ENCLOSURE 1 NOTICE OF VIOLATION Carolina Power and Light Company Docket Nos. 50-325 and 50-324 Brunswick License Nos. DPR-71 and DPR-62 The following violations were identified during an inspection conducted on June 24-28, 1985.
The Severity Levels were assigned in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C).
1.
10 CFR 50, Appendix B, Criterion V, requires that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, and shall be accomplished in accordance with these instructions, procedures, and drawings.
Brunswick specification No. 248-107 requires that QC verifications shall be made to insure that catalogue components identified and called for on the design drawings have been used in the support.
Construction shall be responsible for insuring that erection activities are in compliance with the design drawings.
Procedure QCP-203 requires that QA/QC shall verify that all hardware, such as bolts, nuts, etc., is installed as shown on the design drawings. Missing hardware will be documented per procedure QCP-401.
Contrary to the above, activities affecting quality were not being accomplished in accordance with documented procedures and drawings in that a field inspection of 14 QC accepted pipe supports revealed two supports with deviations from the documented requirements. Furthermore, deficiencies in the anchor bolt installation were also identified. The supports and the anchor bolts are listed below:
a.
Unit 1 Service Water System Support No. ISW-142-PG409, Rev. A - Both the design drawing and the manufacturer's instruction showed a bolt connection for the two strut assemblies.
Studs were actually used in the installation.
Further, the studs were installed with double nuts on one side and a single nut on the other.
No locking device was found on the single nut side.
b.
Unit 2 Radwaste Drain System Support No. PS-7384, Rev. C - The l' - 3 1/2" and l' - 11/2" measured dimensions were incorrectly marked down on the as-built drawing in that these two dimensions should have been inter-changed.
c.
Unit 2 safety-related steel frame at elevation 50 foot - One anchor bolt in each of the two baseplates was improperly installed in that there was no bearing contact between the nuts and baseplates.
This is a Severity Level V violation (Supplement I).

design.
Brunswick Design Guide SDG-2, paragraph 7.1, requires that welds shown on L
design drawings shall be in accordance with AISC and AWS D1.1 codes unless otherwise noted.
Welds that are to be in accordance with AISC and ANSI B31.1 shall conform to weld detail and joint preparation requirements l-of AWS D1.1 code.
Contrary to the above, a field inspection of 14 QC accepted pipe supports revealed two supports with deviations from the documented requirements.
The two supports are identified below:
a.
Unit 2 Radwaste Drain System Support No. PS-3695, Rev. B - A 1/8" fillet l
weld was specified by the design drawing.
In accordance with the American Welding Society (AWS D1.1) code requirements, the minimum size of fillet weld should be 1/4".
l b.
Unit 2 Residual Heat Removal System Support No. 2E11-127-PG1002, i
Rev. A - A 1/4" fillet weld was specified by the design drawing. The column and the baseplate had a thickness of 1/2" and 1", respectively.
In accordance with the American Institute of Steel Construction (AISC) code requirements, the minimum size of fillet weld should be 5/16".
This is a Severity Level V violation (Supplement I) and applies to Unit 2 only.
Pursuant to 10 CFR 2.201, you are required to submit to this office within 30 days of the date of this Notice, a written statement or explanation in reply, including:
