SUSQUEHANNA STEAM ELECTRIC STATION RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION ON PROPOSED RELIEF REQUEST NO. 3RR-18 TO THE THIRD 10-YEAR INSERVICE INSPECTION PROGRAM FOR SUSQUEHANNA SES UNIT 2 PLA-6810 Docket No. 50-388

The purpose of this letter is to formally document the response to the NRC's Request for Additional Information (RAI) on PPL Susquehanna, LLC's (PPL) proposed Relief Request No. 3RR-18. The RAI was received in an email on January 5, 2012. A phone call was held on January 5, 2012 between NRC Staff and PPL in which the NRC Staff requested additional information. The response to the RAI and additional information was provided to the NRC Staff in an email dated January 10, 2012.

NRCRAI:

Provide a complete description of the subject weld (inspection category and item no.), the materials of construction, and its location in the system. .

PPL Response:

The AF weld is classified as an AS:ME Section XI Category/Item B-AIB1.30 weld. One third of this weld is volumetrically examined every inspection period. This weld connects Shell Course 5 (external reactor vessel) to the Shell Closure Flange. The weld is located at elevation 791', 115" (59'-7 19/32" from vessel zero). PerPPL Susquehanna FSAR, Rev 62, Table 5.2-4, the Shell Closure Flange is a Forge Ring made ofLow Alloy Steel, SFA-508, Cl.2. The weld also consists oflow alloy steel, SFA-5.5.

Per conversations between the NRC and PPL held on Thursday, January 5, 2012 an additional request for a copy of the most recent volumetric examination record of the AF weld from the U2-15RIO was made. The examination is contained in Attachment 5.
