This refers to the inspection conducted by Messrs. Hayes and Rohrbacher of this office on January 11 - 12, 1972, of construction activities at the Davis-Besse site authorized by AEC Construction Permit No. CPPR-80 and to the discussion of our findings at the conclusion of the inspection with Messrs. Wadsworth, Eichenauer, Maring, and Wilcox of your staff.
Areas examined during the inspection included revised procedures for placement of pumped concrete, concrete sample cylinder strength test resulto, containment vessel fabrication, concrete placement practices, receipt and storage of component heat exchangers and waste gas decay tanks, and procedures for installing Class I piping. Within these areas, the inspection consisted of selective examination of procedures and representative records, interviews with plant personnel, and observations by the inspectors.
The inspectors also e===4nad actions you have taken with respect to the items identified in your letter of December 2, 1971, relating to matters previously brought to your attention. We have no further questions on these matters.
No items of noncompliance with AEC requirements were identified within the areas ow= mined during this inspection.
With regard to questions raised during this inspection, we understand that all concrete production at the site was stopped pending resolu-tion of a possible problem related to concrete having low compressive strength based on the results of seven-day break tests. We also I
