TheVDCSiscomprised ofacorporate levelgeneralprocedure andassociated reviewdocumentation forms,andisdesignedtotrackVendorTechnical Documents (VTDs)fromtheirreceipttofinaldisposition andfiling,utilizing positivefeedbackateachstagetoguarantee receiptandon-schedule review.Toassureimplementation ofandadherence totheVDCS,theAEPSCQualityAssurance sectionhas.beenassignedtheresponsibility formonitoring andauditingthegeneralprocedure.

VDCSOb'ectivesPriortothedetaileddevelopment oftheVDCS,itwasessential thatprogramobjectives bewelldefined.Theresulting objectives wererealistic, achievable, andaddressed theintentofGenericLetter83-28,Section2.2.2.Theseobjectives andthemannerinwhichtheywereaddressed aredescribed asfollows:1.Centralization ofResponsibility forVTDsBecausethevendorsusesuchdiversemethodsfortrananitting VTDstoAEP,theassigning toonecentralgrouptheresponsibility forreceiving, classifying, anddetermining distribution forallVTDswasaprimerequirement.

TheNuclearOperations Section(NOS)withintheAEPSCNuclearEngineering Divisionhasbeenassignedthisresponsibility.

AllVTDspertaining toD.C.CookPlant,regardless oftheirpointsofarrivalwithintheAEPSystem,willbeforwarded totheNOSforinitialprocessing.
