APPENDIX A NOTICE OF VIOLATION Tennessee Valley Authority Docket No. 50-260 Browns Ferry 2 License No. DPR-52 As a result of the investigation conducted on October 27-31, 1980, and in accor-dance with the Interim Enforcement Policy, 45 FR 66754 (October 7, 1980), the following violations were identified.
A.
10 CFR 50, Appendix B, Criterion V and Topical Report TVA-TR75-01, paragraph 17.2.5 requires " activities affecting quality shall be prescribed by documented instruction, procedures...and shall be accomplished in accordance with those instructions, procedures...."
Instructions documented in Part III, Section 7.2 of the Operational Quality Assurance Manual and in Standard Practice BF 10.3 require that a failure to comply with applicable codes or specifications be considered a noncompliance item to be reported on form BF-20 and forwarded to the QA Supervisor for disposition.
Contrary to the above, on October 22, 1980, a failure to comply with code and specification requirements occurred which was not documented or submitted for proper disposition.
Welding was performed on High Pressure Coolant Injection System weld FW-9 by an unqualified welder, a violation of the applicable code (USAS B31.1.0) and specification (N73M2) requirements.
Supervision was aware of this, but failed to document the noncompliance on form BF-20 and submit it for proper disposition.
This is a Severity Level V Violation (Supplement. li.E).
B.
10 CFR 50, Appendix B, Criterion V and Topical Report TVA-TR75-01, paragraph 17.2.5, require " activities affecting quality shall be prescribed by documented instructions, procedures...and shall be accomplished in accordance with those instructions, procedures...". Instructions in TVA Process Specification 1.M.3.1(f) (a part of TVA Specification N73M2) require that "after welding materials have been removed from containers or packages they shall be identifiable by type until consumed."
Contrary to the above, On October 30, 1980, all welding materials were not maintained identifiable by type in that two unidentified lengths of bare wire were mixed with similar appearing, but properly identified, ER-308 (stainless steel) weld wire in the issue station. The unidentified wires appeared to be carbon steel.
In addition, instructions were not provided for control of unused bare filler wire for Gas Tungsten Arc Welding and uncontrolled welding material was present on the torus.
This is a Severity Level V Violation (Supplement II.E).

Appendix A License No. DPR-52 Notice of Violation C.
10 CFR 50.55a(d) and the FSAR require that High Pressure Coolant Injection (HPCI) System piping meet the requirements of USAS B31.1.0 (1967). Based on Figure 127.4.4.C of USAS B31.1.0 (1967), HPCI System piping bypass line fillet (socket) welds FW-1 through FW-9 (documented in TVA Browns Ferry Work Package 9883) require fillets ranging in size from about 1/4 to 5/16-inch.
Contrary to the above, on October 31, 1980, welds FW-1 through FW-9 were undersize an e stimated 1/16 to 1/8-inch.
This is a Severity Level V Violation (Supplement II.E).
