| LOSS OF A SAFETY FUNCTION DUE TO ALL FOUR EMERGENCY DIESEL GENERATORS BEING  |
| DECLARED INOPERABLE                                                          |
|                                                                              |
| The following information was received from the Licensee via facsimile:      |
|                                                                              |
| "At 0145 hours [EST] on 2/1/2003, all four Emergency Diesel Generators       |
| (EDGs) were declared inoperable following discovery of a Fuel Oil leakage    |
| drain path change that was installed to prevent Fuel Oil leakage from        |
| reaching the ground water.                                                   |
|                                                                              |
| "This change involved the installation of plastic sleeves on the fuel oil    |
| drains for all four EDGs to reroute the fuel oil drains to a catch basin.    |
| The normal drain path is through the RHR [Residual Heat Removal] Complex     |
| (which houses the EDGs) drain system to the chemical pond.  This change was  |
| installed after a crack was discovered in a 21 inch concrete line in the     |
| drain path from the RHR Complex Drain Sump to the Chemical Pond. This change |
| was installed on 01/17/03.                                                   |
|                                                                              |
| "While running EDG 11 for post maintenance testing following a scheduled     |
| maintenance outage, fuel oil in a drain sleeve backed up and spilled out of  |
| a vent on the fuel oil drain header.  This spillage resulted in a small      |
| lagging fire.  EDG 11 was immediately shutdown and the fire was extinguished |
| within a few minutes.  No significant damage to EDG 11 was caused by the     |
| fire.  Since all four EDGs had a similar fuel oil drain configuration, they  |
| were declared inoperable at 0145 hours and Technical Specification 3.8.1,    |
| Condition B was entered, which requires restoration of one division of the   |
| EDGs within 2 hours.                                                         |
|                                                                              |
| "At 0329 hours, the normal fuel oil drain configuration was restored for EDG |
| 13 and EDG 14 (Division 2) and Technical Specification 3.8.1, Condition B    |
| was exited.  At 0345 hours, the normal fuel oil drain configuration was      |
| restored for EDG 12 (Division 1). EDG 11 remains inoperable until the        |
| completion of post maintenance testing.                                      |
|                                                                              |
| "This notification is being made in accordance with 10CFR50.72(b)(3)(v)[(D)] |
| due to all four EDGs being inoperable causing the loss of a safety           |
| function."                                                                   |
|                                                                              |
| The fire was extinguished without offsite assistance and there were no       |
| injuries due to the fire.                                                    |

|                                                                              |
| *** RETRACTION AT 1118 EST ON 3/13/03 FROM PATRICK FALLON TO ERIC THOMAS     |

| "While running EDG (Emergency Diesel Generator) 11 for post maintenance      |
| testing following a scheduled maintenance outage on February 1, 2003, fuel   |
| oil in a drain sleeve backed up and spilled out of a vent on the fuel oil    |
| drain header. This spillage resulted in a small fire. The fire caused no     |
| damage to EDG 11. Since all four EDGs had a similar temporary fuel oil drain |
| configuration, they were declared inoperable. The normal fuel oil drain      |
| configuration was restored within the Completion Time of Technical           |
| Specification 3.8.1, Condition B.  Notification was made in accordance with  |
| 10 CFR 50.72(b)(3)(v) due to all four EDGs being declared inoperable causing |
| the loss of a safety function.                                               |
|                                                                              |
| "The cause of the fire is believed to be excessive fuel oil leaking from the |
| EDG 11 fuel injector compartment onto the exhaust manifold. (The cause was   |
| initially reported as normal fuel injector leakage backing up into the fuel  |
| oil drain header due to the temporary drain configuration). The injectors    |
| allowed an abnormally high rate of fuel oil leakage into the fuel oil drain  |
| header for EDG 11 only. The fuel oil drain rates for EDGs 12, 13, and 14     |
| were observed to be normal during subsequent surveillance testing, and       |
| within the capability of the temporary fuel oil drain configuration.         |
|                                                                              |
| "Therefore, EDGs 12, 13, and 14 were capable of performing their safety      |
| function and there was no common mode failure, as a result of the temporary  |
| drain configuration. This condition is therefore not reportable under 10 CFR |
| 50.72(b)(3)(v). The original notification, Event Number 39554, is            |
| retracted."                                                                  |
|                                                                              |

| ERROR IN THE CURRENT SAFETY ANALYSIS FOR A STEAM GENERATOR TUBE RUPTURE      |
|                                                                              |
| "On March 13, 2003 while operating at 100% power, Callaway Plant determined  |
| a problem existed in the current safety analysis for a steam generator tube  |
| rupture accident accompanied by an overfill condition of the ruptured steam  |
| generator. This problem was discovered while reviewing a future plant        |
| modification package.   The current FSAR analysis concluded that an overfill |
| condition would not occur during a tube rupture accident.                    |
|                                                                              |
| "Through investigations instigated during the modification review process,   |
| it was determined that for current plant conditions, an overfill condition   |
| could result if an auxiliary feedwater control valve supplying the ruptured  |
| steam generator were to fail open.   In this case, it was concluded that the |
| ruptured steam generator would overfill and water would be released through  |
| the steam generator safety valves, resulting in a radioactive release to the |
| environment greater than allowed by regulatory guidance.   Since this        |
| accident was not adequately incorporated in the FSAR, specific procedural    |
| time limits for operator actions had not been developed.   This lack of      |
| credited operator time limits coupled with past plant modifications result   |
| in a potential to exist for the ruptured steam generator overfill scenario.  |
|                                                                              |
| "Current Technical Specifications allow a reactor coolant system Dose        |
| Equivalent Iodine (DEI) value of 1.0 microcurie per gram.  To assure         |
| compliance with existing regulatory guidance, plant procedures have been     |
| changed to administratively reduce the steady state DEI limit to 0.3         |
| microcurie per gram, a value that has not been exceeded in the last three    |
| years. Current steady state DEI concentration in the reactor coolant system  |
| is 0.001769 microcurie per gram.  The new lower DEI limit will ensure that   |
| if an overfill condition were to occur during a steam generator tube         |
| rupture, post accident radiological consequences would not exceed the limits |
| imposed by the FSAR and the Standard Review Plan."                           |
|                                                                              |
