Event Notification Report for April 13, 2005

DURING CORE RELOAD REACTOR TRIP BREAKERS OPENED

"The plant is in Mode 6 (Refueling) and core reload is in progress with the reactor trip breakers open; both trains of solid state protection system are in the operate mode.

"While restoring a line up to place the 'D' steam generator on recirculation, a path was opened that allowed the 'B' steam generator to transfer water to the 'D' steam generator. This alignment lowered the 'B' steam generator to its low-low set point level. This initiated a reactor trip signal (RPS). With the reactor trip breakers open and the reactor core reload in progress, no components actuated as a result of the signal. If the emergency feedwater system had been in service, this would have resulted in equipment actuation. This is an 8-hour report per 10 CFR 50.72 (b)(3)(iv)(A). The resident inspector has been notified."

VALID RPS ACTUATION DUE TO AN INVALID ATWS LOGIC ACTUATION

"At 0953 [CDT] on 04/13/2005 with Unit 2 in MODE 4 [and] all Control Rods inserted, a valid RPS Actuation (Reactor SCRAM Signal resulting from the filling of the SCRAM DISCHARGE VOLUME) was received as a result of an invalid ATWS initiation. This occurred during the performance of 2-SR-3.3.5.2.4(FT) RCIC SYSTEM LOGIC FUNCTIONAL TEST. Further review of the test revealed that a Volt/Ohm Meter was attached across contacts in the ATWS LOGIC that conflicted with the RCIC Surveillance and apparently resulted in the ATWS initiation and the filling of the SCRAM DISCHARGE VOLUME.

"This event is reportable as an 8-hour Non-Emergency Notification along with a 60-day written report in accordance with 10CFR50.72 (b)(3)(iv)(A) & 10CFR50.73(a)(2)(iv)(A) as 'Any event or condition that results in valid actuation of RPS & PCIS as described in (1) & (2) below.' "

The licensee notified the NRC Resident Inspector.

AGREEMENT STATE - STOLEN TROXLER MOISTURE DENSITY GAUGE

The following information was provided via email from the State of Arizona (State text in quotes):

"At approximately 11:00 AM April 13, 2005, the Agency was informed that the Licensee had a pickup truck stolen with a Troxler Model 3401B gauge, SN 10444. The theft occurred between 7:00 PM, 4/12/2005 and 4:00 AM, 4/13/2005. The truck is a green 1995 Nissan. The Troxler gauge was locked in a 16 gauge steel box with a hardened and anti-theft designed lock and hasp. The steel box is bolted to the frame of the truck. The truck license number is Arizona [DELETED]. The gauge contains 8 mCi of Cesium-137 and 40 mCi Am:Be-241.

"Phoenix PD is investigating and has issued report number 2005-50689301.

"The Licensee is offering a $500.00 reward for the recovery of the truck and sources. A press release is to be made.

"The Agency continues to look for the source.

"The states of CA, NV, CO, UT, and NM and Mexico and U.S. NRC and FBI are being notified of this event."

"The Phoenix Police Department recovered the truck on April 18, 2005. The gauge does not appear to have been opened. The truck suffered minimal damage."

R4DO (Shannon) and NMSS (Flanders) notified. TAS notified via e-mail.

WASHINGTON AGREEMENT STATE REPORT - STOLEN MOISTURE DENSITY GAUGE

The following information was provided by the State via email:

"As reported by the licensee's RSO, the event occurred on 4/13/05, between 9:00am and 10:45am. A CPN Model MC-3, portable moisture/density gauge, serial number M36127293, was stolen from an employee's personal vehicle, parked in the lot of the licensee's office. The car was locked and the gauge was hidden from view beneath the interior hatch cover. However, the gauge was not secured within the car by use of a second, independent security method. The passenger side window was broken; the gauge and a tool box were the only items stolen. The car was apparently parked beside bushes in the parking lot, screening the passenger side of the car from view. The Police (Case Number 051030408), a CPN Representative, and our office were notified soon after the break-in was noticed.

"No on-site investigation is planned. No media attention was noted. Isotope and Activity involved: 370 MBq (10 mCi) Cs-137 & 1850 MBq (50 mCi) Am-241/Be"

RADIOACTIVE MATERIAL INADVERTANTLY PUT INTO NORMAL TRASH

On 4/15/05, the licensee discovered that two vial sources were missing. Upon investigation, it was determined that the vials were inadvertently put into the normal trash dumpster on 04/13/05. One vial contains 134 microCuries Cs-137 and the other contains 74 microCuries Ba-133 (both activities as of 04/15/05). The vials were described as approximately 2-inches in height and 1-inch in diameter. The licensee believes that the vials were not labeled.

The licensee notified the trash pickup company (Midco) and is currently waiting for a return call.

RECEIPT OF TWO UNIDENTIFIED RADIOACTIVE SOURCES WITHOUT DOCUMENTATION

Dianon Systems is a diagnostic laboratory licensed by the NRC to handle P-32 and I-125. On April 13, 2005, Dianon received a shipment of two radioactive sources without any information as to what the sources were, their strength (i.e., radioactivity), or what diagnostics where to be performed. Dianon immediately contacted the originator of the shipment, a doctor out of Brooklyn, NY. The doctor was not willing to provide any information on the sources other than to say that the sources were "6 months old, safe, and no threat." Dianon surveyed the sources and found that they were still radioactive, however, the caller was unable to provide a meaningful millirem/distance reading.

Dianon has safely secured the sources in lead shielding and is uncertain on how to proceed in resolving disposition of the sources.
