Limerick Nuke Plant Unit 2 Offline

The unplanned shutdown was required to replace a steam valve.

According to a press release from Exelon Limerick Generating Station, the plant's Unit 2 needed an unplanned shutdown, or "scram," around noon for the replacement of a steam valve. 

"There are 14 steam valves on each unit that protect the main steam line," said communications manager Dana Melia. 

Melia said that plant operators are constantly monitoring all the parts of the system, and noticed a rise in the steam temperature.

"That indicated a potential failure [in the steam valve]," Melia said.

These types of repairs can only be done with the unit offline. The valve will be replaced and the system checked before the unit is restarted. 

The repairs to Unit 2 come less than 48 hours after that the plant's Unit 1 had returned to full power. Unit 1 was following what the company and the Nuclear Regulatory Commission described as an electrical fault.

Unit 2 during a scheduled outage that lasted about two weeks and brought hundreds of out-of-town workers to the facility.

The power station is in the middle of a relicensing application process that, if completed successfully, would allow the facility to remain in operation until the year 2049.

The has been only one tower running for weeks. You can clearly see when one is off line as no steam comes from it. This seems like pretty old "news".

No...unit 1 was scrammed and offline for about a week for switchgear failure. This is a new scram on unit 2.

Maybe someone needs to go to the eye doctor. He can't see clearly as he thought. Bahaha

The valves are an ongoing problem. They've been working on them on and off for quite a while now. First the turbines, then the valves. This nuke is going on 30 now and they want to relicense it until 2049? Can't wait to see what happens with this thing in the coming 30 years. Geez.
