Junk Plant Nine Mile Point 1: Grossly Insufficient Maintenance

Grossly insufficient maintenance on the turbine control system. Run to failure. Is more troubles on the way. It sounds line steam or water got into the hydraulic system. They shifted to the standby system. It questions the readiness of all standby systems. 

Licensee Event Report (LER) 2017-002, Manual Reactor Scram Due to Pressure Oscillations

On March 20, 2017 at 02:27, Nine Mile Point Unit 1 performed a manual scram of the reactor due to pressure oscillations. This event is reportable under 10 CFR 50.72 (b)(2)(iv)(B) and 10 CFR 50.73(a)(2)(iv)(A) as any event or condition that resulted in a manual or automatic actuation of any of the systems listed in 10 CFR 50.73(a)(2)(iv)(B).
The Unit was offline and reactor shutdown was in-progress at the time of the scram. The cause of the scram was manual scram. The scram was required at approximately 4% reactor power when pressure oscillations occurred exceeding the procedurally required limit. The apparent cause of this event was Mechanical Pressure Regulator (MPR) oscillations caused by a combination of the fouling of the MPR' s pressure sensing bellows line and a bypass relay linkage passing through a worn bushing which created a friction induced sticktion of the linkage.
The event described in this LER is documented in the plant's corrective action program.
