                    Gentlemen:

                    This letter transmits the report of the inspection conducted at the Joseph M.
                    Farley Nuclear Plant (FNP), Units 1 & 2, by Messrs. R. P. McIntyre, J. B. Jacobson,
                    P. J. Prescott, J. J. Petrosino, of the Vendor Inspection Branch and D. R.                                    i
                    Lasher of the Instrumentation and Controls System Branch on May 11-22 and
                    June 1-5, 1987. The inspection was related to activities authorized by NRC.
                    License Nos. NPF-2 and NPF-8. Our findings were discussed with Mr. J. D.
                    Woodafd and other members of your staff at the conclusion of the inspection.
                    The purpose of-this inspection was to review the implementation of your procure-
                   ment and vendor interface programs at FNP by examining the respcnse of Alabama                                 1
                    Power Company.to specific vendor-related technical issues of safety significance.
                   The results of the inspection show considerable weakness in the areas of
                   procurement and vendor interface. The Alabama Power Company vendor interface
                   program appears to lack the rigor and formality necessary to achieve its
                    int 9nt. Several examples are cited in this report where, although Alabama
                   Power Company had been made aware of a problem by a vendor, complete, effective'
                   and timely corrective action was not taken. In addition, significant deficiencies                              ,
                                                                                                                                  I
                   were found in the procurement of both safety-related and comercial grade
                   components, resulting in hardware being installed in safety-related ap)11 cations                              i
                   which may not have been capable of aerforming its intended function. T1ese
                   findings, when considered along wit 1 the improper installation of the service

f water battery rack and the failure to report to the NRC the inoperability of 2

                   control room fire dampers and 15 cracked battery cells in both trains of the
                   auxiliary building batteries indicate a leck of systematic attention to detail.                                i
                   While no instances were found where Alabama Power Company failed to receive
                   information as a result of its lack of a formal arocess to periodically contact
                   key vendors, a number of cases were identified w1ere the information had not
                   been obtained from the vendor or VETIP but was obtained fortuitously from other
                   sources.
                  The findings discussed above have been classified as four Potential Enforcement
                  Findings (50-348 and 364/87-11-01 to 04, enclosed) and will be referred to
                  the hRC Region II office for appropriate action.                                                                ;

                     As a result of the inspection conducted on May 11-22 and June 1-5, 1987, the
                     following Potential Enforcement-Findings were identified.
                     1.-       The NRC inspectors observed-that both train B 125-v Service Water (SW)
                               battery racks were improperly installed and mounted, therefore creating
                               an unanalyzed condition concerning seismic qualification. Specifically,
                               the concrete anchor bolt nuts on all train B battery rack anchors were
                               backed off and used as leveling nuts for the rack thus providing no preload
                              on the concrete anchors. The battery racks were improperly installed in
                              the SW train B battery room approximately 1 year prior to the time of this

                              fied by the NRC inspector. Further, the inspectors identified six instances
                              where the licensee had failed to take adequate corrective action: (1) a
                              Henry Pratt, May 1985, 10 CFR 21 notification detailing problems with
                              Pratt valves using Limitorque operators was not correctly or completely
                              dispositioned; (2) an Anchor Darling, August 1r , 10 CFR Part 21 notifica-
                              tion concerning failures with tilting disc cher valve hinge pin bushings
                              was not completely dispositioned in that only u.eck valves in the auxiliary
                              feedwater system were inspected, (3) conditions noted in NRC Information
                              Notice 84-83, which concerned cracks on GNB battery cells caused by the
                              use of hydrocarbon based solvents for cleaning purposes were not completely
                              corrected, since only two of three electrical maintenance procedures were
                              revised to address the problem, (4) the review of a November 1984 Ruskin
                              10 CFR 21 letter concerning the failure of fire dampers to completely
                              close during flow conditions showed that the licensee identified this
                              problem in three areas, corrected it in two areas but did not correct two
                              dampers in the control room area, and (5) a Colt Service Information
                              Letter (SIL) A-2 dated February 1985 was evaluated by the licensee, but
                         ' not all the corrective actions determined to be appropriate by Alabama         .

                    2.       The licensee installed nine circuit breakers with questionable seismic           !
                             qualification and voltage ratings into safety-related motor control centers
                             at both FNP Units 1 and 2. The circuit breakers, that were affixed with
                             an Underwriters Laboratories, Incorporated, rating of 480 V by the original
                             manufacturer, were sold by Satin American Corporation as seismically
                             qualified safety-related circuit breakers acceptable for installation
                              into FNP's 600-V motor control centers.    The vendor provided no basis for
                             seismic or 600-V qualification. No testing or analysis that would qualify
                             the use of these breakers as installed has ocen done either by the licensee
                             or the vendor.    (50-348, 364/87-11-02)
