Loss of material is not an aging effect requiring management for the external stainless steel surfaces due to the inherent corrosion resistance of stainless steel.

The reactor coolant pump motor coolers are internal to the reactor coolant pump motors and their failure would not impact safety-related equipment. The lube oil system has a leakage collection system reviewed in engineering report 02-R-2005-12 that would collect and store lube oil leakage and prevent impact to safety-related equipment. Therefore, these components do not require aging management review per 54.4(a)(2). (Re. 5, 8)

Components Affecting Safety-related Systems PaRe 48 of 77 4.0 Demonstration that Aging Effects Are 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) and the corresponding typical components that are subject to aging management review. For those components, Section 3.0 documented determination of possible 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 maybe 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 is proposed to augment existing or create new programs to manage the identified effects of aging.

Demonstration for the purposes of the aging management review 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 the 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) include those nonsafety-related systems with the potential for spatial interactions that could prevent the accomplishment of safety functions performed by safety-related systems. Passive long-lived components performing an intended function within these systems are subject to aging management review. A review of aging management programs for SCs subject to aging management review for spatial interaction is provided below.

The results of the aging management review are that the following aging management programs are adequate to manage the effects of aging for systems requiring a review per 54.4(a)(2):

Boric Acid Corrosion Prevention Program Flow Accelerated Corrosion Program System Walkdown Program Water Chemistiy Control Program Bolting and Torquing Activities

  • . 1 ANO-2 License Renewal Project Engineering Report Aging Management Review of Nonsafety-related Systems and REvisio* 1 Components Affecting Safety-related Systems Re 49soon If future operating experience indicates that the above programs are not adequate, then the corrective action program will lead to appropriate program enhancements or additional programs in order to effectively manage the effects of aging.

Sections 4.1 through 4.5 discuss these programs and provide the clear relationship between the component, the aging effect and the aging management program action(s) which preserve the intended function(s) for the period of extended operation. Section 4.6 discusses time-limited aging analyses associated with 54.4(a)(2) systems. For a comprehensive review of the programs credited for the license renewal of ANO-2 and a demonstration of how these programs will manage the aging effects, see engineering report A2-EP-2002-002, Evaluation of Aging Management Programs.

4.1 Water Chemistry Control Proaram Many of the systems have treated water as an environment where water chemistry is monitored as a part of the Water Chemistry Control Program. The Water Chemistry Control Program is only listed in Attachment 2 for the purpose of documenting that the program can aid in managing loss of material and cracking for systems containing treated water. The System Walkdown Program is the aging management program that is primarily credited for managing loss of material and cracking in treated water systems. For additional information on the Water Chemistry Control Program, see engineering report A2-EP-2002-002, Evaluation of Aging Management Programs.

42 Boric Acid Corrosion Prevention Program The Boric Acid Corrosion Prevention Program was established to reduce leakage and corrosion from borated water. This program will manage the loss of material from boric acid corrosion of the bolting. This program is also credited with managing the aging effect of loss of mechanical closure integrity for bolted closures that may be exposed to borated water if leakage occurs. For additional information on the Boric Acid Corrosion Prevention Program, see engineering report A2-EP-2002-002, Evaluation of Aging Management Programs.

4.3 System Walkdown Program Operating experience indicates that routine walkdowns, in conjunction with a flow accelerated corrosion prevention program, provide reasonable assurance that leaks from nonsafety-related SCs do not progress to the point of impacting the ability of safety-related SCs to perform required safety functions. The waLlcdowns performed under the System Walkdown Program will detect leakage and spray from liquid-filled low-energy systems before it could impact the performance of safety-related equipment. Follow-up actions will direct leakage away from equipment and take corrective actions which will prevent failure. The System Walkdown Program manages the aging effects of loss of material and cracking due to SCC/IGA for all components, loss of mechanical closure integrity on bolted closures, and cracking due to thermal

ANO-2 License Renewal Project Engineering Report Aging Management Review of Nonsafety-related Systems and A2-ME2003-001-1 Components Affecting Safety-related Systems Page 50 of 77 fatigue on components subjected to high temperatures. For additional information on the System Walkdown Program, see engineering report A2-EP-2002-002, Evaluation of Aging Management Programs.

4.4 Flow Accelerated Corrosion Program Industry operating experience has shown that age-related failures of nonsafety-related SCs containing steam or liquid that could prevent safety-related components from accomplishing their safety function have only occurred as a result of flow accelerated corrosion (FAC). FAC programs manage loss of material due to FAC to prevent failures. The Flow Accelerated Corrosion Program is credited with managing the loss of material from the components susceptible to FAC as identified on Attachment 2. For additional information on the Flow Accelerated Corrosion Program, see engineering report A2-EP-2002-002, Evaluation of Aging Management Programs.

4.5 Bolting and Torguing Activities Bolting and Torquing Activities are credited with preventing loss of mechanical closure integrity for the bolted closures exposed to high temperatures. For additional information on Bolting and Torquing Activities, see engineering report A2-EP-2002-002, Evaluation of Aging Management Programs.

4.6 Metal Fatigue TLAA Engineering report A2-EP-2002-005 documents evaluation of components in systems that require a review per 54.4(a)(1) or (a)(3) and are subject to metal fatigue. The evaluations performed in A2-EP-2002-005 are applicable to the additional nonsafety-related components that can affect safety-related SSC and are in these same systems since they are the same material and environment combinations.

The walkdowns performed as a part of the System Walkdown Program will manage cracking due to fatigue on components in the systems that only require a review for 54.4(a)(2). The System Walkdown Program will detect leakage and spray from liquid filled low energy systems as a result of cracking before it could impact the performance of safety-related equipment. Follow-up actions will direct leakage away from equipment and take corrective actions which will prevent its failure. As a result a fatigue evaluation is not required for these components.

The results of this review are documented in. Based on this scoping review, the systems with components requiring review for 54.4(a)(2) were further evaluated in order to identify the aging effects for the components that required a review. Section 4 then identified what aging management programs would manage the effect of aging that were identified. Attachment 2 contains the aging management review results for the components types in the systems in scope for 54.4(a)(2). The following aging management programs address the aging effects that require management for the nonsafety-related SC that can affect safety-related SC.

In conclusion, the programs described in Section 4.0 will provide reasonable assurance that the effects of aging on the ANO-2 passive mechanical nonsafety-related components will not cause failures could prevent safety-related SSCs from accomplishing required safety functions consistent with the current licensing basis throughout the period of extended operation.

iME o2003n01-1 and Components Affecting Safety-related Systems PaRe 77 of 77 Walkdown Summaries In order to determine the potential impact to safety-related equipment, the following walkdowns were completed:

3/28/03 Ted Ivy and Stan Batch walked down:

  • The ANO-2 intake structure and outside area and verified the screenwash piping, chemical addition piping, chemical addition tanks, and intake structure floor drain piping cannot affect the safety-related equipment in the intake structure. The nonsafety-related vacuum breaker components are surrounded by spray shields so they cannot impact safety-related equipment.

The HVAC equipment room 2153 that contains the CCW tanks, the control room ventilation normal ventilation components including the chillers, etc. It was verified that a failure in this room would not affect safety-related equipment.

  • The main chiller room 2092 was walked down and verified not to contain any safety-related equipment.

7/2/03 Ted Ivy and Stan Batch walked down:

  • Verified no SR components adjacent to NSR components in the PASS Building.
  • Verified the SFP heat exchanger, filters, ion exchanger tank and pumps are in their own rooms.
  • Verified the Boric Acid evaporators themselves are not used and located in their own rooms.
  • Verified waste gas compressor coolers (2E-10AB; 2E-102A, B; 2E-103A, B) are not located adjacent to safety-related equipment. (They are located in rooms for the compressors.)
  • Verified 2VUC-21 (cooled by ACW) is in an electrical equipment area containing NSR equipment and its failure could not affect SR equipment
  • Verified sample coolers 2E31 and 2E51 are in a hallway and their failure cannot affect SR equipment Verified bv n
