Examination Summary
The ultrasonic examination of weld V-3-C resulted in no recorded indications that exceed the allowable standards of IWB-3500, ASME SectionXI, 1986 Edition, No Addenda.
The ASME Section XI required examination volume was examined with the GERIS 2000 System from the RPV inside surface utilizingProcedure No. GE-UT-700, Rev. 2. This examination was limited due to the feedwater sparger and the core spray downcomer. Areas thatcould not be examined using the GERIS 2000 and accessible from the outside surface were examined by the manual technique utilizingProcedure No. GE-UT-300, Rev. 6, FRR-004. The total examination coverage was calculated to be 70%.
The GERIS 2000 utilizes an array of search units arranged to effectively examine the weld and adjacent base material parallel and perpendicularto the weld axis in two directions. The transducer package consisted of 00 longitudinal, 45° and 600 shear wave, and 70° refracted longitudinal(RL) wave search units,
The GERIS 2000 recorded indications with the 0° weld metal scans and the 450 and 60° shear wave scans that were evaluated and found to beacceptable per the referencing Code section.
The manual technique utilized 0* longitudinal, 450 and 60° shear wave search units both parallel and perpendicular to the weld axis in twodirections to effectively examine the weld and adjacent base material.
The manual examination recorded one (1) geometric indication with the 0* search unit due to a core spray sparger support bracket.
Fabrication records and previous examination results were reviewed prior to the completion of this examination summary.
