VY again; more trouble at the troubled plant

A little dab'l do ya (0.00 / 0)

Appears to have been a lack of lube:

Neil Sheehan, a spokesman for the Nuclear Regulatory Commission, said that the problem was traced to a lack of lubrication.

"They identified a lack of lubrication on the pilot (control) valve for the stop valve," Sheehan wrote in an email.

Tsk, tsk.

Once again (4.00 / 2)

Entergy proves that they are not responsible owners of the plant, and the plant is not reliable as a source of electricity for the state.

Non nuclear side (4.00 / 1)

Of the plant?

Can the state comment on 'safety' and reliability on this portion of the plant?

"Non-nuclear" is an interesting assessment. (4.00 / 2)

If it caused them to reduce power for two days, I think that characterization could be open to debate.

i love (4.00 / 2)

how its a 'nuclear' plant, and only the NRC can regulate it.

but when there is a safety issue, the spin is that it happened in the 'non' nuclear part of the plant.

is that outside the fence?
if it doesn't really affect the 'nuclear' part, why were they running at reduced power?

must be in the same section as those 'not' buried underground pipes.

Day 15,203 (4.00 / 2)

Remember Set 20th?  Oh, so long ago.  Murtha should have noted that these assholes can't even do a break-in/arson job right.  And we should trust them with our public health and safety?  Oops, somebody just dropped a lit match--god knows where.

So how's that "Preventative Maintenance Plan" working out (4.00 / 1)

"

In 2007, a failure in the turbine stop valves caused an emergency shutdown of the reactor. The problem was attributed to the lack of preventative maintenance on a valve bell crank mechanism.

On Aug. 30, 2007, a troubleshooting team entered the turbine building to inspect, lubricate and mechanically assist the No. 2 turbine stop valve mechanical linkage. The effort was successful and the valve stroked open, and indicated full open from the control room. Upon a subsequent retest, the valve was stroked closed and failed to open. The team then attempted to lubricate and free the linkage, after which the linkage was freed and the valve opened faster than expected, which resulted in a pressure deviation in the turbine stop valve actuator hydraulic oil system that resulted in the oil dump valves opening, causing all four valves to close.

An analysis of the reactor trip concluded there was no preventive maintenance activity to inspect, rebuild and lubricate the bell crank mechanism on a periodic basis.[..]As a result of the malfunction, a preventative maintenance plan was developed and implemented."

Apparently even after the so-called "preventative maintanance plan" was developed & implemented, valve still failed. Back to the drawing board boys.
