| During the afternoon of September 16, 2002, a roof moisture gauge in its     |
| locked case was stolen from a locked van belonging to an Illinois            |
| Radioactive Material Licensee--IL Roof Consulting Associates, Inc. with      |
| license IL-01713-01.  The Radiation Safety Officer (RSO) reported the        |
| break-in and theft to the IDNS and the Chicago Police within an hour of the  |
| theft.  The gauge was a Troxler Model 3216, Serial Number 00173 with 40      |
| millicuries of americium-241and was used for roofing moisture measurements.  |
| The van was parked in front of a Chicago public school while two workers     |
| were on the roof of the school--Leif Ericson Scholastic Academy--at 3600 W.  |
| 5th Avenue, Chicago.  Near the end of the job the RSO had joined the two     |
| workers and then discovered the theft that occurred approximately 1435 as he |
| was returning to the van with a second gauge that had been in use.  The      |
| windows of the van were tinted to reduce visibility except for the drivers   |
| side window.                                                                 |

| INADVERTENT ACTUATION OF BLACKOUT SIGNAL ON UNIT 1 DURING SURVEILLANCE       |
| TESTING                                                                      |
|                                                                              |
| "Inadvertent Actuation of B Train Blackout Signal on Unit 1. Actuation       |
| occurred during testing of the 1B Diesel Generator sequence panel. The       |
| actuation caused the B Train Nuclear Service Water System to realign to the  |
| standby Nuclear Service Water Pond on both Unit 1 and Unit 2. Unit 2 was not |
| affected due to the realignment. The Unit 1 Boric Acid pump transfer pump    |
| automatically secured and various containment and Auxiliary Building         |
| Ventilation components were affected due to the actuation. The procedure     |
| used for testing the sequencer simulated an undervoltage signal on the B     |
| Train Emergency Bus. Plans are being evaluated to restore the sequencer from |
| the test alignment and realign all affected equipment."                      |
|                                                                              |
| Reactor residual heat removal cooling was not affected by this event. Spent  |
| fuel pool cooling was not affected by this event. Electrical buses remained  |
| energized and no EDG autostart occurred since the blackout signal was        |
| simulated and not based on an actual undervoltage condition.  The licensee   |
| is attributing the cause preliminarily to an inadequate procedure.           |
|                                                                              |
| The licensee will notify the NRC Resident Inspector.                         |
