FIXED GAUGE STUCK SHUTTER
The following was received from the State of Wisconsin via email:
"On Sunday November 8, 2015, the Wisconsin Radiation Protection Section received a phone call from the mill Radiation Safety Officer (RSO) for the Wisconsin Rapids facility that the licensee had a fixed gauge with a shutter stuck open. An alarm light on the panel indicated that the shutter was not closed. The operator notified the mill RSO who then contacted the corporate RSO. The RSO had Voith Paper, who is authorized for non-routine maintenance to come in to fix the shutter. He pulled the scanner offline around 2230 [CST] with the shutter stuck open. The manufacturer's representative was able to fix the shutter. The scanner went back online around 0030, Monday, November 09, 2015."

MANUAL REACTOR TRIP DUE TO REACTOR COOLANT PUMP OIL LEAK
During power ascension following refueling outage, a decreasing oil level in the 'C' Reactor Coolant Pump was noted. When the oil level reached 69 percent, with the reactor at approximately 56 percent rated thermal power, per plant procedure, a rapid downpower was initiated which brought the plant to approximately 15 percent power and a manual reactor trip was initiated at that point. The reactor trip was uncomplicated and all plant equipment responded as expected.
The licensee notified the NRC Resident Inspector.
