| Event Text AGREEMENT STATE REPORT - POTENTIAL SHALLOW DOSE EQUIVALENT OVEREXPOSURE
"On 1/26/10, the Agency [State of Texas] received a report from the licensee's Radiation Safety Officer stating they had received a report from their dosimetry processor indicating one of their workers had received 230 rem to the badge worn on his left hand. The right hand badge read 1.420 rem for the same period. The RSO stated that the individual involved handled predominantly Fluorine (F)-18. His deep dose equivalent (DDE) for the same period was 439 millirem. The RSO stated that the typical exposure to the hands is between 500 and 1,200 millirem and that the DDE was about 250 millirem per exposure period. The RSO believed the exposure was to his badge only. The RSO stated that on December 23, 2009, the individual was involved in a spill of F-18 and his badge may have become contaminated causing the exposure. The RSO stated that he was waiting on a statement from the individual involved.
"On February 25, 2010, the Agency received a written report of the event from the licensee. A review of the report indicated that the information provided did not appear to substantiate the conclusion made by the licensee that this was a badge only event. The Agency's position is that the actual shallow dose equivalent (SDE) is currently unknown, and may have exceeded the limit. The Agency has begun their investigation. Additional information will be provided as obtained."
Texas Incident Number I-8707

"It was determined that the individual was involved in a spill of F-18 and his badge became contaminated causing the exposure. It is believed that the worker contaminated his badge when he removed his gloves after cleaning up the spill. Surveys of the room after the spill indicated that the door handle used to exit the room by the individual was contaminated. The individual performed a contamination survey of his hands after leaving the room and they were not contaminated. Calculations indicate that, based on the specific activity of the F-18 involved, a small fraction of a milliliter would be required to cause this dose to the badge. The Agency agrees that this was a badge only exposure.
"This Agency is requesting that this event be retracted."

"On March 19, 2010 at 2350 hours, the Agency [Texas Department of State Health Services-Radiation Branch] was notified by the licensee's Radiation Safety Officer (RSO) that 120 milliCuries of Iridium (Ir)-192 was stolen from one of their trucks parked at a Wal-Mart parking lot in Alice, Texas at about 2320 hours. The Ir-192 was contained in six, 20 milliliter vials each containing 20 millicuries (15 grams) of Ir-192 in the form of zero wash [isotope tracer]. Each vial was placed into a labeled lead pig and each pig was then shrink wrapped. The six pigs were then placed into a zip lock bag. The zip lock bag was placed into a tool box in the back of the pick up truck. The licensee stated that the employee had stopped at the Wal-Mart on their way to a job site in south Texas. The RSO stated that the tool box was not locked and other items were stolen from the tool box. The tool box did not have any labeling on it. The RSO stated that the employee did not perform a radiation survey of the pigs, but he estimated the dose rate to be about 100 millirem per hour on the outside of the tool box. Local law enforcement was notified of the theft. Additional information will be provided as it is received."

The following information was obtained from the State of Colorado via facsimile:
"The Department received notification on March 23, 2010, of a fetal exposure in excess of 500 milliRem from a PET/CT Scan. The licensee, PET Imaging of Northern Colorado, License No. 1105-0, is located in Fort Collins, Colorado. The licensee reported that on December 14, 2009, a female patient received 17.4 mCi of F-18 and underwent a PET/CT scan. The patient had indicated that she was not pregnant on her medical history questionnaire and told the technologist she was not pregnant prior to the scan. Later, the patient's physician notified the licensee that the patient was indeed pregnant at the time of the scan.
"A consulting medical physicist calculated the total dose to the fetus from the PET/CT scan as 2.6 Rem (26 mGy). However, the medical physicist did not report the individual dose from the F-18 component alone, and this information has been requested from the licensee.
"The licensee's authorized user physician reported that the risk of abnormality for the fetus is considered to be negligible per the guidance from the American College of Radiology Practice Guidelines.
"No other details are available at this time." |

"At 2255 [EDT] on 3/25/2010, a Demister Door on 'B' Train of Standby Gas Treatment (SBGT) was found open. The door was closed upon discovery. The door was opened during performance of a scheduled surveillance during the dayshift and it appears that the door was not closed at the completion of work. With this door being open the 'B' Train of SBGT was INOP. Due to the physical configuration of the SBGT System it cannot be immediately verified that the 'A' Train of SBGT would have been able to perform its Safety Related Function since there is a probability that it could have drawn suction through the demister door of the 'B' Train and a normally open crosstie between the Trains. A 10 CFR 50.72 notification is conservatively being made based on the information currently available.

"At approximately 1852 hours Eastern Daylight Time [EDT], on March 28, 2010, with the unit operating at approximately 99.5% power, the H. B. Robinson Steam Electric Plant, Unit No. 2, reactor protection system actuated resulting in an automatic trip of the reactor. At about the time of the reactor trip, there was indication of a loss of the power to the Train 'B' emergency bus. The Train 'B' Emergency Diesel Generator started and provided power to the Train 'B' emergency bus. The Reactor Coolant System pressure response after the reactor trip resulted in the actuation of the Safety Injection System. The reduction in Reactor Coolant System pressure allowed the safety injection system to provide flow to the reactor coolant system, although, there was no indication of conditions that would require the safety injection system to provide flow to the reactor coolant system. Specifically, diagnosis of the event determined that a loss of coolant event, steam generator tube rupture, or secondary system break were not occurring. The safety systems that actuated for this event included the Reactor Protection System, the Safety Injection System, both Emergency Diesel Generators started and the 'B' Emergency Diesel Generator provided power to the 'B' Train Emergency Bus, the Auxiliary Feedwater System actuated, and the three main steam isolation valves closed. The Steam Generator Power Operated Relief Valves are being used for decay heat removal because of the closure of the main steam isolation valves. The Startup Transformer is energized and providing power to the 'A' Train Emergency Bus. Investigation of the cause of the reactor trip and associated emergency system actuations is in progress. At the time of the event, it was noted that there was evidence of a fire condition at 4KV bus number 5 located in the Turbine Building. It is currently believed that this is the cause of the transient condition that resulted in the reactor trip and other emergency system actuations. The reactor is currently being maintained in MODE 3, Hot Standby, conditions."
"This event is being reported in accordance with 10 CFR 50.72(b)(2)(iv)(A) for ECCS discharge into the RCS and (B) for RPS actuation, and 10 CFR 50.72(b)(3)(iv)(A) for specified system actuation as described.
"Additionally, based on an inquiry from the local news media reporter, information regarding this event was discussed with the local media. This contact with the local news media is being reported in accordance with 10 CFR 50.72(b)(2)(xi)."
All control rods fully inserted on the trip. Volume Control Tank [VCT] level was not dropping consistent with no reactor coolant system leakage. Pressurizer level and pressure drop was indicative of shrink associated with the Reactor Coolant Pump stoppage and cooldown in one loop. The licensee observed no indication of reactor coolant system leakage from the containment sump water level monitors.
The licensee informed the NRC Resident Inspector.
* * * UPDATE AT 2340 EDT ON 03/28/10 FROM MIKE DONITHAN TO PETE SNYDER * * *
The original Non-Emergency classification was reclassified as an ALERT based on the following:
"A fire on 4kV Bus 5 affected 4kV Bus 4 which caused a loss of 'B' Reactor Coolant Pump which caused a Reactor trip and Turbine Trip.
"That fire was extinguished without a required event declaration, but a subsequent fire on 4kV Bus 4 required declaration of an ALERT at 2300 [EDT] based on the fire affecting the safety-related 'A' and 'B' DC Buses. The fire was out at 2301 [EDT].
"The primary systems are available and control of the Reactor Coolant System has been maintained. The Safety Injection termination Emergency Operating Procedure has been performed and the general procedure for post-trip stabilization is being performed."
