Junk Plant Seabrook Trips On Bum Transmission Work

Update 3/3

Equipment problem shuts down nuke plant 

 

SEABROOK — An equipment malfunction triggered the safe shutdown of NextEra Energy Seabrook nuclear power plant early yesterday morning, according to the Nuclear Regulatory Commission.

According to NRC Region I spokesman Neil Sheehan, at 2:53 a.m. Wednesday, Seabrook Station plant experienced an unplanned shutdown because a turbine tripped, or went offline.

“That triggered, as expected, a reactor shutdown,” he said. “The shutdown was uncomplicated. Turbines are considered to be the secondary, or non-nuclear, side of the facility.” 

Sheehan said the NRC’s resident inspectors assigned full-time to Seabrook Station were promptly notified about the shutdown. 
“The senior resident inspector responded to the plant, reviewed the sequence of events, performed visual inspections, and discussed the shutdown with key plant personnel.” Sheehan said. “The inspectors will continue to follow up on the company’s assessments of what occurred, (as well as) any repairs and planning for the restart of the unit.” 
The NRC monitors all happenings at the nation’s nuclear power plants, even when they are not related to the nuclear side of the plant. 
“We care about a turbine trip because it initiated the reactor trip,” Sheehan said. “And any time that occurs, you’re putting unnecessary stress on the (power plant’s) operators.”
NextEra Energy Seabrook spokesman Alan Griffith confirmed the plant’s shutdown. Griffith said the plant is designed to shut down when such issues occur to ensure safety, and it functioned appropriately Wednesday morning. 

As of yesterday afternoon, Griffith said, the exact cause of the equipment issue that triggered the shutdown had not yet been determined. 
“As safety is our highest priority,” Griffith said, “a complete and thorough analysis is being conducted on the exact cause of the shutdown. While there is no timetable, the plant will be returned to full power once repairs are completed.” 
Sheehan said along with plant personnel, the NRC’s resident inspectors will be involved in all aspects of the assessment.

 

 

So Seabrook tripped yesterday and why isn't this reported on?

So it happened last night at 02:52.

Check out how sensitive our grid is to the lost of Seabrook. It tripped around 3 am. It is getting doubtful the transmission work caused the trip. NEISO electricity has been pretty inexpensive this mild winter. This has made a lot of long term contracts bankrupt?

Event Text

TURBINE TRIP CAUSING A REACTOR TRIP "The turbine tripped for an unknown cause followed by a reactor trip. All systems are functioning as designed. Operators have transitioned out of the EOP [Emergency Operating Procedure] network into normal operating procedures. The plant is stable in mode 3." All control rods fully inserted during the trip and no safety or relief valves lifted. The plant is in its normal shutdown electrical lineup. Emergency Feedwater actuation occurred to restore steam generator levels. The plant expects to make a press release. The licensee notified the NRC Resident Inspector.
