Davis Besse CRDM Nozzle Examination A February / March 2002 PROPRIET-ARY FRAMATOME ANP Automated ultrasonic examinations of 69 CRDM nozzles were performed from beneath the head using the ARAMIS inspection tool and a uCirc." blade probe.
Framatome ANP examination procedure 54-lSI-100-08, "Remote Ultrasonic Examination of Reactor Head Penetrations" was used to perform the examination. This procedure was revised by change authorizations #FRA 002 and #DB-02-012 and governs the remote automated contact ultrasonic examination of CRDM nozzles using the ACCUSONEXT automated data acquisition and analysis system.
The techniques utilized for this examination are intended for the detection and through-wall (depth) sizing of circumferential ID and OD initiating flaws in the nozzle base metal only. Forward scatter (TOFD), longitudinal-wave techniques are used. The examinations were conducted from the bore of the CRDM nozzles in the J-groove weld region of the nozzle.
The examinations performed with the blade probe consisted of scanning for circumferential and significant axial flaws within the nozzle wall. The tooling consisted of a blade containing a nominal 5 MHz, 50 degree TOFD transducer set. The circ. blade probe provides flaw detection (axial and circ. flaws) and sizing (non-axial flaws) information. For the forward scatter transducers, flaw detection is identified by loss of signal response either from the lateral wave or backwall responses as well as the presence of crack tip diffracted responses.
Prior to the examinations, demonstrations were performed using the EPRI/MRP samples removed from Oconee. This demonstration showed that circumferential as well as axial flaws could be detected with the circ. blade probe.
The ARAMIS tool was positioned beneath each nozzle examined with the Yt axis (axial) zeroed at the bottom of the nozzle with the positive direction extending up the nozzle. The Theta" axis was zeroed at the downhill side of the nozzle with the positive direction proceeding in the clockwise direction while looking down from the top of the nozzle. Following the initial examination, some nozzles had areas where the gap was too narrow to insert the probe. All of these exclusion areas were rescanned after the initial inspection by moving the lead screw support tube to open the gap for examination.
The examination with the blade probe identified flaw indications in six nozzles (1, 2, 3, 5, 47, and 58). Because almost all of the flaws detected on these nozzles were characterized as axial, only limted information was available with the circ.
blade probe. These axial flaws could have been characterized using axial blade probes, however, because there was a high probability that these nozzles would require repair, the drives for these nozzles were removed in order to perform additional UT examination using the Top-Down tool. The Top-Down tool contains 10 transducers and provides the ability to detect and characterize axial and circumferential flaws and also provides additional information in the nozzle 2

tube required for the repair activity. Images of the nozzles identified for repair are included in this report and identify the various landmarks required to implement the repair. These generally include the location of the head OD, the elevation of the proposed cut line, and the location of the top of the j-groove weld.
Automated ultrasonic examinations of six CRDM nozzles (1, 2, 3, 5, 47, and 58) were performed using the Top-Down inspection tool and Framatome ANP examination procedure 54-lSI-100-08. The techniques utilized for the examination are intended for the detection and through-wall (depth) sizing of axial and circumferential ID and OD initiating flaws in the nozzle base metal only.
Forward scatter, longitudinal-wave and backward scatter shear wave techniques are used. The examinations were conducted from the bore of the CRDM nozzles in the J-groove weld region of the nozzle.
The inspections consisted of scanning for axial and circumferential flaws within the nozzle. The tooling consisted of a transducer head that holds 10 individual search units. These search units were divided into two sets, one for the axial beam direction and one for the circumferential beam direction. The axial beam direction set of search units consisted of 5.0 MHz, longitudinal wave forward scatter time of flight search units with angles of 300 and 45°; backward scatter pulse echo, 2.25 MHz 600 shear wave search units; and a 5.0 MHz 00 search unit (see Appendix A for calibrations files and scan parameters). The circumferential beam direction set of search units consisted of 5.0 MHz, longitudinal wave forward scatter time of flight search units with angles of 450, 550, and 65°; backward scatter pulse echo, 2.25 MHz 600 shear wave search units; and a 5.0 MHz 0 search unit (see Appendix B for calibrations files and scan parameters).
The detection of flaw indications is based upon the expected responses for each search unit and technique. The 00 transducer provides weld position information and also provide positional information due to lack of backwall response in the region of the flaw. The forward scatter time of flight techniques provides flaw detection and sizing information. For the forward scatter transducers, flaw detection is identified by loss of signal response either from the lateral wave or backwall responses as well as detection of crack tip diffracted responses. The 600 shear wave transducer provides detection by means of corner trap responses between the flaw and nozzle surface and sizing with tip diffracted signals.
The top-down tool was positioned with the Z"axis (axial) zeroed at the top of the nozzle flange with the positive direction extending down the nozzle. The Theta" (rotational) axis was zeroed at the dowel pinhole in the flange with the positive direction inthe clockwise direction while looking down from the top of the nozzle.
The ultrasonic data is adjusted for individual transducer offsets in the transducer head to provide actual reflector location in the nozzle.

Davis Besse CRDM Nozzle Examination A February / March 2002 PIROPR1ETARY FRAMATOME ANP This report contains the data sheets from ultrasonic examination of the 6 CRDM nozzles that were identified as having flaws with the blade probe. Included in this report are the data sheets for the blade UT and the rotating UT from the Top-Down tool. Images of the UT data are also included to show the features identifying detected flaws.
The data was also reviewed for evidence of a leak path in the penetration bore with the blade and rotating UT techniques. Leak paths were detected in nozzles 1, 2, and 3 with blade and rotating UT. Images of the leak paths are included in this report.
Review of the attached data sheets for the circ. blade and Top-Down UT examinations will show that not all of the axial flaws identified with the circ. blade probe were confirmed with the rotating probe. In each case, axial flaws were identified with the circ. blade probe but could not be substantiated with the rotating UT. This is primarily due to the means required to identify an axial flaw when the beam is directed along the axis of the nozzle with the circ. blade probe.
Detection of an axial flaw with the circ. blade is made based on lack of signal amplitude and pattem of the signal loss observed in the C-scan. This loss of signal can either be due to interruption of the sound energy by an axial flaw in the beam path or by extemal factors affecting probe contact such as nozzle ovality or weld shrinkage.
The rotating UT also has conventional backward scatter transducers in both the axial and circumferential beam directions. These transducers rely on direct reflection from the flaw to provide detection. This is the opposite of the method used for the circ. blade probe and provides confirmation that a real flaw is detected. This is the reason that some of the flaw signals detected using the circ. blade probe were subsequently listed as non-relevant using the Top-Down tool. These axial flaw signals detected with the circ. blade probe could have also been dispositioned with the axial blade probes but, because they were likely candidates for repair, it was more efficient to use the rotating UT with the Top-Down tool for final disposition. Therefore the data from the Top-Down tool is considered the final result for each nozzle. Both data sheets are provided in this report for comparison.
A summary of the examination results is presented in the following table. The ultrasonic instrumentation calibration parameters are also included at the end of this report.

Davis Besse CRDM Nozzle Examination AFRAMATOME ANP February / March 2002 ROIRKIEIART This scan provided the Initial detection of an axial flaw in the nozzle wall using the circ. blade probe. Leak Path patterns are not observed in this image. The flaw is detected starting below the weld and extending up to the J-groove weld region of the nozzle. The rotating UT determined that this area did not contain any flaws. The indication was determined to be non-relevant caused by nozzle ovality interfering with probe contact.

Davis Besse CRDM Nozzle Examination February / March 2002 P i E9AR AFRAMATOCME ANP This scan provides more comprehensive characterization of the axial Indications detected using the circ. blade probe. This Image Is from one of the 60-deg. shear wave transducers with the beam directed circumferentially. All views with all transducers show the absence of signals that can be correlated with the blade UT results. Therefore the indication detected with blade probe is considered non-relevant.
