You will notice from this correspondence that concern had been expressed regarding assurance that the proper grade of Incolay was used in the high temperature portions of the steam generators and their support structures.

From our review of inspection reports dating between tiarch 6,1970 and August 13, 1970, we concluded that there is reasonable assurance that the proper grades of Incoloy 800 were used in the Fort St. Vrain reactor.
