AGREEMENT STATE REPORT - RADIOGRAPHY SOURCE FAILED TO RETRACT

The following information was received from the State of Texas via email:

"On June 2, 2017, the Agency [Texas Department of State Health Services] was notified by the licensee that one of its radiography crews was unable to retract a 92.5 curie iridium - 192 source into a QSA 880D exposure device. The radiographers had performed several exposures. To perform the radiography, one end of a flexible guide tube was connected to the exposure device and the other end was connected to a stiff guide tube. After completing an exposure, the source hung up in the stiff guide tube and would not retract into the exposure device. The radiographers contacted their management who responded to the site. The stiff guide tube was examined and was found to have several indentations in it that appeared to be preventing the source from passing through the tube. The recovery team straightened out the guide tubes and was able to retract the source into the fully shielded position. The licensee stated the guide tube was not damaged on this date. The licensee has removed the stiff guide tube from service. Additional information will be provided as it is received in accordance with SA 300."

AGREEMENT STATE REPORT - ELEVATED RADIATION LEVELS AT A RADIOPHARMACY

The following information was obtained from the State of Illinois via email:

"On May 10, 2017, PETNET Solutions, Inc., a radiopharmacy with a cyclotron, reported high area dosimetry readings inside their facility with the highest reading being 12,276 mrem for the month of April. Readings were also elevated for the first 10 days of May. There were no neutron readings present which indicates that the readings were likely not from the cyclotron itself but from the radiopharmaceutical production process. PETNET was advised to cease cyclotron operations until their team of engineers and health physicists could determine a cause. Agency Inspectors arrived the next day, May 11, 2017, along with engineers and health physicists from PETNET to conduct an investigation at the property. Interviews with PETNET staff and an inspection of the cyclotron/hot cell did not identify any immediate problems. It was determined during the investigation that non-radiation workers opposite the adjoining wall potentially received a radiation dose during this event. The non-radiation worker involved was informed of the event, and PETNET requested permission to place TLDs and do surveys along their common wall over the next week to assess the situation. This was agreed to. In the interim the licensee estimated that the dose to the workstation in this adjoining office was 154.7 mrem. This exceeds the dose limit in regulation 32 IAC 340.310(a)(3) (10 CFR 20.1301(a)(1) equivalent). However, this dose would not represent any health effects to the individual and would be equivalent to approximately two pelvic X-rays at a doctor's office. Currently, PETNET engineers believe the root cause was related to problems in the targetry and delivery systems resulting in multiple instances of F-18 escaping from a v-vial vent. This material then accumulated in the ventilation ducts leading to the filter banks near the area dosimeters on the wall. PETNET has committed to a corrective action plan including additional maintenance on the unit, an alarming radiation detector in the cyclotron vault connected to the operator's panel and additional area dosimeters on the opposite side of the adjoining wall. IEMA [Illinois Emergency Management Agency] has committed to routine site visits until further notice."

AGREEMENT STATE REPORT - PORTABLE GAUGE OPERATOR HANDLED UNSHIELDED SOURCE

The following report was received from the State of Washington via email:

"An operator of a portable moisture/density gauge touched and directly handled the unshielded source.

"Here is how the event occurred: A worker knelt down next to a portable moisture/density gauge and pulled it up, tilted it back, and stuck his face toward the source rod. He then extended the source rod out of the gauge housing and into the air. He then took his left hand and rubbed the source rod clean with his bare hand.

"This event was observed by a manager from Oregon Radiation Protection Services, who then reported the event to the Washington State Department of Health for investigation.

"Incident Number: WA-17-014"

The portable moisture/density gauge is a Troxler 3430 containing 0.333 GBq (9 mCi) of Cs-137 and 1.628 GBq (44 mCi) of Am-241/Be.

OFFSITE NOTIFICATION FOR DISCHARGE OF CIRCULATING WATER

"On Sunday, June 11, 2017 at 1200 CDT, a Chemistry Technician reported water from the Circulating Water Blowdown (CW B/D) valve building had been pumped onto the ground outside the CW B/D building during a maintenance activity. The sump in the CW B/D building has a sump pump discharge hose that had been routed outside to the ground near the outfall canal rather than to the permitted outfall path. Water sample analysis results confirmed the presence of tritium. The sump pump discharge hose was rerouted to the required outfall on June 11th, 2017 at 1500 CDT. The discharge flow did not leave the site boundary before reaching the permitted discharge pathway.

"In accordance with the Braidwood Station Illinois Environmental Protection Agency (IEPA) Consent Order dated March 11, 2010, the IEPA was notified of the blowdown line release on June 12, 2017 at 0914 CDT; the Illinois Emergency Management Agency (IEMA) was subsequently notified. Local agencies in the Braidwood area will also be notified.

"Follow-up analyses are being performed to determine if additional IEPA or IEMA notifications will be required. The release tank values for other radionuclides (i.e., other than tritium) were interpolated based on tritium values for the release tank, dilution from the CW B/D, and sampled sump tritium values; and determined to be less than Minimum Detectable Activity (MDA).

"Within 4 hours of determination that state and local agencies notification will be made, the NRC Operations Center is required to be notified. There were no public health risks associated with the event. The NRC Resident Inspector was notified. Due to the notification of government agencies, this event is being reported under 10 CFR 50.72(b)(2)(xi)."
