B-G-1 Five RPV studs were examined by UT and MT techniques. Two RPV studs received an MT examination but not a UT examination as time did not permit.

B-J Three welds had UT indications which were evaluated as root geometry.

One weld had a UT indication which was evaluated as counter bore geometry.

Two welds exhibited UT beam redirection due to dendritic weld structure.

Two welds had UT indications which were evaluated as counter bore geometry.

One weld had four UT indications which were evaluated as root geometry and one indication which was evaluated as ID geometry.

One weld had two UT indications which were evaluated as root geometry and one indication which was evaluated as counter bore geometry.

One weld had a UT indication of geometric origin based on transducer position and the ID/OD profile.

.No corrective measures were required as a result of'UT examinations. All recorded indications were. evaluated an'd determined to.be related to geometry or weld: metal' structure.-

A surface examination (MT) exhibited.an unacceptable linear indication which appeared to be-a non-relevant condition ofL undercut orcoverlap. .Further surface.. conditioning verified the; condition and yielded an acceptablefre-examination.
