| Event occurred on May 20, 2003 between the hours of 0200 and 0230 hours CDT  |

| at the Amoco Refinery in Texas City, TX. Overexposure was reported to the    |

| Texas Dept. of Health on July 3, 2003.                                       |

| "A radiography source was not cranked into the fully shielded position       |

| resulting in a 6.403 R whole body exposure to a radiographer.  The           |

| radiographer was making wall thickness exposures using a 100 curie cobalt 60 |

| source with a directional collimator.  The radiographer made the last        |

| exposure for the night, then proceeded to retrieve the film and take it for  |

| development in the darkroom.  The radiographer believed the pigtail had been |

| fully retracted, however, his initial survey was not conclusive because his  |

| survey meter was not turned on.  Although the ratemeter was alarming,        |

| because of the noise level and the ear plugs, he did not initially hear      |

| ratemeter alarming.  When he did hear the faint ringing he checked the meter |

| and it was off. When the radiographer turned the meter on and resurveyed the |

| guide tubes, the needle went off-scale.  He checked his pocket dosimeter and |

| it was off scale.  The radiographer then retracted the pigtail into the      |

| fully shielded position.  The radiographers reported the event to their      |

| management by telephone, then returned to the company shop.                  |

| "The following day the personnel monitoring badge was sent for emergency     |

| processing.  The radiographer believes he was exposed for about one minute.  |

| "At 1500 on 07/07/2003, Operations received a revised Functional Evaluation  |

| concerning a Unit 1 Appendix R Analysis which affected both Units 2 & 3. It  |

| was identified that a Reactor Building fire could fault a Recirc Pump Motor  |

| Generator (MG) Set supply cable/control power cable and cause a loss of the  |

| control power required to trip the breaker. Upon further review, it was      |

| determined that the 250v dc control power associated circuit for the Recirc  |

| Pump Board breaker trip circuit does not have adequate separation from the   |

| 4KV feeder cable to the Recirc Pump MG Set (Unit 3) or the Variable          |

| Frequency Drive (Unit 2). A fire propagating to the Cable Spreading Room     |

| from the Reactor Building may affect safe shutdown circuits and remains      |

| unanalyzed. Roving Fire watches were established in the affected areas on    |

| both Units 2 & 3.                                                            |

| MANUAL ACTUATION OF A SAFETY SYSTEM DUE TO UF6 CYLINDER LEAKAGE              |

|                                                                              |

| "On 07/07/03 at 1100 hrs the Plant Shift Superintendent's (PSS) office was   |

| notified by operations personnel at the X344 facility, that during the       |

| initiation of UF6 transfer from Autoclave #3 to the daughter cylinder, smoke |

| was observed emitting from between the cylinder valve stem and packing       |

| gland. The operator attempted to shut the cylinder valve, but discovered     |

| that the stem would continue to turn in the closing direction well beyond    |

| its normal expected shut position.  Out gassing continued to be observed     |

| emitting from between the cylinder valve stem and packing gland. The First   |

| Line Manager, observing the evolution directed the Operator to press the     |

| Emergency Closure Button placing autoclave #3 into containment. This was     |

| manual actuation of Safety Equipment used to mitigate (prevent) a release of |

| UF6.  Emergency Response was initiated and the Gas Release Alarm was         |

| activated to evacuate the building, which placed the other in service        |

| autoclave into containment.  All Air monitoring was less than detectable for |

| HF and below Plant Allowable Limits for Beta and Gamma."                     |

| AUTOMATIC REACTOR SCRAM AT LaSALLE UNIT 2 DUE TO TRIP OF THE MAIN TURBINE    |

|                                                                              |

| "At 2319 CDT on July 7, 2003 LaSalle Unit 2 Automatically scrammed due to a  |

| trip of the main turbine. The main turbine trip was caused by a main lockout |

| due generator to a fault on the "B" phase of the main power disconnect. All  |

| rods inserted on the scram. Three safety relief valves actuated in the       |

| relief mode on the turbine trip. Both reactor recirc pumps tripped off and   |

| all three circulation water pumps tripped off. The main steam line isolation |

| valves and main steam line drains were closed due to the loss of the         |

| circulating water pumps. Tech Spec 3.0.3 was entered due to simultaneous     |

| inoperability of A, B, and C residual heat removal pumps. "A" residual heat  |

| removal pump was declared inoperable due to use in suppression pool cooling. |

| "B" and "C" residual heat removal pumps were inoperable at the beginning of  |

| the event for planned preventative maintenance on the essential core cooling |

| system ventilation. There were no automatic actuations of ECCS systems and   |

| no primary or secondary containment isolation system actuations. There was   |

| no ECCS injections into the reactor vessel. There were 3 subsequent auto     |

| scram signals on low reactor level due to level shrink on SRV closure in     |

| pressure control."                                                           |

|                                                                              |

| Unit 2 is currently stable with reactor feedwater being provided by the      |

| condensate system and reactor heat removal using SRV steam discharge to the  |

| suppression pool. Residual heat removal pumps "A" and "B" are operating to   |

| provide suppression pool cooling. "C" residual heat removal pump has been    |

| returned to operable status. All emergency diesel generators are available.  |

|                                                                              |

| The licensee also reported that the electrical system transient resulted in  |

| the need to reduce power on LaSalle Unit 1 from 100% to ~92% to stabilize    |

| condensate booster pump suction pressure.                                    |

|                                                                              |

| The licensee has notified the NRC Resident Inspector                         |
