50-445/78-13 50-446/78 13 Appendix A NOTICE OF VIOLATION Based on the results of an NRC inspection conducted on August 30, 1978, it appears that certain of your activities were not conducted in full com-pliance with Appendix B to 10 CFR 50 as indicated below:
Failure to Follow Concrete Testing Procedures Criterion V of Appendix B requires that established instructions, procedures, or drawings be followed for all activities affecting quality.
Texas Utilities Generating Company Procedure QI-QP-11.1-10, Revision 0, " Sampling Fresh Concrete," paragraph 3.1.2 requires that samples be taken at two or more intervals during the discharge of the middle portion of the batch.
Contrary to the above:
The IE inspector observed on the above date, during placement of concrete in a reactor building interior wall, that a concrete I
laboratory technician took a single sample rather than at two or more intervals during the discharge of the middle portion of the batch.
Discussions with the technician and the laboratory super-visor confirmed that this was the standard, but undocumented, I
practice when taking samples where cylinder strength tests are not l
a requirement.
This is an infraction.
