o Docket Nos. 50-325/324 LICENSEE: Carolina Power and Light Company (CP&L)
FACILITY: Brunswick Steam Electric Plant, Units 1 and 2
SUBJECT:
SUMMARY
OF MEETING HELD ON NOVEMBER 3,1986: PIPE REPAIR FOR INTERGRAhULAR STRESS CORROSION CRACKING (IGSCC)
Background
Discussions were held with CP&L and its contractors on November 3, 1986 regarding the possible use of pipe locks to repair welded joints at Brunswick 1 and 2. The list of attendees is provided in Enclosure 1.
Brunswick I will be shutdown for a maintenance and refueling outage on February 13, 1987. During that outage, inspections will be performed to determine the existence of intergranular stress corrosion cracking (IGSCC) in Inconel weld butter in reactor coolant system pipe welds. Brunswick 2 is currently operating in Fuel Cycle 7 with unrepaired cracks in two nozzel-to-safe-end welds. Approval for continued operation for the duration of Fuel Cycle 7 was granted by the NRC in a letter dated October 5, 1986. Brunswick 2 reactor coolant system pipe welds will be re-examined at the end of Fuel Cycle 7.
CP&L is considering the use of pipe locks as a possible method of pipe repair in the event that unacceptable crack indicaticns are identified in Inconel butter joints in the Unit I and 2 IGSCC inspections. Consequently, CP&L requested that a meeting be held with the NRC staff to identify NRC concerns with the use of pipe locks and the information that would be required in a submittal to obtain NRC approval for the use of pipe locks.
Meeting Summary Some background information on the design and use of pipe locks at other nuclear power facilities was presented by Mr. William O'Donnel of 0'Donnell &
Associates, Inc. (0DAI), a CP&L contractor. ODAI is the developer of pipe locks and patent-holder for the design. CP&L stated the position that pipe locks are superior to weld overlay repair and are thus an acceptable long-term repair method for reactor coolant piping susceptible to IGSCC. One benefit accruir.g from the use of pipe locks relative to weld overlays is that pipe lock installation does not preclude future inspection of the original weld.
Copies of the slides used in the CP&L presentation are provided as Enclosure 2.

The use of pipe locks at other nuclear power facilities has-been done on a trial basis in areas where NRC approval was not required. That is, pipe locks have been used in conjunction with weld overlay where the weld overlay was the primary method of pipe repair and satisfied NRC criteria. NRC approval has not been granted for the use of pipe locks as the sole method of pipe repair at any facility. The current position of the NRC staff is that pipe locks are not an ASME-prescribed repair method for pipes but could be approved as an acceptable alternate to weld overlay repair if adequate justification is provided.
CP&L committed to provide justification for a representative use of pipe locks at the Brunswick facility prior to the start of the Unit I refueling outage, i.e. , before February 13, 1987. Additional information on the specific installations used at Brunswick 1 (if any) will be provided along with a request for approval to restart prior to startup from the outage in June 1987.

INSPECTABILITY O
THE PIPELOCK ITSELF CAN BE EXAMINED PER ASME XI REQUIREMENTS.AS AN ADDED MEASURE OF CONSERVATISM THE PIPELOCK IS DESIGNED FOR OPTIMUM INSPECTABILITY OF THE ORIGINAL WELD, 0 THE PIPELOCK, WHEN REMOVED, WILL NOT INTERFERE WITH UT --
EXAMINATION TECHNIQUES RECOMMENDED BY EPRI/BWROG, IGSCC RESEARCH PROJECT T-301-2, DEVELOPMENT OF IMPROVED PROCEDURE FOR EXAMINATION OF DISSIMILAR METAL WELDS IN BWR N0ZZLE-TO-SAFE-END WELD.
O THE GROOVES THAT-ENABLE THE PIPELOCK TO ADEQUATELY GRIP THE PIPE ARE DESIGNED TO ALLOW EXAMINATION TO THE WELD ROOT WITH A 60 TRANSDUCER.
O THE SURFACE FINISH, WHICH IS EXTREMELY CRITICAL TO IGSCC DETECTION AND SIZING, WILL REMAIN MACHINED IN THE AREA 0F INTEREST.
O THE ABILITY TO EXAMINE WITH THE USE OF AUTOMATED UT IS UNAFFECTED.
l O THE ABILITY TO EXAMINE-THE SAFE-END, THERMAL SLEEVE CREVICE AREA, AND SURROUNDING WELDS WILL BE UNAFFECTED.
THE PIPELOCK WILL ALLOW ACCEPTABLE EXAMINATION BY UT FOR DETECTION, SIZING, AND MONITORING OF IGSCC INDICATIONS.
