SAFETY PARAMETER DISPLAY SYSTEM OUT OF SERVICE FOR GREATER THAN 1 HOUR
"At 1603 hours on 12/25/02, the Safety Parameter Display System (SPDS) portion of the Emergency Response Facility Computer System (ERFCS) was noted to be inoperable, due to all outputs being displayed in magenta color.
"Troubleshooting of the ERFCS determined that the Central Emergency Operations Facility (CEOF) input into the ERFCS was causing the system to fail. The CEOF input into the "A" ERFCS was defeated and at 1714 hours on 12/25/02 the ERFCS and SPDS were returned to service,
"SPDS was out of service for greater then 1 hour, which is considered a major loss of emergency assessment capability.
"This report is being made in accordance with 10CFR50.72(b)(3)(xiii).
"The NRC resident inspector was informed."
