Subject:
10CFR PART 21 DEFECT ADS DIGITAL SIGNAL CONDITIONER CARD FUSE FAILURES
Dear Mr. Keppler:
On July 21, 1983 Illinois Power Quality Assurance (IFQA) received a Potential Defect or Noncompliance (10CFR21) Referral from Nuclear Station Engineering Department (NSED) concerning the failure of automatic depressurization system (ADS) initiation due to blown fuses. Based on an evaluation, Illinois Power is providing the following information to the Commission in accordance with the requirements of 10CFR Pair 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 components involved are digital signal conditioner (DSC) printed circuit cards used in the Nuclear System Protection System (NSPS). A list of the NSPS printed circuit cards by parts list (PL) number, title, and abbreviation is included with this report as Attachment "A".
(iii) The NSPS printed circuit cards were manufactured and supplied by:
General Electric Compaay Nuclear Power Systems Division 175 Curtner Avenue San Jose, CA 95125 (iv) During construction and initial operation (C&IO) testing, the ADS logic failed to actuate the safety relief valves in response to automatic or manual signals. The failure was attributable to a blown fuse (F3) on the DSC card. When fuse F3 blows, a card-out-of-file signal is annunciated in the main SEP 221983 8309270288 830919 PDR ADOCK 05000461 -
S PDR [
s Mr. James G. Keppler Page 2 September 19, 1983 control room, and the power-on-initialization logic is prevented from initiating the ADS function in that division.
The ADS is an engineered safety feature subsystem of the emergency core cooling system. ADS provides pressure relief during a loss of coolant accident in which the high pressure core spray fails to provide a sufficient volume of water to the reactor, and allows the low pressure core spray system to successfully cool the reactor vessel. The blown fuse on the DSC card would result in a deficiency in the function of the ADS and could, under operating conditions or an operating ,
transient, contribute to the exceeding of a safety limit. In consideration of an independent single failure, a blown fuse on the ADS card could result in loss of a safety function necessary to mitigate the consequences of an accident.
(v) NSED informed IPQA, by means of the Potential Defect or Noncompliance (10CFR21) Referral on July 21, 1983, of a potentially reportable defect in the ADS initiation logic.
(vi) A list, showing the number and location of each type of NSPS printea circuit card at Clinton Power Station, is included with this report as Attachment "B".
(vii) Investigation has revealed the cause of the fuse failures to be attributable to GE's assignment of pins in the card edge connector. Card edge connector (P2) pin (P2-21, u) provides a fault path to the card out-of-file interlock signal present at pin (P2-22, v).
When the card edge connector (P2) is either connected to, or disconnected from the card, pins (P2-21, u and P2-22, v) momentarily short and the subsequent fault I current is sufficient to open the fuse on the DSC card.
The NSPS printed circuit cards have been returned to GE in San Jose, CA. GE will implement FDDR No. LH1-777 to replace fuse F3 on each DSC circuit card with a 2.2 Kchm resistor to limit the power bus load to 5.5 mA.
This work is expected to be completed by September 23, l
1983. A subsequent test of each card by the Terradyne l
card tester is expected to be completed by GE by February 1, 1984.
All other printed circuit cards in the NSPS panels will be reviewed (schematically) by Illinois Power (NSED) for edge connector pin assignments for all fused signal paths. Completion of this action is expected by December 1, 1983.
