UNUSUAL EVENT DUE TO FIRE IN THE PROTECTED AREA
"At 0346 CST [the Unit 1 control room] received a fire alarm in the plant computer room. Upon investigation [the licensee] discovered [the plant computer] room with heavy smoke present and the halon system actuated. [Plant operators] entered '0P0P04-ZO-0008, Fire and Explosion'. Entered Unusual Event at 0401 CST. Fire brigade present at Unit 1 electrical auxiliary building. At 0412 CST the fire was declared to be under control with no visible signs of flame noticed by the fire brigade. Unusual Event based on HU2 (fire or explosion) in the (Protected Area or Switchyard) which affects normal plant operations."
At 0446 CST the fire was declared to be extinguished. No plant equipment or indications were affected.
The licensee has notified the NRC Resident Inspector, the State of Texas, and other local authorities.

OFFSITE NOTIFICATION DUE TO DISCHARGE CANAL TEMPERATURE DROP
"At 0338 CST, Xcel Energy Environmental Services made a report to the State of Minnesota due to cooling water return to the Mississippi River via the plant's discharge canal dropping by more than 5 deg F per hour. The cause of the temperature drop was due to a required time limited reactor shut down. The reactor is currently shut down with all systems responding as expected.
"This notification is being made under 10 CFR 50.72(b)(2)(xi) based on a notification to another government agency.
"The NRC Resident Inspector has been notified"

REACTOR TRIP DUE TO TURBINE TRIP
"At 0840 [CST], Comanche Peak NPP [CPNPP] Unit 1 turbine tripped causing a reactor trip. All rods inserted. No evolutions were in progress at time of trip. The cause of the trip is under investigation. A Generator Negative Sequence Current High Alarm was received immediately prior to turbine trip.
"Both Motor Driven Auxiliary Feed Water Pumps and the Turbine Driven Auxiliary Feed Water Pump started in response to Steam Generator Lo-Lo Levels.
"Currently, Unit 1 is being maintained in Hot Standby (Mode 3) in accordance with Integrated Plant Operating Procedure IPO-007A and the Emergency Response Guideline Procedure Network has been exited. Decay heat is being rejected to the Main Condenser via Steam Dump Valves (Turbine Bypass Valves).
"Normal plant response was observed and all systems actuated as expected. No radiological release is in progress.
"There was no impact to CPNPP Unit 2, and off-site power remains available."
The licensee has notified the NRC Resident Inspector.

UNIT 2 PYRO PANEL NON-FUNCTIONAL DUE TO UNKNOWN EQUIPMENT PROBLEMS
"At 10:20 [CST] on January 18, 2014, the Unit 2 Pyro Panel (fire/smoke detection panel) was declared non-functional due to an unknown equipment problem. Compensatory measures (e.g. continuous roving fire watches) have been established for all affected areas with the exception of the Unit 2 Containment Building. Containment fire watches have been established per the FSAR, which includes monitoring various temperatures, pressures, and other parameters for Containment, and systems associated with containment. However, this is not considered a satisfactory compensatory measure for maintaining effective assessment capability. Since a fire in Containment is an entry condition for the site's Emergency Plan, this is considered a loss of emergency assessment capability, and is being reported per 10CFR50.72(b)(3)(xiii).
"The NRC Senior Resident Inspector has been informed."
* * * UPDATE FROM RICK LULLING TO DANIEL MILLS AT 0700 EST ON 1/20/14 * * *
"At 0404 CST on 1/20/14 the Unit 2 Pyro panel was declared functional following the replacement of the fire indicating unit (FIU) and the power supply, and successful post maintenance testing. The emergency assessment capability for the site's Emergency Plan has been fully restored concerning a Containment fire."
The licensee notified the NRC Resident Inspector.
