The fire pump diesel fuel oil tanks and the EDG day tanks are not currently subjected to internal inspections. An inspection frequency cannot be firmly established until the internal condition of these tanks is baselined. JAFNPP therefore plans to inspect these tanks on an eight year frequency similar to the EDG underground storage tanks. This frequency is based on the past inspection results of the EDG underground fuel oil storage tanks which have not indicated significant degradation while exposed to the same internal fuel oil environment. | |||
If initial inspections find unexpected conditions the frequency will be adjusted via the corrective action process. | |||

There were two less prevalent issues identified in 2000 assessment. The Surveillance Test Program and the Corrective Action Program (CAP) were issues that resulted in effectiveness reviews being conducted for both programs. Corrective actions were initiated to correct and improve both programs. Several ESW Condition Reports issued prior to 2000 required adjustments in significant level and closure of corrective actions. All issues identified regarding the CAP have been addressed. | |||
Additionally, all issues associated with the Surveillance Test Program have been addressed and included in the creation of a Surveillance Program Coordinator and a Surveillance Program Round Table. | |||
Several NRC inspections confirm that the strength of the significant improvements made within the ESW system. Integrated Inspection Report 05000333/2003008 is one example. During the ESW and support systems review, the ESW system was heavily scrutinized. The inspection reviewed open work requests, temp mods, and operator workarounds to assess the collective impact on system operation. The inspection reviewed the condition report database to verify that equipment alignment problems were being identified and appropriately resolved. No findings of 45 | |||

replaced bellows received metallurgical analysis. | |||
Analysis results from a couple of examples determined the presence of corrosive products, such as magnesium salts, chlorides, fluorides, and sulfides. Also, these corrosive species are not typical of containment operating conditions. As a result, the SER concludes the corrosive species, leading to the site specific degradation of the bellows, were most probably introduced during plant construction. (Reference Dresden/Quad Cities SER pages 3-403 to 3-408) | |||
Cracking due to SCC for the JAFNPP containment bellows is not an aging affect requiring management. There is no JAFNPP site-specific operating experience similar to that of Dresden/Quad Cities. In summary, the presence of corrosive contaminants is necessary for SCC to occur. The normal environment for the JAFNPP drywell is dry and there has been no indication of contamination of the bellows during construction. In addition, containment bellows for JAFNPP are not exposed to a corrosive environment. As such, SCC is not applicable to JAFNPP stainless steel bellows. (Ref. LRA paragraph 3.5.2.2.1.7) | |||
There is nothing to indicate that the bellows have been or would be subjected to corrosive contaminants since the environment is dry and inerted. They are static devices designed for thermal expansion between the drywell and torus during a DBA, therefore they do not experience inservice stresses that would make them susceptible to SCC. The leak rate testing (ref. ST-39B-X201) performed to date provides reasonable assurance that the structural integrity of these expansion bellows remains intact. | |||

maintenance rule baseline (initial) inspections were performed in 1997 and future monitoring inspection frequencies were established based on the results of the baseline inspections. In cases where random cracks were identified in either reinforced concrete or masonry, a shorter monitoring interval of 2 years was established to confirm the condition was not a degrading condition (i.e., shrinkage cracks). For the majority of cases, the 2-year frequency has been continued until the present. As a result, the multiple inspections of these structures have confirmed the condition is not progressing and will not affect functional capabilities. No additional inspections are required during the next planned inspection for any items that have cracks identified. | |||
As discussed in the Item #199 response, the only cracks of any significance that were reported during the 2005 inspection was associated with the RWCU Heat Exchanger concrete pedestal. | |||
However, there were a number of reinforced concrete and masonry items that were inspected in 2005 that contain hairline cracks that were reported during previous inspections and continue to be monitored. Any hairline cracks that are identified and being monitored in reinforced concrete are reviewed by experienced structural engineers to confirm they are not associated with a structural loading condition. Likewise, most hairline cracks being monitored in masonry construction are located in joint lines and are attributed to shrinkage. Minor pre-existing masonry wall hairline crack in the block face in the Electric Bay (Inspection # 05-TB-272-002-03) and in the West Diesel Fire Pump Room (Inspection # 05-SW-255-006-03) are being monitored on 2-year frequencies. | |||

In the qualifying evaluation, the original flaw is assumed to grow to 360 degrees circumferentially and 100% through wall. No credit is taken for the original pipe wall thickness. In addition, the weld metal used is resistant to IGSCC as discussed in BWRVIP-75-A and the specific NRC SER's. Future acceptability of the weld overlay is assured through inspections required by the ISI program and BWRVIP-75-A. There are no TLAA associated with these weld overlays. | |||
There are no welds that are monitored for crack growth under the ISI Program and / or BWRVIP A. All welds that were determined to contain cracking were repaired by weld overlay. | |||
Shroud Cracking JAFNPP performed baseline inspection of the shroud per BWRVIP-76 guidelines during the RO12 and RO13 refueling outages. Calculation JAF-CALC-NBS-04298 determined the inspection intervals to be used for monitoring the noted crack indications. Calculation JAF-CALC-NBS-04298 is not a TLAA since its time-limited assumptions are based on inspection intervals, not the current 40 year operating term. Subsequently, shroud tie-rods were installed to carry the load previously borne by the cracked welds. | |||
Steam Dryer Calculations associated with crack indications on the steam dryer are not TLAA since the associated 90 | |||

calculations justify the time interval between periodic inspections, not the acceptability for the current 40-year operating term. | |||
Core Spray Piping Calculations associated with crack indications on the core spray piping are not TLAA since these calculations justify the time interval between inspections and do not justify operation for the current 40-year operating term. These crack indications are monitored by the BWR vessel internals program per BWRVIP-18A guidelines. | |||
Main Steam Nozzle UT inspection performed as part of the JAFNPP ISI program revealed a subsurface indication on main steam nozzle N3C. There has been no discernable change in the size of the indication during subsequent inspections. This indication is believed to be a flaw remaining from vessel construction and will continue to be monitored by ISI. There is no associated calculation with a time-limited assumption and, therefore, no TLAA is associated with this indication. | |||
Torus Crack In June of 2005 a small through-wall crack was identified in the torus shell in the vicinity of the torus support between bays A and P. Failure analysis indicated that the crack was likely caused by fatigue due to condensation oscillation associated with operation of the HPCI exhaust discharge to the torus. This crack was repaired. In followup inspections, two additional cracks were found. These two cracks were also repaired. No analysis involving a time-limited assumption 91 | |||

defined by the current operating term is associated with the repairs, and therefore, there is no TLAA associated with these torus cracks. | |||
Residual Heat Removal (RHR) Shutdown Cooling Line Through-Wall Crack In July of 2005 a through-wall crack was discovered on the RHR shutdown cooling (SDC) system common suction piping. The cause of this crack was determined to be low stress, high cycle fatigue at the heat affected zone of the weld resulting from increased pipe movement during operation due to inadequate pipe engagement of an adjacent support (PFSK-2084) during original installation. This pipe and the associated support were repaired in accordance with code requirements.. An additional inspection in 2006 discovered two additional cracks which were also repaired. No analysis involving a time-limited assumption defined by the current operating term is associated with the repair, and therefore, there is no TLAA associated with this piping crack. | |||
No JAFNPP flaw growth analyses were identified that would qualify as TLAA (i.e., no other analyses were performed to qualify acceptability of flaws for the current operating term of the plant). | |||

Each of the staffs concerns with this approach is addressed below. | |||
I. That is correct, the plant-specific note used for the Table 2 AMR line-items does not provide a clear commitment as to how the One-Time Inspection program will be implemented to verify effectiveness of the water chemistry control programs. However, listing the One-Time Inspection Program in the Aging Management Program column of the table for each line item crediting a water chemistry control program also does not provide a clear commitment as to how the One-Time Inspection Program will be implemented. | |||
The commitment to implement the One-Time Inspection Program is contained in LRA Section B.1.21 and in LRA Appendix A. | |||

Engineering report JAF-RPT-05-LRD-02, Aging Management Program Evaluation Report, (AMPER) is available for onsite review. The description of this one-time inspection activity in Attachment 2 of the AMPER states that, A representative sample of components crediting water chemistry control programs for aging management will be inspected. However, due to a history of low oxygen and high iron (magnetite) content in the Reactor Building Closed Loop Cooling System, a specific sample of components in this system will be inspected. To implement this activity, the entire list of components crediting water chemistry control programs for aging management will have to be considered to determine the representative sample.

The stressors thermal cycling, ohmic heating, and electrical transients are potential stressors only for high load connections. | |||
Thermal cycling, ohmic heating, and electrical transients are not potential stressors for low load connections. Low-load connections located in a controlled environment can be screened out, because vibration, chemical contamination, corrosion and oxidation are not a concern. Low-load in-scope field instrumentation connections such as pressure transmitters, RTDs, and flow transmitters are not subject to AMR, because the in-scope instrumentation located in a harsh environment, are typically EQ, and the non-EQ sensitive instrument circuit (high radiation and neutron monitoring) connections which are included in the XI.E2 program. All connections associated with circuits that do not have an intended function, such as general lighting, are not subject to AMR. | |||
Methods To Identify Cable Connections The methods used to identify cable connections to include in the AMP were based on discussions in the November 30, 2006 NEI meeting with the NRC. | |||
The types of circuits considered for identifying cable connections were electrical and I&C penetrations, DC load centers, inverters, battery chargers, motors, MCCs, switchgear, circuit breakers, transformers, metal-enclosed bus, and field components. All of the electrical and I&C penetrations are EQ; therefore, all of the 120 | |||
Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant Applicant's No. Audit Questions Applicants Response Project Team's Evaluations Ref. No. | |||
connections for these penetrations were excluded. | |||
The field components considered includes current / | |||
potential transformers (CTs/PTs), and power supplies. The assumption made for the non-EQ high load connections was that all of these connections are bolted. | |||
The basis discusses the stressors that are being addressed. Plant information (single line drawings, switchyard drawings) was searched to determine the potential population of bolted connections. The criterion used for determining the high load connections was identifying power circuits for all voltage levels. The types of cable connections that were determined to meet the definition of a high load connection are subject to AMR. In addition to the one-time inspection program, many of the JAFNPP cable connections are inspected or tested by PMs. The maintenance procedures (PMs) for the following components were searched to determine if the PM evaluated the field cable connections associated with the active components. | |||

For environmental conditions at JAFNPP, no significant aging has been identified that could cause a loss of intended function for the period of extended operation.

bounded by the types that are included. There is a set percentage of composite conductor strength established at which a transmission conductor is replaced. As illustrated below, there is ample strength margin to maintain the transmission conductor intended function through the period of extended operation. | |||
The National Electrical Safety Code (NESC) requires that tension on installed conductors be a maximum of 60% of the ultimate conductor strength. The NESC also sets the maximum tension a conductor must be designed to withstand under heavy load requirements, which includes consideration of ice, wind and temperature. These requirements are reviewed concerning the specific conductors included in the AMR. The conductors with the smallest ultimate strength margin (4/0 ACSR) will be used as an illustration. | |||
The ultimate strength and the NESC heavy load tension requirements of 4/0 (212 MCM) ACSR are 8350 lbs. and 2761 lbs. respectively. The margin between the NESC Heavy Load and the ultimate strength is 5589 lb.; i.e., there is a 67% of ultimate strength margin. The Ontario Hydroelectric study showed a 30% loss of composite conductor strength in an 80 year old conductor. In the case of the 4/0 ACSR transmission conductors, a 30% loss of ultimate strength would mean that there would still be a 37% ultimate strength margin between what is required by the NESC and the actual conductor strength. The 4/0 ACSR conductors have the lowest initial design margin of transmission conductors included in the AMR. | |||
This illustrates with reasonable assurance that transmission conductors will have ample strength through the period of extended operation. | |||

There are no applicable aging effects that could cause loss of the intended function of the transmission conductors for the period of extended operation. | |||
A review of industry OE and NRC generic communications related to the aging of transmission conductors ensured that no additional aging effects exist beyond those previously identified. A review of plant-specific OE did not identify any unique aging effects for transmission conductors. | |||

significant aging. The in-scope transmission conductors at JAFNPP are limited to the connections from the 115 kV switchyard to the station service transformer for the SBO recovery path. JAFNPP performs infrared inspection of the 115 kV switchyard connections as part of a PM task that is performed at least once each year.. This PM and the absence of plant OE confirms that no significant aging is occurring for JAFNPP. Based on this information, torque relaxation of transmission connections does not require aging management for JAFNPP. | |||
Loss of material due to corrosion of connections due to surface oxidation is an applicable aging mechanism, but is not significant enough to cause a loss of intended function. The components in the switchyard are exposed to precipitation, but these components do not experience any appreciable aging effects in this environment, except for minor oxidation, which does not impact the ability of the connections to perform their intended function. At JAFNPS, switchyard connection surfaces are coated with an anti-oxidant compound (i.e., a grease-type sealant) prior to tightening the connection to prevent the formation of oxides on the metal surface and to prevent moisture from entering the connections thus reducing the chances of corrosion. Based on operating experience, the method of installation has been shown to provide a corrosion resistant low electrical resistance connection. In addition, the infrared inspection of the 115KV switchyard verifies that this aging effect is not significant for JAFNPP. | |||
Therefore, it is concluded that general corrosion resulting from oxidation of switchyard connection surface metals does not require management at JAFNPP. | Therefore, it is concluded that general corrosion resulting from oxidation of switchyard connection surface metals does not require management at JAFNPP. | ||

The review found instances of loss of material due to corrosion, loose bolting due to improper maintenance practices, and cracking of Class 1 bolting, but no evidence of cracking or loss of preload for non-Class 1 pressure boundary bolting. | |||
AMR line item 3.3.1-45 states not applicable in the discussion section that describes loss of preload due to thermal effects, gasket creep, and self-loosening.

Appendix A, Section A.1.2.2 states that risk significance may be considered in developing the details of an aging management program (see excerpt below). | |||
The risk significance of a structure or component could be considered in evaluating the robustness of an aging management program. Probabilistic arguments may be used to assist in developing an approach for aging management adequacy. | |||
However, use of probabilistic arguments alone is not an acceptable basis for concluding that, for those structures and components subject to an AMR, the effects of aging will be adequately managed in the period of extended operation. | |||
Thus, risk significance may be considered in developing the details of an aging management program for the structure or component for license renewal, but may not be used to conclude that no aging management program is necessary for license renewal. Therefore, periodic inspections of non-safety related systems conducted on a five year frequency or less is acceptable. | |||

Any significant loss of material detected will be evaluated to determine if corrective actions, including expansion of the inspection sample size, are required. The project team finds these activities acceptable to manage loss of material for these components since, based on industry research and operating experience, this material/environment combination is not susceptible to corrosion. In addition, the components exposed to drains are not continuously wetted, which further reduces their susceptibility to corrosion.

System for plant startup, operating and shutdown required. This question is resolved. | |||
This | power including adequate power to the emergency service buses for the safe shutdown of the reactor. | ||
The 115KV bus at JAF is energized from two 115KV transmission lines as shown in SAR Figure 8.3-2. This provides the GDC- 17 criteria for the Reserve Service Station Transformers. Section 8.11 of the JAF UFSAR, addresses Station Blackout (SBO). Station Blackout (SBO) is defined in 10 CFR 50.2 as a complete loss of alternating current (AC) electric power to essential and non-essential switchgear buses. Offsite power is assumed to be lost concurrently with a main turbine trip and unavailability of the on-site emergency AC power system. Station Blackout does not include loss of AC power to buses fed by the station batteries through inverters and does not assume a concurrent single failure or design basis accident. | |||
Section 8.2.1 of the JAF UFSAR, states that An alternate source of AC power, from the 345KV system, is available to provide power to plant auxiliaries during plant shutdown. The power is supplied to plant 4.16KV buses by back feeding from the 345KV system via main transformers, isolated phase bus duct, and the normal station service transformer. The main generator is isolated by removing the isolated phase bus duct disconnect links. This alternate source is only used during outages for maintenance on the Reserve Service Station Transformer. This source of offsite AC power is not credited for recovery from Station Blackout. | |||
The two sources of offsite AC power is the two independent 115KV lines that feed the RSST transformers. There is a cross feed circuit that can be closed to provide power to both of the 4.16KV safety buses in the plant in the case of loss of one 115KV line. This cross-tie can be closed in less than ten minutes when needed. This source will be much faster than installing the feedback source which takes at least [[estimated NRC review hours::12 hours]]. No other source is needed or required. | |||

The vertical seismic Load Factor of 0.2 gs is in the original design parameters as shown in Attachment 1, pg 3. However, transient conditions stated on page 4 does not include seismic loading. This is due to the fact that the low vertical seismic is compensated by dead weight, resulting in zero tensile stress in the reactor vessel studs. | |||

The fire pump diesel fuel oil tanks and the EDG day tanks are not currently subjected to internal inspections. An inspection frequency cannot be firmly established until the internal condition of these tanks is baselined. JAFNPP therefore plans to inspect these tanks on an eight year frequency similar to the EDG underground storage tanks. This frequency is based on the past inspection results of the EDG underground fuel oil storage tanks which have not indicated significant degradation while exposed to the same internal fuel oil environment.
If initial inspections find unexpected conditions the frequency will be adjusted via the corrective action process.

The discussion of water chemistry effects on fuel integrity includes information on recent fuel failures. The committee reduced the Action Level 1 limit for feedwater copper from 0.5 to 0.2 ppb, and added diagnostic parameters for feedwater and reactor water iron.
Recent plant data on the effect of oxygen on flow accelerated corrosion (FAC) resulted in the committee raising the Action Level 1 limit for dissolved oxygen in the feedwater from a minimum of 15ppb to 30ppb. The recommendations for water chemistry control and diagnostic parameters in Section 4 now include separate tables for normal water chemistry and hydrogen water chemistry (including NMCA). It is possible to relax the limits for chloride and sulfate in the HWC cases. The 30

Section 3 covers radiation field effects of water chemistry. The guidelines update the discussion of the effects of NMCA and zinc injection on radiation fields with the most recent plant data, and strengthen the discussion on control of feedwater iron with the recognition that iron increases fuel crud formation and decreases the efficiency of zinc.
Section 4 covers Flow Accelerated Corrosion (FAC) and now includes the effects of NMCA.
Section 5 discusses water chemistry impacts on fuel integrity, including corrosion-related fuel failures and the need for control of feedwater zinc, iron and copper. The guidelines recommend quarterly average maxima for feedwater zinc of 0.6 ppb for HWC plants and 0.4 ppb for NMCA plants based on fuel integrity issues.
Section 6 comprises the recommendations for water chemistry control and diagnostic parameters, which now include separate tables for hydrogen water chemistry, HWC/NMCA and normal water chemistry.

Section 7 is a new section containing recommended goals for water chemistry optimization. These are good practice recommendations for targets that plants may use in optimizing water chemistry to balance the conflicting requirements of materials, fuel and radiation control.
Section 8 discusses recommended chemistry surveillance. The guidelines reduce recommended surveillance and monitoring frequencies in order to reduce O&M costs, as long as there is no significant adverse impact on plant chemistry.
Appendices discuss the effects of impurity transients on crack growth rates, auxiliary systems, conductivity corrections for the presence of ionic species that are benign toward system integrity, ultrasonic fuel cleaning and the BWRVIP radiolysis model.
This document, which replaces the 2000 revision (BWRVIP-79), provides proactive water chemistry recommendations for BWRs during all modes of operation. It summarizes the technical bases for all water chemistry alternatives and provides guidance on the development of plant-specific chemistry programs.

There were two less prevalent issues identified in 2000 assessment. The Surveillance Test Program and the Corrective Action Program (CAP) were issues that resulted in effectiveness reviews being conducted for both programs. Corrective actions were initiated to correct and improve both programs. Several ESW Condition Reports issued prior to 2000 required adjustments in significant level and closure of corrective actions. All issues identified regarding the CAP have been addressed.
Additionally, all issues associated with the Surveillance Test Program have been addressed and included in the creation of a Surveillance Program Coordinator and a Surveillance Program Round Table.
Several NRC inspections confirm that the strength of the significant improvements made within the ESW system. Integrated Inspection Report 05000333/2003008 is one example. During the ESW and support systems review, the ESW system was heavily scrutinized. The inspection reviewed open work requests, temp mods, and operator workarounds to assess the collective impact on system operation. The inspection reviewed the condition report database to verify that equipment alignment problems were being identified and appropriately resolved. No findings of 45

Again, no findings of significance were identified.
Inspectors witnessed surveillance testing of service water systems and reviewed test data to assess whether the SSCs satisfied TS, UFSAR, Technical Requirements Manual, and Entergy procedural requirements. Again, no findings of significance were identified. Inspectors performed a detailed review of 69 corrective action program items assessing Entergy's threshold for problem identification, adequacy of cause analysis and extent of condition reviews, and timeliness of the corrective actions required. No findings of significance were identified.
Problem Identification and Resolution Inspection Report 05000333/2004006 is another example of the significant improvements made within the ESW system. The identification and resolution of problems was reviewed by the NRC. Their inspection team reviewed all aspects of the corrective action program (CAP). No findings of significance were identified. There were minor deficiencies noted. The team concluded that the plant staff identified deficiencies and entered them in the CAP, and at the appropriate threshold. The team also found that the self assessments and audits were sufficiently self-critical and provided relevant performance observations and insights.
The team found that with regard to prioritization and evaluation of issues including service water system erosion and/or corrosion, heat exchanger fouling that there were no findings of significance identified. There were some minor instances of documentation issues.

The results of each subsequent monitoring inspection are recorded and evaluated to establish the time for the next inspection. The interval before the next inspection for a structure may decrease, increase, or remain the same based on the condition of the structure relative to the previous inspection. A Condition Report (CR) is issued for any structures that require immediate attention or a Work Order is initiated for minor degradation that requires attention. Inspection Checklist data sheets from the most recent inspections are available for review.
The following reinforced concrete and masonry degradations, including cracks and gaps, were reported during the 2005 SMP inspections:
The SMP inspection of the RWCU Heat Exchanger (Inspection # 05-RB-300-005-03) reinforced concrete pedestal foundation monitors a degraded concrete condition. The steel frame supporting each end of the three stacked RWCU heat exchangers rests on concrete pedestals. One of the concrete pedestals had degraded by the loss of concrete from top and side surfaces located adjacent to the bearing surface of the steel frame.
Past repairs were not effective in restoring the concrete due to the thermal expansion of the heat exchangers.
The most recent inspection in 2005 confirmed there was no change in the concrete condition from the previous inspection in 2003 (i.e., 2-year frequency).
The broken concrete condition exceeds the acceptance criteria of hairline cracks and therefore 72
Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant Applicant's No. Audit Questions Applicants Response Project Team's Evaluations Ref. No.
condition reports have been written to provide immediate management attention. As a result, an engineering change package has been designed and issued to restore the support structure and is scheduled for implementation. The monitoring frequency will remain at 2-years for this item.
The SMP inspection of the Emergency Diesel Generator Room (Inspection # 05-ED-272-002-03,
- 05-ED-272-004-03) of masonry block walls identified separations between the reinforced concrete wall and the end of the adjoining masonry walls. The vertical joint between the walls has separated from the joint filler such that a small (cracklike) opening has formed at several locations along the joint. The joint filler serves to fill the gap between the two walls and does not contribute to the structural integrity of the walls Therefore, a work order has been issued to repair the filler material. The repair work has not been scheduled.
The monitoring frequency will remain at 2-years for these items.
No corrosion was reported during the 2005 inspections for reinforced concrete and masonry items.

From 1990 to 2003 Dresden/Quad Cities replaced or removed the degraded bellows from service. The SER states that several of the 73

replaced bellows received metallurgical analysis.
Analysis results from a couple of examples determined the presence of corrosive products, such as magnesium salts, chlorides, fluorides, and sulfides. Also, these corrosive species are not typical of containment operating conditions. As a result, the SER concludes the corrosive species, leading to the site specific degradation of the bellows, were most probably introduced during plant construction. (Reference Dresden/Quad Cities SER pages 3-403 to 3-408)
Cracking due to SCC for the JAFNPP containment bellows is not an aging affect requiring management. There is no JAFNPP site-specific operating experience similar to that of Dresden/Quad Cities. In summary, the presence of corrosive contaminants is necessary for SCC to occur. The normal environment for the JAFNPP drywell is dry and there has been no indication of contamination of the bellows during construction. In addition, containment bellows for JAFNPP are not exposed to a corrosive environment. As such, SCC is not applicable to JAFNPP stainless steel bellows. (Ref. LRA paragraph 3.5.2.2.1.7)
There is nothing to indicate that the bellows have been or would be subjected to corrosive contaminants since the environment is dry and inerted. They are static devices designed for thermal expansion between the drywell and torus during a DBA, therefore they do not experience inservice stresses that would make them susceptible to SCC. The leak rate testing (ref. ST-39B-X201) performed to date provides reasonable assurance that the structural integrity of these expansion bellows remains intact.

As a result, the multiple inspections of these structures have confirmed the condition is not progressing and will not affect functional capabilities. No additional inspections are required during the next planned inspection for any items that have cracks identified.
As discussed in the Item #199 response, the only cracks of any significance that were reported during the 2005 inspection was associated with the RWCU Heat Exchanger concrete pedestal.
However, there were a number of reinforced concrete and masonry items that were inspected in 2005 that contain hairline cracks that were reported during previous inspections and continue to be monitored. Any hairline cracks that are identified and being monitored in reinforced concrete are reviewed by experienced structural engineers to confirm they are not associated with a structural loading condition. Likewise, most hairline cracks being monitored in masonry construction are located in joint lines and are attributed to shrinkage. Minor pre-existing masonry wall hairline crack in the block face in the Electric Bay (Inspection # 05-TB-272-002-03) and in the West Diesel Fire Pump Room (Inspection # 05-SW-255-006-03) are being monitored on 2-year frequencies.
A work order has been issued to repair the West Diesel Fire Pump Room hairline crack.

management programs for water environments.
Water flowing is defined in NUREG-1801 as water that is refreshed, thus having larger impact on leaching; this can be rainwater, raw water, groundwater, or flowing water under a foundation.
For the purposes of the JAFNPP aging management review, water-flowing was considered flowing water at greater than 3 fps. (Ref. EPRI report 1002950 Aging Effects for Structures and Structural Components (Structural Tools), Section 3.3.1.4)
The potential aging effect resulting from flowing water is loss of material. For concrete, structures monitoring manages loss of material as identified in LRA Tables 3.5.2-1 through 3.5.2-4.

Therefore these and installed in accordance with Generic Letter 88- flaw evaluations do not meet the definition 01, NUREG-0313, Rev. 2, and ASME Code of a TLAA in 10 CFR 54.3. This question requirements and approved by the NRC via a SER. is resolved.
In the qualifying evaluation, the original flaw is assumed to grow to 360 degrees circumferentially and 100% through wall. No credit is taken for the original pipe wall thickness. In addition, the weld metal used is resistant to IGSCC as discussed in BWRVIP-75-A and the specific NRC SER's. Future acceptability of the weld overlay is assured through inspections required by the ISI program and BWRVIP-75-A. There are no TLAA associated with these weld overlays.
There are no welds that are monitored for crack growth under the ISI Program and / or BWRVIP A. All welds that were determined to contain cracking were repaired by weld overlay.
Shroud Cracking JAFNPP performed baseline inspection of the shroud per BWRVIP-76 guidelines during the RO12 and RO13 refueling outages. Calculation JAF-CALC-NBS-04298 determined the inspection intervals to be used for monitoring the noted crack indications. Calculation JAF-CALC-NBS-04298 is not a TLAA since its time-limited assumptions are based on inspection intervals, not the current 40 year operating term. Subsequently, shroud tie-rods were installed to carry the load previously borne by the cracked welds.
Steam Dryer Calculations associated with crack indications on the steam dryer are not TLAA since the associated 90

calculations justify the time interval between periodic inspections, not the acceptability for the current 40-year operating term.
Core Spray Piping Calculations associated with crack indications on the core spray piping are not TLAA since these calculations justify the time interval between inspections and do not justify operation for the current 40-year operating term. These crack indications are monitored by the BWR vessel internals program per BWRVIP-18A guidelines.
Main Steam Nozzle UT inspection performed as part of the JAFNPP ISI program revealed a subsurface indication on main steam nozzle N3C. There has been no discernable change in the size of the indication during subsequent inspections. This indication is believed to be a flaw remaining from vessel construction and will continue to be monitored by ISI. There is no associated calculation with a time-limited assumption and, therefore, no TLAA is associated with this indication.
Torus Crack In June of 2005 a small through-wall crack was identified in the torus shell in the vicinity of the torus support between bays A and P. Failure analysis indicated that the crack was likely caused by fatigue due to condensation oscillation associated with operation of the HPCI exhaust discharge to the torus. This crack was repaired. In followup inspections, two additional cracks were found. These two cracks were also repaired. No analysis involving a time-limited assumption 91

defined by the current operating term is associated with the repairs, and therefore, there is no TLAA associated with these torus cracks.
Residual Heat Removal (RHR) Shutdown Cooling Line Through-Wall Crack In July of 2005 a through-wall crack was discovered on the RHR shutdown cooling (SDC) system common suction piping. The cause of this crack was determined to be low stress, high cycle fatigue at the heat affected zone of the weld resulting from increased pipe movement during operation due to inadequate pipe engagement of an adjacent support (PFSK-2084) during original installation. This pipe and the associated support were repaired in accordance with code requirements.. An additional inspection in 2006 discovered two additional cracks which were also repaired. No analysis involving a time-limited assumption defined by the current operating term is associated with the repair, and therefore, there is no TLAA associated with this piping crack.
No JAFNPP flaw growth analyses were identified that would qualify as TLAA (i.e., no other analyses were performed to qualify acceptability of flaws for the current operating term of the plant).

Each of the staffs concerns with this approach is addressed below.
I. That is correct, the plant-specific note used for the Table 2 AMR line-items does not provide a clear commitment as to how the One-Time Inspection program will be implemented to verify effectiveness of the water chemistry control programs. However, listing the One-Time Inspection Program in the Aging Management Program column of the table for each line item crediting a water chemistry control program also does not provide a clear commitment as to how the One-Time Inspection Program will be implemented.
The commitment to implement the One-Time Inspection Program is contained in LRA Section B.1.21 and in LRA Appendix A.
II. As stated above, the plant-specific note is not intended to obfuscate use of the One-Time Inspection Program. It is intended to simplify the tables in Sections 3.1 through 3.4 of the LRA.
Since the plant specific note is applied to every line item crediting a water chemistry control program, it should be understood by the reader that effectiveness of the water chemistry control program associated with each line item is confirmed by the One-Time Inspection Program.
Including the One-Time Inspection Program in a note rather than in the Aging Management Program column of the tables does not minimize its importance. See response to iii, below.
III. The commitment to implement the One-Time Inspection Program is contained in LRA Section B.1.21 and in Appendix A. In accordance with NUREG-1801, XI.M32, with which the One-Time Inspection Program is consistent, the inspection includes a representative sample of the population, 108

and, where practical, focuses on the bounding or lead components most susceptible to aging due to time in service, severity of operating conditions, and lowest design margin. Engineering report JAF-RPT-05-LRD-02, Aging Management Program Evaluation Report, (AMPER) is available for onsite review. The description of this one-time inspection activity in Attachment 2 of the AMPER states that, A representative sample of components crediting water chemistry control programs for aging management will be inspected. However, due to a history of low oxygen and high iron (magnetite) content in the Reactor Building Closed Loop Cooling System, a specific sample of components in this system will be inspected. To implement this activity, the entire list of components crediting water chemistry control programs for aging management will have to be considered to determine the representative sample. Therefore, the One-Time Inspection Program cannot be overlooked even though it is not listed in the Aging Management Program column of the Table 2 AMR line-items.

As discussed during the November 30, the ten elements for cable connections. 2006 meeting and during the JAF AMR audit, that bolted connections are the main concern.
The stressors thermal cycling, ohmic heating, and electrical transients are potential stressors only for high load connections.
Thermal cycling, ohmic heating, and electrical transients are not potential stressors for low load connections. Low-load connections located in a controlled environment can be screened out, because vibration, chemical contamination, corrosion and oxidation are not a concern. Low-load in-scope field instrumentation connections such as pressure transmitters, RTDs, and flow transmitters are not subject to AMR, because the in-scope instrumentation located in a harsh environment, are typically EQ, and the non-EQ sensitive instrument circuit (high radiation and neutron monitoring) connections which are included in the XI.E2 program. All connections associated with circuits that do not have an intended function, such as general lighting, are not subject to AMR.
Methods To Identify Cable Connections The methods used to identify cable connections to include in the AMP were based on discussions in the November 30, 2006 NEI meeting with the NRC.
The types of circuits considered for identifying cable connections were electrical and I&C penetrations, DC load centers, inverters, battery chargers, motors, MCCs, switchgear, circuit breakers, transformers, metal-enclosed bus, and field components. All of the electrical and I&C penetrations are EQ; therefore, all of the 120
Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant Applicant's No. Audit Questions Applicants Response Project Team's Evaluations Ref. No.
connections for these penetrations were excluded.
The field components considered includes current /
potential transformers (CTs/PTs), and power supplies. The assumption made for the non-EQ high load connections was that all of these connections are bolted.
The basis discusses the stressors that are being addressed. Plant information (single line drawings, switchyard drawings) was searched to determine the potential population of bolted connections. The criterion used for determining the high load connections was identifying power circuits for all voltage levels. The types of cable connections that were determined to meet the definition of a high load connection are subject to AMR. In addition to the one-time inspection program, many of the JAFNPP cable connections are inspected or tested by PMs. The maintenance procedures (PMs) for the following components were searched to determine if the PM evaluated the field cable connections associated with the active components.
- 480 VAC MCCs and Switchgear (MP-056.01 AC Motor Control Center Maintenance)* 600 VAC MCCs and Switchgear (MP-056.01 AC Motor Control Center Maintenance)* 4160 VAC Switchgear (MP-054.02 4.16kV Bus and Metal-Clad Switchgear)* AC Motors (MP-059.83 Motor Power Monitoring (MPM) Testing and Analysis) DC Motors (MP-059.83 Motor Power Monitoring (MPM)

- 125 VDC MCCs (MP.200.16 Maintenance and Subcomponent Replacement of GE 7700 Series DC Motor Control Centers)
- Battery Chargers
- Reserve Transformers (MP-071.42 Station Service Transformer Maintenance)
The maintenance procedures for these component types have details to detect degradation of bolted connections.
The maintenance rule indicators for the systems that contain these commodities do not show problems or issues that have not been resolved.
There is no plant OE that identified degraded connections where the degradation was a result of aging.
Conclusion JAFNPP will have a one-time inspection program that will inspect or test a representative sample of the connection types. The one-time inspection program will verify that there are no aging effects that require management during the period of extended operation. The program will have the following information.
Scope of Program Non-EQ connections associated with cables in scope of license renewal are included in this program. This program does not include the higher voltage (>35KV) switchyard connections. The inscope connections are screened for applicability of this program.
Parameters Monitored/Inspected This program will focus on the metallic parts of the cable connections. The one-time inspection verifies 122
Question and Answer Database Audit and Review Related to the License Renewal Application for James A. Fitzpatrick Nuclear Power plant Applicant's No. Audit Questions Applicants Response Project Team's Evaluations Ref. No.
that the loosening of bolted connections due to thermal cycling, ohmic heating, electrical transients, vibration, chemical contamination, corrosion, and oxidation do not require a periodic aging management program. A representative sample of the electrical cable connection population subject to aging management review will be inspected and tested. The sample will include each type of electrical cable connection. The following factors will be considered for sampling:

conductor bolted connections are assembled similar to the transmission conductor bolted connections discussed in question 299. For environmental conditions at JAFNPP, no significant aging has been identified that could cause a loss of intended function for the period of extended operation. Vibration is not applicable since flexible connectors connect switchyard bus to active components.
Although not specifically stated, the switchyard connections requiring AMR are welded and bolted connections. Neither of these connection types require aging management, because the loosening of bolted connections is not a significant aging effect.
This requires an LRA amendment.

bounded by the types that are included. There is a set percentage of composite conductor strength established at which a transmission conductor is replaced. As illustrated below, there is ample strength margin to maintain the transmission conductor intended function through the period of extended operation.
The National Electrical Safety Code (NESC) requires that tension on installed conductors be a maximum of 60% of the ultimate conductor strength. The NESC also sets the maximum tension a conductor must be designed to withstand under heavy load requirements, which includes consideration of ice, wind and temperature. These requirements are reviewed concerning the specific conductors included in the AMR. The conductors with the smallest ultimate strength margin (4/0 ACSR) will be used as an illustration.
The ultimate strength and the NESC heavy load tension requirements of 4/0 (212 MCM) ACSR are 8350 lbs. and 2761 lbs. respectively. The margin between the NESC Heavy Load and the ultimate strength is 5589 lb.; i.e., there is a 67% of ultimate strength margin. The Ontario Hydroelectric study showed a 30% loss of composite conductor strength in an 80 year old conductor. In the case of the 4/0 ACSR transmission conductors, a 30% loss of ultimate strength would mean that there would still be a 37% ultimate strength margin between what is required by the NESC and the actual conductor strength. The 4/0 ACSR conductors have the lowest initial design margin of transmission conductors included in the AMR.
This illustrates with reasonable assurance that transmission conductors will have ample strength through the period of extended operation.

There are no applicable aging effects that could cause loss of the intended function of the transmission conductors for the period of extended operation.
A review of industry OE and NRC generic communications related to the aging of transmission conductors ensured that no additional aging effects exist beyond those previously identified. A review of plant-specific OE did not identify any unique aging effects for transmission conductors.
Numerous previous applicants (Oconee, Turkey Point, North Anna and Surry, Peach Bottom, St.

significant aging. The in-scope transmission conductors at JAFNPP are limited to the connections from the 115 kV switchyard to the station service transformer for the SBO recovery path. JAFNPP performs infrared inspection of the 115 kV switchyard connections as part of a PM task that is performed at least once each year.. This PM and the absence of plant OE confirms that no significant aging is occurring for JAFNPP. Based on this information, torque relaxation of transmission connections does not require aging management for JAFNPP.
Loss of material due to corrosion of connections due to surface oxidation is an applicable aging mechanism, but is not significant enough to cause a loss of intended function. The components in the switchyard are exposed to precipitation, but these components do not experience any appreciable aging effects in this environment, except for minor oxidation, which does not impact the ability of the connections to perform their intended function. At JAFNPS, switchyard connection surfaces are coated with an anti-oxidant compound (i.e., a grease-type sealant) prior to tightening the connection to prevent the formation of oxides on the metal surface and to prevent moisture from entering the connections thus reducing the chances of corrosion. Based on operating experience, the method of installation has been shown to provide a corrosion resistant low electrical resistance connection. In addition, the infrared inspection of the 115KV switchyard verifies that this aging effect is not significant for JAFNPP.
Therefore, it is concluded that general corrosion resulting from oxidation of switchyard connection surface metals does not require management at JAFNPP.

Piping for James A. Fitzpatrick Nuclear Power Station, Revision 1, November, 1984 (page 13) states that 7500 cycles are allowed for the SRV discharge line penetration into the torus. The estimated total number of SRV actuations for 60 years is less than the number of actuations assumed in the design fatigue analysis. The estimate is based on actual SRV actuations counted thru November 4, 2006. The design fatigue analysis remains valid. Based upon this, the projected CUF for 60 years is calculated as 0.141.

Unique Analysis Report of the Torus Attached Piping Teledyne Engineering Services document TR-5321-2 documents stress evaluations for the SRV piping for various load combinations, but does not include a fatigue analysis. The fatigue analysis of the SRV piping along with all the other torus attached piping. (TAP) is bounded by Mark 1 Upgrades generic report MPR-751, prepared by GE. MPR-751 concluded that for all plants and piping systems considered, in all cases the fatigue usage factors for an assumed 40-year plant life was less than 0.5. In a worst-case scenario, extending plant life for an additional 20 years would produce usage factors below 0.75. Since this is less than 1.0, the fatigue criteria are satisfied. The MPR-751 generic fatigue analysis is thus protected for the period of extended operation in accordance with 10 CFR 54.21(c)(1)(ii)
A JAF plant specific analysis addresses the SRV discharge piping and its supports, as well as the main vent penetration through which the SRV discharge enters the torus. This analysis states that the SRV penetrations are qualified for 7500 cycles of maximum load while the SRVs are expected to see less than 50 cycles at maximum load and less than 4500 cycles at partial load. The TR-5321-2 report concludes "Since the 7500 cycles of maximum load bounds both of these by such a large margin and since no other significant loads are imposed on the line, the penetration was assumed acceptable for fatigue without further evaluation." Increasing the 40 year cycles by 1.5 for the period of extended operation would still be only 75 maximum load cycles and 6750 low load cycles for a total of 6850 mixed load cycles, less than the 7500 maximum load cycles permitted. The fatigue analysis for torus penetrations thus remains valid for the period of extended operation in 138

accordance with 10 CFR 54.21(c)(1)(I).
The JAF plant-specific analysis (TR-5321-2) references the generic GE Mark 1 Containment program for other torus attached piping. The results of the generic GE Mark 1 containment program (based on 40 years of operation) were that 92% of the TAP would have cumulative usage factors of less than 0.3, and that 100% would have usage factors less than 0.5. Conservatively multiplying the CUFs by 1.5 shows that for 60 years of operation, 92% of the TAP would have CUFs below 0.45, and 100% would have CUFs below 0.75. These calculations have thus been projected through the period of extended operation in accordance with 10 CFR 50.21(c)(ii).

Appendix A, Section A.1.2.2 states that risk significance may be considered in developing the details of an aging management program (see excerpt below).
The risk significance of a structure or component could be considered in evaluating the robustness of an aging management program. Probabilistic arguments may be used to assist in developing an approach for aging management adequacy.
However, use of probabilistic arguments alone is not an acceptable basis for concluding that, for those structures and components subject to an AMR, the effects of aging will be adequately managed in the period of extended operation.
Thus, risk significance may be considered in developing the details of an aging management program for the structure or component for license renewal, but may not be used to conclude that no aging management program is necessary for license renewal. Therefore, periodic inspections of non-safety related systems conducted on a five year frequency or less is acceptable.

The inspections will be performed during the 10-year period immediately prior to entering the period of extended operation to confirm that no significant aging degradation is occurring in these components. Any significant loss of material detected will be evaluated to determine if corrective actions, including expansion of the inspection sample size, are required. The project team finds these activities acceptable to manage loss of material for these components since, based on industry research and operating experience, this material/environment combination is not susceptible to corrosion. In addition, the components exposed to drains are not continuously wetted, which further reduces their susceptibility to corrosion. On this basis, the project team finds that AMR results addressed by this line item that credit the One-Time Inspection Program are acceptable.

Design Calculation EAS-149-1286 / DRF B13-01391 discusses GEs evaluation of 12 transients (i.e., nine reactor SCRAMS, one turbine trip, two feedwater pump trips) that had been grouped into the Shutdown transient for the plant. The report stated that the change in reactor coolant temperature (T) for six of these events had exceeded the T value for this transient. The staff noted that the bases provided on page 19 for justifying why these events can be categorized as plant heatups or cooldowns are based on qualitative analysis without using any temperature gradient data.
Justify why these six transients can be grouped intoShutdown transient for the plant when the T values for these six events were determined to excessive and the temperature gradients for the transients are not defined.
In particular, for the scram event that occurred on November 4, 1984, a T of -297 F and a T of +437 F occurred on the same day. Please define when did T events occur and what were the actual temperature gradients associated with these events.

power including adequate power to the emergency service buses for the safe shutdown of the reactor.
The 115KV bus at JAF is energized from two 115KV transmission lines as shown in SAR Figure 8.3-2. This provides the GDC- 17 criteria for the Reserve Service Station Transformers. Section 8.11 of the JAF UFSAR, addresses Station Blackout (SBO). Station Blackout (SBO) is defined in 10 CFR 50.2 as a complete loss of alternating current (AC) electric power to essential and non-essential switchgear buses. Offsite power is assumed to be lost concurrently with a main turbine trip and unavailability of the on-site emergency AC power system. Station Blackout does not include loss of AC power to buses fed by the station batteries through inverters and does not assume a concurrent single failure or design basis accident.
Section 8.2.1 of the JAF UFSAR, states that An alternate source of AC power, from the 345KV system, is available to provide power to plant auxiliaries during plant shutdown. The power is supplied to plant 4.16KV buses by back feeding from the 345KV system via main transformers, isolated phase bus duct, and the normal station service transformer. The main generator is isolated by removing the isolated phase bus duct disconnect links. This alternate source is only used during outages for maintenance on the Reserve Service Station Transformer. This source of offsite AC power is not credited for recovery from Station Blackout.
The two sources of offsite AC power is the two independent 115KV lines that feed the RSST transformers. There is a cross feed circuit that can be closed to provide power to both of the 4.16KV safety buses in the plant in the case of loss of one 115KV line. This cross-tie can be closed in less than ten minutes when needed. This source will be much faster than installing the feedback source which takes at least 12 hours0.5 days <br />0.0714 weeks <br />0.0164 months <br />. No other source is needed or required.

B. Paragraph N-416.2 b(1) requires that the peak stresses be calculated using a stress intensification factor of 4.0 (specified in paragraph N-416.4).
Original design calculation page A-107 shows that a stress concentration factor of 4.0 was used to calculate peak stresses.
C. Paragraph N-416.2 b(2) states that Salt is equal to one-half of the stress range (max peak stress minus min peak stress). Original design calculation page A-115 shows that Salt were calculated using this method required by the code.
ASME code in section N-416 does not require an additional correction factor to Salt (the Ke factor stated above). The peak alternating stresses already contain a factor of 4.0 due to stress concentration. Since the stresses in calculation EAS-149-1286 (DRF B13-01391) [Ref 3] were obtained from the original vessel calculations [Ref 1], then the methodology used in the original calculations apply to this calculation also.

- c. Shroud Tie Rod - Analysis of record and any margin calculations (list - with discussion).
The analysis of record for the shroud tie rod fatigue usage factors is:
1.Original MPR design calculation 291-9401-202, Tie Rod Assembly Stress Evaluation, Rev. 1, 10/21/1994. This calculates the maximum CUF as 0.0575 for 40-year operation. This CUF was multiplied by a ratio to obtain the 60-year operation CUF.
- 2. There are no margin calculations on shroud tie rod fatigue evaluation.
- d. Jet Pump Fatigue Evaluation
- 1. The CUF for the jet pump diffuser adapter was obtained from the UFSAR (pg 16.2-7) maximum value of 0.65 multiplied by a factor of 1.5. The UFSAR states that the fatigue analysis method is described in GE document APED-5460 Design and Performance of GE-BWR Jet Pumps, dated 220

- 2. From the 1987 GE Analysis - (EAS-149-1286/DRF B13-01391) provide the following input:
A. Justify the Operating Data Reduction as discussed in Table 2, 3. Actual plant data is listed in Table 2 from initial start-up through 7/3/1986.These events are summarized in Table
- 3. Based on these actual plant transients, projections were made for 40-year operation.
The actual plant data included the following:
- a. Summary of events from operator logs
- b. Post trip computer edits if available
- c. Recirculation temperature and flow rate strip charts.
- d. Feedwater and main steam flow rate strip charts.
- e. Reactor Pressure strip charts.
- f. Balance of plant logs
- g. Closure region tensioning data.
B. Provide justification on page 19 of the 6 transients that exceeded the original design basis.
These events are considered to be less severe than the original design basis events based on the following reasoning:
- 1) The Ts occur over a finite period of time, i.e.
they are not instantaneous.
- 2) Whenever data was available from balance of plant logs, it suggested that the temperature changes occurred relatively slowly, i.e. less than 100 o F/hour. Since it is a Technical Specifications requirement to shut down or startup the reactor less than or equal to 100 o F/hour this assumption was used when data was not available. This is conservative.
- 3) The original analysis (CE analysis) thermal stresses are inherently conservative because they are based on shell interaction equations and use conservative assumptions.
Thus, it is considered conservative to use the original design basis thermal stresses for the 221

updated fatigue evaluation.
3.Why seismic loading was not included in the RV head bolting fatigue analysis?
The vertical seismic Load Factor of 0.2 gs is in the original design parameters as shown in Attachment 1, pg 3. However, transient conditions stated on page 4 does not include seismic loading. This is due to the fact that the low vertical seismic is compensated by dead weight, resulting in zero tensile stress in the reactor vessel studs.
