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 - TROXLER GAUGE DAMAGED BY HEAVY EQUIPMENT AT CONSTRUCTION SITE

An in-use Troxler gauge was damaged at a construction site on US 83 near Garden City, KS. The gauge, a Troxler model 3430, S/N 28271, contains a 0.3 GBq [8 mCi] Cs-137 source and a 1.48 GBq [40 mCi] Am-241/Be source. The Cs-137 source rod was extended at the time of the incident and could not be withdrawn into the shielded volume. Rad surveys on-site confirmed that both sources were intact [No contamination at the jobsite]. The gauge was returned to its case and temporary shielding used to prevent personnel exposure during transport back to the licensee's Ellsworth Office. The licensee will return the gauge to the manufacturer for disposition.

AUTOMATIC ACTUATION OF AUXILIARY FEEDWATER SYSTEM DURING SURVEILLANCE TESTING

"At 2155 hours EDT on 04/03/2017, with the unit in Mode 3 at 0 [percent] power, an automatic actuation of the Auxiliary Feedwater (AFW) System occurred during surveillance testing. The cause of the AFW system auto-start was an improperly performed procedure step to bypass the auto-start logic of the AFW pumps during performance of the surveillance test. The 'A' and 'B' AFW pumps automatically started as designed when the feedwater isolation signal was received.

"Due to the valid actuation of the AFW system, this event requires an 8-hour non-emergency notification under 10 CFR 50.72(b)(3)(iv)(A)(B)(6). At no time did this occurrence pose undue risk to the health and safety of the public.

"The NRC Resident Inspector has been notified."

EXCLUSIVE USE TRANSPORT VEHICLE EXCEEDED CONTACT DOSE RATES

"This is being reported under 10CFR20.1906(d)(1,2). At 1045 hours [EDT], the SSES [Susquehanna Steam Electric Station] Radwaste shipper was notified by the RP [Radiation Protection] shipping technician performing a receipt survey of an open transport vehicle shipped exclusive use carrying an empty radwaste liner exceeded the 10CFR71.47(b)(1) vehicle contact dose rates of 200 mR/hr. Per NDAP-QA-0720 [Nuclear Department Administrative Procedure] Attachment E, contaminated /radioactive shipments this is a 1 hour notification for exceeding the radiological receipt survey requirements of 200 mR/hr at any point on the outer surface of the vehicle."

The vehicle was from Energy Solutions. The licensee will be using the vehicle to transport radwaste from the facility.

The licensee has notified the Pennsylvania Emergency Management Agency and the NRC Resident Inspector.
