| Event Text AGREEMENT STATE REPORT - INDIVIDUAL OVEREXPOSURE OF PHARMACY TECHNICIAN
The following report was received from the Florida Department of Health Bureau of Radiation Control via email:
"[The Florida Department of Health Bureau of Radiation Control] received an email reporting an overexposure at Triad Isotopes Inc. On Jun 5, 2017, Triad's Corporate Safety Officer received exposure notifications (both whole body and ring dosimeters) from Landauer involving the same individual."
The first notification was for the period 4/1/2017 - 4/30/2017; doses were: whole body Deep Dose Equivalent (DDE) =2545 mrem, Lens Dose Equivalent (LDE) =2545 mrem, Shallow Dose Equivalent (SDE) =2452 mrem.
The second notification was for the period 5/15 - 5/21; doses were: left ring dosimeter 11000 mrem, right ring dosimeter 4670 mrem.
"On Jun. 5, 2017 Triad overnighted the whole body badge for the period of 5/1/2017 5/31/2017 to be read . Landauer notified Triad of the exposure notification on Jun. 9, 2017, whole body doses were: DDE=10953, LDE=14971 mrem, SDE=17913 mrem. Probable causes and corrective actions are outlined in the report from Triad. ERCM [Environmental Radiation Control Materials] will conduct the follow-up."
Technician A was immediately prohibited from entering the restricted area or handling radioactive materials. The isotopes involved are believed to be Mo-99/Tc-99m, Tc-99m, and Ga-68. An investigation was performed and identified the root causes as multiple procedural adherence issues, a human behavior error, and possible exposure to badges while not being worn. Retraining of all employees has been conducted and other steps are on-going.

"At 1400 [EDT], St. Lucie completed a review of Unit 1 Hot Leg Injection scenarios. St. Lucie Unit 1 was licensed with a Hot Leg Injection capability that relies upon manual actions to accomplish the function. This review concluded that some postulated single electrical train failure scenarios were not fully addressed in plant procedures. Because of the potential to extend Hot Leg Injection initiation beyond the analysis start time, St. Lucie is reporting this condition under 10 CFR 50.72(b)(3)(ii)(B).
"The affected off-normal procedures were immediately revised to include necessary instructions to restore power to selected valves during a postulated loss of electrical power to restore the Hot Leg Injection strategy. Unit 1 remained at 100% power.
"The NRC Resident Inspector has been notified."
A review found this condition was not applicable for Unit 2. | |
