ENCLOSURE 1
NOTICE OF VIOLATION Tennessee Valley Authori.ty Browns Ferry Docket Nos.: 50-259, 50-260 and 50-296 License Nos.:
DRP-33, DRP-52 and DRP-68 During an NRC inspection conducted on July 12 - 16,
- 1993, two violations of NRC requirements were identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," the violations are listed below:
A.
10 CFR 50, Appendix B,, Criterion XVI, requires that measures shall be established to assure that conditions adverse to quality such as noncon-formances are promptly identified and corrected.
Criterion XVI also requires that the measures shall assure that the cause of the condition is determined and corrective actions taken preclude repetition.
TVA's letter of response, dated February 10, 1993, to NRC Notice of Violation No. 50-259,260,296/92-43-01 stated that to prevent recurrence of a welding program discrepancy, "GE has initiated the development and use of a Design Change Notice (DCN) requirements checklist.
This checklist identifies the requirements in the DCN and provides a tracking method of accounting for completion of each requirement.
" In addition, the complete checklist is then reviewed and is approved by the Project Manager and GE's gC group.
The effective date for implementing the DCN checklist form was January 5, 1993.
Contrary to the above, on July 15, 1993, discussions with GE's gC personnel and review of DCN W-18096A revealed that GE's DCN checklist is presently not being used by GE for DCNs involving welding and weld repairs in the plant.
In addition, GE had not revised their welding manual or administrative procedures to implement this commitment for preventing recurrence of the nonconforming condition.
This is a Severity Level IV violation (Supplement 1).
B.
10 CFR 50, Appendix B, Criteria III, Design Control, requires that design changes, including field changes, shall be subject to design control measures commensurate with those applied to the original design and be approved by the organization that performed the original design unless the applicant designates another responsible organization.
TVA Nuclear Engineering Procedure, NEP-3.1, calculations, page 1 of 1 of, requires that design inputs, including information such as
- loads, temperatures, and pressure originated within engineering or supplied by vendors, and codes, standards, regulatory requirements, and FSAR commitments, shall be current and correctly selected, referenced and applied.
