The following report was received via fax:
"On December 20, 2016, a leak occurred during an administration of Yttrium-90 (Y-90) TheraSpheres to a patient, resulting in less than 80% of the prescribed dosage being administered. A total of about 8.99 millicurie of Y-90 activity was administered; or 34.6% of the prescribed 25.95 mCi activity. The prescribed dose was 17,470 rad (174.7 gray), with the leak resulting in a dose to the patient's liver of about 6,040 rad (60.4 Gy). The leak also caused contamination of the administration area, which was immediately and successfully decontaminated. As an under-dose, no immediate harmful effect to the patient resulted from the event. The referring physician and patient were made aware of the event during the procedure."

| This material event contains a "Less than Cat 3 " level of radioactive material. | Event Text AGREEMENT STATE REPORT - LEAKING KRYPTON-85 SOURCE
The following report was received via e-mail:
"On November 17, 2016 the Agency [Texas Department of State Health Services] received notice from a service company that it had a gauge which appeared to have leaked the radioactive material. The gauge potentially leaked Krypton-85 gas because the device failed to operate normally. The device activity did not produce acceptable measurements and was removed from service/operation. The device was removed from service by the service company and set into a storage area and labeled to prevent movement. The licensee made arrangements for the manufacturer to service the gauge stating to the Agency [Texas Department of State Health Services] that it would take the manufacturer three weeks before it could schedule a visit to the plant site. The manufacturer must confirm that Kr-85 indeed did leak from the gauge.
"Device information provided included by the licensee:
Manufacturer - Valmet/Metso,
Gauge model - BMW2,
Gauge S/N - 50048138,
Isotope - Kr-85,
Activity - 400mCi,
Source S/N - QA00168.
"On December 23, 2016, the licensee verbally confirmed the device had leaked the Kr-85 gas. The manufacturer will be providing a service description and details of how the device was checked and or repaired. Awaiting the service report from the manufacture."
The seam on the source capsule had ruptured.
Texas incident: I-9442
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.

The following report was received via e-mail:
"On December 22, 2016, UCLA's alternate RSO for UCLA sent an e-mail to an RHB ICE inspector for the Radiologic Health Branch [RHB] to report a medical event, per 10 CFR 35.3045.
"A patient with metastatic sarcoma of the liver was treated by an authorized user at the medical center with Sirtex SIR-spheres containing yttrium-90 (Y-90) on December 22, 2016. A post treatment dose assessment was completed by radiation safety personnel. The authorized user prescribed 0.2 GBq (5.49 mCi) of Y-90 SIR-spheres to the left lobe of the patient's liver, but only 4.07 mCi or 74.1% was delivered. This underdose of 25.9 % caused a medical event to be reported. The patient was also treated with Y-90 SIR-spheres to the right lobe of the liver in compliance with the physician's written directive. The patient was notified by the physician and UCLA's radiation safety office is investigating the cause of the event."

"Oyster Creek Generating Station has experienced a loss of the TSC [Technical Support Center] ventilation system.
"If an emergency is declared requiring TSC activation during the time TSC ventilation is non-functional, the TSC will be staffed and activated using existing emergency planning procedure unless the TSC becomes uninhabitable due to ambient temperature, radiological, or other conditions. If relocation of the TSC becomes necessary, the Emergency Director will relocate the TSC staff to an alternate location in accordance with applicable site procedures.
"This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) due to a potential loss of the TSC. An update will be provided once the TSC ventilation has been restored to normal operation.

"On December 28, 2016 at 2119 EST, the Standby Liquid Control system (SLC) subsystem A was declared inoperable in accordance with the surveillance instruction for performance of a routine surveillance test. At 2229 EST, control room operators received an out-of-service alarm for the explosive-actuated injection valve for SLC subsystem B and declared subsystem B inoperable, thereby rendering both subsystems inoperable. With both subsystems inoperable, the SLC system was unable to fulfill its safety function. At 2335, the surveillance was completed and subsystem A was restored to operable status, which restored the ability for the system to fulfill its safety function.
"Troubleshooting determined that the cause for subsystem B inoperability was an intermittent electrical connection for the explosive-actuated injection valve. Repairs were conducted and the subsystem was restored to operable status on December 29, 2016 at 1708 EST.
"This issue was entered into the Corrective Action Program and during post reportability review, it was determined that this was a reportable event under 10 CFR 50.72(b)(3)(v)(A) for an event or condition that could have prevented the fulfillment of a safety function of a system that is needed to shut down the reactor and maintain it in a safe shutdown condition and under 10 CFR 50.72(b)(3)(v)(D) for a system that was unavailable for accident mitigation.

"On 12/30/16 at 1302 EST, Unit 1 began withdrawing control bank rods for an approach to criticality following a refueling outage. At 1305 EST, operators observed that control rod H-6 did not withdraw. Operators entered the applicable Abnormal Operating Procedure. Operators tripped the reactor as required by plant procedures and entered applicable Emergency Operating Procedures. The act of manually tripping the reactor generated a valid trip signal in the plant Reactor Protection System.
"Following the reactor trip, all safety related equipment operated as designed. Auxiliary feedwater was already supplying the Steam Generators; a Feedwater Isolation occurred due to plant conditions.
"Unit 1 is currently being maintained in Mode 3 at NOT/NOP, approximately 548 degrees F and 2235 psig, with auxiliary feedwater supplying the steam generators, and decay heat removal via the steam dumps.
"Method of decay heat removal is Steam Generators via the steam dumps. Current reactor coolant system conditions: Temperature at 548 degrees F and stable, pressure 2235 psig and stable. All control and shutdown banks are inserted. Electrical alignment is normal, supplied by offsite power. No impact to Unit 2, Unit 2 is in Mode 1 at 100 percent power."
