TECHNICAL SPECIFICATION REQUIRED SHUTDOWN
"The 1B and 2B trains of Nuclear Service Water Systems (Raw Water Nuclear RN) were declared inoperable on 1/18/11 at 0423 EST due to fouling of the respective suction strainers when aligned to the Standby Nuclear Service Water Pond (SNSWP).
"Tech. Spec. 3.0.3 was entered at 1110 EST on 1/20/11 due to the lack of reasonable assurance of operability pertaining to 1A and 2A RN trains in the event of a potential realignment to the SNSWP due to a seismic event."
The licensee plans to reduce power and place both Units in Mode 5. Unit 1 has been reduced to 90% and Unit 2 is holding at 100% and will begin reducing power later. The fouling is being caused by fish being sucked into the RN train suction strainers. The licensee has been back-flushing the strainers to clear the fouling. The pond was chemically treated approximately 1 year ago to eliminate the fish.
The licensee notified the NRC Resident Inspector.
* * * UPDATE FROM TERESA PUTNAM TO JOHN KNOKE AT 1313 EST ON 01/21/11 * * *
McGuire Units 1 & 2 entered Technical Specification 3.0.3 with a requirement to be in Mode 5 in 37 hours. A Notification of Enforcement Discretion was verbally approved by the Nuclear Regulatory Commission on 1/20/11 at 2336 EST, therefore both Unit 1 & 2 will remain in Mode 3.
The licensee notified the NRC Resident Inspector. Notified R2DO (Sykes), NRR EO (Thomas), and IRD MOC (Gott)

MANUAL REACTOR TRIP DUE TO LOSS OF BOTH MAIN FEED PUMPS DURING SHUTDOWN
"Unit 1 performed a manual reactor trip (from 28% power) due to the trip of the 1B main feedwater pump trip concurrent with the 1A main feedwater pump having been previously tripped per the shutdown procedure. Reactor power was below the setpoint for an automatic reactor trip from a turbine trip."
All rods fully inserted, heat removal is from auxiliary feedwater and condenser steam dumps, and the electrical system is in a normal alignment. The plant has stabilized at normal RCS pressure and temperature.
Both Units 1 and 2 are being shutdown as per Tech Spec 3.0.3 associated with an inoperable Nuclear Service Water System. Unit 2 is at 40% and decreasing power due to the Tech Spec action and was not effected by the Unit 1 reactor trip. Both units will be placed in Mode 5.
The licensee has notified the NRC Resident Inspector.

AGREEMENT STATE REPORT - DAMAGED RADIOGRAPHY CAMERA
The following information was provided by the State of Texas via email:
"On January 20, 2010, the Agency (State of Texas) was notified by the licensee that while performing radiography operations at a field location, a radiography camera containing 29 curies of Iridium 192 fell approximately six feet to a concrete surface. The radiographer attempted to retract the source, but it would not move out of the collimator. The locking device on the camera appeared to be damaged and was restricting movement of the drive cable. The radiographer worked on the locking device and was able to retract the source after a period of about 10 minutes. The front source stop was installed to prevent the source from moving from the shielded position. The maximum dose rate taken on contact of the camera was 32 millirem after the event. The survey done on the camera prior to starting work that day was 19 millirem. The radiographer could not disconnect the drive cable from the source pig-tail due to the damage to the locking device. The camera was transported to the licensee's facility for further action. The licensee contacted the manufacturer and with their assistance, was able to disconnect the drive cable from the source pig tail. The rear dust cover was placed on the camera, and both covers secured in place using tape. The camera will be returned to the manufacturer for inspection and repair.
"The total exposure received in this event was less than three millirem. Additional information will be provided as it is received."
