TMI Is Junk: Fire Alert!

 I count a least two overload current protection devices that failed to operate properly. What is the extent on condition, cause with all current protection devices at TMI and Exelon nuclear? A protection device had to trip the bus?

Like to see the maintenance on the motor/breaker.

Is the end of Three Mile Island near?

Two fires?

DAUPHIN COUNTY, Pa. —A spokesman for Three Mile Island in Dauphin County says an electrical short on a motor caused a brief fire at Three Mile Island on Monday night.

"The U.S. Nuclear Regulatory Commission (NRC) is continuing to follow up on the “Alert” declared just after 9 last night at the Three Mile Island 1 nuclear power plant. (An “Alert” is the second-lowest of four levels of emergency classification used by the NRC.) The “Alert” was declared in response to a fire in a pump that is part of a system would be used to help remove decay, or residual, heat following a reactor shutdown. The pump’s motor and electrical breaker were affected.

Does this mean really two fires. Did the switchgear fire alarm go off and did the fire extinguisher system activate?

The pump’s motor and electrical breaker were affected.

Weren't they just talking about permanently shutting this guy down?

It is safety related having a fire at a nuclear plant and getting into a alert.

This is a official NRC strategy ...why do they neglect to identify the specific component and system of the failed component. This all is called official NRC protection of the nuclear industry. How do you protect the nuclear industry, is not having incidences like this. Shielding them from accountability is making it worst. Of course, the newspaper might just not be reporting it.

Hmm, are they up at power or in a outage? They are at 100% power?

Small fire at pump at Three Mile Island nuclear plant

The U.S. Nuclear Regulatory Commission said Tuesday it was continuing to follow up on the event.

An alert was declared at the plant. That is the second lowest of four levels of emergency classifications used by the agency.

There were no injuries or off-site impacts, though the Londonderry Fire Company was called to the scene, but not needed.

Nuclear Regulatory Commission spokesman Neil Sheehan said one of the agency’s resident inspectors responded to the plant and performed an independent assessment of operator actions, equipment response and any damage. “No immediate performance deficiencies were identified,” Sheehan said.

The agency will now follow up on the company’s review of what caused the fire and repairs.

The portion of the decay heat removal system affected by the fire remains out of service, pending repair work.

The pump that caught fire is part of the system that circulates water to cool plant equipment. The pump’s motor and electrical breaker were affected. Exelon, the plant’s owner, said the motor on the pump overheated.
