Mr. W. C. Seidle, Chief Reactor Construction and Engineering Support Branch U. S. Nuclear Regulatory Commission Office of Inspection & Enforcement 611 Ryan Plaza Dr. , Suite 1000 Docket Nos. 50-445/Rpt. 78-13 Arlington, Texas 76011 50-446/Rpt. 78-13 COMANCHE PEAK STEAM ELECTRIC STATION 1981-83 2300 MW INSTALLATION RESPONSE TO NRC INSPECTION REPORT NO. 78-13 DOCKET NOS. 50-445 & 50-446 FILE N0. 10130

Dear Mr. Seidle:

We have reviewed the report on the inspection conducted by Mr.

R. G. Taylor (August 1-31,1978) of the activities authorized by NRC Construction Permit Nos. CPPR-126 and 127 for the Comanche Peak facility. We have responded to the findings listed in Appendix A of your " Inspection Report" dated September 19, 1978.

To aid in the understanding of our response, we have repeated the requirement and your finding, followed on the same page by our corrective action.

We believe the attached information to be responsive to the Inspector's findings. If you have any questions, please advise.

Very truly yours,

4 TXX-2895 Page 2 Response to NRC Inspection Report 78-13 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 compliance with Appendix B to 10 CFR 50 as indicated below:

Failure to Follow Concrete Testing Procedures _

l Criterion V of Appendix B requires that established instructions, procedures, or drawings be followed for all activities affecting j quality.

i' Texas Utilities Generating Company Procedure QI-QP-11.1-10, Revision i 0, " Sampling Fresh Concrete," paragraph 3.1.2 requires that samples l be taken at two or more intervals during the discharge of the middle l portion of the batch.

1 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 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, practice when taking samples where cylinder strength tests are not a requirement.

This is an infraction.

Corrective Steps Which Have Been Taken and Result', Achieved:

Immediately following identification of the nont 7pliance, the Laboratory Field Coordinator verbally informed all field ra onnel of the correct sampling techniques for obtaining ' M-load accep'.ance test samples.

Additional formal discussions wet .,nducted with all personnel by the Test Laboratory and Produ.t Assurance Supervisor on August 31, 1978.

Corrective Steps Which Have Been or Will Be Taken to Avoid Further Noncompliance At the time this noncompliance was observed, all laboratory personnel were in the process of being retrained and recertified. This program, as established, results in observation of technique as well as written

or oral verification of a technician's knowledge of procedural require-l ments. Certification is then accomplished to procedures applicable

TXX-2895 Page 3 Response to NRC Inspection Report 78-13 i

l to the work activities for the various technician grades .that have l been established.

To assure the effectiveness of the training and certification program, monthly surveillances are planned of the testing activities until an adequate confidence level is established, then periodically to maintain this confidence level.

Date of Full Compliance Corrective action was initiated immediately following the NRC inspection and was fully implemented on August 31, 1978. Training of all personnel i was completed by October 17, 1978. The surveillance program will be implemented no later than October 31, 1978.
