MANUAL REACTOR TRIP DUE TO FAILED REACTOR COOLANT PUMP POWER TRANSFER
"On May 4th, 2017, at 1709 EDT, Watts Bar Nuclear Plant Unit 1 reactor was manually tripped due to a failure of the #3 Reactor Coolant Pump normal feeder breaker to close during the planned power transfer to unit power following startup. Concurrent with the reactor trip, the Auxiliary Feedwater system actuated as designed.
"All Control and Shutdown rods fully inserted. All safety systems responded as designed. The unit is currently stable in Mode 3, with decay heat removal via Auxiliary Feedwater and Steam Generator Atmospheric Dump Valves. Unit 1 is in a normal shutdown electrical alignment.
"This reactor trip and system actuation is being reported under 10CFR 50.72(b)(3)(iv)(A) and 10CFR 50.72(b)(2)(iv)(B).
"There was no effect on WBN Unit 2.
"The NRC Senior Resident [Inspector] has been notified."

OFFSITE NOTIFICATION DUE TO MISCOMMUNICATION DURING ON-THE-JOB TRAINING
"On 5/4/17 at 2103 CDT, the South Texas Project [STP] Security Department was conducting on-the-job training for Bomb Threat response. While simulating the Bomb Threat Checklist via phone call, the trainer mistakenly contacted the Brazoria County, TX Child Protective Services (CPS) and reported a bomb threat. In response, the Child Protective Services notified the City of Brazoria, TX Police Department of the threat. The Brazoria Police Dept. then contacted both the Bay City, TX Police Department and the STP Security Department. By approximately 2130 CDT, all agencies had been notified by the STP Security Department of the mistaken phone call and that no actual bomb threat existed.
"The NRC Senior Resident Inspector was notified of the issue."
