GE NuclearEnergy

. Profect Summary During the time period from 1 April through 3 April 1998, General Electric inspection Services conducted ultrasonic examinations of Recirculation inlet Riser welds at Vermont Yankee, Unit 1.

The scope of the examinations included welds RS-1, RS-2 and RS-3 on Recirculation Inlet Risers N2A through N2K. The ultrasonic examinations were performed at the request of Vermont Yankee.

This report contains specific details regarding the performance and results of the examinations.

Eauloment Smart 2000 Acquisition System The Smarf 2000 data acquisition system was utilized for this examination. The Smart 2000 is 1 an eiglit channel multiplexed, digital system. The system digitizes the entire RF wave form at the rate of up to 80 MH:. The entire A-scan is digitized and archived to optical disk for off-line analysis review and comparison of subsequent examinations. l JPR-2000 Delivery System The JPR-2000 is installed on the component using a long pole and an underwater camera to aid in the proper placement of the scanner. The device attaches to the vertical piping member of the inlet Riser Assembly. The search units are positioned the appropriate side of s the weld joint and are then manipulated in a rectangular raster scan pattern about the entire circumference of the weld. This scanning motion provides volumetric coverage of the weld and HAZ on both sides of the weld.

Report 1HQXE, Rev. 0 1998 Wrmont Yankee Recittulation Inbet Riser Examination

O GE Nuclear Energy Smart 2000 Data Analysis Workstation The Smart 2000 Workstation is employed for the evaluation of ultrasonic data. The data is displayed with any combination of time (or amplitude)in A-scan, B-scan and C-scan views.

The color palette for data display and analysis purposes is adjustable. Preset color palettes can be used for amplitude evaluation, or adjustments can be made to enhance the B or C-scan display. Adjustable gates can be altered in either time or amplitude to re-display the C-scan image allowing the analyst to accentuate and focus on an area of concern.

Examination Methodoloav The examinations employ two 60* shear wave search units which are offset circumferentially by 180*. Scanning is performed from one side of the weld. The search units are positioned the appropriate side of the weld joint and are then manipulated in a rectangular raster scan pattern about the entire circumference of the weld. The ultrasound is directed to examine the volume of interest as depicted below:

1 ID Examination Results The examinations resulted with the detection of four flaws. These flaws are confined to the Thermal Sleeve-to-Elbow configuration (designated as Weld RS-1) of the riser inlet riser assemblies N28, N2C, N2H and N2K. The locations of the detected flaws (as seen looking in the direction of flow) along with their ultrasonic images, are illustrated below:
