The following conditions were identified:
1.
Bechtel Work Plan Procedure/guality Control Instruction No. 66, Rev. 2, "Post-tensioning Trumplate and Sheathing Installation and Inspection," provides for accomplishing work in accordance with specified procedures, instructions, and drawings, as required by.10 CFR 50; Appendix B, Criterion V, tive PSAR Section 17.1A.5, and the Palo Verde Nuclear.

Contrary to these requirements, the following examples of non-conforming work were observed:
A.
B.
C.
D.
Vertical and horizontal tendon sheaths installed for placement No.
1C109 were wire tied at intervals greater than the maximum interval of 3'6", specified in WPP/gCI 66.
Six trumplate extensions were found to be unwired at their ends contrary to the requirements of WPP/gCI 66.
Two vertical sheaths (the 17th and 19th clockwise from the center of the equipment hatch) were found to be out of align-ment by 2" in 10 feet, whereas drawing 13-C-ZCS-175, Rev.
2, DCN 1 specifies-a maximum misalignment of 3/4" in 10 feet.,
Horizontal sheaths above the equipment hatch were found to be within 1-1/2" of each other, whereas drawing 13-C-ZCS-175, Rev. 2, DCN 1 specifies a minimum clearance of 3" in this area.

Contrary to these requirements, mandatory inspection hold points for the drilling of sheathing vent holes, installation of vent piping, wiring of sheathing, and positioning of sheathing were performed in a random sampling manner instead of the full coverage, required by WPP/gCI 66.
This is an infraction.

No quality records,
- however, were maintained for even the sampling inspections, which would identify items inspected, and the date and results of inspections.
B.
Records for inspections of trumplate installation for concrete placement 1C108 were not signed off by guality Control Engineers prior to the placement of concrete.
This is a deficiency.
