AGREEMENT STATE - UNATTENDED GAUGE DAMAGED BY BULLDOZER
The following was received via e-mail:
"On May 14, 2019, at approximately 1620 [EDT] Kentucky Transportation Cabinet, (KY RML# 201-086-51) reported that a Humboldt 5001 EZ, serial number 3133 moisture density gauge had been severely damaged and partially buried by a bulldozer, at a road construction project in Madison County located near Richmond KY. The gauge contained 0.37 GigaBq (10 milliCi) Cesium-137 (serial number 8273GQ) and 1.48 GigaBq (40 milliCi) Americium-24:Beryllium (serial number NJ03357). The technician had been taking some readings, while waiting for more rock to be put in place and put the device in safety mode and set it on top of pile of Dense Graded Aggregate. He then walked over about 80 feet to talk to an operator when it was run over by a bulldozer. KY Radiation Health Branch personnel were on the scene at approximately 1800 [EDT] and determined that the top of the source rod had been broken off and the outer case of the gauge was cracked. There was no leakage detected and the survey of the broken case showed readings = 10mR/hr on contact indicating that the shielding had not been compromised. The area was taped off in a 30 foot circle surrounding the damaged device till it was recovered by the Fayette County HAZMAT Team and placed into a 55 gallon drum, sealed and removed to a storage facility. The Radiation Safety Office indicated that a final decision on the disposition of the gauge will be forthcoming, and that retraining of the employee would be a priority, to include emphasis on surveillance and situational awareness at jobsites."

VOLTAGE TRANSIENT DUE TO LOSS OF OFFSITE SWITCHYARD
"At 2151 CDT, on 14 May 2019, Comanche Peak Nuclear Power Plant (CPNPP) experienced a voltage transient within the onsite 138kV switchyard due to the loss of one of the offsite switchyards supplying power to the CPNPP 138kV switchyard. The reduction in safeguards bus voltage due to the transient caused the Unit 2 safeguard busses to load shed and perform a slow transfer to power supplied from 345kV transformer XST2A. Unit 2 was subjected to actuation of both blackout sequencers causing an automatic start of both motor driven Auxiliary Feedwater (AFW) pumps as well as the turbine-driven AFW pump.
"No emergency diesel generators started by design. All AFW pumps have been returned to standby status. All other safety systems functioned as designed. Unit 1 is currently defueled, and was unaffected by this event.
"The licensee has notified the NRC resident inspector."

RADIOGRAPHY SOURCE STUCK IN EXPOSED POSITION
On May 14, 2019, at 1324 EDT the Radiation Safety Officer (RSO) was contacted by the Operation Manager and informed that a source located at a site in Muskegon MI could not be returned to the shielded position by the normal means. The technicians verified the boundary to ensure no unplanned exposure. The RSO called the site technician and went through the source retrieval procedure. The source was a SPEC model 150 camera with 89 Ci Ir-192 source. The RSO went to the site and was able to determine the location of the source and put temporary shielding on it. The RSO determined the source tubing was crimped and was able to straighten the tube. The source was retracted into the camera and locked by 1550 EDT. The crimped tubing was replaced with new tubing. The device was tested satisfactorily.
There were no over exposures. The doses received during the radiography and retrieval process were: RSO 28 mR, Radiography 23 mR, and Assistant Radiography3 mR.
