LOSS OF EMERGENCY SIRENS
The following information was provided by the licensee via facsimile (licensee text in quotes):
"On March 2, 2005, at approximately 1239 hours [EST], the transmitter antenna that provides the signal that activates the emergency sirens was determined to be inoperable during testing activities. This affected the system's ability to automatically activate the emergency sirens. The antenna system was restored to service at 1249 hours on March 2, 2005. All sirens re-tested satisfactorily. This event is a loss of the Emergency Notification System and is reportable under 10 CFR 50.72(b)(3)(xiii)."
The equipment was repaired by replacing faulty components. Troubleshooting the failure is in progress. Sirens were last tested satisfactorily on 02/23/05.
The licensee will notify the NRC Resident Inspector.

AUTOMATIC ACTUATION OF MOTOR DRIVEN AFW PUMPS DURING OUTAGE
The following information was provided by the licensee via facsimile (licensee text in quotes):
"At 1629 [EST] on March 2, 2005, McGuire Nuclear Station Unit 2 experienced an automatic actuation of the 2A and 2B Motor Driven Auxiliary Feedwater (MDCA) Pumps. At the time of these actuations, Unit 2 was in MODE 3 in a refueling outage, the 2A Main Feedwater (CF) Pump was in service and, as per procedure, the 2B CF Pump was in a tripped condition and out of service.
"While performing system evolutions, Unit 2 CF system pressure unexpectedly dropped to a level that caused initiation of a low CF pump suction pressure signal which tripped the 2A CF Pump. Since the 2B CF Pump had previously been placed in a tripped condition, the logic for automatic start of the 2A and 2B MDCA Pumps was satisfied and these pumps started as designed. Since the 2A and 2B MDCA Pumps started in response to actual plant conditions or parameters satisfying the requirements for initiation of the Auxiliary Feedwater (CA) System safety function, this represented a valid actuation of the CA system reportable under the requirements of 10 CFR 50.72(b)(3)(iv)(A) .
"Note that the 2A and 2B MDCA Pumps started and operated normally and Unit 2 remained in a stable condition during this event. Unit 2 CF system parameters and alignments have been returned to normal for the current plant MODE and conditions. The 2A and 2B CA Pumps are now off."
The licensee notified the NRC Resident Inspector.

RECEIPT OF RADIOACTIVE MATERIAL WITHOUT PROPER CONTROL
An 89 curie Iridium-192 Gamma Radiography Camera (Model 660) was received at a Naval warehouse in Guam without proper controls or receipt inspection. The Navy Master Materials licensee representative states that the radiography camera was sent by AEA (the camera vendor) to a submarine tender stationed in Guam without preshipment notification or any request for the camera by Naval personnel stationed on the tender. The camera was received by the warehouse on March 2, 2005, and placed in warehouse storage without procedural control related to the receipt of radioactive materials. On March 14, 2005, during unrelated survey of materials in the warehouse, the camera was discovered. The submarine tender radiographer was contacted and performed receipt inspection and survey and determined that there is not radiological problems and the camera source is in its proper safe storage position. This event is still under investigation and a 30 day written followup report will be prepared. The licensee is reporting this event under 10 CFR 20.2201(a)(1) because the material was not under proper control from March 2 through March 14, 2005.
The licensee has notified the NRC regional inspector (Masnyk-Bailey) and NRC HQ (Bhachu).
