AGREEMENT STATE REPORT - MISSING SOURCE

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

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.

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."

PATIENT ADMINISTERED THE WRONG BYPRODUCT MATERIAL

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.

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.

60-DAY OPTIONAL TELEPHONIC NOTIFICATION FOR AN INVALID CONTAINMENT VENT ISOLATION ACTUATION

"This 60-day telephone notification is being submitted in accordance with paragraphs 10 CFR 50.73(a)(1) and 50.73(a)(2)(iv)(A) to report an invalid Containment Vent Isolation (CVI) actuation at Watts Bar Nuclear Plant (WBN) Unit 2.

"On April 14, 2016 at 1344 Eastern Daylight Times (EDT), Unit 2 technicians performing calibration checks on the Auxiliary Building general supply fan, connected test equipment to the wrong intake temperature switch, causing an invalid train B auxiliary building isolation (ABI) signal in both Unit 1 and Unit 2.

"Because the Unit 2 containment purge system was, at that time, configured in the 'refuel' mode, the invalid train B ABI concurrently initiated a train B CVI in WBN Unit 2. Consequently, the train B CVI caused the Unit 2 containment lower compartment radiation monitor to trip and control room operators entered Technical Specification Limiting Condition for Operation (LCO) 3.4.15 RCS Leakage Detection Instrumentation at 1344 EDT.

"By 1422 EDT, Unit 2 control room personnel had reset the containment purge system and by 1854 EDT had completed procedural steps to restore auxiliary building ventilation to its normal alignment. By 1858 EDT, Unit 2 control room personnel had completed the procedural steps to restore the containment purge system.

"During this event, the train B ABI and CVI actuations were complete and equipment functioned as designed. Upon identification of the train B ABI/CVI condition, the calibration activities were halted and a prompt investigation was initiated. WBN evaluators determined the apparent cause of the event was incorrect work instructions, with a contributing cause that technicians failed to use human performance error prevention tools to ensure they were calibrating the correct equipment. Personnel responsible for performing the calibration checks have been coached and corrective actions have been taken to correct the work instructions."

The licensee notified the NRC Resident Inspector.

PART 21 - SWITCHES NOT ENVIROMENTALLY QUALIFIED

"TopWorx Information Notice: TIN 2016-01

"13 June 2016

"Subject: C7 Switches

"Equipment Affected By This Information Notice: (4) C7-14521-E25 shipped on 6 August 2014

"Purpose: The purpose on this TopWorx Information Notice (TIN) is to alert Fisher that, as of 27 May 2016, TopWorx was made aware of a situation which may affect the performance of the aforementioned equipment. TopWorx is informing Fisher of this circumstance in accordance with Section 21.21 (b) and 50.55 (e) of 10 CFR 21.

"Applicability: This notice applies only to (4) TopWorx C7-14521-E25 shipped on 6 August 2014 to Fisher on Fisher Purchase Order 4123318082.

"Discussion: Fisher Purchase Order 4123318082 specified that TopWorx SV7-14521-E25 were to be provided. Although the C7 switches provided to Fisher in error are also Nuclear-qualified switches, they do not have the same qualification pedigree and therefore cannot be considered qualified for HELB [High Energy Line Break] applications (zones 5 and 10). TopWorx has no indication that the switches provided are defective, yet TopWorx is unable to determine the application or status of use and therefore submits this notice.

"Extent of Condition: Fisher Purchase Orders were reviewed and no other order was found where an incorrect switch was provided.

"Actions Required: If the units mentioned above are to be installed in a zone for which the C7 switch is not qualified, then the units must be replaced. In addition, TopWorx has initiated a Non Conformance Report (NCR 05192016-01) to prevent reoccurrence of this issue.

"10 CFR 21 Implications: TopWorx requests that the recipient of this notice review it and take appropriate action in accordance with 10 CFR 21.

ALERT SIRENS FAILED TO ROTATE

"At 1845 CDT on June 13, 2016, TVA Corporate Emergency Preparedness notified the Shift Manager at Browns Ferry Nuclear Plant that eight of the BFN [Browns Ferry Nuclear] Alert & Notification Sirens (19, 39, 55, 59, 60, 61, 69, 95) failed to rotate. The sirens were activated at 0915 CDT. Post sounding siren feedback indicated thirteen sirens that failed to rotate. BFN EP [Emergency Preparedness] Senior Instrument Mechanics were dispatched to inspect the thirteen sirens and determined, through field inspections that only eight sirens would not rotate. The field inspection was completed and communicated to Corporate Emergency Preparedness at 1733 CDT.

"Per NPG-SPP-03.5.1, the affected sirens which were lost affect 25.1 percent of the Emergency Planning Zone (EPZ) population and the sirens are not expected to be returned to service within 24 hours. Per NPG-SPP-03.5.1, a Loss of Alert and Notification System Capability exists when there is an unplanned or planned loss of primary Alert and Notification System (ANS) equipment for greater than one hour resulting in a loss of capability to alert 25 percent or more of the total Emergency Planning Zone (EPZ) population and either the Federal Emergency Management Agency (FEMA) approved backup alerting method cannot be implemented for the area affected by the lost primary ANS equipment OR the primary ANS equipment is not expected to be returned to service within 24 hours.

"TVA Corporate Emergency Preparedness is redirecting a team from Watts Bar Nuclear Plant to commence repairs on Wednesday 6/15/2016.

"This 8 hour notification is being made per the reporting requirements specified by 10 CFR 50.72(b)(3)xiii.

"The NRC Resident Inspector has been notified.

"This event has been entered in the Corrective Action Program."
