The following information was received from the State of Texas via email:
"On February 20, 2015, the Agency [Texas Department of State Health Services] was notified by the licensee that on February 19, 2015, one of its radiography crews working at a remote field site [near Kennedy, Texas] was unable to retract a 31.9 Curie Iridium 192 source into a QSA 880D exposure device. The radiographers were examining a pipe on a pipe pad with the collimator being held in place with a magnetic stand. As the radiographer began to retract the source after a shot, the stand fell and struck the source guide tube crimping the tube to a point where the source could not be moved. The radiographers stopped work in the area and moved their boundaries to prevent exposures to members of the general public. The radiographers contacted their radiation safety officer (RSO), but he was located 8 hours from the work site. The RSO contacted the licensee's office in Corpus Christi, Texas and the RSO from that location responded to the event. The Corpus Christi RSO is [at the location] to perform source retrieval. The event occurred at 1630 [CST] and the source was retracted at 2400 [CST]. No over exposures occurred and no member of the general public received any additional exposure from this event. The guide tube has been removed from service for inspection. The dosimetry badges for the individuals involved in the event have been sent to the licensee's processor for reading. The licensee is investigating the event. Additional information will be provided as it is received in accordance with SA-300.
"On February 20, 2015, the licensee agreed to send the source involved in this event to the manufacturer for inspection."

The following information was received from the State of Wisconsin via email:
"The Wisconsin Radiation Protection Section received notice from the licensee's Corporate Radiation Safety Officer (RSO) that a radiography crew working at a temporary jobsite on February 23, 2015 had a source become stuck during radiography operations. The crew was using an Ir-192 source in a QSA Global 880 Delta camera. While the source was cranked out in the collimator, a pipe fell on the guide tube and crimped the tube such that the radiographers were unable to retract the source. Two radiographers who are trained in source retrieval were dispatched to the jobsite. They cut out a one-inch section of the guide tube and were able to retract the source into the camera. As indicated by pocket dosimeters, radiation doses received by the radiographers were beneath regulatory limits.
"The Wisconsin Radiation Protection Section will follow up with the licensee after receiving its 30-day written report. Additional updates will be provided through NMED."
The licensee is sending the camera drive cable to the manufacturer for evaluation and has disposed of the damaged guide tube.

"At 06:45 EST on 3/2/2015, Sequoyah Unit 2 reactor/turbine automatically tripped.
"Following the reactor trip, all safety-related equipment operated as designed. Auxiliary Feedwater automatically initiated as expected from the Feedwater Isolation Signal.
"Unit 2 is currently being maintained in Mode 3 at NOT/NOP [normal operating temperature and pressure], approximately 548 F and 2235 psig, with auxiliary feedwater supplying decay heat removal via the steam generators and condenser steam dumps.
"The immediate cause of the trip was a main generator C phase differential relay actuation. There was no associated work in progress related to this and all systems were normally aligned. It is currently not understood why the relay actuated.
"Current Temperature and Pressure - temperature is 548 degrees F and stable, pressure is 2235 psig and stable. There is no indication of any primary/secondary leakage. All rods are inserted. Electrical alignment is normal, supplied from Off-Site power. The 2B Emergency Diesel Generator is currently unavailable for planned maintenance and will be returned to service prior to unit restart. There is no operational impact to Unit 1. Unit 1 continues to operate in Mode 1 at 100%.
"There was no impact on public health and safety. Post-trip investigation is in progress and planned restart timeline has not yet been determined.
"The licensee notified the NRC Resident Inspector" and the state.
No primary or secondary safety valves lifted during this event. |
