| Event Text SOURCE TRAIN DID NOT RETRACT
"After IVB therapy the source train did not retract due to a kink in the IVB catheter, did not retract to the remote Beta-Cath device. The IVB catheter was immediately withdrawn and placed in the Novoste emergency plexiglass storage safe and then in the IVB storage room. No overexposure was received by the patient or attending staff. Novoste has been notified of the malfunction. The Novoste Beta Cath was returned to the manufacture on August 2, 2004. The IVB manufacturer is Novoste Beth Cath, source Sr-90, 1.71 GBq (46 millicuries). Transfer device Serial No. 92917, and Source train Serial No. ZA543. The device was packaged and returned to the manufacturer on August 2, 2004. This agency did not receive notice of the event within 24-hours"

| Event Text US ARMY RADIOACTIVE MATERIAL INVOLVED IN A FIRE.
On August 13, 2004 and aircraft hanger located on Fort Wainwright, East of Fairbanks, burned to the ground. Three chemical detectors containing a total activity of 70 millicuries of Nickel-63 were stored inside a metal wall locker within the aircraft hanger. The aircraft hanger has been cordoned off and a US. Army Radiation Safety Officer (RSO) is on the scene. One ICAM, and Two M22 Acada chemical detectors were stored in the metal wall locker. |

At 12:15 PM on 8/20/04, it was discovered that actions performed on 7/16/04 in support of Dry Fuel Storage activities to defeat the Railroad Access Area Radiation Monitor alarm horn had also defeated the actuation capability of the Railroad Access Process Radiation monitors. Per Technical Specifications, the process monitors are required to be operable "during movement of irradiated fuel assemblies within the Railroad Access Shaft, and above the Railroad Access Shaft with the Railroad Access Shaft Equipment Hatch open." Contrary to the Tech Spec requirement, two loaded Dry Fuel Storage Casks were lowered in the Railroad Shaft, one on 8/2/04 and the second on 8/16/04, with the radiation monitors inoperable. During this period the automatic isolation and re-alignment of Reactor Building Zone lll, automatic start of Reactor Building Recirculation Fans, and the automatic starts of SGTS and CREOASS would not have actuated from a HI-HI Radiation condition in the Railroad Access Shaft. Actual radiological conditions observed during the transfer of the casks in the railroad shaft would not have resulted in the need for system actuation. All other instruments in the Reactor Building ventilation system which actuate these systems were operable as required by Tech Specs. The jumpers which defeated the actuation capability were removed on 8/20/04 at 1400 [hrs.].
This event is considered reportable under 50.72(b)(3)(v)(C) as a loss of safety function.
The NRC Resident Inspector was notified. |

The following information was provided by the licensee via facsimile:
"[The] High Pressure Coolant Injection (HPCI) flow controller malfunctioned resulting in the inability of the HPCI to perform its safety function as a single train system under 10 CFR 50.72 (b)(3)(v). The failure mode for the flow controller is suspected to be a power supply issue, however, the cause has not been confirmed at this time. Unit 2 is in a 14 day technical specification [T.S.] limitation which if exceed results in a unit shutdown ( T.S. 3.5.1 Condition C)."

"At 1010 CDT on 8-22-2004, during the performance of STS IC-211B, 'ACTUATION LOGIC TEST TRAIN B SOLID STATE PROTECTION SYSTEM,' Control Room operators received a reactor trip concurrent with power range flux lo [low] setpoint trip and intermediate range hi [high] flux reactor trip alarms.
"All safety-related equipment operated as required. The Steam Dump valves, which function to remove excess heat as the secondary systems shutdown, did not initially operate as expected, resulting in the operation of the Steam Generator Atmospheric Relief Valves (ARVs) to control Reactor Coolant pressure for approximately three minutes following the reactor trip, at which time the Steam Dump valves responded as expected and the ARVs closed. The Steam Dumps are currently operating correctly in automatic.
"The Auxiliary Feedwater System actuated as designed.
"The plant is currently stable in Mode 3 at Normal Operating Temperature and Pressure while plant personnel investigate the causes of the reactor trip and formulate the repair/ restart plan.
"A press release is planned."
During the reactor trip, all control rods fully inserted. The electric plant is in a stable shutdown plant lineup. Plant personnel also intend to investigate the unusual response of the steam dump valves.
