APPENDIX A NOTICE OF VIOLATION Tennessee Valley Authority License No. CPPR-72 Based on the results of the NRC inspection conducted on December 11, 1978, and December 13-15, 1978, it appears that certain of your activities were not conducted in full compliance with NRC requirements as indicated below. These items have been categorized as described in our correspondence to you dated December 31, 1974.
A.
Criterion IX of Appendix B to 10 CFR 50, as implemented by the FSAR, paragraph 17.1A.9, requires in part, " Measures shall be established to assure that special processes, including... nondestructive testing, are controlled and accomplished...in accordance with applicable codes,..".
The ASME Boiler and Pressure Vessel Code, 1974 edition plus addenda through the summer of 1975, Appendix I, paragraph I-4230 requires daily UT instrument calibrations for amplitude linearity and amplitude control linearity for UT of ferritic pressure vessels 2 -inches and greater in thickness.
Contrary to the above requirements, the following was observed:
on December 13, 1978, during inspection of the UT procedure applicable to ferritic pressure vessels 2k-inches and greater in thickness (UT-2, Rev. 11), the inspector noted that the requirement for daily linearity calibrations was not delineated in the procedure.
This is an infraction.
B.
Criterion V of Appendix B to 10 CFR 50, as implemented by the FSAR, paragraph 17.1A.9, requires in part, " Activities affecting quality shall be prescribed by documented instructions, procedures...and shall be accomplished in accordance with these instructions, procedures.
Ultrasonic testers shall..have their proper internal alignment and calibration verified within 90 days of use."
Contrary to the above requirements, the following was observed:
on December 11, 1978, the inspector observed UT tester serial no. 130-063-D being used for testing of pressurizer nozzle to vessel welds RCW-15,18, and 20. On December 13, 1978, during review of calibration certification for this UT tester, the insepctor noted that the most recent calibration was performed on September 6,1978.
This is an infraction.
