OFFSITE NOTIFICATION
"The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via the ENS.
"At 1345 CST as part of post maintenance testing of the Comanche Peak Alert and Notification (siren) System, a polling of the system was initiated from the onsite microwave building. In response to this polling, only 5 of the system's 72 sirens initially responded. Troubleshooting determined that the 450 MHz radio system repeater used by both the siren system and the site emergency response teams was malfunctioning. Malfunction of this radio repeater made functionality of the systems intermittent and full function of neither was assured.
"The siren system and emergency response radio system have been returned to service by switching to the backup radio repeater at 1522 CST.
"There are no events in progress that required siren operation or dispatch of the site's emergency response teams.
"The NRC Resident Inspector has been notified of the siren and emergency response radio system failures."

MANUAL REACTOR TRIP DUE TO LOSS OF CONDENSER VACUUM
"Point Beach Unit 1 was manually tripped at 0339 CST on 12/13/05 due to a loss of condenser vacuum caused by a mechanical failure of the running circulating water pump. All plant systems responded normally, including an auxiliary feedwater actuation."
The trip was uncomplicated. All rods fully inserted. MSIVs were isolated due to the loss of condenser vacuum so decay heat is being removed by the atmospheric dump valves. The licensee indicated that there are no known steam generator tube leak issues. All systems functioned as required. The licensee was not in any significant LCO at the time of the trip. The trip had no impact on the electrical lineup or on Unit 2 operations. The cause of the circ water pump failure is still under investigation but there is evidence of sheared bolts on the pump coupling.
The licensee noted the turbine condenser rupture disks blew due to high pressure.
The licensee notified the NRC Resident Inspector.

MEDICAL EVENT
On 12/09/05 a patient was to receive 220 millicuries of I-131 (three capsules). The three capsules were transported in two small pigs. On Tuesday,12/13/05, one of the capsules was discovered in one of the two pigs indicating the patient only received two of the capsules. The patient will be notified.
The licensee notified Tara Weidner at NRC Region 1.
