Safety-Related Cable Tray Supports
- a.
Review of Procedures The NRC.inspecter reviewed the following documents to assure that adequate controls ~have been established relative to welding of
.
safety-related cable tray support modifications:

Instruction QI-QP-2.1-14, " Qualification of Electrical
Raceway / Support Inspection Persur.=:"
Instruction QI-QP-2.1-19, " Qualification of Weld Inspection
Personnel" In the areas reviewed, the above documents appeared to be adequate to control activities for welding of cable tray support modifications.
b.
Observation of Work The NRC inspector observed the QC inspection of two cable tray supports, CTH-9727 and CTH-12808, in the reactor building.
Cable tray support CTH-9727 was inspected for structural members and welds specified on Drawing CTH-2-9727.
Cable tray support CTH-12808 was inspected for structural members, welds and Hilti bolts specified on Drawing CTH-12808.
The above supports were constructed from steel plate, angle iron, and channel iron.
No work was in progre s on cable tray support modifications involving replacement of structural members with tube steel.
In the areas inspected, the cable tray supports including structural members, welds, and Hilti bolts complied with Instructions QI-QP-11.10-2A and QI-QP-11.21-1.
c.
Review of Records The NRC inspector selected three of the tube steel modified cable tray supports, CTH-11535, CTH-11541A and CTH-11542 for review of the fabrication recerds The work package for each support contained the individual support drawing and the operational traveler. Although the work was incomplete, the traveler identified the weld procedure, the welders, and the QC inspectors for work that had been performed.
In the areas reviewed, the cable tray supports were welded by qualified welders using a qualified weld procedure and inspected by certified Level II QC inspection personnel.
No violations or deviations were identified.
