AUTOMATIC REACTOR SCRAM
"A reactor SCRAM occurred at 1856 CST on 2/7/15 from 100 percent core thermal power. The cause of the SCRAM appears to be a Generator/Turbine trip, but it is still under investigation.
"Appropriate off-normal event procedures were entered to mitigate the transient with all systems responding as designed. No loss of offsite or ESF power occurred. No ECCS initiation signals were reached, and no ECCS or Emergency Diesel Generator initiations occurred.
"Main Steam Isolation Valves remained open and Safety Relief Valves lifted and reseated as designed. Currently, reactor water level is being maintained by the Condensate and Feedwater system in normal band, and reactor pressure is being controlled via turbine bypass valves to the main condenser."
Following the reactor SCRAM, all rods fully inserted and all systems functioned as expected. The plant is in a normal electrical lineup.
The licensee has notified the NRC Resident Inspector.

OFFSITE NOTIFICATION TO OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION (OSHA)
"At approximately 0848 [EST] on February 7, 2015, a contract employee was found unresponsive at a VC Summer Unit 1 facility outside the Owner Controlled Area. The VC Summer Medical Emergency Response Team responded to the scene and provided assistance until offsite medical personnel arrived. Emergency Medical Services arrived on the scene and transported the individual to a local area hospital. VC Summer has reported this to OSHA and is reporting this to the NRC in accordance with 10 CFR 50.72 (b)(2)(xi).
"The NRC Resident Inspector has been notified."
* * * UPDATE AT 1300 EST ON 02/16/15 FROM MICHAEL MOORE TO S. SANDIN * * *
"At 0935 EST, on February 16, 2015 SCE&G notified OSHA that the contract employee had passed away. This update also corrects the second sentence of the initial notification that station personnel versus the Medical Emergency Response Team responded to the scene.
"The NRC Resident Inspector has been notified."
Notified R2DO (Nease).
