The following information was provided via email:
"At 7:00 p.m., June 8, 2004, Materials Testing of Arkansas, Inc., Arkansas Radioactive Materials License Number ARK-859-BP-03-02, notified the Arkansas Department of Health, of a missing Troxler Electronic Laboratories, Inc., Model 3430 moisture density gauge, serial number 26636, containing 44 millicuries of Americium-241: Berylium, and 9 millicuries of Cesium-137. The licensee stated that the gauge had fallen out of the truck during transport from a job site in Conway, Arkansas.
"The Conway Police Department, Faulkner County Sheriff's Office, Arkansas State Police and the Arkansas Department of Emergency Management were notified.
"At 7:00 a.m., June 9, 2004, Materials Testing of Arkansas, Inc. reported the gauge had been recovered and was being returned to the storage location. The gauge was recovered by another Arkansas Radioactive Material Licensee who secured the gauge overnight. The gauge does not appear to have been tampered with or damaged.
"The Department is investigating the incident and will provide follow-up information upon receipt of the licensee's formal notification report." |

On the afternoon of 06/08/04, a Troxler moisture density gauge (model/serial number not yet known) was run over by a pickup truck at a construction site in Rayham, MA. The source rod was detached but not bent. The area was cordoned off and the licensee RSO was notified. The RSO arrived, positioned the source rod back into the gauge, secured the gauge and performed a radiological survey with negative results. The results of a source leak test are pending. |

On June 14, 2004, at approximately 07:44 Mountain Standard Time (MST) all three units at the Palo Verde Nuclear Generating Station experienced automatic reactor trips coincident with a grid disturbance and loss of offsite power in the Palo Verde Switchyard. Unit 2 declared an ALERT Emergency Plan classification at approximately 07:54 due to a loss of AC power to essential buses reduced to a single power source for greater than 15 minutes such that any additional single failure would result in a station blackout. Subsequently, at 09:51 Unit 2 downgraded the Emergency Plan classification to a NOTIFICATION OF UNUSUAL EVENT when AC power was restored from a single essential bus to both essential buses. Units 1 and 3 declared a NOTIFICATION OF UNUSUAL EVENT at 07:53 MST due to a loss of offsite power to essential buses for greater than 15 minutes. The NOTIFICATION OF UNUSUAL EVENT was terminated for all 3 units at 12:07 MST.
Unit 1 and 2 manually initiated a Main Steam Isolation System ESF actuation by procedure. Unit 3 received an automatic Main Steam Isolation System ESF actuation.
Due to the loss of offsite power, the Emergency Plan Technical Support Center (TSC) was unavailable. The Unit 2 Satellite TSC was to be staffed by the Emergency Response Organization in response to the loss of assessment capability. Power to the TSC has since been restored.
The Emergency Plan ALERT declaration includes staffing of the Joint Emergency New Center to address expected media interest.
All three units were at normal operating temperature and pressure prior to the trip. All CEAs inserted fully into the reactor cores. All Emergency Diesel Generators (EDGs) (2 per unit) associated with each of the 3 units started as expected in response to the loss of offsite power to their safety buses. Unit 2's train "A" EDG started, but did not indicate volts or amps and was manually shutdown.
The offsite power grid had several perturbations for approximately one hour following the event but has been stable since. LCO 3.8.1, AC Sources - Operating, was entered in each unit as a result of this event. Heat removal is to atmosphere via atmospheric dump valves in natural circulation. Main steam safety valves may have lifted for a brief time. Restoration of forced reactor coolant circulation is pending assurance that the offsite power grid can reliably support the load. No major equipment was inoperable prior to the event that contributed to the event.
All 3 units are stable at normal operating temperature and pressure in Mode 3. The event did not result in any challenges to fission product barriers and there were no adverse safety consequences as a result of this event. The event did not adversely affect the safe operation of the plant
NRC Resident Inspector was notified.
FBI Jeff Muller and Mr. Rosales (Mexican National Commission of Nuclear Safety and Safeguards {CNSNS}) were notified.

"On June 14, 2004 at 0741 PDT, the offsite power grid connected to San Onofre experienced a system disturbance. Grid frequency dipped to about 59.7 Hz or slightly lower, and then recovered about three minutes later. Plant Operators declared offsite power inoperable. Southern California Edison is conservatively reporting this event in accordance with 10 CFR 50.72(b)(3)(v)(D). The diesel generators for both Units 2 and 3 were operable during this event. At the time of this report, Units 2 and 3 continue to operate at about 100% power."
