Post Office Box 2641 Birmingham, Alabama _35291-0400 ~ 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.

. .- . , 1 POTENTIAL ENFORCEMENT FINDINGS ] - - , .
Alabama Power Company Docket Nos. 50-348, 50-364 l ' l Joseph M. Farley Nuclear License Nos. NPF-2, NPF-8 ! Plant Units 1 and 2 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 - inspection and remained in this unanalyzed condition until it was identi- - 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 - . Power's engineering review were implemented. (50-348,364/87-11-01) 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) 1 3. The licensee installed numerous commercial grade parts at FNP Units 1 and 2 ~without adequately evaluating their suitability for use in safety-related applications.

A'c6mmercial grade Hamco. limit switch was installed"as a replacement ~ , for safety-related switch for the accumulator: tank isolation valve.- . '(3) A' commercial grade; torque switch was installed into a safety-related
' Limitorque motor. actuator.' Limitorque has _ stated that although the - a - isafety-related and commercial grado' torque switches for outside . Containment are the same, the switches'that were ordered'as safety o related receive additional-QA checks at Limitorque not performed on the' commercial-grade switches. No additional QA checks were made at FNP:on this switch. (4)- Commercial grade hinge pin bushings were installed'in safety-related , ' Anchor / Darling tilting disc check valves in the auxiliary feedwater , system.- g " (5) A commercial grade'Agastat timing relay-(ATR).was installed'as a ' replacement in safety-related panel #Q2R16B007_-B, 600 volt. load -distribution panel. Additionally, commercial grade:ATRs were'found in'other safety-related_ electrical _ enclosures including two ATRstin ' diesel generator load. sequencer panel #Q2R43E5018-B. and two ATRs'in diesel generator relay terminal box ll0lR43E506-B.- ~ -(50-348, 364/87-11-03) j _ 4. - The. licensee neither restored two non-functional safety-related control ' room fire ventilation dampers within the 7 day Technical Specification . req'irement nor. submitted its special report to the NRC, as required. u .within 30. days. and:the licensee failed to report to the NRC a degraded safety-related.125-V auxiliary building battery condition in both. trains A and B of Unit 2 that was discovered in April of 1986 by FNP personnel. T 'The battery degradation involved 15 cracked battery cell cases, 3 ini l , , battery room'2B and 12 in battery room 2A. Corrective. action was performed.
