| INOPERABLE SECONDARY CONTAINMENT                                             |

| "On 3/20/03 at 0015 hours during performance of Secondary Containment        |

| drawdown testing, it was determined that the Technical Specification maximum |

| allowed combined flowrate of 2885 SCFM for Zone 1 and Zone 3 was exceeded.   |

| The average flow for the two zones was approximately 3000 SCFM. The          |

| condition required the Station to declare both zones inoperable, and placed  |

| Unit 1 in a 4 hour LCO to restore Secondary Containment. Unit 2 is already   |

| in Mode 5, however the condition would have prevented all additional fuel    |

| moves. The Standby Gas Treatment System was capable of maintaining the DP    |

| requirement of 0.25 " vac. water gauge during the test. By 0330              |

| investigation had reduced flow from the two zones to approximately 2600      |

| SCFM, and the LCO was exited. The inoperability of Secondary Containment is  |

| a loss of an entire Safety Function that is needed to control the release of |

| radioactive material, and is reportable under 10CFR50.72(b)(3)(v)(c)."       |
