(Section II.B.2.b.(6))

b.

Approximately one-third of the total of A490 bolts. tested by the NRC CAT were found to be below the pretension required by AISC.

Installation and inspection requirements had not been translated into appropriate procedures for high strength bolted connections in structural steel and nuclear steam supply system joints which require pretension in the bolts.

(Section V.B.1.b)

During the inspection, concrete expansion anchors were found which c.

did not meet the required bolt diameter embedment depth.

It could not be shown that embedment length requirements for concrete expansion anchors as specified in the concrete expansion anchor qualification report had been translated into appropriate installation and inspection procedures.
