AUTOMATIC REACTOR SCRAM DUE TO TRANSFORMER SUDDEN PRESSURE RELAY ACTUATION
"At 1012 CDT on April 12, 2014, Dresden Unit 2 automatically scrammed on TR-2 sudden pressure relay actuation. All rods inserted to their full-in positions.
"Following the reactor scram, the 'A' reactor recirculation pump did not run back to minimum speed automatically. Operators took action to run the recirculation pump to minimum speed manually. All other systems operated as expected. Reactor vessel inventory and pressure are being maintained in automatic.
"The cause of the scram was due to a trip of the sudden pressure relay for Main Power Transformer 2. Troubleshooting is in progress to determine the cause [of the trip of the sudden pressure relay].
"This condition is being reported pursuant to 10 CFR 50.72(b)(2)(iv)(B), any event or condition that results in actuation of the reactor protection system (RPS) when the reactor is critical."
Normal offsite power remains available. There was no impact on Unit 3.
The NRC Resident Inspector has been informed.

MANUAL REACTOR TRIP DUE TO MAIN STEAM ISOLATION VALVE FAILING SHUT
"At 2008 EDT, Vogtle Unit One was manually tripped in response to loop 1 outboard Main Steam Isolation Valve failing shut. All systems operated correctly in response to the reactor trip. All control rods fully inserted. System response allowed for an uncomplicated reactor trip response. Unit 1 is stable in Mode 3 and cause investigation is in progress."
"The NRC Senior Resident Inspector was notified."
There was a normal post trip feedwater isolation due to low Tave.
Offsite power remains available. Decay heat is being removed by the main condenser. The plant is stable in Mode 3. There was no impact on Unit 2.

NEW JERSEY AGREEMENT STATE REPORT - RADIOACTIVE GAUGE SHUTTERS STUCK
The following information was obtained from the State of New Jersey via email:
"Event date and time: April 12, 2014 (time was not included in initial report)
"Event location: aboard dredge vessel M/V Glenn Edwards working in NJ waters near Long Branch, NJ
"Event type: Fixed gauges with stuck shutter
"Notifications: RSO notified NJDEP [New Jersey Department of Environmental Protection] staff in person on 4/14/2014 at approximately 0900 [EDT] during an inspection.
"Event Description: The M/V Glenn Edwards has three fixed gauges used to measure slurry density of dredged materials; one on the starboard arm, one on the port arm, and one on the bow of the dredge. The licensee reported that a survey and inspection of the gauges on 4/12/2014 revealed that two of the three gauges have shutter handles which are not functioning to move the internal shutter cylinder. The bow device (Berthold LB 7444-D-CR containing 100 mCi Co-60 at installation) appears to be stuck in the closed position. The starboard device (Berthold LB 7444-CR containing 500 mCi Co-60 at installation) appears to be stuck in the open position. The beam is oriented out to sea, away from any occupied space. The licensee reports that there is no exposure hazard to licensee personnel, crew or other members of the public. The licensee is contacting the device manufacturer to arrange for repair/disposal and has committed that a service provider would be contracted to perform the work.
"The event is reportable to NJDEP under N.J.A.C. [New Jersey Administrative Code] 7:28-51.1 (adoption of 10 CFR 30.50(b)(2)).
"NJDEP will continue to monitor the situation and provide updates as necessary. A notification was also made to the Florida Bureau of Radiation Control."
The operator of the dredge vessel is a licensee of Florida (Florida License #4019-1) working under reciprocity in the State of New Jersey.
