"Site experienced a momentary loss of the NOAA Weather Radio System from 1916 to 1918 EST. During the time that this system was out of service, a major loss of offsite communication capability is considered. Site emergency planning personnel were notified and will investigate this momentary loss. The system is in service and functioning properly."
The licensee notified both state/local agencies and will inform the NRC Resident Inspector.

"After further investigation, a determination has been made that there was no major loss of offsite notification capability of the Hatch Prompt Notification System (NOAA Weather Radio System). The momentary losses reported were caused by testing of the primary audio feed line utilizing a tone generator while investigating the loss of this feed. The secondary audio feed from Jacksonville NWS remained operable during the time of testing."

While passing a SPEC 150 Industrial Radiography Camera from a boat to an Apache Corporation Petroleum platform in the Gulf of Mexico, the radiography camera fell into the water. The water depth is 60 to 70 feet and is located approximately 50 to 70 miles from the coast of LA. The lost camera was a SPEC 150 S/N 223 with a 24 Curie Ir-192 source S/N 12433B. The radiography camera was in a Type B shipping container. The licensee plans on using divers to retrieve the radiography camera. |

"On April 8, 2004, at about 2215, Cook Unit 2 experienced a feedwater flow transient resulting in oscillating flows to Nr. 22, 23, & 24 steam generators. At 2216, the high level turbine trip setpoint was reached in Nr. 24 steam generator resulting in [a] main turbine trip signal. The main turbine trip signal caused a turbine trip resulting in an RPS [Reactor Protection System] actuation (reactor trip). At the time of the RPS actuation, Cook Unit 2 was at about 50 percent power and lowering power to facilitate turbine control maintenance. The cause of [the] feedwater transient is unknown and under investigation at this time.
"Following the RPS actuation, the Auxiliary Feedwater System automatically started on low-low Steam Generator levels. This constituted a valid unplanned actuation of the Engineered Safeguards Feature (ESF). Operators stabilized the Plant using Condenser Steam Dumps and Auxiliary Feedwater. Unit 2 is currently in Mode 3 with Reactor Coolant System conditions stable at normal operating temperature and pressure. No other ESF systems actuated.
"During the response to the RPS actuation by the operating crew, it was noted that the Main generator output breaker remained closed requiring a manual trip signal to open the output breakers. Another condition identified was a leak from a crack in the side of the 'C' South condenser near the condensate booster pumps' recirculation line inlet. The operating crew removed the condensate booster pumps from service to stop condenser hotwell outleakage; the main condenser remains in service. The causes for the above items are unknown and [are] under investigation at this time."
All control rods fully inserted into the core in response to the automatic reactor trip and heat sink is currently been maintained using Auxiliary Feedwater Pumps and the Main Steam Dumps. Except as noted, all other systems functioned as required.

"On 419/04 at 1230 hours, Energy Northwest contacted Washington State Emergency Management Division (1-800-258-5990) to report a spill of pHreeGuard-4500 (a water treatment scale inhibitor) at the Columbia Generating Station Circulating Water Pump House. Washington State Emergency Management Division assigned Incident No. 04-0721 to this report. It is estimated as much as 60 gallons of the water treatment chemical could have been released to the concrete tank pedestal, asphalt apron, and adjoining soil over a period of several hours from a leaking expansion joint at the tank outlet. The leak was detected at about 0830 hrs. The leaking material is captured and redirected to the Circulating water basin. Washington State Emergency Management Division is relaying the information to the on-call responder in the Washington State Department of Ecology's Central Region Office.
" This event is being reported under 10 CFR 50.72 (b)(2)(xi), any event or situation, related to the health and safety of the public or on-site personnel, or protection if the environment, for which a news release is planned or notification to other government agencies has been or will be made."

At 1630 on 4/9/04, it was discovered the Emergency Operating Facility had lost power. It is still without power. The cause was the backup facility diesel generator started and attempted to power the facility while normal offsite power was still applied. The electrical transfer switch was damaged. The time to repair is unknown. A space normally used as a media center is used as an alternate EOF.

San Onofre Unit 2 was manually tripped from 97% power due to the loss of feed water pumps. After both feedwater pumps tripped, the operators manually tripped the reactor. Both trains of the emergency feed water system actuated as expected due to the initial power level. The plant is stable at NOP/NOT. The cause of the feed water pump trips is being evaluated. All control rods fully inserted and all safety systems worked properly. The steam generators are discharging steam to the main condenser using the turbine bypass valves. AFW pumps are running to maintain steam generator water levels.

"THIS IS AN 8-HOUR NOTIFICATION TO REPORT A VALID ESF SIGNAL TO START 1C EMERGENCY DIESEL GENERATOR THAT OCCURRED ON 4/11/04 AT 0023. Salem Unit 1 is defueled. The spent fuel pool cooling system is providing decay heat removal. Spent fuel pool temperature is being maintained at 106 degrees. RCS temperature is 75 degrees. The RCS is vented to atmosphere. Reactor level is 97.5 feet. 1C emergency diesel generator is cleared and tagged for maintenance. 13 station power transformer was returned to service on 4/10/04 at 2347. The operating crew briefed expected response and abnormal procedures if the 4kv vital bus did not transfer during the retest of 13 station power transformer. Operations successfully retested 1A and 1B 4kv vital bus transfer from 14 station power transformer to 13 station power transformer and back to 14 station power transformer in accordance with station operating procedures. Operations attempted to retest the 1C 4kv vital bus transfer from 14 station power transformer to 13 station power transformer. When the operator attempted to close 13CSD infeed breaker, the 14CSD infeed breaker opened as designed, but 13CSD breaker failed to close. The 1C 4kv vital bus deenergized due to both offsite power source infeed breakers opening and 1C emergency diesel generator unavailable. An ESF signal to start the 1C emergency diesel generator was provided by the safeguards equipment cabinet {SEC}. Since the 1C emergency diesel was cleared and tagged for maintenance, it did not start. The cause of the failure to transfer is not known at this time. The operating crew implemented the appropriate abnormal operating procedures for the de-energized 1C 4kv vital bus. Operator and plant response was as expected. Decay heat continues to be removed by the spent fuel pool cooling system. Outage incident response team is evaluating and troubleshooting the cause of the loss of power to 1C 4kv vital bus. ORAM risk remains yellow. There were no personnel injured during the event."
