4OA5 Review of License Renewal Activities (TI 2516/001) | |||
.1 Background | |||
The expiration date of the operating license for Indian Point Unit 2 is midnight on | |||
September 28, 2013. Indian Point Unit 2 meets the criteria in Title 10 of the Code of | |||
Federal Regulations (10 CFR) 2.109(b), Effect of timely renewal application, and will | |||
likely operate beyond the current operating license expiration date. Due to the | |||
Commissions decision to revise the Waste Confidence Decision and Rule and because | |||
of the ongoing Atomic Safety and Licensing Board hearings, the Commission is not | |||
expected to issue a renewed license for Indian Point Unit 2 before the expiration date of | |||
the original license. Therefore, Indian Point would continue operations under the timely | |||
renewal provisions of 10 CFR 2.109(b). | |||
The team used NRC Inspection Manual Temporary Instruction 2516/001 to conduct this | |||
inspection. The Temporary Instruction was written specifically for plants like Indian Point | |||
Unit 2, where the holders of an operating license meet the criteria of 10 CFR 2.109, for | |||
timely renewal, but a final decision by the NRC on the license renewal application is not | |||
expected prior to the period of extended operation. The inspection objectives and | |||
requirements of the Temporary Instruction are to report the status of license renewal | |||
commitment implementation, the status of aging management program implementation, | |||
and to verify the description of programs and activities for managing the effects of aging | |||
are consistent with the Updated Final Safety Analysis Report. | |||
The NRC has conducted three separate license renewal inspections that have reviewed | |||
a total of 44 license renewal commitments. Our first license renewal inspection | |||
conducted during a refueling outage, reviewed four commitments as documented in | |||
NRC Inspection Report 05000247/2012008 (ML12110A315). On May 23, 2013, the | |||
NRC completed a License Renewal Commitment Team Inspection, as documented in | |||
NRC Inspection Report 05000247/2013009 (ML13186A179). The team inspection | |||
concluded that Entergy had made sufficient progress to complete review of | |||
30 commitments and identified 11 commitments that merited further assessment during | |||
a planned follow-up inspection. During the current planned follow-up inspection, the | |||
inspectors completed our review of ten of the 11 commitments identified by the team as | |||
requiring additional review. Commitment 47, one of the 11 commitments previously | |||
identified for additional review, was not assessed during this inspection because Entergy | |||
revised the completion date for this commitment to March 1, 2015, in a letter to the NRC | |||
(ML13142A202). | |||
Enclosure | |||
2 | |||
.2 Commitment Reviews | |||
.2.1 Commitment 6: Enhance the Fatigue Monitoring Program to monitor steady state cycles | |||
and feedwater cycles or perform an evaluation to determine monitoring is not required. | |||
Review the number of allowed events and resolve discrepancies between reference | |||
documents and monitoring procedures. | |||
a. Inspection Scope | |||
In the prior inspection, the inspectors noted that Entergy had awarded contracts to | |||
perform calculations to determine whether monitoring of steady state cycles and | |||
feedwater cycles was required. The inspectors also noted that Entergy planned to | |||
revise procedure 2-PT-2Y015, Thermal Cycle Monitoring Program, if the calculations | |||
demonstrated that a change in the number of allowable steady state cycles and | |||
feedwater cycles was identified. | |||
During this inspection, the inspectors reviewed Westinghouse calculation IPP-13-20, | |||
Revision 1, dated August 14, 2013, reporting the Steady State Fluctuations and | |||
Feedwater Cycling Transient Disposition, presenting LTR-PAFM-13-87, Revision 2. | |||
This result determined that both transients do not significantly affect the fatigue of the | |||
primary system and can be removed from the transient cycle counting program. It was | |||
determined the feedwater cycle transient must still be tracked for the secondary side of | |||
the steam generator and feedwater piping, with a 25,000 cycle limit. The inspectors | |||
verified that procedure 2-PT-2Y015, Thermal Cycle Monitoring Program, Revision 4, | |||
tracked the feedwater cycle transients. | |||
Findings and Observations | |||
No findings were identified. | |||
.2.2 Commitment 13: Enhance the Metal-Enclosed Bus (MEB) Inspection Program to add a | |||
480 volt bus, visually inspect the external surface of MEB enclosure assemblies, include | |||
acceptance criteria, inspect bolted connections, and remove reference to re-torquing | |||
connections from the applicable site procedure. | |||
a. Inspection Scope | |||
In the prior inspection, the inspectors identified that Entergy had not included all | |||
accessible portions of the MEB within the scope of the maintenance inspection program. | |||
The inspectors noted that sections of the emergency diesel generator 480 volt MEB in | |||
the electrical tunnel had not been visually inspected and were not included in the scope | |||
of the maintenance procedure which performed the MEB inspections and tests. As a | |||
result of the NRCs observations, Entergy initiated a Condition Report | |||
(CR-IP2-2013-01786) to revise site procedures and conduct visual inspections of those | |||
additional sections of the bus ducts prior to the period of extended operations. | |||
During this inspection the inspectors reviewed the revised inspection and test | |||
procedures for the portions of the MEB previously considered to be inaccessible. The | |||
Enclosure | |||
3 | |||
inspectors reviewed the work orders under which the inspections and tests were | |||
completed for the three MEB sections and corrective action documents which resolved | |||
any identified conditions. | |||
Findings and Observations | |||
No findings were identified. | |||
.2.3 Commitment 19: Implement the One-Time Inspection Program as described in License | |||
Renewal Application, Section B.1.27. This new program will be implemented consistent | |||
with the corresponding program described in NUREG-1801, Section XIM32, One-Time | |||
Inspection. | |||
a. Inspection Scope | |||
In the prior inspection, the inspectors noted the One-Time Inspection Program involved | |||
over 400 inspections. Because Entergy had only completed approximately half of the | |||
planned inspections, the inspectors determined that additional NRC review was merited | |||
to assess the remaining inspection results; any further actions needed, and program | |||
conclusions. | |||
During this inspection the inspectors reviewed the One-Time Inspection Summary | |||
Report, the completed inspection tracking matrix, and 20 additional inspection reports. | |||
The inspectors determined that all inspection results were acceptable and there was no | |||
need for additional action. Further, Entergy concluded that the inspection results | |||
demonstrated that the existing aging management programs for water chemistry and the | |||
diesel fuel monitoring and oil analysis had been effective in managing aging. The test | |||
program results also indicated that additional inspections on components specified in the | |||
License Renewal Application had not identified any unacceptable degradation. | |||
Findings and Observations | |||
No findings were identified. | |||
.2.4 Commitment 23: Implement the Selective Leaching Program as described in License | |||
Renewal Application, Section B.1.33. This new program will be implemented consistent | |||
with the corresponding program described in NUREG-1801, Section XIM33 Selective | |||
Leaching of Materials. | |||
a. Inspection Scope | |||
In the prior inspection, the inspectors noted Entergy was in the progress of completing | |||
selective leaching inspections. The inspectors determined that additional NRC | |||
inspection was merited to review the results of the remaining inspections, any further | |||
actions needed, and program conclusions. | |||
During this inspection, the inspectors reviewed Selective Leaching Summary Report, | |||
including the final sampling plan, the destructive evaluation results of seven | |||
Enclosure | |||
4 | |||
components, and associated corrective action documents. Entergy determined that the | |||
visual inspections of 22 gray cast iron components and 17 copper alloy components | |||
showed an absence of selective leaching. However, destructive evaluations | |||
demonstrated that significant selective leaching (i.e., graphitization, had occurred in gray | |||
cast iron components) was occurring. While the commitment actions were complete, | |||
Entergy concluded that they would refine the process and documented a corrective | |||
action to perform engineering evaluations to develop a continuing monitoring program to | |||
manage and evaluate selective leaching. | |||
Findings and Observations | |||
No findings were identified | |||
.2.5 Commitment 26: Implement the Thermal Aging Embrittlement of Cast Austenitic | |||
Stainless Steel (CASS) Program as described in License Renewal Application, | |||
Section B.1.37. This new program will be implemented consistent with the | |||
corresponding program described in NUREG 1801, Section XI.M12, Thermal Aging | |||
Embrittlement of Cast Austenitic Stainless Steel Program. | |||
a. Inspection Scope | |||
In the prior inspection, the inspectors noted that Entergy was planning to screen all cast | |||
austenitic stainless steel components to determine which were potentially susceptible to | |||
a loss of fracture toughness. These components were to be further evaluated, using a | |||
refined analytical technique, to determine the components susceptibility to reduction in | |||
fracture toughness. Entergy chose to perform a unique fracture mechanics analysis of | |||
these components, which was in progress at the time of the prior inspection. The | |||
inspector noted that there may be a question regarding the submittal of the analysis | |||
under ASME requirements, as stipulated in 10 CFR 50.55a. | |||
Subsequently the inspector, in consultation with the Division of License Renewal, | |||
determined submittal of the analysis was not required. During this inspection the | |||
inspectors reviewed the completed evaluation of the screened components | |||
susceptibility to reduction in fracture toughness: Report 1300066.403, Revision 0, | |||
Aging Management of CASS Piping at Indian Point 2, Flaw Tolerance Evaluation of | |||
CASS Piping at Indian Point, dated August 2013. The methodology of probabilistic | |||
fracture mechanics determined a postulated starting reference flaw of one-quarter | |||
thickness would remain below the maximum allowable flaw size during a 60 year life for | |||
all components. | |||
Findings and Observations | |||
No findings were identified. | |||
.2.6 Commitment 27: Implement the Thermal Aging and Neutron Irradiation Embrittlement of | |||
Cast Austenitic Stainless Steel (CASS) Program as described in License Renewal | |||
Application, Section B.1.38. This new program will be implemented consistent with the | |||
Enclosure | |||
5 | |||
corresponding program described in NUREG-1801, Section XI.M13, Thermal Aging and | |||
Neutron Embrittlement of Cast Austenitic Stainless Steel program. | |||
a. Inspection Scope | |||
In the prior inspection, the inspectors noted a site document had not been developed | |||
that defined and implemented the screening criteria of Electric Power Research Institute | |||
(EPRI) Technical Report 1013234, Materials Reliability Program: Screening | |||
Categorization, and Ranking of Reactor Internals Components for Westinghouse and | |||
Combustion Engineering PWR Design, (MRP-191), listed in Table 3-5, as applied to the | |||
Indian Point components listed in Table 5-1 of EPRI Report 1022863, Materials | |||
Reliability Program: Pressurized Water Reactor Internals Inspection and Evaluation | |||
Guidelines, (MRP-227-A). | |||
During this inspection the inspectors reviewed Entergy Nuclear Engineering Report: | |||
Indian Point Energy Center: Thermal Aging and Neutron Irradiation Embrittlement of | |||
Cast Austenitic Stainless Steel Aging Management Program, IP-RPT-13-00049, | |||
Revision 0, dated August 14, 2013. This report implemented the above screening | |||
criteria and ranking methodology for Indian Point. | |||
Findings and Observations | |||
No findings were identified. | |||
.2.7 Commitment 33: For the locations identified in License Renewal Application, | |||
Table 4.3-13 (IP2), update the fatigue usage calculations using refined fatigue analyses | |||
to determine if Cumulative Usage Factors (CUF) remain less than 1.0 when accounting | |||
for the effects of reactor water environment, using valid Fen factors. | |||
a. Inspection Scope | |||
In the prior inspection, the inspectors noted that calculations documented in calculation | |||
WCAP 17149-P, Evaluation of Pressurizer Insurge/Outsurge Transients for Indian Point | |||
Unit 2, and WCAP 17199-P, Environmental Fatigue Evaluation for Indian Point Unit 2, | |||
concluded that cumulative fatigue usage factors, including reactor water environment | |||
effects, were below the American Society of Mechanical Engineers (ASME) Code | |||
allowable value of 1.0 for transients postulated for 60 years of operation. The inspectors | |||
noted Entergys action plan included revising the Thermal Cycle Monitoring Program | |||
procedure to reflect changes in the number of projected cycles used in WCAP 17199-P. | |||
During this inspection the inspectors reviewed Indian Point Programs and Components | |||
Engineering Procedure 2-PT-2Y015, Revision 4, Thermal Cycle Monitoring Program. | |||
The inspectors noted the procedure was updated to reflect the number of allowable | |||
cycles derived from the above analysis. The procedure referenced WCAP 17199-P and | |||
included a Table (Attachment 1) that included actual plant cycles rather than the number | |||
of cycles used in the original design calculations. The procedure also was revised to | |||
better reflect operational assumptions used and the bases for the revised calculations of | |||
the WCAP. | |||
Enclosure | |||
6 | |||
Findings and Observations | |||
No findings were identified. | |||
.2.8 Commitment 40: Evaluate plant specific and appropriate industry operating experience | |||
and incorporate lessons learned in establishing appropriate monitoring and inspection | |||
frequencies to assess aging effects for the new aging management programs. | |||
Documentation of the operating experience evaluated for each new program will be | |||
available on site for NRC review prior to the period of extended operation. | |||
a. Inspection Scope | |||
During the prior inspection, there was insufficient material to review this commitment. | |||
Subsequently, Entergy completed an operational review for the following new aging | |||
management programs embodied in separate commitments: | |||
#3, Buried Piping and Tanks Inspection Program | |||
#14, Non-EQ Bolted Cable Connections Program | |||
#15, Non-EQ Inaccessible Medium-Voltage | |||
#16, Non-EQ Instrumentation circuits Test Review Program | |||
#17, Non-EQ Insulated Cables and Connections Program | |||
#19, One-Time Inspection Program | |||
#20, One-Time Small Bore Piping Program | |||
#23, Selective Leaching Program | |||
#26, Thermal Aging Embrittlement of Cast Austenitic Stainless Steel (CASS) | |||
Program | |||
# 27, Thermal Aging and Neutron Irradiation Embrittlement of Cast Austenitic | |||
Stainless Steel (CASS) Program. | |||
During this inspection the inspectors reviewed a selected sample of the reviews and | |||
noted each of the programs was subject to an operational review which included Indian | |||
Point specific experience. For example, the Buried Piping Program for Unit 2 was | |||
assessed for a period of six years, 2007 through 2013. This period of time enveloped | |||
the operational experience included in the guidance documents, such as Generic Aging | |||
Lessons Learn (NUREG-1801), Revision 2. External operational experience considered | |||
included license event reports, NRC generic letters, NRC information notices, and | |||
Institute of Nuclear Power Operations (INPO) documents. | |||
Findings and Observations | |||
No findings were identified. | |||
.2.9 Commitment 43: Indian Point Energy Center will review design basis ASME Code | |||
Class 1 fatigue evaluations to determine whether the NUREG/CR-6260 locations that | |||
have been evaluated for the effects of the reactor coolant environment on fatigue usage | |||
are the limiting locations for the Unit 2 and Unit 3 configurations. If more limiting | |||
locations are identified, the most limiting location will be evaluated for the effects of the | |||
Enclosure | |||
7 | |||
reactor coolant environment on fatigue usage. Indian Point Energy Center will use the | |||
NUREG/CR-6909 methodology in the evaluation of the limiting locations consisting of | |||
nickel alloy, if any. | |||
a. Inspection Scope | |||
In the prior inspection, the inspectors noted that Entergy had awarded contracts to | |||
perform calculations to support closure of this commitment. Because the results of the | |||
calculations were not available at the time, the inspectors deferred inspection of this | |||
commitment. | |||
During this inspection the inspectors reviewed calculation CN-PAFM-13-32, Revision 0, | |||
Indian Point Unit 2 (IP2) and Unit 3 (IP3) Refined EAF Analyses and EAF Screening | |||
Evaluations. This calculation was the evaluation of locations previously screened by | |||
calculation CN-PAFM-12-35, Revision 1, Indian Point Unit 2 and Unit 3 EAF Screening | |||
Evaluations, that could be more limiting than the locations identified in | |||
NUREG/CR-6260, Application of NUREG/CR-5999 Interim Fatigue Curves to Selected | |||
Nuclear Power Plants Components. The inspectors noted the CUFen result for the | |||
pressurizer nozzle was 0.999 at 60 years. Entergy was aware that accumulation of | |||
cycles at a rate greater than assumed in the calculation would require a more refined | |||
analysis, application of a non-destructive monitoring technique, or replacement of the | |||
pressurizer nozzle. | |||
Findings and Observations | |||
No findings were identified. | |||
.2.10 Commitment 48: Entergy will visually inspect in-scope underground piping prior to the | |||
period of extended operation and then on a frequency of at least once every 2 years | |||
during the period of extended operation. Visual inspections will be supplemented with | |||
surface or volumetric non-destructive testing if indications of significant loss of material | |||
are observed. Adverse indications will be entered into the plant corrective action | |||
program for evaluation of extent of condition and for determination of appropriate | |||
corrective actions (e.g., increased inspection frequency, repair, or replacement). | |||
a. Inspection Scope | |||
In the prior inspection the inspectors noted that work orders had been issued to perform | |||
the inspections prior to the period of extended operation. The inspectors determined | |||
that additional inspection was merited regarding review of the results of the underground | |||
piping inspections. | |||
The inspectors reviewed the results of selected inspections performed subsequent to the | |||
May 23, 2013, NRC inspection. EN-EP-S-002-MULTI, Attachment 7.2 Pipe/Tank | |||
Coating Visual Inspection Checklist was reviewed for the following lines: | |||

SUMMARY OF FINDINGS
IR 05000247/2013010; 09/09/2013 - 09/12/2013; Indian Point Nuclear Generating Unit 2;
License Renewal Inspection.
This report covers an announced one week inspection, using the guidance provided in NRC
inspection procedure Temporary Instruction 2516/001, Review of License Renewal Activities,
of activities conducted by Entergy to complete commitments made to the NRC as a part of the
Indian Point Energy Center, Unit 2, application for a renewed operating license. The
commitments reviewed during this inspection are recorded in Supplement 1 to NUREG-1930,
Safety Evaluation Report Related to the License Renewal of Indian Point Generating Units
Numbers 2 and 3, Attachment 1, dated August 2011, and in other related correspondence.
Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity
No findings were identified. The inspectors concluded Entergy had made sufficient progress to
complete our review of 44 commitments.

REPORT DETAILS
4. OTHER ACTIVITIES
4OA5 Review of License Renewal Activities (TI 2516/001)
.1 Background
The expiration date of the operating license for Indian Point Unit 2 is midnight on
September 28, 2013. Indian Point Unit 2 meets the criteria in Title 10 of the Code of
Federal Regulations (10 CFR) 2.109(b), Effect of timely renewal application, and will
likely operate beyond the current operating license expiration date. Due to the
Commissions decision to revise the Waste Confidence Decision and Rule and because
of the ongoing Atomic Safety and Licensing Board hearings, the Commission is not
expected to issue a renewed license for Indian Point Unit 2 before the expiration date of
the original license. Therefore, Indian Point would continue operations under the timely
renewal provisions of 10 CFR 2.109(b).
The team used NRC Inspection Manual Temporary Instruction 2516/001 to conduct this
inspection. The Temporary Instruction was written specifically for plants like Indian Point
Unit 2, where the holders of an operating license meet the criteria of 10 CFR 2.109, for
timely renewal, but a final decision by the NRC on the license renewal application is not
expected prior to the period of extended operation. The inspection objectives and
requirements of the Temporary Instruction are to report the status of license renewal
commitment implementation, the status of aging management program implementation,
and to verify the description of programs and activities for managing the effects of aging
are consistent with the Updated Final Safety Analysis Report.
The NRC has conducted three separate license renewal inspections that have reviewed
a total of 44 license renewal commitments. Our first license renewal inspection
conducted during a refueling outage, reviewed four commitments as documented in
NRC Inspection Report 05000247/2012008 (ML12110A315). On May 23, 2013, the
NRC completed a License Renewal Commitment Team Inspection, as documented in
NRC Inspection Report 05000247/2013009 (ML13186A179). The team inspection
concluded that Entergy had made sufficient progress to complete review of
30 commitments and identified 11 commitments that merited further assessment during
a planned follow-up inspection. During the current planned follow-up inspection, the
inspectors completed our review of ten of the 11 commitments identified by the team as
requiring additional review. Commitment 47, one of the 11 commitments previously
identified for additional review, was not assessed during this inspection because Entergy
revised the completion date for this commitment to March 1, 2015, in a letter to the NRC
(ML13142A202).

.2 Commitment Reviews
.2.1 Commitment 6: Enhance the Fatigue Monitoring Program to monitor steady state cycles
and feedwater cycles or perform an evaluation to determine monitoring is not required.
Review the number of allowed events and resolve discrepancies between reference
documents and monitoring procedures.
a. Inspection Scope
In the prior inspection, the inspectors noted that Entergy had awarded contracts to
perform calculations to determine whether monitoring of steady state cycles and
feedwater cycles was required. The inspectors also noted that Entergy planned to
revise procedure 2-PT-2Y015, Thermal Cycle Monitoring Program, if the calculations
demonstrated that a change in the number of allowable steady state cycles and
feedwater cycles was identified.
During this inspection, the inspectors reviewed Westinghouse calculation IPP-13-20,
Revision 1, dated August 14, 2013, reporting the Steady State Fluctuations and
Feedwater Cycling Transient Disposition, presenting LTR-PAFM-13-87, Revision 2.
This result determined that both transients do not significantly affect the fatigue of the
primary system and can be removed from the transient cycle counting program. It was
determined the feedwater cycle transient must still be tracked for the secondary side of
the steam generator and feedwater piping, with a 25,000 cycle limit. The inspectors
verified that procedure 2-PT-2Y015, Thermal Cycle Monitoring Program, Revision 4,
tracked the feedwater cycle transients.
Findings and Observations
No findings were identified.
.2.2 Commitment 13: Enhance the Metal-Enclosed Bus (MEB) Inspection Program to add a
480 volt bus, visually inspect the external surface of MEB enclosure assemblies, include
acceptance criteria, inspect bolted connections, and remove reference to re-torquing
connections from the applicable site procedure.
a. Inspection Scope
In the prior inspection, the inspectors identified that Entergy had not included all
accessible portions of the MEB within the scope of the maintenance inspection program.
The inspectors noted that sections of the emergency diesel generator 480 volt MEB in
the electrical tunnel had not been visually inspected and were not included in the scope
of the maintenance procedure which performed the MEB inspections and tests. As a
result of the NRCs observations, Entergy initiated a Condition Report
(CR-IP2-2013-01786) to revise site procedures and conduct visual inspections of those
additional sections of the bus ducts prior to the period of extended operations.
During this inspection the inspectors reviewed the revised inspection and test
procedures for the portions of the MEB previously considered to be inaccessible. The
Enclosure
3
inspectors reviewed the work orders under which the inspections and tests were
completed for the three MEB sections and corrective action documents which resolved
any identified conditions.
Findings and Observations
No findings were identified.
.2.3 Commitment 19: Implement the One-Time Inspection Program as described in License
Renewal Application, Section B.1.27. This new program will be implemented consistent
with the corresponding program described in NUREG-1801, Section XIM32, One-Time
Inspection.
a. Inspection Scope
In the prior inspection, the inspectors noted the One-Time Inspection Program involved
over 400 inspections. Because Entergy had only completed approximately half of the
planned inspections, the inspectors determined that additional NRC review was merited
to assess the remaining inspection results; any further actions needed, and program
conclusions.
During this inspection the inspectors reviewed the One-Time Inspection Summary
Report, the completed inspection tracking matrix, and 20 additional inspection reports.
The inspectors determined that all inspection results were acceptable and there was no
need for additional action. Further, Entergy concluded that the inspection results
demonstrated that the existing aging management programs for water chemistry and the
diesel fuel monitoring and oil analysis had been effective in managing aging. The test
program results also indicated that additional inspections on components specified in the
License Renewal Application had not identified any unacceptable degradation.
Findings and Observations
No findings were identified.
.2.4 Commitment 23: Implement the Selective Leaching Program as described in License
Renewal Application, Section B.1.33. This new program will be implemented consistent
with the corresponding program described in NUREG-1801, Section XIM33 Selective
Leaching of Materials.
a. Inspection Scope
In the prior inspection, the inspectors noted Entergy was in the progress of completing
selective leaching inspections. The inspectors determined that additional NRC
inspection was merited to review the results of the remaining inspections, any further
actions needed, and program conclusions.
During this inspection, the inspectors reviewed Selective Leaching Summary Report,
including the final sampling plan, the destructive evaluation results of seven
Enclosure
4
components, and associated corrective action documents. Entergy determined that the
visual inspections of 22 gray cast iron components and 17 copper alloy components
showed an absence of selective leaching. However, destructive evaluations
demonstrated that significant selective leaching (i.e., graphitization, had occurred in gray
cast iron components) was occurring. While the commitment actions were complete,
Entergy concluded that they would refine the process and documented a corrective
action to perform engineering evaluations to develop a continuing monitoring program to
manage and evaluate selective leaching.
Findings and Observations
No findings were identified
.2.5 Commitment 26: Implement the Thermal Aging Embrittlement of Cast Austenitic
Stainless Steel (CASS) Program as described in License Renewal Application,
Section B.1.37. This new program will be implemented consistent with the
corresponding program described in NUREG 1801,Section XI.M12, Thermal Aging
Embrittlement of Cast Austenitic Stainless Steel Program.
a. Inspection Scope
In the prior inspection, the inspectors noted that Entergy was planning to screen all cast
austenitic stainless steel components to determine which were potentially susceptible to
a loss of fracture toughness. These components were to be further evaluated, using a
refined analytical technique, to determine the components susceptibility to reduction in
fracture toughness. Entergy chose to perform a unique fracture mechanics analysis of
these components, which was in progress at the time of the prior inspection. The
inspector noted that there may be a question regarding the submittal of the analysis
under ASME requirements, as stipulated in 10 CFR 50.55a.
Subsequently the inspector, in consultation with the Division of License Renewal,
determined submittal of the analysis was not required. During this inspection the
inspectors reviewed the completed evaluation of the screened components
susceptibility to reduction in fracture toughness: Report 1300066.403, Revision 0,
Aging Management of CASS Piping at Indian Point 2, Flaw Tolerance Evaluation of
CASS Piping at Indian Point, dated August 2013. The methodology of probabilistic
fracture mechanics determined a postulated starting reference flaw of one-quarter
thickness would remain below the maximum allowable flaw size during a 60 year life for
all components.
Findings and Observations
No findings were identified.
.2.6 Commitment 27: Implement the Thermal Aging and Neutron Irradiation Embrittlement of
Cast Austenitic Stainless Steel (CASS) Program as described in License Renewal
Application, Section B.1.38. This new program will be implemented consistent with the
Enclosure
5
corresponding program described in NUREG-1801,Section XI.M13, Thermal Aging and
Neutron Embrittlement of Cast Austenitic Stainless Steel program.
a. Inspection Scope
In the prior inspection, the inspectors noted a site document had not been developed
that defined and implemented the screening criteria of Electric Power Research Institute
(EPRI) Technical Report 1013234, Materials Reliability Program: Screening
Categorization, and Ranking of Reactor Internals Components for Westinghouse and
Combustion Engineering PWR Design, (MRP-191), listed in Table 3-5, as applied to the
Indian Point components listed in Table 5-1 of EPRI Report 1022863, Materials
Reliability Program: Pressurized Water Reactor Internals Inspection and Evaluation
Guidelines, (MRP-227-A).
During this inspection the inspectors reviewed Entergy Nuclear Engineering Report:
Indian Point Energy Center: Thermal Aging and Neutron Irradiation Embrittlement of
Cast Austenitic Stainless Steel Aging Management Program, IP-RPT-13-00049,
Revision 0, dated August 14, 2013. This report implemented the above screening
criteria and ranking methodology for Indian Point.
Findings and Observations
No findings were identified.
.2.7 Commitment 33: For the locations identified in License Renewal Application,
Table 4.3-13 (IP2), update the fatigue usage calculations using refined fatigue analyses
to determine if Cumulative Usage Factors (CUF) remain less than 1.0 when accounting
for the effects of reactor water environment, using valid Fen factors.
a. Inspection Scope
In the prior inspection, the inspectors noted that calculations documented in calculation
WCAP 17149-P, Evaluation of Pressurizer Insurge/Outsurge Transients for Indian Point
Unit 2, and WCAP 17199-P, Environmental Fatigue Evaluation for Indian Point Unit 2,
concluded that cumulative fatigue usage factors, including reactor water environment
effects, were below the American Society of Mechanical Engineers (ASME) Code
allowable value of 1.0 for transients postulated for 60 years of operation. The inspectors
noted Entergys action plan included revising the Thermal Cycle Monitoring Program
procedure to reflect changes in the number of projected cycles used in WCAP 17199-P.
During this inspection the inspectors reviewed Indian Point Programs and Components
Engineering Procedure 2-PT-2Y015, Revision 4, Thermal Cycle Monitoring Program.
The inspectors noted the procedure was updated to reflect the number of allowable
cycles derived from the above analysis. The procedure referenced WCAP 17199-P and
included a Table (Attachment 1) that included actual plant cycles rather than the number
of cycles used in the original design calculations. The procedure also was revised to
better reflect operational assumptions used and the bases for the revised calculations of
the WCAP.
Enclosure
6
Findings and Observations
No findings were identified.
.2.8 Commitment 40: Evaluate plant specific and appropriate industry operating experience
and incorporate lessons learned in establishing appropriate monitoring and inspection
frequencies to assess aging effects for the new aging management programs.
Documentation of the operating experience evaluated for each new program will be
available on site for NRC review prior to the period of extended operation.
a. Inspection Scope
During the prior inspection, there was insufficient material to review this commitment.
Subsequently, Entergy completed an operational review for the following new aging
management programs embodied in separate commitments:
- 3, Buried Piping and Tanks Inspection Program
- 14, Non-EQ Bolted Cable Connections Program
- 15, Non-EQ Inaccessible Medium-Voltage
- 16, Non-EQ Instrumentation circuits Test Review Program
- 17, Non-EQ Insulated Cables and Connections Program
- 19, One-Time Inspection Program
- 20, One-Time Small Bore Piping Program
- 23, Selective Leaching Program
- 26, Thermal Aging Embrittlement of Cast Austenitic Stainless Steel (CASS)
Program
- 27, Thermal Aging and Neutron Irradiation Embrittlement of Cast Austenitic
Stainless Steel (CASS) Program.
During this inspection the inspectors reviewed a selected sample of the reviews and
noted each of the programs was subject to an operational review which included Indian
Point specific experience. For example, the Buried Piping Program for Unit 2 was
assessed for a period of six years, 2007 through 2013. This period of time enveloped
the operational experience included in the guidance documents, such as Generic Aging
Lessons Learn (NUREG-1801), Revision 2. External operational experience considered
included license event reports, NRC generic letters, NRC information notices, and
Institute of Nuclear Power Operations (INPO) documents.
Findings and Observations
No findings were identified.
.2.9 Commitment 43: Indian Point Energy Center will review design basis ASME Code
Class 1 fatigue evaluations to determine whether the NUREG/CR-6260 locations that
have been evaluated for the effects of the reactor coolant environment on fatigue usage
are the limiting locations for the Unit 2 and Unit 3 configurations. If more limiting
locations are identified, the most limiting location will be evaluated for the effects of the
Enclosure
7
reactor coolant environment on fatigue usage. Indian Point Energy Center will use the
NUREG/CR-6909 methodology in the evaluation of the limiting locations consisting of
nickel alloy, if any.
a. Inspection Scope
In the prior inspection, the inspectors noted that Entergy had awarded contracts to
perform calculations to support closure of this commitment. Because the results of the
calculations were not available at the time, the inspectors deferred inspection of this
commitment.
During this inspection the inspectors reviewed calculation CN-PAFM-13-32, Revision 0,
Indian Point Unit 2 (IP2) and Unit 3 (IP3) Refined EAF Analyses and EAF Screening
Evaluations. This calculation was the evaluation of locations previously screened by
calculation CN-PAFM-12-35, Revision 1, Indian Point Unit 2 and Unit 3 EAF Screening
Evaluations, that could be more limiting than the locations identified in
NUREG/CR-6260, Application of NUREG/CR-5999 Interim Fatigue Curves to Selected
Nuclear Power Plants Components. The inspectors noted the CUFen result for the
pressurizer nozzle was 0.999 at 60 years. Entergy was aware that accumulation of
cycles at a rate greater than assumed in the calculation would require a more refined
analysis, application of a non-destructive monitoring technique, or replacement of the
pressurizer nozzle.
Findings and Observations
No findings were identified.
.2.10 Commitment 48: Entergy will visually inspect in-scope underground piping prior to the
period of extended operation and then on a frequency of at least once every 2 years
during the period of extended operation. Visual inspections will be supplemented with
surface or volumetric non-destructive testing if indications of significant loss of material
are observed. Adverse indications will be entered into the plant corrective action
program for evaluation of extent of condition and for determination of appropriate
corrective actions (e.g., increased inspection frequency, repair, or replacement).
a. Inspection Scope
In the prior inspection the inspectors noted that work orders had been issued to perform
the inspections prior to the period of extended operation. The inspectors determined
that additional inspection was merited regarding review of the results of the underground
piping inspections.
The inspectors reviewed the results of selected inspections performed subsequent to the
May 23, 2013, NRC inspection. EN-EP-S-002-MULTI, Attachment 7.2 Pipe/Tank
Coating Visual Inspection Checklist was reviewed for the following lines:
