AGREEMENT STATE REPORT - RA-226 SOURCE FOUND IN GARBAGE TRUCK
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.

REACTOR PRESSURE BOUNDAY LEAKAGE
"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 10CFR50.73.
"At approximately 2335 [MST] on April 10, 2016, while performing planned routine visual examinations of Unit 1 components in the Containment Building, engineering personnel identified white residue on the piping instrument nozzle for the reactor coolant system (RCS) 2B cold leg resistance temperature detector, 1JRCET121Y. The white residue was dry and no active leakage was noted on the instrument nozzle.
"Preliminary chemical analysis for radionuclide and boron content of the white residue determined the existence of boron and the isotopic content was consistent with RCS fluid. At 0535 [MST] on April 11, 2016, it was determined the residue resulted from RCS pressure boundary leakage, based on results of the chemical analysis and additional examination of the piping and instrument nozzle by qualified engineering personnel. Technical Specifications Limiting Condition of Operation (LCO) 3.4.14 permits no RCS pressure boundary leakage and therefore, the discovery of leakage from the instrument nozzle represents a degradation of a principal safety barrier. This notification is being made for a degraded condition pursuant to the requirements of 10CFR 50.72(b)(3)(ii)(A).
"The unit has been shut down for its 19th refueling outage since 4/9/16 at 0000.
"The NRC resident inspectors have been informed of this condition."
