Licensee Action on Previous Inspection Findings a. (Closed) Violation 269/81-16-01, "Failure to control welding electrodes and maintain appropriate environmental conditions around the welding area".

Duke Power Company (DPC)

letter of response dated October 2, 1981 has been reviewed and determined to be acceptable by Region I The inspector held discussions with the Senior QA Engineer and examined the corrective actions as stated in the letter of respons The inspector concluded that DPC had determined the full extent of the subject noncompliance, performed the necessary survey and follow-up actions to correct the present conditions, and developed the necessary corrective actions to preclude recurrence of similar circumstance The corrective actions identified in the letter of response have been implemente (Closed) Violation 269/81-16-02, "Failure to maintain required cleanliness in the Transfer Canal Area."

Duke Power Company (DPC)

letter of response dated October 2, 1981 has been reviewed and determined to be acceptable by Region II. The inspector held discussions with the Senior QA Engineer and examined the corrective

actions as stated in the letter of response. The inspector concluded that DPC had determined the full extent of the subject noncompliance, performed the necessary survey and follow-up actions to correct the present conditions, and developed the necessary corrective actions to preclude recurrence of similar circumstances. The corrective actions identified in the letter of response have been implemente c. (Closed)

Violation 269/81-24-01, "Failure to verify the qualification of NDE personnel". Discussions with the QA Manager Operations and additional information provided in the licensee's response dated December 4, 1981, along with a review of the approved contractor's program have provided adequate assurance that the requirements of ASME Section XI (74S75),

IWA-1400 are being me.

Unresolved Items Unresolved items were not identified during this inspectio.

Licensee Action on Inspector Follow-up Items (IFI) (Closed)

IFI 269/270/287/81-05-05,

"Penetration Weld Deficiencies".

The inspector reviewed weld repair records and witnessed surface examination (MT)

of penetration number P-6 MT was chosen as an alternative to radiography because weld location precluded meaningful radiographic examination of the repai.

Independent Inspection Effort Hanger Inspection, Safe Shutdown Facility (SSF), Unit 1. Hangers installed during this outage to accommodate piping involved in the SSF modification were selected for observation/inspection and record review to ascertain compliance with approved engineering drawings procedures and Code(s) as applicabl Hanger type and line location, is identified on approved engineering drawings, e.g., O-1RB-NSM 1012-20 Rev. 1, while hanger specific details are addressed on hanger sketches which are used for fabrication and field installation purpose Installed hangers are inspected per requirements of procedure QCF-2 Revision 8, "Piping System Layout and Hanger Installation Inspection".

Subsequent to QC inspections, each installation package is reviewed by site QA prior to turning it over to steam productio Hangers from the feedwater and reactor makeup systems were selected for observation/inspection and record revie These were identified as follows:

HANGER & SKETCH N SYSTEM TYPE 1-51-478E-H6100 Rev. 1 RC Makeup Spring 1-51-478E-H6101 Rev. 0 RC Makeup Rigid 1-51-478E-H6105 Rev. 1 RC Makeup Anchor 1-51-478E-H6112 Rev. 2 RC Makeup Snubber 1-51-478E-H6136 Rev. 1 RC Makeup Rigid 1-51-478E-H6137 Rev. 2 RC Makeup Rigid NPS-03-1-0-478-H24, Rev. 0 Feedwater Rigid NPS-03-0-480-H44, Rev. 1 Feedwater Var. Spring NPS-1-03-479F-H6018, Rev. 1 Feedwater Var. Spring NPS-1-03-479F-H6019, Rev. 0 Feedwater For these hangers the inspector observed hanger location, identification, type and as-built dimensions for compliance with drawing/sketche Also the inspector reviewed quality related records for hanger materials, e.g.,

spring cans, plate, weld consumable, et Qualification of inspection personnel and welders were also reviewed and found to be in order. Within these areas the inspector noted that the quality record for E7018, 3/32" filler metal, produced from HT #432L7091, did not include mechanical test results for the stress relieved condition. This was contrary to site policy in that there is no control over material to be or not to be used on post weld heat treat application Discussions between the licensee and the material manufacturer disclosed that the lot in question had been tested in the stress-relieved condition and the results were forwarded to the sit In addition the inspector requested and the licensee agreed to research the files for similar material which may have been furnished with similar documentation. This effort began immediately and was still in progress at the completion of this inspectio No violations or deviations were identifie.

Inservice Inspection - Unit 1 Hydrostatic Pressure Testing Records of hydrostatic tests performed on Class 1 and 2 pipe systems as required by ASME Section XI 1974, IWA-2400 were reviewed for compliance with Code and procedural requirement Systems selected included Building Spray, Low Pressure Injection and Purification and Deborating Demineralizer Within these areas the inspector reviewed system boundaries as depicted on drawings PO-103A-1 Rev. 10, PO-102A-1 Re,

PO-101A Re,

PO-101B1 Re and PO-109A-1 Re,

respectively, procedures, QC signoffs, hydro pressures, times, temperatures and completion dates. The inspector noted that the ANI had witnessed the testing and approved the result Site QA had reviewed and approved the final record *

4 ISI Data Review and Evaluation (Unit 1)

This work effort was a follow-up to that reported in RII reports 50-269/81-16, and 50-269/81-2 ASME Section XI (74S75)

as required by 10 CFR 50.55(a) paragraph (g) is the code governing this activit The review involved radiographs of welds in Class 2 pipe systems inspected during this outage and found to contain Code unacceptable indications. The welds were nonconformed, repaired and reradiographe The welds involved were as follows:
