AUTOMATIC REACTOR TRIP DUE TO HIGH REACTOR COOLANT SYSTEM PRESSURE
"Crystal River Unit 3 was at 37 percent power starting up from a refueling outage. During troubleshooting of control problems with the B Main Feedwater Pump, a feedwater transient occurred which underfed the steam generators. This resulted in a reactor trip on high Reactor Coolant System pressure and Emergency Feedwater Actuation on low steam generator levels. This event is reportable as a 4-Hour Non-Emergency Notification per 10CFR50.72 (b)(2)(iv)(B) for Reactor Protection System Actuation and as an 8-Hour Non Emergency Notification per 10CFR50.72 (b)(3)(iv)(A) for Emergency Feedwater Actuation."
The licensee reported that all control rods fully inserted on the trip and that steam generator safety valves lifted and reseated as expected. The primary system is currently at 2155 psi, 549 degrees F with steam generator feedwater being supplied by auxiliary feedwater. The main condenser is available and is being used for primary system heat removal via steam dump. The station electrical grid is stable and in normal configuration; the emergency diesel generators are operable and in standby.
The licensee has notified the NRC Resident Inspector.

LOST OR STOLEN MOISTURE/DENSITY GAUGE
At approximately 1700 MST on 11/5/03, a technician using a CPN model MC-3 moisture density gauge was told to relocate her vehicle on the jobsite at 8247 Shaffer Place in Littleton, CO. The gauge contains 10 millicuries of Cs-137 and 50 millicuries of Am-241, with serial number M380804502. The technician placed the gauge inside its orange transport box in the back of her truck, but she left the tailgate open, and did not chain the box to the bed of the truck.
The technician left the jobsite at approximately 1730 MST to return to the main office 25 miles away. Shortly before arriving at the main office, the technician realized that the truck bed was open and the transport box (and gauge) were not in the truck. The technician turned around and re-traced her route back to the jobsite, but was unable locate the gauge. The technician reported the missing gauge to the Radiation Safety Officer (RSO) at 1830 MST. The RSO, along with other supervisors, retraced the route to the jobsite and searched for the gauge, which was not found.
The licensee notified the Colorado Department of Public Health and Environment (CDPHE) at 0530 MST on 11/6/03. The CDPHE informed the licensee that a written report is required within 30 days. The licensee notified local law enforcement officials regarding the lost gauge, and issued a press release offering a reward for information leading to its recovery.
