Junk Plant pilgrim: Continued Unreliable SRVS

They replaced all the solenoid valves. One wonders if heat damage caused this. Are these guys type 1.

2 stage
LER 17-007-00

On April 24, 2017, during Refueling Outage 21 while performing testing on the Pilgrim Nuclear Power Station (PNPS) Safety/Relief Valves, a high resistance was measured across the solenoid pilot valve coil of SV203-3A. This solenoid pilot valve was replaced during Refueling Outage 21. After the solenoid pilot valve was removed it was transported to an offsite vendor for additional testing.
