Subject:
10CFR21 Defect PRC 84-42 Topaz Inverter Low Voltage Shutoff
Dear Mr. Keppler:
On October 19,.1984, General Electric'(GE) Company notified Illinois Power of a potential reportable Part 21_
defect. Based on an evaluation, Illinois Power-Company is providing the following information to the Commission in accordance with the requirements of.10CFR Part 21.21(b)(3).
(i) D. P. Hall, Vice President of Illinois Power Company, by means of this report, hereby informs the Commission of a 10CFR Part 21 defect.
(ii) The basic component involved is one Class IE GE dedicated inverter (GE drawing 184C4723) used in the C61-P001 (Remote Shutdown System) panel. -
(iii) The components were supplied by:
General Electric Company Nuclear Energy Business Operations 175 Curtner Avenue San Jose, California 95125 (iv) The defect is the adjustment of the low voltage shut off and turn on for GE dedicated Class 1E inverters (GE Drawing 184C4723). This adjustment was set too high by~the original manufacturer (Power Mark, a Division of Topaz). Due to engineering error, the GE dedication process was checking for operable range of 105 to 140 volts DC, instead of 100 to 140 volts. Topaz has been routinely setting the low voltage shut off at 105 volts DC.

- ,4 U-600415 L16-86(01-25)-L 1A.120 Typical DC bus voltages are GE specified to range from 108 to 132 volts with momentary voltage dips to-105 volts DC during'the startup of large DC.
loads. This results-in a condition where the inverter may not start or restart until the voltage is increased, not just to 105 but to'above 118-volts DC (13 volt fixed offset). Since the-allowable momentary dip of the input bus voltage is equal to-the. factory preset inverter low voltage cutoff (105 VDC), this dip could result in an inverter trip and a failure to restart during a design basis accident. The primary effect of' loss of this power supply is that it causes loss of the-Reactor Core Isolation Cooling (RCIC) system as controlled from the Remote Shutdown System. Both these systems.are required for safe shutdown of the plant.
(v) Illinois Power Company received notification from General Electric Company of a potential Part 21 defect on this subject on October 18, 1984.
(vi) One inverter was confirmed to be on the Clinton site within the C61-P001 (Remote Shutdown System) panel. Two additional inverters were on order under Purchase Order X17174. No spare inverters-for this application were on site.
(vii) Corrective Action by GE consisted of the following:
- a. Issuing Revision 3 of drawing 184C4723 to-reflect the correct trip voltages.
- b. FDI-SKSZ and FDDR LH1-2998 were issued to provide the procedure for resetting the on-site inverter to the proper low voltage set point.
- c. GE Work Request i 396 was completed September 9, 1985, which verified that the inverter was operating properly.
(viii) Not applicable to Illinois Power.

-! Attention: Director of Inspection and Enforcement l In accordance with the requirements of the . Nuclear Regulatory Commission, and in particular 10CFR Part 21, we wish to inform you of a situation involving one of our engines located at Palo Verde Nuclear Generating Station of Arizona Public Services.
The engine in question - is known as a KSV-20-T. The twenty cylinders of this engine have a bore of 13.5 inches and a stroke of 16.5 inches. It is pure turbocharged and rated
-at 5000K at 600 RPM. The engine bears the Serial Number 7187 and is known at the Palo Verde plant as. Unit 111 Diesel "B".
On the morning of Tuest5y, December 23, 1986, and during a programed test run, the master power rod in the number 9
- location broke at a fractured surface. Extensive damage subsequently occurrL to both the power train components and the engine structure in the imediate area. This
, resulted in the engine becoming totally inoperable.
, A metallurgical examination of the fracture surfaces as well as an analysis of the chemical and physical properties of the rod forging has been completed. It is concluded that a fatigue failure originated in the rod when iron plating in the articulated rod pin bore failed in fatigue.
It was also determined that the chemical and physical properties of the rod forging material were within specification. The iron plating was used to correct a
?
dimensional error which occurred during machining.

, ,E.,e An' assessment of the damage sustained by the engine's structure and components is currently -being undertaken and details of_ a repair ~ program are being formulated.
More information' _on this aspect will be sent to you when this task has been completed.' ~
It should be noted, however, that all damaged areas can be properly repaired with the eng~ine in situ. ~
- _ =
A thorough examination of all pertinent records revealed that- three other m' aster rods were iron plated in a manner similar- to the one -which has failed.
i- Serial No. 8L1603 is installed in the number 2 throw of theOne rod bearing
. engine which experienced the failure.
._ l A second rod, Serial No. 7E1209, is the- sixth throw of engine -Serial No. 7186 which _is -also located at Palo Verde. The third rod bears 1 the-~ Serial humber GE1213 and was built into the number 3 T; throw - of engine Serial Number 7169 located at the Byron
! Generating Station of the Commonwealth Edison Company.
This rod has already been replaced with a new one and the engine returned to service. -
