Dear Sir:

Mr.G.S.Spencer, Chief ANPP-17230-BSK/JAR February 12, 1981 Page 2 cc: Victor Stello, Jr., Director Office of Inspection and Enforcement U.S.Nuclear Regulatory Commission Washington, D.C.20555 A.C.Gehr Snell&Wilmer R.L.D.B.W.E.A.C.J.M.J.A.W.H.W.G.W.J.R.L.R.W'.D.R.Robb Fasnacht Ide Rogers Allen Brand Wilson Bingham Stubblefield Patterson Welcher Hawkinson

FINAL REPORT REPORTABLE DEFICIENCY 50.55(e)ARIZONA PUBLIC SERVICE COMPANY (APS)PVNGS UNIT 82 1 I.Descri tion of Deficienc The referenced drawing for the Fuel Building specifies three (3)f/10 additional rebar reinforcement below the beam at Elevation 167'-6" on the south exterior wall, between column lines FA and FD.These additional rebar were not included in Placement 2F025 T.O.C., Elevation 167'-6".A review of this deficiency indicates that it is an isolated case attributed to oversight.

II.Anal sis of Safet'Im lication This condition is considered reportable since if left uncor-rected, the wall could possibly experience localized over-.stressing under seismic conditions; however, an analysis was not performed since the condition was being corrected to a level equivalent to the original design.III.Corrective'Action The required additional rebar were installed above the original location within the next placement-and properly anchored by extending into the west wall and by development length beyond the required point at the east end on.the south wall.This repair disposition for the referenced NCR.provides a condition which meets the project design requirements.

The dispositioned NCR C-F-2339, attached, includes a repair sketch for installing the additional rebar.Since this is an isolated case, additional corrective action to prevent recurrence is not required.
