AGREEMENT STATE REPORT - SCRAP METAL SHIPMENT FOUND TO CONTAIN UNIDENTIFIED RADIOACTIVE MATERIAL
The Oregon Department of Radiation Protection Services received notification, from a scrap metal recycler in Portland, Oregon, that a shipment of scrap metal, for recycling, contains unidentified radioactive material causing low levels of radiation outside the transport vehicle. The shipment originated from a company located in Missoula, Montana. The shipment is under special permit DOT-SP-10656 without a determination of materials meeting or not meeting the regulatory definition of radioactive material. The shipment is a minor radiological concern [approximately 6,000 cpm] based on considerations of the U.S. Department of Transportation and the state official aligning this shipment approval document.
The radioactive material was detected in a truck at a scrap metal recycler's portal monitor in Portland, Oregon. The unidentified item is suspected to be located on the left side, near the landing gear, and on the floor of the trailer. The driver was directed to not rearrange the contents of the truck and the shipment will be returned to the originating company in Missoula, Mt. There is no suspected release of radioactive material, radiation exposures, or personnel injury or contamination.
The state is continuing it's investigation and has notified the Montana Department of Public Health.
Oregon State Incident Docket # 13-0457 and RPS # 13-0024.

EMERGENCY DIESEL GENERATORS UNAVAILABLE FOR AUTO-START
"At 16:15 PDT on 6/24/13, an operator performing a post-event annunciator alarm review of the event reported in EN #49143 identified that the operators the previous night had momentarily disabled all three Unit 1 emergency diesel generators, prior to restoring them to their automatic standby control alignment. Between 22:01:10 PDT and 22:02:54 PDT, on 6/23/13, less than the required minimum two diesel generators were available to automatically respond to a design basis accident. Due to the event reported in EN #49143, the start-up 230 kV power source was also unavailable at this time.
"At the time of this event the operators were in the procedurally guided process of placing the running diesel generator controls to manual, shutting down the running diesel generators, and returning them to the automatic standby control alignment. In this event the operators placed all the diesel generators in manual and shut them down before returning them to automatic control. During this time the operators would have responded to a plant event by returning the affected diesels to auto, whereupon the normal starting and loading sequence would have resumed in accordance with existing accident analyses.
"At the time of discovery all offsite and onsite power sources were operable."
The licensee notified the NRC Resident Inspector.
