e ATTACHMENT I RESPONSE TO ANONYMOUS ALLEGATION Anonymous Allegation "a circumferenetial crack about 10 inches long exists in the valve body of the."B" recirculation system pump suction valve. The alleged crack in the valve was noted by an individual while leaving the inside of the recirculation pipe following the removal of a sealing diaphram which had been used as a' seal for Jrgon purging of the pipe."
Response
Visual inspectione of the inside diameter of this valve were perfo=_ec an June 14, 1984 for the alleged crack. No such crack was found. The only thing that could possibly be what the alleger saw was an acceptable surface
. irregularity, not a crack, where the factory machined the area of the weld between the seat ring and valve body.
Further, there were several documented quality control inspections on the inside ' diameter of this valve during the installation with satisfactory results and no evidence of there having been a crack in the valve body.
The_ available Quality Control and Welding Engineers were questioned regarding the alleger's indication "his concerns were identified to others, including a QC representative. A visual inspection was perfonned and no corrective action was taken, and the valve was closed up".
There
~
was #ho recollection of such a conversation on the part of the Quality g
Control personnel or welding engineers.
