Clarification for RAI 3.0.3.1.6-1 Part 1 NL-11-096 Page 1 of 3 This clarification amends the response in letters NL-11-032, dated March 28, 2011; NL-11-074, dated July 14, 2011; and NL-11-090, dated July 27,2011. These letters revised LRA Section A.2.1.22, A.3.1.22 and 8.1.23.
This letter revises LRA Sections A.2.1.22, A.3.1.22, and 8.1.23.
Clarification is provided on the performance of event-driven inspections for water in cable manholes. Letter NL-11-032 correctly identified event-driven inspections as part of the Non-EQ Inaccessible Medium-Voltage Cable Program. Minor clarifications are provided to the program description in LRA Section 8.1.23 provided in letter NL-11-032. In addition, LRA sections A.2.1.22 and A.3.1.22 are revised to clearly state that even-driven inspections are part of the program.
A.2.1.22 Non-EQ Inaccessible Medium-Voltage Cable Program The Non-EO Inaccessible Medium-Voltage Cable Program is a new program that entails periodic and event-driven inspections for water collection in cable manholes, and periodic testing of cables. In scope medium-voltage cables (cables with operating voltage from 2kV to 35kV) and low-voltage power cables (400 V to 2 kV) exposed to significant moisture will be tested at least once every six years to provide an indication of the condition of the conductor insulation. Test frequencies are adjusted based on test results and operating experience.
The frequency of inspections for water accumulation in manholes is established based on plant specific operating experience 'Nith cable wetting or submergence in manholes (Le., the inspection is performed periodically based on 'Nater accumulation over time and event driven occurrences, such as heavy rain or flooding).
The frequency will be program includes periodic inspections for water accumulation in manholes at least once every year (annually). In addition to the periodic manhole inspections, manhole inspection for water after events, such as heaw rain or flooding will be performed. Inspection frequency will be increased as necessary based on evaluation of inspection results.
The Non-EQ Inaccessible Medium-Voltage Cable Program will be implemented prior to the period of extended operation. This new program will be implemented consistent with the corresponding program described in NUREG-1801,Section XI.E3, Inaccessible Medium-Voltage Cables Not Subject To 10 CFR 50.49 Environmental Qualification Requirements.
A.3.1.22 Non-EQ Inaccessible Medium-Voltage Cable Program The Non-EO Inaccessible Medium-Voltage Cable Program is a new program that entails periodic and event-driven inspections for water collection in cable manholes, and periodiC testing of cables. In scope medium-

The Non-EO Inaccessible Medium-Voltage Cable Program will be implemented prior to the period of extended operation. This new program will be implemented consistent with the corresponding program described in NUREG-1 8001,Section XI.E3, Inaccessible Medium-Voltage Cables Not Subject To 10 CFR 50.49 Environmental Oualification Requirements.
B.1.23 NON-EQ INACCESSIBLE MEDIUM-VOLTAGE CABLE Program Description The Non-EO Inaccessible Medium-Voltage Cable Program is a new program that entails periodic inspections for water collection in cable manholes and periodic testing of cables. In scope medium-voltage cables (cables with operating voltage from 2kV to 35kV) and low-voltage power cables (400 V to 2 kV) exposed to significant moisture will be tested at least once every six years to provide an indication of the condition of the conductor insulation. Test frequencies will be adjusted based on test results and operating experience. The program includes inspections for water accumulation in manholes at least once every year (annually). In addition to the periodic manhole inspections, manhole inspection for water fef-after events driven ossurronses, such as heavy rain or flooding will be performed. Inspection frequency will be increased as necessary based on evaluation of inspection results.
This program will be implemented prior to the period of extended operation.
Operating Experience The Non-EQ Inaccessible Medium-Voltage Cable Program is a new program. Industry and plant-specific operating experience will be considered when implementing this program. Industry operating experience that forms the basis for the program is described in the operating experience element of the NUREG-1801 program description. IPEC plant-specific operating experience is not inconsistent with the operating experience in the NUREG-1801 program description.
The inspection frequency for manholes is based on plant-specific operating experience with cable wetting or submergence in manholes (i.e., the inspection is performed periodically based on water accumulation over time and following events such as heavy rain or flooding).
The IPEC program is based on the program description in NUREG-1801, which in turn is based on industry operating experience. As such, operating experience provides assurance that the Non-EO Inaccessible Medium-Voltage Cable Program will manage the effects of aging such that applicable components will
NL-11-096 Page 3 of 3 continue to perform their intended functions consistent with the current licensing basis through the period of extended operation.
Conclusion The Non-EO Inaccessible Medium-Voltage Cable Program will be effective for managing aging effects since it wi" incorporate proven monitoring techniques and industry and plant-specific operating experience. The Non-EO Inaccessible Medium-Voltage Cable Program assures that the effects of aging will be managed such that the applicable components wi" continue to perform their intended functions consistent with the current licensing basis through the period of extended operation.
Clarification for RAI3.1.2.2.16-1 band RAI3.1.2.2.16-1 Part 2 Commitment 42 was inadvertently changed due to an administrative error in the list of regulatory commitments attached to NL-11-07 4. The revision had not been identified as a change to the responses to RAls 3.1.2.2.16-1 band RAI 3.1.2.2.16-1 Part 2 as documented in NL-11-032. These RAI responses accurately describe the intended program and associated commitment. The list of regulatory commitments has been changed to be consistent with the RAI responses.
Commitment 42 IPEC wi" develop a plan for each unit to address the potential for cracking of the primary to secondary pressure boundary due to PWSCC of tube-to-tubesheet welds using one of the following two options.
Each plan 'Nill consist of two options.
Option 1 (Analysis)
IPEC wi" perform an analytical evaluation of the steam generator tube-to-tubesheet welds in order to establish a technical basis for either determining that the tubesheet cladding and welds are not susceptible to PWSCC, QLredefining the pressure boundary in which the tube-to-tubesheet weld is no longer included and, therefore, is not required for reactor coolant pressure boundary function. The redefinition of the reactor coolant pressure boundary must be approved by the NRC as a license amendment request.
Option 2 (Inspection)
IPEC will perform a one-time inspection of a representative number of tube-to-tubesheet welds in each steam generator to determine if PWSCC cracking is present. If weld cracking is identified:
- a. The condition will be resolved through repair or engineering evaluation to justify continued service, as appropriate, and
- b. An ongoing monitoring program will be established to perform routine tube-to-tubesheet weld inspections for the remaining life of the steam generators.

COMMITMENT 42 IPEC will develop a plan for each unit to address the potential for cracking of the primary to secondary pressure boundary due to PWSCC of tube-to-tubesheet welds using one of the following two options.
EaGh plan will Gonsist of two options.
Option 1 (Analysis)
IPEC will perform an analytical evaluation of the steam generator tube-to-tubesheet welds in order to establish a technical basis for either determining that the tubesheet cladding and welds are not susceptible to PWSCC, or redefining the pressure boundary in which the tube-to-tubesheet weld is no longer included and, therefore, is not required for reactor coolant pressure boundary function. The redefinition of the reactor coolant pressure boundary must be approved by the NRC as a license amendment request.
Option 2 (Inspection)
IPEC will perform a one-time inspection of a representative number of tube-to-tubesheet welds in each steam generator to determine if PWSCC cracking is present. If weld cracking is identified:
- a. The condition will be resolved through repair or engineering evaluation to justify continued service, as appropriate, and
- b. An ongoing monitoring program will be established to perform routine tube-to-tubesheet weld inspections for the remaining life of the steam generators.
43 IPEC 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 IP2 and I P3 configurations. If more limiting locations are identified, the most limiting location will be evaluated for the effects of the reactor coolant environment on fatigue usage.
IPEC will use the NUREG/CR-6909 methodology in the evaluation of the limiting locations consisting of nickel alloy, if any.
