Independent Inspection Effort a.
Construction Activities (Unit 1)
The inspector conducted a general inspection of the fuel, auxiliary and reactor building to observe construction progress and construction activities such as welding, nondestructive examination, material handling and control, housekeeping and storage, b.
Storage (Unit 2)
On July 22 and 23,1981, the inspector made a general inspection of the Unit 2 construction site, the north lay down yard and the Vicksburg fabrication shop to observe material handling and control, housekeeping and storage.
The following conditions were noted:
(1) Several examples of safety related pipe spools off dunnage in contact with the ground and ground water, contrary to BPC Specifi-cation 9645-M-204.0.
(2) Numerous examples of safety related pipe spMis with missing, damaged or badly deteriorated pipe cape, entrary to BPC Speci-fication 9645-M-204.0.
(3) Numerous examples of safety related pipe spools sealed with badly deteriorated tape, contrary to BPC-Specification 9645-M-204.0.
(4) Several examples of e?fety related pipe spools containing water and debris, contrary to BFC-Specification 9645-M-204.0.
(5) Plastic covers, over two safety related valves, were melted by close proximity to heat lamps. The heat lamps were intended to prevent condensation on the valves.
(6) The licensee identified, by Condition Report (CR) 6051 that two items, of Class IE electrical equipment, were not stored in accord-ance with level C storage condition requirements.
The CR was issued on March 4,1981, and as of July 22, 1981 there had been no act;ons taken to identify or perform corrective action.
The above indicates that the licensee has not established adequate measures to control storage and preservation of equipment and materials. Failure o establish measures to control storage and preservation of materials and equipment to prevent damage is in violatten of 10 CFR 50, Appendix B, Criterion XIII.
This violation will be identified as 417/81-11-02, " Inadequate Measures to Control Preservation of Safety-Related Materials and Equipment".

Weld 512e (Units 1 and 2)
With regard to the above inspection, the inspector noted that the vertical welds attaching the top main support gusset plates to four Unit 2 MSRV quencher:;, as shown, on Drawing C-79-114 Revision 2, varied in length from less than five inches to over six inches. It could not be determined at the time of this inspection whether the above weld length variation was consistent with the drawing raquirements, or the design analysis.
Furtherr. ore, it could not be determined whether a similar condition exists in Unit 1.
The licensee,ndicated that they would look further into the matter.
The inspector stated that the above matter would be identified as inspector follow-up item 416/81-27-01, 417/81-11-01: "MSRV Quencher Weld Size".
Within the areas inspected no violations or deviations were iaentified except as discussed in paragraph 5b.
6.

Observation of Welding Work Activities The inspector observed field welding activities by inspection of weld joints and review of records associated with RCPB pipir g at various stages of weld completion. Observations were made in order to deter-
mine whether the requirements of applicable specifications, standards, work and/or inspection procedures are being met for the activities involved and in the following stages of weld completion.
Actual observation of work was not possible as the window of opportunity had past.
(1) The inspector examined records of weld joint fitup prior to welding, to determine whether identification / location, joint preparation and alignment, evidence of QC verification meet applicable procedures. The following weld joints were examined.
