NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - FAILURE OF RADIOGRAPHY SOURCE TO RETRACT
The following information was received via E-mail:
"On June 1, 2018, the Agency [Texas Department of State Health Services] was notified by the licensee that a radiography crew was unable to retract a 50 Curie Iridium-192 source into an INC 100 exposure device. The crew was working in a remote area in West Texas when they could not get the source to go past the inlet nipple of the exposure device. After a few attempts, the crew contacted the licensee and an individual authorized to recover sources was sent to the site.
"The licensee did not have specific information on how the source was retracted, but stated it took the individual about 45 minutes to recover the source. The source was returned to the fully shielded position. The exposure device and source were returned to the licensee's storage area and will be sent to the manufacturer for inspection. The licensee stated the exposure device was surveyed and radiation levels were normal.
"The licensee reported that one individual's 0 - 200 millirem self-reading dosimeter did go off scale. The individual's OSL dosimeter has been sent to the licensee's dosimetry processor for reading. The licensee stated it calculated the individual's dose to be 400 millirem based on an interview with the individual. The licensee stated no individual involved received an exposure that exceeded any limit. No member of the general public received an exposure from this event. Additional information will be provided as it is received in accordance with SA-300."
Texas Incident #: I-9578
* * * UPDATE FROM ART TUCKER TO GEROND GEORGE ON 7/11/2018 AT 1125 EDT * * *
The following information was received from the State of Texas via email:
"On June 1, 2018, the licensee reported one of its crews were unable to retract a 50 curie iridium - 192 source to the fully shielded position. The licensee's written report received June 29, 2018, stated one of the radiographers had disconnected the guide tube from the exposure device and saw the source was not in the shielded position. The licensee stated the radiographer would have been in contact with the guide tube for 3-5 seconds. The individuals badge was sent for processing and had a reading of 312 millirem DDE. The licensee's initial calculation for the exposure to the individuals hands was 450 millirem. The Agency questioned the dose assessment to the hand. On July 11, 2018, the licensee's radiation safety officer stated they have contacted a service company to perform the dose calculations for the individuals hands. Pictures of the individuals hands taken on July 11, 2018, show no adverse effects from the exposure."

PART 70 APP A (b)(1) - UNANALYZED CONDITION | Person (Organization):
MIKE ERNSTES (R2DO)
NMSS_EVENTS_NOTIFICATION (EMAIL)
FUELS GROUP (EMAIL) | Event Text UNANALYZED CONDITION RESULTING FROM INCORRECT IMPLEMENTATION OF ITEMS RELIED ON FOR SAFETY (IROFS)
"Appendix A to 10 CFR 70 (b)(1)
"An incorrect implementation of IROFS36c (Limit Cylinder Mover to Electric or Diesel with less than 280L [74 gallons] Fuel Load) has been identified as having occurred for feed deliveries into the Cylinder Receipt and Dispatch Building (CRDB). IROFS36c requires that UF6 transporters/movers inside CRDB truck bays utilize a tractor which has a limited fuel capacity of less than 74 gallons. This requires the Over the Road (OTR) tractor truck to disconnect the trailer in a designated staging area and a local tractor with a fuel tank capacity less than 74 gallons be utilized with the OTR trailers. Methods were used allowing an OTR truck trailer to access the CRDB with the OTR tractor and fuel tanks of the vehicle remaining outside. Activities involving OTR tractor trailers entering the CRDB truck bay in this manner have not been evaluated in the ISA.
"10 CFR 70.50 (c)(iii)
"(A) There was not a material release, no radiological or chemical hazards were present.
"(B) No exposure occurred
"(C) A condition exists which resulted in the facility being in a state that was different from that analyzed in the Integrated Safety Analysis. The method for cylinder transport into the CRDB truck bay by an OTR tractor, in proximity to cylinders inside the CRDB, has not been specifically evaluated as the evaluated condition prohibited the use of vehicles with fuel capacities in excess of 74 gallons within the CRDB truck bay. The only piece of equipment which entered the CRDB was the OTR trailer; the tractor remained connected and outside the CRDB.
"(D) IROFS36c remains available and reliable to perform its safety function. The identified deficiency only affects OTR tractors that could potentially expose UF6 cylinders in the CRDB to fuel sources greater than 74 gallons. UUSA [Urenco USA] has issued a stop work to prevent the introduction of excessive fuel capable of causing a release of UF6 inventory in the area of concern should a fire occur. The capabilities of existing IROFS are sufficient to meet the performance requirements of 10 CFR 70.61.
"(iv) No external conditions affect this event.
"(v) A stop work was issued to prevent the access of OTR tractor trucks to the CRDB where proximity to UF6 cylinders could occur.
"(vi) An event did not occur at UUSA. UUSA remains in a safe and stable condition.
"(vii) Current and planned site status is normal. No emergencies have been or will be declared.
"(viii) No local, state, or federal agencies will be notified.
"(ix) No press releases will occur.
"Condition has been entered into the UUSA Corrective Action Program. Event Record 125051."
The licensee will notify R2 (Lopez).
* * * RETRACTION ON 07/11/2018 AT 1534 EST FROM BLAKE BIXENMAN TO STEVEN VITTO * * *
"EN53445, made June 5th, 2018, reported a condition in accordance with Appendix A to 10 CFR 70 (b)(1) in which the facility was in a state different from that analyzed in the Integrated Safety Analysis, and which resulted in failure to meet the performance requirements of 10 CFR 70.61.
"This report was prompted by an incorrect implementation of IROFS36c (Limit Cylinder Mover to Electric or Diesel with <280L Fuel Load) during feed deliveries into the Cylinder Receipt and Dispatch Building (CRDB). An Over the Road (OTR) tractor containing greater than the maximum allowable fuel load was permitted access the CRDB Truck Bay with the OTR truck trailer.
"At the time of the report, this method for cylinder transport into the CRDB Truck Bay by an Over the Road (OTR) tractor in proximity to cylinders inside the CRDB had not been evaluated. URENCO USA conservatively assumed a failure in the performance requirements of 10 CFR 70.61 at the time of the 24 hour report. Since the time of the initial report, URENCO USA has completed an assessment of safety significance for the events reported in EN53445.
"With detailed results documented in the UUSA corrective action program, Event Record EV125051, the following conclusion has been made:
"The fuel delivery events using the OTR truck into the CRDB can be categorized as events with low safety significance since they would not result in breached/ruptures of UF6 cylinders and no uranic material would be released in the event of a fire involving UF6 cylinders in the CRDB Truck Bay. This correlates with a low consequence event.
"Based on calculations shown in the 'Assessment of Safety Significance for Events Documented in EV125051', the conditions reported in EN53445 did not result in failure to meet the performance requirements of 10 CFR 70.61. Therefore, the condition reported in EN53445 did not exceed the criteria which would necessitate an event be reported to the NRC. URENCO USA hereby retracts Event Notification 53445."

NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - UNPLANNED CONTAMINATION
The following information was received from the State of Kansas via email:
"The licensee had an incident with an I-131 patient that resulted in the Iodine Patient room being badly contaminated along with the patient's bed and some other room furniture. The room is secured and removed from service. When the licensee has their Weekday management staff meeting on Monday, they develop a plan to complete the room decontamination and return it to service. The room is removed from clinical service at 2100 today (15 Jan 16).
"The contamination is contained within the room and there is no risk to Hospital staff or members of the public. No unintended dose to the patient, staff or other personnel. The patient was on a Foley catheter with the urine bag in a roll able pig. She got out of bed and walked around the room and "dragged" the pig. The hose connection inside the pig was damaged and urine spilled inside the pig and some was spilled on the floor. No one was contaminated - skin or clothing ... just the floor. The easily removable contamination / urine is cleaned up and will leave the room to decay for a half-life. That will make clean-up easier and also will reduce dose to those who are involved in the detailed cleanup.
"The licensee will notify the department when the room is returned to service.
"6/28/2018 - Patient administered 159.8 milliCuries Iodine-131 on 1/13/2016.
"The patient placed on a catheter because they were incontinent, had early Alzheimer's, and was not able to comply with instruction.
"The patient catheter with urine bag was placed in a 'rollable pig' which was dragged around the room when the patient walked around the room. The hose connection was damaged about the second day and urine spilled in the pig and onto the floor covering, bedding, linens, and absorbent chucks.
"The patient was released with an estimated 28 milliCuries Iodine-131 remaining on 1/15/2016.
"The initial room survey indicated high contamination levels. The decision was made to allow the contamination to decay over the weekend to allow for lower exposure to personnel performing the decontamination, and determine the contamination levels, location and a plan to decontaminate the room.
"The contamination was determined to be confined to the bed (mattress), linens, absorbent chucks and plastic sheeting. Minor contamination was found on the floor under the plastic sheeting.
"The contaminated items were removed from the room and held for 10 half-lives decay.
"The floor was surveyed and contaminated spots were decontaminated. The room was returned to clinical service Monday morning 1/18/2016. The time out of service was approximately 60 hours.
"6/29/2018 - Integrated Material Performance Evaluation Program (IMPEP) review identified the event had not been reported to the NRC as required."

NMSS_EVENTS_NOTIFICATION (EMAIL) | Event Text AGREEMENT STATE REPORT - STUCK SHUTTERS
The following was received from the Commonwealth of Kentucky via fax:
"On 6/28/18 while conducting a 6-month physical inventory and shutter check (on-off mechanism) the licensee, ARKEMA, Inc., discovered the shutters malfunctioned on two separate fixed gauging devices, namely:
"1) TN Technologies fixed gauging device model 5208 Serial No. MB 4251 containing 8 Ci Cs-137. The licensee has attempted to contact Thermo Scientific to repair the shutter. The root cause of the failure of the on/off mechanism was due to corrosion and dust due to the gauging device's environment. This licensee produces industrial chemicals and the gauging device is operated in a corrosive environment. This event was reported to the [Kentucky Radiation Health Branch] KY RHB as required by regulation on 6/29/18.
"2) Ronan Engineering fixed gauging device model SA-1 Serial Number M8107, containing 5 Ci Cs-137. The licensee has contacted Ronan Engineering and repairs will be conducted during the week starting on 7/16/18. This licensee produces industrial chemicals and the gauging device is operated in a corrosive environment. The event was reported to KY RHB as required by regulation on 6/29/18.
"No accidental overexposures have been reported due to the malfunction."
