Pesults of the inspection indicate that 19 pieces of high carbon steel were found in Unit 2 and none in Unit 1.
Tests indicate this material was not the specified A36 steel but, resembled SAE 1547..As a r_esult of this investigation, the fabricator has included high carbon steel in his color coding system to prevent recurrence. The defective cap plates have been replaced with the specified A36 material. This item is con-sidered closed.
