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. ;

POTENTIAL ENFORCEMENT FINDINGS

'
Alabama Power Company Docket Nos. 50-348, 50-364 l
Joseph M. Farley Nuclear
l
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)

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. Specifically- ~

'(3) A' commercial grade; torque switch was installed into a safety-related

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.

(5) A commercial grade'Agastat timing relay-(ATR).was installed'as a

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
