The following information is a summary of the information received from the State of California:
On April 11, 2016, a City of Los Angeles garbage route truck alarmed the radiation monitors at the Athens Waste Services Sunland transfer station. The transfer station supervisor notified the California Department of Health - Radiologic Health Branch. The State dispatched an inspector to the facility. Upon arrival, the inspector was notified that the truck had returned to the City of Los Angeles East Valley Complex. The inspector travelled to the East Valley Complex.
Upon arrival at the East Valley Complex, where the truck had been isolated, the inspector was able determine the approximate location of the device in the rear of the truck. The inspector was informed that a crew was not available to dump the contents to search for the item at that time. Arrangements were made for the inspector to return when a crew was available. The truck remained isolated.
On April 14th, the inspector returned to the East Valley Complex to search for the source. A crew was assembled and the contents of the truck were dumped. Using a survey meter, the inspector was able to locate a 2.61 mCi Ra-226 radiation oncology treatment needle. No other sources or radioactive devices were discovered.
The inspector secured the source in a lead pig and placed it into the State's inventory. Prior to the removal of the source, the highest radiation reading outside the truck was 1.2 mR/hr. on contact.

The following information was obtained from the State of Washington via email:
"[The Washington Department of Health - Office of Radiation Protection] investigation continues on the Kay Ray Sensall fixed gauge shutter failure. The licensee identified, during a routine shutdown, that the handle moves on the fixed gauge but fails to open and close the shutter. The licensee reported they believe the problem is a drift pin that allows the handle to turn the shaft of the shutter to its open/close position. The shutter is in the open position and is unable to be closed. The gauge is operating normally and correctly otherwise [and is] correctly mounted."
The gauge is a Kay Ray Sensall model number 7063S with serial number S94J2306.

"On April 25, 2016, at 0607 hours [CDT], HPCI [High Pressure Coolant Injection] was isolated via the HPCI MO 2-2301-4 (HPCI Inboard Main Steam Isolation Valve) to stop a packing leak on the HPCI MO 2-2301-5 (HPCI Outboard Main Steam Isolation Valve). The packing leak was causing a steam plume potentially impacting the motor operator on the 2-2301-5 valve. HPCI was declared inoperable and T.S. 3.5.1 Condition G was entered.
"Since HPCI is a single train safety system, this notification is being made in accordance with 10CFR50.72 (b)(3)(v)(D), as an event or condition that could have prevented the fulfillment of a safety function.

"8-hour report due to HPCI inoperability.
"At approximately 2109 [CDT] on 04/25/16, a licensed operator performing a control room panel walkdown noted the green light for HPCI Auxiliary Oil Pump (AOP) was not illuminated. The bulb was replaced and the replacement bulb did not illuminate. A non-licensed operator was dispatched to the local 250VDC starter rack. Both the green and red power indicating lights on the starter rack were found extinguished. An attempt was made to start the AOP with the control switch. The pump did not start. The AOP is required to start in order to open the steam admission valves for the HPCI turbine.
"HPCI was declared inoperable at time 2117 [CDT], resulting in entry into Tech Spec LCO 3.5.1 Condition C - HPCI System Inoperable. Required Actions for Condition C are to verify by administrative means RCIC System is operable within 1 hour and restore HPCI System to operable status within 14 days. RCIC was verified operable by administrative means concurrent with HPCl declaration.
"Troubleshooting activities for HPCI are being planned.
"HPCI is a single train system. This report is submitted as a condition that at time of discovery could prevent the fulfillment of the safety function of an SSC [Structures, Systems, and Components] needed to mitigate the consequences of an accident."
The licensee informed the NRC Resident Inspector. | |
