Fitzpatrick Nuclear Power Plant Lycoming, New York 13903 Dear Mr. Sancic We have examined the two radiographs you sent: the original and the repair shot of the 22" OD manifoid to end cap weld. Using our Image enhancement techniques and concentrating our attention on the region Indicated by the sketch that you included, we found a linear Indication, approximately 3/4" long, in both radiographs. The Indication Is parallel to the weld direction. I have enclosed f Ive pictures to support our observation. These pictures are not as good as the pictures we can get on our monitor, bi* they do show the Indication. The first picture shows most of the weld and is included to The area of the weld that provide a reference for the rest of the pictures. The next two the other pictures contain is indicated on this fIrst picture. pictures (2 and 3) are the digitized Images of the original and repair shots. Pictures 4 and 5 are the enhancements of 2 and 3. Notice that the titles on pictures 2 tniough 5 are on the bottcm of the image. To help orlent the viewer I have marked where the 2 and 3 markers on the pipe would be found. While the exact On pictures 4 and 5 the linear indication has been marked. shape is dif ficult to see, the general slope is the same for both. Also I have marked a prc<ninent segment of the Indication on both with an arrow. This Indication is in the same location in both Irrages. We are returning the two radiographs at th9 same time but as a seperate package. If you should have any questions please do not hesitate to call me, e or Mr. Scott D. Fouse, who is the Technical Director for Aptech Imaging, or I have enclosed Dr. Geof frey R. Egan, who assisted with the interpretation. resumes of Mr. Fouse and Dr. Egan.
