DISCUSSION. FINDINGS. AND CONCLUSIONS:
Discussion:
On April 3,1985, AMP Products Corporation, manufacturer of pre-insulated diamond grip (PIDG) terminal lugs, sent a letter to F. W. Chandler (App. A, 5.ff) stating that use of PIDG terminal lugs with solid copper conductors proved unsatisfactory in tests under any voltage or current condition. An April 23, 1985 memo from J. C. Standifer to G. Wadewitz instructed WBN to replace the PIDG terminal lugs that were installed on solid wires.
NCR 6076 R0 (App. A, 5.b) was issued on May 13, 1985, identifying this condition. The NCR revealed that AMP PIDG terminal lugs have been employed with solid copper conductors on safety systems for the installation of small electronic components. Westinghouse responded to NCR 6076 in their letter of May 24, 1985 to J. A. Raulston (App. A, 5.gg).
They stated that, based on discussions with the author of the AMP April 3, 1985 letter, they determined that the AMP tests on the PIDG terminals used relatively high voltages and currents which resulted in basic msterial breakdown of the terminal lugs.
They concluded that since the
- Foxboro H-line process equipment was low voltage and low current, the PIDG lugs would maintain structural and electrical integrity l
for the life of the plant if terminal lugs were installed properly. They went on to state that problems with the lugs would be detected during periodic tests and that no history of problems was known to exist at WSN or SQN. On this basis, the use of PIDG terminals is acceptable to Westinghouse.
A June 17,1985 memo from Standifer to Wadewitz (App. A, 5.x) stated that on the basis of Westinghouse's evaluation (App. A, 5.gg) and the fact that TVA's use of the PIDG terminals is for similar control loop applications, the PIDG terminal is satisfactory in this application. This memo dispositioned the NCR to "use as is".

An NSRS investigation of employee concerns from June 17,1985 to July 26, 1985 was reported on September 23,1985 in I-85-101-WBN (SQN)-1 ( App. A, 5.hh). The NSRS report included the following findings related to the use of PIDG terminal lugs at SQN:
a.
" AMP Corporation attempted to _obtain UL approval for the use of the PIDG Terminal Lugs on solid copper conductor wire but was unable to because of test failures (UL 486)."
b.
"Foxboro drawing specified Burndy terminal lugs.
- However, e
Foxboro racks contain AMP terminal lugs (PIDGs)."
t c.
"As a result of interviews with SQN personnel, it was learned that Foxboro had soldered over some terminal lugs (PID6s) in the Foxboro racks."
i d.
"Although Westinghouse had accepted the usage of PIDG terminal lugs on soljd wire in the Foxboro racks, the justification for their approval of the termination process in view of the problems (broken wires, loose connections, etc.) and failures experienced at both plants was considered h
by NSRS to be questionable. Westinghouse had apparently not had knowledge of these failures during their evaluations and had erroneously assumed '... no history of any terminal lug problem has ever existed at either plant.'"
e.
"Although Nonconformance Report (NCR) WBNNCR6076 was generated for WBN, OE as well as DC management personnel were aware of existence of the same nonconforming condition at l
SQN. Nonetheless, an NCR was not generated for SQN."
h f.
"The PIDG terminal lugs have been installed in safety-related systems and failures have been identified at both plants.
i Therefore the potential exists for the degradation of those safety-related systems."
g.
"SQN has experienced failures in test point resistors in the i
Foxboro racks.
Crimp failures resulted in additional 1.
resistance in the test point resistors, which are 10 to 100 ohm resistors with 1 percent tolerances.
Problem test e
l point resistors have been replaced with test point resistors l
where the terminal lugs have been crimped on and then t
soldered.
i
" Interviews with responsible personnel at SQN revealed that all PIDG terminal lugs utilized in the security system and
[
f.p.
crimped on solid wire were replaced with terminal lugs
[
Nd appropriate for the application."

)
In response to a draf t of the NSRS Report No. I-85-101-W8N, W8N l
Project Management Organization (PMO) conducted telephone 3
interviews with operations and construction personnel (R.C. McKay memo to PM0 Files, App. A, S.s; 08/07/85) to determine if the failure history of the discrete electronic components was due to the misapplication of PIDG terminal lugs. The results of these interviews at the Sequoyah Plant are:
f o
No failure could be directly or indirectly attributed to the misapplication of the PIDG terminal lugs.
t h
o A program for soldering terminal lugs was started in 1976-1977 and continued after transfer from OC to NUC PR.
I o
Test point resistor failure of the Foxboro instrument racks
(
was not attributed to the PIDG terminals lugs because the
}
failures continued after they were soldered.
I On August 6, 1985, Regulatory Engineering Section (RES) issued
(
Operating Experience Review OER SQN8850024001 ( App. A, 5.a) which p
documented random inspections and interviews performed at Sequoyah.
The inspections and interviews revealed the application j
- of PIDG terminal lugs in several areas:
- 1. Fire damper fuse links
- 2. Solenoid valves suppression networks 4
- 3. D/G control panel and logic relay panel
(
- 4. 6.9 kV breaker control logic i
- 5. Conax Connectors
- 6. 125 V de vital battery board
- 7. 480 V shutdown board
- 8. Vital inverters 03270 - December 5, 1986

PAGE 7 0F 15 The OER also indicated that Specification Revision Notice SRN-G-38-6 was issued to initiate the revision to General Construction Specification G-38.
The revision specifies the AMP approved SOLIDSTRAND terminal lug for solid conductors.
H. G. Parris memo to K. W. Whitt dated September 13,1985.( App. A, 5.cc) responded to the draf t NSRS report and initiated corrective action to solder or replace all safety-related PIDG terminals except those used on surge suppression networks. These networks l
are used on solenoid valves and 6.9kV and 480 V shutdown board status monitoring relays. The memo stated that solenoid valve surge suppression networks will be addressed on a second priority as the surge suppression networks do not provide a safety function and serve only to enhance the life of the contacts in the circuits that power the solenoids.
(Note: Although this does not specifically address the 6.9kV and 480 V shutdown board status l
monitoring relays, the response would be applicable).
I A pull test and resistance measurements of PIDG terminal lug crimped to one end of a diode were performed by TVA Central Laboratories ( App. A, 5.j).
Ten terminal lugs on solid conductors (r$y3#
were tested on 10/04/85 in accordance with Sequoyah Nuclear Plant Special Test Instruction STI-3 R0 ( App. A, 5.h; 10/02/85).
The test results showed that the average contact resistance between the terminal lug and solid conductor was less than 0.00125 ohm.
All 10 terminal lugs withstood a gradual application of 8 pounds of force without evidence of slippage between the conductor and l
terminal lug. The minimum force causing separation was 28.5 pounds.
Even though the test results appeared favorable the i
decision was made to proceed with the modifications.
l
' Subsequently, SQN completed inspections of more than 1.300 terminal connections in various areas (TVA memo from Abercrombie to Parris, App. A, S.g; 11/15/85). These inspections evaluated the rework as follows:
Area Inspected Rework Fire damper fuse links All rework complete MSIV solenoid valve suppression Rework not required (safety-i l

PIDG terminal lugs, Special Maintenance Instruction SMI-2-317-25 i
RO, (App. A, 5.1), was issued for SQN Unit 2 on 01/24/86.
Its purpose was to require soldering of all AMP (PID6) terminal lugs or replacement with AMP (SOLIDSTRAND) terminal lugs for all solid conductors in the critical systems and components found in the previous inspections.
TVA SQN Generic Concern Task Force report on EC #PH-85-003-003 l
- (App. A S.k; 05/06/86) stated that Unit 2 rework has been i
completed for the areas identified above. Similar rework will be completed for Unit 1 before it is restarted. The report recommended that EE8 review the results of the test conducted by l
TVA Central Laboratories because rework "seems" to be unnecessary in view of the test results.
EE8's response was to take a more conservative approach (i.e., soldering or replacing PIDG terminal 4
i lugs).

A September 15, 1986 memo from P. R. Wallace to D. W. Wilson (App.
A 5.ee) requested DNE's position on the need of surge suppression network in the solenoid valve circuit. A draf t memo f rom D. W.
Wilson to P. R. Wallace (App. A, 5.p; 10/24/86) expressed EEB's position on surge suppression network. This memo stated that the purpose of surge suppression networks is to protect circuit contacts against pitting and burning caused by arcing associated with breaking the inductive load current of the solenoid valve.
i Therefore, the reliability of PIDG connectors used on surge i
suppression networks should be assured.
The memo also stated that l
PIDG connectors on surge suppression networks associated with solenoid valves required to perform a safety function must be replaced or soldered prior to restart.
For the remaining class lE j
surge suppression networks, inoperability would not create an i
immediate safety problem, but over a period of time excessive i
contact wear would increase the potential for a contact failure.
I i
Therefore, field testing prior to restart must assure that the i
surge suppression networks have not developed an open circuit.
I This test should be repeated periodically until the surge j
suppression networks are permanently fixed by replacing or soldering the PIDG terminal lugs. This memo has not been fonnally 3
i M
issued, and no followup program has been identified for closing out
{
the recommended actions.
Findings:
AMP Products Corporation (manufacturer of PIDG terminal lugs) stated that, on the basis of its engineering department's l
evaluation and tests previously perfonned, using PIDG terminal lugs on solid conductors is unsatisfactory (App. A, 5.f f; 04/03/85).
Reduced current capacity could occur if terminal lugs are improperly installed.
i-A rework program (soldering or replacing the existing terminal j
lugs) was performed and completed for SQN Unit 2 in all safety-related applications with the exception of the surge suppression networks for solenoid valves. TVA must perform similar l
rework for SQN Unit 1.

Conclusion:==
The concern regarding improper use of PIDG terminal on solid conductors is valid. The adequacy of this application was found to be deficient and corrective action has been taken.
Rework on these terminations was completed for Unit 2 except for the rework on the surge suppression networks.
TVA must implement the similar rework l
for SQN Unit 1.
DNE is recommending that all PIDG terminal lugs in surge suppression networks for safety-related circuits be replaced or soldered but no plan for this work presently exists.
