AGREEMENT STATE REPORT - POTENTIAL OVER EXPOSURE OF RADIATION WORKERS
The following is a compilation of information received from a verbal report from the State of New Jersey; an e-mail from the State of California; and discussions with the RSO involved in the incident:
On October 8, 2011 at approximately 1000 EDT, three contractor personnel were loading Co-60 sources on a GammaCell 220 irradiator at a Johnson & Johnson facility located in Raritan, New Jersey. During the activity, an 8 inch 1210 Curie Co-60 source was somehow dislodged from its shielded position and approximately 4 inches of the source were exposed in an unshielded configuration. In addition, the insertion tool prevented the workers from re-inserting the source quickly. The workers were able to take a titanium shield and force the source into place by breaking off the insertion tool. The source was then confirmed to be in a shielded configuration and safely secured. The total time the source was exposed was estimated to be 25 to 30 seconds. The two individuals loading the source are employed by Foss Therapy, a California Agreement State licensed service provider. The third individual involved in the activity was the RSO employed by Gamma Irradiator Service (GIS) under a Pennsylvania Agreement State license. Based on readings from the electronic dosimetry being used by the workers, the two Foss Therapy employees are estimated to have received whole body doses of 8.1 R and 7.7 R respectively. The RSO working for GIS is estimated to have received a dose of 8.5 R. Extremity exposure has been estimated at between 50 R to 60 R for the two Foss Therapy workers. The workers were also wearing fresh TLDs and finger badging. More detailed dose information will be forthcoming after analysis of this dosimetry.

NOTIFICATION OF UNUSUAL EVENT DUE TO SEVERE ELECTRICAL FAULT IN RCP JUNCTION BOX
"Reactor Coolant Pump 2A tripped at approximately 1535 MST, resulting in numerous simultaneous electrical distribution alarms. A walkdown of containment was performed and at 1609 MST it was determined that a junction box, supplying power to the 2A Reactor Coolant Pump, had failed, resulting in the pump tripping on overcurrent protection and an 86 lockout. The plant was operating in forced circulation and had one train of shutdown cooling in service. As a result, an Emergency Classification of HU2.2, Explosion was declared due to the junction box failure and noise that had been heard in containment.
"The plant is currently stable with one train of shutdown cooling in service, the opposite train of shutdown cooling is available to be placed in service. The Unit 1 Reactor Coolant System is currently at 160 degrees Fahrenheit and 375 psia with the 1A Reactor coolant pump in service for forced circulation.
"The event did not result in the release of radioactivity to the environment and did not adversely affect the safe operation of the plant or health and safety of the public.
"The NRC Resident Inspector has been notified."
The licensee has notified appropriate state and local agencies.
* * * UPDATE FROM DAN DAILEY TO DONALD NORWOOD AT 2306 EDT ON 10/8/2011 * * *
The Notification of Unusual Event at Palo Verde Unit 1 was terminated at 1916 MST on 10/8/2011. The termination was based on conducting inspections which did not reveal any additional damage or plant impact as a result of this event. Unit 1 remains stable in Mode 5 with RCPs 1A and 1B in service along with one train of RHR in service. The licensee notified the NRC Resident Inspector and appropriate state and local agencies.
