Appendix A NOTICE OF VIOLATION Commonwealth Edison Company Docket No. 50-456 Docket No. 50-457 Based on the inspection conducted on September 8, 12, 13 anc 14, 1978, it appears that certain of your activities were not condorted in full compliance with NRC requirements as noted below. These 1:2ms'are infractions.

A.

10 CFR 50, Appendix B, Criterion XVI requires in part, that condi-tions adverse to quality such as failures, deficiencies, devia-tions, defective material and nonconformances be promptly identified and corrected, and further, that the cause of the condition be determined and corrective action taken to preclude repetition as well as documenting and reporting the condition to 7

approprirte levels of management.

Commonwealth Edison Company, QA Manual, Quality Requirement 16.0 states in part, that "A corrective action system will be uced to assure such items as failures, malfunctions, deficiencies, deviations, defective material and equipment and nonconformances which are adverse to quality are promptly identified and corrected".

Contrary to the above, during the period c' September 19, 1977.hrough October.17, 1977, the central concrete mixer did not meet the uniformity test requirements of ASTM C-94, and this condition was not properly identified nor corrected. Specifically, the central batch plant mixer was permitted to continue production of safety-related concrete material, and approximately 27 placements with a total of 4,141 cubic yards of concrete were made even though the central mixer was known to be unsatis-factory according to the uniformity requirements.

B.

10 CFR 50, Appendix B, Criterion X requires in part, that a program for inspection of activities affecting quality be established and executed to verify conformance with documented instructions and procedures.

Commonwealth Edison Company, QA Manual, Section 2.2 states, in part, that, " Commonwealth Edison commits to comply...wish the Regulatory position of the following Regulatory Guides...; 1.94, Rev.

1...".

Regulatory Guide 1,94, Rev. 1 in turn commits Commonwealth Edison to ANSI N45.2.5-1974.

1 2-Appendix A ANSI N45.2.5-1974 requires mixer uniformity tears to be performed

. initially and every six months thereaf ter, in accordance with ASTM-C-94.

Contrary to the above, inspection requirements were not executed to verify conformance with documented instructions, in that, truck mixer uniformity testing was not accomplished at the six month

' frequency prescribed by ASNI N45.2.5-1974 Table B.

Truck mixer uniformity testing was last performed on September 20, 1977, and during this inspection, trucks were used as mixers on the containment building dome pour. Sargent and Lundy specifications allow the addition of water to truck mixers at the point of dis-charge, provided a minimum of 35 additional revolutions of the truck mixer at mixing speed are performed. Trucks performing this service are acting as mixers, and therefore, must satisfy mixer uniformity requirements..

No respones is required for this item since actions were initiated during the inspection to correct this matter in a timely manner and to prevent recurrence.
