Event Notification Report for December 17, 2003

TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO LOSS OF BOTH TRAINS OF SAFETY INJECTION

The following information was obtained from the licensee via facsimile:

"1. SYSTEMS AFFECTED: High Pressure Safety Injection (HPSI), Low Pressure Safety Injection (LPSI), Recirculation Actuation [System] (RAS), Containment Spray (CS).

"2. ACTUATIONS AND THEIR INITIATING SIGNALS: None

"3. CAUSES: 400 [volt] Motor Control Center (MCC) 3BE deenergized due to an overcurrent condition on the 'A' train 1E bus. 'B' train equipment is cleared for maintenance causing Technical Specification 3.0.3 entry.

"4. EFFECT OF EVENT ON PLANT: Both trains of Safety Injection equipment inoperable with no flow capability requiring plant shutdown.

"5. ACTIONS TAKEN OR PLANNED: Shutdown commenced at 0410 [PST]. MCC 3BE is stripped and loads will be checked for faults while attempting to restore the bus. Train 'B' equipment will be restored as soon as possible.

"Continuation Sheet: Power/Mode will be reduced per T.S. 3.0.3 action until MCC 3BE loads restored or Tr[ain] 'B' equipment returned to service. [Plant required to be in] Mode 3 [within] 7 hrs, Mode 4 [within] 13 hrs. [and] Mode 5 [within] 37 hrs. No abnormal electrical lineups. No effect on Unit 2. LPSI pump/valves will need to be restored to allow Mode 5 entry."

Plant personnel suspect a problem with the 1E bus feeder breaker. A new breaker will be installed after testing is completed. Bus loads are in the process of being checked for problems. At the time of the initial call, plant power was at 80% and decreasing at approximately 10% per hour. At 0939 PST, plant power was at 71% and decreasing. The 1E bus have been meggered with no problems found. Battery chargers are currently not operating due to loss of the buses but not expected to be a problem since DC loads are very low during mode 1 operations.

The licensee has notified the NRC Resident Inspector.

REFUELING EQUIPMENT RECEIVED AT LASALLE STATION EXCEEDING RADIATION LIMITS

"This notification is being made in pursuant to Exelon Reportability manual RAD 1.11 and 10 CFR 20.1906(d)(2). At 11:30 CST on 12/17/03, Radiation Protection Technician notified the Shift Manager that a Radiation Shipment (03-1216-02) was received at LaSalle from Duratek (Memphis, TN) that exceeded 200 mrem/hr on the external surface of the package. In accordance with 10 CFR 71.47(b)(1) the package was not in a closed transport vehicle and thus did not meet the exclusion to allow the package to be greater than 200 mrem/hr and less than 1000 mrem/hr. The as found readings on the package were measured at 211 mrem/hr and verified with a second instrument at 207 mrem/hr. The package was also surveyed for contamination and found to be free of loose contamination. Pursuant to 10 CFR 20.1906(d)(2), the final delivery carrier (R&R Trucking Co) was also notified of this event."

The gauge was contained in a yellow transport case and is a Troxler Model 3430, Serial Number 33308. The gauge contains approximately 10 millicuries of Cesium-137, and 40 millicuries of Americium-241. The theft of the gauge was reported to the Arizona Radiation Regulatory Agency at approximately 1325 MST.

The licensee issued a press release offering a $500.00 reward for the recovery of the gauge.

The Arizona Radiation Regulatory Agency and the licensee will continue to investigate this occurrence and report further.

The FBI, States of CA, NV, NM, CO, and the country of Mexico are being notified of this event.

AGREEMENT STATE - POTENTIAL LEAK ON P-32 SOURCE WIRE

The following is taken from an email received from the State of Texas, Department of Health:

"This is a Texas agreement state incident being forwarded based on a 5 day report requirement for a leaking source. (Incident 8083) The Licensee reporting the incident is Guidant located in Pearland, TX, L05178. More information is anticipated. This is a preliminary report.

"Today a returned P-32 [Phosphorus-32] source wire was received at our Pearland facility. This facility is authorized for radioactive material use under license number L05178. The source wires we manufacture are registered with the TX-BRC as TX-1070-S-101-S. These source wires are sent to our user sites [hospitals] and returned to Pearland for decay and disposal.

"The active portion of the source wire was wiped during the receipt survey. Approximately, 8.0 nCi [nanocuries] of activity was removed at that time. The source wire was stored for investigation at that time.

"A later wipe showed removable activity of approximately 0.5 nCi [nanocuries]. We will continue to investigate the source wire to determine if the wire is leaking or if the contamination was from another source."
