l 2 Unresolved Items Unresolved items are matters about which more information is required to determine whether they are acceptchie or may involve violations or deviations. One new unresulved item identified during this inspection is discussed in paragraph Independent inspection Effort ConstructionProgress(Unit 2)

The inspector conducted a general espection of containment and auxiliary building to observe construction progress and construction activities such as welding, coatings, material handling and control, housekeeping and storag Within the areas examined, no violations or deviations were identifie . Safety-RelatedPipeSupportsandRestraintsSystems(50090) Unit 2 Observation of Work and Work Activities The inspector selected the following two hangers / supports in the area of dynamic pl)e supports and component supports structures that had *

been QC final inspecte Documentation for the installation, inspection and design were reviewed; the hangers were reinspected with the assistance of QA/QC inspectors; and the results discussed with the QA/QC inspectors to determine the effectiveness of the hanger progra Hanger Numbig Syttem M 2-R-CA-1645 Auxiliary Feedwater Double #6 Springs 2-R-CA 1626 Auxillary Feedwater #3 Spring The above hangers were reinspected against their detail drawings for configuration, identification, fastener / anchor installation, clearances, member size, welds, and damage / protection, in general, the hangers were installed in accordance with design documents with the exception of the items identified by the inspector listed belo T1e inspector observed that for support 2-R CA-1645, the southeast anchor bolt has a gap of 1/8" between the washer and the baseplat The washer was being held up by the east weld between the tube steel and baseplate. This is contrary to Construction Procedure CP 115, ;

" Installation of Concrete Expansion Anchors." During the review of the l documentation for the same hanger, both CP 635A form, dated August 28, 1984, and a CP 635A stamp, Indicate that there are only two non-NF weld Hanger sketch, Revision 2, sheet 1 of 4 shows three non NF weld . _ _ _ _ - _ _ _ _ ._____- -_ -

Not identifying and listing all non-NF welds on CP-635A forms is contrary to Construction Procedure CP-635, " Documentation of Non-NF Hanger Welds by QC Inspectors." Review of QC Documentation and Records i The inspector selected the following sample of 10 hangers / supports QC documentation packages in the area of dynamic pipe supports and I component su) ports structures that had been QC final inspected and l final QA rev<ewe j Hanger N Coment/ Discrepancy l 2-A-NI-4210 - None 2-A-N!-4227 - None 2-R-NS-1119 - M-51C - Final Walkdown - No QA Signature l 2-R-CF-1620 - None 2-R-VX-1007 - None i 2-R-NM-1251 - None  !

- Non-NF Welds that had been deleted due to redesign were not correctly identified or ,

deleted on Form CP-635A j The discrepancies noted in paragraphs 6.a and 6.b are contrary to the procedures as noted, as required by Criterion V of Appendix B to 10 CFR Part 50, " Instructions, Procedures and Drawings", and is identified as Violation 50-414/86-08-02, " Failure to Follow Procedures During Instal-lation, Inspection and Review of Quality Assurance Documents for Pipe Supports / Restraints." During inspection of com)onent supports, the inspector noted that various spring setting ' load indication plates, NPT plates and identifying markings for hanger identification were painted over. With respect to hanger identification, lack of clear markings makes quick identification very difficul Another concern is that the pivot axials and washers of constant spring supports were noticed to be covered with paint, having a possible effect of decreasing the ability of the spring to function as required by their design. Also that pivot bushings in paddles of snubbers were also coated with pain Pending review and evaluation by the licensee and further NRC inspec-tion, this matter was identified as Unresolved Item 50-413/86-06-01 and 50-414/86-08-01, " Control of Coatings on Pipe Supports / Restraints."
