Radiography of Main and Auxiliary Feedwater Lines This inspection was performed on account of the NRC's request that the licensee radiograph certain weldments in the emergency feedwater (EFW) and main feedwater (FW) lines of steam generator B in order to verify weld integrity. The,icensee and RII agreed to radiograph a total of sixteen welds which were as follows: (1) each of the four welds in one feedwater and one emergency feedwater riser; both located at or/near the ring-header tee, (2) the three welds in the main feedwater ring-header tee and, the last weld on the main feedwater line prior to the first restraint off the main feedwater ring-header, (3) the last veld in the vertical leg on the emergency feed line to the emergency ring-header and, the two subsequent 9;) .y.

According to Table 136.5.1 of this code, there was no requirement for surface or volumetric examination to be performed on these lines. Erection fabri-cation drawings did specify magnetic particle inspection (MT) on all weldments and radiography on the 14 inch diameter tee of the ring-header of the FW line. Radiography on the designated welds was being performed by Branch Radiographic Laboratories Inc. (BRLI) in accordance with RT pro-cedure ISI-300 R/8. Results of radiographic review disclosed no evidence of service related indications on any of the welds checked. Fabrication related indications were noted in three main feedwater line welds, two in the three inch riser and one in a 14 inch din eter shop fabricated weld.
The licensee has agreed to examine these welds again (monitor) during two subsequent ISI inspectionr and the inspector identified this matter as inspector followup item (79-25-01).
