"At 1500 [CDT], a concern was raised with regard to scaffolding that had been constructed around safety related equipment in the Auxiliary Building which contains both trains of safety injection and containment spray. As a result T.S. 2.0.1 was entered (which is the Fort Calhoun equivalent to standard T.S. 3.0.3). The scaffolding in question was removed and the equipment was returned to operable status and T.S. 2.0.1 was exited at 1726 [CDT]."

The following was received via e-mail:
"The patient underwent a permanent seed prostate implant in the UCLA 200 Medical Plaza outpatient surgery suite on 4/4/2011. The patient returned to the UCLA Department of Radiation Oncology on 5/3/2011 for a follow-up visit and a post-implant CT scan. A post-implant treatment plan was performed to verify seed placement and final dosimetry endpoints. The post-implant dosimetry plan indicated a significant number of seeds were implanted outside of the prostate.
"A detailed dosimetry analysis is being performed but is unavailable at the time of this report. This report will provide the details of the intended dose versus the received dose, as well as other supplemental information. This report will be included in the final investigation packet.
"UCLA has notified CDPH RHB [California Department of Public Health Radiologic Health Branch] that the permanent seed implant program has been placed on temporary hold pending review of this procedure. No further procedures have been performed since this discovery.
"This investigation is ongoing."

The following information was received via email:
"Event Location: Flint Hills Resources LP, 2825 Suntide Road, Corpus Christi, Texas 78403.
"On May 24, 2011, the agency [State of Texas] was notified by a licensee that they were unable to retract a 27.7 Curie iridium (Ir) - 192 radiography source into a QSA Delta 880 camera at a field site. The licensee stated that when setting up for a shot, the radiographer ran the crank cables for the camera over a hot pipe. The licensee stated that while conducting a shot, the plastic on the crank cable shield melted. The licensee believes that this may have prevented the radiographer from retracting the source to the fully shielded position. The licensee's source recovery team went to the location and was able to return the source to the fully shielded position. The camera was taken to the licensee's facility for inspection. No one involved in the source recover exceeded any regulatory limits. The investigation into this event is on going. Additional information will be provided as it is received."

The following information was received via email:
"While using a QSA Global 880D radiographic exposure device, the licensee's crew was unable to move the drive cable forward or backward. It appeared that the source was moved slightly out of the fully shielded position when the device was unlocked prior to the attempt to crank out the source. The crew was unable to retract the source and lock the device. A licensee employee trained in source retrieval was sent to the site. The employee disassembled a portion of the drive cable which gave him access to manually pull the drive cable in the direction that would retract the source. The cable was moved approximately 1/4 inch. This placed the source in the fully shielded position and the source was locked in the shielded position.
"Only licensee personnel were potentially exposed to radiation from the device during the incident. Licensee personnel stated that they did not step in front of the camera at any point during the incident. The radiographer used the survey meter to determine where to stand to receive the least exposure while checking the camera. At one point he reached forward with the survey meter and measured 200 mR/hr at the front port of the device. Dose estimates for licensee personnel associated in the incident were well below the limits for occupationally exposed individuals."

"[On] 4/23/10, Dominion Resources called to inform [New York State Department of Health] that one tritium exit sign was found missing after some demolition work at their Utica, NY facility. A written report [was] received [on] 4/29/10.
"During a company wide effort to inventory all tritium exit signs it was discovered that one was missing at their Utica facility. An investigation ensued, and it was determined that during July of 2009, the entire wall on which the exit sign was located was removed during remodeling. The exit sign was likely disposed of in a 30 cubic yard roll-off container owned by Waste Management and is likely in the local AVA landfill. Dominion is reinforcing and enhancing established processes and programs for handling tritium exit signs. This event will be incorporated into training and lessons learned. All other signs at the facility are accounted for, [and] this incident is closed."

The following information was received via fax:
"Event location: 14 Parker Hall, 3435 Main Street, Buffalo, NY, 14214
"The RSO at [SUNY at Buffalo] called on 08/21/08 to report a leaking nickel 63 sealed source located in a HP gas chromatograph unit. Location of unit is Farber Hall room 2128. Apparently on Monday, August 11, 2008, the researcher was cooking 'stuff' in the oven portion of the unit. Product exploded in the oven and spilled over into the other parts of the unit and landed on the sealed source compromising integrity. Contamination was found in the oven of the unit. SUNY EH&S [State University of New York Environment, Health and Safety] staff performed decontamination of the unit until <100 dpm. No contamination was found outside of the unit. SUNY EH&S staff also surveyed the rooftop of the building as the unit is vented and no contamination was found. SUNY EH&S [gave] the researcher until Friday, 08/29/08 to submit his report of the incident to EH&S. NYS staff visited [SUNY at Buffalo] on 08/26/08 and interview [an individual] who reported that the leak was found during the routine leak testing. When the swipe came back high, he re-swiped the unit and noticed a white powder all over the oven and inside the tubing. [When] asked, the researcher stated that she had dried a silica gel in the oven on 08/11/08. Apparently, the foil cover blew off of the beaker, and the silica gel went all through the machine via an inlet port possibly 'sandblasting' the foil compromising its integrity. Swipe testing by liquid scintillation showed contamination on inlet and outlet and no contamination on the housing or outside the machine. EH&S has decontaminated the machine as much as possible and taken it out of service. EH&S has also contacted the manufacturer of HP 5890. Manufacturer states there is no way to clean it and the machine should be scrapped. EH&S plans to take out the source, scrap metal parts that are not contaminated and hold remaining pieces until a disposal option is available. Written report [was] received [on] 9/11/2008 .
"The unit [is] to be handled as indicated above, and additionally, all researchers will be in-serviced on keeping the inlet to the foil capped when using ovens for other than GC [gas chromatograph] analysis. Incident is closed."

The following information was received via email:
"At approximately 3:30 p.m. on Wednesday, May 25, 2011, the radiation safety officer (RSO) of Nuclear Diagnostic Products of Philadelphia called to inform the [New Jersey Department of Environmental Protection's Radioactive Materials Program] NJDEPs RMP that a sealed rod source containing approximately 2.68 microCuries of cobalt-57 was unaccounted for at their facility. The source had been returned to the licensee by one of their customers for disposal. The source was secured at their location prior to being shipped for final disposal. In the interim, the room where the source was being secured was painted and materials were moved to a different room while the painting activities occurred. The painting activities began about three weeks ago.
"When the removed materials were returned to the room after the painting was concluded recently, the source could not be found. A search was conducted by the licensee, but, to date, the source cannot be located. The licensee believes the box that contained the source was either inadvertently placed in the garbage for routine disposal or the source was placed into a sharps container for incineration with biohazard materials. The licensee will continue to look, but informed us of the matter after what they believe is a comprehensive search."

The following information was provided by the State of Texas via email:
"On May 26, 2011, the Agency [Texas Department of Health] was notified during routine inspections of the facility's site safety systems, it was discovered that two tritium exit signs were missing from their fixed mounting positions. These signs were affixed to the walls near exits in a secure manner such that they could only be removed by means of removing safety capped mounting screws and then the use of tools to remove them. In this case, it is apparent that these signs were removed by way of vandalism and were essentially pulled off the walls leaving evidence that they were removed without the knowledge of the site personnel. A report was made to the local police department. The signs were installed new in 2010.
"In addition, this same vandalistic act occurred at the same location as reported to the Agency [Texas Department of Health] on February 2, 2011. At that time, four tritium exit signs were removed. A report was made to local law enforcement. The exit signs are Isolite Model 2040-95S-B-15-WS, and each contain 9.5 Curies of tritium."

If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10CFR50.73.
"This report is being made under 10 CFR 50.73 (a) (2) (iv) (A) for a reportable invalid actuation.
"On April 3, 2011, at approximately 1444 Mountain Standard Time, Palo Verde Nuclear Generating Station Unit 2 experienced an invalid actuation (start) of the 'A' Emergency Diesel Generator (EDG). EDG 'A' inadvertently started during integrated safeguards surveillance testing to demonstrate that the EDG overspeed trip is not bypassed. Prior to the test, the EDG overspeed governor was actuated, but the butterfly valve was not verified to be fully closed as required. The valve closure actuates a limit switch which activates the interlock that prevents the EDG start following an overspeed trip. The test requires the operator to ensure the butterfly valve is fully closed because it may not fully close as the EDG is not running when it is actuated for the overspeed test.
"When the demand signal was inserted, the EDG started unexpectedly since the butterfly valve was not fully closed and the limit switch was not engaged. EDG 'A' Train completely actuated in the Emergency Mode and the EDG came up to rated speed and voltage as designed. The supporting 'A' train Essential Spray Pond System, used for engine cooling, was already running prior to the test. The Essential 'A' Train EDG Exhaust Room air handling unit started as required.
"No damage occurred to the EDG or related equipment as a result of the unplanned actuation. The EDG was secured and the test was successfully re-performed.

"On May 27, 2011, at 1212 PDT, Unit 1 startup power was lost due to actuation of startup transformer 1-1 overcurrent/differential relay 51-87UT11-1, which isolated the 12 kV feeder to startup bus. The loss of offsite startup power caused all Unit 1 emergency diesel generators (EDGs) to start in the standby mode. The EDGs started as designed with no issues observed. No vital loads were affected as a result of the 12 kV bus loss. On May 27, 2011, at 1241 PDT, all Unit 1 EDGs were shut down and returned to auto. Subsequently, startup transformers 1-1 and 1-2 were energized, followed by the 12 kV underground loop, and on May 27, 2011, at 1337 PDT, Unit 1 startup power was declared operable.
"The cause of the event was a human performance error while attempting to test the startup transformer 2-1 overcurrent/differential relay. The maintenance electrical worker inadvertently installed a jumper on the overcurrent/differential relay for startup transformer 1-1.
"Unit 2 startup power was cleared at this time and there was no effect on Unit 2.
"The NRC Resident Inspector was notified." |

"Surry Unit 2 is in Intermediate Shutdown and was supplying steam generators with a main feed pump. The second main feed pump is tagged out for maintenance. The running main feed pump exhibited a low oil flow condition. The operating team took the deliberate action to secure the running main feed pump to prevent bearing damage with the knowledge that an Auxiliary Feedwater actuation signal would be generated. The plant was realigned to flow to the steam generators with the condensate pumps and the auxiliary feed pumps were then secured [at] 0821.
"This notification is being made pursuant to 10 CFR 50.72(b)(3)(iv)(A) for 8-hour notification of automatic actuation of AFW. Plant responded as expected. The NRC Resident Inspector has been notified of this event and is on site.
"There were no radiation releases due to this event, nor were there any personnel injuries or contamination events."
Offsite power is normal and emergency diesel generators are operable and available. There was no increase in plant risk as a result of this event. |
