Functional or Program Areas Inspected 1.
Reactor Coolant Pressure Boundary Piping - Observation of Work and Work Activities The inspector observed the fit-up and alignment of Reactor Water Clean
'
Up System weld No. 1-RT-37-6-Q-1 on Traveller No. RT-37; rigging and handling on Nuclear Boiler System spool No. 1B21P018-C.
The inspector determined that work activities were performed in accord-ance with the applicable procedures and good construction practices were adhered to.
No items of noncompliance or deviations were identified.

Reactor Coolant Pressure Boundary and Safety Related Piping -Welding Material Control a.
Review of Documents The inspector reviewed the following documents:
(1) BA procedure No. BTS-402. Revision 14, " Procedure Specifica-tions for the Procurement, Storage and Control of Welding Filler Materials" (2) BA procedure No. BTS-402 (GE/ Weld Control), Revision 3,
" Procedure Specification for the Procurement, Storage, and Control of Welding Filler Materials" (3) Receiving Inspection Reports, Material Certifications, and Purchase Orders for ER308L welding rods with lot No.
C3548R308L and No. D3548R308L; E70S-2 welding rods with heat No. 065094; E7018 electrodes with heat No. 48949 and lot No. 026B620, heat No. 48985 and lot No. 026B618, heat No. 644657 and lot No. 026B208.
It was determined that the above documents met the PSAR, 10 CFR 50, Appendix B, applicable code and procedure requirements except that the phosphorus content (0.041%)
in the E7018 electrodes with heat No. 48949 and lot No.
026B620 exceeded GE/ Weld Control procedure (0.030 %).
However, the inspector determined that the electrodes in j
question were not used in the GE welds (paragraph 3)
observed by the inspector during this inspection.
It was suggested to the licensee that a review be made to ascertain that the electrodes in question were not used on GE welds.
