The following report was received via e-mail:
"On October 10, 2017, the Department [Wisconsin Department of Health Services] received a telephone call and email from the licensee's medical physicist that a medical event occurred on August 11, 2017, involving a permanent implant of I-125 seeds for a prostate manual brachytherapy procedure where the total dose delivered differs from the prescribed dose by 20 percent or more. This is a medical event as described in DHS 157.72(1)(a)1.a. The prescribed dose was 145 Gy; the dose delivered was 90 Gy. The licensee uses D90 (dose delivered to 90 percent of the clinical target volume) < 80 percent of prescribed, for determining medical events. Using the licensee's dose based criteria; the dose received by the prostate was 62 percent of the intended dose. The underdose was identified during the post-implant computerized tomography scan on September 11, 2017 and subsequent dosimetric analysis on October 10, 2017.
"DHS [Wisconsin Department of Health Services] inspectors will investigate this medical event."

* * * UPDATE ON 4/26/18 AT 1238 EDT FROM JOSEPH ROSS TO BETHANY CECERE * * *
The following update was received from the Wisconsin Department of Health Services (DHS) by email:
"During the ongoing investigations of other medical events reported to the Wisconsin Department of Health Services in 2017, licensee reviewed historic permanent implants of I-125 seeds for prostate manual brachytherapy. The licensee recently identified two additional implants that resulted in a D90 dose to the prostate that was greater than 130 percent of the prescribed dose. The licensee noted that there were no adverse outcomes to the patients.
"The first implant occurred on August 28, 2015. The prescribed dose to 90 percent of the prostate (D90) was 145 Gy and the D90 delivered was 192 Gy.
"The second implant occurred on June 17, 2016. The prescribed dose to 90 percent of the prostate (D90) was 145 Gy and the D90 delivered was 189 Gy.
"DHS is reviewing the circumstances surrounding these two implants as part of the investigation into the previously reported medical events."

| Event Text WRITTEN DIRECTIVE FOR RA-223 ADMINISTRATION INCORRECT
A quarterly review conducted on 4/17/18, identified that the written directive for administration of Ra-223 was incorrect. The written directive stated that the Ra-223 should be administered orally, but should have stated that it was to be administered intravenously (IV). The review determined that there was no impact to any patients as a result of the error in the written directive. The review identified one case where the written directive was used. However, the technician administered the Ra-223 to the patient via IV and not orally.
The corrective actions taken by the licensee were to correct the written directive, and review the directive with the technician to understand why the technician did not consult with the physician when there was an error in the directive.
The licensee notified the NRC R3 Office (Warren).

| Event Text MISADMINISTRATION OF SIR-SPHERES Y-90 MICROSPHERES RESULTING IN AN UNDERDOSE
The following was received from the State of Washington via email:
"Patient was under treated with Y-90 SIR-Spheres Microspheres. Prescribed dose was 24.59 mCi. Patient was treated with 8.9 mCi.
"Background: SIR-Spheres Microspheres Activity Calculator determined a treatment dose of 0.91 GBq (24.59 mCi). Written Directive was signed for 0.91 GBq. Prescribed dose was entered into the Treatment Worksheet as 0.91 mCi. Dose activity delivered to the interventional radiology procedure room (Dose In-Vial) was recorded as 0.96 mCi.
"Analysis: Radioactivity units of measurement varied between Written Directive and Treatment Worksheet. Radioactivity activity readings from the dose calibrator were recorded with a systematic error. Calibrator reading multiplication factor(x10) was not applied. Therefore, the vial pre-dispense Y-90 activity reading of 8.62 mCi should have been recorded as 86.2 mCi. Dose activity delivered to the IR procedure room was in fact 9.60 mCi rather than 0.96 mCi.
"Y-90 SIR-Spheres treatment on 3/30/2018 was incomplete because the prescribed 0.91 GBq prescribed dose was not administered. Standard post-procedure verification check identified the under treatment. The patient was informed by the prescribing physician and scheduled for a second treatment on 4/6/2018. The second Y-90 SIR-Spheres treatment was performed on 4/6/2018 and the remaining dose was administered to complete administration of the prescribed 0.91 GBq."

The following report was received from the Nebraska Department of Health via email:
"Eagle Distributing of Norfolk, LLC sold their building which contained tritium exit signs to Our Savior Lutheran Church on October 17, 2017. Eagle Distributing did not inform Our Savior Lutheran Church of the General License [GL] responsibility until March of 2018 when the Annual Renewal for GL0595 came overdue. After Our Savior Lutheran Church was informed of the exit signs and their GL responsibility, Our Savior Lutheran Church conducted a search to locate the signs within the building resulting in 3 missing signs. They have no information as to what could have happened or specific dates of their removal."
NE Item Number: NE180003
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.

"River Bend Station experienced an inadvertent initiation and injection of High Pressure Core Spray (HPCS) at 1531 [CDT] on 4/26/2018 while operating at 100 percent power.
"During replacement of Level Transmitter B21-LTN081C 'Reactor Vessel Low Water Level 1', Main Control Room received an inadvertent initiation and injection of High Pressure Core Spray. The HPCS injection valve was open for approximately 40 seconds before the operators manually closed the valve.
"Feedwater Level Control responded per design and maintained Reactor Water Level nominal values. The Division 3 Diesel Generator (DG) also automatically started in response to the actuation signal. The DG did not automatically connect to the Division 3 switchgear since there was not a low voltage condition on the bus.
"The manual closure of the injection isolation valve caused the system to be incapable of responding to an automatic actuation signal. The manual override of the injection isolation valve was reset approximately 16 minutes after the event, restoring the system to its standby condition. This event is being reported in accordance with 10 CFR 50.72(b)(2)(iv)(A) as a condition that caused ECCS [Emergency Core Cooling System] discharge to RCS [Reactor Coolant System] and 10 CFR 50.72(b)(3)(v)(D) as a condition that caused the loss of function of the HPCS System.
