NL-17-060 Attachment 1 Page 1 of 5 RAI B.1.35-1

Background

By letter dated January 17, 2017, the applicant submitted the changed status of Commitments 41 and 42 for Indian Point Unit 2 and Unit 3 (IP2 and IP3 respectively). Previously, the applicant identified these license renewal commitments to manage cracking due to primary water stress corrosion cracking (PWSCC) for steam generator divider plates and tube-to-tubesheet welds. The January 17, 2017, letter indicates that the applicant eliminated Commitment 41 (regarding divider plates) and closed Commitment 42 (regarding tube-to-tubesheet welds) based on License Renewal Interim Staff Guidance (LR-ISG) 2016-01, "Changes to Aging Management Guidance for Various Steam Generator Components."

In the letter, the applicant also provided proprietary information to demonstrate that the industry analyses in EPRI Report 3002002850 are applicable and bounding for the applicant's units (as discussed in LR-ISG-2016-01). EPRI Report 3002002850 describes industry analyses of potential crack initiation and propagation in steam generator head components (e.g., divider plate cracking into the steam generator head). The EPRI report also addresses the implication of the potential cracking for the integrity of reactor coolant pressure boundary, taking into account material's resistance to PWSCC (e.g., resistance of Alloy 690) and steam generator loading conditions.

In addition, Tables 4-2 and 4-3 of EPRI Report 3002002850 identify the turbine roll test as one of the bounding thermal transients for the industry analyses. LRA Tables 4.3-1 and 4.3-2 describe design transients for ASME Class 1 fatigue analysis for IP2 and IP3, respectively.

LRA Table 4.3-1 indicates that the number of turbine-roll-test cycles analyzed for IP2 is 20 cycles. LRA Table 4.3-2 indicates that the turbine-roll-test transient is not a design transient for IP3.

In its review of the applicant's information, the staff noted the following concerns:

  • The number of turbine-roll-test cycles analyzed in EPRI Report 3002002850 is less than that analyzed for IP2 in LRA Table 4.3-1 (i.e., 20 cycles). This indicates that the loading conditions analyzed in the EPRI report for this transient may not bound the IP2 loading conditions.
  • Given that the LRA Table 4.3-2 does not identify the turbine roll test as an IP3 design transient for ASME Class 1 fatigue analysis, it is not clear how the applicant ensures the loading conditions at IP3 are bounded by those analyzed in EPRI Report 3002002850 in terms of the turbine-roll-test transient.

NL~17-060 Attachment 1 Page 2 of 5 RAI B.1.35-1. Request 1 Explain why the IP2 steam generator loading conditions are bounded by those analyzed in EPRI Report 3002002850 even though the number of turbine-roll-test cycles analyzed in the EPRI report is less than that analyzed for IP2 in LRA Table 4.3-1.

Response

A turbine roll test is a test performed during initial hot functional testing prior to commercial plant operation. The IP2 cycle counting program conservatively assumes that one turbine roll test was performed at IP2. IP2 has no plans to perform any additional turbine roll tests during its remaining operating life. IP2 has revised the cycle counting program to reduce the number of allowable turbine roll tests from 20 to 10 to be consistent with the EPRI analysis.

The steam generators at IP2 were replaced in 2000. The turbine roll test transient only occurs during plant hot functional testing; therefore, the IP2 replacement steam generators have not experienced and will not experience a turbine roll test transient. Because the IP2 replacement steam generators were installed after any turbine roll tests would have been performed, the loading conditions at IP2 are bounded by the loading conditions analyzed in EPRI Report 3002002850.

RAI B.1.35-1. Request 2 Discuss how the applicant ensures that the loading conditions at IP3 are bounded by those analyzed in EPRI Report 3002002850 in terms of the turbine-roll-test transient.

Response

A turbine roll test is a test performed during initial hot functional testing prior to commercial plant operation. The turbine roll test transient was not tracked prior to submittal of the license renewal application and therefore, was not included in LRA Table 4.3-2. Turbine roll test transients have since been added to the IP3 cycle counting program.

The IP3 cycle counting program conservatively assumes that five turbine roll tests were performed at IP3. IP3 has no plans to perform any additional turbine roll tests during its remaining operating life. The IPEC cycle counting procedure has a limit of 5 turbine roll test transient cycles for IP3, so IP3 is bounded by the EPRI analysis.

The steam generators at IP3 were replaced in 1989. The turbine roll test transient only occurs during plant hot functional testing; therefore, the IP3 replacement steam generators have not experienced and will not experience a turbine roll test transient. Because the IP3 replacement steam generators were installed after any turbine roll tests would have been performed, the loading conditions at IP3 are bounded by the ,loading conditions analyzed in EPRI Report 3002002850.

NL-17-060 Attachment 1 Page 3 of 5 RAI 8.1.35-2

~ Background By letter dated January 17, 2017, the applicant submitted information on the changed status of Commitments 41 and 42 for Indian Point Unit 2 and Unit 3. As the applicant's letter notes, the staff recently issued License Renewal Interim Staff Guidance (LR-ISG) 2016-01, "Changes to Aging Management Guidance for Various Steam Generator Components". LR-ISG-2016-01 includes the following guidance on aging management for steam generator components.

  • Visual inspections: steam generator head internal areas (head interior surfaces, divider plate assemblies, tubesheets (primary side) and tube-to-tubesheet welds) are inspected to identify signs of cracking or loss of material (e.g., rust stains and distortion of divider plates). GALL Report AMP Xl.M19, "Steam Generators,." which includes these visual inspections, is used to manage (a) loss of material due to boric acid corrosion for channel heads and tubesheets and (b) cracking due to primary water stress corrosion cracking (PWSCC) for divider plate assembles and tube-to-tubesheet welds.
  • Frequency of the visual inspections: at least every 72 effective full power months or every third refueling outage, whichever results in more frequent inspections.

The staff needs to confirm whether the applicant's Steam Generator Integrity Program is consistent with the guidance in LR-ISG-2016-01.

RAI B.1.35-2. Request 1 Clarify whether the Steam Generator Integrity Program is consistent with the guidance discussed above (i.e., conduct of visual inspections to manage loss of material and cracking due to PWSCC; visual inspection frequency; and implementation of or plans for implementation of the EPRI steam generator guidelines by the industry-provided implementation dates). If the program is not consistent with the guidance, provide justification for why the applicant's program is adequate for aging management.

Response

The IPEC Steam Generator Integrity Program will be updated to require general visual inspections of the steam generator channel head. These visual inspections provide an opportunity to identify cracking if it were to grow into pressure boundary components

NL-17-060 Attachment 1 Page 4 of 5 through identification of rust stains and gross cracking or distortion of the divider plate assembly.

Visual inspections will be performed whenever the steam generator primary side is opened for eddy current inspections. At IP2, the frequency is at least once every 48 effective full p'ower months per Technical Specification 5.5.7.d.2. At IP3, the frequency is at least once every 72 effective full power months (which is every third refueling outage) per Technical Specification 5.5.8.d.2.

I' IPEC implements the EPRI steam generator guidelines, including: (a) EPRI Report 1022832 (primary-to-secondary leak guidelines); (b) EPRI Report 1025132 (in-situ pressure test guidelines); (c) EPRI Report 1019038 (integrity assessment guidelines); and (d) EPRI Report 1013706 (examination guidelines). The IPEC Steam Generator Integrity Program is being revised to implement (c) EPRI Report 3002007571 (integrity assessment guidelines);

and (d) EPRI Report 3002007572 (examination guidelines) within the timeframes required by the EPRI Steam Generator Management Program (~GMP) in accordance with NEI 97-06 Rev 3 and NEI 03-08 Rev 2 and 3.

  • RAI B.1.35-2. Request 2 Discuss whether the Steam Generator Integrity Program is used to manage cracking due to PWSCC for divider plate assemblies (LRA item 3.1.1-81) and tube-to-tubesheet welds (LRA item 3.1.1-35).

Response

As indicated in LRA item 3.1.1-81, the Water Chemistry Control - Primary and Secondary Program manages cracking of the nickel-alloy steam generator divider plate exposed to reactor coolant. Aging management review results do not credit the Steam Generator Integrity Program to manage cracking of the divider plate due to PWSCC because the program does not include VT-1 or volumetric examinations that are qualified for detection of small cracks resulting from PWSCC. However, consistent with LR-ISG-2016-01 recommendations, the IPEC Steam Generator Integrity Program will be enhanced to specify a general visual inspection of the steam generator channel head.

For the steam generator tubesheets, which are steel with nickel alloy cladding, cracking is managed by the Water Chemistry Control - Primary and Secondary, and the Steam Generator Integrity Programs. This position is documented in LRA item 3.1.1-35.

In the IP3 spring 2017 refueling outage, a general visual inspection was performed on the steam generator channel head, divider plate assembly, and tube-to-tubesheet welds in all 4 steam generators looking for evidence of cracking. The inspection was specifically performed to satisfy the recommendations of LR-ISG-2016-01. The purpose of the visual

,inspection was to identify rust stains or other abnormal conditions which could indicate the presence of cracking. The visual inspection was satisfactory with no evidence of rust stains I

L

NL-17-060 Attachment 1 Page 5 of 5 or other abnormal conditions which would indicate the presence of cracking. The general visual inspection identified no cracking or distortion of the divider plate.

A similar inspection is planned for IP2 in the spring 2018 refueling outage.

RAI B.1.35-2. Request 3 Provide updated description of UFSAR supplement for the Steam Generator Integrity Program as necessary. As part of the response, clarify whether the program is consistent with Revision 3 of NEI 97-06 "Steam Generator Program Guidelines."

Response

The IPEC Steam Generator Integrity Program is consistent with Revision 3 of NEI 97-06 "Steam Generator Program Guidelines."

The License Renewal Application requires changes due to the responses to this Request for Information. These changes are contained in Attachment 2. The IP3 UFSAR will be revised in the biennial update due in September 2017, and the IP2 UFSAR will be revised in the biennial update due in September 2018.
