3.-
Steam Dryer Inspection
.
.
The Upper. Steam Dryer Assembly was submerged in the equipment storage pool
'
l'
and was inspected visually by using an underwater light to illuminate the weld seams.
i a
These conditions would have made it possible to identify open weld metal separations with reasonable definition, however,- tight cracks in the weld metal would not be visible by the above inspection techniques.
i
'
The inspection performed under the above conditions by both the licensee and the inspectors did not reveal any weld metal separations.
4.
Feedwater Spargers Inspection
,
i
An inspection of the feedwater spargers had been performed by the
licensee prior to May 2, 1973. The inspection was made using a Diamond Power Company underwater TV camera and recording the results on video q
tape.
The underwater camera is equipped with two heads. One head is straight and views from the bottom side of the camera.
The other head views an area 90* from the straight head. This permits a view of the top inside corner, the top outside corner and the bottom inside corner of the box section of the sparger and the top periphery of the thermal sleeve weld.
The video tapes were reviewed by the inspector with a narration by the engineer in charge of the inspection.
It was apparent that the scanning i
had been performed at a slow rate and was constantly adjusted for focus to provide good definition. The tapes had sufficient resolution to define grinding marks, scratches, metal ' stamping and small particles of adhering dirt.
Based on the preceeding description of inspection conditions, no cracks were identified.
