| "Description of event: The licensee reported the loss of a Troxler           |
| moisture/density gauge and company truck when a technician failed to report  |
| to a designated job site. The gauge is a Troxler Model 3440, serial number   |
| 21935. It contains approximately 8 millicuries of Cesium 137 (source serial  |
| number 75-3524) and approximately 40 millicuries of Americium-Beryllium      |
| (source serial number 47-17271). The company vehicle is a 1999 white Ford    |
| F-150 extended cab pickup, company number 50, Arizona license [ ]. The Tempe |
| police have been notified and are investigating. The company is offering a   |
| $250 reward for information leading to the return of the gauge and truck.    |

| "D.C. Cook Unit One declares entry and exit of an Unusual Event due to       |
| Reactor Coolant System leakage of greater than 25 gallons per minute. On     |
| June 5 @ 23:00 while performing an 18 month surveillance [1-IHP-4030-102-017 |
| 'Pressurizer PORV/Actuation Channel Calibration with Valve Operation'] on    |
| the Pressurizer Power Operated Relief Valves (PORVs) an unblocked PORV       |
| lifted and discharged to the Pressure Relief Tank (PRT) for approximately 15 |
| seconds. This lifting discharged approximately 100 gallons to the PRT. The   |
| Initiating Condition for this Unusual Event is Reactor Coolant System        |
| leakage greater than 25 gallons per minute.                                  |
|                                                                              |
| "The plant is and was in Mode 4. Conditions remain stable after manual       |
| isolation of the PORV with the Control Switch of the Block Valve by the      |
| assisting Reactor Operator."                                                 |

| The licensee attributed this occurrence to the recently revised procedure    |
| identified above which did not address blocking the other PORVs during       |
| testing.  The licensee informed state and local agencies and the NRC         |
| Resident Inspector.                                                          |

| BJ Services, an oil field service company, determined that a general         |
| licensed source could not be located.  The source,  250 mCi Cs-137 sealed in |
| special form manufactured circa 1984, was installed in a Kay Ray Model 7063  |
| instrument, S/N 28820, used for slurry density measurements.  The last       |
| recorded location was Rock Springs, WY, on September 8, 1990 for a leak      |
| test.  The instrument was then owned by Western Company which was acquired   |
| by BJ Services in 1995.  BJ Services has discussed this incident with        |
| R4(Donovan) and will continue their investigation.                           |

| The reactor tripped due to a turbine trip due to a main generator trip       |
| caused by a high vibration on the main generator primary water pump shaft.   |
| All systems functioned properly.  The plant is stable in Mode 3 with steam   |
| generator level being maintained with auxiliary feedwater (started           |
| automatically on low steam generator level) and excess heat being removed    |
| via the steam bypassed to the main condenser.                                |
|                                                                              |
| Primary water pump vibration trip is a 2 out of 2 channel coincidence.       |
| There was no indication of high vibration on the plant recorder.  At the     |
| time of the trip, an investigation was ongoing on one of the channels that   |
| was in alarm.  An investigation continues into the sensors and circuits      |
| associated with the high vibration trip.  The plant will remain in Mode 3    |
| until the problem is identified and corrected.                               |
|                                                                              |
