"The following event description is based on information currently available. If through subsequent reviews of this event additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS or under the reporting requirements of 10 CFR 50.73.
"At 0500 MST on May 5, 2016, engineering personnel determined that leakage from the bonnet seal weld of the Train B High Pressure Safety Injection (HPSI) system loop 2A injection valve, SIBUV0616, constituted reactor coolant system pressure boundary leakage. This is being reported as a degradation of a principal safety barrier pursuant to 10 CFR 50.72(b)(3)(ii)(A).
"The leak was identified during a planned activity in which Operations was filling the refueling pool using HPSI pump B. Leakage was stopped when a plant operator closed SIBUV0616.
"PVNGS Unit 1 was shut down for its 19th refueling outage (1R19) on April 9, 2016, at 0000 MST and is in Mode 6.
"The NRC Resident Inspectors have been informed of this condition."
* * * RETRACTION PROVIDED BY JORGE RODRIGUEZ TO JEFF ROTTON AT 1732 EDT ON 06/29/2016 * * *
"Subsequent engineering evaluation of the leak condition concluded the leakage from the bonnet seal weld of SIBUV0616 was not reportable reactor coolant system pressure boundary leakage. This conclusion was based on further reviews of the PVNGS licensing bases, ASME Code requirements, and design features of the valve with vendor assistance, which determined that the body-to-bonnet threads provide the structural support for the mechanical joint and the seal weld is not required for structural integrity of the component.
"Based on the above information, PVNGS has determined the leakage did not represent a degraded condition of a principal safety barrier as defined by 10 CFR 50.72(b)(3)(ii)(A) and Event Notification No. 51910 is hereby withdrawn.
"The NRC Resident Inspectors have been informed."

The following was received from California via email:
"The RSO of Nova Engineering and Environmental notified RHB [Radiologic Health Branch] in Brea that a Troxler yellow transport case containing a Troxler model 3411B # 18840 moisture density gauge containing 8 mCi of Cs-137 and 40 mCi of Am-241/Be was stolen from a technician's pickup truck today. The technician stated that he had loaded and secured the Type A case into his pick-up truck from a storage facility in Irvine, CA then stopped at a coffee shop before traveling to his work location. He went to unlock the gauge case and found that it had been stolen. He returned to the coffee shop, but was unable to find his gauge. He is contacting the Irvine Police Dept. to make a theft report. The RSO indicated that they lock and chain each side of the case to the truck independently and once again around the top of the case to prevent it from opening. Nova E&E does have contact information on the gauge and the case and they use a small padlock on the Cs-137 source rod handle to prevent accidental deployment."

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.

The following was received from the State of Colorado via email:
"Event Report ID No.: CO16-I16-08
"Detail: The facility hired a contractor to remodel space within the hospital. During the construction pedestrian traffic was routed around the area. According to the facility environmental health safety office the Tritium exit signs were only in use during the project.
"Event Description: It is unknown due to the extensive passage of time and the departure of employees who were involved with the project. No further information is available related to the use or the disposition of the 6 Tritium exit signs, Model # SLXTUIGW10, Serial # 162229 to 162234, H-3, 7.3 CI."
THIS MATERIAL EVENT CONTAINS A "CATEGORY 3" LEVEL OF RADIOACTIVE MATERIAL
Category 3 sources, if not safely managed or securely protected, could cause permanent injury to a person who handled them, or were otherwise in contact with them, for some hours. It could possibly - although it is unlikely - be fatal to be close to this amount of unshielded radioactive material for a period of days to weeks. These sources are typically used in practices such as fixed industrial gauges involving high activity sources (for example: level gauges, dredger gauges, conveyor gauges and spinning pipe gauges) and well logging.

The following was received from Wisconsin via email:
"On Friday, June 17, 2016, a licensee discovered contamination on a package that was used to ship I-125 prostate brachytherapy seeds. The post procedure survey of the packaging revealed elevated levels of radiation. After wipes were taken, the licensee determined that there was I-125 contamination on the inside of the packaging. There was no other contamination in the operating room. The licensee had the patient return to the facility to perform a urine bioassay. The bioassay revealed elevated levels of I-125 in the patient's urine. However further analysis will be required to determine activity concentrations. The licensee has also administered Lugols solution to the patient to block the thyroid. The department and the licensee are still collecting data to determine if this is a medical event. Site visits and updates will be performed as needed."

"This 60-day telephone notification is being made in lieu of a Licensee Event Report (LER) submittal in accordance with 10 CFR 50.73(a)(1) to notify the NRC of an invalid actuation of PCIVs, reportable under 10 CFR 50.73(a)(2)(iv)(A).
"On May 9, 2016, at 0626 Eastern Daylight Time (EDT), an unexpected trip of the Unit 1 Reactor Protection System (RPS) Bus A occurred, resulting in closure of several PCIVs on loss of power, per design. In addition, the following actuations also occurred per design:
- insertion of a half reactor scram signal.
- initiation of the standby gas treatment (SBGT) system .
- isolation of the secondary containment.
- initiation of the control room emergency ventilation (CREV) system smoke and radiation mode.
- trip of the operating reactor water cleanup system (RWCU) pump due to closure of its isolation valve.
"The event resulted from a failed relay coil in the drive motor run logic for the RPS power supply motor-generator (MG) set. The failed relay blew a fuse, which de-energized the RPS drive motor contactor and MG set. This resulted in de-energizing the RPS power supply in the 'A' channel and produced the actuations listed previously, per design. Affected systems and components were restored to their normal configurations by 1000 EDT on May 9, 2016.
"Since no plant or process conditions existed that required the PCIV isolations (e.g., high drywell pressure or low reactor water level), this event is being reported per 10 CFR 50.73(a)(1) as an invalid actuation. This issue has been entered into the site Corrective Action Program (CR 2027653) for evaluation and implementation of further corrective actions.
This event did not result in any adverse impact to the health and safety of the public.
