MANUAL REACTOR TRIP DUE TO INADEQUATE FEEDWATER FLOW
"On October 29, 2018 at 1317 EDT, with St. Lucie Unit 1 in Mode 1 at 100% power, the reactor was manually tripped due to inadequate feedwater flow to both 1A and 1B Steam Generators (S/Gs). The trip was uncomplicated with all systems responding normally post-trip. [All control rods fully inserted and there were no specified system actuations.] Operators responded and stabilized the plant in Mode 3. The cause of the inadequate feed flow to the 1A and 1B Steam Generators is currently under investigation.
"Decay Heat removal is being accomplished through forced circulation with stable conditions from Main Feedwater and the Steam Bypass Control System to the Main Condenser. Currently maintaining Pressurizer pressure at 2250 psia and Reactor Coolant System temperature at 532 degrees F.
"St. Lucie Unit 2 was unaffected and remains in Mode 1 at 100% power.
"This report is submitted in accordance with 10CFR50.72(b)(2)(iv)(B) for the reactor trip.
"The NRC Senior Resident Inspector has been notified."

AGREEMENT STATE REPORT - DAMAGED GAUGE
The following information was excerpted from an email received from the State of Nevada:
On October 29, 2018 Round Mountain Gold Corporation reported a high wall failure that led to the collapse of an entire section of a mine. No one was hurt in the incident. The wall was being monitored for failure and the Mine Safety and Health Administration was at the mine two weeks ago. A Cs-137 fixed gauge of approximately 26.7 mCi was damaged in the incident. The gauge is in the unshielded position and cannot be recovered at this time due to industrial safety concerns.
