OTHER FINDINGS OR COMMENTS:
1.
The NRC inspector reviewed test results of splices fabricated with j
3M Scotch 33+ Vinyl plastic electrical tape and Okonite splicing tapes numbers 35 and T-95.
This test was performed under Qualifica-tion Plan 17942-01 for Alabama Power Company for use in Farley Nuclear Plant.
- }
Fif teen specimens were included in the qualification test program.
^
The specimens represented splices installed on cables which supply fan motors and motor and solenoid o;>erated valves. Configuration of each specimen differed based on cable size, or insulating tape, or
. jacketing tape or splice overlap. Testing voltage and current for the specimens also differed depending on the application of each splice. The fabrication of test specimens was performed by Wyle Laboratories, Huntsville, Alabama. All materials for fabrication of the splices were supplied to Wyle Laboratories by Alabama Power Company.
All specimens were subjected to the following qualification sequence:
receiving inspection, specimen preparation, baseline functional test, radiation exposure, functional test, thermal aging, functional test, accident simulation and post-test inspection.
1 The test setup included a NEMA 1 enclosure with six specimens, three condulets with two specimens each and a Limitorque limit switch compartment cover with three specimens., The mounting of the six splices in the NEMA 1 enclosure was in a vertical direction where the "V" of each splice was oriented in the downward direction. The mounting of the splices.in the condulet and the Limitorque limit switch compartment cover was oriented in a horizontal direction.

REPORT INSPECTION Nn. oconnon9/A7_n?
RFSULTS-PAGE 3 of 4 The accident simulation test represented the main steam room (MSR) temperature and pressure profiles for a main steam line break and containment temperature and pressure profiles during a LOCA/HELB for Farley Nuclear Power Plant. All fifteen specimens were tested to the MSR and containment profiles. The MSR profile was conducted first followed immediately by the containment profile.
Leakage current was monitored for all specimens in the condulets at the -
initiation of the MSR and continuously for specimens in one condulet for the duration of the MSR and containment profiles.
Leakage current of 1 ma was measured for the spechnens in one condulet.
Wyle personnel suspected that the leakage current was self induced by two cables tied with nylon tie wraps outside the test chamber.
After the nylon tie wraps were cut and the cables separated, the leakage current dropped to zero. Review of the test results indicated that the test specimens demonstrated the capability to conduct the specified currents at the specified voltages during the accident simulation. The specimens were artificially aged for fifteen years equivalent life prior to the accident simulation.
The NRC inspector examined the qualification plan (QP) and related engineering documentation to verify the following:
a)
Adequate test instrumentation and their accuracies were described and used to meet the requirements of IEEE-STD-323/
1974.
b)
Equipment interfaces were addressed, c)
Test acceptance criteria were established.
d)
Same equipment was used for all phases of testing and represen-ted a standard production item.
e)
Environmental conditions were established and described (e.g.,
pressure and temperature profiles, f)
Test results were adequately reduced and evaluated against established acceptance criteria described in QP.
g)
All prerequisites for the given tests as outlined on the QP had been met, h)
Test equipment included a description of all materials, parts, and subcomponents.

Notice of Anomaly reports were properly documented.
j)
Appropriate margins applied.
1 With respect to 1) above:
An anomaly occurred during the accident simulation test program relating to the use of a high speed printer that was outside its calibration interval.
The printer was subsequently calibrated and was found to be within manufacturer's prescribed tolerance.
No nonconformances were identified.
