ENCLOSURE I NOTICE OF VIOLATION Tennessee Valley Authority Browns Ferry Docket Nos. 50-259, 50-260, 296 License Nos.
DPR-33, DPR-52 and DPR-68 During the Nuclear Regulatory Coranission (NRC) inspection conducted on August 6-10,
- 1990, a violation of NRC requirements was identified.
In accordance with the "General Statement of Policy and Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C
( 1990), the violation is listed below:
10 CFR 50, Appendix B, Criterion IX, Control of Special Processes,
- requires, in part, that measures shall be established to assure that special processes, including welding...
are controlled and accomplished using qualified procedures in accordance with applicable codes...
ASME Boiler and Pressure Vessel Code Section IX, the applicable code for welding procedure qualification contains the following requirements:
A.
gW-200.2 states in part that the procedure qualification record (PgR) form shall list the actual variables used within the limits of a narrow range, rather than full range of the variables allowed.
B.
Where impact testing of materials to be welded is
- required, supplementary essential variable gW-403.6 is applicable, which specifies that for material thicknesses less than 5/8 inch the minimum thickness qualified is the thickness of the test coupon.
Contrary to the above:
(I)
PgR GT-SM11-0-3-C lists the full range of variables allowed for shielding gas flow, welding current and arc voltage rather than the actual variables used during the qualification welding.
(2)
P(R GT-SM11-0-3-C, an impact tested PgR states that the test plate thickness was 1-7/8" and the minimum thickness qualified was 3/16".
The minimum thickness limit for impact tested application of 5/8" as required by gW-403.6 was not listed.
This is a Severity Level IV violation (Supplement I).
