The following information was received via E-mail:
"On May 10, 2016, the Agency [Texas Depart of State Health Services] received notification from the licensee's radiation safety officer (RSO) that the shutter on a Thermo Fisher Scientific Model 5176-SN B2578 density gauge, containing a 500 millicurie cesium-137 source SN MA3200, was found open during inventory/operational checks. It appears the weld had failed on the gauge. Open is the normal operating position of the gauge shutter. The gauge does not create an exposure hazard to the licensee's employees or a member of the general public. The licensee has contacted the service company who will inspect the gauge. Additional information will be provided as it is received in accordance with SA-300."

The following was received from the State of California via email:
"The RSO [Radiation Safety Officer] of Loma Linda Medical Center notified the RHB [Radiologic Health Branch] Brea ICE [Inspection, Compliance and Enforcement] office that they believe a medical event occurred on Friday, May 28, 2016.
"A patient was admitted to the hospital for treatment of carcinoma. The treatment plan involved [10 CFR] 35.400 use of Cs-137 sealed sources for brachytherapy with a tandem and ovoid applicator. The patient's written directive called for 3,460 cGy to target area A (left side tandem), but only approximately 1,500 cGy was delivered. The lower rectum and vaginal areas received more than expected dose, but is believed to be within tolerance. Critical organs of bladder and mid-rectum also received less than expected incidental exposure.
"The cause of the under dose was human error. The applicator tube used to place the source into the tandem had become crimped by the lead pig during transport to the patients room. During application by the resident physician and medical physicist, the resistance felt during the application process lead them to believe the source was fully deployed to the end of the tube.
"The chief physicist notified the RSO on Tuesday, May 31, 2016 at 1630 pm, of his dose calculations, in which the hospital began medical event notifications."

The following information was received by the State of Ohio via email:
"On 4/21/2016 in OR [Operating Room] 11, during seed loading, the dosimetrist noticed that one seed was missing from the transferring stylet as he was transferring the seeds to the loading needle. He immediately notified the physicist in the room. The physicist then checked the sterile area around the cartridge with a survey meter and picked up radiation reading by the luer - lock hub of the cartridge. The physicist assumed that the source had fallen in the sterile towel under the cartridge and determined loading should continue, and they will retrieve the dislodged seed after all needles have been loaded. After all needles were loaded and while implantation was still in progress the physicist and the dosimetrist went to retrieve the dislodged seed but they were not able to locate it. They resurveyed the spot where it was and there was no radiation detected. The physicist emptied the cartridge to verify the number of seeds remaining in the cartridge and the count was as stated in the loading summary. The dislodged seed was missing.
"To prevent a recurrence, surgical drapes will be used to cover the area under and around the cartridge/loading area instead of sterile hand towels. This would make it easier to identify any seed that may have fallen out during loading. Loose/broken seed(s) will be placed in the lead pig immediately. If there is a dislodged/loose seed that could not be recovered immediately, the physicist will ensure that everyone leaving the room is surveyed.
"Licensee has previously observed that I-125 seeds are prone to static buildup and have the tendency to cling to plastic, glass walls, and other surfaces. Most likely, the lost seed was swept up and discarded with normal trash.
"Based on the relatively low activity and low energy of the I-125 seed and measured background readings in the operating room, there was no radiation exposure to personnel or members of the public due to this loss."

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - MISSING SOURCE
The following information was received by the State of Ohio via email:
"On 4/26/2016, Physics reported that during prepping a return shipment the dosimetrist discovered one I-125 prostate seed was missing from the lead pig. The lead pig contained loose/broken seeds from the implant performed on 4/6/2016. There were three seeds in the vial where there should've been four. The RSO interviewed the dosimetrist and the physicist who worked this case. Inventory log and loading summary were audited. Inventory log recorded 28 seeds returned to storage. Of the 28 seeds returned, 24 were in the cartridge and 4 were loose/broken seeds stored in the lead pig. It was not until 4/26/2016 when Physics discovered only 3 seeds were in the lead pig. Radiation surveys records were audited. Surveys were performed accordingly and readings were background level.
"At this time, the seed has not been located. Based on the information provided by the medical physicist and the dosimetrist, it is still unclear as to precisely determine when and how the seed became missing. Licensee believes there was no radiation exposure to the individual(s) involved. To prevent a recurrence, two individuals shall visually count the seeds in the lead pig before leaving the operating room. Furthermore, two individuals shall review loading summary to confirm all seeds are accounted for.
"Licensee has previously observed that 1-125 seeds are prone to static buildup and have the tendency to cling to plastic, glass walls, and other surfaces. Most likely, the lost seed was swept up and discarded with normal trash. Based on the relatively low activity and low energy of the 1-125 seed and measured background readings in the operating room, there was no radiation exposure to workers or members of the public due to this loss."

The following was received via email:
"This is a report and notification of a medical event for Perry County Memorial Hospital, located in Perryville, Missouri, which occurred today June 3, 2016 at approximately 7:30 a.m. CST. This medical event is being reported as required under 10 CFR Part 35.3045 (a)(2)(i), administration of a wrong radioactive drug containing byproduct material resulting in an effective dose equivalent of greater than 0.05 Sv or 5 rem.
"At approximately 8:15 a.m. today, [The Diagnostic Radiological Physicist] received a call from Perry County Memorial Hospital, that one of his nuclear medicine technologists had inadvertently administered a 63 y/o female patient a bulk unit dose of approximately 128 mCi of Tc-99m Sodium Pertechnetate intravenously. This female patient was scheduled to receive a 25 mCi dose of Tc-99m Medronate intravenously for bone scintigraphy. Using a Tc-99m Sodium Pertechnetate package insert provided by the unit dose supplier, [the Diagnostic Radiological Physicist] estimated that the resultant effective dose equivalent to the patient will be approximately 0.06 Sv or 6 rem. The resultant highest dose to any organ or tissue is estimated to be approximately 27 rads, which would be to the patient's upper lower intestinal wall.
"The patient has been notified with regards to this medical event. In addition, the RSO [Radiation Safety Officer] / Authorized User for Perry County Memorial Hospital has also been notified."
A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient. |

| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 3 | M/R | Y | 100 | Power Operation | 0 | Hot Standby | Event Text TECHNICAL SPECIFICATION REQUIRED SHUTDOWN AND REACTOR TRIP
At 2013 EDT on 6/12/16, Millstone Unit 3 commenced a Technical Specification (TS) required shutdown due to excessive Reactor Coolant System leakage from the "A" Reactor Coolant Pump (RCP) third stage seal. The leakage from the third stage seal was approximately two gpm which is greater than the Technical Specification (TS) limit of less than one gpm.
During the shutdown, oscillations developed in the Main Feedwater which required the operator to initiate a manual reactor trip. Unit 3 is currently stable in Mode 3. Decay heat is being released via the Steam Dumps to the Main Condenser. Normal offsite power is available and the unit is in a normal shutdown electrical line-up. The cause of the Main Feedwater oscillations is being investigated.
The licensee notified the NRC Resident Inspector. The licensee notified State and local government agencies.
* * * UPDATE FROM WALTER ORF TO DONALD NORWOOD AT 0129 EDT ON 6/13/2016 * * *
The following clarifies Feedwater isolation vs. Feedwater oscillation:
"At 2337 EDT on 6/12/16, a manual reactor trip was initiated on Unit 3 following feedwater isolation. As expected, Aux Feedwater system (AFW) initiated on the reactor trip. The trip was uncomplicated and the plant is currently in Mode 3 with a normal electric line-up and decay heat is being removed via steam dumps to the condenser. This is reportable under 10 CFR 50.72(b)(2)(iv)(B) - RPS Actuation - Critical and 10 CFR 50.72(b)(3)(iv)(A) - Valid Specific System Actuation."
"The Feedwater isolation occurred due to high Steam Generator water level."
The licensee notified the NRC Resident Inspector.
