PRESSURIZER HEATER SLEEVE LEAKAGE

The following information was obtained from the licensee via facsimile (licensee text in quotes):

"ANO (Arkansas Nuclear One) Unit 2 shutdown on 3/9/05 at approximately 0038 [CST] to begin the 2R17 refueling outage. While performing the Mode 3 Hot Shutdown Walkdown on ANO Unit 2, evidence of leakage was discovered around three (3) pressurizer heater sleeves. The amount of leakage was minor since no indication of moisture was present and the build up of boric acid was minimal. Investigations are underway as to the repair of the affected nozzles."

The licensee notified the NRC Resident Inspector.

OFFSITE NOTIFICATION DUE TO INVESTIGATION OF INADVERTENT SIREN ACTIVATION

The following information was obtained from the licensee via facsimile (licensee text in quotes):

"On Tuesday 3/8, a local radio station carried a message about inadvertent siren soundings on the previous weekend. Neither the Arkansas Department of Health (ADH) staff nor ANO EP staff received any notifications relative to the inadvertent sounding or the number or location of the sirens. The ADH considers the sirens to be operable. A possible cause was reported as loss of electric service in some areas. ANO has some history that indicates power surges may cause inadvertent actuation of the sirens."

The licensee has notified the NRC Resident Inspector.

PLANNED LOSS OF THE EMERGENCY RESPONSE DATA SYSTEM

The following information was obtained from the licensee via e-mail (licensee text in quotes):

"On Thursday, March 10, 2005 San Onofre Nuclear Generating Station, Unit 2, will remove a portion of the Safety Parameter Display System (SPDS) and the Emergency Response Data System (ERDS) from service for a planned upgrade to ensure long-term reliability and improve the human-machine interface. This work is expected to complete within seven days.

"The SPDS emergency assessment function at San Onofre is implemented by a combination of the Qualified Safety Parameter Display System (QSPDS) and the Critical Function Monitoring System (CFMS). The QSPDS portion, which provides emergency assessment capability to plant operators in the control room, will remain functional. The CFMS portion, which receives input from the QSPDS, implements the ERDS and communicates data to the Technical Support Center and Emergency Offsite Facility. Only the CFMS and ERDS are impacted by this upgrade.

"This planned CFMS outage is being reported in accordance with 10CFR50.72(b)(3)(xiii) as a courtesy notification even though only a portion of the SPDS will be removed from service and preplanned compensatory measures will be in place for the duration of the work.

"At the time of this report, Unit 2 and Unit 3 were operating at about 79 percent and 99 percent power, respectively.

"The NRC Resident Inspectors will be notified of this occurrence and will be provided with a copy of this report."

Should an emergency event occur, the licensee intends to transmit emergency response data to the NRC via facsimile and voice via the emergency notification system. No electronic data will be sent to the NRC Operations Center for the outage duration.
