| Event Text AGREEMENT STATE REPORT - DAMAGE TO AM-241 SPECTROSCOPY SOURCE
The State of California Radiologic Health Branch forwarded the following report via e-mail:
"(1) A description of the event, including the probable cause and the manufacturer and model number (if applicable) of any equipment that failed or malfunctioned;
"A small alpha spectroscopy style source was damaged by a researcher who placed adhesive tape on the active source area. The source appears similar to an Isotope Products A-2 type.
"Removal of the tape lifted the active material and transferred it to the tape.
"Records of the source manufacturer were not available.
"(2) The exact location of the event;
"Room 369 GLAST Laboratory, Natural Sciences II Building, UC Santa Cruz campus.
"(3) The isotopes, quantities, and chemical and physical form of the licensed material involved;
"Am-241 solid, ~1 micro curie total, plated metal
"(4) Dale and time of the event;
"Occurrence on 11-13-2012 about 1:00 pm
"(5) Corrective actions taken or planned and the results of any evaluation or assessment;
"a. Suspend individual involved and laboratory supervisor until re-qualified by radiation safety on proper techniques for source handling. (Completed)
"b. Laboratory supervisor to retrain all users in specific laboratory on proper source handling. (Scheduled to be completed by 3-15-2013)
"c. Update online training materials to include information about fragility of certain types of sources. (Scheduled for 2-1-2013)
"d. Include information on the event in the next radiation safety newsletter. (Scheduled for 3-1-2013)
"e. Remove obviously damaged source from service. (Completed)
"f. Re-inspect similar sources and remove any damaged or suspect sources from service. (Scheduled for 2-15-2013)
"(6) The extent of exposure of individuals to radiation or to radioactive materials without identification of individuals by name.
"No exposure or contamination was identified in surveys conducted the day of the event." |

"On January 15, 2013 at 2112 EST while performing testing associated with the remote shutdown system at the James A. FitzPatrick Nuclear Power Plant, an unexpected loss of the 10600 bus 'B' division AC vital power system occurred. This loss of power to the 10600 bus resulted in an automatic actuation of the 'B' and 'D' Emergency Diesel Generators. The diesel generators started as expected, but did not close in to energize the 10600 Bus due to the configuration at the time of the event. As a result of the loss of the 10600 bus, the 'B' Reactor Protection System (RPS) lost power resulting in a half scram signal and a Group II Primary Containment Isolation System (PCIS) actuation. This actuation resulted in closing containment isolation valves in multiple systems and isolating Reactor Water Clean-Up (RWCU). Based on these system actuations, the event is reportable under criterion 10 CFR 50.72(b)(3)(iv).
"Power to the 10600 Bus was restored January 16, 2013 at 0400 EST, and the half scram and isolation signals have been reset. Additional actions to restore systems to a normal operating line-up are on-going. Investigation into the cause of the unexpected power loss is on-going and will be addressed through the corrective action program.
