, APPENDIX A NOTICE OF VIOLATION Duquesne Light Company Docket No. 50-412 Beaver Valley, Unit 2 License No. CPPR-105 As a result of the inspection conducted on June 9 - 20, 1986, and in accordance with the NRC Enforcement Policy (10 CFR 2, Appendix C), the following viola-tions were identified:

A. 10 CFR 50.55a requires that structures shall be fabricated and inspected in accordance with the requirements of the applicable edition of the ASME Boiler and Pressure Vessel Code.

Section III, Subsection NF of the 1974 Edition of the ASME Boiler and Pres-sure Vessel Code governs the fabrication and inspection of safety related component supports for Beaver Valley Unit 2.

The Specification for Fabrication of Steam Generator, 2 BVS-43, implements the requirements of Subsection NF and requires that structural shapes with thicknesses between 3/8 and 2 inches be conditioned by the removal of injur-ious linear imperfections which exceed 1/16 inch in depth.

Contrary to the above, an NRC visual examination during June 9-20, 1986 l disclosed that a previously inspected and accepted lower support assembly for Steam Generator C had a 6 inch linear indication which was 3/16 inch deep, that had not been recorded or dispostioned as required by Specification 2BVS-43.

This is a Severity Level IV violation (Supplement II).

B. 10 CFR 50, Appendix B, Criterion V requires that activities affecting quality be conducted in accordance with established procedures and draw-ings.

The NES Specification for the Fabrication and Inspection of the Neutron Absorber Spent Fuel Storage Racks, document 80A7780 Revision 0, states that any cracks or linear indications greater than 1/16 inch shall be considered unacceptable and drawing 80E7653 denotes the critical welds that require penetrant examinations.

Contrary to the above, an NRC liquid penetrant examination of two critical welds on Bundle #16 revealed unacceptable linear indications that had not been previously recorded or dispostioned as required by the specifications.

This is a Severity level IV violation. (Supplement II).
