| Event Text AGREEMENT STATE REPORT - POTENTIAL MEDICAL UNDERDOSE
The following information was received via e-mail:
"ODH [Ohio Department of Health] was notified of a potential medical event by Fairview Hospital. The licensee performed a permanent prostate seed implant using I-125 according to the treatment plan. When the post implant dosimetry was performed, the D90 coverage was calculated to be 73% of the prescribed dose. After an initial investigation by the licensee, it was determined the under dose was caused by an 18% increase in prostate size compared to the pre-plan, which was prescribed 6 weeks prior to treatment.
"At the time of reporting, the licensee had informed the referring physician but they did not inform the patient. The licensee believes that once the inflammation subsides the D90 coverage will be within the prescribe treatment plan.
"NMED will be updated once ODH receives additional information from the licensee and conducts an investigation of the event."

| Event Text AGREEMENT STATE REPORT - RADIOGRAPHY CAMERA MALFUNCTION
The following report was received via e-mail:
"A crew with [Shawcor] experienced a malfunction on the evening of November 21, 2017, with the INC IR-100 exposure device they were using when performing radiographic operations at Ward Petroleum (10404 E. 146th, Thornton, CO).
"Exposure Device: INC IR-100 (s/n 6839)
"Source: INC (s/n T0799) 65 curies
"After completing a radiographic exposure, the crew attempted to crank the source back into the exposure device; however, they were still able to crank the source out even after the button on the exposure device popped up to indicate the source was fully retracted and locked in place. After an attempt to crank the source out and back into the exposure device, the button was still popping up prematurely. Realizing there was a problem with the locking mechanism, the crew ensured their 2 mR/hr boundary was properly established and immediately contacted the Site RSO/Branch Manager. The crew maintained visual surveillance of the area until [the RSO], along with [the Assistant Site RSO], arrived at the jobsite.
"When [the RSO and Assistant Site RSO] arrived at the jobsite, they also ensured the 2 mR/hr boundary was properly established and began to assess the situation. There was no visible damage to any associated equipment (guide tube, crank assembly, etc.). They attempted several times to crank the source out and back into the fully shielded position; each time the button popped up prematurely even though the source was not locked into the exposure device. While holding down the button on the exposure device, [the RSO] was able to crank the source back in and upon releasing the button, the source locked in place. Surveys were completed to ensure the source was fully shielded.
"At no time during the incident did any crew member's dosimeter go off-scale and there was no threat of overexposure at any time to our company's employees, nor un-monitored workers. All personnel involved were wearing and utilizing proper radiation detection equipment, including OSL [Optically Stimulated Luminescent] badges, pocket dosimeters, alarming rate meters, and they were properly utilizing survey meters.
"The INC exposure device will be sent back to the manufacturer for maintenance and repair, if necessary." |

| Event Text AGREEMENT STATE REPORT - MEDICAL UNDERDOSE
Eye plaque brachytherapy was being performed using I-125 seeds with a prescribed dose of 85 Gray. After the dose, the Iso-dose curve was noted to be different from the brachytherapy plan i.e. the dose was deeper than expected. Investigation revealed that a new model plaque was used which differed from the previous model. This resulted in an underdose with 65 Gray actually administered.

"On November 30, 2017 at 1026 EST, the Susquehanna Control Room received indication that a loss of Secondary Containment Zone 2 differential pressure had occurred. Control Room operators noted a differential pressure of 0.0 inch WC [water column] for several seconds, followed by a high DP of 0.5 inch WC. System DP was restored to normal in 3 minutes. The cause of the pressure swings is under investigation.
"Zone 2 differential pressures being less than 0.25 inch WC constitutes a loss of Secondary Containment based on not meeting requirements of SR 3.6.4.1.1.
"This event is being reported under 10 CFR 50.72(b)(3)(v)(c) and per the guidance of NUREG 1022, Rev. 3, Section 3.2.7 as a loss of a Safety Function. There is no redundant Susquehanna Secondary Containment system."
The licensee notified the NRC Resident Inspector. |
