"On June 13, 2011 at 1924 CDT, an automatic reactor trip was actuated during Shutdown Bank Insertion for Beginning of Life Physics Testing. Neutron flux lowered from the intermediate range to the point of automatic energization of the Source Range Nuclear Instruments. Energization of the Source Range Nuclear Instruments during this step is anticipated and permissible per the test procedure. When it energized, the N-31 Source Range Nuclear Instrument (Red Channel) failed high which initiated an automatic reactor trip.
"All plant systems functioned as required, including the Reactor Protection System. All control rods fully inserted into the core. There was no Emergency Core Cooling System or Auxiliary Feedwater System actuation. No Emergency Diesel Generators were started and power continues to be supplied from off site. The reactor coolant system has forced circulation and the atmospheric steam dumps are currently being used for decay heat removal from the steam generators.
"There was no radiological release and emergency plan implementation was not required.
"An investigation of the failure of the N-31 Source Range Nuclear Instrument is in progress"
There is no known primary to secondary leakage. The licensee notified the NRC Resident Inspector.
* * * UPDATE FROM RUSS PARKER TO DONALD NORWOOD AT 2155 EDT ON 6/14/11 * * *
"At the time of the trip, the reactor was subcritical. This notification is updated to reflect reporting in accordance with 10CFR50.72(b)(3)(iv)(A).
"An investigation of the failure of the N-31 source range nuclear instrument continues."
This event was initially reported by the licensee as a four-hour report in accordance with 10CFR50.72(b)(2)(iv)(B).
The licensee notified the NRC Resident Inspector.
Notified R3DO (Kozak).
* * * UPDATE FROM ALEX RIVAS TO HUFFMAN ON 10/12/11 AT 1502 EDT * * *
'On June 14, 2011 at 2055 EDT, EN 46957 was amended to state the reactor was subcritical at the time of the trip. Subsequent review of this situation by the licensee resulted in a determination that at the time the test sequence was initiated, the reactor was critical and in MODE 2. Accordingly, this non-emergency report is amended to reflect EN 46957 as originally submitted on 06/13/11 at 2229 CDT. LER 301/2011-004-01 [submitted on July 25, 2011] will be revised accordingly.'
The licensee has notified the NRC Resident Inspector. R3DO (Peterson) notified. |

| Event Text 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.

"Automatic Reactor Trip due to Turbine Auto Stop Valve Closure and Actuation of Auxiliary Feedwater System.
"At 2328 on 10/11/2011, the reactor tripped due to a RPS actuation Signal from a turbine trip, which was caused by a Turbine Auto Stop signal. All control rods inserted on the trip, RCS pressure is currently 2235 psig and stable, and RCS average temperature is 547 degrees and stable. Decay heat removal is being controlled by auxiliary feedwater which auto started as expected and steam generator atmospheric relief valves. The licensee is investigating the cause of the Auto Stop Signal. The plant will be maintained in MODE 3 until the cause of trip is determined.
"The licensee has notified the NRC Resident Inspector."
There is no primary to secondary leakage. Offsite power is normal and all EDG's are available. | |
