| Event Text AGREEMENT STATE REPORT - STUCK RADIOGRAPHY SOURCE
A representative from the State of Kansas contacted the NRC Operations Center to report a stuck radiography source. The source is stuck at Chanute Manufacturing Shop, 1700 South Washington Street, Chanute, Kansas. The company has a radiography shop and was performing a radiography shot of a drum when the guide tube stand fell approximately 2 feet and kinked the guide tube while retracting the source. The camera is an Amersham Model 880 with less than 100 Curies of Ir-192. The licensee reports the source is "stuck good". A 1 Mr/hr boundary has been established, and the area is secured. The state is unsure how far the source is from its fully retracted storage location. The licensee is attempting to locate a recovery team, and the State of Kansas is requesting assistance in locating a recovery team.
At 1110 EDT, the State of Kansas called back to report that the licensee has made arrangements with QSA Global of Boston, MA to come to the site today and recover the source.
* * * UPDATE ON 08/27/07 AT 1034 EDT FROM DAVID WHITFILL TO MACKINNON * * *
QSA arrived on 08/25/07 and completed recovery operations at 2017 CDT on 08/25/07. Highest dose received by a QSA person during recovery operations was 50 millirems as measured by an ion chamber detector.
R4DO (R. Nease) and FSME (C. Flannery) notified. |

"At 13:54 on 8/28/07, DC Cook Unit 1 experienced an automatic reactor trip due to low steam generator water level coincident with low feedwater flow on #11 steam generator. The cause was a malfunction of the Main Feedwater Pump Digital Control System, which remains under investigation. This requires a 4-hour report under 10CFR50.72(b)(2)(iv)(B).
"Both Motor-Driven Auxiliary Feedwater Pumps automatically started due to the reactor trip. The Turbine-Driven Auxiliary Feedwater Pump (TDAFP) started automatically due to low-low water levels in at least two steam generators, which is expected for a reactor trip from 100% power. The automatic actuation of the reactor protection system and the TDAFP start require an 8-hour report under 10CFR50.72(b)(3)(iv)(A).
"All systems functioned as expected after the trip, and no major components were out of service at the time of the trip. This is a non-complicated trip.
"The NRC resident has been notified."
The reactor tripped at 15% steam generator level and then level went off scale low as expected. All control rods fully inserted. No primary or secondary safeties or relief valves lifted with the exception of a feed heater relief valve. The plant is feeding steam generators with the motor driven auxiliary feed water pumps and dumping decay heat to the main condenser. The plant is in the normal shutdown electrical lineup. | |
