Containment (Structural Concrete I) - Observation of Work and Work Activities, Units A-1, A-2 and B-1 Prior to the start of the A-1 placement, the following site procedures were examined:
C. F. Braun and Company Specification 300-01, " Concrete TVA STRIDE, " Revision 5; Control Instruction C-201, Concrete Placement, Revision 4; C-207 Reinforcement Steel Placement, Revision 1; Construc-tion Engineering Procedure 9.02, Concrete Placement Control, Revision 2; and C-401, RIS&PM Concrete Materials Cadweld Shines.
In addition, the condition of the hoppers, test equipment, pumps, forms and other equipment, pumps, was examined and found acceptable.
Ample crews were available for the placement and were equipped with the proper vibrators and chutes.
1be concrete mixing, transportation, and holding time prior to placement was within specificatien.
The inspector observed that during placement the free fall of the concrete was approximately ten feet. The licensee was cautioned that although this was within specification close observation is needed by the TVA QC personnel to insure that it is not exceeded since they are already on the high side of the limit.
In addition the vibrator crews were prone to leave the vibrators in one spot the maximum allowable time.
The licensee was cautioned that this required close surveillance by QC personnel to insure that the vibrator crews do not exceed time limitations.
No items of noncompliance or deviations were identified.
6.
Licensee Identified Items Prior to this inspection, the licensee identified the following items under the terms of 10 CFR 50.55(e):
(0 pen) Item 518/519/78-10-01 - Altered Cadwelds A TVA QC inspector noted that filler metal other than Cadweld filter metal was used on a Cadweld splice.
