Junk Plant River Bend: Never Exceeded 20% Since Outage, then Scram

March 15

River Bend is at 80% again.

March 14

You gotta give it too them, they didn't give up. Restarted and up to their sweet spot of 19%.


***This guy started up from a extended outage sometime on March 8. Simmered along at 20% with turbine control issues. One wonders what work they did with the turbine control in the outage.

Least nobody sneezed in the control room at Grand Gulf causing a long and big down power or trip.

Arkansas Unit 2 has been a 50% for how long...

Profound capacity factor and economics problems across the whole southern Entergy fleet...

Event Text
MANUAL REACTOR SCRAM DUE TO CLOSURE OF THE MAIN TURBINE CONTROL VALVES

"At 0714 CST on March 10, 2017, with the unit in Mode 1 at approximately 17% power, a manual actuation of the reactor protection system (RPS) was initiated due to rising reactor pressure caused by the closure of the Main Turbine Control Valves (MTCV's). The cause of the closure of the MTCV's is under investigation.

"The unit is currently stable in Mode 3.

"All control rods inserted as expected; water level control is stable in the normal control band and reactor pressure is being maintained with steam line drains [aligned to the main condenser].

"The NRC Senior Resident Inspector has been notified."
