AGREEMENT STATE REPORT INVOLVING MOISTURE DENSITY GAUGE VEHICLE ACCIDENT

"At approximately 2:15 PM [MST] October 9, 2003 the Agency was informed by the Licensee that a truck carrying a moisture-density gauge had been involved in a single vehicle accident and the driver is dead. The reporting individual indicated that they were informed of the accident by the Department of Public Safety. The accident occurred on AZ Highway 260 between Bridgeport and Camp Verde. The moisture-density gauge is a Troxler Model 3440, SN 27494. The device contained 40 mCi Be:Am-241 and 8 mCi Cs-137 [mCi=millicuries]. The device remained in the transporting box inside a locked steel box in bed of pick up. The Licensee is trying to retrieve [it] from law enforcement for storage and leak test. [It is] Currently in an impound yard in Mayer, AZ.

"Agency continues to receive information regarding this fatality. The Agency is unaware of any press coverage regarding radioactive materials.

"The U.S. NRC is being notified of this event."

AZ First Notice: 03-19

*****UPDATE ON 10/17/03 AT 13:30 FROM GODWIN TO LAURA*****

"The leak test was negative. It appears the driver was not wearing his seat belt."

STEAM AND FEEDWATER RUPTURE CONTROL SYSTEM UNANALYZED CONDITION AT DAVIS BESSE

"System Affected : Steam and Feedwater Rupture Control System (SFRCS)

"Actuation / Initiator Affected: Main Steam Line Rupture on Steam Generator

"Effect of event on plant in current Mode - None

"Actions Taken or planned: Declared SFRCS Actuation Channels 1 and 2 inoperable. Will track as a Mode 3 restraint against T.S. 3.3.2.2 (SFRCS Instrumentation). Will resolve, correct and retest prior to entry into Mode 3.

"Discovered SFRCS Logic Channel 1 block upon restoration and repowering after maintenance activities on 10/16/03. After discussions with Engineering Department representatives it has been determined that a design issue exists with the SFRCS system where it would be possible that SFRCS Channels 1 and 2 low pressure trips could be blocked during a scenario where a Main Steam Line Rupture would be followed by a loss of off-site power. This would result in the potential that the OTSG [once through steam generators] with the main steam line rupture would be fed by the AFW system. This requires an 8 hour notification to the NRC per 10CFR50.72(b)(3)(ii)(B)."

The licensee notified the NRC resident inspector.

LOSS OF EMERGENCY ASSESSMENT CAPABILITY

The Wolf Creek Nuclear Plant Information System (NPIS) became unavailable for unknown reasons. Loss of the NPIS affects the Safety Parameter Display System (SPDS). The SPDS forms a significant portion of the Wolf Creek emergency assessment capability. There is no other loss of emergency assessment capability concurrent with this continuing loss of the SPDS. Plant personnel have entered applicable procedures and are taking local readings of equipment normally monitored by the NPIS.

The licensee has notified the NRC Resident Inspector.

* * * * UPDATE FROM DAVE DEES TO MIKE RIPLEY 0842 ET 10/19/03 * * * *

"The SPDS was restored to service at 0621 CDT 10/19/03."
