AGREEMENT STATE REPORT - STUCK PROCESS GAUGE SHUTTER

The following information was received via e-mail:

"On Sunday, June 8th, 2014, the Wisconsin Radiation Protection Section received notice from the mill [NewPage Wisconsin Systems] Radiation Safety Officer (RSO) for the Wisconsin Rapids facility that the licensee had a gauge with a stuck shutter. The stuck shutter was discovered on Saturday, June 7th at 5:00 pm [CDT]. The device is an Ohmart model A-2102 (serial number M-3212) fixed gauge originally containing 100 mCi of Cs-137. The facility is currently shut down for maintenance. VEGA Americas, Inc. has been called for immediate repairs. The mill RSO stated that the gauge was in the normal operating position and did not pose a radiation safety hazard. The gauge has been roped off from personnel. Personnel are not allowed inside the chip chute since it is in the path of the radiation beam between the broken source and its detector.

"The Wisconsin Radiation Protection Section will continue to monitor the situation."

The licensee reported the gauge shutter closed and they locked the shutter in the closed position. The licensee stated the manufacturer had been contacted and would be at the facility on the morning of June 6, 2014. The RSO stated he would provide additional information as soon as he could.

TECHNICAL SPECIFICATION SHUTDOWN DUE TO LOSS OF A AND B CONTROL BAY CHILLER TRAINS

"At 1729 [CDT] on June 17, 2014 Browns Ferry Units 1, 2, and 3 initiated actions to commence a reactor shutdown to comply with TS LCO [Technical Specifications Limiting Condition of Operation] 3.0.3. TS LCO 3.0.3 was entered at 1632 and was required due to the concurrent loss of 'A' and 'B' Control Bay Chiller units which resulted in loss of cooling to the U1 and U2 4kV Shutdown Board Rooms. Required actions for the loss of cooling to the U1 and U2 4kV Shutdown Board Rooms is to declare the electrical equipment in the 4kV Shutdown Board Rooms inoperable. The declaration of inoperability of the equipment supported by the U1 and U2 4kV Shutdown Boards resulted in TS LCO 3.0.3 for Units 1, 2 and 3. TS LCO 3.0.3 requires actions to be initiated within one hour to place the units in MODE 2 within 10 hours; MODE 3 within 13 hours; and MODE 4 within 37 hours.

"This event requires a 4 hour report IAW 50.72(b)(2)(i), 'The initiation of any nuclear plant shutdown required by the plant's Technical Specifications.'

"The NRC Resident Inspector has been notified.

"Service Request 899734 was initiated in the Corrective Action Program."

The 'B' Control Bay Chiller train was operating when the control room entered the Loss of Chilling procedure. The 'A' Control Bay Chiller train was started to supply Control Bay cooling, and the 'A' train unit tripped during start.

The failure affected unit-3 because each unit has a 50% capacity common standby gas treatment system. The loss of the the U1 and U2 4kV shutdown boards failed two of the three systems.

* * * UPDATE PROVIDED BY TODD BOHANAN TO JEFF ROTTON AT 2154 EDT ON 06/17/2014 * * *

"'A' Control Bay Chiller declared operable at 2035 CDT. TS LCO 3.0.3 exited and plant shutdowns have been secured."

The licensee will be notifying the NRC Resident Inspector. Notified R2DO (Haag)
