Radiography of Feedwater Welds Based on the cracking recently occurring at the feedwater nozzles in PWR plants, there is a question as to whether or not BWR plants might have the same type of preblem. Discus-
_
sions between CECO and the RIII on this subject resulted in a commitment to radiograph the safe end to nozzle and safe i
end to pipe welds on all four feedwater nozzles during the
'
current refueling outage on Unit 2.
One weld was radiographed, safe end to pipe (weld N4D) with the original thermal sleeve in place. The purpose of this was to determine that radiography is feasible in the event radiography of the same welds on other units are required.
The remainder of the welds were radiographed with the thermal
sleeves removed, but still prior to removal of the internal cladding in the area of nozzle.
After removing the cladding and with the new thermal sleeve
installed, a nozzle to safe end weld was radiographed (N4C).
'
This determi;.ed that such a technique was not feasible by radiography for future inspections with the new type thermal sleeve installed. Different speeds of film were used to try and accomplish an acceptable radiograph with approximately 100 curies of IR192.
The leakage land grooves of the new thermal sleeve are approx-imately 1-1/4" apart, 1/4" wide, with one end of the weld in the area of interest. The grooves have abrupt changes and make clongated indications.
Penetrameter essential holes and the outline of the penetrameters were not visible. Definition, latitude, and sensitivity were very poor. All the above are unacceptable to ASME Section III, 1977 Edition, Summer 1979
,
Addenda and CECO procedure, Radiographic Examination, NDT-A, Revision 7, December 6, 1978.
CONAM inspection performed the radiography.
The radiography was also performed in accordance with IE Bulletin No. 79-13 titled " Cracking in Feedwater System Piping", except for the width of the coverage on the adjacent pipewelds. The material thickness is approximately one inch thick and the radiographic films were 4-1/2" wide. The Bul-j letin stated that there would be a distance equal to at least two wall thicknesses on each side of the weld. The radio-graphic films used on the safe end to nozzle welds were 7" wide.
The inspector reviewed the radiographs of the following welds:
