"A medical event occurred on 8/18/2017 when Y-90 TheraSpheres meant for treatment of the patient's left liver lobe were administered to the patient's right liver lobe. The patient treatment plan was for radioembolization of the left lobe of the liver on 8/18/17 and radioembolization of the right liver lobe approximately one month later. The interventional radiologist (IR) and radiation oncologist authorized user (AU) signed off on planning activity for the left lobe via the left hepatic artery on 8/2/17 and 8/3/17, respectively. The AU completed the 8/18/17 written directive to deliver 124 Gy to the left lobe via the left hepatic artery (LHA). The IR placed the catheter for treatment in the right hepatic artery which supplies the right liver lobe. The AU, medical physicist and radiation technologist came to the procedure room. A time out procedure was done asking all parties to confirm 124 Gy to the left lobe via the LHA. The IR gave a verbal affirmation of this plan. The IR discovered the error when reviewing patient notes following the procedure. He immediately notified the AU who then notified the Radiation Safety Officer (RSO). The AU estimated dose to the right lobe to be 63 Gy. The RSO continues investigating the event. The patient and the referring physician were notified of the medical event."

| Event Text PART 21 REPORT - ONCENTRA BRACHY SOFTWARE ERROR
The following is excerpted from a report received from the Georgia Department of Natural Resources:
On August 8th, a patient was undergoing a gynecological treatment using a ring applicator with the microSelectron HDR utilizing Oncentra Brachy Software version 4.5.2. On the 2nd of a 4 fraction treatment of ring and tandem, a mistreatment occurred due to inconsistent step size when treating the ring source path. A source step size of 2.5 mm was planned. What was reported in the case explorer was a 5 mm step size. This plan was sent to the TCS [Treatment Control System] and delivered at a 5 mm steps size.
It was intended to treat specific areas, but the delivered areas were 2.5 mm - 60 mm different than intended.
This was confirmed using gafchromic film on a QA plan after treatment was completed.
This event was reported by the State of Mississippi - see related EN 52914.
Elekta identified that this issue occurs when using Applicator Models with a measured source path in combination with a specific afterloader configuration, as follows:
Oncentra Brachy - Version 4.5, 4.5.1, 4.5.2, Applicator Modeling with a measured source path, RDStore default step size 5.0 mm, 10.0 mm
Afterloader - microSelectron HDR/PDR V2, V3/Digital
Applicators - Ring Applicator Sets, Ring CT/MR Applicator sets, Interstitial CT/MR Rings, Vienna CT/MR Rings, Advanced Gynecological Applicator - Venezia with Lunar-shaped ovoids
In Elekta bulletin [IFSN 806-01-BTP-001] the Ring applicator will be used to represent all applicable applicators. Where ring is mentioned also lunar-shaped ovoids apply (Advanced Gynecological Applicator). Where 5.0 mm is used as a default step size this could also be 10.0 mm.
Oncentra Brachy incorrectly handles the placement of the ring applicator models with the measured source path in combination with the microSelectron treatment unit, for which the default step size differs from 2.5 mm.
Three other facilities previously reported this issue and the manufacturer had started working on a bug fix and field notification. All other cases found the issue during QA, so no patients were involved. Veenendaal has put a stop to the delivery of the Applicator Modeling until the Oncentra Brachy v 4.5.3 is released.
An Important Field Safety Notification was sent to all customers concerning the use of ring source paths with applicator modeling on 8/11/17 (IFSN 806-01-BTP-001 attached).
An Oncentra Brachy patch is in process to fix this safety issue. |

"Pursuant to 10 CFR 21, this is a non-emergency notification by Nebraska Public Power District (NPPD) concerning a defect in an Allen-Bradley 700DC-P220Z2 relay received at Cooper Nuclear Station.
"On August 28, 2017, NPPD completed a 10 CFR 21 evaluation of a condition that was identified on April 25, 2016, associated with an Allen-Bradley 700DC-P220Z2 relay delivered by NuTherm. The evaluation was performed to determine the applications where the relays were approved for installation, where they were installed in the plant, and determine if the failure of the relays could result in a Substantial Safety Hazard as defined in 10 CFR 21.
"A model 700DC-P220Z2 relay failed after 133 hours of service. An independent laboratory determined the relay contained a wound wire fault at the beginning of the spool near the spool edge. The wire that faulted was connected to the right coil terminal. The fault was at a stress point where the wire came out of the insulating material channel and started onto the spool. Continuity testing indicated that the wire was open between the fault area and the terminal, within the potting material. The relay failure was a case of component infant mortality. It appeared the fault was caused by a manufacturing flaw that likely occurred due to a tensioning issue at the start of the coil wire winding process.
"This deviation presents a Substantial Safety Hazard as defined in 10 CFR 21, as this relay model was approved for use in safety related applications. The relay that failed was installed in the starter for the HPCI auxiliary lube oil pump and caused the HPCI system to be inoperable. This was reported to the NRC in ENS Notification 51882 at 0154 EDT on April 26, 2016 as a loss of safety function, but was not characterized as a 10 CFR Part 21 issue at that time. The relay model was approved for use in numerous HPCI starters and the Recirculation Pump discharge valves."
The licensee notified the NRC Resident Inspector. |

The following information was received via e-mail:
"Fisher Information Notice: FIN 2017-04: Erroneous Rotary Seating Torque Calculation in FlowScanner Software
"This Fisher Information Notice (FIN) applies only to the equipment identified in Appendix A, which lists serial numbers and order numbers that were delivered to customers. Specifically, it applies to FlowScanner 6.6 (build 6.6.000.29) and 6.6 SP1 (build 6.6.000.67). Appendix B of this document includes a decision tree to help customers further determine if this FIN applies to any work performed.
"The purpose of this FIN is to alert affected customers that, as of 29 June 2017, Fisher Controls International LLC (Fisher) became aware of a situation which may affect the performance of the aforementioned equipment. Fisher is informing affected customers of this circumstance in accordance with Section 21.21 (b) of 10 CFR 21.
"In the process of updating a customer's older FlowScanner software version to 6.6.000.67 (SP1), the customer performed additional software acceptance validation and discovered a discrepancy between the two software versions when calculating Seating Torque values for Rotary Valve assemblies with Lever Arm linkage type. An equation in 6.6.000.67 is the cause for the discrepancy. This equation was incorrectly written in code with a lack of an additional set of parentheses to order the execution of mathematical functions correctly. In code writing, this is considered a typographical error.
"When FlowScanner 6.6 was in development, there was a need to incorporate a new actuator design into the FlowScanner torque calculations. Because of the design of this actuator, the torque equations and configuration database in FlowScanner required modification. This code was modified on 7 November 2012. FlowScanner 6.6 (build 6.6.000.29) and 6.6 SP1 (build 6.6.000.67) were released subsequent this date and contained the erroneous calculation. Shipments of software were stopped on 30 July 2017 and no shipments took place between 29 June 2017 and 30 July 2017. This code was not transferred to the QUIKLOOK FS software utilized on the QUIKLOOK 3-FS diagnostic system. Thus, this error does not extend into QUIKLOOK FS software.
"The equation has been corrected and full-installation CDs will be ready for distribution to affected customers by 1 December 2017. In addition, a Corrective Action Request (CAR 2017-009) has been initiated by Fisher to prevent reoccurrence of this issue. Additionally, Software Error Notice SEN17-01 was created and released to affected customers on 2 August 2017.
"Fisher requests that the recipient of this FlN review it and take appropriate action in accordance with 10 CFR 21. If there are any technical questions or concerns, please contact:
