TXX-2866 Page 2 Response to NRC Inspec tion Report 78-11 NOTICE OF VIOLATION Based on results of the NRC inspection conducted on June 20-23, 1978, it appears that certain of your activities were not conducted in full compliance with Appendix B to 10 CFR 50 as indicated below:

Fai'ure to Follow Piping Installation Procedures Criterion V of Appendix B requires that established instructions, procedures, or drawings be followed for all activities affecting quality.

Brown and Root Instruction 35-1195-PCI-001, " Pipe Department Cleanliness Control Guidelines", requires that each pipe spool, after being welded to previously comp'-ted niping runs, be examined by a pipe fitter foreman for cleariliness, capped, taped with red tape and tagged.

Contrary to the above:

The inspector observed on June 21 and June 22, 1978, that the i

unwelded ends of four pipe spools in the lower two headers of the

" containment spray system were capped but not taped or tagged as required.

This is an infraction.

Corrective Steps Which Have Been Taken and Results Achieved:

Beginning on June 26, 1978, a complete review of all pipe spools, valves and vessels in the field was initiated by Quality Control to ascertain compliance with the requirements of PCI-001. Items not protected and tagged as required were corrected by responsible craft personnel.

Results of the Quality Control efforts and a formal QA surveillance conducted on July 20, 1978 indicated the need for stronger controls on the part of construction management. This was initiated on July 21, and completed on July 25, 1978. Informal surveillance of selected areas on July 26, 1978, indicate that the management efforts have been effective and that spools, valves, and vessels are now being maintained in a manner consistent with the project requirements.

, Page 3 Response to NRC Inspection Report 78-11 Corrective Steps Which Have Been or Will Be Taken to Avoid Further Noncompliance All QC inspection personnel and pipe department foremen and general foremen have been administered detailed instruction as to the require-ments of pCI-001.

Additiot. ally, pipe department foremen were directed to instruct all pipe department craftspeople in their respective areas as to the requirements of PCI-001.

Effective July 25, 1978, formal QA surveillance will be performed on a minimum monthly frequency to verify that the established " Cleanliness Control" requirements are being maintained. Appropriate management ac-tion will be taken as necessary to maintain compliance with the project requirements.

Date of Full Compliance Corrective action was initiated immediately following the inspection and full compliance was achieved on July 25, 1978.
