Luminant told NRC the unit experienced a loss of main feedwater.

"Operators observed [that] both main feed pumps tripped and [steamgenerator] levels decreasing," prompting the manual trip at 8:25 pm CSTSaturday (0225 GMT), Luminant said.

It said the reactor trip resulted in a turbine trip and that bothmotor-driven auxiliary feedwater pumps started and that the low steamgenerator levels triggered the turbine auxiliary feedwater pump.

NRC spokesman Victor Dricks said Monday that the "loss of the mainfeedwater pumps would automatically set in motion an automatic reactor trip,"but that operators saw the levels decreasing and tripped the unit.

No information was available on what caused the problem with the mainfeedwater pumps, Dricks said, noting that the unit is being maintained in asafe condition.

"All systems responded as expected," Luminant said. "There was no work inprogress at the time of the incident."

The adjacent 1,250-MW Comanche Peak-1 reactor continues to operate at100% of capacity, according to NRC daily reactor status reports.
