| Event Text AGREEMENT STATE REPORT - BROKEN I-125 SEED DURING IMPLANTATION
The following information was received from the State of Maryland via email:
"This is a synopsis of an I-125 seed breaking during an implant procedure at GBMC [Greater Baltimore Medical Center]. We [GMBC] will be meeting as a team to discuss corrective action and how to avoid something like this happening again.
"An I-125 implant was performed at GBMC Hospital on Tuesday, April 1, 2014. 78 Bard I-125 seeds, activity 0.319 mCi/seed, were ordered for the procedure, 71 seeds were used, and 70 seeds were confirmed after the procedure on CT evaluation in Radiation Oncology. The unused seeds (7.5 seeds) were returned to Radiation Oncology and recorded as per policy and procedure.
"The chief physicist and dosimetrist were called to Cysto at approximately 0900 EDT when the case was completed to [the attending physician's] satisfaction. Upon entry of the Cysto room [the attending physician] informed the physics staff that a seed had jammed in the Mick applicator and he had to use force to continue and complete the case.
"On arrival, the physics staff surveyed the patient 1 meter above the umbilicus and found 1.7 mR/hr reading using Model 14C Geiger counter (Serial number 167038, Calibration date 1/30/14). The patient was removed from the OR and sent to recovery room.
"Upon additional survey of the room, it was discovered that a seed was fractured, when a portion of the seed was found on the sterile table. At that time, a thorough and complete area survey was performed. The reading was found to be 1.2 mR/hour on the table, trash, and blood drain. [A staff member] was called to bring an additional survey meter (Model 3 Geiger counter Serial number 39484, Calibration date 4/29/13). All contaminated items were collected for proper storage in the hot lab in Radiation Oncology. All staff and personnel involved in the case were thoroughly monitored and cleared using 14C Geiger counter (Serial number 167038, Calibration date 1/30/14). After the removal of the contaminated items the Cysto room was thoroughly monitored and clear of radiation contamination.
"The patient was then brought down to the Radiation Oncology department where a CT scan was performed to ensure seed count. VeriSeed program was used to confirm that the patient was implanted with 70 seeds.
"[The Chief Medical Physicist] contacted Bard to discuss the shattered seed. It was suggested that radiation oncology staff be monitored for thyroid uptake. Bioassay studies were thereby performed and the results were found to match background readings.
"On Wednesday, April 2, 2014, the patient's recovery area was scanned using Model 3 Geiger counter Serial number 39484, Calibration date 4/29/13. A reading of 300 CPM was recorded. The background was also recorded to be 300 CPM. " |

"Pursuant to 10 CFR Part 21, section 21.21(b), Rosemount Nuclear Instruments, Inc. (RNII) is writing to inform you that certain Model 1154HP transmitters with integral 1159 Remote Diaphragm Seals may exhibit degraded functional reliability.
"The standard maximum working pressure for Model 1154 transmitters with integral 1159 Remote Diaphragm Seals is 2000 psi.
"Per the unique requirements of Point Beach Nuclear Generating Station, Model 1154HP5RAGN0080 pressure transmitters with integral 1159A50AS0111 Remote Diaphragm Seals were manufactured to operate at a non-standard maximum working pressure of 2750 psi.
"Once installed in the field, two transmitters exhibited unexpected drift in the output signal when operated at line pressures of approximately 2235 psi.
"To date there are no known additional reported functional reliability issues with other Model 115x Series transmitters with integral 1159 Remote Diaphragm Seals in a similar configuration.
"RNII does not have complete information relating to specific plant applications and therefore cannot determine the potential effects of the condition on plant operation.
"This notification affects seven Model 1154HP transmitters with integral 1159 Remote Diaphragm Seals shipped to Point Beach Nuclear Generating Station since March 2013."

"The following event description is based on information currently available. 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 10 CFR 50.73.
"This notification describes a previously undeclared event that is now reported pursuant to the requirements of 10 CFR 50.72(a)(3). No emergency situation exists at this time.
"On November 6, 2013, while operating at 100% reactor power under steady state conditions, a U-1 control room alarm was received indicating low fluid pressure in the Train 'A' hydraulic accumulator of Main Steam system isolation valve MSIV-170. A plant operator was dispatched according to the alarm response procedure to perform a pre-charge check of the accumulator. A pre-charge check returns hydraulic fluid from the accumulator to a vented tank that serves as a fluid reservoir. During this operation the fluid reservoir tank and supporting piping were damaged by the rapid expansion of nitrogen gas that had entered the hydraulic system by way of a leak across an accumulator piston O-ring. As a result of the damage and loss of hydraulic fluid, MSIV-170 and its associated hydraulic accumulators were declared inoperable at 1307 Mountain Standard Time. It was determined at that time that the failure of the fluid reservoir due to rapid expansion did not constitute an explosion and a declaration of an Unusual Event was not made according to Emergency Action Level (EAL) HU2, 'Fire within the Protected Area not extinguished within 15 minutes of detection or explosion within the Protected Area.'
"Subsequent review has determined that the reservoir failure should have been characterized as an explosion within the Protected Area and that a declaration of an Unusual Event should have been made per EAL HU2.
"The NRC Resident Inspector has been notified."
The licensee has notified the State of Arizona and Maricopa County. |

JAMES RUBENSTONE (NMSS)
| Event Text UF6 PRESENT IN THE SMALL COMPONENT DECONTAMINATION TRAIN
"(1) Radiological or chemical hazards involved, including isotopes, quantities, and chemical and physical form of any material released Uranium-hexafluoride (UF6):
"3.1 grams of solid UF6 was present in the Small Component Decontamination Train (SCT) and was assumed to be enriched to 5 weight percent U235. Thus 0.16 grams of U235 were present. Neither criticality nor chemical release occurred.
"(2) Actual or potential health and safety consequences to the workers, the public, and the environment, including relevant chemical and radiation data for actual personnel exposures to radiation or radioactive materials or hazardous chemicals produced from licensed materials (e.g. level of radiation exposure, concentration of chemicals, and duration of exposure):
"None; the administrative limit to ensure criticality is prevented is 730 grams of U235. The mass present was about two ten-thousandths of the administrative mass limit. This administrative mass limit is less than one half of the analyzed 0.95 keff safe mass.
"(3) The sequence of occurrences leading to the event, including degradation or failure of structures, systems, equipment, components, and activities of personnel relied on to prevent potential accidents or mitigate their consequences:
"The IROFS prevent the accumulation of U235 above the administrative mass limit of 730 grams U235 in the SCT. The IROFS determine a net weight of residual material in a container by comparing the initial, prior to first use, tare weight to the empty weight, after outgassing.
"It was discovered that upon cleaning, the technicians were determining a net weight using the most recent empty weight, not the prior to first use tare weight. This resulted in the potential to nullify the weight of remaining trace quantities of residual material.
"This represents a failure of management measures such that no IROFS, as documented in the ISA summary, remain available and reliable, in an accident sequence evaluated in the ISA, to perform their function. Therefore, this one hour event report being completed in accordance with 10 CFR 70 Appendix A (a)(4).
"(4) Whether the remaining structures, systems, equipment, components, and activities of personnel relied on to prevent potential accidents or mitigate their consequences are available and reliable to perform their function:
"All structures, systems, equipment, components, or activities of personnel remain available and reliable to perform their safety functions.
"(5) External conditions affecting the event;
"There were no external conditions that affected this event.
"(6) Additional actions taken by the licensee in response to the event:
"The area was isolated, operations in the SCDT were halted and a criticality anomalous condition was declared per Operating Requirement Manual. An immediate reconciliation of the IROFS54a and 54b mass record logs was completed and it was determined that the mass present in the SCDT, 0.155 grams U235, was well below the administrative mass limit of 730 grams.
"(7) Status of the event (e.g., whether the event is on-going or was terminated);
"No event occurred; there was insufficient material present for criticality to be possible. No release of licensed material occurred. This event was the discovery of a failed management measures related to an IROFS.
"(8) Current and planned site status, including any declared emergency class;
"Plant is running at full capacity. This event did not warrant any change in plant status. No declared emergency occurred nor are any planned.
"(9) Notifications, related to the event, that were made or are planned to any local, State, or other Federal agencies;
"No notifications other than this report have been made nor are any planned.
"(10) Status of any press releases, related to the event that were made or are planned.
"No press releases have occurred nor are any planned." |
