USNRC Generic Letter 88-01 and Supplement 1 (b)
NUREG-0313 Revision 2 The purpose of this letter is to provide Comed's assessment of the indications detected in eight (8) Inter Granular Stress Corrosion Cracking (IGSCC) susceptible stainless steel weldments in the reactor recirculation piping system and to transmit the weld overlay repair designs and the flawed pipe evaluations. In addition, we have included our response to the NRC's questions from the April 1,1996 teleconference between Comed and the NRC.
j Ultrasonic examinations (UT) on IGSCC susceptible weldments were performed during the current QlR14 refuel outage and resulted in eight (8) welds with indications that exceed the acceptance criteria in IWB-3500 of ASME Section XI 1989 Edition. Subsequently, the j
weldments were evaluated using the methodology and acceptance criteria specified in IWB-3640 of ASME Section XI,1989 Edition and/or were scheduled for weld overlay repairs during the current refuel outage. The repairs will consist of a " designed" weld overlay or a
" standard" weld overlay in accordance with Reference (b). The flawed pipe evaluations concluded that a minimum of five (5) hot operating years remain prior to exceeding the allowable flaw size for "wek'ments evaluated for continued service". The Engineering Change Notices (ECN) and Engineering Calculations are included as Attachments 1 and 2.

ESK-96 049 April 4,1996 In addition, the following are responses to the questions that the NRC asked during the April 1,1996 teleconference call between Comed and the NRC.
Question 1)
Why were Category D welds not included in the sample expansion based on the results from Category C weld inspections?
Response 1)
Quad Cities Station has committed to perform IGSCC inspections in accordance to the rules of Generic Letter 88-01. The NRC Position on Sample Expansion, which is found on page 5 of the Generic Letter, only requires additional welds of the same IGSCC Category (Category A, B, or C) as that of the flawed welds be selected for any additional samples. Supplement I to Generic Letter 88-01, issued in February 4,1992, provides clarification on the sample expansion rules applicable to IGSCC Category D welds. Supplement 1 does not discuss nor require a sample expansion to include welds in a different IGSCC Category than that of the flawed welds.
During the current refuel outage Q1R14, the Category C sample was expanded twice to include 100% of the Category C welds.
Question 2)
What is the population of Category D Welds?
Response 2)
The total population count for Category D welds in Quad Cities Unit 1 is seven (7) w ' Ids. They are: 02 A-S4, 02 AB-S 10A, 02 AD-S5, 02 BB-S 10, 02 BD-SS, 10HV-F1, and 10S-S3. These Category D welds are included in the original IGSCC UT sample for the current refuel outage, Q1R14.
In conclusion, per the requirements of Reference (a), Comed requests NRC review and acceptance of a return to operating mode of Quad Cities Unit 1 at the end of the scheduled refueling outage. NRC acceptance is requested by April 27,1996.
Please address any further comments or questions regarding this matter to this office.

Description I
4.1.1 Core sample plug repairs shall be in accordance with Section 4.2 of Part 4 of this ECN.
l l
4.1.2 Weld overlay application shall be in accordance with page 9 of this ECN (Sketch 1598-00044.010-0207) and shall comply with the technical requirements contained in-Document No. COE-107-500, Latest Revision.
4.1.3 Detailed joint configuration information and thickness data shall be reported to Engmeenng Dn9I to application of the overlay.
i 4.1.4 During weld overlay implementation, the "as-built" configuration shall be recorded on a Weld Overlay Data Sheet as specified in Document No. COE-107-500, Latest Revision.
4.1.5 The base materials to which this WOR is to be applied contain low levels of delta ferrite (<5 FN). In an effort to compensate for the dilution effect this low ferrite material will have on deposited weld metal, it is recommended that the weld filler material used for the first layer be selected on the basis of its ability to produce a deposit meeting the requirements of Document No. COE-107-500 (minimum 7.5 FN as-deposited). For the first layer, it may therefore be necessary to use filler material capable of producing an undiluted weld deposit double the minimum acceptable delta ferrite specified in COE-107-500.
4.2 Core Plug Renair 4.2.1 This Section describes requirements for the removal of existing plug connections (reference Typical Plug Connection Detail, this ECN page 8) originally installed to cover core samples removed from weldment 02BS-S12 in the mid-1980's. These plug connections will be removed and replaced with backing plugs (reference Backing Plug Installation Detail, this ECN page 8) which in turn will be covered by the weld overlay repair described in Sketch 1598-00044.010-0207 (this ECN page 9).

Description 4.1.1 Weld overlay application shall be in accordance with page 6 of this ECN (Sketch 1598-00044.010-0208) and shall comply with the technical requirements contained in Document No. COE-107-500, Latest Revisica.
4.1.2 Detailed joint configuration information and thickness data shall be reported to Engineering pIigt to application of the overlay.
4.1.3 During weld overlay implementation, the "as-buil " configuration shall be recorded on a Weld Overlay Data Sheet as specified in Document No. COE-107-500, I.atest Revision.
4.1.4 The base materials to which this WOR is to be applied contain low levels of delta ferrite (<5 FN). In an effort to compensate for the dilution effect this low ferrite material will have on deposited weld metal, it is recommended that the weld filler material used for the first layer be selected on the basis of its ability to produce a deposit meeting the requirements of Document No. COE-107-500 (minimum 7.5 FN as deposited). For the first layer, it may therefore be nereamry to use filler material capable of producing an undiluted weld deposit double the mindmum acceptable delta ferrite specified in COE-107-500.

4.1.4 The base materials to which this WOR is to be applied contain low levels of delta ferrite (<5 FN). In an effort to compensate for the dilution effect this low ferrite material will have on deposited weld metal, it is recommended that the weld filler matenal used for the first layer be selected on the basis of its ability to produce a deposit meeting the requirements of Document No. COE-107-500 (minimum 7.5 FN -
as-deposited). For the first layer, it may therefore be necessary to use filler material capable of producin; an undiluted weld deposit double the minimum acceptable delte.

Description 4.1.1 Weld overlay application shall be in accordance with page 6 of this ECN (Sketch 1598-00044.010-0214) and shall comply with the technical requirements contained in Document No. COE-107-500, Latest Revision.
4.1.2 Detailed joint configuration information and thickness data shall be reported to Engineering yngI to application of the overlay.
4.1.3 During weld overlay implementation, the "as-built" configuration shall be recorded on a Weld Overlay Data Sheet as specified in Document No. COE-107-500, Latest Revision.
4.1.4 The base materials to which this WOR is to be applied contain low levels of delta ferrite (<5 FN). In an effort to compensate for the dilution effect this low ferrite material will have on deposited weld metal, it is recommended that the weld filler material used for the first layer be selected on the basis ofits ability to produce a deposit meeting the requirements of Document No. COE-107-500 (minimum 7.5 FN as-deposited). For the first layer, it may therefore be necessary to use filler material capable of producing an undiluted weld deposit double the minimum acceptable delta ferrite specified in COE-107-500.

SUPPORT INFORMATION (Part 4)
ECN No. 04-01346M Desigo Change No.: E04-1-96-023-H Page 5 of 6 4.1 General Note No.
Description 4.1.1 Weld overlay application shall be in accordance with page 6 of this ECN (Sketch 1598-00044.010-0212) and shall comply with the tar hair al requirements contained in Document No. COE-107-500, Latest Revision.
i 4.1.2 Detailed joint configuration information and thickness data shall be reported to Engineering gig to application of the overlay.
4.1.3 During weld overlay implementation, the "as-built" configuration shall be recorded on a Weld Overlay Data Sheet as specified in Document No. COE-107-500, I.atest Revision.
4.1.4 The base materials to which this WOR is to be applied contain low levels of delta ferrite (<5 FN). In an effort to compensate for the dilution effect this low ferrite material will have on deposited weld metal, it is recommended that the weld filler j
material used for the first layer be selected on the basis ofits ability to produce a deposit meeting the requirements of Document No. COE-107-500 (minimum 7.5 FN as-deposited). For the first layer, it may therefore be necessary to use filler material capable of producing an undiluted weld deposit double the minimum acceptable delta ferrite specified in COE 207-500.
