1 Introduction The U.S. Nuclear Regulatory Commission (NRC or the staff) conducted a 10-day audit at the Fermi 2 Nuclear Power Plant (Fermi 2), in Newport, MI, from September 15 to October 3, 2014. | |||
The purpose of the audit was to examine DTE Electric Companys (DTE or the applicant) aging management programs (AMPs) and related documentation to verify the applicants claims of consistency with the corresponding AMPs in NUREG-1801, Revision 2, Generic Aging Lessons Learned (GALL) Report, dated December 2010. As described in the GALL Report, the staff based its evaluation of the adequacy of each AMP on its review of the following 10 program elements in each AMP: (1) scope of the program; (2) preventive actions; (3) parameters monitored or inspected; (4) detection of aging effects; (5) monitoring and trending; (6) acceptance criteria; (7) corrective actions; (8) confirmation process; (9) administrative controls; and (10) operating experience. | |||
Exceptions to the GALL Report AMP elements will be evaluated separately as part of the staffs review of the Fermi 2 license renewal application (LRA) and documented in the staffs safety evaluation report (SER). | |||
NUREG-1800, Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants (SRP-LR), Revision 2, dated December 2010, provides staff guidance for reviewing an LRA. The SRP-LR allows an applicant to reference in its LRA the AMPs described in the GALL Report. By referencing the GALL Report AMPs, the applicant concludes that its AMPs correspond to those AMPs reviewed and approved in the GALL Report and that no further staff review is required. If an applicant credits an AMP for being consistent with a GALL Report program, it is incumbent on the applicant to ensure that the plant program contains all of the elements of the referenced GALL Report program. The applicants determination should be documented in an auditable form and maintained onsite. | |||
During the audit, the staff audited AMP elements 1 - 6 and 10 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, acceptance criteria, and operating experience). These elements of the applicants AMPs were claimed to be consistent with the GALL Report and were audited against the related elements of the associated AMP described in the GALL Report, unless otherwise indicated in this audit report. Elements 7 - 9 (corrective actions, confirmation process, and administrative controls) were audited during the scoping and screening methodology audit conducted on August 4 - 7, 2014, and are evaluated separately. The staff audited all AMPs that the applicant stated were consistent with the GALL Report AMPs. | |||
During the audit, if the applicant took credit for a program in the GALL Report, the staff verified that the plant program contained all the elements of the referenced GALL Report program. | During the audit, if the applicant took credit for a program in the GALL Report, the staff verified that the plant program contained all the elements of the referenced GALL Report program. | ||
In addition, the staff verified the conditions at the plant were bounded by the conditions for which the GALL Report program was evaluated. | In addition, the staff verified the conditions at the plant were bounded by the conditions for which the GALL Report program was evaluated. | ||
In addition to auditing AMP elements 1 through 6 and 10, the staff also reviewed documentation associated with the following aging management review (AMR) items: (1) LRA Table 3.3.2-6, Compressed Air Systems, (2) LRA Table 3.3.2-12, Control Center Heating, Ventilation and Air Conditioning System, and (3) LRA Table 3.4.2-3-7, Circulating Water System, Nonsafety-Related Components Affecting Safety-Related Systems. The activities and observations associated with these AMR items are documented at the end of this report. | |||
In addition to auditing AMP elements 1 through 6 and 10, the staff also reviewed documentation associated with the following aging management review (AMR) items: | |||
Relevant Documents Reviewed Document Title Revision / Date 1.FERMI-RPT-12-LRD03 | 2 In performing the audit, the staff examined the applicants LRA, program-bases documents, and related references; interviewed various applicant representatives; and conducted walkdowns of several plant areas. In total, 44 AMPs were reviewed and 41 breakout (discussion) sessions with applicant representatives were conducted. This report documents the staffs activities during the audit. | ||
LRA AMP B.1.1, Aboveground Metallic Tanks Summary of Information in the Application. The LRA states that AMP B.1.1, Aboveground Metallic Tanks, is a new program that will be consistent with the program elements in GALL Report AMP XI.M29, Aboveground Metallic Tanks, as modified by License Renewal Interim Staff Guidance (LR-ISG)-2012-02, Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion under Insulation. To verify this claim of consistency, the staff audited the LRA AMP. At the time of the audit, the applicant had not yet fully developed the documents necessary to implement this new program, and the staffs audit addressed only the program elements described in the applicants basis document and applicable plant-specific operating experience. Issues identified but not resolved in this report will be addressed in the SER. | |||
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff conducted walkdowns of the combustion turbine generator (CTG) fuel oil tank and condensate storage tank (CST). The staff also conducted an independent search of the applicants operating experience database using the keywords: tank, inspect and insulation. | |||
The table below lists the documents that were reviewed by the staff and were found relevant to the audit. These documents were provided by the applicant or were identified in the staffs search of the applicants operating experience database. | |||

Drawing 5M721-5922 Revision A Cone Roof and Shell Layout During the audit of program elements one through six, the staff verified that the scope of program, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. For the preventive actions program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing a request for additional information (RAI) for the subject discussed below. | |||
* The preventive actions program element of the LRA AMP states that [i]n accordance with installation and design specifications, the tanks do not employ caulking or sealant at the concrete/tank interface. The GALL Report AMP recommends that sealant or caulking be applied to outdoor tanks at the external interface between the tank and concrete foundation. The function of the sealant or caulk is to minimize the amount of water and moisture penetrating the interface between the tank and concrete foundation. | |||
The GALL Report AMP further states that sealant or caulking are not necessary if the configuration of both the tank bottom and foundation is sloped in such a way that water cannot accumulate. | |||
It is not clear to the staff that these statements are consistent for the CST. The design of the CST foundation is a concrete ring with the tank bottom in contact with graded sand. The design also incorporates drains to facilitate the removal of water from the interior of the concrete ring foundation. However, the top surface of the concrete ring is not sloped to prevent water and moisture intrusion at the outside interface of the ring foundation. The accumulation of water or moisture at the outside interface of the ring foundation could result in the loss of material or cracking of the aluminum. | |||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing an RAI for the subject discussed below. | |||
* During the review of the past 10-years of applicable operating experience it was noted that there have been multiple instances of degradation of the insulation and jacketing on the roof of the CST, including separations in the sheet metal seams, loss of flashing, and loss of insulation due to weather. In 2013 the CST roof insulation was completely | |||
4 removed and pre-fabricated insulation was installed. The as-found condition of the aluminum roof was not documented in the work order. The aluminum roof has been exposed to weather on multiple occasions and it is unclear if there is any age-related degradation under the pre-fabricated insulation. | |||
The staff also audited the description of the LRA AMP provided in the updated final safety analysis report (UFSAR) supplement. The staff found that sufficient information was not available to determine whether the description provided in the UFSAR supplement was an adequate description of the LRA AMP. In order to obtain the information necessary to verify the sufficiency of the UFSAR supplement program description, the staff will consider issuing an RAI for the subject discussed below. | The staff also audited the description of the LRA AMP provided in the updated final safety analysis report (UFSAR) supplement.

The implementation schedule for this commitment is [p]rior to September 20, 2024, or the end of the last refueling outage prior to March 20, 2025. LR-ISG-2012-02, Table 3.0-1, recommends that the program be implemented 10 years prior to the period of extended operation. The recommendation to implement the program 10 years prior to the period of extended operation is to support the inspection guidance provided in LR-ISG-2012-02, Table 4a, Tank Inspection Recommendations. The guidance provided in Table 4a includes inspections of all tank interior and exterior surfaces, including tank tops and bottoms, in timeframes ranging from within 5 to 10 years prior to the period of extended operation. | ||
Audit Results. Based on this audit, the staff verified that the scope of program, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M29. The staff also identified certain aspects of the preventive actions program element of the LRA AMP for which additional information or evaluation is required before consistency can be determined. | |||
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. The staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. | |||
In addition, the staff identified a need for additional information regarding the adequacy of the program description in the UFSAR supplement. | |||
LRA AMP B.1.2, Bolting Integrity Summary of Information in the Application. The LRA states that AMP B.1.2, Bolting Integrity, is an existing program with enhancements and an exception that is consistent with the program elements in GALL Report AMP XI.M18, Bolting Integrity. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP. The exception to the GALL Report AMP not necessary for consistency with the GALL Report is evaluated in the SER. | |||
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff conducted walkdowns of the turbine building, reactor building, and the residual heat removal (RHR) complex. The staff also | |||
5 conducted an independent search of the applicants operating experience database using the keywords: bolt, torque, preload, crack, leak, corrosion, and seal cap. | |||

Aspects of the detection of aging effects program element of the LRA AMP associated with the exception were not evaluated during this audit. Aspects of this program element that are not associated with the exception were evaluated and are described below. | |||
During the audit, the staff verified that the preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. The staff noted that aspects of the detection of aging effects program element not associated with the exception are not consistent with the corresponding program element in the GALL Report AMP. | |||
The staffs evaluation of aspects of the detection of aging effects program element associated with the exception will be addressed in the SER. In addition, the staff found that for the scope of program program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* LRA Section B.1.2 states that the Bolting Integrity Program manages loss of preload, cracking, and loss of material for accessible closure bolting for safety-related and nonsafety-related pressure components. GALL Report AMP XI.M18 scope of program program element states that the program manages aging of closure bolting for pressure retaining components within the scope of license renewal, including both safety-related and non-safety-related bolting. The GALL Report AMP also recommends periodic inspections of closure bolting be performed at least once per refueling cycle for signs of leakage to ensure the detection of age-related degradation due to loss of material and loss of preload. It is not clear to the staff whether all pressure-retaining closure bolting (both accessible and inaccessible) within the scope of license renewal is managed for age-related degradation. In addition, if inaccessible bolting is managed differently, the | |||
7 staff is not clear as to the applicants criteria for considering bolting inaccessible. The staff needs this information to determine whether the effects of aging will be managed consistent with the recommendations in the GALL Report AMP. | |||
* LRA Section B.1.2 states an enhancement to the Bolting Integrity Program to revise the procedures to inspect the residual heat removal service water (RHRSW), emergency equipment service water (EESW), and emergency diesel generator service water system pump and valve bolting submerged in the RHRSW reservoir at least once per refueling outage. GALL Report AMP XI.M18 detection of aging effects program element recommends periodic inspections (at least once per refueling cycle) of closure bolting for signs of leakage to ensure the detection of age-related degradation due to loss of material and loss of preload. The staff reviewed the program basis documents and was not clear how the submerged closure bolting will be inspected such that loss of material and loss of preload can be detected prior to loss of intended function consistent with the GALL Report AMP detection of aging effects program element. | |||
During the audit the staff performed a database search of Fermi 2 operating experience and found no results for the keyword seal cap associated to their installation for closure bolting at Fermi 2. | |||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. The staff also determined that the operating experience provided by the applicant and identified by the staffs independent database search is not sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage the effects of aging. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing an RAI for the subject discussed below. | |||
* The LRA states that [p]lant procedures prohibit the use of lubricants containing molybdenum disulfide. The GALL Report AMP states that molybdenum disulfide should not be used as a lubricant due to its potential contribution to stress corrosion cracking (SCC), especially for high-strength bolts. During the audit the staff was able to confirm that plant procedures prohibit the use of molybdenum disulfide lubricants; however, it is not clear whether molybdenum disulfide lubricants have been used at Fermi 2 before plant procedures were revised to prohibit their use. If these lubricants have been used in the past, the staff needs additional information regarding how the program will manage aging of closure bolts lubricated with molybdenum disulfide. | |||
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR. | |||
Audit Results. Based on this audit, the staff verified that the preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M18. The staffs evaluation of aspects of the detection of aging effects program element associated with exceptions will be addressed in the SER. The staff also identified certain aspects of the scope of program and detection of aging effects program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined. | |||

12 GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. For the detection of aging effects and acceptance criteria program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of GALL Report AMP XI.M41, as modified by LR-ISG-2011-03, the staff will consider issuing RAIs for the subjects discussed below. | |||
* The detection of aging effects program element of the LRA AMP states that buried piping inspections will be conducted in a manner consistent with those in the detection of aging effects element of GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. | |||
During the staffs review of buried pipe inspection reports, it was noted that the coatings for two excavated pipe inspections were classified as being in fair condition. However, the reports for the two inspections state that coating holidays ranging in size from 2 in2 to 10 in2 for one pipe and 30 in2 to 95 in2 for the other pipe were detected. The classification of the coating condition may not be consistent with LR-ISG-2011-03 Table 4a, Inspections of Buried Pipe, footnote 2, which states that inspection category E, opposed to F (category E has a lower number of inspections relative to F), | |||
may be used if there is no significant coating degradation. The staff lacks sufficient information to conclude that, given the size of the holidays reported; the coating condition is appropriately classified as fair rather than significantly degraded. As a result of classifying the coatings as being in fair condition, the number of inspections conducted may not be consistent with the detection of aging effects program element of GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. | |||
* The acceptance criteria program element of the LRA AMP states that the program activities associated with the acceptance criteria are consistent with GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. The GALL Report AMP recommends that if a 100 millivolt (mV) polarization criterion is used to assess the performance of the cathodic protection system, the LRA should include the basis for why adequate protection is provided for steel components exposed to a mixed potential environment. | |||
The applicants acceptance criteria for the cathodic protection system includes negative 0.85 volts and 100 mV of cathodic polarization. The applicants acceptance criteria also includes an allowance for polarization potentials less negative than 0.85 volts if the buried components are in high resistivity soils that are well drained and well aerated. | |||
The applicant did not provide the basis for the acceptance criterion of the cathodic protection system. | |||

During the audit of program elements one through six, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. For the detection of aging effects program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* The LRA states that the BWR Stress Corrosion Cracking Program is consistent with GALL Report AMP XI.M7, with no exceptions. The detection of aging effects program element of the GALL Report AMP states that the extent and schedule of the inspection are described in NRC Generic Letter (GL) 88-01 and may be modified in accordance with Boiling-Water Reactor Vessel and Internals Project (BWRVIP)-75-A. The staff noted that the applicants Category A welds are subsumed in the applicants risk-informed inservice inspection. The staff also noted that the percentage of Category A welds to be inspected by the applicant is not stated in the LRA. It is unclear to the staff if the extent and schedule of the inspection are consistent with GL 88-01 and BWRVIP-75-A. | |||
* The aging management review tables for the condensate and feedwater systems in the LRA do not include AMR items to manage IGSCC for Category D welds, which were identified in the 1992 communications between the Detroit Edison Company and the NRC (letters dated July 29, 1992, and December 18, 1992, referenced in the document table above). The staff cannot determine the adequacy of the applicants program and AMR results without additional information to justify the omission of relevant AMR items. | |||
* The staff also noted that the 1992 communications (letters dated July 29, 1992, and December 18, 1992, referenced in the document table above) indicate that the applicants Category D welds are located outboard of the containment isolation valves and at least 10 percent of these welds should be inspected during each refueling outage. The staff further noted that the extent and frequency of these inspections are different from the inspection guidelines provided in GL 88-01 and BWRVIP-75-A. | |||
: | BWRVIP-75-A states that in the case of the implementation of hydrogen water chemistry 100 percent of Category D welds should be inspected every 10 years and at least 50 percent of these welds should be inspected in the first 6 years. However, the LRA does not identify this difference as a program exception. The staff finds that additional information is necessary to clarify why this difference is not identified as a program exception and to confirm whether this difference is acceptable for adequate aging management. | ||
22 During the audit of the operating experience program element, the staff found a need to confirm whether the plant-specific operating experience regarding condenser inleakage affects the sufficiency of the LRA program. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subject discussed below. | |||
* The staff noted that CARD 11-21607 states that during the startup on February 10, 2011, the applicants plant was shut down due to main condenser tube inleakage and associated water chemistry excursions. CARD 11-21607 also indicates that inspections of all condenser water boxes identified the ejection of tube plugs from receptive condenser tubes. The ingress of chloride, sulfate, and other contaminants into the reactor coolant system, due to main condenser inleakage, can promote IGSCC in BWR piping and piping welds. However, LRA Section B.1.8 and the onsite program evaluation report for the applicants program do not clearly address the potential impact of condenser cooling water inleakage on the effectiveness of the applicants program. | |||
The staff finds that additional information is necessary to confirm that the applicants assessment of operating experience regarding condenser inleakage ensures the effectiveness of the applicants program. | |||
The staff also audited the description of the LRA AMP provided in the UFSAR supplement.

During the audit, the staff verified that the preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the scope of program program element, insufficient information was available to determine if they were consistent with the corresponding program elements of the GALL Report AMP. To obtain the information necessary to verify if these program elements are consistent with the corresponding program elements of the GALL Report, the staff will consider issuing an RAI for the subjects discussed below. | |||
* The scope of program program element of the GALL Report AMP includes BWRVIP-58-A as guidelines for the repair design criteria for the control rod drive housing and BWRVIP-57-A as the guidelines for the repair design criteria for the lower plenum components. The applicant references these documents as the repair design criteria guidelines for these components as well as BWRVIP-55-A; however, the plant procedures only reference BWRVIP-55-A. The staff is unclear if the applicant is using any BWRVIP guidelines beyond those in the GALL Report AMP. | |||
* The scope of program program element of the GALL Report AMP includes BWRVIP guidelines for which the BWR vessel internal components are subject and which may contain applicant action items. The applicant responded to these BWRVIP applicant action items in LRA Appendix C. The staff is unclear if LRA Appendix C includes the accurate list of BWRVIP guidelines actually used at Fermi 2 or if the responses to the applicant action items considered the recently approved measurement uncertainty recapture power uprate. | |||
During the audit of the operating experience program element, the staff determined that the operating experience provided by the applicant and identified by the staffs independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff).

The staff conducted its audit of LRA program elements one through seven based on the contents of the existing program as modified by the proposed enhancements. The staff notes that the scope of the audit covered the additional program element 7 corrective actions because the applicant included an enhancement for this element to establish consistency with the recommended actions in the corresponding element of the GALL Report AMP XI.S1 that is specific to the potential case if moisture is detected or suspected in the inaccessible area on the exterior of Mark I containment drywell shell. | |||
During the audit, the staff verified that the scope of program, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and corrective actions program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* The preventive actions program element of GALL Report AMP XI.S1 recommends preventive actions in accordance with Research Council for Structural Connections publication for structural bolting consisting of American Society for Testing and Materials (ASTM) A325, ASTM F1852, and ASTM A490 bolts. The staff noted that the corresponding element, with enhancements, of the LRA AMP basis document (FERMI-RPT-12-LRD05, Revision 1) addresses ASTM A325 and A490 bolting, but made no mention of ASTM F1852 bolting. It is not clear to the staff that the above mentioned program element of the LRA AMP is consistent with the recommendations in the GALL Report AMP because there was no mention of ASTM F1852 bolting. Note that this is a common issue across B.1.12 Containment Inservice Inspection - IWE, B.1.22 Inservice Inspection - IWF, and B.1.42 Structures Monitoring AMPs. | |||
* The detection of aging effects program element of GALL Report AMP XI.S1 recommends that the program be augmented to require surface examination, in addition to visual examination, to detect cracking in stainless steel penetration sleeves, bellows, dissimilar metal welds, and steel components that are subject to cyclic loading but have no current licensing basis fatigue analysis. The GALL Report AMP also states that where feasible, appropriate Appendix J tests may be performed in lieu of surface examination. The LRA AMP program basis document states that the above mentioned components are monitored for cracking. It also states that, additionally, XI.S4 Containment Leak Rate Program tests may be performed in lieu of surface examination. | |||
31 It is not clear to the staff that these statements are consistent because the LRA AMP basis document does not state that to detect cracking supplemental surface examination will be performed on the subject components, in addition to visual examination. Further, it does not identify the specific components for which the option to perform Appendix J tests, in lieu of surface examination, will be used and the type of Appendix J test that would be performed in order for staff to evaluate the appropriateness of the test to detect cracking in these components prior to loss of intended function. | |||
* The preventive action program element of GALL Report AMP XI.S1 recommends that the program be augmented to include preventive actions that ensure that moisture levels associated with an accelerated corrosion rate do not exist in the exterior portion of the BWR Mark I steel containment drywell shell. The actions consist of ensuring that the sand pocket area drains and/or the refueling seal drains are clear. The parameters monitored or inspected program element of the GALL Report AMP recommends that applicants with BWR Mark I steel containments should monitor sand pocket area drains and/or the refueling seal drains for water leakage. The licensees should ensure the drain lines are clear to prevent moisture levels associated with accelerated corrosion rates in the exterior portion of the drywell shell. The preventive action program element of the LRA AMP includes an enhancement to revise plant procedures to require inspection of the sand pocket drain lines prior to the period of extended operation. Also, the parameters monitored or inspected program element of the LRA AMP includes an enhancement to revise plant procedures to specify that inspections of sand pocket drain lines will monitor the internal condition of drain lines. Further, the detection of aging effects program element of the LRA AMP includes an enhancement to revise plant procedures to require visual inspection of sand pocket drain lines to ensure there is no evidence of blockage. Based on item 9 of LRA Section A.4, License Renewal Commitment List, these enhancements (i.e., Commitments No. 9a, 9d and 9e) are scheduled to be completed prior to the period of extended operation. The staff needs additional information to determine that these enhancements are consistent with the recommendations for BWR Mark I steel containments in the preventive actions and parameters monitored or inspected program elements of the GALL Report AMP because: (i) it is not clear if the intent of the license renewal commitments is to revise plant procedures prior to the period of extended operation or to revise plant procedures and perform inspections of drain lines prior to the period of extended operation; (ii) the proposed enhancements (i.e., Commitments No. 9a and 9d) do not provide a stated objective for the inspection (i.e., to ensure that drain lines are clear or to monitor for water leakage or moisture in the drains or both; based on description in the above mentioned program elements, they appear to be exclusively intended to ensure that sand pocket drain lines are clear); and (iii) the enhancements (i.e., Commitments No. 9a, 9d, and 9e) do not provide the associated frequency of inspections and the basis for its adequacy to meet the intended objective; and (iv) it is not clear to the staff as to how the LRA AMP ensures that the refueling seal drains are clear. | |||
* The preventive actions program element of the LRA AMP basis document states on page 26 that: | |||
During refueling the refueling bellows drain empties into a manifold which is equipped with a sight glass. This sight glass is monitored when the refueling pool is flooded to detect potential leakage of water into the space around the drywell shell. The sand pocket drains are also [to] be monitored for signs of moisture. Fermi 2 plans to re-inspect the drain lines to verify their condition prior to the period of extended operation to confirm that these preventative actions | |||
32 are not warranted. The program will be enhanced to require inspection of the sand pocket drain lines prior to the period of extended operation. (emphasis added) | |||
Further, the parameters monitored or inspected program element on page 28 of the program basis document states that: Fermi 2 performs routine surveillances of the drains to record the observed condition of the drain lines for any leakage. Fermi 2 will inspect the sand pocket drain lines to verify their condition prior to the period of extended operation to confirm that the sand pocket drains are clear in ... | |||
The parameters monitored or inspected program element of GALL Report AMP XI.S1 recommends that license renewal applicants with BWR Mark I steel containments should [periodically] monitor the sand pocket area drains and/or the refueling seal drains for water leakage. | |||
During the audit, the staff reviewed Fermi 2 Surveillance Procedure 24.000.03, Revision 77 (including Attachments 1 and 2), and noted that the procedure includes the following regulatory commitments made by letter NRC-88-0081, Revised Response to GL 87-05, dated 4/20/88, and tracked in the applicants Regulatory Action Commitment Tracking System (RACTS) under RACTS 88027. These items require inspection of the reactor-drywell seal bellows and the four sand cushion drain lines for leakage during every refueling outage. | |||
(a) Items (35.0 in Attachment 1 and 1.10 in Attachment 2 identified as commitments | |||
[CM]) requiring verification that reactor-drywell seal bellows leakage is within limits. | |||
The procedure requires this verification to be performed during Mode 5 Refueling on a daily basis for the first 3 days following reactor cavity flooding and at a frequency of 7 days following that with an acceptance criteria of no observed leakage; (b) Item (1.09 in Attachment 2 identified as commitment [CM]) requiring verification that drywell sand cushion leakage is within limits. The procedure requires this verification to be performed during Mode 5 Refueling at a frequency of 7 days (with a note that the commitment is monthly but performance will be 7 days) following reactor cavity flooding with an acceptance criteria of no observed leakage. Checks for leakage are required at Azimuth 90/180/270/360 6 below reactor pedestal catwalk between torus and drywell. | |||
Despite the above existing commitments controlled by Procedure 24.000.03 to periodically monitor the sand pocket cushion drain lines and reactor-drywell seal bellows for signs of water leakage into inaccessible areas of the drywell, it is not clear to the staff if these periodic monitoring of the sand cushion drain lines and refueling seal bellows for water leakage every refueling outage will continue into the period of extended operation because of the inconsistent and contradicting statement (cited with emphasis added in the indented paragraph at the beginning of the bullet for this issue) on page 26 of the program basis document. Therefore, the staff needs additional information to determine if the parameters monitored or inspected program element is consistent with the GALL Report AMP with regard to the recommendation for periodically monitoring the sand pocket area drains and the refueling seal drains for water leakage. | |||
* The monitoring and trending program element of the LRA AMP included the enhancement, Revise plant procedures to determine drywell shell thickness in the sand pocket areas before the period of extended operation. From the results, develop a corrosion rate to demonstrate that the drywell shell will have sufficient thickness to perform its intended function through the period of extended operation. The | |||
added) Further, the | |||
The procedure requires this verification to be performed during Mode 5 | |||
* The | |||
33 corresponding program element in GALL Report AMP XI.S1 recommends that the applicant develop a corrosion rate that can be inferred from past ultrasonic testing (UT) examinations or establish a corrosion rate using representative alternate means and provide a technical basis based on the developed or established corrosion rate that the drywell will have sufficient thickness to perform its intended function through the period of extended operation. During the audit, the staff noted that, for reasons indicated in the letters NRC-87-005 and NRC-88-0081, dated September 10, 1987, and April 20, 1988, respectively, ultrasonic thickness measurements of the drywell shell sand pocket areas were not performed at Fermi 2 in response to Generic Letter 87-05. It is not clear to the staff if these statements are consistent because the proposed enhancement in the LRA AMP program basis does not indicate the minimum number of sets and interval at which UT measurements will be performed, and does not provide the technical basis of how an appropriate corrosion rate will be developed if only one set of UT measurements is intended. | |||
* The corrective actions program element of the LRA AMP included an enhancement to revise plant procedures to require three specific corrective actions should moisture be detected or suspected in the inaccessible area on the exterior of the Mark I steel containment drywell shell. The staff noted that the specific actions included in the above enhancement to the LRA AMP correspond to recommended actions (b), (c), and (d) in the corrective actions program element of GALL Report AMP XI.S1 if moisture has been detected in the inaccessible area on the exterior of the Mark I containment drywell shell or the source of moisture cannot be determined subsequent to root cause analysis. | |||
However, the LRA AMP program basis document and corresponding enhancement did not address action (a) of the GALL Report AMP which recommends including in the scope of license renewal any components that are identified as a source of moisture, if applicable, and performing aging management review. It is not clear to the staff that the corrective actions program element of the LRA AMP is consistent with recommended actions in the GALL Report AMP specifically applicable to inaccessible areas of the drywell shell exterior of Mark I containments because the LRA AMP basis document did not identify the components that are potential sources of moisture to inaccessible areas of the drywell exterior and whether they were subjected to AMR. | |||
During the audit, the staff made the following observations: | During the audit, the staff made the following observations: | ||
* The staff reviewed the ISI-NDE Program Plan for Fermi 2, Part F, | * The staff reviewed the ISI-NDE Program Plan for Fermi 2, Part F, ASME Section XI Containment Inservice Inspection Program, Appendix F4.5, and noted that Fermi 2 has a proactive inspection program of the interior wetted surfaces of submerged areas of the torus and the vent header. The interior of the torus is inspected and repaired on an every other refueling outage basis. During these examinations, the submerged areas of the torus shell are cleaned from water line to water line to remove sludge and other foreign material, and then coating inspectors inspect the entire area by VT-3 visual inspection. All areas of broken blisters and mechanical damage exhibiting corrosion on the pressure boundary immersion area are repaired. Additionally, Fermi 2 monitors the blister condition on specific immersed areas of the torus chosen based on their relatively high number of indications. During each inspection, the size, population density and condition of the blisters are monitored and trended to identify and evaluate adverse trends. | ||

by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR. | 41 The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements. | ||
During the audit, the staff verified that the scope of program, preventive actions, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP, as modified by LR-ISG-2011-03 and LR-ISG-2012-02. However, the staff found that, for the parameters monitored or inspected and detection of aging effects program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* The parameters monitored or inspected and detection of aging effects program elements of the LRA AMP include an enhancement to revise program procedures to ensure that walkdowns will include inspections for leakage to detect cracking in stainless steel components exposed to air containing halides. However, some of the subject components have a gaseous internal environment. It is not clear to the staff how external leakage of the gas will be detected. | |||
* LR-ISG-2012-02 revised GALL Report AMP XI.M36 to recommend inspections of thermal insulation when the insulation has a function to reduce heat transfer. The LRA AMP does not contain this activity. The applicants program basis document, FERMI-RPT-12-LRD03, states that thermal insulation is not credited for reduction of heat transfer. However, LRA Table 3.5.2-4 includes an AMR item for insulation with an intended function of heat transfer reduction, and the Structures Monitoring Program is proposed to manage loss of material and change in material properties. It is not clear to the staff whether the activities to inspect thermal insulation under the Structures Monitoring Program are consistent with those recommended in LR-ISG-2012-02. | |||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. | |||
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR, as modified by LR-ISG-2012-02. | |||

The staff conducted its audit of LRA program elements one through six based on the contents of the existing program, as modified by the proposed enhancements. Aspects of the corrective actions program element of the LRA AMP associated with the exception were not evaluated during this audit. Aspects of this program element that are not associated with the exception were evaluated and are described below. | |||
Report AMP. | 43 During the audit, the staff verified that the scope of program, preventive actions, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. The staff also verified that aspects of the corrective actions program element not associated with the exception are consistent with the corresponding program elements in the GALL Report AMP. | ||
The staffs evaluation of aspects of the program element associated with the exception will be addressed in the SER. In addition, the staff found that for the parameters monitored or inspected program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subject discussed below. | |||
The | * The parameters monitored or inspected program element of the LRA AMP states that the cycle counting method of fatigue monitoring will be used to track the number of occurrences for plant transients. The GALL Report AMP recommends tracking the number of each plant transient, although it does not provide guidance on the use of a specific fatigue monitoring method. The applicants Fatigue Monitoring Program is currently limited to cycle counting and does not allow for more detailed fatigue monitoring methods, such as Cycle-Based Fatigue and Stress-Based Fatigue, to prevent the fatigue design limit from being exceeded. It is not clear to the staff if fatigue monitoring methods other than Cycle Counting are being used to prevent the fatigue design limit of components from being exceeded. | ||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. The staff also noted that the applicant tracks cumulative operating time on components in support of flaw evaluations. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subject discussed below. | |||
* The applicants Fatigue Monitoring Program is limited to monitoring plant transients in order to remain below component design limits based on crack initiation. The applicant is currently tracking cumulative operating time on components in support of flaw evaluations. The applicants Fatigue Monitoring Program does not track usage time or support crack growth calculations. It is unclear if the TLAAs associated with these components can be tracked using the Fatigue Monitoring Program. | |||
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified that this description is consistent with the description provided in the SRP-LR, although information regarding the methodologies to implement the commitments was not available for review. In order to obtain the information necessary to verify the sufficiency of the UFSAR supplement commitments, the staff will consider issuing RAIs for the subject discussed below. | |||
* The applicants Fatigue Monitoring Program contains enhancements to prevent the fatigue design limit of components from being exceeded when accounting for environmental effects. The UFSAR supplement contains a commitment (Commitment No. 12, part b) to calculate environmental correction factors in order to assess the impact of the reactor coolant environment on component fatigue life. As part of this | |||
44 commitment, plant-specific component locations in the reactor coolant pressure boundary that lead the components identified in NUREG/CR-6260 will be identified for tracking purposes. It is unclear what methodology is being used to identify the plant-specific limiting locations. | |||
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, detection of aging effects, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP X.M1. | |||
The staff also verified that for the acceptance criteria program element, the aspects of the LRA AMP program element not associated with the exception are consistent with the corresponding program element in GALL Report AMP X.M1. The staffs evaluation of aspects of the program element associated with exceptions will be addressed in the SER. The staff also identified certain aspects of the parameters monitored or inspected program element of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined. | |||
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. However, the sufficiency of the AMP to track parameters other than transients, such as cumulative operating time, may require additional information. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR, although additional information regarding the methodologies being used to satisfy the aspects of the associated commitments may be requested. | |||
LRA AMP B.1.18, Fire Protection Summary of Information in the Application. The LRA states that AMP B.1.18, Fire Protection, is an existing program with enhancements that is consistent with the program elements in GALL Report AMP XI.M26, Fire Protection. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP; however, it does not consider the sufficiency of enhancements which are not necessary for consistency, which will be evaluated in the SER. | |||

During the audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. | |||
However, the staff found that for the detection of aging effects program element, additional information is necessary in order for the staff to complete its review; the staff will consider issuing RAIs for the subject discussed below. | |||
* The staff noticed that the Aging Management Program Evaluation Report for Fire Protection, under the comparison statement for the Detection of Aging Effects program element, states that visual inspection of other fire barrier materials, including fire barrier dampers, is performed at a frequency in accordance with the technical requirements manual, which is every 18 months. | |||
Consistent with the SRP-LR and the GALL Report, DTE selected the Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program and the External Surfaces Monitoring Program to manage for loss of material. The periodicity for the Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program is based on a sampling of at least 20 percent or maximum of 25 components every 10 years. Selection of the Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program may conflict with DTEs current requirement to inspect the fire damper housings every 18 months. | |||
47 During the audit, the staff made the following observations: | |||
* In Section 4.6 of FERMI-RPT-12-LRD03, under the Detection of Aging Effects element, it states that If any sign of degradation is detected within that sample, the scope of the inspection is expanded to include additional seals. This statement is consistent with the statement in GALL Report AMP XI.M26 for expansion of the sample. The staff noticed that Technical Requirements Manual (TRM) Section 3.12.8 (Technical Requirements Surveillance Requirement (TRSR) 3.12.8.7) states that if apparent changes in appearance or abnormal degradations are found, a visual inspection of an additional 10 percent of each type of sealed penetration shall be made, and that this inspection process shall continue until a 10 percent sample with no apparent changes in appearance or abnormal degradation is found. To show consistency with the GALL Report for this particular activity, DTE references Plant Technical Procedure - Fermi 2 28.507.05, Revision 19, Inspection of Penetration Fire Stops. General Requirement 5.1.1 states, in part, If changes in appearance from normal are found, a visual inspection of an additional 10 percent of that type of sealed penetration shall be made. | |||
This inspection process shall continue until a 10 percent sample is found with no apparent changes in appearance or abnormal degradation. | |||
* Enhancement No. 2 states that Fire Protection Program procedures will be revised to require visual inspections of in-scope fire wrap and fire stop materials constructed of fibersil cloth, cerafoam, kaowool, thermolag, flamemastic, and pyrocrete. The staff noticed that LRA Table 3.5.2-4 does not include cerafoam, kaowool, flamemastic or pyrocrete as materials. However, FERMI-RPT-12-AMC04 states that [m]aterial used for fire stops and fire wraps include carborundum durablankets, carborundum fibersil cloth, silicone fabric boot, silicone elastomers and steel. It is not clear if the applicant uses cerafoam, kaowool, flamemastic or pyrocrete in the plant as fire stop materials. | |||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. | |||
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR. | |||
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M26. The staff also identified certain aspects of the detection of aging effects program element of the LRA AMP for which additional information or additional evaluation is required before the staff can complete its review. | |||
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated.

WO 38192166 04/22/2014 Test for Main Transformer 2B The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements. Aspects of the detection of aging effects program element of the LRA AMP associated with the exceptions were evaluated during this audit. Aspects of the program elements that are not associated with the exceptions were evaluated and are described below. | |||
50 During the audit, the staff verified that the scope of program, preventive actions, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. The staff also verified that aspects of the detection of aging effects program element not associated with the exceptions are consistent with the corresponding program elements in the GALL Report AMP. The staffs evaluation of aspects of this program element associated with the exceptions will be addressed in the SER. | |||
In addition, the staff found that for the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* Enhancement Nos. 2 and 7 to the parameters monitored or inspected and detection of aging effects program elements of the LRA AMP state that an inspection of the wet fire water system piping condition will be conducted at least once every 5 years. The applicant will conduct the test by opening a flushing connection at the end of one main and by removing a sprinkler toward the end of one branch line. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in National Fire Protection Association (NFPA) 25 Section 14.2.2, the licensee inspect every other system in buildings with multiple wet pipe systems every 5 years. During the audit, the applicant confirmed that it has multiple wet pipe systems in buildings with in-scope components protected by the fire water system. The applicant did not provide a basis for why testing only one system every 5 years is sufficient. | |||
* Enhancement No. 4 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that a basis for the acceptance criteria of less than or equal to 25 pounds per square inch gauge (psig) and less than or equal to 10 psig that currently exists in the main drain test procedures will be developed. | |||
LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Section 13.2.5.2, a 10 percent reduction on full flow pressure during main drain tests should be corrected. | |||

* Enhancement No. 6 to the | * Enhancement No. 6 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that sprinklers will be cleaned if obstructions are identified during internal inspections. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Section 5.2.1.1.2, licensee should replace corroded or loaded sprinklers. The applicant did not provide a basis for why corroded or loaded sprinklers can be cleaned versus replaced. | ||
* Enhancement No. 11 to the | * Enhancement No. 11 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that an obstruction investigation will be conducted after an extended shutdown of more than one year. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Sections 14.2.1.3 and 14.3.1, there are additional criteria for conducting obstruction investigations (e.g., discharge of obstructive material during routine water tests, plugging of inspectors test connection, pinhole leaks). During the audit, the staff did not find any procedures that included the additional criteria, nor did the applicant provide a basis for why its enhancement is sufficient to ensure that obstruction investigations would be conducted when | ||

It is not clear to the staff that these statements are consistent because only one criterion to conduct an obstruction investigation is identified. | ||
* The | * Exception No. 7 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that a one-time inspection of the internal surfaces of the dry piping downstream of the manual isolation valve for the wet pipe system in the cable spreading room will be conducted. LR-ISG-2012-02 AMP XI.M27 recommends that a licensee should conduct periodic inspections of fire water system piping exposed to indoor air (see LRA Table 3.3.2-7). It is not clear to the staff that these statements are consistent because the applicant did not provide a basis for why there is reasonable assurance that the current licensing basis intended function(s) of the piping would be met when only a one-time inspection is conducted. | ||
* Exception No. 7 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that in lieu of conducting a deluge test with air or smoke for the control center heating, ventilation, and air conditioning (HVAC) make-up filter charcoal filter absorber unit and the control center HVAC recirculation filter charcoal absorber unit, it will inspect the internal surfaces of the piping downstream of the manual isolation valves whenever the charcoal is replaced. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Section 13.4.3.2.2.4, a licensee should conduct deluge valve testing at least every 3 years. It is not clear to the staff that these statements are consistent because during the audit, the staff reviewed charcoal filter media replacement work orders and determined that media is replaced approximately every 7 to 10 years. | |||
* The acceptance criteria program element of the LRA AMP, as amended by letter dated July 30, 2014, does not include an acceptance criteria associated with corrosion of sprinklers during periodic visual sprinkler inspections. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Section 5.2.1.1.2, licensees should replace sprinklers that exhibit corrosion. It is not clear to the staff that these statements are consistent because the Fire Water System Program does not include a criterion to replace corroded sprinklers and the applicant did not provide a basis for why corroded sprinklers can remain in service. | |||

However, the staff found that for the scope of program program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* The Flow Accelerated Corrosion Program includes safety-related components. Electric Power Research Institute (EPRI) guidelines in Nuclear Safety Analysis Center (NSAC)-202L, Recommendations for an Effective Flow Accelerated Corrosion Program, recommend that appropriate quality assurance be applied to all phases of the Flow Accelerated Corrosion Program. The current Flow Accelerated Corrosion Program allows projected wall thicknesses to be determined using a wear value that is calculated by the CHECWORKSTM computer software. The wall thickness projection ensures that a component will continue to meet the minimum wall thickness allowed by design codes until its next scheduled inspection. Fermi 2 currently classifies CHECWORKSTM as a Category B software, which should not be used for safety-related design activities. For safety-related components, it is not clear that only results from software classified as Category A will be used to demonstrate that the design wall thickness will be met at the | |||
55 next refueling outage. Otherwise, the other options included in the Flow Accelerated Corrosion Program, which use wall thickness measurements based on an engineering evaluation of ultrasonic testing data, should be used for safety-related applications. | |||
* Program Notebook PEP19, Flow-Accelerated Corrosion, contains a discussion for the inspection scope selection, which includes a Feedwater Heater Shell Susceptibility Review. However, in its review of LRA Tables 3.4.2-2, Feedwater and Standby Feedwater System, and 3.4.2-3-2, Condensate System, Nonsafety-Related Components Affecting Safety-Related Systems, that contain the feedwater heaters, the staff could not identify any heat exchanger items for the feedwater heater shell that are managed by the Flow Accelerated Corrosion Program. Therefore, it is not clear as to how the effects of aging will be adequately managed for these components. | |||

During the audit, the staff verified that the monitoring and trending and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the scope of program, preventive actions, parameters monitored or inspected and detection of aging effects program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* The GALL Report AMP states that the scope of the program includes high-strength structural bolting. The GALL Report AMP preventive actions program element recommends using bolting material that has an actual measured yield strength of less than 150 kilopounds per square inch (ksi). The GALL Report AMP parameters monitored or inspected program element also recommends that high-strength structural bolting (actual measured yield strength greater than or equal to 150 ksi) in sizes greater than 1 inch nominal diameter, susceptible to stress corrosion cracking be monitored for cracking. In addition, the GALL Report AMP detection of aging effects program element recommends that, for high-strength structural bolting (actual measured yield strength greater than or equal to 150 ksi) in sizes greater than 1 inch nominal diameter, volumetric examination be performed to detect cracking. It is not clear that the Inservice Inspection-IWF Program is consistent with the GALL Report AMP because, based on its review of the LRA and associated AMP basis documents, the staff found no mention of the GALL Report AMP XI.S3 recommendations in the preventive actions, parameters monitored or inspected, and detection of aging effects program elements recommendations described above. In addition, for the scope of program program element it is not clear if there are high-strength structural bolts (actual measured yield strength greater than or equal to 150 ksi) in sizes greater than 1 inch nominal diameter within the scope of the Inservice Inspection-IWF Program. | |||
During the audit, the staff made the following observations: | |||

* The Inservice Inspection-IWF Program basis document states that Fermi 2 does not have ASME Code Section XI, Subsection IWF vibration isolation supports. The staff performed a database search using the keyword | * The Inservice Inspection-IWF Program basis document states that Fermi 2 does not have ASME Code Section XI, Subsection IWF vibration isolation supports. The staff performed a database search using the keyword vibration isolator and found no vibration isolation supports within the scope of the Inservice Inspection-IWF Program. | ||
* LRA Table 3.5.1, item 3.5.1-75, addresses sliding surfaces of column base plates that rest on Lubrite pads exposed to air - indoor uncontrolled. The LRA states that | * LRA Table 3.5.1, item 3.5.1-75, addresses sliding surfaces of column base plates that rest on Lubrite pads exposed to air - indoor uncontrolled. The LRA states that [l]ubrite plates are not subject to aging management because the listed aging mechanisms are event driven and typically can be avoided though proper design. The staff reviewed the applicants claim and noted that the applicant has not screened in any sliding surfaces with Lubrite within the scope of license renewal. During the audit, the staff performed a search of the applicants operating experience database and found no results for the keyword Lubrite. | ||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. The staff also determined that the operating experience provided by the applicant and identified by the staffs independent database search is not sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage the effects of aging. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* ASME Code Section XI, Subsection IWF, states, that to the extent practical, the same supports selected for examination during the first inspection interval shall be examined during each successive inspection interval. Recent industry operating experience has revealed situations in which supports within the IWF sample were degraded, but did not meet the IWF threshold for repair. The supports were reworked to as-new condition and remained in the IWF sample. The staffs concern with respect to aging management is that if ASME Code, Section XI, Subsection IWF supports that are part of the inspection sample are reworked to as-new condition, they are no longer typical of the other supports in the population. Subsequent ASME Code, Section XI, Subsection IWF inspections of the same sample would not represent the age-related degradation of the rest of the population. The LRA and the associated basis documents provided no discussion of how this issue would be addressed. | |||
* The LRA states that [p]lant procedures prohibit the use of lubricants containing molybdenum disulfide. GALL Report AMP XI.S3 preventive action program element states that molybdenum disulfide should not be used as a lubricant due to its potential contribution to SCC, especially for high-strength bolts. During the audit, the staff was able to confirm that plant procedures inhibit the use of molybdenum disulfide lubricants; however, it is not clear whether molybdenum disulfide lubricants have been used at Fermi 2 before plant procedures were revised to prohibit their use. If these lubricants have been used, the staff needs additional information regarding what will be done to age manage structural bolts lubricated with molybdenum disulfide. | |||
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR. The staff found that sufficient information was not available to determine whether the description provided in the UFSAR supplement was an adequate description of the LRA AMP. | |||
61 Audit Results. Based on this audit, the staff verified that the monitoring and trending and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.S3. The staff also identified certain aspects of the scope of program, preventive actions, parameters monitored or inspected, and detection of aging effects program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined. | |||
Based on this audit, the staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR. | |||
LRA AMP B.1.23, Inspection of Overhead Heavy Load and Light Load (Related to Refueling) Handling Systems Summary of Information in the Application. The LRA states that AMP B.1.23, Inspection of Overhead Heavy Load and Light Load (Related to Refueling) Handling Systems, is an existing program with enhancements that is consistent with the program elements in GALL Report AMP XI.M23, Inspection of Overhead Heavy Load and Light Load (Related to Refueling) Handling Systems. To verify this claim of consistency, the staff audited the LRA AMP. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP. | |||
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff conducted walkdowns of the following equipment areas: reactor building crane, turbine building cranes, hoist for residual heat removal pumps Division 1 A and C, hoists for core spray pumps A and C, reactor core isolation cooling (RCIC) pump and turbine hoist Division 1, and channel handling boom jib crane (nonsafety related). The staff also conducted an independent search of the applicants operating experience database using the keywords: crane, steel, rail, wear, corrosion, bolt, and preload. | |||

LRA AMP B.1.24, Internal Surfaces in Miscellaneous Piping and Ducting Components Summary of Information in the Application. The LRA states that AMP B.1.24, Internal Surfaces in Miscellaneous Piping and Ducting Components, is a new program that will be consistent with the program elements in GALL Report AMP XI.M38, Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components, as modified by LR-ISG-2012-02, Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion under Insulation. To verify this claim of consistency, the staff audited the LRA AMP. | |||

64 Although the staff verified the program elements to be consistent with those in GALL Report AMP XI.M38, the staff noted an issue that may require an RAI for clarification. | |||
* The applicants program manages reduction of heat transfer due to fouling for heat exchanger tubes and fins exposed to various air environments, as listed in LRA Table 3.3.2-11. Based on discussions during the audit, some of the associated components are related to room coolers that are within the scope of GL 89-13, Service Water System Problems Affecting Safety-Related Equipment. The staff noted that GL 89-13 expects heat exchangers to be tested or inspected at least every 5 years, whereas the Internal Surfaces in Miscellaneous Piping and Ducting Components Program includes only a 20 percent sample that is inspected every 10 years. Therefore, it is not clear whether implementation of the Internal Surfaces in Miscellaneous Piping and Ducting Components Program would relax existing current licensing basis inspections for these room coolers. | |||
The LRA states that the program is new and therefore provides no operating experience associated with the program. The operating experience basis document, FERMI-RPT-12-LRD09, states that a search of operating experience associated with ducts and housings did not identify any aging effects beyond those identified in the GALL Report. During the audit of the operating experience program element, the staffs independent database search did not identify any plant-specific operating experience that would indicate that the program is not capable of managing the effects of aging for components within the programs scope. | |||

During the audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the acceptance criteria program element, sufficient information was not available to determine whether it was consistent with the corresponding program elements of the GALL Report AMP.

This section provides qualitative criteria, described in terms of structural function only, for evaluation of inspection results. The GALL Report AMP states that the extent of observed shrinkage and/or separation and cracking of masonry may not invalidate the evaluation basis or impact the walls intended function. It recommends that further evaluation is conducted if the extent of cracking and loss of material is sufficient to impact the intended function of the wall or invalidate its evaluation basis. It is not clear to the staff that this element of the LRA AMP is consistent with the recommendations in GALL Report AMP XI.S5 because the LRA acceptance criteria do not appear to address the invalidate evaluation basis aspect of the GALL Report acceptance criteria. | ||

For the parameters monitored or inspected and detection of aging effects program elements sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subject(s) discussed below. | |||
* The applicant stated that one method of testing cable connections relied upon for maintenance is the use of thermography (infrared inspection). The staff reviewed the applicants thermography procedure 47.000.88. It is not clear to the staff that the thermography inspections are directed to take place under normal full load conditions of the affected electrical connections. | |||
* It is not clear to the staff as to whether the representative sample designated by the applicant adequately addresses the various connection types noted by the staff (per Spec. No. 3071-128-EQ). | |||
* Maintenance Procedures 35.301.001 and 35.301.001 provide values for checking the connection tightness by providing electrical connection torque values. It is not clear to the staff that these procedures are consistent with EPRI Guidance (EPRI TR-104213, Bolted Joint Maintenance & Applications Guide) concerning re-torqueing of electrical connections. | |||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff). A total of 57 work orders were identified. The review of the identified items did not reveal any significant or unusual operating experience issues. | |||
During the staff walkdown, the staff identified concerns with cable connection maintenance. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subject(s) discussed below. | |||
* During the electrical connection walkdown, the staff noted two 3000 amp/1200 amp bus tap boxes located in the Division 2 ESS 4160 V and 480 V switchgear room. It is not clear to the staff whether the connections inside these tap boxes are inspected under the current preventive maintenance procedures. These connections are within the scope of license renewal. The staff is concerned that if the in-scope tap box connections are not inspected or tested under current plant maintenance programs, then a one-time test under LRA AMP B.1.28 performed on a sampling basis may not be adequate to ensure | |||
72 that either aging of metallic cable connections is not occurring and/or that the existing preventive maintenance program is effective such that a periodic inspection program is not required. | |||
* It is not clear to the staff what routine maintenance is currently performed on the in-scope safety related 4160 V bus (including low side connections of transformer SS #65) electrical connections. The staff concern is that a one-time test under LRA AMP B.1.28 performed on a sampling basis may not be adequate to ensure that either aging of metallic cable connections is not occurring and/or that the existing preventive maintenance program is effective such that a periodic inspection program is not required. | * It is not clear to the staff what routine maintenance is currently performed on the in-scope safety related 4160 V bus (including low side connections of transformer SS #65) electrical connections.

The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR for a one-time inspection. | |||
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.E6. The staff also identified certain aspects of the parameters monitored or inspected and detection of aging effects program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined. | |||

* The program enhancement states that the applicant will revise its procedures to ensure that new fluence projections through the period of extended operation and the latest vessel beltline adjusted reference temperature tables are provided to the Boiling Water Reactor Vessel Internals Project prior to the period of extended operation (i.e., prior to September 20, 2024). The staff noted that the applicants program is an existing program and upon receipt of renewed license the program should continue to provide adequate fracture toughness and dosimetry data throughout the license renewal term. | |||
However, the LRA states that the applicants enhancement will be implemented prior to the period of extended operation, but not within a specific time period upon receipt of renewed license. The staff finds that the enhancement regarding data sharing is important to maintain the effectiveness of the Integrated Surveillance Program (ISP) and, therefore, it is necessary to implement the program enhancement within a specific time period upon receipt of renewed license unless adequate justification is provided. | |||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff). | |||
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff found that sufficient information was not available to determine whether the description provided in the UFSAR supplement was an adequate description of the LRA AMP.

During the audit, the staff verified that the scope of program, preventive actions, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
91 | 91 | ||
* The | * The parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements of GALL Report AMPs XI.S6 and XI.S7, explicitly address the aging management of high-strength (measured yield strength greater than or equal to 150 ksi) structural bolts greater than 1 inch in diameter. The GALL Report recommends that visual inspections of high-strength structural bolts be supplemented with volumetric or surface examinations to detect cracking. It is not clear if there are high-strength structural bolts used in Fermi 2 structures (other than ASTM A325, F1852, and A490 used in civil structures) and, if used, whether the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements of LRA Sections B.1.42 and B.1.39, are consistent with the recommendations in GALL Report AMPs XI.S6 and XI.S7 regarding the provision to monitor for stress corrosion cracking in high-strength structural bolts greater than 1 inch in diameter through supplemental volumetric or surface examinations to detect cracking. | ||
* The | * The detection of aging effects program element of the LRA AMP states that inspection of water-control structures will be performed on an interval not to exceed 5 years. The GALL Report AMP recommends periodic inspections to be performed at least once every 5 years. The GALL Report also recommends that the program should include provisions for increased inspection frequency if the extent of the degradation is such that the structure or component may not meet its design basis if allowed to continue uncorrected until the next normally scheduled inspection. It is not clear to the staff that the detection of aging effects program element is consistent with the recommendations in GALL Report AMP XI.S7 because no discussion regarding the provision for increased inspection frequency was provided by the applicants AMP. | ||
* As described in the LRA AMP | * As described in the LRA AMP program description in relation to the detection of aging effects program element, the program performs periodic visual examinations to monitor the condition of water-control structures and structural components, including steel piles required for the stability of the shore barrier. The GALL Report AMP recommends visual inspections to detect degradation of water-control structures. However, during its onsite audit, the staff noted that the applicant does not plan to perform visual inspections of the submerged steel piles at the shore barrier. It is not clear how the effects of aging of the steel piles will be adequately managed during the period of extended operation. | ||

During the audit, the staff verified that the scope of program and monitoring and trending program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the preventive actions, parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below. | |||
* The preventive actions, parameters monitored or inspected, and detection of aging effects program elements of GALL Report AMP XI.S6 explicitly address the aging management of ASTM A325, ASTM F1852, and ASTM A490 structural bolting. The staff noted that the corresponding elements, with enhancements, of the LRA AMP basis document address ASTM A325 and A490 bolting, but made no mention of ASTM F1852 bolting. It is not clear to the staff that the above mentioned program elements of the LRA AMP are consistent with the recommendations in the GALL Report AMP because there was no mention of ASTM F1852 bolting. | |||
* The preventive actions, parameters monitored or inspected and detection of aging effects program elements of the GALL Report AMP recommends monitoring | |||
97 high-strength bolting greater than 1 inch in diameter for stress corrosion cracking and supplementing visual inspection with volumetric or surface examinations to detect SCC. | |||
The corresponding program elements of the LRA AMP basis document for the Structures Monitoring Program state that plant procedures prevent the use of molybdenum disulfide as a lubricant for bolting, and therefore [high-strength] structural bolting is not susceptible to SCC. This explanation seems to be used as the basis for not supplementing visual examinations of high-strength bolting greater than 1 inch in diameter with volumetric or surface examination as recommended in the GALL Report AMP. The staff notes that the use of molybdenum disulfide is not the only contributor to SCC of high-strength bolts. Also, it is not clear from the LRA program basis document whether high-strength structural bolts are used in Fermi 2 structures and whether molybdenum disulfide lubricants have been used at Fermi 2 before plant procedures were revised to prohibit its use. The staff needs additional information to verify consistency with the GALL Report AMP because is not clear if there are high-strength structural bolts used in Fermi 2 structures and, if used, whether the program elements are consistent with the recommendations in GALL Report AMP XI.S6 and XI.S7 regarding the provision to monitor for SCC through supplemental volumetric or surface examinations to detect cracking. | |||
* The detection of aging effects program element in the LRA AMP basis document states that underground (inaccessible areas) of concrete structures are subject to an aggressive groundwater/soil environment. The GALL Report AMP recommends a plant-specific program to manage concrete aging effects for inaccessible areas subject to an aggressive groundwater/soil environment. The detection of aging effects program element of the LRA AMP includes an enhancement to revise plant procedures to perform opportunistic inspections of inaccessible areas if it becomes accessible for some reason, and additionally, perform inspections of inaccessible areas in environments where observed conditions in accessible areas exposed to the same environment indicate significant degradation. The staff needs additional information to verify consistency with the GALL Report for the detection of aging effects in inaccessible, below-grade concrete structural elements exposed to an aggressive groundwater/soil environment because the proposed enhancement to the Structures Monitoring Program does not appear to be consistent with the GALL Report recommendations for either an aggressive or non-aggressive water/soil environment. | |||
Further, the enhancement for inspections of inaccessible areas based on observations of accessible areas with the same environment appears to limit the scope of inaccessible areas that will be inspected because certain environment conditions may not exist for both accessible and inaccessible areas (i.e., a soil type environment may exist for an inaccessible area and not for an accessible area). | |||
* The LRA AMP includes enhancements to the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements to revise procedures to meet the guidelines provided in American Concrete Institute (ACI) 349.3R to demonstrate consistency with the GALL Report with regard to selection of parameters monitored, personnel qualifications requirements, and prescribing quantitative acceptance criteria. The program basis document for the LRA AMP references the 1996 edition of ACI 349.3R. However, the GALL Report AMP XI.S6 is based on, and references, the 2002 edition of ACI 349.3R. It is not clear to the staff that the use of the 1996 edition of ACI 349.3R is consistent with the GALL Report because there are substantive differences between the 2002 edition and 1996 edition of ACI 349.3R that introduce potential inconsistencies. | |||
The staff | |||
98 During the audit, the staff made the following observations: | |||
* The staff performed a walkdown of the turbine building basement and observed leaching of concrete. The staff reviewed CARD Nos. 10-22385, 12-27792, and 09-26756, which document the presence of leaching in the RHR complex, auxiliary building basement, and reactor building sub-basement. The applicant determined that leaching is due to groundwater in-leakage and that the identified condition does not affect the structural integrity of the structures. However, there is no discussion in LRA AMP operating experience about leaching issues identified at the plant and no discussion about the evaluation performed that documents the impact of observed leaching on the intended function of the concrete and rebar. Additionally, the staff is not clear how LRA Table 3.5.1, item 47, which states that leaching has not been observed on accessible portions of concrete at Fermi 2, is consistent with the GALL Report recommendation when the operating experience provided by the applicant during the audit documents the presence of leaching in structures. | |||
* During the staffs independent database search of operating experience, the staff reviewed CARD No. 13-25947 and noted that the applicant practice to reject concrete with air entrainment outside the 4.5 percent to 7.5 percent range due to inadequate air entrainment content is consistent with the GALL Report recommendation of adequate air content for concrete exposed to cycles of freezing and thawing. The SRP-LR states that the Structures Monitoring Program may not be sufficient to manage loss of material and cracking due to freeze-thaw for plants located in moderate to severe weathering conditions. However, a plant-specific program is not required if documented evidence confirms that the existing concrete has air content between 3 and 8 percent and inspections have not identified degradation related to freeze-thaw. | |||
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff). | |||
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR. | |||
Audit Results. Based on this audit, the staff verified that the scope of program, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.S6. The staff also identified certain aspects of the preventive actions, parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined. | |||

1 Introduction The U.S. Nuclear Regulatory Commission (NRC or the staff) conducted a 10-day audit at the Fermi 2 Nuclear Power Plant (Fermi 2), in Newport, MI, from September 15 to October 3, 2014.
The purpose of the audit was to examine DTE Electric Companys (DTE or the applicant) aging management programs (AMPs) and related documentation to verify the applicants claims of consistency with the corresponding AMPs in NUREG-1801, Revision 2, Generic Aging Lessons Learned (GALL) Report, dated December 2010. As described in the GALL Report, the staff based its evaluation of the adequacy of each AMP on its review of the following 10 program elements in each AMP: (1) scope of the program; (2) preventive actions; (3) parameters monitored or inspected; (4) detection of aging effects; (5) monitoring and trending; (6) acceptance criteria; (7) corrective actions; (8) confirmation process; (9) administrative controls; and (10) operating experience.
Exceptions to the GALL Report AMP elements will be evaluated separately as part of the staffs review of the Fermi 2 license renewal application (LRA) and documented in the staffs safety evaluation report (SER).
NUREG-1800, Standard Review Plan for Review of License Renewal Applications for Nuclear Power Plants (SRP-LR), Revision 2, dated December 2010, provides staff guidance for reviewing an LRA. The SRP-LR allows an applicant to reference in its LRA the AMPs described in the GALL Report. By referencing the GALL Report AMPs, the applicant concludes that its AMPs correspond to those AMPs reviewed and approved in the GALL Report and that no further staff review is required. If an applicant credits an AMP for being consistent with a GALL Report program, it is incumbent on the applicant to ensure that the plant program contains all of the elements of the referenced GALL Report program. The applicants determination should be documented in an auditable form and maintained onsite.
During the audit, the staff audited AMP elements 1 - 6 and 10 (scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, acceptance criteria, and operating experience). These elements of the applicants AMPs were claimed to be consistent with the GALL Report and were audited against the related elements of the associated AMP described in the GALL Report, unless otherwise indicated in this audit report. Elements 7 - 9 (corrective actions, confirmation process, and administrative controls) were audited during the scoping and screening methodology audit conducted on August 4 - 7, 2014, and are evaluated separately. The staff audited all AMPs that the applicant stated were consistent with the GALL Report AMPs.
During the audit, if the applicant took credit for a program in the GALL Report, the staff verified that the plant program contained all the elements of the referenced GALL Report program.
In addition, the staff verified the conditions at the plant were bounded by the conditions for which the GALL Report program was evaluated.
In addition to auditing AMP elements 1 through 6 and 10, the staff also reviewed documentation associated with the following aging management review (AMR) items: (1) LRA Table 3.3.2-6, Compressed Air Systems, (2) LRA Table 3.3.2-12, Control Center Heating, Ventilation and Air Conditioning System, and (3) LRA Table 3.4.2-3-7, Circulating Water System, Nonsafety-Related Components Affecting Safety-Related Systems. The activities and observations associated with these AMR items are documented at the end of this report.
2 In performing the audit, the staff examined the applicants LRA, program-bases documents, and related references; interviewed various applicant representatives; and conducted walkdowns of several plant areas. In total, 44 AMPs were reviewed and 41 breakout (discussion) sessions with applicant representatives were conducted. This report documents the staffs activities during the audit.
LRA AMP B.1.1, Aboveground Metallic Tanks Summary of Information in the Application. The LRA states that AMP B.1.1, Aboveground Metallic Tanks, is a new program that will be consistent with the program elements in GALL Report AMP XI.M29, Aboveground Metallic Tanks, as modified by License Renewal Interim Staff Guidance (LR-ISG)-2012-02, Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion under Insulation. To verify this claim of consistency, the staff audited the LRA AMP. At the time of the audit, the applicant had not yet fully developed the documents necessary to implement this new program, and the staffs audit addressed only the program elements described in the applicants basis document and applicable plant-specific operating experience. Issues identified but not resolved in this report will be addressed in the SER.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff conducted walkdowns of the combustion turbine generator (CTG) fuel oil tank and condensate storage tank (CST). The staff also conducted an independent search of the applicants operating experience database using the keywords: tank, inspect and insulation.
The table below lists the documents that were reviewed by the staff and were found relevant to the audit. These documents were provided by the applicant or were identified in the staffs search of the applicants operating experience database.

Drawing 5M721-5922 Revision A Cone Roof and Shell Layout During the audit of program elements one through six, the staff verified that the scope of program, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. For the preventive actions program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing a request for additional information (RAI) for the subject discussed below.
- The preventive actions program element of the LRA AMP states that [i]n accordance with installation and design specifications, the tanks do not employ caulking or sealant at the concrete/tank interface. The GALL Report AMP recommends that sealant or caulking be applied to outdoor tanks at the external interface between the tank and concrete foundation. The function of the sealant or caulk is to minimize the amount of water and moisture penetrating the interface between the tank and concrete foundation.
The GALL Report AMP further states that sealant or caulking are not necessary if the configuration of both the tank bottom and foundation is sloped in such a way that water cannot accumulate.
It is not clear to the staff that these statements are consistent for the CST. The design of the CST foundation is a concrete ring with the tank bottom in contact with graded sand. The design also incorporates drains to facilitate the removal of water from the interior of the concrete ring foundation. However, the top surface of the concrete ring is not sloped to prevent water and moisture intrusion at the outside interface of the ring foundation. The accumulation of water or moisture at the outside interface of the ring foundation could result in the loss of material or cracking of the aluminum.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing an RAI for the subject discussed below.
- During the review of the past 10-years of applicable operating experience it was noted that there have been multiple instances of degradation of the insulation and jacketing on the roof of the CST, including separations in the sheet metal seams, loss of flashing, and loss of insulation due to weather. In 2013 the CST roof insulation was completely
4 removed and pre-fabricated insulation was installed. The as-found condition of the aluminum roof was not documented in the work order. The aluminum roof has been exposed to weather on multiple occasions and it is unclear if there is any age-related degradation under the pre-fabricated insulation.
The staff also audited the description of the LRA AMP provided in the updated final safety analysis report (UFSAR) supplement. The staff found that sufficient information was not available to determine whether the description provided in the UFSAR supplement was an adequate description of the LRA AMP. In order to obtain the information necessary to verify the sufficiency of the UFSAR supplement program description, the staff will consider issuing an RAI for the subject discussed below.
- The UFSAR supplement contains a commitment (Commitment No. 3) to implement the Aboveground Metallic Tanks Program. The implementation schedule for this commitment is [p]rior to September 20, 2024, or the end of the last refueling outage prior to March 20, 2025. LR-ISG-2012-02, Table 3.0-1, recommends that the program be implemented 10 years prior to the period of extended operation. The recommendation to implement the program 10 years prior to the period of extended operation is to support the inspection guidance provided in LR-ISG-2012-02, Table 4a, Tank Inspection Recommendations. The guidance provided in Table 4a includes inspections of all tank interior and exterior surfaces, including tank tops and bottoms, in timeframes ranging from within 5 to 10 years prior to the period of extended operation.
Audit Results. Based on this audit, the staff verified that the scope of program, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M29. The staff also identified certain aspects of the preventive actions program element of the LRA AMP for which additional information or evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. The staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP.
In addition, the staff identified a need for additional information regarding the adequacy of the program description in the UFSAR supplement.
LRA AMP B.1.2, Bolting Integrity Summary of Information in the Application. The LRA states that AMP B.1.2, Bolting Integrity, is an existing program with enhancements and an exception that is consistent with the program elements in GALL Report AMP XI.M18, Bolting Integrity. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP. The exception to the GALL Report AMP not necessary for consistency with the GALL Report is evaluated in the SER.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff conducted walkdowns of the turbine building, reactor building, and the residual heat removal (RHR) complex. The staff also
5 conducted an independent search of the applicants operating experience database using the keywords: bolt, torque, preload, crack, leak, corrosion, and seal cap.

WO 34488149 Check torque and lockwire EDG [emergency diesel 10/11/2012 generator] 11 Vertical Drive Bolts The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements. Aspects of the detection of aging effects program element of the LRA AMP associated with the exception were not evaluated during this audit. Aspects of this program element that are not associated with the exception were evaluated and are described below.
During the audit, the staff verified that the preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. The staff noted that aspects of the detection of aging effects program element not associated with the exception are not consistent with the corresponding program element in the GALL Report AMP.
The staffs evaluation of aspects of the detection of aging effects program element associated with the exception will be addressed in the SER. In addition, the staff found that for the scope of program program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
- LRA Section B.1.2 states that the Bolting Integrity Program manages loss of preload, cracking, and loss of material for accessible closure bolting for safety-related and nonsafety-related pressure components. GALL Report AMP XI.M18 scope of program program element states that the program manages aging of closure bolting for pressure retaining components within the scope of license renewal, including both safety-related and non-safety-related bolting. The GALL Report AMP also recommends periodic inspections of closure bolting be performed at least once per refueling cycle for signs of leakage to ensure the detection of age-related degradation due to loss of material and loss of preload. It is not clear to the staff whether all pressure-retaining closure bolting (both accessible and inaccessible) within the scope of license renewal is managed for age-related degradation. In addition, if inaccessible bolting is managed differently, the
7 staff is not clear as to the applicants criteria for considering bolting inaccessible. The staff needs this information to determine whether the effects of aging will be managed consistent with the recommendations in the GALL Report AMP.
- LRA Section B.1.2 states an enhancement to the Bolting Integrity Program to revise the procedures to inspect the residual heat removal service water (RHRSW), emergency equipment service water (EESW), and emergency diesel generator service water system pump and valve bolting submerged in the RHRSW reservoir at least once per refueling outage. GALL Report AMP XI.M18 detection of aging effects program element recommends periodic inspections (at least once per refueling cycle) of closure bolting for signs of leakage to ensure the detection of age-related degradation due to loss of material and loss of preload. The staff reviewed the program basis documents and was not clear how the submerged closure bolting will be inspected such that loss of material and loss of preload can be detected prior to loss of intended function consistent with the GALL Report AMP detection of aging effects program element.
During the audit the staff performed a database search of Fermi 2 operating experience and found no results for the keyword seal cap associated to their installation for closure bolting at Fermi 2.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. The staff also determined that the operating experience provided by the applicant and identified by the staffs independent database search is not sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage the effects of aging. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing an RAI for the subject discussed below.
- The LRA states that [p]lant procedures prohibit the use of lubricants containing molybdenum disulfide. The GALL Report AMP states that molybdenum disulfide should not be used as a lubricant due to its potential contribution to stress corrosion cracking (SCC), especially for high-strength bolts. During the audit the staff was able to confirm that plant procedures prohibit the use of molybdenum disulfide lubricants; however, it is not clear whether molybdenum disulfide lubricants have been used at Fermi 2 before plant procedures were revised to prohibit their use. If these lubricants have been used in the past, the staff needs additional information regarding how the program will manage aging of closure bolts lubricated with molybdenum disulfide.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M18. The staffs evaluation of aspects of the detection of aging effects program element associated with exceptions will be addressed in the SER. The staff also identified certain aspects of the scope of program and detection of aging effects program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
8 Based on this audit, the staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.3, Boraflex Monitoring Summary of Information in the Application. The LRA states that AMP B.1.3, Boraflex Monitoring, is an existing program with enhancements that will be consistent with the program elements in GALL Report AMP XI.M22, Boraflex Monitoring. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicants operating experience database using the keywords: Boraflex, neutron-absorber, and coupon.

- 13. NET-300010-01 BADGER Test Campaign at Enrico Fermi Power Plant 2 The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements.
During the audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff). In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subject discussed below.
- The applicant stated that three Boraflex panels were taken out of service due to the fact that their boron-10 areal density measurement test results did not meet the acceptance criteria. The measurement test results are provided in the 2013 Fermi 2 BADGER report, which summarizes the Boraflex test campaign conducted in 2013. The report provides information on the condition of the Boraflex material in the spent fuel pool. The staff reviewed the 2013 BADGER test report briefly during the audit; however, more information is needed to complete the review. The staff requests that the applicant provide this report to the NRC so a more detailed review can be performed.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified that this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M22.
Based on this audit, the staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.4, Buried and Underground Piping Summary of Information in the Application. The LRA states that AMP B.1.4, Buried and Underground Piping, is a new program that will be consistent with the program elements in GALL Report AMP XI.M41, Buried and Underground Piping and Tanks, as modified by LR-ISG-2011-03, Changes to the Generic Aging Lessons Learned (GALL) Report Revision 2 Aging Management Program XI.M41, Buried and Underground Piping and Tanks. To verify
10 this claim of consistency, the staff audited the LRA AMP. At the time of the audit, the applicant had not yet fully developed the documents necessary to implement this new program, and the staffs audit addressed only the scope of the program, buried and underground inspection results, cathodic protection acceptance criteria, risk ranking of inspection locations, plant-specific operating experience, and the UFSAR supplement. Issues identified but not resolved in this report will be addressed in the SER.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff conducted a walkdown of the condensate storage tank dog house pit entranceway in order to view the associated underground piping. The staff also conducted an independent search of the applicants operating experience database using the keywords: buried, coat, degrad, dug, excavat, holiday, leak, through-wall, and vault.

12 GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. For the detection of aging effects and acceptance criteria program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of GALL Report AMP XI.M41, as modified by LR-ISG-2011-03, the staff will consider issuing RAIs for the subjects discussed below.
- The detection of aging effects program element of the LRA AMP states that buried piping inspections will be conducted in a manner consistent with those in the detection of aging effects element of GALL Report AMP XI.M41, as modified by LR-ISG-2011-03.
During the staffs review of buried pipe inspection reports, it was noted that the coatings for two excavated pipe inspections were classified as being in fair condition. However, the reports for the two inspections state that coating holidays ranging in size from 2 in2 to 10 in2 for one pipe and 30 in2 to 95 in2 for the other pipe were detected. The classification of the coating condition may not be consistent with LR-ISG-2011-03 Table 4a, Inspections of Buried Pipe, footnote 2, which states that inspection category E, opposed to F (category E has a lower number of inspections relative to F),
may be used if there is no significant coating degradation. The staff lacks sufficient information to conclude that, given the size of the holidays reported; the coating condition is appropriately classified as fair rather than significantly degraded. As a result of classifying the coatings as being in fair condition, the number of inspections conducted may not be consistent with the detection of aging effects program element of GALL Report AMP XI.M41, as modified by LR-ISG-2011-03.
- The acceptance criteria program element of the LRA AMP states that the program activities associated with the acceptance criteria are consistent with GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. The GALL Report AMP recommends that if a 100 millivolt (mV) polarization criterion is used to assess the performance of the cathodic protection system, the LRA should include the basis for why adequate protection is provided for steel components exposed to a mixed potential environment.
The applicants acceptance criteria for the cathodic protection system includes negative 0.85 volts and 100 mV of cathodic polarization. The applicants acceptance criteria also includes an allowance for polarization potentials less negative than 0.85 volts if the buried components are in high resistivity soils that are well drained and well aerated.
The applicant did not provide the basis for the acceptance criterion of the cathodic protection system.
During the audit, the staff made the following observations:
- The staff reviewed drawing 4P-644 and confirmed that buried piping penetrates plant building walls through a steel sleeve and is therefore not in contact with concrete.
- The staff reviewed program manual PEP31 and confirmed that the acceptance criteria for cathodic protection includes: (a) at least negative 0.85 volts, (b) a minimum of 100 mV of cathodic polarization, and (c) a polarization potential of less negative than 0.85 volts if the component is buried in high resistivity soil (greater than 10,000 ohm-cm) that is well drained and well aerated.
- The staff reviewed the buried piping drawings listed above, documents 23 through 32, and confirmed that there are no bolted flanged connections in the buried steam and power conversion systems.
13 During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff).
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in LR-ISG-2011-03 Table 3.0-1.
Audit Results. Based on this audit, the staff verified that the scope of program, parameters monitored or inspected, preventive actions, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M41, as modified by LR-ISG-2011-03. The staff also identified certain aspects of the detection of aging effects and acceptance criteria program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in LR-ISG-2011-03 Table 3.0-1.
LRA AMP B.1.5, BWR CRD Return Line Nozzle Summary of Information in the Application. The LRA states that AMP B.1.5, BWR CRD Return Line Nozzle, is an existing program that is consistent with the program elements in GALL Report AMP XI.M6, BWR Control Rod Drive Return Line Nozzle. To verify this claim of consistency, the staff audited the LRA AMP.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicants operating experience database using the keywords: return line nozzle, fatigue, and crack.

NUREG-0619 November 1980 Line Nozzle Cracking During the audit of program elements one through six, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP.
During the audit, the staff made the following observation:
- Per UFSAR Section 4.5.2.2.2.3, the applicant has eliminated the control rod drive return line as a preventive measure to avoid cracking. With this design change and the other system modifications described in UFSAR Section 4.5.2.2.2.3, there are no ongoing maintenance or testing activities from NUREG-0619 that would apply to Fermi 2.
Therefore, under the applicants Boiling-Water Reactor (BWR) Control Rod Drive Return Line Nozzle Program, the only activities for detecting the effects of cracking are the periodic examinations that are implemented in accordance with American Society of Mechanical Engineers (ASME) Code,Section XI, Table IWB-2500-1.
15 During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff).
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M6.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.6, BWR Feedwater Nozzle Summary of Information in the Application. The LRA states that AMP B.1.6, BWR Feedwater Nozzle, is an existing program that is consistent with the program elements in GALL Report AMP XI.M5, BWR Feedwater Nozzle.

During the audit of program elements one through six, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. For the detection of aging effects program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
- The LRA states that the BWR Stress Corrosion Cracking Program is consistent with GALL Report AMP XI.M7, with no exceptions. The detection of aging effects program element of the GALL Report AMP states that the extent and schedule of the inspection are described in NRC Generic Letter (GL) 88-01 and may be modified in accordance with Boiling-Water Reactor Vessel and Internals Project (BWRVIP)-75-A. The staff noted that the applicants Category A welds are subsumed in the applicants risk-informed inservice inspection. The staff also noted that the percentage of Category A welds to be inspected by the applicant is not stated in the LRA. It is unclear to the staff if the extent and schedule of the inspection are consistent with GL 88-01 and BWRVIP-75-A.
- The aging management review tables for the condensate and feedwater systems in the LRA do not include AMR items to manage IGSCC for Category D welds, which were identified in the 1992 communications between the Detroit Edison Company and the NRC (letters dated July 29, 1992, and December 18, 1992, referenced in the document table above). The staff cannot determine the adequacy of the applicants program and AMR results without additional information to justify the omission of relevant AMR items.
- The staff also noted that the 1992 communications (letters dated July 29, 1992, and December 18, 1992, referenced in the document table above) indicate that the applicants Category D welds are located outboard of the containment isolation valves and at least 10 percent of these welds should be inspected during each refueling outage. The staff further noted that the extent and frequency of these inspections are different from the inspection guidelines provided in GL 88-01 and BWRVIP-75-A.
BWRVIP-75-A states that in the case of the implementation of hydrogen water chemistry 100 percent of Category D welds should be inspected every 10 years and at least 50 percent of these welds should be inspected in the first 6 years. However, the LRA does not identify this difference as a program exception. The staff finds that additional information is necessary to clarify why this difference is not identified as a program exception and to confirm whether this difference is acceptable for adequate aging management.
22 During the audit of the operating experience program element, the staff found a need to confirm whether the plant-specific operating experience regarding condenser inleakage affects the sufficiency of the LRA program. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subject discussed below.
- The staff noted that CARD 11-21607 states that during the startup on February 10, 2011, the applicants plant was shut down due to main condenser tube inleakage and associated water chemistry excursions. CARD 11-21607 also indicates that inspections of all condenser water boxes identified the ejection of tube plugs from receptive condenser tubes. The ingress of chloride, sulfate, and other contaminants into the reactor coolant system, due to main condenser inleakage, can promote IGSCC in BWR piping and piping welds. However, LRA Section B.1.8 and the onsite program evaluation report for the applicants program do not clearly address the potential impact of condenser cooling water inleakage on the effectiveness of the applicants program.
The staff finds that additional information is necessary to confirm that the applicants assessment of operating experience regarding condenser inleakage ensures the effectiveness of the applicants program.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M7. The staff also identified certain aspects of the detection of aging effects program element of the LRA AMP for which additional information or evaluation is required before consistency can be determined.
Based on this audit, the staff also finds that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.9, BWR Vessel ID Attachment Welds Summary of Information in the Application. The LRA states that AMP B.1.9, BWR Vessel ID Attachment Welds, is an existing program that is consistent with the program elements in GALL Report AMP XI.M4, BWR Vessel ID Attachment Welds. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicants operating experience database using the keywords: cracking, wear, hold down, core spray, attachment welds, steam dryer, and jet pump.
23 The table below lists the documents that were reviewed by the staff and were found relevant to the audit. These documents were provided by the applicant or were identified in the staffs search of the applicants operating experience database.

During the audit of the operating experience program element, the staff noted inconsistencies in the operating experience provided in the LRA AMP. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing an RAI for the subject discussed below.
- The operating experience section of the LRA discusses plant-specific inspection results from 2001, 2005, and 2012. It specifically states that, In 2005, shroud support weld examinations as well as other inspections of reactor vessel internal welds and components were performed as scheduled by the Reactor Vessel Internals Management (RVIM) program. However, the staff discovered during the onsite audit that there was no such inspection in 2005.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
24 Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M4.
Based on this audit, the staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.10, BWR Vessel Internals Summary of Information in the Application. The LRA states that AMP B.1.10, BWR Vessel Internals, is an existing program with enhancements that will be consistent with the program elements in GALL Report AMP XI.M9, BWR Vessel Internals. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant.

CARD 06-22334 04/14/2006 Visual Inspections The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements. During the audit, the staff verified that the preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the scope of program program element, insufficient information was available to determine if they were consistent with the corresponding program elements of the GALL Report AMP. To obtain the information necessary to verify if these program elements are consistent with the corresponding program elements of the GALL Report, the staff will consider issuing an RAI for the subjects discussed below.
- The scope of program program element of the GALL Report AMP includes BWRVIP-58-A as guidelines for the repair design criteria for the control rod drive housing and BWRVIP-57-A as the guidelines for the repair design criteria for the lower plenum components. The applicant references these documents as the repair design criteria guidelines for these components as well as BWRVIP-55-A; however, the plant procedures only reference BWRVIP-55-A. The staff is unclear if the applicant is using any BWRVIP guidelines beyond those in the GALL Report AMP.
- The scope of program program element of the GALL Report AMP includes BWRVIP guidelines for which the BWR vessel internal components are subject and which may contain applicant action items. The applicant responded to these BWRVIP applicant action items in LRA Appendix C. The staff is unclear if LRA Appendix C includes the accurate list of BWRVIP guidelines actually used at Fermi 2 or if the responses to the applicant action items considered the recently approved measurement uncertainty recapture power uprate.
During the audit of the operating experience program element, the staff determined that the operating experience provided by the applicant and identified by the staffs independent database search is bounded by industry operating experience (i.e., no previously unknown aging effects were identified by the applicant or the staff). The staff also determined that the operating experience provided by the applicant and identified by the staffs independent database search is sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage the effects of aging.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description to be consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M9. The staff also identified certain aspects of the scope of
26 program program element of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.11, Compressed Air Monitoring Summary of Information in the Application. The LRA states that AMP B.1.11, Compressed Air Monitoring, is an existing program with enhancements and an exception that is consistent with the program elements in GALL Report AMP XI.M24, Compressed Air Monitoring. To verify this claim of consistency, the staff audited the LRA AMP. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP. The exception to the GALL Report AMP will be evaluated in the SER.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicants operating experience database using the keywords: dew point, instrument air, air quality, and compressed air.

The staff conducted its audit of LRA program elements one through seven based on the contents of the existing program as modified by the proposed enhancements. The staff notes that the scope of the audit covered the additional program element 7 corrective actions because the applicant included an enhancement for this element to establish consistency with the recommended actions in the corresponding element of the GALL Report AMP XI.S1 that is specific to the potential case if moisture is detected or suspected in the inaccessible area on the exterior of Mark I containment drywell shell.
During the audit, the staff verified that the scope of program, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and corrective actions program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
- The preventive actions program element of GALL Report AMP XI.S1 recommends preventive actions in accordance with Research Council for Structural Connections publication for structural bolting consisting of American Society for Testing and Materials (ASTM) A325, ASTM F1852, and ASTM A490 bolts. The staff noted that the corresponding element, with enhancements, of the LRA AMP basis document (FERMI-RPT-12-LRD05, Revision 1) addresses ASTM A325 and A490 bolting, but made no mention of ASTM F1852 bolting. It is not clear to the staff that the above mentioned program element of the LRA AMP is consistent with the recommendations in the GALL Report AMP because there was no mention of ASTM F1852 bolting. Note that this is a common issue across B.1.12 Containment Inservice Inspection - IWE, B.1.22 Inservice Inspection - IWF, and B.1.42 Structures Monitoring AMPs.
- The detection of aging effects program element of GALL Report AMP XI.S1 recommends that the program be augmented to require surface examination, in addition to visual examination, to detect cracking in stainless steel penetration sleeves, bellows, dissimilar metal welds, and steel components that are subject to cyclic loading but have no current licensing basis fatigue analysis. The GALL Report AMP also states that where feasible, appropriate Appendix J tests may be performed in lieu of surface examination. The LRA AMP program basis document states that the above mentioned components are monitored for cracking. It also states that, additionally, XI.S4 Containment Leak Rate Program tests may be performed in lieu of surface examination.
31 It is not clear to the staff that these statements are consistent because the LRA AMP basis document does not state that to detect cracking supplemental surface examination will be performed on the subject components, in addition to visual examination. Further, it does not identify the specific components for which the option to perform Appendix J tests, in lieu of surface examination, will be used and the type of Appendix J test that would be performed in order for staff to evaluate the appropriateness of the test to detect cracking in these components prior to loss of intended function.
- The preventive action program element of GALL Report AMP XI.S1 recommends that the program be augmented to include preventive actions that ensure that moisture levels associated with an accelerated corrosion rate do not exist in the exterior portion of the BWR Mark I steel containment drywell shell. The actions consist of ensuring that the sand pocket area drains and/or the refueling seal drains are clear. The parameters monitored or inspected program element of the GALL Report AMP recommends that applicants with BWR Mark I steel containments should monitor sand pocket area drains and/or the refueling seal drains for water leakage. The licensees should ensure the drain lines are clear to prevent moisture levels associated with accelerated corrosion rates in the exterior portion of the drywell shell. The preventive action program element of the LRA AMP includes an enhancement to revise plant procedures to require inspection of the sand pocket drain lines prior to the period of extended operation. Also, the parameters monitored or inspected program element of the LRA AMP includes an enhancement to revise plant procedures to specify that inspections of sand pocket drain lines will monitor the internal condition of drain lines. Further, the detection of aging effects program element of the LRA AMP includes an enhancement to revise plant procedures to require visual inspection of sand pocket drain lines to ensure there is no evidence of blockage. Based on item 9 of LRA Section A.4, License Renewal Commitment List, these enhancements (i.e., Commitments No. 9a, 9d and 9e) are scheduled to be completed prior to the period of extended operation. The staff needs additional information to determine that these enhancements are consistent with the recommendations for BWR Mark I steel containments in the preventive actions and parameters monitored or inspected program elements of the GALL Report AMP because: (i) it is not clear if the intent of the license renewal commitments is to revise plant procedures prior to the period of extended operation or to revise plant procedures and perform inspections of drain lines prior to the period of extended operation; (ii) the proposed enhancements (i.e., Commitments No. 9a and 9d) do not provide a stated objective for the inspection (i.e., to ensure that drain lines are clear or to monitor for water leakage or moisture in the drains or both; based on description in the above mentioned program elements, they appear to be exclusively intended to ensure that sand pocket drain lines are clear); and (iii) the enhancements (i.e., Commitments No. 9a, 9d, and 9e) do not provide the associated frequency of inspections and the basis for its adequacy to meet the intended objective; and (iv) it is not clear to the staff as to how the LRA AMP ensures that the refueling seal drains are clear.
During refueling the refueling bellows drain empties into a manifold which is equipped with a sight glass. This sight glass is monitored when the refueling pool is flooded to detect potential leakage of water into the space around the drywell shell. The sand pocket drains are also [to] be monitored for signs of moisture. Fermi 2 plans to re-inspect the drain lines to verify their condition prior to the period of extended operation to confirm that these preventative actions
32 are not warranted. The program will be enhanced to require inspection of the sand pocket drain lines prior to the period of extended operation. (emphasis added)
Further, the parameters monitored or inspected program element on page 28 of the program basis document states that: Fermi 2 performs routine surveillances of the drains to record the observed condition of the drain lines for any leakage. Fermi 2 will inspect the sand pocket drain lines to verify their condition prior to the period of extended operation to confirm that the sand pocket drains are clear in ...
The parameters monitored or inspected program element of GALL Report AMP XI.S1 recommends that license renewal applicants with BWR Mark I steel containments should [periodically] monitor the sand pocket area drains and/or the refueling seal drains for water leakage.
During the audit, the staff reviewed Fermi 2 Surveillance Procedure 24.000.03, Revision 77 (including Attachments 1 and 2), and noted that the procedure includes the following regulatory commitments made by letter NRC-88-0081, Revised Response to GL 87-05, dated 4/20/88, and tracked in the applicants Regulatory Action Commitment Tracking System (RACTS) under RACTS 88027. These items require inspection of the reactor-drywell seal bellows and the four sand cushion drain lines for leakage during every refueling outage.
(a) Items (35.0 in Attachment 1 and 1.10 in Attachment 2 identified as commitments
[CM]) requiring verification that reactor-drywell seal bellows leakage is within limits.
The procedure requires this verification to be performed during Mode 5 Refueling on a daily basis for the first 3 days following reactor cavity flooding and at a frequency of 7 days following that with an acceptance criteria of no observed leakage; (b) Item (1.09 in Attachment 2 identified as commitment [CM]) requiring verification that drywell sand cushion leakage is within limits. The procedure requires this verification to be performed during Mode 5 Refueling at a frequency of 7 days (with a note that the commitment is monthly but performance will be 7 days) following reactor cavity flooding with an acceptance criteria of no observed leakage. Checks for leakage are required at Azimuth 90/180/270/360 6 below reactor pedestal catwalk between torus and drywell.
Despite the above existing commitments controlled by Procedure 24.000.03 to periodically monitor the sand pocket cushion drain lines and reactor-drywell seal bellows for signs of water leakage into inaccessible areas of the drywell, it is not clear to the staff if these periodic monitoring of the sand cushion drain lines and refueling seal bellows for water leakage every refueling outage will continue into the period of extended operation because of the inconsistent and contradicting statement (cited with emphasis added in the indented paragraph at the beginning of the bullet for this issue) on page 26 of the program basis document. Therefore, the staff needs additional information to determine if the parameters monitored or inspected program element is consistent with the GALL Report AMP with regard to the recommendation for periodically monitoring the sand pocket area drains and the refueling seal drains for water leakage.
- The monitoring and trending program element of the LRA AMP included the enhancement, Revise plant procedures to determine drywell shell thickness in the sand pocket areas before the period of extended operation. From the results, develop a corrosion rate to demonstrate that the drywell shell will have sufficient thickness to perform its intended function through the period of extended operation. The
33 corresponding program element in GALL Report AMP XI.S1 recommends that the applicant develop a corrosion rate that can be inferred from past ultrasonic testing (UT) examinations or establish a corrosion rate using representative alternate means and provide a technical basis based on the developed or established corrosion rate that the drywell will have sufficient thickness to perform its intended function through the period of extended operation. During the audit, the staff noted that, for reasons indicated in the letters NRC-87-005 and NRC-88-0081, dated September 10, 1987, and April 20, 1988, respectively, ultrasonic thickness measurements of the drywell shell sand pocket areas were not performed at Fermi 2 in response to Generic Letter 87-05. It is not clear to the staff if these statements are consistent because the proposed enhancement in the LRA AMP program basis does not indicate the minimum number of sets and interval at which UT measurements will be performed, and does not provide the technical basis of how an appropriate corrosion rate will be developed if only one set of UT measurements is intended.
- The corrective actions program element of the LRA AMP included an enhancement to revise plant procedures to require three specific corrective actions should moisture be detected or suspected in the inaccessible area on the exterior of the Mark I steel containment drywell shell. The staff noted that the specific actions included in the above enhancement to the LRA AMP correspond to recommended actions (b), (c), and (d) in the corrective actions program element of GALL Report AMP XI.S1 if moisture has been detected in the inaccessible area on the exterior of the Mark I containment drywell shell or the source of moisture cannot be determined subsequent to root cause analysis.
However, the LRA AMP program basis document and corresponding enhancement did not address action (a) of the GALL Report AMP which recommends including in the scope of license renewal any components that are identified as a source of moisture, if applicable, and performing aging management review. It is not clear to the staff that the corrective actions program element of the LRA AMP is consistent with recommended actions in the GALL Report AMP specifically applicable to inaccessible areas of the drywell shell exterior of Mark I containments because the LRA AMP basis document did not identify the components that are potential sources of moisture to inaccessible areas of the drywell exterior and whether they were subjected to AMR.
During the audit, the staff made the following observations:
- The staff reviewed the ISI-NDE Program Plan for Fermi 2, Part F, ASME Section XI Containment Inservice Inspection Program, Appendix F4.5, and noted that Fermi 2 has a proactive inspection program of the interior wetted surfaces of submerged areas of the torus and the vent header. The interior of the torus is inspected and repaired on an every other refueling outage basis. During these examinations, the submerged areas of the torus shell are cleaned from water line to water line to remove sludge and other foreign material, and then coating inspectors inspect the entire area by VT-3 visual inspection. All areas of broken blisters and mechanical damage exhibiting corrosion on the pressure boundary immersion area are repaired. Additionally, Fermi 2 monitors the blister condition on specific immersed areas of the torus chosen based on their relatively high number of indications. During each inspection, the size, population density and condition of the blisters are monitored and trended to identify and evaluate adverse trends.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by
34 known industry operating experience (e.g., no previously unknown aging effects were identified by the applicant or staff).
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR, noting that conforming changes may be required as a result of responses to potential RAI issues identified above.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.S1. The staff also identified certain aspects of the preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and corrective actions program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR, subject to conforming changes that may be required as a result of responses to the potential RAI issues.
LRA AMP B.1.13, Containment Leak Rate Summary of Information in the Application. The LRA states that AMP B.1.13, Containment Leak Rate, is an existing program that is consistent with the program elements in GALL Report AMP XI.S4, 10 CFR Part 50 Appendix J. To verify this claim of consistency, the staff audited the LRA AMP.

41 The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements.
During the audit, the staff verified that the scope of program, preventive actions, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP, as modified by LR-ISG-2011-03 and LR-ISG-2012-02. However, the staff found that, for the parameters monitored or inspected and detection of aging effects program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
- The parameters monitored or inspected and detection of aging effects program elements of the LRA AMP include an enhancement to revise program procedures to ensure that walkdowns will include inspections for leakage to detect cracking in stainless steel components exposed to air containing halides. However, some of the subject components have a gaseous internal environment. It is not clear to the staff how external leakage of the gas will be detected.
- LR-ISG-2012-02 revised GALL Report AMP XI.M36 to recommend inspections of thermal insulation when the insulation has a function to reduce heat transfer. The LRA AMP does not contain this activity. The applicants program basis document, FERMI-RPT-12-LRD03, states that thermal insulation is not credited for reduction of heat transfer. However, LRA Table 3.5.2-4 includes an AMR item for insulation with an intended function of heat transfer reduction, and the Structures Monitoring Program is proposed to manage loss of material and change in material properties. It is not clear to the staff whether the activities to inspect thermal insulation under the Structures Monitoring Program are consistent with those recommended in LR-ISG-2012-02.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR, as modified by LR-ISG-2012-02.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M36, as modified by LR-ISG-2011-03 and LR-ISG-2012-02. The staff also identified certain aspects of the parameters monitored or inspected and detection of aging effects program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
42 LRA AMP B.1.17, Fatigue Monitoring Summary of Information in the Application. The LRA states that AMP B.1.17, Fatigue Monitoring, is an existing program that, with enhancements and an exception, is consistent with the program elements in GALL Report AMP X.M1, Fatigue Monitoring. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP. The exception to the GALL Report AMP, which is not necessary for consistency with the GALL Report, will be evaluated in the SER.

The staff conducted its audit of LRA program elements one through six based on the contents of the existing program, as modified by the proposed enhancements. Aspects of the corrective actions program element of the LRA AMP associated with the exception were not evaluated during this audit. Aspects of this program element that are not associated with the exception were evaluated and are described below.
43 During the audit, the staff verified that the scope of program, preventive actions, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. The staff also verified that aspects of the corrective actions program element not associated with the exception are consistent with the corresponding program elements in the GALL Report AMP.
The staffs evaluation of aspects of the program element associated with the exception will be addressed in the SER. In addition, the staff found that for the parameters monitored or inspected program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subject discussed below.
- The parameters monitored or inspected program element of the LRA AMP states that the cycle counting method of fatigue monitoring will be used to track the number of occurrences for plant transients. The GALL Report AMP recommends tracking the number of each plant transient, although it does not provide guidance on the use of a specific fatigue monitoring method. The applicants Fatigue Monitoring Program is currently limited to cycle counting and does not allow for more detailed fatigue monitoring methods, such as Cycle-Based Fatigue and Stress-Based Fatigue, to prevent the fatigue design limit from being exceeded. It is not clear to the staff if fatigue monitoring methods other than Cycle Counting are being used to prevent the fatigue design limit of components from being exceeded.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. The staff also noted that the applicant tracks cumulative operating time on components in support of flaw evaluations. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subject discussed below.
- The applicants Fatigue Monitoring Program is limited to monitoring plant transients in order to remain below component design limits based on crack initiation. The applicant is currently tracking cumulative operating time on components in support of flaw evaluations. The applicants Fatigue Monitoring Program does not track usage time or support crack growth calculations. It is unclear if the TLAAs associated with these components can be tracked using the Fatigue Monitoring Program.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified that this description is consistent with the description provided in the SRP-LR, although information regarding the methodologies to implement the commitments was not available for review. In order to obtain the information necessary to verify the sufficiency of the UFSAR supplement commitments, the staff will consider issuing RAIs for the subject discussed below.
- The applicants Fatigue Monitoring Program contains enhancements to prevent the fatigue design limit of components from being exceeded when accounting for environmental effects. The UFSAR supplement contains a commitment (Commitment No. 12, part b) to calculate environmental correction factors in order to assess the impact of the reactor coolant environment on component fatigue life. As part of this
44 commitment, plant-specific component locations in the reactor coolant pressure boundary that lead the components identified in NUREG/CR-6260 will be identified for tracking purposes. It is unclear what methodology is being used to identify the plant-specific limiting locations.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, detection of aging effects, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP X.M1.
The staff also verified that for the acceptance criteria program element, the aspects of the LRA AMP program element not associated with the exception are consistent with the corresponding program element in GALL Report AMP X.M1. The staffs evaluation of aspects of the program element associated with exceptions will be addressed in the SER. The staff also identified certain aspects of the parameters monitored or inspected program element of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. However, the sufficiency of the AMP to track parameters other than transients, such as cumulative operating time, may require additional information. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR, although additional information regarding the methodologies being used to satisfy the aspects of the associated commitments may be requested.
LRA AMP B.1.18, Fire Protection Summary of Information in the Application. The LRA states that AMP B.1.18, Fire Protection, is an existing program with enhancements that is consistent with the program elements in GALL Report AMP XI.M26, Fire Protection. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP; however, it does not consider the sufficiency of enhancements which are not necessary for consistency, which will be evaluated in the SER.

During the audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP.
However, the staff found that for the detection of aging effects program element, additional information is necessary in order for the staff to complete its review; the staff will consider issuing RAIs for the subject discussed below.
- The staff noticed that the Aging Management Program Evaluation Report for Fire Protection, under the comparison statement for the Detection of Aging Effects program element, states that visual inspection of other fire barrier materials, including fire barrier dampers, is performed at a frequency in accordance with the technical requirements manual, which is every 18 months.
Consistent with the SRP-LR and the GALL Report, DTE selected the Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program and the External Surfaces Monitoring Program to manage for loss of material. The periodicity for the Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program is based on a sampling of at least 20 percent or maximum of 25 components every 10 years. Selection of the Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components Program may conflict with DTEs current requirement to inspect the fire damper housings every 18 months.
47 During the audit, the staff made the following observations:
- In Section 4.6 of FERMI-RPT-12-LRD03, under the Detection of Aging Effects element, it states that If any sign of degradation is detected within that sample, the scope of the inspection is expanded to include additional seals. This statement is consistent with the statement in GALL Report AMP XI.M26 for expansion of the sample. The staff noticed that Technical Requirements Manual (TRM) Section 3.12.8 (Technical Requirements Surveillance Requirement (TRSR) 3.12.8.7) states that if apparent changes in appearance or abnormal degradations are found, a visual inspection of an additional 10 percent of each type of sealed penetration shall be made, and that this inspection process shall continue until a 10 percent sample with no apparent changes in appearance or abnormal degradation is found. To show consistency with the GALL Report for this particular activity, DTE references Plant Technical Procedure - Fermi 2 28.507.05, Revision 19, Inspection of Penetration Fire Stops. General Requirement 5.1.1 states, in part, If changes in appearance from normal are found, a visual inspection of an additional 10 percent of that type of sealed penetration shall be made.
This inspection process shall continue until a 10 percent sample is found with no apparent changes in appearance or abnormal degradation.
- Enhancement No. 2 states that Fire Protection Program procedures will be revised to require visual inspections of in-scope fire wrap and fire stop materials constructed of fibersil cloth, cerafoam, kaowool, thermolag, flamemastic, and pyrocrete. The staff noticed that LRA Table 3.5.2-4 does not include cerafoam, kaowool, flamemastic or pyrocrete as materials. However, FERMI-RPT-12-AMC04 states that [m]aterial used for fire stops and fire wraps include carborundum durablankets, carborundum fibersil cloth, silicone fabric boot, silicone elastomers and steel. It is not clear if the applicant uses cerafoam, kaowool, flamemastic or pyrocrete in the plant as fire stop materials.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M26. The staff also identified certain aspects of the detection of aging effects program element of the LRA AMP for which additional information or additional evaluation is required before the staff can complete its review.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
48 LRA AMP B.1.19, Fire Water System Summary of Information in the Application. As amended by letter dated July 30, 2014, the LRA states that AMP B.1.19, Fire Water System, is an existing program with enhancements and exceptions that will be consistent with the program elements in GALL Report AMP XI.M27, Fire Water System, as modified by LR-ISG-2012-02, Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion under Insulation. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with LR-ISG-2012-02 AMP XI.M27 and exceptions to LR-ISG-2012-02 AMP XI.M27.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff conducted walkdowns of the general service water pump house and the fuel oil tank for the diesel-driven firewater pump.
The staff also conducted an independent search of the applicants operating experience database using the keywords: biofoul, biological, clog, silt, through-wall, and foul.

- 28. WO 38192166 04/22/2014 Test for Main Transformer 2B The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements. Aspects of the detection of aging effects program element of the LRA AMP associated with the exceptions were evaluated during this audit. Aspects of the program elements that are not associated with the exceptions were evaluated and are described below.
50 During the audit, the staff verified that the scope of program, preventive actions, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. The staff also verified that aspects of the detection of aging effects program element not associated with the exceptions are consistent with the corresponding program elements in the GALL Report AMP. The staffs evaluation of aspects of this program element associated with the exceptions will be addressed in the SER.
In addition, the staff found that for the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
- Enhancement Nos. 2 and 7 to the parameters monitored or inspected and detection of aging effects program elements of the LRA AMP state that an inspection of the wet fire water system piping condition will be conducted at least once every 5 years. The applicant will conduct the test by opening a flushing connection at the end of one main and by removing a sprinkler toward the end of one branch line. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in National Fire Protection Association (NFPA) 25 Section 14.2.2, the licensee inspect every other system in buildings with multiple wet pipe systems every 5 years. During the audit, the applicant confirmed that it has multiple wet pipe systems in buildings with in-scope components protected by the fire water system. The applicant did not provide a basis for why testing only one system every 5 years is sufficient.
- Enhancement No. 4 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that a basis for the acceptance criteria of less than or equal to 25 pounds per square inch gauge (psig) and less than or equal to 10 psig that currently exists in the main drain test procedures will be developed.
LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Section 13.2.5.2, a 10 percent reduction on full flow pressure during main drain tests should be corrected.
During the audit, the staff confirmed that the fire water system header pressure is 150 psig plus or minus 10 psig. While the less than or equal to 10 psig acceptance criterion could be conservative based on the 150 psig header pressure, it is not clear to the staff how a less than or equal to 25 psig criterion can be justified.
- Enhancement No. 6 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that sprinklers will be cleaned if obstructions are identified during internal inspections. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Section 5.2.1.1.2, licensee should replace corroded or loaded sprinklers. The applicant did not provide a basis for why corroded or loaded sprinklers can be cleaned versus replaced.
- Enhancement No. 11 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that an obstruction investigation will be conducted after an extended shutdown of more than one year. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Sections 14.2.1.3 and 14.3.1, there are additional criteria for conducting obstruction investigations (e.g., discharge of obstructive material during routine water tests, plugging of inspectors test connection, pinhole leaks). During the audit, the staff did not find any procedures that included the additional criteria, nor did the applicant provide a basis for why its enhancement is sufficient to ensure that obstruction investigations would be conducted when
51 appropriate. It is not clear to the staff that these statements are consistent because only one criterion to conduct an obstruction investigation is identified.
- Exception No. 7 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that a one-time inspection of the internal surfaces of the dry piping downstream of the manual isolation valve for the wet pipe system in the cable spreading room will be conducted. LR-ISG-2012-02 AMP XI.M27 recommends that a licensee should conduct periodic inspections of fire water system piping exposed to indoor air (see LRA Table 3.3.2-7). It is not clear to the staff that these statements are consistent because the applicant did not provide a basis for why there is reasonable assurance that the current licensing basis intended function(s) of the piping would be met when only a one-time inspection is conducted.
- Exception No. 7 to the detection of aging effects program element of the LRA AMP, as amended by letter dated July 30, 2014, states that in lieu of conducting a deluge test with air or smoke for the control center heating, ventilation, and air conditioning (HVAC) make-up filter charcoal filter absorber unit and the control center HVAC recirculation filter charcoal absorber unit, it will inspect the internal surfaces of the piping downstream of the manual isolation valves whenever the charcoal is replaced. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Section 13.4.3.2.2.4, a licensee should conduct deluge valve testing at least every 3 years. It is not clear to the staff that these statements are consistent because during the audit, the staff reviewed charcoal filter media replacement work orders and determined that media is replaced approximately every 7 to 10 years.
- The acceptance criteria program element of the LRA AMP, as amended by letter dated July 30, 2014, does not include an acceptance criteria associated with corrosion of sprinklers during periodic visual sprinkler inspections. LR-ISG-2012-02 AMP XI.M27 recommends that, as stated in NFPA 25 Section 5.2.1.1.2, licensees should replace sprinklers that exhibit corrosion. It is not clear to the staff that these statements are consistent because the Fire Water System Program does not include a criterion to replace corroded sprinklers and the applicant did not provide a basis for why corroded sprinklers can remain in service.
During the audit, the staff made the following observations:
- The staff reviewed procedure 23.501.01 and confirmed that there are seven main drain locations in the reactor building, two in the auxiliary building, three in the radwaste building, eight in the turbine building, three in the on-site storage facility, four in the residual heat removal building, and one in the general service water pump house. The staff also reviewed procedure 28.501.13 in conjunction with 23.501.01 and confirmed that the applicant conducts main drain tests in accordance with NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, at locations in the reactor building, auxiliary building, and general service water pump house building every 18 months.
- The staff reviewed CARD 08-23973. The CARD states that recent testing, May 2008, demonstrated that the C factor for the east and north portion of the header is approximately 59 and for the south and west portion of the header, the C factor is approximately 61. The previous test yielded C factors of 63 and 62 respectively. The design calculation uses a value of 60. CARD 01-24296 states that the May 2009 testing resulted in a C factor of 64. CARD 01-24296 also states that the applicant detected an error in the calculation of hydrant flows resulting in an average C factor increase of 3.6.
52 CARD 01-24296 further states that average C factor results are as follows: 66 in 2001, 61 in 2002, 63 in 2005, 57 in 2008, and 60 in 2009.
- The staff reviewed procedure 28.504.04 and confirmed that the applicant conducts a fire water system main header flow testing every 3 years.
- The staff reviewed procedure 28.501.10 and confirmed that the applicant conducts a flow confirmation at each hose station every 3 years.
- The staff reviewed procedure PST 1284705 and confirmed that the applicant tests the hydrogen seal oil unit deluge system every 364 days.
- The staff reviewed the Fire Protection System Design Basis Document and confirmed that the fire water system pressure at all automatic and manual water-based system points should be 150 psig plus or minus 10 psig.
- The staff reviewed procedure 28.504.06 and confirmed that the applicant conducts a flush of the yard piping every 12 months.
- The staff reviewed the corrective actions associated with CARD 04-23042, which documented silting in fire protection sprinkler piping, and confirmed that the degraded piping was associated with a warehouse supplied from Fermi Unit 1. The applicant flushed the piping to remove all debris and implemented a modification to supply the sprinklers from Fermi Unit 2. The staff noted that NFPA 25, Sections D.5, Flushing Procedures, cites flushing as an effective method to conduct obstruction investigations of yard mains, risers, feed mains, cross mains, and branch lines.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff). In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing an RAI for the subject discussed below.
- One of the plant-specific operating experience examples cited in the LRA describes fire suppression flow testing that demonstrated degrading conditions in the underground piping system. The applicant stated that it increased the frequency of testing and evaluation of this piping from 3 years, as required in the current licensing basis, to annual testing. Based on its review of corrective action reports that describe the trend of degradation, it is not clear to the staff why the increased frequency of testing should not be continued during the period of extended operation.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff found that sufficient information was not available to determine whether the description provided in the UFSAR supplement was an adequate description of the LRA AMP. In order to obtain the information necessary to verify the sufficiency of the UFSAR supplement program description, the staff will consider issuing RAIs for the subject discussed below.
- As amended by letter dated July 30, 2014, LRA Section A.1.19 states that [t]he Fire Water System Program manages loss of material for in-scope long-lived passive water-based fire suppression system components using periodic flow testing and visual inspections. LR-ISG-2012-02 Table 3.0-1 recommends that the UFSAR supplement summary description for the Fire Water System Program should also state that it manages fouling and flow blockage. Although LRA Section A.1.19 references fouling
53 and flow blockage, it is only in reference to conducting visual inspections and not all of the inspections and testing in the program. It is not clear to the staff that the applicants current licensing basis will be adequate during the period of extended operation if the Fire Water System Program UFSAR supplement does not state that the program manages fouling and flow blockage.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding program elements in LR-ISG-2012-02 AMP XI.M27. The staff also verified that for the detection of aging effects program element, the aspects of the LRA AMP program element not associated with the exception are consistent with the corresponding program element in LR-ISG-2012-02 AMP XI.M27. The staffs evaluation of aspects of the program element associated with exceptions will be addressed in the SER. The staff also identified certain aspects of the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements of the LRA AMP for which additional information or evaluation is required before consistency can be determined.
Based on this audit, the staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. In addition, the staff identified a need for additional information regarding the adequacy of the program description in the UFSAR supplement.
LRA AMP B.1.20, Flow-Accelerated Corrosion Summary of Information in the Application. The LRA states that AMP B.1.20, Flow-Accelerated Corrosion, is an existing program with enhancements that will be consistent with the program elements in GALL Report AMP XI.M17, Flow-Accelerated Corrosion, as modified by LR-ISG-2012-01, Wall Thinning Due to Erosion Mechanisms. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicants operating experience database using the keywords: cavitat, erosi, fac, flow accel, flow assist, impinge, through-wall, and wall-thinning.

During the audit, the staff verified that the preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. However, the staff found that for the scope of program program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
- The Flow Accelerated Corrosion Program includes safety-related components. Electric Power Research Institute (EPRI) guidelines in Nuclear Safety Analysis Center (NSAC)-202L, Recommendations for an Effective Flow Accelerated Corrosion Program, recommend that appropriate quality assurance be applied to all phases of the Flow Accelerated Corrosion Program. The current Flow Accelerated Corrosion Program allows projected wall thicknesses to be determined using a wear value that is calculated by the CHECWORKSTM computer software. The wall thickness projection ensures that a component will continue to meet the minimum wall thickness allowed by design codes until its next scheduled inspection. Fermi 2 currently classifies CHECWORKSTM as a Category B software, which should not be used for safety-related design activities. For safety-related components, it is not clear that only results from software classified as Category A will be used to demonstrate that the design wall thickness will be met at the
55 next refueling outage. Otherwise, the other options included in the Flow Accelerated Corrosion Program, which use wall thickness measurements based on an engineering evaluation of ultrasonic testing data, should be used for safety-related applications.
- Program Notebook PEP19, Flow-Accelerated Corrosion, contains a discussion for the inspection scope selection, which includes a Feedwater Heater Shell Susceptibility Review. However, in its review of LRA Tables 3.4.2-2, Feedwater and Standby Feedwater System, and 3.4.2-3-2, Condensate System, Nonsafety-Related Components Affecting Safety-Related Systems, that contain the feedwater heaters, the staff could not identify any heat exchanger items for the feedwater heater shell that are managed by the Flow Accelerated Corrosion Program. Therefore, it is not clear as to how the effects of aging will be adequately managed for these components.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff).
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified that this description is consistent with the description provided in the SRP-LR, as modified by LR-ISG-2012-01.
Audit Results. Based on this audit, the staff verified that the preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M17, as modified by LR-ISG-2012-01. The staff also identified certain aspects of the scope of program program element of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR, as modified by LR-ISG-2012-01.
LRA AMP B.1.21, Inservice Inspection Summary of Information in the Application. The LRA states that AMP B.1.21, Inservice Inspection, is an existing program that is consistent with the program elements in GALL Report AMP XI.M1, ASME Section XI Inservice Inspection, Subsections IWB, IWC and IWD. To verify this claim of consistency, the staff audited the LRA AMP.

During the audit, the staff verified that the monitoring and trending and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the scope of program, preventive actions, parameters monitored or inspected and detection of aging effects program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
- The GALL Report AMP states that the scope of the program includes high-strength structural bolting. The GALL Report AMP preventive actions program element recommends using bolting material that has an actual measured yield strength of less than 150 kilopounds per square inch (ksi). The GALL Report AMP parameters monitored or inspected program element also recommends that high-strength structural bolting (actual measured yield strength greater than or equal to 150 ksi) in sizes greater than 1 inch nominal diameter, susceptible to stress corrosion cracking be monitored for cracking. In addition, the GALL Report AMP detection of aging effects program element recommends that, for high-strength structural bolting (actual measured yield strength greater than or equal to 150 ksi) in sizes greater than 1 inch nominal diameter, volumetric examination be performed to detect cracking. It is not clear that the Inservice Inspection-IWF Program is consistent with the GALL Report AMP because, based on its review of the LRA and associated AMP basis documents, the staff found no mention of the GALL Report AMP XI.S3 recommendations in the preventive actions, parameters monitored or inspected, and detection of aging effects program elements recommendations described above. In addition, for the scope of program program element it is not clear if there are high-strength structural bolts (actual measured yield strength greater than or equal to 150 ksi) in sizes greater than 1 inch nominal diameter within the scope of the Inservice Inspection-IWF Program.
During the audit, the staff made the following observations:
60
- The Inservice Inspection-IWF Program basis document states that Fermi 2 does not have ASME Code Section XI, Subsection IWF vibration isolation supports. The staff performed a database search using the keyword vibration isolator and found no vibration isolation supports within the scope of the Inservice Inspection-IWF Program.
- LRA Table 3.5.1, item 3.5.1-75, addresses sliding surfaces of column base plates that rest on Lubrite pads exposed to air - indoor uncontrolled. The LRA states that [l]ubrite plates are not subject to aging management because the listed aging mechanisms are event driven and typically can be avoided though proper design. The staff reviewed the applicants claim and noted that the applicant has not screened in any sliding surfaces with Lubrite within the scope of license renewal. During the audit, the staff performed a search of the applicants operating experience database and found no results for the keyword Lubrite.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. The staff also determined that the operating experience provided by the applicant and identified by the staffs independent database search is not sufficient to allow the staff to verify that the LRA AMP, as implemented by the applicant, is sufficient to detect and manage the effects of aging. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subjects discussed below.
- ASME Code Section XI, Subsection IWF, states, that to the extent practical, the same supports selected for examination during the first inspection interval shall be examined during each successive inspection interval. Recent industry operating experience has revealed situations in which supports within the IWF sample were degraded, but did not meet the IWF threshold for repair. The supports were reworked to as-new condition and remained in the IWF sample. The staffs concern with respect to aging management is that if ASME Code,Section XI, Subsection IWF supports that are part of the inspection sample are reworked to as-new condition, they are no longer typical of the other supports in the population. Subsequent ASME Code,Section XI, Subsection IWF inspections of the same sample would not represent the age-related degradation of the rest of the population. The LRA and the associated basis documents provided no discussion of how this issue would be addressed.
- The LRA states that [p]lant procedures prohibit the use of lubricants containing molybdenum disulfide. GALL Report AMP XI.S3 preventive action program element states that molybdenum disulfide should not be used as a lubricant due to its potential contribution to SCC, especially for high-strength bolts. During the audit, the staff was able to confirm that plant procedures inhibit the use of molybdenum disulfide lubricants; however, it is not clear whether molybdenum disulfide lubricants have been used at Fermi 2 before plant procedures were revised to prohibit their use. If these lubricants have been used, the staff needs additional information regarding what will be done to age manage structural bolts lubricated with molybdenum disulfide.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR. The staff found that sufficient information was not available to determine whether the description provided in the UFSAR supplement was an adequate description of the LRA AMP.
61 Audit Results. Based on this audit, the staff verified that the monitoring and trending and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.S3. The staff also identified certain aspects of the scope of program, preventive actions, parameters monitored or inspected, and detection of aging effects program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.23, Inspection of Overhead Heavy Load and Light Load (Related to Refueling) Handling Systems Summary of Information in the Application. The LRA states that AMP B.1.23, Inspection of Overhead Heavy Load and Light Load (Related to Refueling) Handling Systems, is an existing program with enhancements that is consistent with the program elements in GALL Report AMP XI.M23, Inspection of Overhead Heavy Load and Light Load (Related to Refueling) Handling Systems. To verify this claim of consistency, the staff audited the LRA AMP. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP.

LRA AMP B.1.24, Internal Surfaces in Miscellaneous Piping and Ducting Components Summary of Information in the Application. The LRA states that AMP B.1.24, Internal Surfaces in Miscellaneous Piping and Ducting Components, is a new program that will be consistent with the program elements in GALL Report AMP XI.M38, Inspection of Internal Surfaces in Miscellaneous Piping and Ducting Components, as modified by LR-ISG-2012-02, Aging Management of Internal Surfaces, Fire Water Systems, Atmospheric Storage Tanks, and Corrosion under Insulation. To verify this claim of consistency, the staff audited the LRA AMP.
At the time of the audit, the applicant had not yet fully developed the documents necessary to implement this new program, and the staffs audit addressed only the program elements described in the applicants program basis document.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicants operating experience database using the keywords: rust, pit, corros, leak, microbiologi, min wall, MIC, and wastage.
The table below lists the documents that were reviewed by the staff and were found relevant to the audit. These documents were provided by the applicant or were identified in the staffs search of the applicants operating experience database.

64 Although the staff verified the program elements to be consistent with those in GALL Report AMP XI.M38, the staff noted an issue that may require an RAI for clarification.
- The applicants program manages reduction of heat transfer due to fouling for heat exchanger tubes and fins exposed to various air environments, as listed in LRA Table 3.3.2-11. Based on discussions during the audit, some of the associated components are related to room coolers that are within the scope of GL 89-13, Service Water System Problems Affecting Safety-Related Equipment. The staff noted that GL 89-13 expects heat exchangers to be tested or inspected at least every 5 years, whereas the Internal Surfaces in Miscellaneous Piping and Ducting Components Program includes only a 20 percent sample that is inspected every 10 years. Therefore, it is not clear whether implementation of the Internal Surfaces in Miscellaneous Piping and Ducting Components Program would relax existing current licensing basis inspections for these room coolers.
The LRA states that the program is new and therefore provides no operating experience associated with the program. The operating experience basis document, FERMI-RPT-12-LRD09, states that a search of operating experience associated with ducts and housings did not identify any aging effects beyond those identified in the GALL Report. During the audit of the operating experience program element, the staffs independent database search did not identify any plant-specific operating experience that would indicate that the program is not capable of managing the effects of aging for components within the programs scope.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR, as modified by LR-ISG-2012-02.

The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements.
During the audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the acceptance criteria program element, sufficient information was not available to determine whether it was consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing RAIs for the subject discussed below.
- The acceptance criteria program element of the LRA AMP basis document (FERMI-12-LRD05, Section 3.5) states that potential non-conforming conditions identified during the course of an inspection are noted and evaluated and corrective action will be taken as necessary. Section 4.0 of procedure MMR14 is referenced as the
66 basis. This section provides qualitative criteria, described in terms of structural function only, for evaluation of inspection results. The GALL Report AMP states that the extent of observed shrinkage and/or separation and cracking of masonry may not invalidate the evaluation basis or impact the walls intended function. It recommends that further evaluation is conducted if the extent of cracking and loss of material is sufficient to impact the intended function of the wall or invalidate its evaluation basis. It is not clear to the staff that this element of the LRA AMP is consistent with the recommendations in GALL Report AMP XI.S5 because the LRA acceptance criteria do not appear to address the invalidate evaluation basis aspect of the GALL Report acceptance criteria.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff).
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.S5. The staff also identified certain aspects of the acceptance criteria program element of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.26, Metal Enclosed Bus Inspection Summary of Information in the Application. The LRA states that AMP B.1.26, Metal Enclosed Bus Inspection, is a new program that is consistent with the program elements in the GALL Report AMP XI.E4, Metal Enclosed Bus. To verify this claim of consistency, the staff audited the LRA AMP. At the time of the audit, the applicant had not yet fully developed the documents necessary to implement this new program, and the staffs audit addressed what was in the applicants basis document, FERMI-RPT-12-LRD04, Metal Enclosed Bus Inspection. Issues identified but not resolved in this report will be addressed in the SER.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff conducted walkdowns of the 120 kV switchyard, including the in-scope metal enclosed bus installed between CTG transformer CTG 11-1 and peaker bus 1-2b. The staff also conducted an independent search of the applicants operating experience database using the keywords: metal enclosed bus, loose connections, and water intrusion.

During the audit, the staff verified that the scope of program, preventive actions, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the bases documents are consistent with the corresponding elements of GALL Report AMP XI.E4, Metal Enclosed Bus.
For the parameters monitored or inspected program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing an RAI for the subject discussed below.
- GALL Report AMP XI.E4, Metal Enclosed Bus, program element parameters monitored or inspected states that the external portions of the metal enclosed bus, including accessible gaskets, boots, and sealants, are inspected for hardening and loss of strength due to elastomer degradation. The detection of aging effects program element states that accessible elastomers (e.g., gaskets, boots, and sealants) are inspected for degradation including surface cracking, crazing, scuffing, dimensional change, (e.g., ballooning and necking), shrinkage, discoloration, hardening, and loss of strength.
- Basis Document Fermi RPT-12-LRD04 Metal Enclosed Bus Inspection, states that it is a new condition monitoring program that is consistent with GALL Report AMP XI.E4, Metal-Enclosed Bus.
- The staff reviewed the AMP basis document program element parameters monitored or inspected and it is not clear to the staff that the program element of the LRA AMP is consistent with the recommendation in the GALL Report AMP since there was no mention of the aging effects of elastomers in the proposed program element. The GALL Report AMP program element states that the external portions of the metal enclosed bus be inspected for hardening and loss of strength due to elastomer degradation.
68 In the LRA, the applicant stated that there is no operating experience at Fermi 2 involving the aging effects managed by this program. The applicant did not identify any operating experience for this program. During the audit of the operating experience program element, the staffs independent database search did not find any operating experience that would not be bounded by known industry operating experience.

For the parameters monitored or inspected and detection of aging effects program elements sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subject(s) discussed below.
- The applicant stated that one method of testing cable connections relied upon for maintenance is the use of thermography (infrared inspection). The staff reviewed the applicants thermography procedure 47.000.88. It is not clear to the staff that the thermography inspections are directed to take place under normal full load conditions of the affected electrical connections.
- It is not clear to the staff as to whether the representative sample designated by the applicant adequately addresses the various connection types noted by the staff (per Spec. No. 3071-128-EQ).
- Maintenance Procedures 35.301.001 and 35.301.001 provide values for checking the connection tightness by providing electrical connection torque values. It is not clear to the staff that these procedures are consistent with EPRI Guidance (EPRI TR-104213, Bolted Joint Maintenance & Applications Guide) concerning re-torqueing of electrical connections.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff). A total of 57 work orders were identified. The review of the identified items did not reveal any significant or unusual operating experience issues.
During the staff walkdown, the staff identified concerns with cable connection maintenance. In order to obtain the information necessary to determine whether the applicants operating experience supports the sufficiency of the LRA AMP, the staff will consider issuing RAIs for the subject(s) discussed below.
- During the electrical connection walkdown, the staff noted two 3000 amp/1200 amp bus tap boxes located in the Division 2 ESS 4160 V and 480 V switchgear room. It is not clear to the staff whether the connections inside these tap boxes are inspected under the current preventive maintenance procedures. These connections are within the scope of license renewal. The staff is concerned that if the in-scope tap box connections are not inspected or tested under current plant maintenance programs, then a one-time test under LRA AMP B.1.28 performed on a sampling basis may not be adequate to ensure
72 that either aging of metallic cable connections is not occurring and/or that the existing preventive maintenance program is effective such that a periodic inspection program is not required.
- It is not clear to the staff what routine maintenance is currently performed on the in-scope safety related 4160 V bus (including low side connections of transformer SS #65) electrical connections. The staff concern is that a one-time test under LRA AMP B.1.28 performed on a sampling basis may not be adequate to ensure that either aging of metallic cable connections is not occurring and/or that the existing preventive maintenance program is effective such that a periodic inspection program is not required.
- During the electrical connection walkdown of the 345 kV recovery path, a large number of birds were observed on the cable bus (Calvert bus) installed from SS #65 transformer to 4160 V bus 65 in the auxiliary building. This cable bus is depicted on one-line diagram 6SD721-2500-01 and drawing 6E721-2988-02. The staff is concerned that this cable bus can experience accelerated degradation due to bird debris.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR for a one-time inspection.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.E6. The staff also identified certain aspects of the parameters monitored or inspected and detection of aging effects program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also found that additional information is required before a determination can be made regarding whether the applicants operating experience supports the sufficiency of the LRA AMP. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.

Aspects of the detection of aging effects program element of the LRA AMP associated with the exception were not evaluated during this audit. Aspects of this program element that are not associated with the exception were evaluated and are described below.
88 During the audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. The staff also verified that aspects of the detection of aging effects program element not associated with the exception are consistent with the corresponding program elements in the GALL Report AMP.
The staffs evaluation of aspects of this program element associated with the exception will be addressed in the SER.
In addition, the staff found that for the monitoring and trending program element associated with the program enhancement, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing RAIs for the subject discussed below.
- The program enhancement states that the applicant will revise its procedures to ensure that new fluence projections through the period of extended operation and the latest vessel beltline adjusted reference temperature tables are provided to the Boiling Water Reactor Vessel Internals Project prior to the period of extended operation (i.e., prior to September 20, 2024). The staff noted that the applicants program is an existing program and upon receipt of renewed license the program should continue to provide adequate fracture toughness and dosimetry data throughout the license renewal term.
However, the LRA states that the applicants enhancement will be implemented prior to the period of extended operation, but not within a specific time period upon receipt of renewed license. The staff finds that the enhancement regarding data sharing is important to maintain the effectiveness of the Integrated Surveillance Program (ISP) and, therefore, it is necessary to implement the program enhancement within a specific time period upon receipt of renewed license unless adequate justification is provided.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff).
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff found that sufficient information was not available to determine whether the description provided in the UFSAR supplement was an adequate description of the LRA AMP. In order to obtain the information necessary to verify the sufficiency of the UFSAR supplement program description, the staff will consider issuing RAIs for the subject discussed below.
- As previously discussed, the monitoring and trending program element is associated with the program enhancement. The staff finds that it is necessary to revise the description of the program enhancement in the UFSAR supplement in such a manner to implement the enhancement within a specific time period upon receipt of renewed license unless adequate justification is provided.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M31. The staff also verified that for the detection of aging effects program element, the aspects of the LRA AMP program element not associated with the exception are consistent
89 with the corresponding program element in GALL Report AMP XI.M31. The staffs evaluation of aspects of the program element associated with the exception will be addressed in the SER.
The staff also identified certain aspects of the monitoring and trending program element of the LRA AMP associated with the program enhancement, for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff identified a need for additional information regarding the adequacy of the program description in the UFSAR supplement.
LRA AMP B.1.39, RG 1.127, Inspection of Water-Control Structures Associated with Nuclear Power Plants Summary of Information in the Application. The LRA states that AMP B.1.39, RG 1.127, Inspection of Water-Control Structures Associated with Nuclear Power Plants, is an existing program with enhancements that will be consistent with the program elements in GALL Report AMP XI.S7, RG 1.127, Inspection of Water-Control Structures Associated with Nuclear Power Plants. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant.

During the audit, the staff verified that the scope of program, preventive actions, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
91
- The parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements of GALL Report AMPs XI.S6 and XI.S7, explicitly address the aging management of high-strength (measured yield strength greater than or equal to 150 ksi) structural bolts greater than 1 inch in diameter. The GALL Report recommends that visual inspections of high-strength structural bolts be supplemented with volumetric or surface examinations to detect cracking. It is not clear if there are high-strength structural bolts used in Fermi 2 structures (other than ASTM A325, F1852, and A490 used in civil structures) and, if used, whether the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements of LRA Sections B.1.42 and B.1.39, are consistent with the recommendations in GALL Report AMPs XI.S6 and XI.S7 regarding the provision to monitor for stress corrosion cracking in high-strength structural bolts greater than 1 inch in diameter through supplemental volumetric or surface examinations to detect cracking.
- The detection of aging effects program element of the LRA AMP states that inspection of water-control structures will be performed on an interval not to exceed 5 years. The GALL Report AMP recommends periodic inspections to be performed at least once every 5 years. The GALL Report also recommends that the program should include provisions for increased inspection frequency if the extent of the degradation is such that the structure or component may not meet its design basis if allowed to continue uncorrected until the next normally scheduled inspection. It is not clear to the staff that the detection of aging effects program element is consistent with the recommendations in GALL Report AMP XI.S7 because no discussion regarding the provision for increased inspection frequency was provided by the applicants AMP.
- As described in the LRA AMP program description in relation to the detection of aging effects program element, the program performs periodic visual examinations to monitor the condition of water-control structures and structural components, including steel piles required for the stability of the shore barrier. The GALL Report AMP recommends visual inspections to detect degradation of water-control structures. However, during its onsite audit, the staff noted that the applicant does not plan to perform visual inspections of the submerged steel piles at the shore barrier. It is not clear how the effects of aging of the steel piles will be adequately managed during the period of extended operation.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.S7. The staff also identified certain aspects of the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
92 LRA AMP B.1.40, Selective Leaching Summary of Information in the Application. The LRA states that AMP B.1.40, Selective Leaching, is a new program that will be consistent with the program elements in GALL Report AMP XI.M33, Selective Leaching. To verify this claim of consistency, the staff audited the LRA AMP. At the time of the audit, the applicant had not yet fully developed the documents necessary to implement this new program, and the staffs audit addressed only the program elements described in the applicants Aging Management Program Evaluation Report.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. The staff also conducted an independent search of the applicants operating experience database using the keywords: dealloy, dealum, dezinc, degraph, leach, and graphit.
The table below lists the documents that were reviewed by the staff and were found relevant to the audit. These documents were provided by the applicant or were identified in the staffs search of the applicants operating experience database.

CARD 06-27257 11/10/2006 Evaluate OE 23553 on BNL Inline check valves During the audit of program elements one through six, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. The staff determined that the lack of relevant operating experience identified by the applicant and confirmed by the staffs independent database search is sufficient to allow the staff to verify that the LRA AMP, when implemented by the applicant, will be sufficient to detect and manage the effects of aging.
During the audit of operating experience program element, the staff made the following observation:
- The staff reviewed CARD 06-27257 documenting the licensees response to an industry operating experience report regarding wall thinning and porosity due to de-aluminification (i.e., selective leaching) of inline check valves operating in the service
93 water system and constructed of aluminum bronze. In response to this report, the licensee conducted a component search and identified 8 similar components and found that they are not susceptible to the same kind of failure due to being constructed of stainless steel and installed in a clean air application.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.33.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
LRA AMP B.1.41, Service Water Integrity Summary of Information in the Application. The LRA states that AMP B.1.41, Service Water Integrity, is an existing program with enhancements that is consistent with the program elements in GALL Report AMP XI.M20, Open-Cycle Cooling Water System. To verify this claim of consistency, the staff audited the LRA AMP. Issues identified but not resolved in this report will be addressed in the SER. The scope of this audit report includes enhancements necessary to make the LRA AMP consistent with the corresponding GALL Report AMP.
Audit Activities. During its audit, the staff interviewed the applicants staff and reviewed onsite documentation provided by the applicant. In addition, the staff inspected portions of the emergency equipment service water, residual heat removal service water, and the emergency diesel generator service water systems within the RHR complex.

E1156 B001A, B, & Maintenance Strategy for RHR Mechanical Draft Cooling 5/22/2014 B002A, B Towers, SE, SW, NE, NW The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements. During the audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. However, the staff found that for the detection of aging effects program element, sufficient information was not available to determine whether it was consistent with the corresponding program element of the GALL Report AMP. In order to obtain the information necessary to verify whether this program element is consistent with the corresponding program element of the GALL Report AMP, the staff will consider issuing an RAI for the subject discussed below.
- For the detection of aging effects program element, FERMI-RPT-12-LRD03, Aging Management Program Evaluation Report, Non-Class 1 Mechanical, Section 4.12, Service Water Integrity, states that the program manages loss of material for components and fouling of heat exchangers. It is not clear whether the LRA identifies all of these aging effects because, in addition to fouling of heat exchangers, the applicant has detected fouling of spray nozzles in the RHR cooling towers. LRA Table 3.3.2-3, Service Water Systems, lists loss of material as the only aging effect for these nozzles.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff).
95 The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified that this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.M20.

- 16. Baseline Structures Inspection Report 04/16/1997 The staff conducted its audit of LRA program elements one through six based on the contents of the existing program as modified by the proposed enhancements.
During the audit, the staff verified that the scope of program and monitoring and trending program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. In addition, the staff found that for the preventive actions, parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements, sufficient information was not available to determine whether they were consistent with the corresponding program elements of the GALL Report AMP. In order to obtain the information necessary to verify whether these program elements are consistent with the corresponding program elements of the GALL Report AMP, the staff will consider issuing RAIs for the subjects discussed below.
- The preventive actions, parameters monitored or inspected, and detection of aging effects program elements of GALL Report AMP XI.S6 explicitly address the aging management of ASTM A325, ASTM F1852, and ASTM A490 structural bolting. The staff noted that the corresponding elements, with enhancements, of the LRA AMP basis document address ASTM A325 and A490 bolting, but made no mention of ASTM F1852 bolting. It is not clear to the staff that the above mentioned program elements of the LRA AMP are consistent with the recommendations in the GALL Report AMP because there was no mention of ASTM F1852 bolting.
- The preventive actions, parameters monitored or inspected and detection of aging effects program elements of the GALL Report AMP recommends monitoring
97 high-strength bolting greater than 1 inch in diameter for stress corrosion cracking and supplementing visual inspection with volumetric or surface examinations to detect SCC.
The corresponding program elements of the LRA AMP basis document for the Structures Monitoring Program state that plant procedures prevent the use of molybdenum disulfide as a lubricant for bolting, and therefore [high-strength] structural bolting is not susceptible to SCC. This explanation seems to be used as the basis for not supplementing visual examinations of high-strength bolting greater than 1 inch in diameter with volumetric or surface examination as recommended in the GALL Report AMP. The staff notes that the use of molybdenum disulfide is not the only contributor to SCC of high-strength bolts. Also, it is not clear from the LRA program basis document whether high-strength structural bolts are used in Fermi 2 structures and whether molybdenum disulfide lubricants have been used at Fermi 2 before plant procedures were revised to prohibit its use. The staff needs additional information to verify consistency with the GALL Report AMP because is not clear if there are high-strength structural bolts used in Fermi 2 structures and, if used, whether the program elements are consistent with the recommendations in GALL Report AMP XI.S6 and XI.S7 regarding the provision to monitor for SCC through supplemental volumetric or surface examinations to detect cracking.
- The detection of aging effects program element in the LRA AMP basis document states that underground (inaccessible areas) of concrete structures are subject to an aggressive groundwater/soil environment. The GALL Report AMP recommends a plant-specific program to manage concrete aging effects for inaccessible areas subject to an aggressive groundwater/soil environment. The detection of aging effects program element of the LRA AMP includes an enhancement to revise plant procedures to perform opportunistic inspections of inaccessible areas if it becomes accessible for some reason, and additionally, perform inspections of inaccessible areas in environments where observed conditions in accessible areas exposed to the same environment indicate significant degradation. The staff needs additional information to verify consistency with the GALL Report for the detection of aging effects in inaccessible, below-grade concrete structural elements exposed to an aggressive groundwater/soil environment because the proposed enhancement to the Structures Monitoring Program does not appear to be consistent with the GALL Report recommendations for either an aggressive or non-aggressive water/soil environment.
Further, the enhancement for inspections of inaccessible areas based on observations of accessible areas with the same environment appears to limit the scope of inaccessible areas that will be inspected because certain environment conditions may not exist for both accessible and inaccessible areas (i.e., a soil type environment may exist for an inaccessible area and not for an accessible area).
- The LRA AMP includes enhancements to the parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements to revise procedures to meet the guidelines provided in American Concrete Institute (ACI) 349.3R to demonstrate consistency with the GALL Report with regard to selection of parameters monitored, personnel qualifications requirements, and prescribing quantitative acceptance criteria. The program basis document for the LRA AMP references the 1996 edition of ACI 349.3R. However, the GALL Report AMP XI.S6 is based on, and references, the 2002 edition of ACI 349.3R. It is not clear to the staff that the use of the 1996 edition of ACI 349.3R is consistent with the GALL Report because there are substantive differences between the 2002 edition and 1996 edition of ACI 349.3R that introduce potential inconsistencies.
98 During the audit, the staff made the following observations:
- The staff performed a walkdown of the turbine building basement and observed leaching of concrete. The staff reviewed CARD Nos. 10-22385, 12-27792, and 09-26756, which document the presence of leaching in the RHR complex, auxiliary building basement, and reactor building sub-basement. The applicant determined that leaching is due to groundwater in-leakage and that the identified condition does not affect the structural integrity of the structures. However, there is no discussion in LRA AMP operating experience about leaching issues identified at the plant and no discussion about the evaluation performed that documents the impact of observed leaching on the intended function of the concrete and rebar. Additionally, the staff is not clear how LRA Table 3.5.1, item 47, which states that leaching has not been observed on accessible portions of concrete at Fermi 2, is consistent with the GALL Report recommendation when the operating experience provided by the applicant during the audit documents the presence of leaching in structures.
- During the staffs independent database search of operating experience, the staff reviewed CARD No. 13-25947 and noted that the applicant practice to reject concrete with air entrainment outside the 4.5 percent to 7.5 percent range due to inadequate air entrainment content is consistent with the GALL Report recommendation of adequate air content for concrete exposed to cycles of freezing and thawing. The SRP-LR states that the Structures Monitoring Program may not be sufficient to manage loss of material and cracking due to freeze-thaw for plants located in moderate to severe weathering conditions. However, a plant-specific program is not required if documented evidence confirms that the existing concrete has air content between 3 and 8 percent and inspections have not identified degradation related to freeze-thaw.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience (e.g., no previously unknown or recurring aging effects were identified by the applicant or staff).
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, and monitoring and trending program elements of the LRA AMP are consistent with the corresponding program elements in GALL Report AMP XI.S6. The staff also identified certain aspects of the preventive actions, parameters monitored or inspected, detection of aging effects, and acceptance criteria program elements of the LRA AMP for which additional information or additional evaluation is required before consistency can be determined.
Based on this audit, the staff also verified that the operating experience at the plant is bounded by the operating experience for which the GALL Report program was evaluated. In addition, the staff verified that the description provided in the UFSAR supplement is consistent with the description provided in the SRP-LR.
99 LRA AMP B.1.43, Water Chemistry Control - BWR Summary of Information in the Application. The LRA states that AMP B.1.43, Water Chemistry Control - BWR, is an existing program that is consistent with the program elements in GALL Report AMP XI.M2, Water Chemistry.

During the audit, the staff made the following observation:
- In Section 4.13 of Fermi-RPT-LRD03, Revision 2, the applicant refers to its commitment to implement the BWROG [boiling water reactor owners group] Chemistry Guidelines.
In the UFSAR, it states that the Water Chemistry Program is based on General Electric Water Quality Document 22A2747. In addition, the UFSAR states that the licensee conforms to Regulatory Guide 1.56, which, although it has been withdrawn by the NRC, endorsed BWRVIP-130. However, in the LRA, the applicant states that it is consistent with GALL Report AMP XI.M2, which recommends the use of BWRVIP-190. Based on this information, the staff was unclear about whether the applicant is currently using BWRVIP-190.
- The applicant explained that General Electric Water Quality Document 22A2747 was the early basis for the Fermi 2 Water Chemistry Program. Later, the BWR Owners Group developed guidelines for BWR plant water chemistry. Such guidelines are now issued through the BWRVIP program. BWRVIP-130, which was issued in 2004, was subsequently modified and issued as EPRI 1016579, otherwise known as BWRVIP-190: BWR Vessel and Internals Project, BWR Water Chemistry Guidelines 2008 Revision.
- The staff reviewed the Fermi 2 Water Chemistry Specifications and the Strategic Water Chemistry Plan. The staff noticed that these documents contain the guidance, needed statements, good practices, and Action Levels recommended in BWRVIP-190. The staff confirmed that the applicants Water Chemistry Control - BWR Program is consistent with the guidance in BWRVIP-190, and therefore, is consistent with GALL Report AMP XI.M2.
101 During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience.
The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.

During the audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and trending, and acceptance criteria program elements of the LRA AMP are consistent with the corresponding elements of the GALL Report AMP. During its review, the staff noted that the water testing frequency for the control center heating, ventilation, and air conditioning chill water system is currently done annually, whereas the GALL Report AMP states that the testing frequency should not be greater than quarterly unless justified with an additional analysis. Although the program basis documentation did not address this difference, the staff concluded that the difference between the current testing frequency and the frequency recommended in the GALL Report AMP would be resolved during implementation of the enhancement.
During the audit of the operating experience program element, the staffs independent database search found that the operating experience provided by the applicant is bounded by known industry operating experience. The staff also audited the description of the LRA AMP provided in the UFSAR supplement. The staff verified this description is consistent with the description provided in the SRP-LR.
Audit Results. Based on this audit, the staff verified that the scope of program, preventive actions, parameters monitored or inspected, detection of aging effects, monitoring and
